Professor Bob Carter of the Marine Geophysical Laboratory at James Cook University, in Australia gives what, for many Canadians, is a surprising assessment: "Gore's circumstantial arguments are so weak that they are pathetic. It is simply incredible that they, and his film, are commanding public attention."
Quote:
No; Carter is one of hundreds of highly qualified non-governmental, non-industry, non-lobby group climate experts who contest the hypothesis that human emissions of carbon dioxide (CO2) are causing significant global climate change. "Climate experts" is the operative term here. Why? Because what Gore's "majority of scientists" think is immaterial when only a very small fraction of them actually work in the climate field.

Appearing before the Commons Committee on Environment and Sustainable Development last year, Carleton University paleoclimatologist Professor Tim Patterson testified, "There is no meaningful correlation between CO2 levels and Earth's temperature over this [geologic] time frame. In fact, when CO2 levels were over ten times higher than they are now, about 450 million years ago, the planet was in the depths of the absolute coldest period in the last half billion years." Patterson asked the committee, "On the basis of this evidence, how could anyone still believe that the recent relatively small increase in CO2 levels would be the major cause of the past century's modest warming?"
Patterson concluded his testimony by explaining what his research and "hundreds of other studies" reveal: on all time scales, there is very good correlation between Earth's temperature and natural celestial phenomena such changes in the brightness of the Sun.

"The breaking glacier wall is a normally occurring phenomenon which is due to the normal advance of a glacier," says Winterhalter. "In Antarctica the temperature is low enough to prohibit melting of the ice front, so if the ice is grounded, it has to break off in beautiful ice cascades. If the water is deep enough icebergs will form."
Quote:
But Karl?n clarifies that the 'mass balance' of Antarctica is positive - more snow is accumulating than melting off. As a result, Ball explains, there is an increase in the 'calving' of icebergs as the ice dome of Antarctica is growing and flowing to the oceans.
Quote:
"Starting in 1970, there was a precipitous drop-off in the amount and extent and thickness of the Arctic ice cap." This is misleading, according to Ball: "The survey that Gore cites was a single transect across one part of the Arctic basin in the month of October during the 1960s when we were in the middle of the cooling period. The 1990 runs were done in the warmer month of September, using a wholly different technology."
Quote:
Karl?n explains that a paper published in 2003 by University of Alaska professor Igor Polyakov shows that, the region of the Arctic where rising temperature is supposedly endangering polar bears showed fluctuations since 1940 but no overall temperature rise. "For several published records it is a decrease for the last 50 years," says Karl?n
Quote:
The Canadian Ice Service records show that from 1971-1981 there was average, to above average, ice thickness. From 1981-1982 there was a sharp decrease of 15% but there was a quick recovery to average, to slightly above average, values from 1983-1995. A sharp drop of 30% occurred again 1996-1998 and since then there has been a steady increase to reach near normal conditions since 2001."
Quote:
Carter does not pull his punches about Gore's activism, "The man is an embarrassment to US science and its many fine practitioners, a lot of whom know (but feel unable to state publicly) that his propaganda crusade is mostly based on junk science."

Guess that global warming stuff was right
