Rebecca Solnit Says the Left’s Next Hero Is Already Here

In my workshops I argue that stories are like hammers—we can use them to build houses or break kneecaps.

In new NYT profile @rebeccasolnit.bsky.social says,
“The idea that stories are these magical devices that will do all our work for us is, itself, a bad story.”

Bar graphs with blue, gray and red bars for each three month season. Graph shows the probabilities of La Nina, Neutral or El Nino. Blue bars biggest at start. Gray in the middle and Red by the summer 2026

Do forecasts suggest we're heading into an El Nino later this year? Yup!

Would an El Nino mean a surge in global temperatures? Yeah, most likely (on a ~6ish month lag)

Is climate change boosting the forecast ONI (not the RONI)? Uh Huh

Is it too early to talk El Nino strength? IMO, yes.

Graph of Nino3.4 sea surface temperature anomaly forecasts from the ECMWF model for the next 6 months. Red lines show temperature anomaly and they go up.

Seeing this ENSO forecast shared a bit. Let me put my ENSO hat on for a sec to say a couple things.
1. This uses a 1981-2010 climo which will boost the anomaly numbers.
2. This doesn't use the Relative Oceanic Nino index (RONI), which would slash these anomaly numbers by, my guess, 0.5C

The discrepancy between water year to date precipitation and snowpack at California's snow-monitoring (SNOTEL) stations is remarkable. Just 40% of the precipitation remains locked up as snowpack, the second-lowest percentage since 1981, amid above-normal temps and rainy-dominated storms this winter.

I haven't looked at how the atmosphere averaged over winter was set up, but I'd imagine a big ridge of high pressure out West and a trough out East.

Now why would the West see such a huge area with record-breaking heat, while the East was only sorta cold?

This winter is such a great example of shifting baselines. As someone in the east, it was cold this winter. Full stop. But it "felt" even more frigid because we haven't had such cold recently.

It was cold but not historically so. But good heavens look at that record-breaking heat out West. 🔥

Data Notice: NCEP/NCAR Reanalysis 1 updates to end on or about March 9. Learn more:

Data Notice: NCEP/NCAR Reanalysis 1 updates to end

The National Weather Service's National Centers for Environmental Prediction (NCEP) Central Operations has announced that the Climate Data Assimilation System (CDAS) will be discontinued in favor of the Conventional Observation Reanalysis ( CORe) effective on or about March 9, 2026.
What this means

Because of this change, PSL will no longer be able to update NCEP/NCAR Reanalysis 1 starting around March 9, 2026, The exact date is pending the discontinuation of CDAS by the National Weather Service.

The historical NCEP/NCAR Reanalysis 1 data will remain available on our site.

We are in the process of identifying other products that may no longer be able to be updated or will require a suitable alternative to CDAS to continue operating.

And yet another long standing weather and climate dataset to be terminated. While other reanalyses provide higher resolution data, none are available in as close to real-time (lag ~36 hours) as R1. #weather #climate @wxmanms1.bsky.social

Not gone? Climate change. That's still around and getting worse.

But also not gone from that fight? Me

If the last year taught me anything, it's the power of people and community to fight for what's right.

Here's to a better year.

It's a weird day. Today marks the one-year anniversary of my illegal firing from NOAA. And what a year it has been.

In the last year, I've seen pretty much my entire 15 year NOAA career attacked.

Climate coverage is shrinking. We're expanding it. Announcing a new weekly video podcast!

the epidemic of men launching podcasts about nothing has gotten out of control

to combat this I am launching a podcast WITH A WOMAN (veteran climate journalist Tracy Wholf) to talk about stuff that actually matters (the planet being destroyed by the worst people alive)

The southern region was impacted by an atmospheric river that gained additional moisture by passing over a marine heatwave in the Atlantic.

Our colleagues at @climatecentral.org found that this marine heatwave was made 10x more likely by climate change. 4/5

This storm is forecast for tomorrow night into Monday. And the range of snowfall totals for the DC area from @nws.noaa.gov is 0.5 to 10 inches. I don't think I can remember a winter storm this close to happening with such uncertainty.

Map of major West African cacao-growing regions titled “Extreme Heat and Cocoa.” Shaded areas across Côte d’Ivoire, Ghana, Nigeria, and Cameroon show additional days above 90°F in 2024 linked to climate change. Darkest red areas indicate 60–70+ extra hot days added in key cocoa-growing zones. Bar chart titled “Heat Hurting Chocolate: Average annual days above 90°F (2015–2024).” Côte d’Ivoire averages about 80 days above 90°F per year, Ghana over 100 days, Nigeria around 70 days, and Cameroon about 30 days. A shaded portion of each bar shows a significant share of those hot days were added by climate change.

🍫 Human-caused warming is bringing more extreme heat to West Africa, which produces 70% of the world’s cocoa, the key ingredient in chocolate.

In growing regions of Côte d’Ivoire & Ghana (over half of global supply), heat above 90°F now occurs ~40 more days per year on average.

Great to speak at the Price Forbes Aviation Forum in Bogota earlier this month. I discussed air turbulence and climate change. How bad can it get? Potentially quite bad, I think...
