The new Global Fire Emissions Database (GFED5, 2002β2022) shows that at the global scale 1) by far, most area burned are grasslands; 2) area burned is declining; & 3) fuel consumption is increasing: ie, fires are increasing in forests & encroached grasslands.

Clouds darkening over NOAA research. We are slated for elimination in next years budget. Astonishing loss to the nation and the world if it happens.
BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency.
Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

CSL is a NOAA lab that has been foundational in atmospheric chemistry & air quality science. They are now losing young scientists that are among the best/brightest of the next generation. This degrades not just CSL but our ability to track pollution & protect health.
