“GIVING A F*** ABOUT CO2 SINCE 1958.” carbondoomsday.com Carbon Doomsday is a site on a mission — it wants to show you just how much carbon dioxide is in the Earth’s atmosphere, and it wants to make an impression in doing so. The year mentioned in the slogan references the source of the site’s data, which is taken from daily readings gathered by scientists at the Earth System Research Laboratory (ESRL) in Hawaii since 1958. Carbon Doomsday then presents the information in a graph, clearly showing the cyclicallyfluctuating measurements of CO2 in the short-term (specifically, the seasonal cycle that makes up a year), but showing the overall trend of increase over the 5- and 60-year timeframes. Since the recording program began, the measurement has increased by close to 100 PPM (Parts Per Million), climbing from 313.04 to 410.07 PPM, and more than 20% of the increases over the entire 60-year span have occurred in the last 5 years. Beyond the doom and gloom, the site kindly tells you how you can “give a f*** about it” as well, with such links ranging in effort from sharing the chart on Twitter to volunteering to work for the project.
