How the big polluters send CO2 swirling round the world
NASA has released the video above, showing a dramatic visualisation of how carbon dioxide enters the atmosphere and quickly travels around the globe.
Striking is the extreme difference between carbon dioxide levels in the northern and southern hemispheres and the dramatic change in global carbon dioxide concentrations according to seasons, which NASA attributes to the growth cycle of plants and trees changes.
The 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.
It 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
