I showed my students this movie of how atmospheric #CarbonDioxide (CO₂) travels around the globe and you should see it too.

NASA Scientific Visualization Studio - A Year In The Life Of Earth’s CO2

Visualization - Jan. 1, 2006 - Dec. 31, 2006 North America - Feb. 1 - 28, 2006 Africa - Aug. 1 - 31, 2006 Himalayas - Feb. 1 - 28, 2006 Still image - Jan. 1, 2006 Still image - North America - Feb. 12, 2006 Visualization without annotation - Jan. 1, 2006 - Dec. 31, 2006 An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe.Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.

@davidho I'm confused about two things:
- Production in the northern hemisphere is mostly from November to June, i understand heating in winter certainly pollutes a lot, but I'm surprised that it would make that much difference, and that it would last as far as June, so that might be the wrong explanation.
- From July to October, not only production seems minimal, but global concentration as well, but as far as I understand, CO₂ doesn't go away nearly that fast.
@tshirtman @davidho I had the same questions. Things that could contribute:
- A huge portion of CO2 is absorbed by the oceans, but that probably takes time.
- The plants from the northern hemisphere take up a lot of CO2, but mainly in spring and summer.
Not sure how important these effects are.
