To survive dry spells, trees stop the water-rich process of photosynthesis. When nature’s natural carbon capture machine grinds to a halt entire forests end up producing more CO₂ than they absorb.

The tiny gardens beneath street trees can boost biodiversity and our connection to where we live.
Some European cities have poor tree shade cover and this is ramping up heat for their citizens.
Ecologists thought the largest trees would be most vulnerable to drought. The reality is more complex, with some forest giants unexpectedly resilient.
Understanding what happened in these forests 56 million years ago may help humanity recognize similar thresholds before we cross them again, the lead author of a new study writes.
By identifying the genes and molecules crucial to resistance in American chestnuts and other species, researchers hope to use genomic techniques to breed trees that can flourish in the face of blight.
Some of South America’s tropical forests effectively stopped absorbing carbon during the 2015-2016 El Niño.
British trees struggle to survive as temperatures get higher, and many die.
Relocating trees to protect forests struggling with climate change seems promising, but the extreme complexity of ecosystems poses challenges.
A hotter, drier and more fire-prone future is putting these unique trees at risk.
Cities benefit from trees, which can cool concrete sprawls and improve air quality.
Forests benefit everyone – but farmers carry the risk.
A new study has shown that more vegetation is not automatically better.
Cytospora canker damages peach trees and decreases orchard production over time.
Two big factors influence the length of the allergy season and how bad people’s allergies will be, and both are expanding.
Mopane worms are an important source of food security and cash income for some rural households.
The tree mix matters. Near Chesapeake Bay, scientists have been experimenting with mini-forests for over a decade. The surprising results show how biodiversity pays off.
Ancient baobabs in Madagascar have unlocked a 700-year rainfall record that is set to help scientists figure out how to adapt to climate change.
Tannin stains on concrete, cars and decks may be unsightly, but that doesn’t mean tannins are unimportant.
Carbon removal strategies may conflict with biodiversity conservation, but careful choices could bring benefits.
