Gun Toting Liberal asked a question, to wit, when will I accept that global warming is caused by human activity and join him (or her as the case may be) in advocating the dismantling of modern energy and industrial production called for by Kyoto. A fair question.

When sites like this are shown to be irrelevent.

When people like Benny Peiser and Richard Lindzen do the same.

When someone demonstrates that burning carbohydrates is less harmful than burning hydrocarbons, because I am not giving up natural gas if burning wood turns out to be worse.

I am 45 years old, and can remember dire scientific predictions of global cooling. Check out this prediction from 1975:

“A major climatic change would force economic and social adjustments on a worldwide scale,” warns a recent report by the National Academy of Sciences.

[...]

(T)he Earth’s average temperature during the great Ice Ages was only about seven degrees lower than during its warmest eras – and that the present decline has taken the planet about a sixth of the way toward the Ice Age average. Others regard the cooling as a reversion to the “little ice age” conditions that brought bitter winters to much of Europe and northern America between 1600 and 1900.

Within less than a generation, so-called "settled science" has reversed 180 degrees from predicting a new ice age to melting ice caps. And scientists in the 70s were no less sure of themselves than today's group, either: "The evidence in support of these predictions has now begun to accumulate so massively that meteorologists are hard-pressed to keep up with it."

Predictably, these whoa-is-me climatologists had some whacky solutions for which they bemoaned a lack of political support:

Climatologists are pessimistic that political leaders will take any positive action to compensate for the climatic change, or even to allay its effects. They concede that some of the more spectacular solutions proposed, such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers, might create problems far greater than those they solve. But the scientists see few signs that government leaders anywhere are even prepared to take the simple measures of stockpiling food or of introducing the variables of climatic uncertainty into economic projections of future food supplies. The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality.

Oh, yeah, and all the computers are going seize up within minutes of Y2K.
