According to meteorologist Jeff Masters, record-breaking snowstorms are an indication that global warming is occurring. Due to the extra moisture which global warming has added to the atmosphere which is an extra 4% since 1970. But why doe an increase air temperature increases snowfalls?
The answer is simple science and more common sense than science. If the air has warmer temperature it creates more moisture in the air and moisture-laden air mixes with temperatures cold enough to snow resulting to an increased amount of snowfall. And warming of the ocean water temperatures also has an effect in snowfall.
NASA said, "El Niños occur when trade winds that normally blow east to west over the equator relax over the Pacific Ocean and surface waters in the eastern Pacific becomes warm. This warming or cooling of the eastern Pacific Ocean changes precipitation patterns around the world. Right now, our country the Philippines is having this El Niño phenomenon or drought which is causing rotating brownouts around the archipelago.
Global warming wouild mean that the average temperature across the entire planet across an emtire year would be higher. But that wouldn't mean everywhere would get equally hotter, or that some places wouldn't get colder than in the past, especially in winter. Climate is a very complcated system, and people have suggested that global warming can have effects like changing the path of the Gulf Stream in the Atlantic, or of jet streams high up in the atmosphere.
For example the Gulf Stream keeps Great Britain from not being as cold as Alaska, so if it flowed differently, that could make Britain a lot colder, at least in winter. -- Quote CLIMATE change researchers have detected the first signs of a slowdown in the Gulf Stream — the mighty ocean current that keeps Britain and Europe from freezing. They have found that one of the “engines†driving the Gulf Stream — the sinking of supercooled water in the Greenland Sea — has weakened to less than a quarter of its former strength.
The weakening, apparently caused by global warming, could herald big changes in the current over the next few years or decades. Paradoxically, it could lead to Britain and northwestern and Europe undergoing a sharp drop in temperatures. -- /Quote http://www.timesonline.co.uk/tol/news/uk/article520013.ece http://www.bbc.co.uk/climate/impact/gulf_stream.shtml http://www.bbc.co.uk/science/horizon/2003/bigchilltrans.shtml Regarding your point about humidity... global warming would lead to a faster rate of water evaporation from the sea, which is expected to result in more rainfall.
I suppose it could also result in more snowfall if the extra water vapour found its way to places cold enough for it to fall as snow.
Yes increase snowfall is definitely a sign that global warming is still in effect . The fact that snow is currently in every state in USA is consistent with global warming. Even Hawaii has some snow on its mountain top.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
