Parts of the State of Rio Grande do Sul, in Brazil, were buried under a freek snowstorm that left them with over EIGHT FEET of snow. They get frost down there sometimes, but they are NOT used to that much snow......
Jist a chill'n thought for you folks that must work out in the weather today....or don't live next to Lake Refrigerator....
"A one-degree global change is significant because it takes a vast amount of heat to warm all the oceans, atmosphere, and land by that much. In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. A five-degree drop was enough to bury a large part of North America under a towering mass of ice 20,000 years ago."

"According to the guys who brought us outerspace and the moon walk, NASA's Goddard Institute for Space Studies says the earth is not cooling, it is getting warmer. It's not a pressure cooker. The world is not boiling over. In fact, temperatures have risen about two degrees on average since 1880. So if the average earth temperature back then was 70 degrees, it is now 72 degrees.
Most of the warming occurred after 1975, when we started burning fossil fuels in greater numbers, especially in emerging markets and the US.
Why should we care about two degrees of warming?
The global temperature record represents an average over the entire surface of the planet. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable cyclical events (night and day, summer and winter) and hard-to-predict wind and precipitation patterns. But the global temperature mainly depends on how much energy the planet receives from the sun and how much it radiates back into space -- quantities that change very little. The amount of energy radiated by the Earth depends significantly on the chemical composition of the atmosphere, particularly the amount of heat-trapping greenhouse gases, NASA scientists say..."
