claim: This could mean the landmark Paris Climate Agreement – which seeks to limit global warming to 2 degrees Celsius ( 3.6 degrees Fahrenheit ) above pre-industrial levels – may not be enough to ward off catastrophe.
evidence: Although the parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2 °C ( 3.6 °F ) in the Paris Agreement of 2016, the Earth's average surface temperature has already increased by about half this threshold and current pledges by countries to cut emissions are inadequate to limit future warming.
