The ice shelves of the Pine Island glacier and Thwaites glacier have begun to fracture, according to a new study published today.

These are, quite simply, the most important chunks of ice in the world, and they will likely determine (in part) the fate of our civilization.
Back in 2017, I described this scenario as the beginning stages of an "ice apocalypse":

As always, @chriscmooney has a masterful description of exactly what today's study means.

In short, the natural brakes on the glaciers are shearing off. Their flow towards the sea is accelerating.

The paper itself is worth a look too, it's very clearly written.

It's sure to further elevate the swarm of scientific interest in this extremely important part of the world.

If we lose the West Antarctic Ice Sheet, life as we know it will change, permanently.

We are in a climate emergency.

As terrifying as Sally's rapidly-intensifying winds are, its biggest threat is likely going to be incredibly heavy rainfall.

Latest forecasts are for a 3-4 day slow loop over southern Mississippi & Alabama, and up to 27 inches of rainfall.

Be prepared for catastrophic flooding. a graphic showing predicted rainfall from hurricane Sally, s
Scenarios that come to mind:

Danny (1997) - Alabama
Georges (1998) - Mississippi
Allison (2001) - Texas
Florence (2018) - Carolinas

These storms brought 25-35 inches of rain over a span of four days, about what Sally is expected to do.
There's increasing scientific consensus that slow-moving, rapidly-intensifying, extremely heavy rain producing hurricanes on the Gulf Coast -- like Sally -- are going to be a hallmark of climate change.

NHC not holding back in their latest update on Hurricane Laura:

"Unsurvivable storm surge with large and destructive waves will cause catastrophic damage" Key Messages:  1. Unsurvivable storm surge with large and de
Just, incredible incredible stuff. Hurricane Laura will alter history for this part of the Gulf Coast.
NHC just boosted the storm surge forecast to historic levels in Louisiana.

20ft of surge would put Hurricane Laura into rare territory in the 140-year recorded history of hurricanes on the Gulf Coast, on par with Ike (2008) and Galveston (1900).

This is a dire emergency. A map of forecasted storm surge from Hurricane Laura, showin

A review by climate scientists of the major claims of @shellenbergermd's new book Apocalypse Never (which will likely debut on the New York Times bestseller list) found that it has "misleading and overly simplistic argumentation about climate change".

climatefeedback.org/evaluation/art…
"The reviewers who analyzed this article rated its overall credibility to be low. In their comments, the scientists evaluate many of these claims and describe how they are inaccurate or mislead readers by contradicting available evidence or using scientific data out of context."
In a direct statement to me, Michael Shellenberger's publisher said that the book is specifically marketed to climate deniers.

Shellenberger has been appearing almost exclusively on right-wing TV, radio, print, and podcasts to promote the book.

nothing about this plan is ambitious or reassuring

bloomberg.com/news/articles/…
if this is the Democrats starting point, we are seriously and truly fucked
"The plan, written by the Democratic majority on the bipartisan committee, also sets a goal of achieving net-zero emissions for the electricity sector by 2040."

This goal is about 10-15 years too late.

Minnesota State Capitol, right now

A few thousand people here already, very visible National Guard presence (uniformed soldiers passing out water bottles), very peaceful atmosphere so far.
Another angle, just below the steps of the Minnesota State Capitol. People chanting: "Black Lives Matter"
The only sounds during the moment of silence at the Minnesota State Capitol is the police helicopters overhead

Update on Cyclone Amphan:

- The most powerful storm to threaten India & Bangladesh in 20 years
- 10,000,000 affected – just in Bangladesh
- 500,000 families now homeless – just in Bangladesh
- 100+ people dead and missing so far
- Critical levee failures in the Sunderbans delta
The effects of Cyclone Amphan on the Sunderbans cannot be understated. Local journalists are already warning of a "death knell" for the region, home to 4 million people.

Amphan's storm surge has sent a deluge of saltwater on farmlands & freshwater swamps.
telegraphindia.com/calcutta/cyclo…
“A reverse migration is taking place because of the novel coronavirus with tens of thousands of people returning to the Sunderbans. The storm is like a death knell for these people.”

This is what the climate emergency looks like in marginalized places.
