Thanks for the video. I remember discussing this in in grade school and back then it was estimated it would melt in 50,000 years...now it's said to be 5,000. I'd say HUGE changes will be happening in less than 50 years. They're not accounting for the fact that as the ice melts more carbon and methane is released speeding up the process exponentially. Man made or not...it's happening.
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.
permafrost-covered northern latitudes of Russia, Europe, Greenland and North America. The estimated 1,672 billion metric tons of carbon locked up in the permafrost is more than double the 780 billion tons in the atmosphere today.
I'm seeing effects of just a small amount of rising sea levels where I live. Areas that never flooded near the ocean flood constantly now. There are some houses that people can no longer maintain insurance on the houses and some are just abandoned. Others are raised at a huge expense.

North America....New York and Long Island are under water.....(Edit: And so is Florida. Where I planned on retiring to. Ooops!)
It doesn't look like much of a difference, but it is.....Australia....
