Most climate models do not yet account for a new University of California, Riverside discovery: methane traps a great deal of heat in Earth’s atmosphere, but also creates cooling clouds that offset 30% of the heat.  - In addition to absorbing longwave energy, it turns out methane also absorbs incoming energy from the sun, known as shortwave energy. “This should warm the planet,” said Allen, who led the research project. “But counterintuitively, the shortwave absorption encourages changes in clouds that have a slight cooling effect.”

By SETH BORENSTEIN The Associated Press: Climate change is making major league sluggers into even hotter hitters, sending an extra 50 or so home runs a year over the fences, a new study found. Hotter, thinner air that allows balls to fly farther contributed a tiny bit to a surge in home runs since 2010, according to a statistical analysis by Dartmouth College scientists published in Friday’s Bulletin of the American Meteorological Society. They analyzed 100,000 major league games and more than 200,000 balls put into play in the last few years along with weather conditions, stadiums and other factors.  “Global warming is juicing home runs in Major League Baseball,” said study co-author Justin Mankin, a Dartmouth climate scientist. It’s basic physics. ... Both Nathan and the Dartmouth team found a 1% increase in home run likelihood with every degree the air warms (1.8% with each degree Celsius). Total yearly average of warming-aided homers is only 1% of all home runs hit, the Dartmouth researchers calculated. ... The statistical analysis found no significant heat-aided homers at Tampa’s Tropicana Field, the only full-time domed stadium in Major League Baseball. ...

Mankin called what’s happening “a fingerprint of climate change on our recreation.” Callahan said what’s been seen so far is nothing compared to projections of hundreds of extra homers in the future. In the worst-case warming trajectory – which some scientists say the world is no longer on based on recent emissions – there would be about 192 warming-aided homers a year by 2050 and around 467 hot home runs by the year 2100.

Curry: " The IPCC Reports have become 'bumper sticker'  climate science – making a political statement while using the overall reputation of science to give authority to a politically manufactured consensus." ... "The IPCC has strayed far from its chartered role of assessing the scientific literature in support of policy making. The entire framing of the IPCC Reports is now around the mitigation of climate change through emissions reductions. Not only has the IPCC increasingly taken on a stance of explicit political advocacy, but it is misleading policy makers by its continued emphasis on extreme climate outcomes driven by the implausible extreme emissions scenarios." ... 

"The most important finding of the past 5 years is that the extreme emissions scenarios RCP8.5 and SSP5-8.5, commonly referred to as 'business-as-usual' scenarios, are now widely recognized as implausible. These extreme scenarios have been dropped by UN Conference of the Parties to the UN Climate Agreement.  However, the new Synthesis Report continues to emphasize these extreme scenarios, while this important finding is buried in a footnote: “Very high emission scenarios have become less likely but cannot be ruled out.”

Dr. Roger Pielke Jr. "Everything you find in this thread. Everything -- is consistent with what has been reported in the IPCC & found in official data and the peer-reviewed literature." 

MICHAEL BASTASCH: Variations of the words “equity” and “inequity” appear 31 times in the 36-page (summary) document. Variations of “inclusive” and “inclusion” appear 17 times. The document even mentions “colonialism” and repeatedly refers to climate and social “justice” for “marginalized” groups. ... The UN report also contains an entire section titled “Equity and Inclusion,” which states “[e]quity remains a central element in the UN climate regime.” The report goes on to state that “[r]edistributive policies … that shield the poor and vulnerable, social safety nets, equity, inclusion and just transitions, at all scales can enable deeper societal ambitions and resolve trade-offs with sustainable development goals.” ... The report’s accompanying press release is quite explicit about its goal: “Taking the right action now could result in the transformational change essential for a sustainable, equitable world.” ... 

The release goes on to quote one of the report’s authors, who says: “Climate justice is crucial because those who have contributed least to climate change are being disproportionately affected.”
