Experimental Evidence for Coordinated Leaf Trait Responses to Elevated CO2 in Five Common Crop Species Understanding leaf trait responses to changing atmospheric CO 2 concentrations ([CO 2 ]) is essential for land- surface modelling. Eco-evolutionary optimality ( EEO ) theory predicts coordinated respo...

An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25...

Why does the optimal temperature of photosynthesis shift with growth temperature and what mechanisms explain this acclimation? Find out in our new paper in @newphyt.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/...

Climate science serves America – and beyond As climate science faces challenging times, Project Drawdown is stepping up with a fellowship for early- to mid-career scientists and engineers.

We believe that climate science serves America — and the world.

That's why we're investing in climate solutions and science, including an innovative fellowship program for early- to mid-career Ph.D. scientists & engineers working on the forefront of climate solutions.

Aridity and drought - distinct concepts too often conflated

It’s the gold standard of US climate research. Contrarians could write the next one. Researchers who have downplayed the threat of global warming have been asked to author the next National Climate Assessment.

I look forward to the legally required, transparent peer review process required by the US Global Change Research Act and the Information Quality Act. I always thought they would try to do a NCA with Judith Curry, five old men and a LLM.

Bob and I were among the hundreds of researchers that were supposed to conduct the 6th U.S. National Climate Assessment. Now it looks like they're gonna produce it with a few people and Grok? Communities need rigorous and accurate information about climate change. This will put communities at risk.
