Extreme heat waves, droughts, floods and storms are becoming more frequent and more severe. A new study modeling the Earth’s future by 2100 shows that gradual changes in temperature and precipitation could change the climate so much that maps will have to be redrawn.

From the Arctic to the tropics

According to estimates, between 38 and 40 percent of the world’s land will be in a different climate zone by the end of the century.

• Currently, areas with an arid climate occupy about 30 percent of the land. They will cover 34 percent by 2100.
• The tropical zone will also expand significantly. Such changes can disrupt food production systems and lead to the spread of mosquito-borne diseases to new areas.
• The study showed that the biggest shifts towards the new climate are expected in the colder climate regions of Europe and North America. By 2100, 89% of Europe and almost 66% of North America could move to another climate zone.
• The most drastic changes will occur in the polar region, which from 1901 to 1930 covered almost 8% of our planet’s land area and has already shrunk to 6.5%.

Since the beginning of the 20th century, 14.77 percent of the Earth’s land area has undergone a change in climate classification, with the most significant changes observed in North America, Europe and Oceania.
– shows the analysis.

The study concludes: If we don’t take action to reduce emissions soon, the pace of global warming will continue to accelerate and eventually change the Earth beyond recognition.. As a result, vulnerable species and agricultural practices will have less time to adapt to climate change than previously thought, the scientists warn.
