Global CO2 Levels Pass A Dismal Milestone

Illustration for article titled Global CO2 Levels Pass A Dismal Milestone

Results published this week by NOAA indicate that the monthly global average concentration of CO2 surpassed 400 parts per million in March 2015—the first time since recordkeeping began in 1959 that the monthly average has exceeded that level worldwide.

Said Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network, in a statement:

It was only a matter of time that we would average 400 parts per million globally... We first reported 400 ppm when all of our Arctic sites reached that value in the spring of 2012. In 2013 the record at NOAA’s Mauna Loa Observatory first crossed the 400 ppm threshold. Reaching 400 parts per million as a global average is a significant milestone.

This marks the fact that humans burning fossil fuels have caused global carbon dioxide concentrations to rise more than 120 parts per million since pre-industrial times... Half of that rise has occurred since 1980.

DISCUSSION

Kip Russell: Has Spacesuit, will babble

Meanwhile, GOP assclowns are leading the pack that did this:

Last week, the House Science, Space, and Technology Committee, headed by Texas Republican Lamar Smith, approved a bill that would slash at least three hundred million dollars from NASA’s earth-science budget. “Earth science, of course, includes climate science,” Representative Eddie Bernice Johnson, a Texas Democrat who is also on the committee, noted. (Smith said that the White House’s NASA budget request favored the earth sciences “at the expense of the other science divisions and human and robotic space exploration.”) Johnson tried to get the cuts eliminated from the bill, but her proposed amendment was rejected. Defunding NASA’s earth-science program takes willed ignorance one giant leap further. It means that not only will climate studies be ignored; some potentially useful data won’t even be collected.

Great, so, you underfund the people reporting the bad news, so there’ll be no more bad news, and you can now LEGITIMATELY MAKE POLICY FROM IGNORANCE, BECAUSE THERE’S NO RESEARCH AND DATA CRUNCHING GOING ON!!!

You’re learning lessons from Canada, where our Prime Minister has been gutting science spending and destroying science libraries, and killing our long-form census, so they can go on their gut prejudices instead of having “nasty, nasty datases” that contradicts you.

Fuck.
