Countries only have a limited time in which to act if the world is to stave off the worst effects of climate change. 2021 could be a crucial year in the fight against global warming.
In November, world leaders will be gathering in Glasgow for the successor to the landmark Paris meeting of 2015.Paris was important because it was the first time all the nations of the world came together to agree they all needed to help tackle the issue.
The problem was the commitments countries made to cutting carbon emissions back then fell way short of the targets set by the conference.
In Paris, the world agreed to avoid the worst impacts of climate change by trying to limit global temperature increases to two degrees Celsius above pre-industrial levels by the end of the century. The aim was to keep the rise to 1.5C if at all possible, but we are way off track.
With current plans, the world is expected to hit three degrees Celsius of warming by the end of the century.
