In Scientific American Viscount Matt Matt Ridley argues climate change "is real, man-made and not dangerous, at least not for a long time." He notes recent research show Earth is not as sensitive to changes in carbon dioxide levels as most climate models assume because most of the sensitivity built into the models comes from faulty assumptions about feedback effects from water vapour, clouds, aerosols, etc, all of which are poorly understood. Ridley also notes the most recenrt IPCC reports debunked claims about "tipping points" showing a sudden methane release from the ocean or slowdown of the Gulf Stream are "very unlikely" and a collapse of the West Antarctic or Greenland ice sheerts during this century is "exceptionally unlikely". Since any climate harms from increased atmospheric carbon dioxide are far off, Ridley says restrictions on fossil use are likely to do more harm than good.
