Climate report ‘code red for humanity’ – UN

A major UN scientific report has warned the world of increasingly extreme heatwaves and droughts and flooding.

The UN’s Intergovernmental Panel on Climate Change (IPCC) conducted the study, marking the first major review of the science of climate change since 2013.

The climate report is a ‘code red for humanity’, the UN chief has said.

However, scientists have said a catastrophe can be avoided if the world acts fast.

Rapid cuts in emissions of greenhouse gasses could stabilise rising temperatures, scientists say.

UN Secretary General António Guterres said: “If we combine forces now, we can avert climate catastrophe. But, as today’s report makes clear, there is no time for delay and no room for excuses. I count on government leaders and all stakeholders to ensure COP26 is a success.”

The report says “it is unequivocal that human influence has warmed the atmosphere, oceans and land”.

The key points from the report are:

1. Global surface temperature was 1.09C higher in the decade between 2011-2020 than between 1850-1900.

2. The past 5 years have been the hottest on record since 1850.

3. Human interference is very likely the main driver of the retreat of glaciers since the 1990s.

4. It is certain that hot weather extremes have become more frequent and more intense since the 1950s.
