On December 15, four leading scientists appeared before the Canadian Senate Standing Committee on Energy, the Environment and Natural Resources to challenge global warming advocacy. The hearing was the first of its kind in Canada. (Video of the hearing can be found here.)
Guelph University Professor of Economics Dr. Ross McKitrick led off the hearing, explaining that the foundation of the climate scare — the science as promulgated by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) — cannot be trusted:
The so-called Climategate emails confirmed the reality of bias and cronyism in the IPCC process. … IPCC Assessments are guaranteed merely to repeat and reinforce a set of foregone conclusions that make up the party line.
McKitrick explained how his research showed that much of the warming seen in the IPCC surface temperature record is almost certainly a result of urbanization, agriculture, and other land use changes, not greenhouse gases (GHG). He also found that the 50-year record of temperatures measured by balloons does not show the warming trend forecast by climate models.
University of Ottawa (U of O) Professor of Earth Sciences Dr. Ian Clark addressed the committee:
We have not really seen any global warming for the past 10 years. … This is in stark contrast with the IPCC forecast of an increase of some 0.2 degrees per decade.
Clark explained that 20th century warming is merely one of a series of warm periods in the last 10,000 years. During these intervals, carbon dioxide — the greenhouse gas most targeted by governments around the world — was relatively steady:
CO2 had nothing to do with these warming periods.
Clark continued, showing that the last 500 million years show no correlation between temperature and CO2. He explained that water vapor is in fact responsible for the majority of the greenhouse effect. Clark also promoted the theory that the Sun, not CO2, is driving climate change. He concluded:
It is time to turn our attention to real, tangible environmental problems.
Many people think the science of climate change is settled. It is not. … [The Sun] drives the water cycle; the water cycle then generates climate, and climate decides how much jungle, how much tundra and so on we will have, and therefore drives around the carbon cycle. … The sun also warms the oceans that emit CO2 into the atmosphere. Atmospheric CO2 is thus the product and not the cause of the climate.
