Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. Tropical peatlands cover more than 25 Mha in Southeast Asia and are estimated to contain around 70 Gt of carbon.

Warming Climate Threatens California Fruit and Nut Production

Green Car Congress

Winter chill, a vital climatic trigger for many tree crops, is likely to decrease by more than 50% in California during this century as global climate warms, making the state no longer suitable for growing many fruit and nut crops, according to a team of researchers from the University of California, Davis, and the University of Washington.
