Rather than calling what's happening on our planet right now 'Global Warming' a more accurate term would be 'Global Weather Oscillations'. Our atmosphere and weather systems are basically a heat engine powered by the sun. The sun heats different parts of the planet differently depending on if it's land or ocean. Heat rises, hits the upper atmosphere, cools and falls in the form of precipitation and associated wind. Because we're on a spinning planet with nights and days things get more interesting and more complex than what you can duplicate at home with just a terrarium and a heat lamp.

As we trap more heat in our bigger spinning terrarium things get more severe as we begin to lose the ability to dissipate the accumulated heat the way that has been happening before.

The net effect is that what we have considered to be normal and seasonal weather oscillations are becoming more severe and more unpredictable. That wreaks havoc in the traditional ways people have been living for as long as we can remember.

I don't want to get all 'Water World' with you folks, but I think sailors are uniquely qualified, by their own nature, to survive much of what's happening climatically than the average yokel in a beach shack. (Not that there's anything wrong with that! ;) )
