The 3-degree limit could be exceeded as early as 2050

Jesus Christ I was just recalling 1.5 being a “everything is fucked” Paris agreement number Then it was “some people will survive” 2.5 It’s like 100% of climate scientists were ignored by industry and society

Point of contention: > It can no longer be denied: Climate change is progressing unabated and accelerating. In 2023 and 2024, global average temperatures were 1.5 degrees Celsius above pre-industrial levels for the first time. It is even possible that the 1.5-degree limit for global warming agreed upon in Paris may already have been permanently exceeded. The value they are talking about is the political definition , and not the scientific definition. The political definition requires a +1.5℃ increase to be unbroken across a number of years - 20 years, as set by the IPCC - before it is “accepted”. Not the first year in which warming never again drops beneath +1.5℃, but 20 unbroken years of said minimum. Many scientists consider +1.5℃ to have been reliably and consistently breached at some point in the very early 2010s. And by that same metric we might have already blown past +2℃, which may have happened by 2023. The reason why this is so alarming is because +4℃ is the point at which megafauna - all animals over 45kg, like humans - can no longer survive on this planet. They go extinct. There are adults alive today which will see this come to pass.

Stopping burning coal might be a strong top step towards fixing this. Perhaps replace burning the coal with renewables/nuclear. And simultaneously keep methane leaks as low as humanly possible given how toxic methane is to our protective atmosphere.
