Boom-bust mining towns like Leaf Rapids, Man. are fading into oblivion. Some remaining residents are left fighting for the basic necessities of life, others have fled for survival.

Manitoba's summer wildfire threat was the latest nail in the coffin for once-prosperous Leaf Rapids

1000% agreed. The idea that we have any reasonable confidence in (among other things) the hydrologic cycle response to stratospheric aerosol injection (SAI) is deeply unserious.
Fortunately, last time I expressed my concerns, I was assured that nobody is actually advocating SAI! (lolsob)

My issue with SRM, leaving aside the equity and governance issues (which are IMO insurmountable), is that most (all?) of the research on SRM is based in models which struggle to agree on how even relatively recent volcanic events (our only albeit quite imperfect analog) affect surface climate. 1/2

This is the most amazing (and bad!) warming trend I have ever seen for any mid or low latitude location. Holy moly.
Tehran is on the brink of a severe water crisis.
Multiple factors have left the city unprepared for the current drought, including population growth, mismanagement, and sanctions, but a rapidly warming climate is only adding to their problems.

This is a terribly misunderstood point, even in insurance circles.
Our estimates of the 1 in 100 flood are almost always extrapolations and depend heavily on our assumptions and a few (or zero) real events. In most cases, the 'actual' 1:100 flood could be ~20% lower or higher (at least).

The defense that this was just an adjustment based on better data is self-serving BS.
We do *not* know what the 100-yr flood level is - even if we had perfect DEMs.
Even if we had perfect historical data, non-stationarity means we don’t know what the level is *now*, let alone in the future.

Fire risk: "Why would the federal government go into the business of subsidizing living in areas that insurers don’t want to insure and reinsurers don’t want to cover?", asks @scrawford.bsky.social
Nevada just let property insurers exclude wildfire coverage. Homeowners won’t realize until it’s too late that fire isn't covered. Expect shock, underinsurance, and scrambling for expensive new policies. Plus: pressure for a federal wildfire safety net. open.substack.com/pub/susanpcr...
What happens if property insurers are allowed to exclude wildfires from coverage?
“Are we just going to turn everybody loose and let the fires burn our houses down?” Nevada just did — and others may follow.

The AI industry wants us to believe AI superintelligence is the real threat from generative AI.
But that narrative was crafted to distract from the many ways genAI is being used to tear our societies apart, as we saw this week when a deepfake video rocked the Irish election. It must be reined in.
