Oh good. Underestimating La Niña in climate models also means we'll underestimate rapid intensification potential (not that climate models are great at top-category storms anyway)

Have you wondered about trends & ENSO variability in Atlantic TC intensity/intensification? @scamargo.bsky.social and I did. journals.ametsoc.org/view/journal...

A great article by the @washingtonpost.com which I’m excited to have contributed to!💦💨 It has really powerful interactive visualisations of how a warming planet is also a moistening planet on which more precipitation-induced disasters strike regions all around the globe🌎 wapo.st/4oklfvh

New paper! Heat-pump water heaters could cut energy costs and pollution, but installs often require 💰 electrical work to accommodate backup resistance heat. My student Levi Premer developed prediction and control software to eliminate the need for backup heat and ⬆️ efficiency and flexibility. 🧵1/

The LA fires destroyed "approximately 9% of the number of new homes completed statewide in the prior year or more than 60% of the number of homes created in Los Angeles County in 2024" Building new homes to meet the housing crisis is crucial, but can't pour into a bucket with a gaping hole in it.

A fascinating read from Sullivan's Island, SC. A sea level adaptation & resilience plan has some people in a tizzy because of property rights and spending on public works projects. They had a chance to add input for over a year & waited until it was already drawn up before getting mad.

Thanks to BESS (Bluesky Every Skeet Storage) the dreaded posting Duck Curve is now a thing of the past.

So. This is a nice visualisation tool to play with! Both #ERA5 and @esaclimate.bsky.social datasets visualised for the whole world in a beautiful interface. It would be fantastic to see it updated for the last 10 years. #SciViz www.lexcube.org

#Melissa: Jamaica will receive an insurance payment of $70.8mn from its policy through the Caribbean Catastrophe Risk Insurance Facility (CCRIF); a record for the program. Combined with the expected full $150mn payout from Jamaica's catastrophe bond, this will be important liquidity. (1/2)

ICYMI: Staggering rainfall in Vietnam in the past week. Bach Ma mountain near Hue City recorded a one-day rainfall of 1,740 mm (68.50 in). This is unofficially the second highest 24-hour rainfall ever recorded globally. Record: 1,825 mm / 71.85 in La Réunion; January 7-8, 1966 (1/2)

Two notes: The Southeast is where you can get a lot of decarb juice for the squeeze from the power grid: bsky.app/profile/kell... And that, as noted by the linked paper above, fossil fuel price *volatility* is one of the things making it expensive - exactly was happened w gas prices in Georgia.

Here are updated verifications for 2025, AL/EP combined, EMXI not available. Impressed that NHC is beating everything, including consensus, for intensity, and everything but Google DeepMind (GDMI) for track. Rough year for GFS and the statistical intensity aids. Banner year for GDMI.

Inspired by Brian's chart, I investigated how much time North Atlantic named storms spent at hurricane and at major hurricane strength during 1966-2025. Blue = proportion for "hurricane time" (category 1-5). Orange = proportion for "major hurricane time" (category 3-5). More details in alt text!

A nearly one-week animation for Hurricane Melissa with infrared (IR) imagery on the left and its maximum wind speed (intensity) evolution on the right. The animation briefly pauses at landfall in Jamaica. IR images extend about 600 km from the center of the storm to illustrate its shape evolution.

The ratio of major hurricanes to named storms is an interesting one... a kind of "quality-over-quantity" index. Here is what that percentage looks like over the past fifty years, and note the average is 21%. More at bmcnoldy.blogspot.com/2025/10/afte...

i don’t know how to cross-post this from FB but this is absolutely heartbreaking. The age of scientific ocean discovery we were brought up in is gone & will never come back. I can’t.

This is really touching. Mark Easter, who wrote a book about regenerative ag and disagrees with me about some fundamental stuff, went out of his way to emphasize a bunch of things he admired about my book before getting to his polite disagreement. yaleclimateconnections.org/2025/10/the-...

After Hurricane Beryl devastated Jamaica’s grid last year, officials at the island’s sole utility vowed to fortify it. But the company’s initiatives were only in the planning + early implementation stages when Hurricane Melissa hit. Story @bloomberg.com, gift link: www.bloomberg.com/news/article...

Here are all the Category 5 segments of the 45 known Cat 5 Atlantic Basin hurricanes since 1924, with Melissa's 36-hour segment highlighted.

Remember when social media was a useful tool for assessing damage post-disaster, instead of having to fish through fake photos made with AI garbage? That was nice.

Just joined and already seeing some great discussions over the climate crisis from some wonderfully insightful voices! I'm a research assistant working with @fisherdanar.bsky.social @au-cece.bsky.social, it's been a blast. Finishing my MA in Environmental Policy with a focus on water governance.

Given higher than usual confidence of rapid intensification (RI) from analyses of an exceptionally favorable environment & with the aid of newer hurricane models (HAFS) & Google DeepMind, NHC was able to skillfully predict Melissa's RI days in advance.

Installed sensors at Teakettle this weekend. I broke down 5 times. The District Ranger requested that I tell ‘the truth’ about the fire and the forest. Here you go…

This is heartbreaking & heartwarming in equal measure. The courage and kindness of many of my fellow Americans has been sustaining these past few months. www.nytimes.com/2025/10/28/c...

Just realizing I've posted some version of this thread at least a couple times over the years to defend adaptation when it gets thrown out with the adaptation bro bathwater. And likely will again.

#Melissa has made landfall in #Jamaica, and has preliminarily tied the record for the lowest pressure of any landfalling hurricane in Atlantic history: 892 mb. That was last observed 90 years ago with the 1935 Labor Day hurricane. The storm does not look like it even notices Jamaica being there.

But they captured some historic data including the 893mb center drop, cementing #Melissa as the 3rd most intense hurricane on record in the Atlantic. Mission for the ages.

I was worried for my crew mates when I saw them circling in the eye for over 20 mins. Looks like the very rough ride was confirmed. Plane had to leave early. They reported svr turb and a "sawtooth" eye. Looks like they moved 600-700ft up & down during this stretch in ~1 min.

You VERY rarely ever see a satellite presentation like this anywhere in the world. And you certainly don't expect to see it this close to a mountainous island. As of 5am EDT on Tuesday, #Melissa is the 8th strongest Atlantic hurricane on record by central pressure (901 mb).

It's the beef.

If you read my stuff often, you'll probably detect a shift in tone tonight. It felt weird writing it. Truly hoping for the best but my goodness this is bad.

October 27 PM: Here is the updated Atlantic record book for most intense hurricanes in NOAA's official dataset going back to 1851. Melissa has rocketed up the list(s). In the past 72 hours, Melissa has seen: - Sustained winds increase by 100 knots (115 mph) - Minimum pressure drop by 91 millibars

Current #Melissa eye diameter of 10nm & 45km wide hurricane force winds projected along current track wouldn't bring much wind impact to Kingston (SE Jamaica). So any eyewall replacement and widening of the storm could bring Kingston into play. But the surge is another beast altogether...

Carbon neutrality doesn’t always lead to decarbonization. But who is decarbonizing? We looked at >600 US colleges and universities and found 7 that have decarbonized direct (Scope 1) emissions by at least 50% (usually with ground source heat pump networks). This is possible folks! 1/6
