How does oxygen get from the ocean surface layer to the ocean's intermediate depth and bottom waters? 🧪🌊 I wrote a brief overview of the processes involved and the key regions of ocean ventilation: denis-gilbert.ca/en/2025/04/1... #ocean #oceanography #oxygen #popularscience #science

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]

Interesting development about putting in place "boundaries" for the presently uncontrolled Web content scraping by AI models. #AI #CreativeCommons

🧪 Why having global environmental data (i.e including places sparsely populated) is important? Because weather forecasts improve everywhere including near populated centers. www.un-soff.org/news/ecmwf-e...

That's terrible news to read. For us documenting #SeaIce, having colleagues that share comparable data obtained by different algorithms is a form of quality assessment of our own data. It is a terrible loss for us as it is for our whole user community. @eumetsat.int @nsidc.bsky.social

Don’t call them tariffs. Call them import taxes.

NEW: NOAA operations slowed by mandate for Commerce Secretary to approve ALL contracts/contract extensions above $100,000. This nearly led to a significant deterioration of Nat'l Weather Service operations last night. www.axios.com/2025/04/01/n...

In early 2016, before #Trump won his first Republican presidential nomination, a prescient book by @shawnotto.bsky.social described three components of the war on #science. 1) Industrial 2) Religious/Ideological 3) Identity Politics Here's my review of Otto's book denisgilbert.com/blog/f/war-o...

Did you know there was water rationing in Bogotá last year? That's how bad drought has been. South America is being hit hard by the climate crisis but it rarely makes the news in US/Canada. I was quoted in this article about climate impacts in South America. nearshoreamericas.com/year-of-drou...

Elon was the one who switched sides and aligned with the enemy—that’s the definition of a traitor. Mark has been on Team America his entire life. And I know this because I’ve known him my entire life.

Democracy dies in primer… #bezos

After subscribing to the #WashingtonPost for seven years, I cancelled my subscription. For me what moved the needle beyond the "no repair zone" was #Bezos 's recent heavy-handed decision to control content in the Opinions columns. This caused another resignation today. www.npr.org/2025/03/10/n...

During the December 2024 - February 2025 winter more than half the days had new record low sea ice cover, including 26 of 28 days in February. @alaskawx.bsky.social #Arctic #seaice #globalwarming From Rick Thoman's winter 2024-2025 Arctic climate review: alaskaclimate.substack.com/p/winter-202...

Arctic 50-year average temperature change for winter, updated to include 2024-25. Warming in excess of 11ºC (!) in the Barents Sea and Svalbard areas due to mid-winter sea ice loss. No warming since the mid-1970s in eastern Siberia and parts of Greenland. Data from ERA5. #Arctic #ClimateChange
