In this episode I discuss why it’s important for us to know the history of our understanding that burning fossil fuels and the way our governments have responded – or failed to respond to – that understanding. Then I illustrate that climate timeline with direct, published quotes from people and reports from the last 60-plus years – letting the people of each decade tell the story of their relationship to climate in their own words. It’s my hope that this episode will give you a better basis for judging whether the current responses of our governments are adequate to the task of averting the worst catastrophic climate consequences.

Closing Thoughts on Our Climate Timeline

 

Bearing Witness to How Long We’ve Known but Failed to Act

This is a Facing the Truth Episode. When we practice Facing the Truth, we set aside time and space for bearing witness to the truth of the climate and ecological emergency, in order to truly absorb it and allow it to touch our hearts and minds. We may think the way to peace of mind is to keep the emergency safely compartmentalized in our psyche, occasionally glimpsing over at it but for the most part ignoring it. But the approach of denial comes at high spiritual, emotional, and psychological cost. Part of us remains aware of what’s going on and we experience a subtle but pervasive sense of dread and anxiety. Part of us feels guilty or crazy for living in denial, and we end up shutting down some of our natural empathy, compassion, and sense of connectedness to nature and all living things. Fortunately, if we make a practice of Facing the Truth – mindfully balancing it with Staying Strong and Taking Action – we find that it’s not as traumatic as we might have expected, and it has substantial benefits.

Today I want to bear witness to the fact that the people in power in our world have known exactly what was coming with respect to global heating and its catastrophic consequences for at least fifty years. Now, we can hear that fact stated and let it flow in one ear and out the other with it impacting us much. If you’re anything like me, you hear that scientists have been predicting global heating and ecological collapse due to the burning of fossil fuels for fifty years, but you reflexively minimize the statement in your mind. Maybe it was just a few fringe scientists who speculated that global heating was possible. Maybe the scientists published obscure papers about their concerns and no one knew about them. Maybe there was widespread disagreement about whether burning fossil fuels would really be that bad. Maybe those in power heard about global heating but had no other choices than the ones they made – maybe there were no other options than ending up where we are now.

In reality, though, the science has been pretty clear from the beginning. Global warming is one of those things you might as describe as “not being rocket science.” Although it’s difficult for human beings to wrap their minds around being able to influence the climate of the entire planet with their everyday activities, the increasing and unceasing emission of greenhouse gasses into our atmosphere is like slaughtering an animal species faster that it can reproduce. Or dumping all your garbage into the ocean. Or destroying one ecological system after another to extract resources for profit. Once you understand the very basic physics of the situation, even a small child can stand back and observe, “Hey, if you keep doing that, eventually you’re going to face a really ugly situation, aren’t you?” Do something with harmful, cumulative effects long enough and there will be a reckoning. You will inevitably drive species to extinction, end up swimming in your own garbage, and find yourself struggling to survive because the ecosystems that used to support you are dead.

Most adults in the developed world – and the wealthy few in developing nations – are partly culpable for the fact that there has been almost no attempt to prevent our climate and ecological emergency over the last few decades. We have continued to enjoy the benefits of systems based on burning fossil fuels, overexploiting resources, and degrading ecosystems. However, it’s very important for all of us to realize that there are much larger forces at work here than the desire of the average person for comfort and pleasure.

 

The Climate Timeline: A That Crisis Didn’t Need to Happen

For the last forty or so years, governments in developed nations, multinational corporations, and the ultrarich have – in many cases deliberately and knowingly – kept us on a course heading straight for climate disaster. These “inactivists” have been deeply invested in keeping us dependent on sources of energy, food, and other resources that maximize their profits, while carefully fighting or minimizing concerns about the fact that these sources pump greenhouse gasses into our atmosphere. The inactivists have diligently obstructed or dismantled projects that would have gradually shifted us away from carbon-intensive activities over the last 30 years – a shift which would have been much easier and less costly than the radical changes we now need to undertake, and a shift which would have significantly decreased the severity of the climate-related destruction and suffering we are now experiencing and will experience in the near future.

It did not have to be this way. Renewable, low-carbon energy, sustainably managed natural resources, sustainable farming, equitable distribution of wealth, efficient, low-carbon transportation – all of these things have been well within our reach for the last fifty years. The idea that it was necessary to burn our way into the climate emergency in order for ordinary people to live happy and comfortable lives is nothing other than a massive lie fed to the public by the inactivists so we would go along with their plan.

Sadly, the only reason we’re waking up to the climate crisis now is because we are witnessing or experiencing the destructive effects of global heating every day. Do you realize how bad things have gotten for the effects of global heating to be evident to the naked eye? For the changes in weather, climate, ecosystems, wildlife distribution, disease spread, and farming to be obvious and observable to the average person, even if they’re not trying to pay attention to the state of the so-called “environment?” Scientists predicted exactly what’s happening now decades ago, but they desperately hoped we would never actually see the day. That fact that we all can observe climate change firsthand now is a sign that our biosphere should be rushed to intensive care.

As I mentioned in the last episode, The Trap of Green Consumerism, it’s essential that we stop blaming ourselves for the climate and ecological emergency and demand those with power stop sacrificing our lives to amass even more obscenely unnecessary wealth. We should pressure the ultrarich and multinational corporations, but ultimately, they don’t owe us anything and can be expected to milk the carbon cow up until the last possible second. Our governments, however, are meant to protect us and look out for our interests. It’s absolutely unacceptable that they continue to subsidize and enable carbon-intensive systems that are already causing untold human misery.

For the people in power, inaction over the last fifty years was not a matter of lack of knowledge or doubt about the science, although they will claim that’s the case. That’s what I aim to illustrate in today’s episode. I’m going to give you a relatively brief timeline of the history of our understanding of how the human emission of greenhouse gasses would inevitably lead to catastrophic global heating, and our understanding of what we needed to do about it. As I mentioned earlier, I wanted to illustrate that history with direct, published quotes from people and reports from the last 60-plus years – letting the people of each decade tell the story of their relationship to climate in their own words. This is, of course, far from a full history, and focuses on what we knew – not on government action or inaction on the climate issue over time, or the persistent and deliberate efforts to undermine action on climate by those invested in business as usual. To learn more about the history of the human relationship to climate, check out Nathaniel Rich’s book Losing Earth or Alice Bell’s Our Biggest Experiment: An Epic History of the Climate Crisis.

As I share quotes I will name the source, but full citations and links for all of this episode’s content can be found on the episode page of the Climate and You website. Now, settle back and enjoy our trip through time. For anyone listening to this in the future, note that this was published in 2022.

 

1908 – 114 Years Ago – Arrhenius predicts industry will cause global warming

Henry Ford’s Model T goes on sale for $850

Swedish physicist Svante Arrhenius writes about CO2 – which he refers to as carbonic acid – in his book, “Worlds in the Making”:

“To a certain extent the temperature of the earth’s surface, as we shall presently see, is conditioned by the properties of the atmosphere surrounding it, and particularly by the permeability of the latter for the rays of heat…

“If the quantity of carbonic acid [CO2] in the air should sink to one-half its present percentage, the temperature would fall by about 4°; a diminution to one-quarter would reduce the temperature by 8°. On the other hand, any doubling of the percentage of carbon dioxide in the air would raise the temperature of the earth’s surface by 4°; and if the carbon dioxide were increased fourfold, the temperature would rise by 8°…

“Although the sea, by absorbing carbonic acid, acts as a regulator of huge capacity, which takes up about five-sixths of the produced carbonic acid, we yet recognize that the slight percentage of carbonic acid in the atmosphere may by the advances of industry be changed to a noticeable degree in the course of a few centuries.”[i]

 

1959 – 63 Years Ago – Teller warns the American Petroleum Institute about melting ice caps

Hawaii is admitted as the 50th U.S. State – Global atmospheric concentration of carbon dioxide is measured reliably for the first time by C. David Keeling and is 315ppm [ii] (as humans evolved during the past several hundred thousand years, atmospheric CO2 cycled between about 200 and 300ppm [iii])

Physicist Edward Teller gives a speech at a symposium organized by the American Petroleum Institute and the Columbia Graduate School of Business, which includes over 300 government officials, oil industry executives, scientists, historians, and economists:

“Ladies and gentlemen, I am to talk to you about energy in the future. I will start by telling you why I believe that the energy resources of the past must be supplemented. First of all, these energy resources will run short as we use more and more of the fossil fuels. [….] But I would […] like to mention another reason why we probably have to look for additional fuel supplies. And this, strangely, is the question of contaminating the atmosphere. [….] Whenever you burn conventional fuel, you create carbon dioxide. [….] The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it?

“Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect [….] It has been calculated that a temperature rise corresponding to a 10 per cent increase in carbon dioxide will be sufficient to melt the icecaps and submerge New York. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe.”[iv]

 

1965 – 57 Years Ago – President Johnson’s Science Advisory Committee predicts significant climate changes by the year 2000

Dr. Martin Luther King Jr. leads a civil rights march from Selma to Montgomery, and the first American ground combat troops arrive in Vietnam – Global atmospheric concentration of carbon dioxide reaches 320ppm [v]

President Lyndon B. Johnson’s Science Advisory Committee publishes their “Report on Atmospheric Carbon Dioxide”:

“By the year 2000 the increase in atmospheric CO2 will be close to 25%. This may be sufficient to produce measurable and perhaps marked changes in climate, and will almost certainly cause significant changes in the temperature and other properties of the stratosphere.”[vi]

Frank Ikard, president of the API, speaks about the PSAC report at the annual API meeting:

“This report unquestionably will fan emotions, raise fears, and bring demand for action. The substance of the report is that there is still time to save the world’s peoples from the catastrophic consequence of pollution, but time is running out.

“One of the most important predictions of the report is that carbon dioxide is being added to the Earth’s atmosphere by the burning of coal, oil, and natural gas at such a rate that by the year 2000 the heat balance will be so modified as possibly to cause marked changes in climate beyond local or even national efforts. The report further states, and I quote: ‘… the pollution from internal combustion engines is so serious, and is growing so fast, that an alternative nonpolluting means of powering automobiles, buses, and trucks is likely to become a national necessity.’”[vii]

 

1977 – 45 Years Ago – National Academy of Sciences warns mistakes made now will not be easily rectified

The movie Star Wars is released, and the first home pregnancy test becomes available over the counter – Global atmospheric concentration of carbon dioxide reaches 333ppm [viii]

Frank Press, his chief science adviser to U.S. President Carter and director of the Office of Science and Technology Policy, writes a memo to the president titled “Release of Fossil CO2 and the Possibility of Catastrophic Climate Change:”

“Fossil fuel combustion has increased at an exponential rate over the last 100 years. As a result, the atmospheric concentration of CO2 is now 12 percent above the pre-industrial revolution level and may grow to 1.5 to 2.0 times that level within 60 years. Because of the ‘greenhouse effect’ of atmospheric CO2 the increased concentration will induce a global climatic warming of anywhere from 0.5 to 5°C…

“The potential effect on the environment of a climatic fluctuation of such rapidity could be catastrophic and calls for an impact assessment of unprecedented importance and difficulty. A rapid climatic change may result in large scale crop failures at a time when an increased world population taxes agriculture to the limits of productivity. The urgency of the problem derives from our inability to shift rapidly to non-fossil fuel sources once the climatic effects become evident not long after the year 2000; the situation could grow out of control before alternate energy sources and other remedial actions become effective…

“As you know this is not a new issue. What is new is the growing weight of scientific support which raises the CO2-climate impact from speculation to a serious hypothesis worthy of a response that is neither complacent nor panicky. The authoritative National Academy of Sciences has just alerted us that it will issue a public statement along these lines in a few weeks.”[ix]

Although the memo was stamped “seen by president,” America’s first secretary of energy, James Schlesinger, attached his own note in response:

“​​My view is that the policy implications of this issue are still too uncertain to warrant Presidential involvement and policy initiatives.” [x]

As promised, the Natural Academy of Sciences issued a statement later that month:

“It has become increasingly apparent in recent years that human capacity to perturb inadvertently the global environment has outstripped our ability to anticipate the nature and extent of the impact. It is time to redress that imbalance… Examination of the possible long-term effects of energy use is particularly timely. With the end of the oil age in sight, we must make long-term decisions as to future energy policies. One lesson we have been learning is that the time required for transition from one major source to another is several decades. We cannot make major mistakes and expect to rectify them quickly.”[xi]

1977 and every one of the subsequent 45 years have been seen an average global temperature higher than the 20th century average.[xii]

1979 – 43 Years Ago – First World Climate Conference in Geneva

Global atmospheric concentration of carbon dioxide 336ppm [xiii]

1980 – 42 Years Ago – Jorling argues action should be guided by whether we know enough not to recommend changes in policy

Price of a gallon of gas is $1.22 and John Lennon is shot [xiv] – Global atmospheric concentration of carbon dioxide 338ppm [xv]

Moderator Thomas Jorling, from the published notes of the U.S. National Commission on Air Quality Carbon Dioxide Workshop:

“”Increasing problems facing human society are simply awesome in their dimensions. CO2 build-up, stratospheric changes, massive production and release into the biosphere of long-lived chemicals are all issues descending on us with great speed. To use a poor metaphor, we are flying blind, with little or no idea where the mountains are…

“Often in a gathering like this the refrain is heard as a bench mark for discussion, whether we know enough to recommend a change in policy. That, however, is a seriously deficient guidepost in making judgements on the global impact [of things] such as CO2 build-up, given the speed and momentum of human affairs, given the time requirements and the difficult to even phase in change, given the overriding complexity of the interactions among human activities and their impacts on the life-sustaining environment, given these dynamics and the implications of not acting, we must develop a more responsive guide. And that is whether we know enough not to recommend changes in existing policy.

“The existing policy in this case is the ever-growing combustion of fossil fuels and widespread land clearance which are activities developed not in any way as a result of conscious design or choice, but rather are simply the net result of what we do.

“Thus we are faced with an unavoidable fact: Not recommending policy changes constitutes, either explicitly or by inference, a recommendation to continue present policy.”[xvi]

 

1988 – 34 Years Ago – Hansen testifies before the U.S. Congress that climate change effects are manifesting now

The concept of the World Wide Web discussed for the first time, and the price of a movie ticket is $4 [xvii] – Global atmospheric concentration of carbon dioxide 351ppm [xviii]

James Hansen of the NASA Goddard Space Institute gives testimony to the U.S. Senate Committee on Energy and Natural Resources:

“I would like to draw three main conclusions. Number one, the earth is warmer in 1988 than at any time in the history of instrumental measurements. Number two, the global warming is now large enough that we can ascribe with a high degree of confidence a cause and effect relationship to the greenhouse effect. And number three, our computer climate simulations indicate that the greenhouse effect is already large enough to begin to affect the probability of extreme events such as summer heat waves.

“Causal association requires first that the warming be larger than natural climate variability and, second that the magnitude and nature of the warming be consistent with the greenhouse mechanism…  The warming [we have observed] is almost 0.4 degrees Centigrade by 1987 relative to climatology, which is defined as the 30-year mean, 1950 to 1980 and, in fact, the warming is more than 0.4 degrees Centigrade in 1988. The probability of a chance warming of that magnitude is about 1 percent. So with 99 percent confidence we can state that the warming during this time period is a real warming trend.”[xix]

 

1989 – 33 Years Ago – Companies invested in fossil fuels form the Global Climate Coalition to oppose “drastic and unilateral” remedies to global warming

1989 – The Global Climate Coalition is formed by the National Association of Manufacturers. Members include the American Petroleum Institute and the National Coal Association, and by 1992 included Association of International Automobile Manufacturers, DuPont, Enron, Texaco, and the American Electric Power Service Corporation.[xx] The group opposes “‘drastic and unilateral’ remedies to mitigate global warming,”[xxi] and later opposes ratification of the 1997 Kyoto Protocol.

1992 – 30 Years Ago – The United Nations Framework Convention on Climate Change is signed in Rio by 154 nations

President Bush and Boris Yeltsin meet at Camp David and formally declare the Cold War is over [xxii] – Global atmospheric concentration of carbon dioxide 356ppm [xxiii]

The United Nations Framework Convention on Climate Change is drafted at the United Nations Conference on Environment and Development in Rio de Janeiro, which was signed by 154 states and entered into force in 1994. It states:

“The ultimate objective of this Convention and any related legal instruments that the Conference of the Parties may adopt is to achieve, in accordance with the relevant provisions of the Convention, stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Such a level should be achieved within a time-frame sufficient to allow ecosystems to adapt naturally to climate change, to ensure that food production is not threatened and to enable economic development to proceed in a sustainable manner…

“The Parties should take precautionary measures to anticipate, prevent or minimize the causes of climate change and mitigate its adverse effects.  Where there are threats of serious or irreversible damage, lack of full scientific certainty should not be used as a reason for postponing such measures, taking into account that policies and measures to deal with climate change should be cost-effective so as to ensure global benefits at the lowest possible cost.”[xxiv]

The parties who signed the convention agreed to hold annual meetings called Conferences of the Parties (COPs), where they would report on their anthropogenic greenhouse gas emissions and their progress on the convention’s commitments, including, according to the convention, efforts to:

“…mitigate climate change by addressing anthropogenic emissions by sources and removals by sinks of all greenhouse gases not controlled by the Montreal Protocol, and measures to facilitate adequate adaptation to climate change… Promote sustainable management, and promote and cooperate in the conservation and enhancement, as appropriate, of sinks and reservoirs of all greenhouse gases not controlled by the Montreal Protocol, including biomass, forests and oceans as well as other terrestrial, coastal and marine ecosystems… [and] Promote and cooperate in education, training and public awareness related to climate change and encourage the widest participation in this process, including that of non-governmental organizations.” [xxv]

1997 – 25 Years Ago – Thirty-six countries commit to reducing their greenhouse gas emissions by 5% by 2012 by signing the UN Kyoto Protocol

Princess Diana dies in a car accident and IBM’s “Deep Blue” chess-playing computer defeats chess champion Garry Kasparov – Global atmospheric concentration of carbon dioxide 363ppm [xxvi]

Two months before the UN climate conference in Kyoto, Mobil energy takes out an ad in the New York Times titled “Reset the Alarm,” saying, “Let’s face it: the science of climate change is too uncertain to mandate a plan of action that could plunge economies into turmoil.”[xxvii]

Later in the year, 37 countries commit to limit and reduce greenhouse gases “in accordance with agreed individual targets” by signing the Kyoto Protocol, which operationalized the UN Framework Convention on Climate Change. Part of the protocol states:

“The Parties included in Annex I shall, individually or jointly, ensure that their aggregate anthropogenic carbon dioxide equivalent emissions of the greenhouse gases listed in Annex A do not exceed their assigned amounts, calculated pursuant to their quantified emission limitation and reduction commitments inscribed in Annex B and in accordance with the provisions of this Article, with a view to reducing their overall emissions of such gases by at least 5 per cent below 1990 levels in the commitment period 2008 to 2012… Each Party included in Annex I shall, by 2005, have made demonstrable progress in achieving its commitments under this Protocol.”

The US refuses to ratify the Kyoto protocol in 1998, after “intense opposition from oil companies and the Global Climate Coalition.[xxviii] All remaining 36 countries participating in the Kyoto Protocol complied with it by 2012, but although they reduced their emissions, the total global emissions increased by 32% from 1990 to 2010.

2001 – 21 Years Ago – The IPCC confirms significant warming due to human activities and predicts adverse effects unless greenhouse gas concentrations in the atmosphere are stabilized

September 11th terrorist attack in New York City and Apple introduces the iPod – Global atmospheric concentration of carbon dioxide 371ppm [xxix]

The Intergovernmental Panel on Climate Change, or IPCC, publishes its Third Assessment Report. The IPCC is a scientific body established by the UN in 1988 to report on anthropogenic climate change, its impacts, and possibilities for mitigation. The Third Assessment Report states:

“There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.” (p 5) “Carbon dioxide concentrations, globally averaged surface temperature, and sea level are projected to increase under all IPCC emissions scenarios during the 21st century.” (p 8)

“Projections using the SRES (Special Report on Emissions Scenarios) emissions scenarios in a range of climate models result in an increase in globally averaged surface temperature of 1.4 to 5.8°C (2.52°F to 10.44°F) over the period 1990 to 2100. This is about two to ten times larger than the central value of observed warming over the 20th century and the projected rate of warming is very likely to be without precedent during at least the last 10,000 years, based on paleoclimate data.” (p 8)

“Projected climate change will have beneficial and adverse effects on both environmental and socio-economic systems, but the larger the changes and rate of change in climate, the more the adverse effects predominate.” (p 9) “Overall, climate change is projected to increase threats to human health, particularly in lower income populations, predominantly within tropical/subtropical countries.” (p 9)

“Adaptation has the potential to reduce adverse effects of climate change and can often produce immediate ancillary benefits, but will not prevent all damages.” (p 12) “Greenhouse gas forcing in the 21st century could set in motion largescale, high-impact, non-linear, and potentially abrupt changes in physical and biological systems over the coming decades to millennia, with a wide range of associated likelihoods.” (p 14)

“Inertia is a widespread inherent characteristic of the interacting climate, ecological, and socio-economic systems. Thus some impacts of anthropogenic climate change may be slow to become apparent, and some could be irreversible if climate change is not limited in both rate and magnitude before associated thresholds, whose positions may be poorly known, are crossed.” (p 16)

“Reducing emissions of greenhouse gases to stabilize their atmospheric concentrations would delay and reduce damages caused by climate change.” p 21[xxx]

 

2006 – 16 Years Ago – Stern Review warns inaction will end up being much more costly to economies than action

Facebook becomes open to anyone over age 13, and Al Gore releases the documentary “An Inconvenient Truth” – Global atmospheric concentration of carbon dioxide 382ppm [xxxi]

A report called “The Economics of Climate Change: The Stern Review,” is commissioned by the UK government, published in October:

“The scientific evidence is now overwhelming: climate change is a serious global threat, and it demands an urgent global response. This Review has assessed a wide range of evidence on the impacts of climate change and on the economic costs, and has used a number of different techniques to assess costs and risks. From all of these perspectives, the evidence gathered by the Review leads to a simple conclusion: the benefits of strong and early action far outweigh the economic costs of not acting.

“Climate change will affect the basic elements of life for people around the world – access to water, food production, health, and the environment. Hundreds of millions of people could suffer hunger, water shortages and coastal flooding as the world warms.

“Using the results from formal economic models, the Review estimates that if we don’t act, the overall costs and risks of climate change will be equivalent to losing at least 5% of global GDP each year, now and forever. If a wider range of risks and impacts is taken into account, the estimates of damage could rise to 20% of GDP or more. In contrast, the costs of action – reducing greenhouse gas emissions to avoid the worst impacts of climate change – can be limited to around 1% of global GDP each year.

“The investment that takes place in the next 10-20 years will have a profound effect on the climate in the second half of this century and in the next. Our actions now and over the coming decades could create risks of major disruption to economic and social activity, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century. And it will be difficult or impossible to reverse these changes.”[xxxii]

 

2012 – Ten Years Ago – UN’s Emissions Gap Report demonstrates country climate pledges insufficient to keep global warming below 2°C

Google’s Gmail becomes the world’s most popular email service, and Hurricane Sandy results in 110 deaths and $50 billion in damage and closes the New York Stock Exchange – Global atmospheric concentration of carbon dioxide 394ppm [xxxiii]

From The Emissions Gap Report by the UN Environment Programme:

“The assessment clearly shows that country pledges, if fully implemented, will help reduce emissions to below the Business-as-Usual (BaU) level in 2020, but not to a level consistent with the agreed upon 2°C target, and therefore will lead to a considerable “emissions gap”.

“Emission scenarios analyzed in this report and consistent with a “likely” chance of meeting the 2°C target have a peak before 2020, and have emission levels in 2020 of about 44 GtCO2e (range: 41-47 GtCO2e). Afterwards, global emissions steeply decline (a median of 2.5% per year, with a range of 2.0 to 3.0% per year).”[xxxiv]

 

2014 – 8 Years Ago – IPCC provides detailed predictions of catastrophic consequences of climate change if global greenhouse gas emissions persist

The top song in the US was Happy by Pharell Williams, and Russia invades and annexes Crimea – Global atmospheric concentration of carbon dioxide 398ppm [xxxv]

The IPCC publishes its Fifth Assessment Report:

“Surface temperature is projected to rise over the 21st century under all assessed emission scenarios. It is very likely that heat waves will occur more often and last longer, and that extreme precipitation events will become more intense and frequent in many regions. The ocean will continue to warm and acidify, and global mean sea level to rise…

“Climate change will amplify existing risks and create new risks for natural and human systems. Risks are unevenly distributed and are generally greater for disadvantaged people and communities in countries at all levels of development…

“Climate change is projected to undermine food security (Figure SPM.9). Due to projected climate change by the mid-21st century and beyond, global marine species redistribution and marine biodiversity reduction in sensitive regions will challenge the sustained provision of fisheries productivity and other ecosystem services (high confidence). For wheat, rice and maize in tropical and temperate regions, climate change without adaptation is projected to negatively impact production for local temperature increases of 2°C or more above late 20th century levels, although individual locations may benefit (medium confidence). Global temperature increases of ~4°C or more above late 20th century levels, combined with increasing food demand, would pose large risks to food security globally (high confidence). Climate change is projected to reduce renewable surface water and groundwater resources in most dry subtropical regions (robust evidence, high agreement), intensifying competition for water among sectors (limited evidence, medium agreement).

“In urban areas climate change is projected to increase risks for people, assets, economies and ecosystems, including risks from heat stress, storms and extreme precipitation, inland and coastal flooding, landslides, air pollution, drought, water scarcity, sea level rise and storm surges (very high confidence). These risks are amplified for those lacking essential infrastructure and services or living in exposed areas. {2.3.2}

“Climate change is projected to increase displacement of people (medium evidence, high agreement). Populations that lack the resources for planned migration experience higher exposure to extreme weather events, particularly in developing countries with low income. Climate change can indirectly increase risks of violent conflicts by amplifying well-documented drivers of these conflicts such as poverty and economic shocks (medium confidence). {2.3.2}

“Without additional efforts to reduce GHG emissions beyond those in place today, global emissions growth is expected to persist, driven by growth in global population and economic activities. Global mean surface temperature increases in 2100 in baseline scenarios—those without additional mitigation—range from 3.7°C to 4.8°C (6.66°F to 8.64°F) above the average for 1850–1900 for a median climate response. They range from 2.5°C to 7.8°C (4.5°F to 14.04°F) when including climate uncertainty (5th to 95th percentile range) (high confidence). {3.4}”[xxxvi]

 

2016 – 6 Years Ago – 196 Nations commit to climate action in the Paris Agreement

Playing Pokemon Go becomes a worldwide fad and Donald Trump is elected U.S. President – Hottest Global Temperature since records began in 1880, 0.94°C (1.69°F) higher than the 20th century average [xxxvii] – Global atmospheric concentration of carbon dioxide 404ppm [xxxviii]

The Paris Agreement, adopted at COP21 in December 2015, is entered into force on November 4th 2016. The 196 participating parties agree to aim to limit global warming to well below 2C, and commit to nationally determined contributions (NDC’s) to climate action, including specific targets for the reduction of greenhouse gas emissions and steps to increase resilience and adaptation in response to the negative impacts of climate change. Parties agree to renew commitments to cutting emissions every five years, so the next big Paris agreement meeting was supposed to take place in 2020 but was postponed because of COVID. In 2017 President Trump announces the U.S. withdrawal from the Paris Agreement, calling it “unfair at the highest level to the United States,”[xxxix] but that withdrawal didn’t take effect until November 2020.

2018 – Four Years Ago – IPCC issues a deadline for humanity: 40% reduction in greenhouse gas emissions by 2030 to stay at or below a 1.5°C temperature rise

90 people die in the Camp Fire in California, which destroys the town of Paradise – Sixth hottest Global Temperature since records began in 1880 [xl] – Global atmospheric concentration of carbon dioxide 408ppm [xli]

From the IPCC’s Special Report: Global Warming of 1.5°C:

“Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.

“Climate models project robust differences in regional climate characteristics between present-day and global warming of 1.5°C,and between 1.5°C and 2°C. These differences include increases in: mean temperature in most land and ocean regions (high confidence), hot extremes in most inhabited regions (high confidence), heavy precipitation in several regions (medium confidence), and the probability of drought and precipitation deficits in some regions (medium confidence).

“In model pathways with no or limited overshoot of 1.5°C, global net anthropogenic CO2 emissions decline by about 45% from 2010 levels by 2030 (40–60% interquartile range), reaching net zero around 2050 (2045–2055 interquartile range).

“Pathways limiting global warming to 1.5°C with no or limited overshoot would require rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings), and industrial systems (high confidence)…

“Estimates of the global emissions outcome of current nationally stated mitigation ambitions as submitted under the Paris Agreement would lead to global greenhouse gas emissions in 2030 of 52–58 GtCO2eq yr−1 (medium confidence). Pathways reflecting these ambitions would not limit global warming to 1.5°C, even if supplemented by very challenging increases in the scale and ambition of emissions reductions after 2030 (high confidence). Avoiding overshoot and reliance on future large-scale deployment of carbon dioxide removal (CDR) can only be achieved if global CO2 emissions start to decline well before 2030.”

 

2021 – Last Year – The International Energy Agency says net zero emissions for the global energy sector by 2050 means no investment in new fossil fuel supply projects, and COP26 admits the world is very far from meeting the IPCC’s recommendations

The U.S. rejoins the Paris Agreement – Sixth hottest Global Temperature since records began in 1880, with 12 of the 13 hottest years on record having occurred since 2010, and 19 of the hottest 20 years have been since the year 2000 [xlii] – Global atmospheric concentration of carbon dioxide 416ppm[xliii]

In May, the International Energy Agency (IEA) published a report “Net Zero by 2050: A Roadmap for the Global Energy Sector.” (The IEA is an independent intergovernmental group composed of 31 members countries, established in 1974 after the 1973 oil crisis, and it’s stated mission is “shaping a secure and sustainable energy future for all.”)

“The world has a viable pathway to building a global energy sector with net-zero emissions in 2050, but it is narrow and requires an unprecedented transformation of how energy is produced, transported and used globally, the International Energy Agency said in a landmark special report released today… Building on the IEA’s unrivalled energy modelling tools and expertise, the Roadmap sets out more than 400 milestones to guide the global journey to net zero by 2050. These include, from today, no investment in new fossil fuel supply projects, and no further final investment decisions for new unabated coal plants. By 2035, there are no sales of new internal combustion engine passenger cars, and by 2040, the global electricity sector has already reached net-zero emissions.”[xliv]

According to the Glasgow Climate Pact, the outcome of COP26, the COP:

“Notes with serious concern the findings of the synthesis report on nationally determined contributions under the Paris Agreement, according to which the aggregate greenhouse gas emission level, taking into account implementation of all submitted nationally determined contributions, is estimated to be 13.7 per cent above the 2010 level in 2030.”[xlv] (Recall that the IPCC said we need to be 40% below 2010 levels in 2030.)

The Glasgow Climate Pact then calls upon all parties to return in a year – 2022 – with more ambitious climate goals and plans. One of the things critical to the US being able to keep its promises was the passage of President Biden’s “Build Back Better” bill. Given the U.S. political system, it is essentially impossible for this legislation to pass.

2022 – This Year – U.S. oil production predicted to increase, and governments respond to rising fuel costs with rapid expansion of the extraction and export of natural gas, a fossil fuel incompatible with a pathway to staying under 1.5°C warming

63 years since Teller warned the American Petroleum Institute about climate change; 45 years since Press sent a memo to President Carter warning of “Catastrophic Climate Change; 30 years since the UN Convention on Climate Change was signed in Rio; 4 years since the IPCC gave a deadline for radical action this decade

In a press release dated January 11, 2022, the U.S. Energy Information Administration (EIA) says:

[The EIA] “forecasts that U.S. oil production will average 12.4 million barrels per day during 2023, surpassing the record high for domestic crude oil production set in 2019.

“U.S. coal consumption increased by 14% in 2021 in response to growing demand for coal-fired electricity. EIA expects U.S. coal consumption to decrease by 2% in 2022 and remain relatively unchanged in 2023. Despite the decrease in consumption, EIA forecasts that coal production will increase 6% in 2022.”

In May, carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked at 421 parts per million, “pushing the atmosphere further into territory not seen for millions of years.”[xlvi] Scientists estimate that we need to limit CO2 to 430ppm in order to avoid overshooting our goal of a maximum 1.5°C global temperature increase.[xlvii]

climate timeline

Atmospheric carbon dioxide concentrations over the holocene (yrs. -10.000–2016) from Pixabay https://commons.wikimedia.org/wiki/User:DeWikiMan

From the IPCC report Climate Change 2022: Mitigation of Climate Change:

“Without a strengthening of policies beyond those that are implemented by the end of 2020, GHG emissions are projected to rise beyond 2025, leading to a median global warming of 3.2 [2.2 to 3.5] °C [5.76°F, or 3.96°F – 6.3°F] by 2100.”[xlviii]

June report from Climate Action Tracker, an independent scientific analysis that tracks government action on climate, “Global reaction to energy crisis risks zero carbon transition”:

“There is a dangerous rush to build new LNG infrastructure across the world, not only for European import facilities, but several gas-producing countries are also planning to either ramp up existing export facilities, or build new ones altogether…

Natural gas is not a bridge or transition fuel, this is a common misperception. As with all other fossil fuels, natural gas needs to be phased out as soon as possible to meet the objectives of the Paris Agreement. Under the IPCC’s 1.5°C-compatible scenarios, demand for natural gas should have peaked in 2020 (IPCC, 2018).”[xlix]

As Wikipedia explains clearly: “The extraction and consumption of natural gas is a major and growing contributor to climate change. Both the gas itself (specifically methane) and carbon dioxide, which is released when natural gas is burned, are greenhouse gases. When burned for heat or electricity, natural gas emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil and biomass fuels. However, gas venting and flaring, along with unintended fugitive emissions throughout the supply chain, can result in natural gas having a similar carbon footprint to other fossil fuels overall.”[l]

June 30th: The U.S. Supreme Court rules that the executive branch’s Environmental Protection Agency does not have broad authority to induce a shift to cleaner energy sources at power plants under current legislation.[li]

Closing Thoughts on Our Climate Timeline

Nathaniel Rich, in Losing Earth: A Recent History[lii]:

“If an eventual 5- or 6-degree warming scenario seems outlandish, it is only because we assume that we’ll respond in time. We’ll have decades to eliminate carbon emissions, after all, before we are locked into 6 degrees. But we’ve already had decades—decades increasingly punctuated by climate-related disaster—and we’ve done nearly everything possible to make the problem worse. It no longer seems rational to assume that humanity, encountering an existential threat, will behave rationally.”

Alice Bell, in Our Biggest Experiment: An Epic History of the Climate Crisis[liii]:

“We’ve inherited a position of having to radically change the world’s economy to have even a snowball’s chance in hell of staying anywhere near 2°C, let alone 1.5°C. What’s more, we have to make these enormous changes while also tackling challenging climate change impacts…

“One of toughest things about campaigning on climate change is that you can’t really win, because in many ways we’ve already lost. The more optimistic spin on this is that because climate change happens by degree, there is still always something to fight for. Because 1°C is better than 1.5°C, 1.5°C is better than 2°C, and that will continue to be the case for some time to come.”

 

It’s easy to feel discouraged when you read this climate timeline and contemplate how scientists and economic experts have been warning our governments to take action for over 30 years. I find it especially poignant to hear references in their statements to how the effects of global warming are going to be evident by the year 2000, speaking prophetically about a world we have now personally experienced. It’s also maddening to hear how wise people repeatedly that it would take decades to transition away from fossil fuels, so we should have started in a substantial way in the 1980’s. Recall that the National Academy of Sciences said in 1977:

“With the end of the oil age in sight, we must make long-term decisions as to future energy policies. One lesson we have been learning is that the time required for transition from one major source to another is several decades. We cannot make major mistakes and expect to rectify them quickly.” [liv]

The words from the story I have just told which stick with me the most are those of Thomas Jorling, at the U.S. National Commission on Air Quality Carbon Dioxide Workshop:

“Often in a gathering like this the refrain is heard as a bench mark for discussion, whether we know enough to recommend a change in policy. That, however, is a seriously deficient guidepost in making judgements on the global impact [of things] such as CO2 build-up, given the speed and momentum of human affairs, given the time requirements and the difficult to even phase in change, given the overriding complexity of the interactions among human activities and their impacts on the life-sustaining environment, given these dynamics and the implications of not acting, we must develop a more responsive guide. And that is whether we know enough not to recommend changes in existing policy.” [lv]

It is encouraging that nations of the world have been gathering on a yearly basis for 20 years to tackle climate change, but progress is extremely slow. As our story revealed, even the Paris Agreement falls way short of what’s required. Many Nationally Determined Contributions, or NDCs, are impressive – for example, the U.S. commits to “an economy-wide target of reducing its net greenhouse gas emissions by 50-52 percent below 2005 levels in 2030”[lvi] – but just because a country sets a goal doesn’t it mean it can or will follow through. (You can view a list of each nation’s NDC online at the UN’s Climate Change NDC Registry.) Ambitious goals by some nations, even if met, may be offset by more gradual changes in other countries, such as China, which says it will “strive to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060.”[lvii] Stay tuned for the results of this year’s COP27 in Egypt, where countries will be asked to present more ambitious goals, and where there will be global “stocktake” on progress on the Paris Agreement goals. These goals include not just climate mitigation and adaptation in each country, but also a substantial transfer of funds and technology from developed to developing countries to enable them to meet climate goals while still improving the lives of their citizens.

We all need to be clued into what our governments are doing to transition to a low-carbon future as quickly as possible. We need to hold them accountable to their own promises, recorded conveniently in their Paris Agreement NDCs. If we let another decade or two drift by without commensurate action, the toll of human misery will be incalculable. After all, the misery that has already been caused by 1.1°C of global warming is incalculable – the results of superstorms, megafires, droughts, killer heat waves, water shortages, crop failures, the decline of fisheries, mass migration, the spread of parasites and disease. For all the talk about efforts to limit warming to 1.5°C (2.7°F), we need to remember that this is not a number chosen because it’s healthy for humanity, it’s a number chosen to keep the catastrophe from unfolding faster than we can adapt. We need to make sure our climate timeline involves radical decarbonization over the next few years – something that improve the well-being of all life on this planet.

Thanks for sticking with this episode and bearing witness to the human response to anthropogenic global warming. Just allowing this story into your heart and mind is climate action. I’ll be back next week with a new episode, thanks for listening.
