United Nations Secretary-General António Guterres described the report as “the red code of mankind.” The United Nations Climate Group said in a landmark report on Monday that global warming is dangerously close to getting out of control, and warned that the world will face more climate damage in the coming decades, if not centuries. In the report of the Intergovernmental Panel on Climate Change (IPCC) scientists stated that humans are “unquestionably” the culprit. Fast actions to reduce greenhouse gas emissions may limit some impacts, but other impacts have now been prevented. Deadly heatwaves, huge hurricanes, and other extreme weather that have already occurred will only get worse.
On Monday alone, he saw 500,000 acres of forest burning in California, while in Venice, tourists wade to ankle depths in the water of Piazza San Marco. In an interview with Reuters, activist Greta Thunberg called on the public and the media to put “enormous” pressure on the government to take action. Three months later, the UN COP26 climate conference in Glasgow, Scotland will try to take more ambitious climate action. Countries around the world, and the money paid for it.
The IPCC report draws on more than 14,000 scientific studies and provides the most comprehensive and detailed picture to date of how climate change is changing the natural world, and what will change unless quick action is taken immediately. emission reduction. According to the report, the global average temperature may reach or exceed the warming threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit) within 20 years. So far, the commitment to reduce emissions has not been enough to begin to reduce the level of greenhouse gases, mainly carbon dioxide (CO2) from the burning of fossil fuels, which accumulate in the atmosphere. In the next ten years, the average temperature may still drop. It will drop to 1.5°C by 2040, and it may drop to 1.6°C by 2060 before stabilizing.
On the contrary, if the world continues to develop on its current trajectory, the rate of increase by 2060 and the end of this century may be 2.0°C and 2.7°C, respectively. The earth has never been so warm since the Pliocene about 3 million years ago, when the first ancestors of mankind appeared, and the ocean was 25 meters (82 feet) higher than today. Trigger feedback loops that release more carbon emissions that contribute to climate warmings, such as the melting of Arctic permafrost or the death of global forests. Under these high-emission scenarios, the earth may bake at temperatures 4.4°C higher than the pre-industrial average in the last two decades of this century.
