Arguments
Explaining climate change science & rebutting global warming misinformation
Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn't what happens with climate change denial. Skeptics vigorously criticise any evidence that supports man-made global warming and yet embrace any argument, op-ed, blog or study that purports to refute global warming. This website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?
Explainer: Will global warming ‘stop’ as soon as net-zero emissions are reached?
Posted on 6 May 2021 by Zeke Hausfather
This is a re-post from Carbon Brief
Media reports frequently claim that the world is facing “committed warming” in the future as a result of past emissions, meaning higher temperatures are “locked in”, “in the pipeline” or “inevitable”, regardless of the choices society takes today.
The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions reach zero, meaning humans have the power to choose their climate future.
When scientists have pointed this out recently, it has been reported as a new scientific finding. However, the scientific community has recognised that zero CO2 emissions likely implied flat future temperatures since at least 2008. The Intergovernmental Panel on Climate Change (IPCC) 2018 special report on 1.5C also included a specific focus on zero-emissions scenarios with similar findings.
Much of the confusion around committed warming stems from mixing up two different concepts: a world where CO2 levels in the atmosphere remain at current levels; and a world where emissions reach net-zero and concentrations begin to fall.
Even in a world of zero CO2 emissions, however, there are large remaining uncertainties associated with what happens to non-CO2 greenhouse gases (GHGs), such as methane and nitrous oxide, emissions of sulphate aerosols that cool the planet and longer-term feedback processes and natural variability in the climate system.
Moreover, temperatures are expected to remain steady rather than dropping for a few centuries after emissions reach zero, meaning that the climate change that has already occurred will be difficult to reverse in the absence of large-scale net negative emissions.

Bringing more certainty to uncertainty communications
For the armchair dilettante observer of scientific progress a solid literature review is something akin to going to Disneyland. It's almost too much stimulation. When a review covers a salient, hot topic, so much the better. More seriously, literature reviews are an opportunity for a scientific community to "take stock," identify where commonality of purpose might benefit and where gaps or discontinuities in knowledge are stubbornly lodged or newly developing. For the layperson, a review is a great way to gain a toehold on current understanding.
This week we're pleased to feature a vast review focusing on a key factor controlling public thinking and hence policy progress toward remedying our unfortunate, accidental launching of rapid climate change. "Communications about uncertainty in scientific climate-related findings: a qualitative systematic review" by Astrid Kause et al provides a sweeping view of our best understanding of how people are dealing with the notion of uncertainty when thinking about climate, and how future research might best be directed.
From the review, it's safe to say there's a lot of work left to be done in this arena; research into public thinking about uncertainty and climate change might be termed as in the "generating more questions" as opposed to "answering questions" phase. As well, this field of inquiry affords what might be termed an embarrassment of riches in terms of suggestive, tentative findings begging for followup. Finally, there's a lack of coordination or normalization around much of the mechanical aspect of this research work as practiced, such that forming "big picture" conclusions is somewhat stymied.
Our understanding of uncertainty underpins our thinking about hazards and risks, in the face of what we know are very poor native cognitive skills in producing useful answers when confronted with this trio of probabilistic challenges. Subpar thinking skills in this department lead to bad decisions. Given the need for informed public engagement to drive political energy and - ultimately - useful policy formulation, we face a strong imperative to cement our understanding of and skill in helping the public to accurately perceive and productively think about uncertainty as it concerns climate change. Kause et al is open access, free to read, a diligently constructed snapshot of our present understanding of these matters. From the abstract:
We find that studies of communications about uncertainty in scientific climate-related findings substantially varied in how they operationalized uncertainty, as well as how they measured responses. Studies mostly focused on uncertainty stemming from conflicting information, such as diverging model estimates or experts, or from expressions of imprecision such as ranges. Among other things, users' understanding was improved when climate communications about uncertainty in scientific climate-related findings were presented with explanations about why climate information was uncertain, and when ranges were presented with lower and upper numerical bounds. Users' understanding also improved if they expressed stronger beliefs about climate change, or had better numerical skills. Based on these findings, we provide emerging recommendations on how to best present communications about uncertainty in scientific climate-related findings; and we identify research gaps.

#PLURV - the German #FLICC - getting popular in Germany
Posted on 4 May 2021 by BaerbelW
Longtime readers of what we are up to at Skeptical Science will be well aware of the FLICC taxonomy first suggested by Mark Hoofnagle in 2007, written about in Diethelm & McKnee (2009) and since then greatly enlarged by John Cook:
A much simpler FLICC-taxonomy first started out to be utilized in our MOOC Denial101x where it was used to explain and highlight the techniques used to distort the findings of climate science research. But even then it was pretty clear, that taking this kind of approach could be applied not just to climate science but to many other (science) areas. Right from the start of our MOOC we've had a section in our discussion forums asking the students to come up with FLICC-examples from other areas.
Report: All new cars and trucks in U.S. could be electric by 2035
Posted on 3 May 2021 by Bud Ward
This is a re-post from Yale Climate Connections
Thinking ahead to what (and whether?) you may be driving – may have parked in your garage or driveway or parking lot – a few years from now? Like, for instance, in 2035?
Only with “robust” public policy initiatives as yet not on the books (and perhaps not even on the horizon?), could you find yourself choosing, whether a new passenger car or truck, from among only all-electric vehicles? That’s the case if the findings of a newly released analysis from the University of California, Berkeley, and colleagues are to be believed.
The new reports, by Berkeley scholars and colleagues from the nonprofit group Energy Innovation, find (spoiler alert here: big caveat coming) that with “the right policy” across a number of areas, “all new cars and trucks sold in the United States can be powered by electricity by 2035.” Minus those policy adjustments, the researchers warn, “most of the potential to reduce emissions, cut transportation costs, and increase jobs will not be realized.”
(The sweeping studies described in this piece were made public just prior to news reports that the Biden administration was about to commit to reducing greenhouse gas emissions by about 50% by just the end of this decade, requiring “profound changes at home,” the Washington Post reported.)
Technical and economic hurdles are ‘challenging but achievable’
“Political will, policy, and consumer acceptance – not technical or economic feasibility – are the largest barriers” to be overcome, the report authors write at one point.
In what must seem a blanket endorsement of EV proponents, they say their analyses demonstrate that improved battery technology, costs, manufacturing scale, and industry ambition will accelerate rapid electrification of cars and trucks. And they are not awed by the need to build the extensive battery charging infrastructure needed to support a transition to electric vehicles: All that infrastructure “can be built quickly and cost-effectively,” they write: “The pace of the required infrastructure scale-up is challenging but achievable, and the costs are modest compared with the benefits of widespread EV deployment.”

Skeptical Science collaborates with Repustar to provide Fact Briefs
Posted on 29 April 2021 by John Cook, BaerbelW
We were recently put in touch with Repustar’s founder and CEO Chandran Sankaran, interested in collaborating with Skeptical Science to create climate-related Fact Briefs for their platform. As a new startup, Repustar describe their approach on their About Us page:
Repustar enables everyone to support their conversations online with facts from credible sources. Organizations that contribute to the platform look into the public’s concerns and respond with clear answers supported by credible data and documents.
Repustar combines the tools of journalism and data science to allow well-sourced Fact Briefs to be discovered by the public when and where they are most needed.
News and research organizations with track records of nonpartisanship and evidence-based analyses can contribute their expertise to Fact Briefs, and the platform offers resources to professionals who analyze, create and distribute news.
With people everywhere disoriented about whom to believe and what to trust, Repustar seeks to enable a fact-forward world.
Their evidence-based approach was a good match for Skeptical Science and we began our collaboration with the first step of reviewing a few Fact Briefs drafted by the Repustar team based on some of our rebuttals. We are happy to announce that these initial Fact Briefs have now been published and that Skeptical Science is one of Repustar’s claims reviewing partners.
Repustar’s Fact Briefs are short and to the point, following a common structure where a closed question - answered by either “Yes” or “No” - is posed and answered with a short explanation. Here is an example of how that looks like for one of our Fact Briefs:
Major parties’ climate programs are miles apart
Posted on 29 April 2021 by dana1981
This is a re-post from Yale Climate Connections
President Biden on Earth Day, April 22, unveiled America’s aggressive new climate target: a 50-52% reduction in greenhouse gas emissions below 2005 levels by 2030, on the way to the pledge of net zero emissions by 2050.
That ambitious target would deliver America’s contribution toward meeting the Paris Climate Agreement and the goal of limiting global warming to less than 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial temperatures. President Biden and supportive House Democrats are backing the pledge with a concrete legislative plan to rapidly curb greenhouse gas emissions. That said, important details of the administration’s legislative package remain largely unanswered, and it’s certain to face rough going when, in whatever eventual form, it gets to consideration in the narrowly divided Senate.
In an effort to show that they too care about climate change, House Republicans unveiled their “Energy Innovation Agenda” in the days preceding Biden’s Earth Day announcement. That agenda did not include any specific emissions targets. Rather, it includes a continued reliance on fossil fuels and explicitly opposes putting a price on carbon pollution. It stands in stark contrast to the Democrats’ ambitious plan to meet the Paris climate targets by transitioning to clean energy and leaving fossil fuels in the ground.
Democrats’ plan
House Democrats had been preparing for this moment. In the summer of 2020, the House Select Committee on the Climate Crisis released a comprehensive 547-page report detailing their plan, which analysts estimate would cut greenhouse gas emissions 40% below 2005 levels by 2030 and close to net zero by 2050.
To meet the Paris target of limiting global warming to less than 2°C, global greenhouse gas emissions must reach net zero by around the year 2075, depending on factors like the rate of pollution cuts and the amount of carbon removed from the atmosphere and sequestered underground. Wealthy nations like the U.S. will need to reach net zero emissions even sooner to allow developing countries more time to make the clean energy transition as their economies and energy needs grow. President Biden’s pledge is thus designed to hit a sweet spot: It’s about as fast as America theoretically can move, and fast enough to avert the worst climate consequences. Anything faster would be politically infeasible, but anything slower would be inconsistent with the Paris goals.
The House Democrats’ plan centers around fully decarbonizing the electric grid by 2040 (President Biden has been even more ambitious, calling for a zero-carbon grid by 2035) and electrifying as many other sectors as possible (think electric cars and trucks for transportation and electric heat pumps and appliances for buildings). To that end, the Biden administration and House Democrats have been working to include a clean electricity standard and $1 trillion in clean energy investments as part of their infrastructure legislation.
To pass these measures, the closely divided Senate may well need to try to proceed through the budget reconciliation approach requiring a bare majority 51-50 vote, which could likely require all 50 Senate Democrats to vote in favor, with Vice President Kamala Harris then breaking a tie.
In short, Democrats have an ambitious climate target and a blueprint to begin delivering on it. But there’s no certainty at this point on what specific legislative language can pass both the House and the Senate and earn the President’s signature for enactment.
vEGU21 - EOS7.10 - Science to Action
Posted on 28 April 2021 by BaerbelW
On Tuesday, April 27 2021 I participated in session EOS7.10 at the virtual General Assembly of the Eurogeosciences Union (EGU) titled Science to Action: Communication of Science and strategies to fight misinformation - Practice, Research and Reflection This session was convened by Sam Illingworth, Heidi Roop, Mathew Stiller-Reeve, Kristin Trimm, Laure Fallou, Irina Dallo, Michèle Marti and Femke Mulder. The session - run at both AGU and EGU - encouraged critical reflection on science communication best practices and provided an opportunity for the community of science communicators and researchers to share best practices and experiences with evaluation and research in this field. The session also explored the way efficient communication strategies can help prevent, fight and debunk misinformation. Case studies, comparisons between different hazards and risks as well as best practices to fight misinformation at all stages of the risk cycle were explored.

"CO2 is plant food." No.
Despite propaganda to the contrary CO2 isn't "plant food," any more than sugar is "food" for us humans. CO2 is a metabolic requirement for plants, an input among many to a complex metabolism evolved and tuned to work with what it "knows." Plants are adapted for less than 400 ppm of CO2 and when this level is exceeded strange effects can happen in terms of health and function of plants themselves. But it turns out that unexpected outcomes are even larger than we thought. In CO2 physiological effect can cause rainfall decrease as strong as large-scale deforestation in the Amazon,

vEGU21 - EOS3.2 - Climate Literacy
Posted on 28 April 2021 by BaerbelW
A somewhat rocky start
On Monday, April 26 the 2nd week of vEGU21 - the all virtual General Assembly of the Eurogeosciences Union (EGU) - started into the scientific programs which were all held in the vPico format. The initial week had seen a much more relaxed schedule with mostly Great Debates, Union Symposia and Short Courses on the agenda. So, this start of the 2nd week saw a much increased pace, activities and attendees all rushing into the many online sessions running in parallel. So it was little wonder that many vPICO-sessions experienced some technical issues and that the conference servers were taxed to the max and sometimes even crashed under the load or were not reachable for a few minutes.
To get an idea of how the sessions worked - or were supposed to work - I had joined the Geoethics session EOS4.2 which turned out to be one of those affected by these issues. The conveners Silvia Peppoloni and Giuseppe Di Capua did an amazing job to nonetheless get through all the presentations in the allocated time but unfortunately the text-chat break outs didn't come to pass. As other sessions had comparable issues, a decision was made by the organizers to switch from Big Blue Button to Zoom as the session tool and during a longer than planned lunch-break all afternoon sessions received a Zoom-ID and could get underway an hour later than originally planned. The EGU Today Newsletter for Tuesday, April 27 has some more information about the rocky start and recovery from that.

Skeptical about a defense of science?
Posted on 26 April 2021 by doug_bostrom
On April 21 US House Representative Frank Lucas (3rd District, Oklahoma) transmitted an urgent inquiry to the White House concerning the abrupt reassignment of Dr. Betsy Weatherhead, out of her position as head of the Fifth United States Climate Assessment and into another role at the United States Geological Survey. Rep. Lucas expressed dismay with this decision while asking for background information, writing: "While Administrations are free to hire their own political appointees, penalizing and removing civil servants represents disturbing political interference in the federal scientific enterprise." He went on to express that it was "difficult to think of a more clear example of political interference and bias than this leadership change."
Representative Lucas' claims and complaints are puzzling in light of his personal context of career, experience and habits of attention.
Representative Lucas assumed office in 2003, and as with the rest of us has just emerged from a period of interference in the scientific activities conducted by the federal government unequaled in modern history and arguably during any period since congress and the executive branch first began integration of science into the apparatus of national government. This meddling significantly degraded scientific capacities and capabilities intended to help improve the lives of US citizens. The previous administration's tampering was breathtaking in its sweeping scope and brazen nature, widely publicized, impossible to ignore. Mr. Lucas was a member of the House Committee on Science, Space and Technology while this maelstrom swept over the federal scientific enterprise, on watch.
By his office, by his party affiliation, and by his deep experience with affairs and practices of the federal government Mr. Lucas was ideally positioned to monitor the rough handling of scientific integrity during a period of exceptionally transgressive actions. Thanks to the efforts of previous administrations, protection of scientific integrity within federal departments and agencies is a formally recognized, codified priority throughout the federal government. The performance of the government in respect of this is monitored both within the government and by independent organizations. Representative Lucas has enjoyed continuous, easy access to multiple channels of surveillance of scientific integrity prior to April 21.

Energy exchange vs. Energy change.
Elevator Statement
Energy change represents a change of the total global energy. Energy exchange represents an exchange of energy between two parts of the Earth’s systems, without necessarily increasing the total energy.
A seesaw exchanges the potential energy of Person A on one side of the seesaw to Person B on the other side of the seesaw. As Person A falls, they lose potential energy, causing Person B to rise, gaining the potential energy lost by Person A. In this process there is no change in the total energy of Person A+B: energy is merely exchanged between two people (there is a small amount of energy lost due to friction in the center pivot, requiring each person to push off the ground a small amount).
Climate Science
The oceans and the atmosphere represent two objects that also exchange energy, engaging in their own SeaSaw, where in some years the oceans lose energy to the atmosphere, and in other years the atmosphere loses energy back to the oceans. Just as two people using a seesaw merely exchange potential energy back and forth, without changing their total potential energy, so too, during energy SeaSaw cycles the oceans and atmosphere exchange energy. Although the long-term trend is that global warming causes both the oceans and the atmosphere to gain energy, because the energy exchanged between the oceans and the atmosphere can be up to 10 times as much as the energy gained by the atmosphere during a given year, it is usually difficult to estimate the amount of global warming from the temperature change of the atmosphere from one year to the next. To estimate the magnitude of global warming typically requires looking at atmospheric temperature trends from one decade to the next, or more commonly, by using a 10-year moving average. Try out the SkS Temperature Trend Calculator to see how the averaging period affects the temperature trend line.

Near doubling of age of oldest coherent ice core on tap?
Studies of paleoclimate help us to understand our own recent creation of accidental rapid climate change and what we may expect from our blunder. Among many other sources of paleoclimate data, ice cores stand out for their near "tape recorder" fidelity in recording various features of climate of the past and - even better - some direct information about what may have been shaping climate at any given time during ice core coverage.
The very oldest ice recovered from "deep storage" in Antarctica (and anywhere) so far dates back about 2.7 million years. There is certainly useful information to be had from these samples but as a tape recording goes they're the equivalent of a reel that has been sliced into segments of instants of time then scrambled, with most segments gone missing. That's because their preservation was the result of happenstance as ice passing over particular forms of topography encountered "turbulence," with some fragments of very old layers pushed higher toward the surface so that even while parent layers were subsequently lost, these scattered parts remained available. Beyond this fluky preservation mechanism leaving a lot of gaps, it's a non-trivial job to identify the age of such chunks and unscramble their place in chronology.
The oldest coherent and most-like-a-tape-recording ice core we have in hand spans a bit more than 800,000 years into the past. This is an impressive achievement and has proven valuable for our understanding of climate behavior and drivers over "deep time." But of course it leaves us hungry for more, according with our species' insatiable curiosity.
Now a substantial team of researchers led by David Lilien have published a paper that may well mark exactly "X" on the map of where to drill in order to nearly double our coherent ice core record. Yet again the spot lies in Antarctica. Using newly available radar equipment and an abundance of brain power, the group have identified and characterized an apparently intact sequence of ice layers extending to 1.5 million years ago. This is an important, significant discovery. These results suggest it won't be long before we see cores hauled up; the prospects and demand for new data are compelling to "drill, baby, drill." When those cores emerge, our insight into climate behavior will be projected backward to nearly double what we could before see.

Why scientists shouldn't heed calls to 'stay in our lane'
Posted on 20 April 2021 by Ben Santer
This is a re-post from Yale Climate Connections
It’s hard to lose a long-term friendship. That happened to me last year. My friendship did not survive my unwillingness to “stay in my lane.”
I met my friend – let’s call him T – while I was a student at Cornwall School in Dortmund. Back in 1966, our family moved from suburban Maryland to Dortmund in Germany. My parents had to decide whether to enroll me in a German school or a British Army school. Because I spoke no German at the time, they chose the British Army school.
I was the only American in a school of over 400 British students. It was tough going. I spoke with a different accent. My parents were not in the military. My parents did not live on the British base in Dortmund. I did not know how to play soccer, rugby, or cricket. I was “the Yank.” I stuck out like the proverbial sore thumb. Finding friends was essential to a survival strategy.
T was one of my friends. He was fascinated by history, and a never-ending source of information about military strategy, the rise and fall of the Roman Empire, and obscure Greek philosophers. We shared interests in literature and language. And T was always funny, with a goofy and endearing grin.
After graduating from Cornwall, I remained in contact with T – we did not let our friendship fade into an insubstantial memory. We wrote each other letters and holiday cards. T’s communications continued to explore rich veins of history and philosophy. They were always a joy to read.
In 1999, while attending a scientific conference in the U.K., I met T again. It was a trip down memory lane – an opportunity to reminisce about our time at Cornwall School, catch up on what had become of old classmates, and reflect on where we were in our lives.
A few years later, T invited me to be best man at his wedding. I felt deeply honored to receive his kind invitation. I had never been “best man” at a wedding. I bought a nice suit for the occasion, flew over from California to London, and caught a train to Manchester for the event. “It was a good do,” as the Brits might say. I gave T and his wife a blown-glass vase I had brought from California, painted with a motif of California poppies. “Always keep your marriage fresh,” I wrote in a card to the happy couple. “Always keep fresh flowers in the vase.”
And then Trump happened.
'Disinformation ecosystem' - in broader context beyond climate
Posted on 19 April 2021 by greenman3610
This is a re-post from Yale Climate Connections by Peter Sinclair
This edition of Yale Climate Connections’ “This Is Not Cool” video explores the “disinformation ecosystem” in and beyond the issue of global climate change.
“How did we get here?” independent videographer Peter Sinclair asks rhetorically at the start of the video. He points to Americans seeming to routinely disagree not solely on priorities, but also on “a fundamental universe of facts.”
The video explores four decades of rhetoric from fossil fuel interests and political activists “undermining belief in science and fact.” It probes similar public relations efforts over the years involving health effects of smoking and “anti-vaccine theories.” At one point the video displays a poignant clip from the once-popular weekly “Mary Tyler Moore” TV program involving cigarettes. The video also illustrates how some TV personalities have routinely dismissed climate change science as a “hoax” or “scam” and pointing to scientists’ allegedly helped to create a “phony crisis.”
The video includes interviews with several different reporters, one, John Schwartz from the New York Times, dismissing efforts by some to “create their own reality.” Another points out that comparable efforts were under way well before President Trump took office, and still another points to social media algorithms fostering the spread of misinformation.
Schwartz refers to a continued desire by some to “pick and choose information” as they would select food from a smorgasbord, allowing individuals to “choose your own reality.”

vEGU21 - Gather online - Prolog
Posted on 15 April 2021 by BaerbelW
Just like last year, this year's General Assembly of the European Geosciences Union (EGU) will happen virtually instead of in person in Vienna. Contrary to last year, the organizers decided early on to hold their conference online and planned for it accordingly (quite a difference to last year's scramble where they switched from an on-premise to an all-online conference within just about six or seven weeks!).
As a consequence, this year's "vEGU21: Gather Online", will not be free of charge as it was last year and conference activities will only be available for registered participants from now until May 31. Afterwards, any presentations uploaded under a creative commons license to the website will become open access and will be available on EGUSphere.
vPICO session format
All scientific sessions at vEGU21 will be run in the new virtual PICO (vPICO) format where each 1.5-hour-long vPICO session will feature approximately 20 abstracts and be divided into two parts: an overview and chats. Each session will have an introductory round of live 2-minute talks (each based on a single slide) which will be presented in a central video chat moderated by the session conveners. After all 2-minute talks of a time block have been finished, each presentation will have its own live text chat, where participants can post questions to the abstract authors to stimulate further discussion.
I'll know pretty soon how well this will work as John Cook and I have abstracts in two sessions, one each on Monday (in EOS3.2) and Tuesday afternoon (in EOS7.10) which I'll be presenting. EGU does have a "one abstract per presenting author rule" but our abstracts are both in Education and Outreach sessions (EOS) where two abstracts are luckily allowed. Which is why we were able to submit abstracts to two different sessions.
