Report: 2.4C warming likely despite climate summit

London – Despite pledges made at the climate summit COP26, the world is still nowhere near its goals on limiting global temperature rise, a new analysis shows.

It calculates that the world is heading for 2.4C of warming, far more than the 1.5C limit nations committed to.

COP26 “has a massive credibility, action and commitment gap”, according to the Climate Action Tracker (CAT).

The Glasgow summit is seen as crucial for curbing climate change.

But the prediction contrasts with optimism at the United Nations meeting last week, following a series of big announcements that included a vow to stop deforestation.

COP26 is expected to finish this week.

The projection comes as the UK’s Met Office warns that a billion people could be affected by fatal heat and humidity if the global average temperature rises by 2C above pre-industrial levels.

The report by Climate Action Tracker looks at promises made by governments before and during COP26.

It concludes that, in 2030, the greenhouse gas emissions that warm the planet will still be twice as high as necessary for keeping temperature rise below 1.5C degree.

Scientists say that limiting warming to 1.5C will prevent the most dangerous impacts of climate change from happening.

The COP summit held in Paris in 2015 laid out a plan for avoiding dangerous climate change which included “pursuing efforts” to keep warming under 1.5C.

But when governments’ actual policies – rather than pledges – are analysed, the world’s projected warming is 2.7C by 2100, suggests Climate Action Tracker. The Tracker is backed by a number of organisations including the prestigious Potsdam Institute for Climate Impact Research in Germany.

“This new calculation is like a telescope trained on an asteroid heading for Earth. It’s a devastating report that in any sane world would cause governments in Glasgow to immediately set aside their differences and work with uncompromising vigour for a deal to save our common future,” said Greenpeace International’s executive director Jennifer Morgan.

However, the world’s outlook has improved since the Paris climate summit in 2015 when Climate Action Tracker estimated the policies put the planet on track to warm by 3.6C.

Climate Action Tracker blames “stalled momentum” from governments for limited progress towards cutting greenhouse gas emissions by 2030. (BBC)
