As a long-time listener of the Mindscape podcast, my respect and admiration for physicist / natural philosopher @seanmcarroll.bsky.social has only grown after reading this story about three prominent scientists who said no to Epstein.

#Drafts are now a thing on #Bluesky ! 🎉

EREVs (Extended Range Electric Vehicles) use a generator to to recharge the battery and extend range. They are rapidly growing their market share in China, and may soon do the same in other countries. #EREVs #PHEV #ElectricVehicles #EVs

"On top of threats of tariffs, port fees and visa restrictions on crews, the U.S. said it would also look at “sanctions on officials sponsoring activist-driven climate policies.”"

Colleagues in ocean science academia: 🧪🦑🌎 I am working on the section of my marine biology career advice book about applying to graduate school. I have lots to say here from both my own experience and years of teaching this stuff, but I’d welcome your input on any or all of this if you’re willing.

Statistics on how scientists feel about their presence on Bluesky versus Twitter. My personal experience (before closing my Twitter account in August 2023) was that engagement for my tweets had dropped to close to zero. No longer worth the effort... #Bluesky #Twitter #X #socialmedia

If you live in Atlantic Canada and were forced to relocate due to climate risks such as flooding, fire, sea-level rise or coastal erosion, a Dalhousie University researcher would like to talk to you and learn about what you went through emotionally and financially. www.cbc.ca/news/canada/...

Library and Archives Canada is now on Bluesky. Give them a follow! #Canada #CanadaSky @library-archives.canada.ca

Yep! 💯#SciComm

CBC Radio's science show 'Quirks & Quarks' celebrated its 50-year anniversary in a fun episode that invited experts to discuss the last 50 years of research in cosmology, genetics, climate, computers, agriculture and speculate on the next 50 years! 🧪 www.cbc.ca/listen/live-... #SciComm #Science

The Saxby Gale severely hit Atlantic Canada on October 4 & 5, 1869. On the 150th anniversary of this storm, @ryansnoddon.bsky.social wrote a nice summary of its evolution and impacts, including major flooding between Amherst and Sackville. www.cbc.ca/news/canada/... #SaxbyGale #stormsurge

This can't be good: "Over the past three years, leading tech firms have committed more toward AI data centers, plus chips and energy, than it cost to build the interstate highway system over four decades, when adjusted for inflation." www.wsj.com/tech/ai/ai-b...

Map projections make compromises between accurately representing either area, angles, or distances. Tissot indicatrices (blue circles & ellipses) inform us visually about map distortions. Standard parallels here are at 50°N and 70°N for the Albers and Lambert projections. 🧪 #maps #mapping #Canada

For Canadians who contemplate migrating their web hosting to servers physically located in Canada and subject to Canadian laws, hesitate no more! It's easier and faster than you might think. I did it this spring! Listen to this @ambermac.bsky.social interview with Emil Falcon, CEO of @whc.ca.

Always interesting to see how successive El Niño events and La Niña events modulate the global warming time series. The 1997-1998, 2015-2016, 2018-2019 and 2023-2024 El Niño events are easily detectable as bumps in this graphic from @copernicusecmwf.bsky.social. #ECMWF #GlobalWarming #ENSO #ElNiño

I know that job situations have likely changed for many in climate research. If you are looking for a new opportunity, maybe consider our current opening for the Chief Editor at Nature Geoscience. www.nature.com/naturecareer...

100 years of June sea surface temperature anomalies updated through 2025. Note the long-term warming (climate change) and other patterns of variability (e.g., El Niño/La Niña). Our oceans are accumulating a lot of excess heat! Data from NOAA ERSSTv5 at psl.noaa.gov/data/gridded...

I'd like to introduce a new page on my website: U.S. climate indicator visuals (zacklabe.com/united-state...). I only have a few basic variables so far, but I will be expanding this summer to add a range of metrics (e.g., ecological). I welcome suggestions! Hope this is useful, especially nowadays.

Would be neat if we could stop letting pundits from either side of the aisle lead the conversations in whatever direction they want it to go. Let the experts in weather measurement, forecasting, and emergency management speak and lead the assessment of this tragedy.

A large part of the western North Slope of Alaska with official forecast high temps over 90F today and tomorrow. This is borderline unprecedented if it happens. There are no weather stations in those 90F+ forecast areas though. So verification will basically be impossible. @alaskawx.bsky.social

Weather apps on our smartphones appear kind of magic! But formidable international observations, data exchange, and forecasting infrastructures are behind this "magic". 🧪 wmo.int/media/magazi... #weather #weatherforecast #wx

For Canada Day, I am proud to announce I migrated my website to a web hosting company owned and headquartered in #Canada: @whc.ca. I took advantage of the move to redesign my trilingual (English, French, Spanish) website using WordPress, a new skill for me. #CanadaDay denis-gilbert.ca/en/home/

A huge blow was dealt to hurricane forecasters this week as a critical tool was abruptly terminated by the Department of Defense and NOAA. The immediate discontinuation of data from three weather satellites will severely impact hurricane forecasts this season and beyond. More ⬇️

For anyone near a hurricane-prone area, this is alarmingly bad news. www.local10.com/weather/hurr... [1/5]
