In 2015, the countries participating in the United Nations Framework Convention on Climate Change (UNFCCC) signed the Paris Climate Change Accord and agreed to keep the increase in global average temperature 'below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.'In 2018, the UN warned that with this target, we had 12 years to limit the climate crisis.

The latest warning from the UN's Intergovernmental Panel on Climate change (IPCC) report released last month, was more urgent: the world is warming up faster than previously thought.
