The southern hemisphere of the Earth was hit by the worst weather disaster in history

At the end of March, a strong storm hit the Mozambican city of Beira, but its residents had nothing to lose - a week earlier, the settlement was destroyed by 90% of the tropical cyclone Idai. This complex natural disaster has been nicknamed the “Southern Disaster, ” because a hurricane of unprecedented force hit regions that, historically, have never experienced anything stronger than an ordinary storm. And experts fear that now this will happen all over the planet.

Cyclone "Idai", like all other cyclones characteristic of southeast Africa, came from the overheated Indian Ocean. This reservoir will not cool down in the foreseeable future - on the contrary, the water temperature in it (as in all the oceans of the world) will rise by 2-3 degrees. Plus it - water - will become more due to the melting of glaciers. Scientists predict that the number of tropical storms (80-100 per year) will generally not increase, but the strength of especially powerful cyclones will increase almost multiply. And their routes will now almost always go on land and move far inland.

The experience of New Orleans and Hurricane Katrina has shown that engineering structures are powerless against a critical load. A huge surge wave makes evacuation senseless - for example, Hurricane Haiyan killed 6, 000 people in 2013. Super-cyclones, like the monstrous Sandy in 2012, can make unpredictable turns, and with good acceleration, they can go hundreds of kilometers deep into the continents - reaching, for example, the American Great Lakes. Residents of coastal cities will no longer be able to escape to the suburbs, sit on a hill and return home.

To make matters worse, hurricanes and cyclones of extreme magnitude are destroying the land itself, provoking erosion, destroying coastlines, damaging infrastructure. Previous methods of protecting people, based on thousands of years of experience of living by the sea, are losing their relevance. And areas that were considered relatively calm, like Ireland or the Atlantic coast of Canada, are now at risk. And every year it grows and grows.
