Scientists find that major Earth systems are on the verge of total collapse

Hidden in every tenth of a degree of extra warmth are hair-trigger switches built into Earth systems that are critical for all life.

When the research team modeled a scenario where temperatures never dropped back below 1.5 °C by 2100, they found that at least one of Earth’s four major systems, or tipping elements, was triggered in roughly 24% of simulations.

An even grimmer scenario – where temperatures peaked near 3 °C before gradually declining – resulted in a 45% chance of triggering a permanent shift by 2300.

“Sticking to current policies could lock us into a 45% chance of triggering irreversible changes by 2300 – even if we later bring temperatures back below 1.5 °C after a temporary overshoot.”

This is a no agenda less moderated variation of !climate@slrpnk.net. Moderation power is not abused and mods do not suppress ideas in order to control the narrative.

Obvious spam, uncivil posts and misinfo are not immune to intervention, but on-topic civil posts are certain to not be subject to censorship (unlike the excessive interventalism we see in the other climate community).
