From a global warming advocate: Global warming: time to rein back on doom and gloom?
Prediction, as they say, is tough, especially when it’s about the future – and that’s especially true when it comes to the climate, whose complexity we only partially understand. It is, as we all know, naturally immensely variable. And the effect of human intervention is subject to long timelags: it will be decades, even centuries, before the full consequences of today’s emissions of carbon dioxide become clear.
As a result, scientists and policymakers draw on the past to predict the future. Until now, they have therefore placed much weight on the rapid temperature increases in the Eighties and Nineties. But for at least a decade, these have dramatically slowed, even as carbon dioxide emissions have continued to increase. [emphasis mine]
Or as I like to say, every climate model proposed by every global warming scientist has been proven wrong. They all predicted the climate would warm in lockstep with the increase in CO2. It hasn’t.
This is not to say the climate hasn’t warmed in the past five centuries (though some of the data used in for the past 150 years is sadly suspect). What isn’t clear is why. It might be the rise in carbon dioxide. It might also simply be the lingering warming the Earth is experiencing as the last ice age ends. Or it might be because of the Sun.
The field of climate science is very complex, confusing, and in its infancy. We just don’t know yet, and anyone who says they do is not a good scientist.
