In 1958, Charles Keeling began measuring the the concentration of atmospheric carbon dioxide. Decades later, scientists at the Mauna Loa Observatory are still measuring, creating “the world’s longest unbroken record” of that data. They’re the ones responsible for the upkeep of this famous graph:
It must be kind of terrifying to track carbon concentrations on a daily basis as they tick slowly upwards. And sometimes when you’re watching something depressing, you just have to share it. So the Scripps Institution of Oceanography, which is in charge of the research, is posting the daily measurements on Twitter, so we can see the concentrations rise and fall with the seasons — while, over the course of years, getting worse and worse and worse.
Here’s yesterday’s measure for instance:

And, yah, that’s too high. Man, this is the most depressing Twitter account ever. I miss Shit My Dad Says.
