China News Service, August 10, comprehensive report, on the 9th, the United Nations Intergovernmental Panel on Climate Change issued a report stating that unless greenhouse gas emissions are significantly reduced in the next few decades, global warming may exceed 1.5 degrees Celsius in the short term.
The Secretary-General of the United Nations said that this report is undoubtedly a resounding "wake-up call."
On August 5, local time, after the wildfire raged, a large number of buildings in Greenville, California, USA were burned down.
[Ten years early! The earth will heat up by 1.5 degrees Celsius]
The report of the First Working Group of the Intergovernmental Panel on Climate Change, published in Geneva, Switzerland, is entitled "Summary for Policymakers" and was completed by 234 scientists over many years.
According to the report, under all emission scenarios considered, "the global surface temperature will continue to rise until at least the middle of this century."
The report predicts that around 2030, the average surface temperature of the earth will be 1.5 or 1.6 degrees Celsius higher than the pre-industrial level.
This is a full 10 years earlier than the time predicted by the working group 3 years ago (the temperature will rise by 1.5 degrees Celsius in 2040).
The report emphasizes that unless carbon dioxide and other greenhouse gas emissions are significantly reduced in the next few decades, global warming will exceed 1.5 degrees Celsius in the short term.
The report pointed out that many changes in the climate system are directly related to increasing global warming, including extreme high temperatures, ocean heat waves, increased frequency and intensity of heavy precipitation, agricultural and ecological droughts in some areas, the scale of severe tropical cyclones, and the Arctic. Reduction of sea ice, snow and permafrost.
The report said that climate change "has affected all regions of the world and caused many extreme weather and climate events."
In the coming decades or even hundreds of years, climate change will bring more deadly heat waves, super hurricanes and other extreme weather.
In recent days, droughts have continued in many parts of the western United States, and California is facing its worst drought since 1977.

["The Deafening Alarm"]
According to the UN website, UN Secretary-General Guterres stated that this report is a "code red" sent to mankind.
This alarm can be said to be “deafening” and the evidence is irrefutable: the greenhouse gas emissions from fossil fuel burning and deforestation are killing our planet and putting billions of people at immediate risk.
Global warming is affecting every region on the planet, and many of these changes are becoming irreversible.
He said: "The world is dangerously close to the internationally agreed upper limit for temperature rise to be controlled within 1.5 degrees Celsius. We face the imminent risk of reaching 1.5 degrees Celsius in the short term. Only step up our efforts and embark on the most ambitious path. In order to avoid crossing this threshold."
Guterres emphasized: "We must act decisively now to save the 1.5 degrees Celsius target."
Finally, he said: “If we unite now, we can avoid climate disasters. But, as today’s report shows, there is no time to delay, and no excuses. I hope that the leaders of governments and all stakeholders To ensure the success of the Glasgow Climate Conference."
