Hal, humans are most definitely causing global climate change. That being said, there are many drivers to this, one of which is increased C02 in the atmosphere. It is simplistic to yell Global Warming when you read these articles. That is what I have an issue with. In the late 70's there was an impending doom of a coming ice age. Here's a counter-argument that I will make. Fear breads consumption. Global Warming is one of the great fears of many, yet we all know that as individuals there is little we can do to curb an increase in C02 levels in the atmosphere. Perhaps the reason that Global Warming is such a prevalent fear, over something like sustainable living (aka zero footprint), is that adopting a zero footprint approach to living would cause mass producers significant financial harm. Just a thought. Remember how much profit was made over Y2K fears?
