The most iconic figure in the environmental sciences is the Keeling Curve, the CO₂ record from Mauna Loa, Hawaii.
NOAA had a wonderful site where you could visualize and download these data, and now it's just gone. These data belong to us and we should not let this happen!
@davidho The first data handling exercise that I ever taught Environmental Science students at Lancaster University involved downloading and plotting the Keeling Curve. We were at about 370 ppm then. 
There's still the "graph dashboard" in case you still want students to download and play with global CO2

Scripps has Mauna Loa, Barrow, LA, and South Pole.
The website gml.noaa is back online. Apparently it was a planned power outage yesterday ^^ Just when the DOGE kids came...
Should be adopted by all agencies, I think: just schedule a power outage when they come.
The NOAA Keeling Curve data page is back online:

@davidho 
Those fascist morons want to break the thermometer to hide the fever.
We cannot access this dataset any more.
@davidho W T F ... ? What is the legal basis for this?
@chromatic @ibrahim_cris @davidho And people still think they can wait and sit it out. They now have the power over money and, above all, information. There is no ‘nice’ way out.
@chromatic @davidho
Yes but... why did nobody in Us call judge and done that it stuff to do "law and order"? I think that some it stuff do not hide the truth well. They could personalize it to trump only or merge the web to a torrent url... still do not get it.
@davidho Well we all know if we can't see it, then it doesn't exist right?

> NOAA had a wonderful site where you could visualize and download these data, and now it's just gone.
so.. nobody did download it?
@bonifartius @davidho There are lots of copies. But it is the original and was kept up to date.
I hope they keep up the measurements with the same methods. Perhaps writing the values down in a little black notebook hidden behind a file drawer…. Otherwise we would loose a continuous record.
There are many places on earth where these measurements are made. But this is (one of?) the oldest and it it far away from industrial areas, sitting in the ocean.
@davidho the whole subdomain gml.noaa.gov seems offline, not just that data. Hopefully it's just a fault....

@davidho gml.noaa.gov is back again - is that data still there?
@davidho I read it first as Moana Loa 
@davidho If you’re truly concerned, show up. Meet us at the capital today from 12–4 PM. Silence is obedience. #5050Protest
@davidho Is this part of the "climate problems don't exist anymore" US presidential decrete?
@davidho 2025-2-5 10:50 am EST: http://gml.noaa.gov is still not responding to hyperspin.com.
Has "Big Brother" already started using the memory hole?
@davidho I first saw this graph around 1980 in a practice test for a science exam. It wasn't part of the curriculum as such, but it made a good real-world test of data comprehension and interpretation.
I looked at it and thought, "Holy shit, we are in trouble".
@davidho They tell on themselves with this. It shows they don't believe the facts on their side, so they will bury all facts.
But of course, that's part of fascism: truth doesn't matter, only power.
@davidho
Horrible. If the sadist-fascist coup doesn't let US data collections go back online after they wanked enough over making them disappear,
I only know where to get the European GHG measurements:
at ICOS.
@davidho I was surprised when I checked yesterday and found NASA's GISTEMP data was still online. Of course, there's no knowing how long that will continue to be true.
@davidho In case this is useful to anyone: this specific dataset is also hosted by UC San Diego, and their site is still up: https://keelingcurve.ucsd.edu/
None of which makes the broader problem any less alarming, but at least this individual dataset has a backup.
@davidho Turns out that this one is less worrisome. Multiple sources confirmed that it's due to a planned power outage at the David Skaggs Research Center that hosts the website. More info:
