Climate modelers and disaster proponents remind me of four guys who were marooned on an island, after their plane went down. The engineer began drawing plans for a boat; the lumberjack cut trees to build it; the pilot plotted a course to the nearest known civilization. But the economist just sat there. The exasperated workers asked him why he wasn’t helping.
“I don’t see the problem,” he replied. “Why can’t we just assume we have a boat, and simply leave?”
In the case of climate change, those making the assumptions demand that we act immediately to avert planetary crises based solely on their computer model predictions. It’s like demanding that governments enact laws to safeguard us from velociraptors, after Jurassic Park scientists found that dinosaur DNA could be extracted from fossilized mosquitoes, and brought the “terrible lizards” back to (Hollywood) life.
Climate models help improve our conceptual understandings of climate systems and the forces that drive climate change. However, they are terrible at predicting Earth’s temperature and other components of its climate. They should never be used to set or justify policies, laws or regulations – such as what the Environmental Protection Agency is about to impose on CO2 emissions from coal-fired power plants.
Even our best climate scientists still have only a limited grasp of Earth’s highly complex and chaotic climate systems, and the many interrelated solar, cosmic, oceanic, atmospheric, terrestrial and other forces that control climate and weather. Even the best models are only as good as that understanding.
Worse, the models and the science behind them have been horribly politicized. The Intergovernmental Panel on Climate Change was ostensibly organized in 1988 to examine possible human influences on Earth’s climate. In reality, Swedish meteorologist Bert Bolin and environmental activist groups wanted to use global warming to drive an anti-hydrocarbon, limited-growth agenda. That meant they somehow had to find a human influence on the climate – even if the best they could come up with was “The balance of evidence suggests a discernible human influence on global climate.” [emphasis added]
