The internationally agreed threshold to prevent the Earth from spiraling into a new superheated era will be “passed for all practical purposes” during 2024, the man known as the godfather of climate science has warned.
James Hansen, the former Nasa scientist credited for alerting the world to the dangers of climate change in the 1980s, said that global heating caused by the burning of fossil fuels, amplified by the naturally reoccurring El Niño climatic event, will by May push temperatures to as much as 1.7C (3F) above the average experienced before industrialization.
This temperature high, measured over the 12-month period to May, will not by itself break the commitment made by the world’s governments to limit global heating to 1.5C (2.7F) above the time before the dominance of coal, oil and gas. Scientists say the 1.5C ceiling cannot be considered breached until a string of several years exceed this limit, with this moment considered most likely to happen at some point in the 2030s.
But Hansen said that even after the waning of El Niño, which typically drives up average global heat, the span of subsequent years will, taken together, still average at the 1.5C limit. The heating of the world from greenhouse gas emissions is being reinforced by knock-on impacts, Hansen said, such as the melting of the planet’s ice, which is making the surface darker and therefore absorbing even more sunlight.
Wow, an expert has been telling us this would happen for 40 years, and we didn’t listen. We’re a fucking stupid ass species.

It’s not that we didn’t listen, it’s that people who would be dead within 40 years made decisions to horde short term wealth instead of ensuring the world would continue for more than a generation or two more. They used their excessive resources to convince people that there wasn’t a problem so that they could keep more money.
And then everyone just shrugged instead of removing their genetic lineage from the gaze of the universe.
What?
I believe they said “eat the rich”
We’ve tried nothing and we’re all out of ideas!
We’re all going to die!
Don’t look up.
EU is warming twice as fast and is above 2.3°C. You can visit and have fun with yet another round of record rainfall and flooding. Discussion about it often goes like “But we enhanced infrastructure to deal with maximum amount of rain! Well yes, but this amount went way over the usual expected maximum.”
Or come in summer to catch a heatwave or two and drought. I hear tourism to cold regions is the new thing now.
But that’s doomerism…. /s
This is the best summary I could come up with:
The internationally agreed threshold to prevent the Earth from spiraling into a new superheated era will be “passed for all practical purposes” during 2024, the man known as the godfather of climate science has warned.
This temperature high, measured over the 12-month period to May, will not by itself break the commitment made by the world’s governments to limit global heating to 1.5C (2.7F) above the time before the dominance of coal, oil and gas.
The heating of the world from greenhouse gas emissions is being reinforced by knock-on impacts, Hansen said, such as the melting of the planet’s ice, which is making the surface darker and therefore absorbing even more sunlight.
“Passing through the 1.5C world is a significant milestone because it shows that the story being told by the United Nations, with the acquiescence of its scientific advisory body, the IPCC, is a load of bullshit,” Hansen said.
For developing countries and small island states at existential risk from sea level rise and extreme weather, the agreed goal is a hard-fought and totemic one, with “1.5 to stay alive” now a common mantra heard at international climate talks.
Even if the world’s temperature is to break the 1.5C barrier, researchers stress that this doesn’t mean that all will irretrievably be lost, with every fraction of a degree added, or not, significant in shaping the severity of climate impacts.
