Policies devoted to bioenergy should be redirected toward efforts to protect terrestrial carbon stocks and recarbonize the biosphere.
Flooding can convert soils from a methane sink to a methane source to the atmosphere
No matter how much carbon they assimilate, the carbon uptake by an existing mature forest is not additional,
production of wood pellets for fuel is likely to put more CO2 in the atmosphere and maintain less biodiversity on the land during the next several decades.
If we are to store carbon in soils, better management of agricultural lands might be one avenue to pursue.
Enhancement of natural carbon sinks would allow a more orderly withdrawal of fossil fuels from our economy during the next several decades.
if we added iron to a large area of the world’s oceans, we could dramatically lower the level of carbon dioxide in Earth’s atmosphere.
The CO2 storage capacity of areas favorable for CCS in the United States amounts to 150 x 1015 g of CO2—equivalent to about 25 years of our emissions at current levels.
When forests cover the landscape, they increase the absorption of incoming sunlight
When the arctic is melting rapidly, this is no time to get bogged down in conservative rhetoric.
