Global average temperature could rise to two degrees Cel sius above the norm -the point at which many scientists believe climate change will become dangerous -as early as 2050, a group of experts has warned.
In a report called “The Truth About Climate Change“, they said many people seemed to think of global warming as “abstract, distant and even controversial“. But the planet is now heating up “much faster“ than anticipated, said Professor Sir Robert Watson, a former chair of the Intergovernmental Panel on Climate Change and one of the authors of the report. If their analysis is correct, the majority of people alive today will experience what it is like to live on a dangerously overheated planet. At the Paris climate summit last year, world leaders agreed to try to limit global warming to 1.5 degrees celsius above pre-industrial levels as possible, amid concerns the 2 degrees celsius target may not be safe enough. But in the same year the level of warming reached 1 degree celsius after a 0.15 degree celsius rise in just three years.
Droughts, floods, wildfires and storms are all set to increase as the world warms, threatening crops and causing the extinction of species. The new report warned the 1.5 degrees celsius target had “almost certainly already been missed“.Even if all the pledges to cut emissions are fulfilled, the average temperature is set to reach that level in the early 2030s and then 2 degrees celsius by 2050, they said.
The report said an extra 0.5 degree celsius of warming was expected to take place because of greenhouse gases that have been emitted due to the slow response of the ocean and atmosphere. The experts called for drastic changes to the way the world produces and uses energy with a switch to electric cars among steps that should be taken quickly .
