Rapid warming in Arctic and boreal regions may transform forests & tundra from carbon sinks into carbon sources.
Two new papers from @UofUBiology researchers aim to improve how scientists measure biomass across these zones.

Defended! β Kyle Kittelberger studies bird populations to uncover how their biology may change in response to environmental pressures, such as wildfire. Congrats, Kyle!

Fall colors arenβt just beautiful β theyβre biology in action.
As trees prep for winter, leaf pigments shine through, helping them adapt + survive.

"The weak land carbon sink hypothesis" published in @ScienceAdvances today. Drawing upon satellite biomass, we propose increases in the ocean sink and decreases in fossil fuel emissions to close the budget with a net land sink of 0.8 Pg C/y from 2000-2019 science.org/doi/10.1126/sciaβ¦

More CA state forests are vulnerable to wildfire due to climate change, with recent fires so big and intense that forests canβt keep up.

Many thanks to collaborators at @uciess who helped guide this study (@randersonjt @VedBhoot and not-on-Twitter Carl Norlen, Mike Goulden, and Shane Coffield) and @UofUBiology for the support! 7/7
Categorical indices of fire severity (e.g. high vs low) are hard to interpret, and might not capture climate trends. Remote sensing advances are revealing this nuance across ecoregions. Hope this can improve wildfires observation, forest management, and ecosystem models! 6/7
Using a simple model of regional tree loss using burned area, fire severity, and forest exposure, we show that 47% (nearly half!) of observed cumulative tree loss is due to trends in fire severity and forest exposure. Climate warming will exacerbate this. 5/7
Increased forest exposure suggests more dense forests are vulnerable to severe wildfire. In the last decade, wildfire moved in climate space, impacting forests adapted to moister, cooler environments that might have resisted disturbance. 4/7
Average fire severity and forest exposure rose by 30% and 41%, respectively, from 1985-2021. The average tree cover loss per burned area used to be 20%, but recently it has been 34%, on average (+70%!). Increased burned area drives most tree loss, but is not the sole factor! 3/7
We used remotely sensed fractional veg cover and disturbance data to quantify forest exposure (how densely treed were burned areas) and fire severity (relative tree loss) in the average wildfire. Disturbance data: doi.org/10.7910/DVN/CVTNLY Veg data: doi.org/10.7910/DVN/KMBYYM 2/7
Hello there! I'm proud to share a new wildfire paper in ERL - California had recent huge fires but tree loss rose much faster, relatively, than burned area. How much is the per-burned-area impact on tree cover losses rising, and why? Paper: doi.org/10.1088/1748-9326/ad⦠1/7

Assistant Prof Jon Wang found fire severity increased by 30% between the 1980s and 2010s and total tree cover in #California has decreased by 7% since 1985 due to #wildfires and #drought . @wangathan @uofu_science @UUtah
