Our new RSE paper led by postdoc Jingyi Bu is out. Use of GEDI-derived canopy structural complexity metrics improves upscaling of flux tower data. GPP & ET increase with higher structural diversity. Ecosystems w/ complex structures are more resilient to drought

A new study in Nature Climate Change shows contrasting biological production trends over land and ocean. Led by Yulong Zhang at Duke. I am glad to be part of the team. The last study that looked at production over both land and ocean was published in 1998.

Are you a top US-based scientist wanting to relocate to Australia? We are now calling for formal applications from both Australian and non-Australian citizens based in the US whose work is internationally recognised as exceptional.

Our new paper led by Bin & Hankui in ISPRS: Estimating carbon fluxes over North America using a physics-constrained deep learning model. The novelty is to use a time-series deep learning model to jointly estimate NEE, GPP, and RECO while accounting for a physical constraint (i.e., NEE = RECO-GPP).

If you burn down a forest, you don't miss out on lumber for just that season. You have to replant all the trees, nurture them, and wait for them to grow.
The science and research budget cuts happening now are wanton, senseless arson. Recovery, if it ever happens, will take generations.

Whenever I see sidewalks in small cities or towns, I feel happy. But should't sides walks and bike lanes be the norm?
All of this. I've lived with my kids in 4 states, 3 cities, none of them had decent public transit or bike lanes that were safe enough for me to transport kids from home to work, let alone to their doc/shopping/sports locations with all the stuff you need to go anywhere with kids.
OF COURSE cars suck, but so many white anti-car urbanists are folks with no concept of how existing public transit infrastructure makes it all but impossible to navigate the city safely with kids UNLESS you have a car.
ESPECIALLY if you aren't in a wealthy neighborhood.
And guess who that impacts.
