Gas underestimated and we’ll get 2.3 C of heating with what we’ve emitted thus far, but we can control the speed

More Than Two Degrees of Climate Warming Is Already Locked In, New Study in Nature Climate Change Finds, by Olivia Rosane Jan. 06, 2021 Researchers estimate that a likely total of 2.3 degrees Celsius of warming is now locked in. DuKai photographer / Getty Images Existing greenhouse gases will eventually push the climate into more than two degrees of warming, according to a study published …

Faster melting, hotter temperatures predicted in new climate models

15 December 2020, Carbon Brief, New climate models suggest faster melting of the Greenland Ice Sheet AYESHA TANDON Greenland’s vast ice sheet could melt faster than previously thought over the 21st century, according to a new study. The Greenland ice sheet is the second largest mass of ice on Earth, holding enough water to raise global sea levels by 7.2 metres. …

1.5°C above baseline is now the prescribed upper limit to global warming. Global temps for first 6 months of 2020 registered 1.3°C above baseline.

Global temperature for the first six months of 2020 registered 1.3°C above baseline, a number that has new significance ever since the IPCC Special Report/2018 about the risks of exceeding 1.5°C. NOVEMBER 20, 2020, https://www.counterpunch.org/2020/11/20/expert-ipcc-reviewer-speaks-out/ Expert IPCC Reviewer Speaks Out BY ROBERT HUNZIKER Expert IPCC Reviewer Speaks Out Roger Hallam, co-founder of Extinction Rebellion/XR recently interviewed Peter Carter, M.D., who has …

Colorado and California temperature and wildfire extremes

Colorado has warmed 2 degrees F on average in the last 30 years. Colorado’s recent average summer temperatures are even higher than the extreme heat of the 1930s Dust Bowl. Peak runoff has been coming 1 to 4 weeks earlier. Warming temperatures and drier soils increase the likelihood of larger wildfires. Colorado broke its average-temperature record for August, when the …

Nearly all of Colorado is under some drought status – 20 years into megadrought in the West

Also see: https://blogs.ei.columbia.edu/2020/04/16/climate-driven-megadrought-emerging-western-u-s/ – April 20th, 2020 The Colorado Sun | evan@coloradosun.com Colorado currently is one of the drier parts of the country, and although conditions have improved in recent weeks, the long-term outlook for the state is relatively grim.  Much of Colorado continues to suffer through extreme drought, and nearly all of the state is experiencing drought, according to the …

It’s Not as Simple as Rebellion

By Tim DeChristopher, originally published by YES! magazine July 2, 2020 Ed. note: This piece was posted to YES! Magazine on May 11, 2020. Over the past two years, Extinction Rebellion (XR) emerged into the climate movement with explosive energy. Thousands of people in Europe and the United States mobilized to engage in civil disobedience to demand that our political leaders take …

First ever temperatures over 100 F in Arctic, occurring 80 years early for what is projected if current emissions trends continue

What’s perhaps even more impressive is that this relative warmth has persisted since December, with average temperatures in western Siberia 10 degrees Fahrenheit above normal — doubling the previous departure from average in 2016. The average heat across Russia from January to May is so remarkable that it matches what’s projected to be normal by the year 2100 if current …

New climate modeling shows that worst-case scenarios do not go far enough

Modelling suggests climate is considerably more sensitive to carbon emissions than thought, by Jonathan Watts 13 Jun 2020, Guardian Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said. Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts …

The heat waves that powered the Dust Bowl are now more than twice as likely to happen again MICHAEL D’ESTRIES May 27, 2020 A dust storm approaches Stratford, Texas, in 1935. (Photo: NOAA George E. Marsh Album [public domain]/Wikimedia Commons) They were called “black blizzards” and “black rollers,” towering billows of dust rising thousands of feet high that became ominous symbols of …

Climate justice and one of the most important climate change articles: climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop

The severity of damaging human-induced climate change depends not only on the magnitude of the change but also on the potential for irreversibility. This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop. Following cessation of emissions, removal of atmospheric carbon dioxide decreases radiative …
