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 …

Tropical Storms Are Getting More Intense: nearly four decades of satellite data from storms around the world, the likelihood of a storm reaching Category 3 or above, with sustained winds above 110 miles per hour, increased 8 percent per decade

 Jordan Davidson May. 19, 2020 Climate Home News The devastation caused by hurricanes in the Bahamas, Puerto Rico, North Carolina and Houston over the last few years is a direct effect of the climate crisis, which is making tropical storms stronger and wetter, according to a new study from the University of Wisconsin and the National Oceanic and Atmospheric Administration (NOAA), as CNN reported. The study looked …

The Struggle to Keep Justice Central within Extinction Rebellion US

By Margaret Flowers and Kevin Zeese, Clearing the FOG. March 9, 2020 | PODCAST The Extinction Rebellion is a nonviolent direct action campaign that started in the United Kingdom in the Fall of 2018 to push governments to declare a climate crisis and to take action to rapidly cut net carbon emissions. It quickly spread to more than 50 countries including the …

Arctic Permafrost Is Melting so Fast, It’s Gouging Holes in the Landscape: New research finds carbon emissions estimates should be doubled

 Jordan Davidson Feb. 04, 2020, SCIENCE Permafrost is thawing so fast, in can turn a forest into a lake in the course of one month. Flickr / CC BY-NC 2.0 Current estimates of carbon emissions from melting Arctic permafrost rely on a model of a gradual melt. New research has found abrupt thawing of permafrost which means carbon emissions estimates should be doubled. The rate at …
