Gates: Limiting global warming to less than 1.5°C is unlikely to be achieved

Beijing time on the evening of November 3, according to reports, Microsoft founder Bill Gates (bill gates) said today that it is doubtful whether the global warming can be controlled within 1.5 ° C. This shows that much remains to be done to meet the global climate targets.

Gates made the remarks in an interview with the twenty-sixth Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change. In the Paris Agreement signed in 2015, world leaders said they were "committed to achieving a reduction in global average temperature to 2 degrees Celsius below pre-industrial levels and to working to bring it to 1.5°C."

On October 31, the G20 Leaders' Summit ended in Rome, Italy. The G20 Rome Summit Declaration, released after the meeting, mentioned that the G20 committed to the paris agreement goals and worked to limit the increase in global average temperature to 1.5°C above pre-industrial levels. This is the first time this goal has been mentioned in an official statement by g20 leaders.

On the same day, the COP26 Conference was held in Glasgow, England. During the meeting, Gates said in an interview with Jeremy Hunt, a British mp, that it was doubtful to achieve the target of less than 1.5°C.

Gates said: "It can be said that it is all about the 'temperature'. Controlling within 2.5 °C is definitely better than within 3 °C; controlling within 2 °C is better than 2.5 °C, and so on. However, it will be very difficult and I doubt we can do it. ”

The threshold of 1.5°C is a key global target, because beyond this level, the so-called "tipping point" is more likely to occur. In the case of the climate system, the tipping point refers to the key threshold at which a global or regional climate moves from one stable state to another. The tipping point is irreversible, and once the tipping point is triggered, the system can quickly deteriorate.

Nevertheless, Gates also pointed out: "The achievements of humanity in responding to climate change are unprecedented. ”
