So this is super interesting! Increased efficiency of water use does not stimulate tree productivity. Once again i long for a savanna face experiment that isn't simply confounded as a fire exclusion experiment.
Increased efficiency of water use does not stimulate tree productivity - Nature Climate Change
The authors theoretically delineate the maximal increases in tree growth that can be expected from increases in plant intrinsic water-use efficiency, which increases with rising CO2. They highlight en...

Congrats 🎉 Dr Eshelman!! @s-eshelman.bsky.social graduated her PhD having completed fab work on the functional ecology of grasses + grazing. Look out for her papers on grazing lawns, intraspecific trait variation and using herbarium specimens to examine grass life histories across Madagascar. 🥂😊👏

Fantastic summary on offsetting - still pervasive in application across many regions of the world and all too easily subject to manipulation www.nature.com/articles/d41...
Carbon credits are failing to help with climate change — here’s why
The idea that emissions can be offset through projects that claim to avoid releases or to remove carbon dioxide from the atmosphere is fatally flawed.

We should come to terms with the fact that forest, shrubland, grassland, and wetland ecosystems cannot offset fossil fuel CO₂ emissions.
But we should still protect and restore them for biodiversity and other ecosystem benefits.
