NASA finds 2011 ninth warmest year on record; GISS team concludes slowdown of warming likely to prove illusory

Green Car Congress

The global average surface temperature in 2011 was the ninth warmest since 1880, according to NASA scientists; nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000. The average temperature around the globe in 2011 was 0.92 degrees F (0.12 degrees F (0.12

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.

NOAA study: Increase in stratospheric aerosols has offset some recent climate warming

Green Car Congress

A recent increase in the abundance of particles high in the atmosphere has offset about a third of the current climate warming influence of CO 2 change during the past decade, according to a new study led by NOAA and published in the online edition of Science. The increase in aerosols since 2000 implies a cooling effect of about 0.1

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.
