    Often overlooked in the global warming debate is how little actual scientific evidence exists about the specific effects of increased levels of carbon in various regions of the world. Eco-Imperialism author Paul Driessen tackles this issue in his latest column:

    Climate models do help scientists evaluate possible consequences of changing economic growth, emission, cloud cover and other variables. But they can’t reproduce the actual climate of the past century. They cannot make accurate predictions, even one year in the future, much less fifty. They do not represent reality, and should not be relied on to guide public policy.

    Models reflect the assumptions and hypotheses that go into them – and our still limited understanding of complex, turbulent climate processes that involve the sun, oceans, land masses and atmosphere. … When the US National Assessment compared the results of two top-tier computer models for various regions of the United States, the models frequently generated precisely opposite rainfall scenarios … Depending on which model was used, the Dakotas and Rio Grande valley would supposedly become complete deserts or huge swamps; the Southeastern US would become a jungle or semi-arid grassland.

    Climate change is also about power. Power to control – and curtail – the power we rely on: to build, heat and cool our homes … produce raw materials, food and consumer products … transport people and products … and support modern living standards. … It’s about who gets to decide: how much energy we will have … where that energy will come from … what it will cost … and whether there will be enough energy to lift more families out of poverty.
