Photosynthesis in the forest may stop due to heat. writes about it CNN.
The leaves of some plants in the tropics lose their ability to photosynthesize, which can have negative consequences for the environment. The limiting temperature for photosynthesis is considered to be 46.7 ° C, and it is sufficient for the temperature of the leaves to rise, not to this level of air temperature. This conclusion was reached by the results of the work of scientists from the USA, Australia and Brazil.
At the same time, it was noted that currently 0.1 percent of all leaves cross the critical threshold, but if the global temperature rises by 4°C, the critical threshold will be crossed. It was noted that such a significant temperature increase on the planet is not yet expected.
