Alarmists refuse to take on skeptical geologists
Anyone not already familiar with the stance of geologists towards the global warming scare would have been shocked by the conference at the University of Ottawa at the end of May. In contrast to most environmental science meetings, climate skepticism was widespread among the thousand geoscientists from Canada, the United States and other countries who took part in GAC-MAC 2011 (the Joint Annual Meeting of the Geological Association of Canada, the Mineralogical Association of Canada, the Society of Economic Geologists and the Society for Geology Applied to Mineral Deposits).
The lead symposium of the conference, Earth climate: past, present, future, was especially revealing. Chaired by University of Toronto geology professor Andrew Miall, the session description starts: “The scientific debate about climate change is far from over. Some of the projections of climate change and its consequences contained in the 2007 Report of the Intergovernmental Panel on Climate Change (the United Nations’ IPCC) have been called into question. This symposium will address some of these issues and present a geological perspective on the scientific debate.”
The talks were from “climate rationalists,” defined by Australian geology professor Bob Carter of James Cook University as “persons who are critical (on balanced scientific grounds) of the IPCC’s alarmism … reflecting the primacy that such persons give to empirical data and thinking. The climate rationalist approach contrasts markedly with the untestable worlds of computer virtual reality that so many climate alarmists now inhabit.”
Leading off the GAC-MAC climate symposium was fellow Australian, Ian Plimer, professor in the School of Civil, Environmental and Mining Engineering at the University of Adelaide. In a keynote presentation entitled Human-induced climate change: Why I am skeptical, Plimer completely dismantled the greenhouse-gas-driven climate-change hypothesis. He showed how climate has varied naturally on all time scales and how recent changes are not unusual. Plimer explained the lack of meaningful correlation between the greenhouse gas carbon dioxide (CO2) and planetary warming and cooling, and how “climate models throw no new light on climate processes.” He concluded, “Pollution kills, CO2 is plant food, H2O vapour is the main greenhouse gas…. Humans can adapt to future changes.”
Following Plimer were 14 other climate presentations by leading geoscientists. Henrik Svensmark of the National Space Institute in Denmark spoke about how cosmic ray variations in the atmosphere are influencing climate by changing the microphysics of clouds. University of Ottawa emeritus professor Ján Veizer presented his research describing the role of the Sun and water vapour on CO2 and climate change. Calgary geophysicist Norm Kalmanovitch showed how satellite radiation measurements demonstrate that the “enhanced greenhouse effect” from greenhouse gas emissions has never even existed to any measurable extent. Carleton University researcher Hafida El Bilali showed how her work with paleoclimatologist professor Tim Patterson revealed that variations in the output of the Sun have had major influences on regional climate for the past nine millennia.
And so it continued. Although one speaker presented information that was consistent with IPCC claims, no other presentation in the symposium supported the UN’s human-caused dangerous global warming hypothesis. In the discussion period following the talks, climate rationalists decried the lack of media or public attention to the symposium or their research findings. In the exhibit hall, few participants seemed interested in human-caused global warming. The catastrophic messages that so overwhelm other climate-related conferences were nowhere to be found.
Where were all the other scientist supporters of climate alarmism? Did they not know that climate was a major focus of this, the largest geologic conference in the country?
They knew. According to Miall, even though some were directly invited, they either refused to participate or ignored the invitation. “The people on the IPCC side generally will not debate,” explained Miall. “Anything that’s brought up that they disagree with, they say has been dealt with and is no longer considered important, or is a minor effect. This is often quite wrong.”
