Within a decade, global warming may cause "tipping points" that will have catastrophic consequences for the whole world - scientists
Kyiv • UNN
The report, which was compiled by more than 200 scientists from around the world, addresses five "tipping points" related to global warming. These include the loss of ice cover and the extinction of coral reefs, and require urgent global action to prevent irreversible damage.
Global warming by more than 1.5 degrees Celsius will cause five major "tipping points" in the Earth's systems, which will have catastrophic consequences around the world. This is stated in a major report by climate scientists, reports UNN with reference to Newscientist.
Details
The report was prepared by by more than 200 researchers from different universities around the world. Scientists identify five global "tipping points" that are associated with global warming by more than 1.5 degrees Celsius. A tipping point is a small change in the system is a small change in the system that can cause drastic changes that are difficult to reverse or to reverse or that are irreversible due to the strengthening of feedback processes. feedback processes. Such tipping points are considered to be the loss of ice cover Greenland, the disappearance of the West Antarctic ice sheet, the extinction of of tropical coral reefs, the rapid melting of large areas of Arctic permafrost, and the slowdown in permafrost and the slowing of the ocean current known as the North Atlantic subpolar circulation.
According to David Mackay from the University of Exeter, the slowdown of the subpolar spiral could occur within 10 years and will have serious consequences on both sides of the Atlantic. In particular, it will will cause regional cooling and affect agriculture in Europe and North America, as well as and North America, as well as change the nature of extreme weather events.
All other tipping points will also have catastrophic tipping points will also have catastrophic consequences around the world and will be difficult, if not impossible, to reverse. to reverse, if at all, the report's authors say. Among them are the extinction of seagrass meadows and mangroves, as well as the collapse of fisheries.
Reaching one tipping point can cause tipping point can lead to another in a kind of domino effect. Also, tipping points tipping points in the Earth's system can also cause devastating tipping points in society, such as food security crises, massive population movements and conflicts. It is possible to stop these threats, but it will require urgent global action
Scientists say that limiting further global warming by reducing greenhouse gas emissions emissions to zero will significantly reduce the risk of tipping points. Other measures can also other measures can also help. For example, preventing deforestation in the Amazon will reduce the risk of tropical deforestation and replace it with grasslands as the the region becomes hotter and drier. The report also calls for more efforts to help communities prepare for the impacts of of some of the tipping points, such as sea level rise.
