Glad to be on the Highly Cited Researcher list (Clarivate) again. clarivate.com/highly-cited...

Impressive! for how long? two months?

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

Just searched the entire terminal 5 at LAX and finally found a power outlet on a wall. Come on, it's 2025!

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.

What a nice case study! There happens to be an eddy covariance tower there, and it collected data both and before these events.

So it turns out to be not that bad?

How much was it for FY25?

I knew this would happen. Australia is definitely not the only one. Scientists are vital assets to have for any country.

This is as good as what I got with my professional camera.

ROSES 2025 is finally out. All programs related to carbon cycle, climate change, terrestrial ecology, IDS, ..., have been cut. I knew it wouldn't look good, but I never thought all these programs would be entirely removed.

Widespread and Divergent Post‐Drought Loss of Gross Primary Production ∼23.89% (0.74 Pg C yr−1) of drought-induced gross primary production (GPP) loss occurred during the post-drought periods Higher proportions of post-drought GPP loss were observed in humid regions...

Our new paper in GRL reveals widespread and divergent post-drought loss of gross primary production (GPP). 1/4 of the drought-induced GPP loss occurred after the drought, with a global mean of ∼0.74 Pg C yr−1. Led by Zhuoyi Zhao and Yanlian Zhou.

This is a step backward. But stepping backward seems to be becoming the norm these days.

This is partly why I upload/submit my presentation file as late as possible.

Seriously?

What Are the Environmental Impacts of Artificial Intelligence?  A single AI-focused data center can use as much electricity as a small city and as much water as a large neighborhood. 

How much energy does it take to generate one ChatGPT request? What about water use and the broader climate impact of generative AI? UCS’s José Pablo Ortiz breaks it down, and explains why we need smart policy to guide this tech. Read the blog:

In urban areas, the urban heat island phenomenon will make heatwaves worse.

Simply amazing!

Estimating carbon fluxes over North America using a physics-constrained deep learning model Quantifying terrestrial ecosystem carbon fluxes, including net ecosystem exchange (NEE) of CO2, gross primary production (GPP), and ecosystem respirat…

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).

We should not dismantle science across America The Trump administration is destroying our scientific institutions, its infrastructure, and intellectual capital at an unprecedented pace. Scientists are being fired without cause from many federal ag...

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years.

NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Congrats, Troy!

It is 90 degrees up here in NH today, and it will be 98 on Tuesday.

Climate change increases global farmland area and agricultural emissions, study finds Our mission is to help the world reach “Drawdown" as quickly, safely, and equitably as possible.

A new study published today in @nature.com, co-authored by researchers at the University of Minnesota, Project Drawdown, and other institutions, reveals a troubling feedback loop 🔁:

Okay, it is 50-140 million tonnes of CO2, not carbon. Then the extra carbon sink on a per unit area basis is ~90 - 250 gC m^-2 yr^-1, which can be reasonable. 😀

With around 50-140 million tonnes a year more than the previous estimates and the land area of 150,437 km^2 (South Island), the extra carbon sink would be ~330 - 930 gC m^-2 yr^-1. This extra sink is really high and might be too good to be true.
