The world is warming, these facts are not disputed... The problem that we are going to run into is the "snowball effect". This is basically the idea that as the world warms it melts more snow... This snow used to reflect the heat from the sun, but now the much darker ground or water absorbs more of the suns heat... This increases global warming... More snow melt = faster warming... The same goes for melting permafrost. All of this permafrost that is melting contains methane gas which is a greenhouse gas just like carbon dioxide. As the world warms, it releases more and more trapped methane gas from the permafrost which only make global warming accelerate even more. More permafrost melt = More methane = faster warming. If we don't act quickly we will be past the point of no return, that is if we haven't passed it already...

Arctic Ice In A "Death Spiral"
Well we didn't manage to beat last years record thaw in the Arctic, but this years melt was the second worst on record in the Arctic. A disturbing trend has been forming over the past few decades and it looks like things are only going to get worse. Remember all of this melting is just going to increase the Snowball Effects of Global Warming. The more ice that is melted the more heat is absorbed by the darker seas. Also methane and other greenhouse gases are released as the ice continues to melt...
What do you think of this latest report? Have we finally passed the tipping point of no return?

The Glaciers Around The World Are Melting
As the glaciers around the world melt the water that is run off lubricates the glaciers and make them retreat even quicker. Also the more water puddles on the tops of the glaciers the more heat is trapped in that water. Think of it this way, you can have a white shirt (snow and ice) or a black shirt (water) in the summer, which would you choose? Glad I don't live on the coast...
