Under extreme heat, plants become CO2 sources as their cuticle degrades and water loss increases - Study shows plants lose more water through their cuticle at high temperatures, weakening their ability to absorb CO2 and accelerating climate change.

Increased temperatures could disrupt the key role of plants in climate regulation.
