An expanded version of my recent Times column on ice ages:
Record cold in America has brought temperatures as low as minus 44C in North Dakota, frozen sharks in Massachusetts and iguanas falling from trees in Florida. Al Gore blames global warming, citing one scientist to the effect that this is “exactly what we should expect from the climate crisis”. Others beg to differ: Kevin Trenberth, of America’s National Centre for Atmospheric Research, insists that “winter storms are a manifestation of winter, not climate change”.
Forty-five years ago a run of cold winters caused a “global cooling” scare. “A global deterioration of the climate, by order of magnitude larger than any hitherto experienced by civilised mankind, is a very real possibility and indeed may be due very soon,” read a letter to President Nixon in 1972 from two scientists reporting the views of 42 “top” colleagues. “The cooling has natural causes and falls within the rank of the processes which caused the last ice age.” The administration replied that it was “seized of the matter”.
My Times column on AI and jobs:
In the early 1960s, at the Massachusetts Institute of Technology, there was a disagreement about what computers would achieve. One faction, led by John McCarthy and Marvin Minsky, championed “artificial intelligence”, believing that computers would gradually replace human beings. The other, led by Norbert Wiener and JCR Licklider, the man who oversaw the creation of the internet’s precursor, championed “human-computer symbiosis”, believing that computers would augment human beings.
