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).

We have recently revised the temperature threshold. Up to 2022, the Intergovernmental Panel on Climate Change (IPCC) said the tipping point for coral reefs would occur when warming is between 1.5C and 2C above preindustrial levels. But in 2023, we revised that to between 1C and 1.5C. The world is already close to that upper limit and it will certainly come within the next 10 or 20 years as a result of committed climate change – which comes from cumulative emissions that have already gone into the atmosphere. So have we already gone past the tipping point for coral reefs in global terms? Perhaps.
