The Earth is on track to warm up by 2°C unless governments double their efforts to limit greenhouse gas emissions.
That’s according to a report by climate experts led by Sir Robert Watson, former Chair of the Intergovernmental Panel on Climate Change.
They believe the target set in the Paris Agreement of 1.5°C of warming is “not achievable” as it could be reached by early 2030 and 2°C 20 years later even if all nationally determined contribution (NDC) pledges are fulfilled.
To stop the planet reaching 2°C of warming, scientists recommend reducing emissions quickly over the coming decades with a view to reaching net zero CO2 emissions by between 2060 and 2075.
Last year, average temperatures reached 1°C higher than pre-industrial times.
Mr Watson said: “Climate change is happening now and much faster than anticipated. While the Paris Agreement on climate change is an important step in the right direction, what is needed is a doubling or tripling of efforts. Without additional efforts by all major emitters, the 2°C target could be reached even sooner.”
