Geo-engineering is the advanced process, and it encompasses various propositions and man-made schemes, that can tepidly or even radically alter the Earth’s own climate; and it is very real.
The National Academy of Sciences defined geo-engineering as:
“… options that would involve large-scale engineering of our environment in order to combat or counteract the effects of changes in atmospheric chemistry.”
Greenhouse gas remediation:
Such projects aspire to remove greenhouse gases from atmosphere directly or indirectly.
In this ingenious proposal, vertical ocean pipes would be utilized to mix cooler deep water and warmer surface water.
