The Earth’s southern hemisphere may face longer and more severe droughts in the future, and annual rainfall may drop by about 30%.
After 2050 and until the end of the century, global average temperatures could exceed pre-industrial levels by 3 degrees unless the world’s carbon emissions are reduced. .
“A similar picture was observed in the middle of the Pliocene 3 million years ago, when the levels of carbon dioxide in the atmosphere were 400 particles per million, and the sea surface temperature in the northern hemisphere increased by 9 degrees and 4 degrees in the southern hemisphere,” – the forecasters fear.
This can lead to marked changes in summer precipitation in the subtropical belt, resulting in catastrophic droughts in the tropics and subtropics of the southern hemisphere.
