Underrated? A little. Essential? Absolutely. The Brazil Current is the South Atlantic's western boundary current, carrying warm water southward and driving circulation across an entire ocean basin. It doesn't have Gulf Stream's PR team, but WHOI scientists know it's doing the same critical work.

"The period over which a tripling of research publications has occurred ... is also a period of convulsive media change... Simply put, even as there are more scientific papers than ever, there are fewer journalists covering science." 🧪 From @chriscmooney.bsky.social:

How ‘mega-science’ helps explain the plight of science communicators right now

How do we communicate about -- or as journalists, cover -- 3.5 million scientific studies per year?

Friday ice update - #Arctic sea ice extent is currently the 2nd lowest on record (JAXA data) • about 390,000 km² below the 2010s mean • about 980,000 km² below the 2000s mean • about 1,430,000 km² below the 1990s mean • about 1,970,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i...

Line graph time series of 2026's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2025. 2026 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and March by looking at the decadal average line positions.

I can't get over this number: in 2007, there were 360,000 newspaper jobs. Now, there are 80,000. "My local paper sucked!" Sure. What sucks even more? The void. "I get all my news from the Guardian!" No, the Guardian doesn't report on your town council, your school board, local cops.

I was told today my Washington Post job is being eliminated It's just a job, but it's one that I was proud to do for 8+ yrs alongside the best in the business I'm here for opportunities to tell stories about the natural world and how we impact it dino.grandoni@gmail.com

2025 was an exceptional year for the Earth's climate ⬆️ Warmest ocean heat content ⬆️ Tied as second warmest surface temps ⬆️ Second warmest troposphere ⬆️ Record high sea level and GHGs ⬇️ Record low winter Arctic ice New State of the Climate over at Carbon Brief: www.carbonbrief.org/...

Most 2025 global temperatures are now out (degrees C above 1850-1900 baseline) 1.41 HadCRUT5 1.44 Berkeley 1.46 JRA-3Q 1.47 Copernicus 1.53 DCENT-I NOAA and NASA GISS values will be public at 2pm UK time and but based on already public Jan-Nov data they will likely be between 1.3 and 1.4 degC.

Multi-dataset comparison of global temperatures from 1850-2025, with 2025 values highlighted in a separate panel for each individual dataset. Baseline is a combination of 1850-1900 means.
