Want to see something different .... watch this:

 

sorry guys.. the problem you are to experience is because we have let mostly all of our sea ice and glaciers melt in Alaska and Canada... 25 years ago I could do a short walk to the face of glaciers less than an hour from my house... now its a 2-5 mile hike for those same glaciers if you really want to touch their faces now... last summer temps that are normally in the 60's F were in the 90's F.. so there is at least a silver lining to global warming.. just not in the tropics..

 

You are missing the point. If you look back 6 million years (they do this through deep ice core samples), the natural condition of the planet is to be cold. There are long periods of ice ages interrupted by brief spikes of warming. The current warming period we are in has been one of the longest lasting, and that is likely do to human factors. But the "cosmic" factors that lead to the big cycles are hugely more powerful. Many scientists now say that before the end of this century (ie, within the next 80 years) we are due according to these big cycles to enter the next ice age. These transitions are abrupt, it won't occur over hundreds of years, we will see winters getting colder and longer for several years, then all of a sudden it will be winter all year long. This is the alarm that is being sounded. A run away greenhouse hot planet is not what's in our future ... we should be preparing for a future where most of the agricultural area of the planet being under miles of ice.
