A hurricane bearing down on Hawaii prompted operators to shut down CO2 monitoring equipment at Mauna Loa Observatory on the Big Island.
CO2 levels increasing at a faster rate than before
Scripps Oceanography lab monitoring atmospheric CO2 named National Historic Chemical Landmark
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve.
The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve. [youtube https://www.youtube.com/watch?v=0Z8g-smE2sk&w=560&h=315]

The dips are generally caused by upslope winds that that are depleted in … Read More
