You're living through one of the biggest technological transformations in world history and it has nothing to do with AI

Grid scale batteries are changing our electricity system. Excellent new visual story on batteries in FT today shows just how far this technology has evolved.

Fasten your seatbelts, this is just the beginning.

Western Alaska is in crisis
Typhoon Halong has devastated communities across the Y-K Delta-flooding homes, displacing families, and cutting off access to clean water, power, and medical care. Entire villages like Kipnuk, Kwigillingok, and Napakiak are in urgent need of rescue, shelter, and supplies.

NEW: There’s a disaster unfolding in Alaska right now. And no major network is covering it.

The remnants of Typhoon Halong battered western Alaska overnight. Homes, with people in them, have literally been swept into the Bering Strait.

At least 20 are missing. No comment from any federal agency.

The surf is up to the dunes in Bethany Beach (left) -- thanks to this developing Nor'easter offshore. Same deal in Rehoboth (right).
Coastal flood warnings and high wind warnings in effect for the Atlantic coast into Monday.

No lack of storms this hurricane season, and certainly no shortage of major hurricanes -- but they've thankfully managed to avoid land for the most part.
The most impactful storm so far was Imelda's landfall on Bermuda.
But it's not over yet...

There is a risk of significant flash flooding in parts of interior SW today as deep tropical moisture associated w/remnants of East Pacific #HurricanePriscilla interacts w/jet streak associated w/an incoming trough. Risk will be highest central/northern AZ and SW UT. #AZwx #UTwx
Excessive precipitation (i.e., flash flood risk) outlook from NOAA's WPC for today (10/6/2025) as visualized on pivotalweather.com. It shows a broad region of slight risk over the interior U.S. Southwest, and a two substantial lobes of moderate risk (i.e., second-highest tier) over northern Arizona and southern Utah, respecitvely.

Next week is looking quite active in CA as a high-amplitude flow pattern develops over North Pacific in downstream response to perturbation of jet stream by West Pacific #TyphoonHalong. NorCal looks quite wet & stormy (rain & iso. tstms/mtn snow); SoCal impacts TBD. #CAwx #CAfire
Snapshot from ECMWF ensemble of an unseasonably deep low pressure system centered just west of San Francisco by early next week. It will likely bring widespread rain, isolated thunderstorms, some mountain snowfall, and possibly some gusty winds though exact path and impacts remain TBD.

this is correct. and while you would get a nontrivial one off sum from a billionaire tax (not enough for a welfare state, but a lot), the ongoing point of that tax would be prevent billionaires from existing

The entire city of Kotzebue, Alaska, is being evacuated for potential record coastal flooding. Kotzebue is the "hub" community for northwest Alaska. @alaskawx.bsky.social

Anyone have a good source of tide/inundation forecasts beyond the 48 hours on NOAA Tides & Currents site? I seem to remember that Stony Brook University used to have something, but I can't find it.

WPC has initiated Key Messages for an impending coastal storm that will look to generate strong wind gusts, heavy rainfall, and significant coastal impacts that include coastal flooding, rip currents, and beach erosion along portions of the East Coast over the upcoming weekend.

One important part of the possible coastal storm is that winds will be roughly from the NE. This is already a rare direction, and last winter featured basically zero nor'easters.

*If* ~45 mph NE gusts occur in Long Island, it could be 1000+ days since the last occurrence. Rare wind = more damage.

This extratropical transition will perturb the jet stream and could cause a major early-season rain and snowstorm in California next week. Stay tuned! #CAwx

Energy from Typhoon Halong near Japan may amplify the jet steam (excite the storm track) across the Northern Pacific / western North America this weekend. Scientifically known as tropical cyclone recurvature & extratropical transition.

We probably need to go back to ~350 ppm CO₂ equivalent for temperatures to stop rising.

We are now above 573 ppm (GHG forcing of +4.1 W/m²).

That's without aerosols cooling things down.

There's too much uncertainty to be sure, but going back to 350 ppm is already a Herculean task.

A trio of cyclonic eddies in the Gulf of Mexico are creating record-high Ocean Heat Content values for the date. Absolutely something of importance during this part of hurricane season.
