A Car that Runs On Air

The author of today’s article, Sheryl Canter, is an Online Writer and Editorial Manager at Environmental Defense.

In poking around the blogosphere recently, I found several references to a Popular Mechanics article about something called an "Air Car". Air Car?? What I read left me with some questions, so I found the inventor’s Web site and did some further reading.

It sounds like science fiction, but it’s true. A car that runs on air – compressed air – will be sold in India starting in August 2008. It’s designed mainly for city driving, and produces zero carbon emissions.*

That Senate Energy Bill

Today’s guest blogger, Tony Kreindler, is a Media Director at Environmental Defense.

There’s been a lot of buzz lately about the Energy Bill under debate in the Senate. With all the lobbying and spin, it can be hard to sort out what’s really going on. Here’s the bottom line.

When it comes to solving climate change, our best yardstick for measuring success is how much we cut global warming pollution. The Energy Bill could make some progress, but it’s no substitute for the comprehensive climate legislation Congress will work on later this year. Let’s look at the numbers.

Storm Hits Oman

Today’s post is by Bill Chameides, Chief Scientist at Environmental Defense.

The hurricane season began on June 1, and we are all waiting with some dread to see what this year will bring. Will it be a relatively mild season like last year, a devastating one like 2005, or something in between? An ominous sign is that we have already seen two tropical storms in the region: Andrea, which formed almost a month before the season began, and Barry, which formed on the first day of the season.

Last week I read that Oman was hit by Tropical Cyclone Gonu. ("Hurricane", "typhoon", and "cyclone" are all names for the same thing.) I know that Asia and Australia are regularly hit by tropical storms, but the Arabian Peninsula? Is that normal? I didn’t know, so I decided to do a little investigating. Here’s what I learned.
