A recent study published in the journal Nature revealed that global temperatures have become so hot that some tropical leaves would no longer be able to conduct photosynthesis.
  An international team of scientists from the US, Australia, and Brazil conducted the research. The study said the photosynthesis process in tropical trees begins to fail at about 46.7°C on average. When leaves get too hot, the proteins that convert light energy into sugars stop working.
  Their findings show that the average temperature of forest canopies peaks at 34°C. In some cases, certain areas even exceed 40°C. Currently, 0.01% of leaves have already surpassed the critical point. An expert warned if we do nothing about it, we would see massive death of leaves and trees.
  Tropical forests are an important carbon sink and help regulate the global climate. They cover roughly 12% of the planet and hold more than half of the world’s species, which is why the prospect of tree death raises such alarm bells.
