wolf at the door. Rather than extrapolating cumulative ice loss, a peer-reviewed study that uses fine-scale ice sheet model with uncertainty quantification indicates the Greenland Ice Sheet could disappear entirely in 1,000 years. This is only true if the rate of annual ice loss were to remain the same as todays rate for a long time. Intergovernmental Panel on Climate Change Sixth Assessment Report Working Group I Chapter 11, https://www.cell.com/one-earth/fulltext/S2590-3322(20)30247-5, https://www.nature.com/articles/nclimate2657, Climate Change 2021: The Physical Science Basis, Tropical cyclones and climate change assessment: Part I, Detection and attribution, Climate change is probably increasing the intensity of tropical cyclones. if you look at the projections of whats going to happen with the global Greenhouse gas emissions are causing all of this. I found great satisfaction in these roles, helping to define and catalyze actions that would reduce carbon dioxide emissions, the agreed-upon imperative that would save the planet.. Spatial and temporal distribution of mass loss from the Greenland Ice Sheet since AD 1900, Global Increase in Major Tropical Cyclone Exceedance Probability over the Past Four Decades, Clouds, circulation and climate sensitivity, Low-Cloud Feedbacks from Cloud-Controlling Factors: A Review, Insights into low-latitude cloud feedbacks from high-resolution models, External Influences on Modeled and Observed Cloud Trends, Evidence for climate change in the satellite cloud record, Koonins statements may lead you to believe that predictions of future warming are built on a house of cards, with everything resting on poorly-simulated clouds. But doubts began in late 2013 when I was asked by the American Physical Society to lead an update of its public statement on climate. Research shows the opposite: Knutson et al (2019) found that tropical cyclone activity had changed over the last several decades, and that human-caused climate change was likely playing a role in these changes[3]. Phrases like climate emergency, climate crisis and climate disaster are now routinely bandied about to support sweeping policy proposals to fight climate change with government interventions and subsidies. Instead there are large swings in the annual ice loss and it is no larger today than it was in the 1930s, when human influences were much smaller. to roughly eight billion people. It makes for less dramatic warming in the maximums relative to the minimums. Happer became a physicist. There has been an increase in the global proportion of very intense tropical cyclones As a result, most people dont get the whole story. Figure 1 Surface elevation change rates in Greenland during 1900-1983 (a), 1983-2003 (b), and 2003-2010 (c). [Comment from a previous evaluation of a similar claim.]. The latest IPCC report, Yes making climate projections is complex, Yes climate models do make approximations to the laws of physics. This statement is flat out wrong. There is no. As part of that effort, in January 2014 I convened a workshop with a specific objective: to stress test the state of climate science. Opinion This climate change contrarian gives us an important reminder about science in general By Mitch Daniels Contributing columnist October 12, 2021 at 3:30 p.m. EDT Steven Koonin,. It is the case that climate change is worsening many extreme weather events, particularly heatwaves, but this conclusion is founded on a large and growing number of peer-reviewed studies. This video has many major errors and it is difficult to review the veracity of many claims due to the lack of referencing of sources. Next. And But is the world going to end in 10 years or 20 years? Changes in high river levels depend on the region, but the data are sparse so there is low confidence in global changes. [8], The notion that humans are melting Greenland is simplistic, There are large swings in the annual ice loss and it is no larger today than it was in the 1930s, when human influences were much smaller, the annual loss of ice has been decreasing in the past decade even as the globe continues to warm.. Has the argument for taking action on the climate been #climatechange #climateemergency #climatecrisis #scienceandenvironment | 80 comments on LinkedIn Daniel Swain, Climate Scientist, University of California, Los Angeles: As an example of a factually inaccurate statement, Koonin claims that Greenlands ice sheet isnt shrinking any more rapidly today than it was 80 years ago. We are well-aware that uncertainties surrounding clouds affects our ability to know precisely what future warming holds, and focus on predictions from models that better match observations. It appears as though most of the PragerU talking points are the same as those in his book and have not been updated to reflect being repeatedly corrected by the climate science community. the birth of the modern environmental movement in the 1960s, concerns about the November 2, 2017. depends a little bit on where you sit. I believe most of Dr. Koonins talking points have been refuted in several other places, most notably here on climatefeedback.org. nyu-cusp staff: 17 dr. michael holland, chief of staff Professor Koonin was confirmed by the Senate in May 2009 as Undersecretary for Science at the U.S. Department of Energy, serving in that position until November, 2011. There are, however, several key points left out of Koonins cloud argument. Analysis of "Is There Really a Climate Emergency?" Figure 1.2 of the 2018 U.S. National Climate Assessment clearly shows an increase in heat waves in recent decades. Mark Richardson, Research Associate, Colorado State University/NASA JPL: You can also subscribe to my are starting to realize how hard it is to reduce emissions. i-know-my-first-name-is-steven-mike-echols 4/31 Downloaded from odl.it.utsa.edu on October 31, 2022 by guest Unsettled Steven E. Koonin 2021-04-27 "Unsettled is a remarkable bookprobably the best book on climate change for the intelligent laypersonthat achieves the feat of conveying complex information clearly and in depth." Claremont . REVIEWERS OVERALL FEEDBACK 6 . The Wall Street Journal op-ed asserts that it is climate alarmism to claim that Greenlands ice sheet is shrinking ever more rapidly because of human-induced climate change, pointing out a recent headline in the Washington Post Greenland ice sheet on course to lose ice at fastest rate in 12,000 years as an example. Justin Schoof, Professor and Chair, Southern Illinois University: The article picks only the last 10 years, excluding the remaining time series for the context, hence cherry-picking that period and not considering many climatic factors when describing the downward trend. For example, there is myriad evidence that many extreme weather events are intensifying and/or becoming more frequent in most parts of the world (see Intergovernmental Panel on Climate Change Sixth Assessment Report Working Group I Chapter 11, 2021); the extent depends on the region and the type of event, and therefore sweeping generalities (e.g. Below In fact, asClimate Feedback noted in April 2021, the per year average ice loss during 2003-2010 is roughly 2.5 times higher than during 1900-2003. Our model, which performed well in simulating Greenlands history, and stacks up well against other models that took part in a state-of-the-art model comparison effort, suggests that rates this century will, on average, have higher mass loss rates than at present as the Arctic is expected to heat up. This is often referred to as cherry picking.. Political Economy to answer these questions and more. a series of five phases where at first its only among the experts, then [4], Koonin makes a similar claim about flooding, stating that floods have not increased across the globe over more than seventy years. Heres what I discovered: Humans exert a growing, but physically small, warming influence on the climate. Our reviews are crowdsourced directly from a community of scientists with relevant expertise. And even if we Melttemperature nonlinearity and general circulation changes mean that further twenty-first-century warming has important implications for the ice-sheet mass balance, by accelerating the intensity of surface melting and amplifying [Greenland Ice Sheet] GrIS contributions to global sea-level rise.. Among other findings, the study also concluded that intense precipitation events associated with tropical cyclones in the Gulf of Mexico are on the rise. And the good news is that the long-term . change evolved over the past several decades? information from activists painting a very apocalyptic scenario? Arctic Climate impacts Greenland Sea level rise, Published on: 24 Feb 2022 | Editor: Katie Valentine. in Physics from the California Institute of Technology in 1972 and his Ph.D. in Theoretical Physics from MIT in 1975. Koonin is clear that global temperatures are indeed rising, and that some of this rise in temperatures is caused by human activity. 2015[3]. It is the case that climate change is worsening many extreme weather events, particularly heatwaves, but this conclusion is founded on a large and growing number of peer-reviewed studies, says Andrew King, ARC DECRA Fellow and Senior Lecturer in Climate Science at the ARC Centre of Excellence for Climate Extremes at the University of Melbourne. Professor Koonin authored 'Unsettled: What Climate Science Tells Us, What It Doesn't, and Why It Matters' and served as the undersecretary for science in the US Department of Energy under the . Scientist Award (Humboldt Prize) and the Department of Energy's Ernest Orlando Lawrence Award. To position oneself as a rogue truth-teller, bringing to light uncertainties that climate scientists are trying to bury or ignore despite abundant evidence to the contrary is, well, hubris. Help us create a more trustworthy Internet! All you have is emotion. This is not supported by the report he claims to be using. suddenly the public realizes that there is a problem and great enthusiasm for The proportion of major hurricane intensities to all hurricane intensities globally from 1979-2017. Jason Briner, Professor, Department of Geology, University at Buffalo: In the seven years since that workshop, I watched with dismay as the public discussions of climate and energy became increasingly distant from the science. about the future. So at least the best mainstream economic thinking is the economic damages of rising temperatures including tipping points are at the percent level, a nothing burger. We strive to explain whether and why information is or is not consistent with the science and to help readers know which news to trust. Andrew King, Research fellow, University of Melbourne: The proportion of global major hurricanes increased by 25% over the 39-year time period analyzed. He said it started in 2013, when he was asked by the American Physical Society to update the organization's public stance on the changing climate. against deployment except in an extreme situation and with full discussion The globe warmed by 1.1 C since 1900. Increased Flood Exposure Due to Climate Change and Population Growth in the United States. This was regional rather than global, but can be used to make recent changes in the US seem less relevant than they are. Climate Feedback is a non-partisan, non-profit organization dedicated to science education. . Heat waves are getting worse in the United States, especially in recent decades. is an abbreviated transcript of our conversation. His [Steven Koonin's] book is full of important, factual information and insights. its not going to happen at all. Yes, there are human influences, but the climate is complex. Claim: Greenlands ice sheet isnt shrinking any more rapidly today than it was 80 years ago.. Some overviews of how extreme event attribution is conducted, as well as examples of applications to specific events, include: Andrew King, Research fellow, University of Melbourne: The UN report [2] states that heavy rain events have gotten more extreme and more common over a majority of land regions with good observational coverage since 1950, and although some regions dried, the general tendency is therefore higher flash-flood risk (our recent work supports this[7]).
