Delighted to officially join Carnegie Ecology today, just behind recent hires Elena Litchman @lorenzorosa1992 and Emily Zakem! The opportunity to learn from them, Ken Caldeira, colleagues not on Twitter, Stanford Woods Institute, @CalTechESE, etc., is so exciting! carnegiescience.edu/news/new-facul…

Audrey Odwuor is a UCI ESS Ph.D. student who studies particles in fire smoke with Profs James Randerson (📸) and Claudia Czimczik. Here she is at the Blodgett Forest Research Station Berkeley Forests as part of SPARx (Smart Practices and Architectures for Rx fire in California).

📢New paper alert!📢 Excited for our new paper published in AGU (American Geophysical Union)'s Water Resources Research on identifying hotspots of seasonal precipitation predictability from limited time series observations. (1/4) agupubs.onlinelibrary.wiley.com/doi/full/10.10…

"California wildfires caused by humans are more dangerous than fires sparked by lightning." Reporting hot off the press from Corinne Purtill Corinne Purtill Los Angeles Times on new UCI ESS research from Prof. James Randerson, Yₐₙ₉ Cₕₑₙ and others.latimes.com/science/story/…

Check out our new paper in AGU Advances! We used satellite data and machine learning to map annual disturbances and vegetation in California from 1985-2021 to see how fires are reshaping forests. Available now for the low low price of $0 open access: doi.org/10.1029/2021AV… 1/n

Forests are key in natural climate solutions but are threatened by disturbances like fire, making their viability uncertain. Since 1985, forest growth in CA can't keep up with recent extreme wildfire seasons, resulting in a net loss of tree cover by 6.7%. 2/n

Tree cover dynamics (dark green line, top panel) varied widely geographically. Northern forests were impacted by harvest and recent fires, but recovered when it rained in the 90s. Rapidly warming southern forests might be losing their ability to recover from disturbance. 3/n

Tree losses were concentrated in the hottest parts of the state. As summer temperatures continue to climb, even more of California's forests will be threatened by wildfire and climate stress. 4/n

All about our recent AGU Advances article (bit.ly/3yWsaCK), featuring yours truly and James Randerson! Thanks to Center for Ecosystem Climate Solutions @LucasVanWykJoel UCI ESS for the support.

How much does evaporation affect temperature variations during the day?  That’s what we looked at in a paper just published online in the Journal of Climate.  Annu Panwar American Meteorological Society Max Planck Institute for Biogeochemistry earthsystem.org/2022/07/24/202…

I made this some years ago, but it is still kind of fun. This is a map of 45,000 current & historical weather stations that have reported temperature data. There are no political or geographic markers on the map, but it is still easy to identify land masses and some countries.

A new paper led by Shane Coffield shows how Landsat-derived carbon and disturbance products can be used to evaluate the effectiveness of forest carbon offset projects!

Interested in why Amazonia will become a drought hotspot in the future? Our new Nature Water paper found at least 40% of rainfall decline can be attributed to CO2 physiology and deforestation in SSP scenarios. Free read-only rdcu.be/dkR4Z, nature.com/articles/s4422…

In three weeks (7-9 November) the first BBURNED virtual workshop #BBURNED_FEW reviewing the current status and new developments of fire emission estimation will take place. More information, agenda and registration details can be found at www2.acom.ucar.edu/bburned/fire-e…

As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023. We are afraid of the uncharted territory that we have now

My warm & friendly academic home department UCI ESS UC Irvine School of Physical Sciences UC Irvine is searching for a new atmospheric science assistant professor. We'll start reviewing applications in the coming weeks and it's not too late to apply. Please spread the word. recruit.ap.uci.edu/JPF08736

Very excited to see Jinhyuk Kim's new paper on the contribution of fire to trends in boreal photosynthesis published today in GCB. Jon Wang 🏳️‍🌈🇺🇲🛰 @jin_ekim
