All this suffering is so painful and all this harm is so dangerous and so prone to propagate because we are so utterly interconnected to each other and the living Earth. That same feature (it's not a bug) could be the source of our joy and healing.

Climate tipping points are being crossed, scientists warn ahead of COP30
Global warming is crossing dangerous thresholds sooner than expected with the world’s coral reefs now in an almost irreversible die-off, marking what scientists on Monday described as the first “tipping point” in climate-driven ecosystem collapse.

Antarctica may have crossed a tipping point that leads to rising seas. Growing evidence of permanent shift Without adequate sea ice formation, their melting rates will accelerate, with the potential to cause extreme global sea level rise.

Antarctica may have crossed a tipping point that leads to rising seas
Scientists are beginning to understand the sudden loss of sea ice in Antarctica – and there is growing evidence that it represents a permanent shift with potentially catastrophic consequences

This is not a particularly new finding; as Susan Soloman and colleagues put it in their groundbreaking 2009 paper, "the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop" www.pnas.org/doi/10....

Overpumping of groundwater accounts for 44‰ of global sea level rise—versus 37% from Greenland + 19% from Antarctica. Because after water is put to human use, it escapes into the ocean.
And groundwater is a finite resource. In some areas, so much has already been drained, aquifers have collapsed

Groundwater is drying out, heating up, and causing sea level rise
Overuse of groundwater has created zones of “mega-drying” around the world — and caused more sea level rise than Greenland’s ice sheets.

There’s a thing in wargames and strategic sims where you can tell from the jump where an opponent is going land their first blows, and there’s fuck all you can do to prevent it, and the trick is to stay focused and not let despair become an opposing force multiplier.

This is the gold standard measure of atmospheric carbon, the one you see in almost every chart that tracks emissions.
The Trump administration is planning to cancel its lease at a government laboratory in Hawaii, a site where scientists support key observations of surging greenhouse gas levels in the atmosphere, according to a list obtained by Democratic members of Congress and shared with The Post.

Humans evolved during a remarkably stable climate period when C02 hovered between 200 to 280 ppm. We are now north of 400 ppm with no end in sight and why isn’t this fact dominating every political conversation?
