A time of catastrophes and polycrisis

We have developed the capacity to do indirect harm by altering conditions necessary for survival. It is a closure of the human climate niche (the conditions that sustain human life).

* A catastrophic climate event is upon us. Here is why you’ve heard so little about it, George Monbiot
"This shift, on any realistic human scale, would be irreversible. Its speed is likely to outrun our ability to adapt." >>

"Continued global heating could trigger climate tipping points, leading to a cascade of further tipping points and feedback loops ... This would lock the world into a new and hellish “hothouse Earth” climate far worse than the 2-3C temperature rise the world is on track to reach. ... The assessment, which was published in the journal One Earth, synthesised recent scientific findings on climate feedback loops and 16 tipping elements." https://www.theguardian.com/environment/2026/feb/11/point-of-no-return-hothouse-earth-global-heating-climate-tipping-points

The risk of a hothouse Earth trajectory: massive, sometimes abrupt, and undoubtedly disruptive. A much less habitable state of the climate for us.

"The world is closer than thought to a “point of no return” after which runaway global heating cannot be stopped, scientists have said."

"The public and politicians were largely unaware of the risk of passing the point of no return, the researchers said. The group said they were issuing their warning because while rapid and immediate cuts to fossil fuel burning were challenging, reversing course was likely to be impossible once on the path to a hothouse Earth, even if emissions were eventually slashed."

“We know we are running profound risks on the current climate trajectory, which we can’t rule out could turn into a trajectory towards a much less habitable state of the climate for us. " >>
