I made a list (or 'starter pack') of Land Surface Modelers, because that's the kind of thing one does on #bluesky. Please tell your friends and also (v. important) TELL ME if you want to be added. We need more people here! go.bsky.app/Mw4tJ3t

Glad you liked it. I added you too now :) also congrats on your Amazon paper!

Amazon forest resistance to drought is increased by diversity in hydraulic traits - Nature Communications

The hyper-diverse tropical forests of the Amazon store vast carbon stocks, but whether this diversity increases their resistance to future drought remains uncertain. This simulation study suggests that higher diversity in plant functional traits increases biomass resistance to both short- and long-term drought.

How is this happening, that random gangs of bribed vigilantes are hunting people in the streets of formerly civilized cities? I know there is a lot to process right now, but this one got to me more than most.

Rebecca Solnit @rebeccasolnit.bsky.social · 10d

The stage of deterioration where gangs of large (mostly) white men just publicly assault people who seem to be brown because they're brown in the hopes of doing far more harm to them in the name of the state. Glad this one escaped.

Man, this has been too true for too long. And beyond, "Okay, but get a heat pump" there's also "here's how to get a heat pump" and "here's a great installer."

Kate Marvel @drkatemarvel.bsky.social · 10d

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

The truth: we need migration.

The problem: too many politicians are terrified to say it.

Why? They're led by a) toxicity of the charlatans & b) wealthy media organisations who demand these useful distractions rather than us talking about inequality.

Reject it. Draw the line.

Sorry, but disagree with @hausfath.bsky.social here. You open Pandora's box, you ain't closing it again. We've already seen with Paris that well intentioned international agreements do not translate into physical reality and SRM governance is a much harder problem. Zero is the only safe level. /1

I have a new @nytimes.com guest essay w/ @davidkeith.bsky.social about sunlight reflection. We note its not a solution for climate change and at best a band aid to treat systems, and suggest if its ever done it should only be to replace the cooling from air pollution today:

Opinion | A Responsible Way to Cool the Planet

A small, carefully scaled geoengineering program could compensate for the loss of cooling as we eliminate sulfur pollution.

WTF??. I've only just appreciated this applies to *existing* visas. The US is effectively expelling its foreign non-naturalized scientists.

No scientist can reasonably avoid any travel - for work, and (heaven forbid) to see family. And 100k is beyond the means of pretty much everyone.

Gergely Orosz @gergely.pragmaticengineer.com · 19d

Those on an H1B cannot return to the US from tomorrow (Sunday) unless paying $100K. This is an out-of-the blue presidential action. We’ll see software engineers stranded abroad.

One easy to predict outcome: those on US visas will travel less… for work, for conferences etc.

To stop Reform in their tracks and challenge this failing Labour government - we need to grow our team of MPs.

We're planning to have brilliant candidates across England & Wales.

Never been involved with politics before? That's fine. Often even ideal!

Some awesome news here in NM this week. We became the first state in the country to guarantee free, UNIVERSAL childcare for ALL families! And, our Creamland Dairy workers and Teamsters Local 492 reached a labor deal ending their strike!

This is what pro-family, pro-worker policies look like!

This is a fascinating development.

Lawyers: Does DOE dissolving the climate report research group and declaring the lawsuits "moot" imply that the report cannot be used as the basis for any future lawmaking? Is there also responsbility for damage from misinformation? www.law.cornell.edu/wex/moot

The department said the end of the Climate Working Group means environmental groups' complaint over alleged Federal Advisory Committee Act violations is no longer valid.

Gavin Schmidt @climateofgavin.bsky.social · 28d

Online chatter suggests that the DOE Climate Change (Denying) Working Group has been disbanded and the report will be withdrawn. 😂

Seems that violating FACA and the Information Quality Acts have consequences.

Not seen any official announcement though.

Exactly… I am the same and have pivoted to just writing the TL:DR of what I want to say -on- the slide (in v. big text on account of my other I/O problem!). People who expect me to hear a whole different set of spoken info are hilariously optimistic, imho.

Yes. But I guess there was a lot of computing time used at varying carbon intensities, if that’s where you’re going :)

I still can’t quite believe @benmsanderson.bsky.social managed to pull this grassroots MIP-thing off (with no funding and no workshop and no CMIP infrastructure). My contribution to this paper was tbh mostly reigning in numerous more outlandish ideas, but that’s a lot of emotional labour, y’all.
