Tropical forests face ‘massive leaf death’ from global heating, study finds

Tropical forests may become too hot for photosynthesis

Scientists raise the alarm after they found global heating could impair photosynthesis in tropical forests, ushering in potentially irreversible changes.

Tropical forests face ‘massive leaf death’ from global heating, study finds

Some kinds of tree leaf could become too hot to be able to conduct photosynthesis, researchers warnTropical forests could become so hot that some kinds of leaves will no longer be able to conduct photosynthesis, according to a study published in the journal Nature.The photosynthetic machinery in tropical trees begins to fail at about 46.7C on average. The research suggests that forests may be nearing dangerous temperature thresholds sooner than …

Some tropical rainforest leaves are becoming so hot they are unable to photosynthesise, study finds

A tiny proportion of leaves in tropical rainforests are getting so hot they are breaching the threshold at which they can photosynthesise, according to a new study.

Parts of tropical rainforests could get too hot for photosynthesis, study suggests

By Laura Paddison, CNN (CNN) — Some leaves in tropical forests from South America to South East Asia are getting so hot they may no longer be able to photosynthesize, with big potential consequences for the world’s forests, according to a new study. Leaves’ ability to photosynthesize – the process by which they make energy from carbon dioxide, sunlight and water – begins to fail when their temperature reaches around 46.7 degrees Celsius (116 Fah…

The tropics could get so hot that all leaves on rainforest trees die

Satellite sensing reveals tropical forests are much closer to a major tipping point than previously thought, but are only likely to pass it in worst-case warming scenarios
