Global Average Temperatures Of Select Nations: A Report Card

While the world has already reached the threshold of a 1.5°C increase in global temperatures, many scientists believe it is still possible to get back on track. According to the 2023 UN Emissions Gap Report, this would require a 42% cut in our emissions. It would take a 28% reduction to keep emissions below 2.0°C by the end of this century. A tool on the Berkeley Earth website shows each nation’s emissions in 2022, their current trajectory by 2100 and where it could be if all net zero pledges are met.

The Quada Project: Beyond 1.5°C

The consensus of scientists is that limiting the global temperature rise of 1.5°C is no longer reachable, but limiting it to below 2.0°C is possible, according to an analysis of global information undertaken by the Inevitable Policy Response study from Britain (Jacob Thomae, New Scientist, 2 December 2023, “Keeping our Cool”). We were once on a path to 3.5°C, which has been reduced to 2.4°C by 2100. But the IPR study thinks that we have a 90% chance of holding the temperature increase to between 1.7 and 1.8°C, primarily because of the progress that has been made on green energy since the Paris Agreement in 2015. This is the good news.
