US Weather Agency to Preserve Research Websites in Reversal The US National Oceanic and Atmospheric Agency will preserve access to websites tied to its research division, after previously moving to cancel a cloud web services contract that supports many of its...

BREAKING: In a reversal, all NOAA Research sites will now remain online with "no interruption in service," according to the agency. NOAA had previously moved to cancel the research division's cloud services contract.

US Weather Agency Websites to Vanish Under Planned Contract Cuts The US National Oceanic and Atmospheric Agency is poised to eliminate most websites tied to its research division under plans for the cancellation of a cloud web services contract, a move that could s...

Almost all NOAA Research websites that rely on cloud services - including Amazon, Google and WordPress - are poised to disappear at midnight ET Saturday after a contract was targeted for "early termination." Labs may also feel the effects.

FYI Folks, for a while NOAA's Climate and Economic Justice Screening Tool was down. It's back up now! Everybody go check it out and then DOWNLOAD the data so that if/when NOAA resources continue to be gutted, we can still use that data.

The indigenous peoples of the PNW have stewarded waters of the Salish Sea since time immemorial and tribal leadership in Dungeness crab management (and research) continues to be critical

'Their loss diminishes us all': Scientists emphasize how Trump's mass NOAA layoffs endanger the world "From our perspective down in the trenches actually working for the government, it feels like the people up top just have no clue about anything."

"Making us less able to fight the biggest problem of the 21st century doesn't make anything more efficient and doesn't make anything great," Shiffman said.

To be clear, this is *academic survival* (which seems like an important distinction)

Lower survival rate among trainees in labs with highly productive mentors raises important concerns about what we value in academia. Many interesting things to stew over with this paper!
