According to the new study, by 2100 the average annual temperature will rise more than 2 degrees Celsius with a probability of 95%. These 2 degrees are the threshold at which excess warming becomes catastrophic, HiTech writes citing Business Insider. Researchers believe that there is only 5% probability that by 2100 the planet will not heat up more than 2 degrees Celsius. The purpose of the Paris Agreement was to set emission standards that would keep the world temperature at the same level. Ideally, warming should not exceed 1.5 degrees. However, now the researchers came to the conclusion that, even if governments continue to take action, the temperature increase by 2100 will be about 3.2 degrees Celsius. Warming by 1.5 degrees can happen already by 2026. According to the ecologist Bill McKibben, if the temperature rises by 2-4 degrees, a huge part of the world's population will not be able to cope with the heat by the end of the century. The level of the world's ocean will rise so much that most of the world's largest cities will be under water, and the ocean itself will turn into a "hot, sour, choking soup". "If this is not hell, then a place with a similar temperature," - so McKibben calls the Earth of the future. Some scientists even believe that the disaster is inevitable in 2020. However, not everything is lost and there are measures that can help to keep warming.

Activists in many countries are in favor of taking appropriate measures, clean energy is being developed, and states and cities of the United States have promised to implement the Paris agreement, despite the fact that President Donald Trump plans to withdraw America from this document. Climate scientist James Hansen believes that we may need to develop technologies for "negative emissions" that will "suck" carbon from the atmosphere. And in Arizona they are planning, as an experiment, to spray ice particles in the stratosphere in order to "cool" it. All these efforts can not completely stop the warming - but they can limit the heating of the Earth to 2.5 degrees instead of 4.
