I don't think the human effect [of climate change] is significant compared to the natural effect.

In Antarctica, it looks like the total volume (of ice) is increasing and if that's true, that's probably why you're getting increased ice moving away from the center of the continent and therefore these big icebergs and stuff are breaking off.

As a geologist, I love Earth observations, but it is ridiculous to tie this objective to a 'consensus' that humans are causing global warming when human experience, geologic data and history, and current cooling can argue otherwise. 'Consensus,' as many have said, merely represents the absence of definitive science. You know as well as I, the 'global warming scare' is being used as a political tool to increase government control over American lives, incomes and decision making.

It might be helpful to realize, that very probably the parents of the first native born Martians are alive today.

Several indisputable facts appear evident in geological and climate science that make me a true 'denier' of human-caused global warming.
