Oceans Will Solve Global Warming

From Prensa Latina:
A California University study suggests that oceans will solve global warming in the long term, Science magazine published in its latest issue.

Experts say the carbon dioxide (CO2) that comes from fossil fuels will be absorbed by oceans and that will eradicate the problem of global warming.

However, the problem with that long process is that it will take a thousand centuries to be completed, as happened with the last warming this planet went through 55 million years ago.

The scientific hypothesis is based on the analysis of marine sediments deposited during the global warming called Paleocene-Eocene Thermal Maximum (PETM).

The sediments reveal an abrupt change in the chemical composition of the sea, which started to develop at the beginning of the PETM, a period followed by a long and slow recovery.

US university Earth Science teacher James Zachos explained that when investigating the ocean´s sedimentary layers, he was able to observe the effects of a quick acidification during the PETM.

According to the teacher, the CO2 dissolved in the water creates that acidification to expand to the ocean´s bottom.

The latest research confirms that nearly half the CO2 produced by man (some 1.2 billion carbon tons) went to the oceans in the last two centuries.
I maintain that global warming is cyclical and the earth will take care of itself...and it appears that there is some scientific proof that this has happened before...
