This is the warning in a report issued to governments ahead of COP26, the 2021 United Nations Climate Change Conference to be held in Glasgow in November.
The report predicts that agricultural output could fall by 30 per cent by 2050, even if the amount of food needed by a growing population is projected to increase by 50 per cent, according to the Royal Institutes of International Studies. (Chatham House). Among them, maize is particularly affected. The team predicts a drop in yields of at least 10 percent in the US, China, Brazil and Argentina, where the majority of agricultural crops are grown.
More than 400 million people will be “unable to work outdoors” by the 2030s, with about 10 million deaths predicted due to “temperature stress,” the report said.
According to the researchers, by 2040, nearly 700 million people a year are likely to experience severe droughts lasting at least six months, and by 2050, more than 70 percent of people in all regions of the world. The world is likely to experience heat waves.
… lack of clean water…
The number of floods will increase by the beginning of the next century. The study’s authors warn that nearly 200 million people worldwide will likely live below the flood level for 100 years, when water begins to flood the surrounding area. Nearly 60 million people are likely to be affected by flooding due to rising sea levels.
The current probability of flooding is once every 100 years when the average sea level rises by just 1 meter, 40 times for Shanghai, 200 times for New York and 1,000 times for Kolkata.
At the current rate of global decarbonisation, the world is on track to warm at least 2.7°C by the end of this century, well above the 1.5°C target.

The report notes that new proposals by some governments to cut emissions further fall short of their targets, while a number of major economies have yet to commit to any further reduction targets. any emissions.
At COP21 in Paris in 2015, countries agreed to try to limit global warming to 2°C above pre-industrial levels to contain the climate crisis.
Dr Daniel Quiggin, a senior research fellow at Chatham House who co-authored the report, said there was also “the possibility that events related to climate change would take place more and more, causing a chain of problems in connectivity between regions and sectors, causing trade disruptions, political instability, increased migration, more infectious diseases or even armed conflict”.
