Extract DROP the level of GHG emissions in the atmosphere Stopping or reducing GHG emissions alone is unlikely to suffice if the world is to meet its climate goals; we also need to find ways to remove GHGs that remain in the atmosphere from past decades of industrial activity. In fact, we will need net-negative emissions by 2100 if we’re to keep global temperatures at or below 2oC, according to 9 out of 10 presentations analyzed by the Intergovernmental Panel on Climate Change (IPCC). GHGs are sticky; they remain in the atmosphere for centuries if left to natural processes alone, so if we ‘overshoot’ our GHG emissions budget, we must remove GHGs to meet climate goals. The good news is that agriculture offers enormous potential to serve as a carbon sink, in effect mopping up excess GHGs from the atmosphere, because of the carbon-storing capabilities of healthy soil. At COP21, a range of agricultural GHG sequestration proposals were on display, such as the 4 per 1000 soil carbon initiative, the Bonn Challenge landscape restoration effort, and the Great Green Wall afforestation project. The launch of the 4 per 1000 soil carbon initiative to a busy crowd in the French Pavilion at COP21. In addition, land managers have a number of other strategies to build up carbon in soils. This Project Drawdown video summarizes the wide range of “carbon farming” strategies. Advances in biotech to perennialize crops to require less GHG-intense cultivation also hold great potential to build up soil carbon levels. As do bio-pesticides and other biological fertilizers, such as biochar, which help farmers to increase their yields while improving the health of the soil and reducing soil carbon erosion. Lastly, innovations to turn marginal or degraded land back into productive, carbon sequestering-acreage will fetch higher and higher premiums as the demand for terrestrial carbon sequestration makes fertile land more valuable. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
