Although the world’s top climate scientists stated that the earth is warming faster than ever due to man-made reasons, but they also emphasized that taking quick and active actions to reduce the emission of endothermic pollutants can stabilize the temperature within decades. .
Monday, the United Nations Intergovernmental Panel on Climate Change (IPCC) released Sixth Assessment Report On the causes, effects and effects of global warming.
Some key information:
- Since the late 19th century, man-made emissions of carbon dioxide, methane and other gases have warmed the earth by 1.1 degrees Celsius, and the temperature may rise to 1.5 degrees Celsius in the next 10 to 20 years.
- The earth is the warmest in more than 125,000 years. The carbon dioxide level in 2019 is the highest level in 2 million years.
- Scientists are more confident than ever to link sea level rise, melting glaciers, extreme temperature events, extreme storms and rainfall events, droughts and fires, and other changes to climate change.
- If we can reduce carbon dioxide emissions so that more carbon is absorbed from the atmosphere than released into the atmosphere, we can gradually reverse the warming trend. But sea level rise is another matter-this may require “Centuries to For thousands of years, the global average sea level will reverse. ”
The report was created by 234 authors from 66 countries.
Kyle Armour, an associate professor and climate scientist at the University of Washington, is the lead author of the report.He says Seattle Times Climate change is affecting every region on the planet.
“Climate change is indeed widespread and intensifying, and many changes are unprecedented in thousands of years,” Armor said.
The number that impressed me was the potential to heat 1.5 degrees Celsius in just ten years. In the past century, the temperature has risen by a little over 1 degree. My hometown in the Pacific Northwest has been affected by drought, nightmarish wildfires and surreal thermal domes in June this year. The famous area has set an unprecedented temperature record. Damp, mossy luster.
What would happen if we rose by nearly half in such a short period of time?
The IPCC report pays more attention to the importance of setting and achieving ambitious near-term carbon reduction targets.Governments of the world will meet in Glasgow this fall United Nations Climate Change Conference of the Parties (COP26) Set emission reduction targets for their country.
In the Northwest, tech giants have been setting their own climate agenda.
- Microsoft remains the leader, and its goal is to achieve negative carbon emissions by 2030. In January of this year, the company announced that it would reduce its carbon emissions by 6%, from 11.6 million metric tons to 10.9 million metric tons. It also paid for the removal of an additional 1.3 million tons of carbon from the atmosphere.
- Amazon’s goal is to be carbon neutral by 2040. Last year the company disclosed that its emissions actually increased by 15% from 2018 to 2019.Amazon is responsible 51.2 million tons The amount of carbon dioxide is roughly the same as Singapore’s footprint.The company continues to invest Renewable Energy Project It is also the largest corporate buyer of renewable energy in the United States and Europe.
- Both Amazon and Microsoft support some key climate legislation in Washington State, and in May Governor Jay Insley signed into law the most ambitious package of climate policies that many have described as the United States.
