Millions of years ago, rivers ran in Antarctica through craggy mountain valleys that were strangely similar to the modern European Alps, Chinese and British scientists reported on Wednesday. In a study published by the British journal Nature, the scientists described a vast terrain that had been hidden beneath ice up to two miles thick for eons, until new imaging technology recently uncovered them.

Brazil approved on Wednesday an environmental permit for a hydroelectric dam in the Amazon, an official said on Wednesday, advancing a project the government hopes will shore up power supplies but critics call an ecological disaster.

Agriculture Holds Key to Solving Global Warming

Agriculture, so often cited as a factor in global decline - for claiming natural grasslands that store carbon, soil erosion and pesticide runoff - could become a big part of the solution to global warming, according to a hopeful report by Worldwatch Institute released today.

Energy Leaders Launch Efficiency Partnership

Energy ministers from the world's largest economies have formally launched the first high-level body focused exclusively on advancing energy efficiency worldwide. While several international forums exchange energy advice, the International Partnership for Energy Efficiency Cooperation seeks to elevate that information to a level that affects policymaking.

Analysis Finds Elevated Risk From Soot Particles in the Air

A new appraisal of existing studies documenting the links between tiny soot particles and premature death from cardiovascular ailments shows that mortality rates among people exposed to the particles are twice as high as previously thought.

Researchers were stunned to discover recently that Earth is losing more of its atmosphere than Venus and Mars, which have negligible magnetic fields.

Global Bird Species in Serious Decline
June 2, 2009 06:44 AM - Ben Block, Worldwatch Institute

Researchers have known about the speckled brown Sidamo lark for only 40 years. Always a rare sight, the elusive bird may soon vanish from the prairie grasses of Ethiopia forever. Its habitat already restricted to less than 100 square kilometers, the lark is rapidly losing territory as local residents, the Borana ethnic group, convert grassland into heavily grazed pasture. Unless the Borana are allowed to resume their nomadic ways, within the next few years the Sidamo lark will likely become the first known bird species to vanish from mainland Africa, researchers say.

NASA Satellite Detects Red Glow to Map Global Ocean Plant Health

A study published by NASA uses satellite remote sensing technology to measure the amount of fluorescent red light emitted by ocean phytoplankton and assess how efficiently the microscopic plants are turning sunlight and nutrients into food through photosynthesis. They can also study how changes in the global environment alter these processes, which are at the center of the ocean food web.

Climate change turning seas acid

Climate change is turning the oceans more acid in a trend that could endanger everything from clams to coral and be irreversible for thousands of years, national science academies said on Monday. Seventy academies from around the world urged governments meeting in Bonn for climate talks from June 1-12 to take more account of risks to the oceans in a new U.N. treaty
