Almost half of the world's farmland has at least 10 percent tree cover, according to a study on Monday indicating that farmers are far less destructive to carbon-storing forests than previously believed. "The area revealed in this study is twice the size of the Amazon, and shows that farmers are protecting and planting trees spontaneously," Dennis Garrity, Director General of the World Agroforestry Center in Nairobi, said in a statement.

Global Warming is opening up new areas for fishing. We don't know that much about the ecosystems in these areas since they have been under ice until recently. Yesterday, U.S. Secretary of Commerce Gary Locke approved a plan to prohibit the expansion of commercial fishing in federal Arctic waters until researchers gather sufficient information on fish and the Arctic marine environment to try to prevent adverse impacts of commercial harvesting activity on the ecosystem.

Mexico is suffering from its driest year in 68 years, killing crops and cattle in the countryside and forcing the government to slow the flow of water to the crowded capital. There is insufficient data to say how much global warming can be blamed, a senior official said.

The U.S. Geological Survey released a study that showed mercury contamination in every fish sampled in 291 streams across the country. The work was part of the National Water-Quality Assessment Program (NAWQA) which provides an understanding of water-quality conditions such as whether conditions are getting better or worse over time and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis.

They say there's no place like home. But scientists are reporting some unsettling news about homes in the residential areas of California.

New research appearing in the online issue of the Proceedings of the U.S. National Academy of Sciences, Lawrence Livermore National Laboratory scientists and a group of international researchers found that model quality does not affect the ability to identify human effects on atmospheric water vapor.

The Earth's oceans were the warmest ever this July, according to a study released by the National Oceanic and Atmospheric Administration yesterday. The planet's ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA's National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.
