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.


RULES

1 - Remember the human

2 - Link posts should come from a reputable source

3 - All opinions are allowed but discussion must be in good faith.

4 - No low effort posts.

From Prof. Eliot Jacobson:

Wow! Wow! Wow!

North Atlantic sea surface temperature anomalies are going vertical again. And yes, I needed to extend the y-axis.

Yesterday's temperature of 24.49°C (76.08°F) was 4.2σ above the 1991-2020 mean. The previous high for July 17 was 23.71°C (74.68°F) in 2020.

30 years isn't a hard number, but it can still take 2-3 decades. It has to do with how CO~2~ changes ocean chemistry, which has broad effects on the rest of the climate. https://info.ecogardens.com/blog/what-is-climate-change-lag-and-why-do-we-care

I imagine you noticed this but that second citation (from your edit) has this at the top of the article:

Update August 9, 2020: Please be aware that this article was published in 2010 and that its content is no longer considered accurate. As it still gets regularly linked to from other websites, we will not delete or "unpublish" it. Instead, here is the link to a better take on this topic published by our late team member Andy Skuce in 2013: Global Warming: Not Reversible but Stoppable.
