Scientists have long warned about the extreme risks of global warming by 2°C or more above the pre-industrial mean temperature. Governments adopted this upper temperature limit, including keeping the possibility of adjusting this to 1.5°C due to severe risks, back in 2009.


The limit has been reaffirmed every year since then.

Despite this, the world remains dangerously off track, on a path to a 4-6°C increase in mean surface temperature by the end of the 21st century. Note that 2°C is not a target but an upper limit, or a global “guardrail” to prevent disastrous climate change.
