I wonder how long it will be before enviromentalists start freaking out about Global Cooling. The so called global warming is just a phase in the Earth's life. Warming happens, then cooling happens, then warming happens, then an ice age happens where wooly mammoths that sound like Ray Ramano run around, then some more warming happens.....etc,etc. It is the way of the world.
Yes, that is the way the world normally works. But the rate at which the globe's temperature is rising is exponentially higher than it did in warm phases before humans started using coal, fossil fuels, etc.
