In the southern hemisphere of the Earth, the period and power of droughts will increase in the future, scientists warn. Annual rainfall in those regions could be 30% lower than current levels.

Climate change has already begun. Thus, by 2024, the average global temperature will rise by 1.5 ° C compared to the pre-industrial era, that is, from the middle of the 19th century, and between 2050 and 2100 this figure will increase to 3 ° C, if carbon emissions are not reduced now. A similar situation occurred during the Middle Pliocene about 3,000,000 years ago. Both then and now, atmospheric carbon dioxide reaches 400 parts per million, and sea surface temperatures at high latitudes are 4 ° C higher in the Southern Hemisphere and 9 ° C in the Northern. All of these factors will adversely affect the amount of summer rainfall in tropical and subtropical zones, resulting in prolonged and severe droughts in the Southern Hemisphere.
Earlier, Alexey Karnaukhov, senior researcher at the Institute of Cell Biophysics, Russian Academy of Sciences, named the global dangers that threaten humanity.
