In celebration of the end of Fake Breakup, it snowed today like crazy. Which led to my first tweet of the day, referencing climate change deniers. A later tweet about today’s Mudflats post on Sen. Mark Begich also has to do with climate change and, specifically, carbon dioxide levels in the atmosphere. So I thought I’d head up this Daily Tweet post with a video I came across recently that visually depicts the changes in atmospheric CO2 levels over the past 40 years.
I found the video on the 18 Feb 2010 post on “Visual depictions of CO2 levels and CO2 emissions” at the website Skeptical Science. As stated there,
Measurements of atmospheric carbon dioxide come from more than a single station on a Hawaiian volcano. There are ground based stations scattered across the globe taking direct measurements. Three independent satellites take global CO2 measurements: the Atmospheric Infrared Sounder (AIRS) on the NASA Aqua spacecraft, Envirosat by the European Space Agency and IBUKI by the Japan Aerospace Exploration Agency. For periods before direct measurements, CO2 can be determined from Antarctic and Greenland ice cores. Here are some visual summaries of CO2 data:
This first video shows surface measurements of CO2 varying over different latitudes from 1979 to 2006. The graph is created by Andy Jacobson from the NOAA. It’s packed with information – there’s a global map displaying where the measurements are coming from, a comparison of Mauna Loa CO2 to South Pole CO2 and the graph expands at the end to include ice core measurements back to the 19th Century.
There are a number of other videos giving visual depictions of CO2 levels, too. Deny that, deniers.
And now here’s the tweets.
