Great piece on the reality of wind as a source for energy.
Fantastic piece on wind energy and the reality of what it can do. To generate 1/2 of the worlds
power needs (half because wind cannot be depended on to flow at all times) we'd need 4 million 5 megawatt windmills that would cover 1% of the land that we have. Seems like a lot but 1% of usable land, and 4 million windmills (there are generally 50 million cars built per year) doesn't seem like much for clean renewable sustainable energy does is? Check it out here.

Chicago Prepares For Climate Change
Wild article in the New York Times about how Chicago is preparing for the coming storm. In 50 years the weather there is expected to be more like New Orleans than Chicago, so they are beginning to change sidewalks, roadways, and the types of trees they plant. It's hard to know if this is smart or not, but it seems like embracing what is happening (and trying to slow it at the same time) is the thing that makes the most sense. Check it out here.

How Meat Impacts The Environment
A great little graph (and more here) from Scientific American about the problems with eating meat. OF course they are talking about industrialized meat production but it's pretty alarming. Click on the pic to enlarge it.

Can white roofs save the world?
According to the site permanently changing the worlds rooftops would have the same effect as cutting out a full year of man made CO2 (in decreased cooling and heating costs). Cool.
Check it out.

Helping make the global warming argument
Time and again I find myself getting asked about Global Warming or, as it should more accurately be called, Global Climate Change. It's a tough one because it's so political and so large, but when you look at the science (oh dear, did I say science) it's actually quite simple. I generally try to convince people why they need to change using logic as it seems to cut through all of the left/right stuff that this topic brings up.
Having said all of that though, check out Skeptical Science, a very cool site that has a list of the generally raised "beliefs" about climate change and the science that refutes these claims. They even have a free iphone app that has the same info, so you can argue on the go! How cool (pun intended).

How To Talk To Global Warming Skeptics
A great article from Grist about how to answer global warming skeptics. Personally, I don't think it makes a stick of difference if it can be proven (at least whether or not we are causing it) because it's a question of acceptable risk, but some people need proof. Here's a good way to engage them.
Check it out.

The Only Climate Change Video You'll Ever Need To See
There's a fair amount of argument about climate change as I'm sure you know. The thing that always amazes me is that everyone is arguing about the wrong things. It's not about whether we are causing it or not (something which neither side can prve with 100% certainty), but whether or not we are willing to take the risks associated with being wrong. This video represents that argument perfectly and the answer is quite clear.

Return to the Gyre
For anyone interested in an update on the North Pacific Gyre, the plastic floating mass of garbage in the middle of the pacific, my friend Lyndsay just returned from a month at sea and had an article in the New York Times today. She told me that Captain Moore, who was back out with her, said that it has grown quite a bit since he was last there.

Blind Spot
Check out this preview from the web site that sells this film about the perils of peak oil. It's a bit of a depressing film but an important one nonetheless, and, most importantly, very accessible.

Go see The Age Of Stupid
A very cool looking movie that will hopefully make folks think a bit. A man in 2055 looks back at the year 2008 through video clips and asks the question : Why didn't they do anything when they had the chance?
Monday Sept 21, the makers of the film are holding a worldwide premiere in order to get it in the Guinness Book Of World Records and get some attention. To be a part of it check out the site.

The Cove
It's one thing to find a great documentary. It's another to find one that enlightens and inspires. And it's still another to find one that is so well made, that you'd swear it was scripted.
The Cove is just that and more. Check out the trailer below and then go see it with all your friends. Then call everyone else and tell them to see it.
Why you ask?
Because this illustrates how powerful one man can be, and moreso, has actually had an effect. To date, the annual dolphin slaughter that takes place in Taiji, Japan, has not begun. Will it eventually? Not if enough people see this film it won't.
If you've ever said "i'm just one person, what can I do", run out and see this film!
Oh yeah, and one final note. If you don't want to see the film because you think it'll be too graphic, fear not. I won't lie to you, there's a tough 2 minutes of film towards the end of the movie, but it's not nearly as bad as what you probably think you'll see, and what these filmakers probably saw. Check it out, you'll be glad you did.

The Daily Ocean
Finaly getting around to posting this. A reader sent in a link to her cool blog called The Daily Ocean. For 365 days she is picking up all trash she finds on the beach and cataloging it. Talk about an eye opener! Very cool.

Dirt
Another great doc, this one on the importance of topsoil and the problems we are facing in losing it.
