The latest IPCC report: Global warming exacerbates extreme climate disasters, and countries must strengthen energy-saving and carbon-reduction actions

The latest scientific report released by the United Nations Intergovernmental Panel on Climate Change (IPCC) pointed out that the extreme weather conditions that occurred around the world this summer are only a mild “rehearsal” for the next few decades, and called on all countries to take immediate action.

In this summer full of fires, floods and heat waves, scientists once again remind people: If more fossil fuels continue to be used in the future, it will rapidly increase the impact of global warming. The scientists concluded in the report that only by immediately taking emergency measures to stop greenhouse gas emissions can the planet be prevented from warming up to a dangerous state by the end of this century.

The IPCC released the final draft of WGI AR6 for the first working group report of the 6th Climate Change Assessment Report (IPCC AR6) on August 9. The report pointed out that global warming is exacerbating heat waves, heavy rains, droughts and tropical climates. Deadly extreme weather events such as storms will affect every area of ​​the planet. The new report provides a “clear” message that humans are heating the earth to a dangerous state, causing large-scale and rapid changes in the atmosphere, oceans, and permafrost, which in turn affects the entire climate system and the biosphere.

The new climate model has more accurate climate system data and also helps make the most accurate predictions to date. If greenhouse gas emissions cease, how will the climate react? Although there are still some doubts about how much carbon dioxide will be absorbed and released by permafrost and forests in the future, the report shows that the climate will begin to stabilize 20 to 30 years after the concentration of greenhouse gases stabilizes.

The report found that global warming is changing the earth’s water cycle, and there is no doubt about it. This will bring more intense rainfall and flooding, as well as more severe droughts in many areas. At high latitudes, rainfall may increase, but in many subtropical areas where water is already scarce, rainfall is expected to decrease.

Although the IPCC reports in the past were the basis for the commitment to respond to global warming, the actual actions taken by the governments of various countries did not meet their commitments, and were far from the “goals that must be achieved” required by science. This new report shows “how bad things have become, and why the world needs to act faster in accordance with science.” The participation of environmental organizations helps ensure that the IPCC does not deviate from the 1.5 degrees Celsius warming target, but it is difficult and full of challenges.

Scientists have recently analyzed 40 years of data from 800 snow sensor networks and found that in the past 40 years, about half of these sites have lost 50% of their spring snow; if there is no mountain snow, many parts of the world People will suffer. Our current decisions will determine our future consequences, and we must do something for us and the next generation.
