Deserts crossing Mediterranean
June 27, 2009 07:08 AM - ANSA.It, Environmental Health News

The Sahara Desert is crossing the Mediterranean, according to Italian environmental protection group Legambiente which warns that the livelihoods of 6.5 million people living along its shores could be at risk. "Desertification isn't limited to Africa," said Legambiente Vice President Sebastiano Venneri. "Without a serious change of direction in economic and environmental policies, the risk will become concrete and irreversible."

NASA readies 'sandbox' to plot Mars rover's escape
June 23, 2009 03:15 PM - Rachel Courtland, New Scientist

NASA plans to fill a 'sandbox' with simulated Martian soil this week to test escape maneuvers for the Mars rover Spirit, which has been stuck in a sand trap called "Troy" since early May. When the rover first became stuck, its wheels slipped so much in the fine, flour-like soil that Spirit moved just centimeters despite the fact that its wheels had rotated enough to move it about 10 metres away. Mission managers then stopped trying to drive the rover, whose wheels had already become buried halfway into the loose soil.

Massive supercomputers that devour electricity to keep them humming are not exactly the poster children for green technology. But IBM hopes to change that with its plans to build a supercomputer that will use water to keep the system cool and even recycle some of the waste heat to help heat the university where it’s housed.

US EPA Issues Clean Energy Action Guide for States
June 22, 2009 01:38 PM - Editor, ENN

The potential energy savings achievable through state actions is significant. EPA estimates that if each state were to implement cost-effective clean energy-environment policies, the expected growth in demand for electricity could be cut in half by 2025, and more demand could be met through cleaner energy supply. This would mean annual savings of more than 900 bil­lion kilowatt-hours (kWh) and $70 billion in energy costs by 2025, while preventing the need for more than 300 power plants and reducing greenhouse gas emissions by an amount equivalent to emissions from 80 million of today’s vehicles.
