Weather changes in the 21st century will be increasingly sharp and unpredictable. An international team of scientists for the first time modeled in detail the effects of melting glaciers of Greenland and Antarctica on ocean temperature and air circulation.

Specialists from universities in Canada, the UK, Germany, the USA and New Zealand have concluded that while maintaining the current global government policy, we are expected to increase by an average temperature of 3-4 degrees compared with the pre-industrial period. This will cause a significant increase in the volume of melt water in the oceans and, as a result, the violation of currents and the temperature regime of the planet, says Professor Nick Gollej, the head of a research project.

Scientists claim that their forecast by region is the most accurate to date. For him, they combined highly detailed models of complex climate effects of melting ice with satellite observations of recent processes occurring with glaciers, says EurekAlert.

Scientists predict the fastest rise in world ocean level for the years 2065-2075, which will lead to a change in air temperature.

The flow of the Gulf Stream will weaken, the temperature will rise in the Arctic, Eastern Canada and Central America, and in the north of Europe and on the other side of the Atlantic, on the contrary, it will become colder.

“The water level will not just rise like in a bath,” says Professor Natalia Gomez of McGill University in Canada. “In some areas, for example, in the Pacific Ocean, the sea level will rise, while in the regions near the ice sheets it will decrease.”

By the end of the century, if decisive measures are not taken, the Himalayan glaciers will lose a third of the cover, and this will lead to dire consequences for the 1.6 billion people inhabiting the region. This is another confirmation that developing countries will be more affected by climate change.
