CarbonTracker, a project of the U.S. government's National Oceanic & Atmospheric Administration's Earth System Research Laboratory, has produced a telling time-lapse video chart of CO2 (Carbon Dioxide) concentrations starting in January of 1979 and ending in January of 2011. Measurements were taken in dozens of locations around the world (the red ball measures CO2 in Hawaii and the blue dot measures CO2 at the South Pole)

A Nice video from FRAM - High North Research Centre for Climate and the Environment, on a project to measure albedo in Greenland., was spotted by my colleagues at IPF. Brings science in a very informative, clear, well shot and edited way, with good presenters:

"Snowpit studies provide a vital link between the modern atmosphere and the climate history reconstructed from ice cores. This video documents one of the types of measurements made in snowpits and explains how snow sampling informs ice core studies".

Its construction now complete, the science instrument that is the heart of NASA's Orbiting Carbon Observatory-2 (OCO-2) spacecraft -- NASA's first mission dedicated to studying atmospheric carbon dioxide -- has left its nest at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and has arrived at its integration and test site in Gilbert, Ariz.
