Glacier

Thank you Adam yet again for such a wonderful, insightful documentary!

When this was filmed, Alaska was going through record temperatures. But the last three winters have been some of the coldest in decades.

This is one of the best videos on here, Adam. You have a lot to be proud of, as I have said before. I show this video to my middle school students every year during a persuasive writing unit in which they write a problem-solution essay. The video always holds their interest and inspires great discussion about our environment.

Thanks again.

Everybody should see this , it will make them realize that we need to take action now!!!

The Glaciers are astounding! I think it is unbelievably sad that something of that magnitude and beauty is just melting away. It is very frightening how much and how quick the earths temperature is rising. People should really open their eyes to these facts. I agree with Brooks in the movie The Shawshank Redemption when he said, "This World has got itself in a big damn hurry".

Ive got a bike you can ride it if you like.....

Adam, your videos are among the best I've seen. You educate and entertain, and this video is a perfect example of that.

I am worried, just as the entire world should be worried. God trusted us to care for our world and we have failed. It's not too late for us to fix it, though. I have been pleased with the growth of interest in "going green" among Americans lately.

Thanks again and keep up the great work.

For anyone who doubts that the planet is in fact warming up.
Alaska -- along with the other northern and southern extremes -- gets hit harder, and earlier, than temperate zones, so this should serve as a warning of what's to come. I guess, if you look at the one bright side to the glacial melt, tourism was on the rise in Alaska.

Until recently, global warming as a by-product of human consumption was a controversial theory that the White House resisted. That debate calls to mind an earlier scientific controversy from the Reagan era--over Nuclear Winter. The Nuclear Winter debate centered over what would happen if the U.S. and then Soviet Union ever went to war and fired a sufficient amount of their arsenals of nuclear weapons at each other, resulting in the detonation of, say, over 14,000 megatons--roughly 10 million times the explosive force that destroyed Hiroshima. Would this cause a nuclear winter and extinguish all life on earth, or would it merely make for a really, really bad day for hundreds of millions of human beings? Fortunately for us sentient beings, we never got the chance to find out which side was correct in the Nuclear Winter debate. Perhaps unfortunately--we'll see--this is not the case with the global warming. One way or another, we're going to find out.
