Harrison Schmitt quotes:

It's like trying to describe what you feel when you're standing on the rim of the Grand Canyon or remembering your first love or the birth of your child. You have to be there to really know what it's like.

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.

[T]he great champion of the opponents of liberty, namely communism, had to find some other place to go and they basically went into the environmental movement.

But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.

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.

The 'global warming scare' is being used as a political tool to increase government control over American lives, incomes and decision making. It has no place in the Society's activities.

Time is, in fact, a cross to bear, it passes on inexorably and remorselessly, destroying everything in its wake, save art and works of the intellect.

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.

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

Nothing in the Constitution of the United States gives the Congress or the Executive Branch the power to attempt the task of regulating climate, as impossible as that would be under any realistic scenarios. No national security emergency exists relative to climate that would warrant increased governmental control of energy production. Today's Americans have an obligation to future Americans to elect leaders who do not believe in an omnipotent government but believe, as did the Founders, in limited government, and in the preservation of liberty and the natural rights of the people.
