Do you have a link to those reports? Most of my recent sauce has been news articles about the reef dying. Coral bleaching itself underlies a different concern with CO2 emissions, the acidification of our oceans. Water naturally absorbs CO2 and becomes more acidic as time passes, and it's going at a rate where natural marine life aren't all coping/adjusting within the rapid timeframe. This is undeniable and not up to interpretation to the point where it's glossed over and ignored by both alarmists and skeptics. I guess people are more drawn to conflict and drama over ambiguous issues...given that they are issues we can not individually solve on our own.
I think this was what I saw. cannot vouch for it: https://www.aims.gov.au/reef-monitoring/gbr-condition-summary-2020-2021
Quotes from AR6 "Summary for Policymakers" Report: Evidence of observed changes in extremes such as heatwaves, heavy precipitation, droughts, and tropical cyclones, and, in particular, their attribution to human influence, has strengthened since AR5. A.3.1 It is virtually certain that hot extremes (including heatwaves) have become more frequent and more intense across most land regions since the 1950s, while cold extremes (including cold waves) have become less frequent and less severe, with high confidence that human-induced climate change is the main driver of these changes. Some recent hot extremes observed over the past decade would have been extremely unlikely to occur without human influence on the climate system. Marine heatwaves have approximately doubled in frequency since the 1980s (high confidence), and human influence has very likely contributed to most of them since at least 2006. A.3.2 The frequency and intensity of heavy precipitation events have increased since the 1950s over most land area for which observational data are sufficient for trend analysis (high confidence), and human-induced climate change is likely the main driver. Human-induced climate change has contributed to increases in agricultural and ecological droughts in some regions due to increased land evapotranspiration16 (medium confidence). A.3.3 Decreases in global land monsoon precipitation from the 1950s to the 1980s are partly attributed to human-caused Northern Hemisphere aerosol emissions, but increases since then have resulted from rising GHG concentrations and decadal to multi-decadal internal variability (medium confidence). Over South Asia, East Asia and West Africa increases in monsoon precipitation due to warming from GHG emissions were counteracted by decreases in monsoon precipitation due to cooling from human-caused aerosol emissions over the 20th century (high confidence). Increases in West African monsoon precipitation since the 1980s are partly due to the growing influence of GHGs and reductions in the cooling effect of human-caused aerosol emissions over Europe and North America (medium confidence). A.3.4 It is likely that the global proportion of major (Category 3–5) tropical cyclone occurrence has increased over the last four decades, and the latitude where tropical cyclones in the western North Pacific reach their peak intensity has shifted northward; these changes cannot be explained by internal variability alone (medium confidence). There is low confidence in long-term (multi-decadal to centennial) trends in the frequency of all-category tropical cyclones. Event attribution studies and physical understanding indicate that human-induced climate change increases heavy precipitation associated with tropical cyclones (high confidence) but data limitations inhibit clear detection of past trends on the global scale. A.3.5 Human influence has likely increased the chance of compound extreme events18 since the 1950s. This includes increases in the frequency of concurrent heatwaves and droughts on the global scale (high confidence); fire weather in some regions of all inhabited continents (medium confidence); and compound flooding in some locations (medium confidence).

I don't disagree with what he is saying there - but that's a very narrow analysis limited to certain aspects of hurricanes that make landfall - a very small sample size to draw any conclusion from. What we do know is that peak winds of hurricanes not at landfall have increased, and we know hurricanes are far wetter in the past. We also know that the number of extreme events (not just hurricanes) have increased dramatically in the past 20 years.
Is There a Nuclear Option for Stopping Climate Change? https://www.nytimes.com/2021/08/26/opinion/climate-change-nuclear.html?smid=url-share excerpt: Humanity’s failure to avert the crisis of a warming climate is sometimes framed as a grand technological problem: For centuries, countries relied on fossil fuels to industrialize their economies and generate wealth, and it was only in recent years that alternative ways of powering a society, like solar and wind energy, became viable. But when it comes to electricity, at least, that story isn’t true. Today, the United States gets 60 percent of its electricity from fossil fuels and just 20 percent from renewables. The final 20 percent comes from nuclear power, a technology that has existed since the 1950s, produces no carbon dioxide and has killed far fewer people than fossil fuels. Decarbonizing the electric grid is certainly not the only challenge climate change poses, but it is the central one. And the Biden administration has said the United States needs to meet it by 2035. Should nuclear power be playing a bigger role in the transition? Here’s what people are saying. The case for going nuclear Its proponents often point out that nuclear power is responsible for the fastest decarbonization effort in history. In the 1970s, France embarked on a sweeping, centrally planned expansion of its nuclear power industry to break its dependence on foreign oil. Over the next decade, it managed to expand its economy even as it cut its emissions at a rate that no other country has achieved since. Today, France derives 70 percent of its electricity from nuclear power. Why shouldn’t the United States follow suit? “A rapid increase in nuclear energy would slash emissions from the power sector, as the French example makes clear,” The Atlantic’s Robinson Meyer wrote in 2019. “Even today, France’s carbon density — its carbon emissions per capita — ranks well below that of Germany, the United Kingdom and the United States.” While renewable energy has made enormous strides in recent years, nuclear power still has distinct advantages. Solar and wind farms, for example, take up much more space than nuclear plants, and they provide power only as the weather allows. In part for that reason, several recent studies have found that utilities could achieve 80 percent zero-carbon electricity by 2030 using today’s renewable energy technology, but cleaning up the last 20 percent will prove more difficult. There are several proposed ways of solving renewable energy’s storage problem — including huge battery arrays and hydrogen fuel — but those technologies aren’t yet up to the task, my colleague Brad Plumer wrote last month. From a public health perspective, nuclear power is also much safer than fossil fuels, Joshua S. Goldstein, Staffan A. Qvist and Steven Pinker argued in The Times in 2019. According to one study published this year, air pollution from fossil fuels killed a staggering 8.7 million people in 2018. By contrast, Goldstein, Qvist and Pinker noted that in 60 years of nuclear power, only three accidents have raised public alarm, and just one — Chernobyl — directly caused any deaths. What about nuclear waste, which can remain radioactive for tens of thousands of years? Compared with climate change, it’s a much easier environmental problem to solve, they wrote. More than 90 percent of spent fuel can be recycled, and that which can’t could be entombed in repositories deep underground, as is done in Finland. In 1987, Congress settled on plans to build a national nuclear waste repository in Nevada, but local, state and federal opposition have thwarted the project for decades. As a result, America’s nuclear plants keep their waste on site in steel and concrete casks that were not intended for permanent storage. But it doesn’t have to be this way. “If the American public and politicians can face real threats and overcome unfounded fears,” Goldstein, Qvist and Pinker argued, “we can solve humanity’s most pressing challenge and leave our grandchildren a bright future of climate stability and abundant energy.” more at the link
Not to derail the thread, but that movie jumped the shark several times. In fact, it should have been Fonzie in his black leather jacket extreme-surfing the glacier.
U.S. begins detaining solar panel imports over concerns about forced labor in China Detentions follow import ban enacted by Customs and Border Protection on solar products containing materials from the Chinese company Hoshine https://www.washingtonpost.com/business/2021/08/27/customs-detains-chinese-solar-panels/ excerpt U.S. officials have begun blocking the import of solar panels they believe could be the product of forced labor in China, implementing a recent ban that could slow construction of solar-energy projects throughout the country. Industry executives and analysts said that solar panels from at least three Chinese companies have been targeted in recent weeks, and a Customs and Border Protection spokesman confirmed by email that the agency has “made a number of detentions” of products under the import ban. CBP imposed the ban in June on Hoshine Silicon, which produces raw materials used in solar panels. The agency said it had information “reasonably indicating” that Hoshine, which operates plants in China’s Xinjiang region, uses forced labor, a finding that triggered the ban because U.S. law prohibits the import of goods made by coerced workers. more at the link
According to weather reports Hurricane Ida will strengthen very fast due to extremely warm surface water in the Gulf. As warm as 90 degrees F.
500 years event. First two flash flood emergencies in NY/NJ history. @Os Trigonum, @Sweet Lou 4 2 are you from the area? How is it? https://www.mediaite.com/news/stunning-images-emerge-of-catastrophic-and-deadly-flooding-in-nyc/
I was in the area - out to dinner and driving home through a torrential downpour - some of the heaviest rain I have ever seen. And went on for hours. Streets were flooding and it was sketchy
good summary by Curry of the "15 minute" elevator speech to describe what might be called the climate pragmatism position https://judithcurry.com/2021/09/03/15-minutes/
Judith Curry.... Pielke Jr..... occupy an interesting climate niche. She just laid out a bunch of vague talking points in her "climate pragmatism position".... while questioning the recent IPCC report.
