I’ve long viewed the anthropogenic global warming (AGW) denial movement with a certain sense of bemusement. The causal links are rock-solid – could it really be a coincidence that atmospheric CO2 levels started rising at the very same moment as industrial civilization got into swing, within decades reaching magnitudes big enough to decisively interrupt the glacial-interglacial cycle that previously held steady for hundreds of thousands of years? Is it really surprising that given the heat-absorbing properties of CO2 (known to science since the 18th century), global temperatures entered into a period of steep ascent since the 1970s, rising by around 0.9C from the 1900-1910 period to the last decade? Occam’s Razor anyone? And considering that only 6C or so separate us from the Ice Ages, when ice sheets descended into central Europe, southern England was a polar wasteland scoured by icy, dust-laden winds and dessication affected even the tropics, should not even the possibility of seeing the world warm by up to 6.4C during this century – corresponding to the high end of the IPCC’s forecasts in 2007 – invoke a certain level of concern?
I plan to write more on climate change, since it is going to be one of the key trends of this century (along with resource depletion and growth in computing power). But for now – and to forestall any future objections – I would like to take a moment to expose the top myths and misconceptions of AGW deniers.
It’s all a conspiracy – scientists want research funding and environmentalists want to impose socialism on us.
Frankly the idea that tens of thousands are colluding in a massive conspiracy is risible. If anything it is the denier camp which has economic incentives to promote their views, given the funding they receive from the fossil-fuel industry. The Bush administration scientists pursued a campaign of disinformation and outright censorship regarding AGW. So who are the real conspirators?
