Earth Sciences & Geology - July 2007

How do the Earth's poles reverse? I've heard that there have been 5 pole reversals since its beginning, but how did they happen? Does it take a large event to take place to make this happen? How does its field collapse? Is it a shift in potential, or does it just ware away after a while, or what? I can't find anything that explains it.

Hi,
I would like to know how much C02 gaz was produced and released in the athmosphere by human (industrial) activities in a recent year, in gigatons ?

I would like to know also how much co2 was released in the same period of time by natural phenomenon (volcanoes, sea, biomass....)

Please quote your source.

Thanks,
Cyril
