Gulf Stream passes judgment on Europe
The theme of climate change and the natural disasters and disasters that it carries has been exaggerated for quite some time. In 2004, Hollywood made its contribution, frightening the audience with the disaster film "The Day After Tomorrow", in which the consequence of the cooling of the Gulf Stream due to the influence of human economic activity was shown in a hypertrophied form. Then environmentalists tried to reassure the public with assurances that all this was greatly exaggerated and generally not true.
However, the fact remains. The climate is changing right before our eyes, everyone sees it. A natural anomaly follows an anomaly. Someone connects this with the activity of the heavenly body. Other experts still point to the currents of the oceans and their changes. It is widely known that the climate in Western Europe is significantly milder than in other countries at the same latitudes, due to the natural heating of the warm Gulf Stream. But besides him, there is the North Atlantic Current, a warm continuation of the Gulf Stream, which is divided into two parts in the region of Ireland: one goes south, the second warms up the north-west of Europe.
10 years ago, an anomaly was discovered near Greenland, which may indicate the cooling of the North Atlantic current. This is a piece of water in the ocean the size of a small state that, instead of warming, only cools. Environmentalists gave it the name "cold bubble." In 2015, two records were set: the year was the hottest on the planet, and the “bubble” broke the record for cold. These phenomena cause great concern among specialists. Water in the oceans is constantly moving, mixed with currents in a kind of conveyor. From the south, warmer salt water moves north, where, cooling, they sink to a depth and begin to reverse movement. This process takes hundreds and thousands of years. But due to desalination of waters, this conveyor can stop. And this has already happened.
More than 8 thousand years ago, at the end of the ice age in today's Canada, a huge lake formed from the meltwater of the glacier. Fresh water poured into the Atlantic Ocean, lowered its salinity and temperature, and the North Atlantic current stopped, reversed. Warm waters from the tropics ceased to flow into Northwest Europe, causing a cooling down there, as well as in Scandinavia and the UK.
History repeats itself, environmentalists warn. The melting of glaciers intensifies due to the heating of the planet. The forecast is made that if carbon dioxide emissions alone will double more than the level of the beginning of the nineties, the North Atlantic Current will decrease its strength by three times. Moreover, human activities directly affect the oceans. Researchers estimate that only 13% of its water area has remained untouched. Oceanic waters are also affected by maritime transport, the discharge of industrial wastewater, large-scale fishing, and the entry of agricultural fertilizers into them.
The question is the timing. It is predicted that the warm current heating Europe will stop completely after three hundred years. But the difficulty is that forecasts are built on Technology simulations for which there is little data:
Measurements of water temperature during the course are also carried out as part of the RAPID-AMOC project, and they also show the process of its deceleration. Unlike atmospheric modeling, forecasting across the oceans requires tremendous computing power, which only supercomputers can do.

At the beginning of the XNUMXs, the US launched the Argo project - these are thousands of buoys that measure water parameters at a depth of up to two kilometers and transmit information to satellites. Data is accumulating, but not yet enough
Measurements of water temperature during the course are also carried out as part of the RAPID-AMOC project, and they also show the process of its deceleration. Unlike atmospheric modeling, forecasting across the oceans requires tremendous computing power, which only supercomputers can do.
