Here's a great article on some outlandish but intriguing geo-engineering ideas that are starting to get more attention.
The ideas are shrouded in controversy -- "Why are we speculating about whether we can construct concrete trees that may or may not effectively capture carbon from the atmosphere when we've got people's homes which aren't properly insulated? That's absurd," -- but still quite fascinating and fun food for thought leading into the Global Summit in Denmark next month:
If there were some kind of panic button to stop global warming, what would it look like? How about billions of tiny mirrors, launched into orbit to deflect solar rays away from Earth? Or big, fluffy clouds, artificially whitened so they reflect more sunlight back into space? Or maybe mechanical trees, ugly but effective at sucking carbon dioxide from the air along busy highways.

A bit overdue, but I want to take the opportunity to thank everyone who has contributed to our show, our website and shared their thoughts, comments, and encouragement. They are not always favorable (yes we know- Kevin's house is too big!), but most of them are very encouraging and are a big part of what has kept us going here. Seeing a new post or even some new sign-ups in the Share section of our site is the highlight of my day, and hearing that someone has watched our show, wants to learn more about sustainability, and is thinking about changing their businesses or homes as a result is music to our ears and confirms the potential that media can have in changing the way we live our lives and build our communities-- which is why we all got into this in the first place.
