UN says breaching 1.5C warming limit is imminent and unavoidable
Original title: UN says breaching 1.5C warming limit is 'imminent and unavoidable'
UNEP says the lowest overshoot path needs an 18% emissions cut by 2030 versus 2025 levels.
The UN Environment Programme Emissions Gap report says passing the Paris Agreement’s 1.5C warming limit is imminent and unavoidable. It says the task is to limit overshoot, with a lowest pathway peaking at 1.7 to 1.8C and returning to 1.5C by 2100. That path would need cuts of 18% by 2030, 45% by 2035, and 69% by 2040 relative to 2025. Existing pledges imply about 2.6C peak warming, and current policies about 2.8C.
Unconfirmed: The report says carbon removal at the required scale has not been proven.
- Current pledges yield only a 5-to-8% emissions cut by 2030.
- Fulfilling net-zero pledges still peaks at about 2.1C, the report says.
- The 2.8C policy estimate rose partly after the United States left Paris.
- COP31 climate talks are next month in Turkey.
- Every five years of current CO2 emissions adds about 0.1C of peak warming.

A UN climate report released Wednesday finds the globe will unavoidably slip past the Paris Climate Agreement’s 1. 5-degree Celsius warming target in the next few years. The task now, the report states, is to make the period of warming “overshoot” as limited as possible, eventually bringing global average temperatures back down.
