Shellfish reefs are 'most imperilled sea habitat'
May 22, 2009 07:34 AM - Peter Aldhous, New Scientist
Globally, 85 per cent of reefs have been lost. Destructive fishing practices, disease and coastal development threaten many of the survivors.

New auto standards: the start of Obama’s green revolution
May 21, 2009 07:00 AM - Mark Trumbull, The Christian Science Monitor
President Obama’s announcement on tailpipe emissions Tuesday reaffirmed a commitment that goes beyond regulation of the auto industry. The move is part of a broader White House strategy to confront the risk of global warming while making green-collar jobs a centerpiece of the economy. For ordinary Americans, the resulting changes could be far-reaching. Lighter-weight vehicles appear likely to become more popular. More tax dollars are being tabbed for clean-energy technology. And for years to come, college students might find that some of the hottest job opportunities lie in helping to keep the planet cool.

In a landmark decision on climate change and energy, President Barack Obama will announce tough new vehicle gas-mileage standards on Tuesday, the first ever national limits on greenhouse-gas emissions. The new policy, which was worked out between Washington, state governments and the auto industry, will require automakers to meet a minimum fuel-efficiency standard of 35.5 miles a gallon by model year 2016 — four years earlier than Congress currently requires.
