Did Climate Skeptics Get THIS Right?!
Is global warming just part of Earth’s natural cycle? In this episode of Weathered, we break down why that’s not the full story. From ice ages and Milankovitch cycles to the role of CO2 and fossil fuels, today’s climate change is unlike anything in Earth’s deep past. Learn why the speed of warming m

Just your regular reminder of where global CO2 emissions are tracking compared to scenarios that keep warming to below 1.5C in 2100, with "no or low overshoot" (maximum temperature around 1.6C).

I am one of these NSF postdocs. NSF has frozen everyone’s access to their salaries and research stipends (that were already awarded) with no information about when they might be expected to be unfrozen. It still appears like we are expected to continue doing our work though.
Apparently all the PhD researchers holding prestigious NSF-funded research fellowships are having their salaries withheld until some unspecified time when the leadership figures out how to eliminate any grant funding that doesn’t align with the president’s political ideology.
It’s official: all funding requests made on Tuesday by postdocs for their salaries have been unilaterally rejected by NSF.
