"Of all the troubling news in the Intergovernmental Panel on Climate Change
(IPCC) report out on Monday, one warning will surely generate the most
headlines: under all scenarios examined, Earth is likely to reach the crucial
1.5℃ warming limit in the early 2030s.
As the report makes clear, global warming of 1.5℃, and then 2℃, will be
exceeded this century unless we make deep cuts to CO₂ and other greenhouse gas
emissions in coming decades.
Climate change and its consequences are already being felt. Beyond 1.5℃, the
situation is likely to rapidly deteriorate.
We are among the climate scientists who contributed to the latest IPCC report,
including on the question of 1.5C℃ warming. Here, we go beyond the headlines to
explain how the 1.5℃ rise is measured – and why maintaining the lowest global
warming possible is what really matters."
