Extracting carbon from nature can aid climate but will be costly: U.N.

OSLO (Reuters) - A little-known technology that may be able to take the equivalent of China's greenhouse gas emissions out of the carbon cycle could be the radical policy shift needed to slow climate change this century, a draft U.N. report shows.

Using the technology, power plants would burn biomass - wood, wood pellets, or plant waste like from sugar cane - to generate electricity while the carbon dioxide in the biomass is extracted, piped away and buried deep underground.

Among techniques, a chemical process can strip carbon dioxide from the flue gases from combustion.

The process - called bio-energy with carbon capture and storage (BECCS) - would make the power plants not only carbon-neutral but actively a part of extracting carbon dioxide from a natural cycle of plant growth and decay.

The technology could be twinned in coming decades with planting forests that absorb carbon as they grow, according to the study obtained by Reuters.

It would be a big shift from efforts to fight global warming mainly by cutting emissions of greenhouse gases from mankind's use of fossil fuels in factories, power plants and cars, but may be necessary given the failure so far to cut rising emissions.

Their 4% CO2 output is killing Gaia.

Then freeze-dry them, and the carbon sequestered in the remains can be pounded into a powder and dumped into a played-out coal mine.

Easy-peasy.

Good thinkin’!

I wonder how long it takes before they start forbidding the cremation of human remains.
