The new Global Fire Emissions Database (GFED5, 2002–2022) 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. www.nature.com/articles/s41... 🧪🌍🔥🌳🌐

Some memes are relatable they aren’t even like funny, just actively insulting.

A letter in Science about the importance of NASA Earth Science from several members of the recently-dissolved NASA Earth Science Advisory Committee. Out today online and in the 7/24 issue. www.science.org/doi/10.1126/...

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.

Sometimes you *should* meet your (science) heroes. Stan was a giant of chemical kinetics and just a gem of a person. We will miss him.

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. csl.noaa.gov

These were *volunteer* science advisory committees that provided NASA with independent perspective and community guidance ... explain to me how eliminating these is a way to "reduce waste and abuse"

The #standupforscience2025 rallies will be held in DC and around the U.S. NEXT FRIDAY. Please sign up to attend at standupforscience2025.org To effectively push back the attacks on science happening now, it is so critical to show mass support for science by gathering together in the streets!

Do you want a big overview of NSF, explaining things like the fact that 24% of all federally funded academic fundamental research comes from NSF? And that 94% of its budget goes out the door in grants/awards? Here you go. nsf-gov-resources.nsf.gov/files/Factsh...

These are the people who monitor and publish Lake Superior's conditions every day. Minnesotans along the North Shore rely on NOAA to know whether or not it’s safe to go out on the water. These agencies and their staff do real work that keeps us safe, it just goes unnoticed - until they’re gone.

🧪 The Water Resources Center wrc.umn.edu at the University of Minnesota is looking for a new director. Come be my colleague! Application info here: hr.myu.umn.edu/jobs/ext/366...

Along with being the largest gathering of Earth scientists in the world, the AGU meeting may also be the largest concentration of backpack-wearing adults in the world (self included) #AGU24

Congratulations @mvermeuel.bsky.social on receiving the #AGU24 Holton Award!

@envchemjen.bsky.social is now on bluesky!! 👋 Give her a follow!

The “What’s Next for Science” slogan for this meeting feels a little on the nose under the circumstances

Excited for a full week of sciencing with 25,000 of my best friends #AGU24

Lots of transitions in academia:

🧪 2 new group papers out this week: 1/2) Josh Shutter links satellite measurements of isoprene and formaldehyde to diagnose multiyear atmospheric OH changes over forests: including a long-term decrease in Southeast US + interannual variability in tropical regions due to ENSO doi.org/10.1126/scia...

"experts have been trying to reconcile the precise time, as set by atomic clocks, w/ somewhat unreliable speed at which Earth spins. Since 1972, authorities have added 27 leap seconds...Recently however, Earth's spin has sped up suggesting we might need to remove a sec from UTC" Negative leap second

Some professional news…

I recently made a comic complaining that NASA refuses to listen to my good ideas for improving the Solar System (xkcd.com/2750). To my delight, NASA’s Science Mission Directorate has sent me an actual expert panel evaluation of my “flatten the planets” proposal! Sadly, they decided not to fund it.

I feel like this feedback I got from my 10th grade science teacher stands the test of time
