Collapse

This is the place for discussing the potential collapse of modern civilization and the environment.

Collapse, in this context, refers to the significant loss of an established level or complexity towards a much simpler state. It can occur differently within many areas, orderly or chaotically, and be willing or unwilling. It does not necessarily imply human extinction or a singular, global event. Although, the longer the duration, the more it resembles a ‘decline’ instead of collapse.

1.5 is dead: How hot will the Earth get? (climateandcapitalism.com)

2024 was the warmest year since records began being kept 175 years ago. According to the World Meteorological Organization’s latest State of the Global Climate report:

Each of the past ten years set a new global temperature record.

Each of the past eight years set a new record for ocean heat content.

The 18 lowest Arctic sea-ice extents on record were all in the past 18 years.

The three lowest Antarctic ice extents were in the past three years.

The largest three-year loss of glacier mass on record occurred in the past three years.

The rate of sea level rise has doubled since satellite measurements began.[1]

There is no room for doubt: Earth is getting hotter. The question now is how hot will it get?

The IPCC targets are for the current century. Predicting human technology or even human existence any further than that is a bit of a fool's game. And the rest of the planet will obviously go on without us, 10 degrees hotter for a while until feedback systems kick in. Having taken the hit to biodiversity.

But sure, that's interesting information.

At 10° it's the new equilibrium. Not "for a while". Not "until feedback systems kick in". After the feedback systems stop the increase it will be 10° hotter and stay there for tens of thousands of years.

Exactly. Until the feedback systems kick in. Earth's temperature has been a rollercoaster ride in geological time. As you surely know already.
