Now that Sarah Palin has announced her resignation as Governor of Alaska, you may wonder: What has she been doing? How will she fill her time? In an Op-Ed piece for The Washington Post, Palin kindly provided an answer. She's committed herself to a single task: confusing the American...

Driving many conversations on energy and climate is a single question: What will the future look like?

Even if you're not interested in the environment, you've asked a similar question before. If you've ever wondered what the weather will be over your vacation, if you've ever filled out a sports...

Consider the argument that climate change solutions,...

I went to bed last night with Oxford covered in a thin, quiet blanket of snow. I woke up to find the country in chaos.

The Telegraph ran a headline saying, "Britain paralyzed by worst snowfall for 20 years." Meanwhile, the usually reserved Times of London reported: "Chaos...

Imagine, if you will, a story. In this story most of the characters are mute. The threats are abstract, the timeline long, the stakes high and the consequences still uncertain. Politics are present, and so, too, are heaps of money. There are enemies, but no battlefield. There is no climax....

On November 4th, Americans will cast their vote for our next President. In doing so, they will cast a vote for a candidate not on the ballot -- America's next environment.

If you're anything like me, you've landed in Denver. The weather is perfect, and the mountains unlike anything back home.

On the Sunday before the official start of the Democratic scrum, you're most likely planning the week. Where do I eat? How I rent one of those bikes? How can...

Last time the Democrats came to Denver, the powerbrokers drove electric-gasoline hybrid cars. Thousands of trees were given away. Snow was trucked in by horse and carriage to cool the convention center. And the candidate - the candidate stayed home to harvest his alfalfa crop.
