Global Atmospheric Carbon Dioxide

Global atmospheric carbon dioxide concentrations from Oct. 1 through Nov. 11, as recorded by NASA's Orbiting Carbon Observatory-2. Carbon dioxide concentrations are highest above northern Australia, southern Africa and eastern Brazil. Preliminary analysis of the African data shows the high levels there are largely driven by the burning of savannas and forests. Elevated carbon dioxide can also be seen above industrialized Northern Hemisphere regions in China, Europe and North America.

#AGU14 NASA’s Orbiting Carbon Observatory shows surprising CO2 emissions in Southern Hemisphere

The first global maps of atmospheric carbon dioxide from NASA’s new Orbiting Carbon Observatory-2 mission demonstrate its performance and promise, showing elevated carbon dioxide concentrations across the Southern Hemisphere from springtime biomass burning. At a media briefing today at the American Geophysical Union meeting in San Francisco, scientists from NASA’s Jet Propulsion Laboratory, Pasadena, California;…

Guest Post by Willis Eschenbach I greatly enjoy reading old science. Back fifty years or more ago, they actually did real science, not the “my model says it must be true” kind of thing that we are treated to today. In that regard, I’ve been fortunate to stumble on one of the earliest papers on…


A look at carbon dioxide vs. global temperature

Danley Wolfe writes: The piece below appeared in op-ed pages of many newspapers and online recently, released by by Agence-France-Presse (AFP) one of the largest news agencies in the world. I saw it in the Korean Herald, September 9, 2014 edition, and it appeared in most newspapers all over the world, including and especially developing…
