BIOCHAR: A possible Game changer for mitigation and carbon dioxide removal (CDR) – as well as agricultural benefits!
Biochar is a way to enhance the soil, improve soil-moisture retention and sequester carbon from the atmosphere.
It is a solution to reducing the global impact of farming as well as utilize and in reduce and make use of agricultural waste.
Since biochar can sequester carbon in the soil for hundreds to thousands of years, it has received considerable interest as a potential tool to slow global warming.
The burning and natural decomposition of trees and agricultural matter contributes a large amount of CO2 released to the atmosphere. Instead, pyrolized Biochar can store this carbon in the ground in the form of charcoal and provide the microporous habitat for fungi and bacteria continue to pull carbon out of the atmosphere and thus aid in reducing atmospheric CO2 from the atmosphere.
At the same time its presence in the earth can improve water quality, increase soil fertility, raise agricultural productivity and reduce pressure on old-growth forests.
See links below on its history first discovered by the Amazonians and more recently by the Japanese (seeking links for the latter).

Biochar seems to be presently popular as a soil enhancer; NOT FULLY APPRECIATED is its sequestering capabilities. Please read the following 2 articles (more might be added later) and disseminate/thanks:

Excerpts from the International Biochar conference video highlighting Cool Planet link: YouTube;
Latest: Reduce atmospheric CO2 by 100ppm in 40 years?
Promise for the future regarding agriculture and sequestering Carbon (with a potential claim of 100 ppm in 40 years) – as told at a recent CRES/Biochar meeting on 6/26/2014; see:

CARBON NEGATIVE BENEFITS: YouTube Link above to where Cool Planet makes claims of diagram below at 18:30″ (click here); go to ~8:30″ for beginning of Cool Planet portion of the video. Numbers below as stated in video – consider them an approximation depending on definition of “land availability” and quality. Nevertheless you get the idea:
~1%: run all cars
~2%:zero net carbon
~3%: 100 ppm reduction in 40 years
