In other words it’s been an incredible winter for Syracusans ❄️😍

💡 New paper alert! For me, the use of AI in climate science is exciting and has so much potential, but I worry that it risks taking away the best part of studying atmospheric science: understanding how our complex ocean and atmosphere system works dynamically.

Second snowiest day on record!!!???

Need everyone to know that yesterday was the snowiest Syracuse calendar day since the Storm of the Century in 1993! Snowiest day in my life 😍

In case you’re wondering what I was just up to 😍

Spot the lake effect snow band

This map is great because, yes, while the Northeast has been colder than usual this December, the west has been on fire. The magnitude of the anomalies aren’t even close— it’s way hotter out west than it is cooler in the Northeast compared to normal

What’s the relationship between winter weather & climate change? It starts with the polar vortex. UCS's @marc-alessi.bsky.social breaks it down for you. This holiday season, show some love to your local meteorologists and support science and scientific funding.

Still thinking about that squall line from this morning 😍

Happening today at #AGU25 #SaveNCAR

The dismantling of NCAR should be the trending story on Bluesky, not the fucking Oscars leaving ABC for YouTube.

🚨 Late breaking update! 🚨 We'll be joined by @neguse.house.gov, who will be giving brief remarks on news of threats to NCAR during this #AGU25 session at 5:30 CT in E-2. Join us!

The Trump admin intends to dismantle the National Science Foundation National Center for Atmospheric Research (NCAR), one of the US' leading weather and climate research institutions. We must urge Congress to halt this dangerous action immediately. 🔗Take action: act.ucsusa.org/4oWtCwz

Devastating and dangerous blow to the weather and climate community tonight, as 20,000 earth and space scientists meet at #AGU25. New @ucs.org statement from @carlonimbus.bsky.social on the Trump administration plans to dismantle @ncar-ucar.bsky.social: www.ucs.org/about/news/t...

This past week, we released a map detailing the Trump admin's legally dubious Clean Air Act exemptions for coal plants, chemical manufacturers & other facilities emitting toxic air pollutants. These exemptions will harm overburdened communities across the US. Here's how this interactive tool works:

The sweater I’m wearing tomorrow to fly to AGU 😍🌧️⛰️

Consider signing up for this exciting hybrid workshop on Climate and AI in January! I'm excited to speak on one of the panels with @eabarnes.bsky.social and Amelia Cook, moderated by Katie Dagon www.nationalacademies.org/projects/DEP...

Heading to AGU next week? Check out our session on Monday!

So incredibly proud of the @wclivestream.bsky.social team. And I am deeply grateful to work at such an incredible organization that supported me in this effort. Please continue to support science and scientific funding!!

Why were there fewer hurricanes than usual in 2025? And why were they so strong? Could 2025 be just an abnormal year, or was 2025 a glimpse of future hurricane seasons more significantly influenced by fossil fuel-caused #ClimateChange? @marc-alessi.bsky.social breaks it down: bit.ly/3MsiZUR

We saw less hurricanes than usual in 2025, but the ones that did form were incredibly powerful. Is this a glimpse of what we might expect in future hurricane seasons? I wrote down some thoughts here! blog.ucs.org/marc-alessi/...

The Trump administration has removed scientific data and climate change information from US Environmental Protection Agency (EPA) webpages, including all references to human activities driving climate change.

Copernicus just released its November numbers: 2025 is on track to be one of the top 3 warmest years on record. The Jan-Nov period ties 2023 for the second warmest ever.

Next week at #AGU25. GC14C-06, Monday at 5:10.

This is absolutely awful. This was one of the best resources for climate indicators data, and my go-to share for help answering public questions. Luckily I captured some of them on my new U.S. climate page a few months ago: zacklabe.com/united-state...

It got down to -22F at Saranac Lake Airport last night 🧊

Thursday night temps 👀👀👀

Was checking out the snowfall totals on CoCoRaHS from the lake effect event on Friday... I didn't realize that some locations got over a foot in Madison and Oneida counties! I ended up with about 8 inches in the city of Syracuse

Not the fossil fuel companies that correctly predicted climate change with their own climate models in the 1980s, and then started to spread disinformation in the 90s to profit off their known destruction of the planet, right?

The US dodged a bullet this year with no direct hit by a hurricane… especially during the government shutdown. Huge props to the forecasters at the NHC who worked without pay (and the hurricane hunters!)

We even got that Georgian Bay connection today 😍

Please consider reading this beautifully-written and timely blog post by my colleague: blog.ucs.org/erika-spange...

So cool: northerly wind at the surface bringing in lake effect snow from Lake Ontario, and southerly wind higher up in the atmosphere bringing in snow from the south. Two different types of snow ❄️

So he’s… literally trying to starve Americans

From Dr. Rachel Cleetus: "Humans still have agency over this dire problem we have caused... The choices our political leaders make now — including at #COP30 — will determine the future we leave to our children and grandchildren... Global cooperation is absolutely essential to solve this challenge."

Why is this so funny 😭😭

Wore my rejecting kings shirt to the gym today 😤 love feeling hopeful

It’s done! Dems flipped the legislature! First time in 50 years!! www.syracuse.com/politics/cny...

Dems are on track to flip the Onondaga County Legislature (where Syracuse, NY is). It was 12R-5D. Dems are currently up 10D-7R. That's 5 seats flipping in a 17 seat legislature! Don't overlook the local elections people!!

Just plotted the 58 METAR stations that are expected to stop reporting observations due to the FAA ending their contracts. Overlaid the counties in NC that issued a disaster declaration after Hurricane Helene last year.

😍😍😍😍😍❄️❄️❄️❄️❄️

Going to be a gusty Halloween evening for trick or treaters! 7pm ET forecast has gusts near 50 mph in Syracuse 🌬️

Some much needed rain working through CNY

Shockingly, because of the government shutdown, the hurricane hunters are going unpaid as they risk their lives for theise data. And staff at the National Hurricane Center are also without pay as they continue to perform their critical duties during this record-breaking storm.

The irony of not having access to your own journal article 😭

I hope you'll join me in canceling your Spotify subscription. Absolutely sickening stuff.

Melissa turning more northerly in the last few frames as it approaches Jamaica-- more of a wobble? Effects of the eyewall will reach Montego Bay shortly...

Ties for the strongest hurricane to ever make landfall in Atlantic recorded history. Unprecedented stuff for Jamaica.

Quoted here: "The role climate change has played in making Hurricane Melissa incredibly dangerous is undeniable." grist.org/extreme-weat...
