Earth Is Set For Disastrous 2.7°C Temperature Rise Under Nations' Current Net-Zero Pledges

 Unless world leaders seriously up their pledges at the COP26 climate change conference next week, the planet is set for a 2.7°C (4.8°F) rise in global temperatures by the end of the century, according to a new UN report. This would be a disastrous rise in temperature, bringing with it a significant increase in droughts, floods, heatwaves, and the death of coral reefs.

The findings, from the UN Environment Programme (UNEP)'s annual Emissions Gap Report 2021, show that current pledges are nowhere near limiting global temperatures to 1.5°C (2.7°F) above pre-industrial levels, the limit set by the Paris Agreement in 2015 that would mitigate some, but not all, impacts of climate change. This echos the findings from think tank Climate Action Tracker last month that not one of the world's largest emitting nations is on track to meet their Paris Agreement goals. 

The report argues current pledges would reduce carbon by only about 7.5 percent by 2030. However, to limit warming to 1.5°C, the planet needs to slash emissions by up to 55 percent. To limit warming to 2°C (3.6°F) — a much less desirable target that would see many harsh effects of climate change — emission reductions of 30 percent would still be needed. 

In short, current pledges to cut greenhouse gas emissions announced before the run-up to COP26 are falling drastically short and time is running out.

“Climate change is no longer a future problem. It is a now problem,” Inger Andersen, Executive Director of UNEP, said in a statement. “To stand a chance of limiting global warming to 1.5°C, we have eight years to almost halve greenhouse gas emissions: eight years to make the plans, put in place the policies, implement them and ultimately deliver the cuts.

“The clock is ticking loudly.”
