Keeping below 1.5°C is not possible

Mar 19, 2025 | Climate Literacy

I love Guterres for his outspokenness on the #ClimateCrisis but he loses credibility when he says stuff like this (re the new WMO State of the Climate report)

“This report shows that limiting long-term global temperature rise to 1.5°C is still possible.”

Someone needs to give him the 2024 UNEP Emissions Gap report!

“Altogether, this implies that rapid and deep annual emission reductions of about 9.0% are needed [annually] from now until 2030 to bridge the emissions gap for a below 1.5°C pathway.”

Or put another way:

“Cuts of 42% are needed by 2030.”

This is clearly not going to happen! The largest reduction we have ever achieved is 4.7% during the early phase of the COVID pandemic (2019 to 2020)

The idea of staying below 1.5°C is dead.

In fact in the ERA5 dataset, as of February 2025 we are set to pass 1.5°C permanently in about September of 2029 - that is 4 years from now.

Take a look:

Even staying below 2°C is in serious doubt.

Again from the 2024 UNEP Emissions Gap Report:

We honestly need to stop with this “1.5°C is still possible” nonsense!
