World temp set for 2.7°C rise on current emission pledges

What is the news?

Ahead of the scheduled ‘COP26‘ summit of ‘UNFCCC’,the annual emissions gap report has stated that Current commitments to cut greenhouse gas emissions put the planet on track for an average 2.7 degrees Celsius temperature rise this century.

What are the findings of the report?

– Target is to limit warming to below 2°C above pre-industrial levels and ideally to 1.5°C.

– Global warming due to greenhouse gas emissions could breach 1.5°C in the next two decades.

– The updated pledges will only reduce forecast 2030 emissions by an additional 7.5%, compared to the previous commitments. If continued throughout this century, this would lead to warming of 2.7°C.

– China and India, which are together responsible for around 30% of global emissions, have not yet made enhanced pledges.

What is needed to be done?

A 30% cut is needed to limit warming to 2°C for which additional 13 Gt cut in annual emissions is needed by 2030, and a 55% cut is needed to limit to 1.5°C.
