If you think real hard, back to elementary school, when you learned about the "hydrologic or water cycle" on "planet earth". Water is in constant movement. It flows in rivers, into lakes and oceans, and is evaporated from the same to fall again as rain and snow. Cold air holds much less water vapor than does warm air. That is why the western sides of mountain ranges are usually very wet and the eastern side very dry, because as the air climbs up the mountains it cools and loses moisture in the form of rain and snow. So it is dried out as it flows over the other side. The same applies to land masses that are reasonably flat to a lesser degree.
Fast forward to today, in the era of "global warming" or "climate change". The planet is supposedly warming up. I don't think it is "human" caused, but is just a natural cycle, since for the last 2 1/2 million years we have been in an ice age cycle. We all know what kind of weather we are having here this winter, and Europe has been hammered with bitter cold and snow. Since the "scientists" tell us that during this past summer more of the Arctic ice cap has melted, with more open water, than ever before, I thought I would re post a portion of something I wrote back on November 30, 2009.
"We are in an interglacial period right now, since the last
continental glaciers finished receding about 10,000 years ago. Over the
last 2 1/2 million years, the earth has had 5 glacial periods during
which up to 30% of the continents were covered with glaciers up to a
mile thick. Where did all that ice come from? When I was at the
University of Connecticut, majoring in Geology back in the early 60's,
we discussed a theory of the ice ages that still makes a whole lot of
sense, and shows that what is going on today is natural and not caused
by humans.
About 2/1/2 million years ago, the continents
arrived (continental drift) at their present locations. This set the
stage for the start of the first ice age. At that time the Arctic ocean
was open water. This allowed tremendous evaporation from the ocean that
fell as snow across the continents. This eventually caused glaciers to
start forming on the continents. All that snow and ice on the land
caused a lot of sunlight to be reflected back into space causing the
global temperature to drop causing global cooling and further
glaciation. Eventually, the planet cooled to the point where the Arctic
ocean froze. This cut off the evaporation that lead to the creation of
the continental ice glaciers. With the influx of new snow cut off, the
glaciers slowly started receding. As they receded, more land was exposed
and not as much sunlight was reflected back into space, so the planet
started warming again. Eventually, the glaciers disappeared as the
planet warmed to the point that the Arctic ocean melted and became ice
free again. The cycle started all over again, as it has five times, and
will continue to do so until the continents realign themselves again. If
the earth is warming, and the Arctic ocean is melting as the doomsayers
would have you believe, then when it becomes ice-free again, I hope you
have a big snow shovel, because we'll be headed into another ice age."
