From Matt Ridley's "Angus Millar Lecture of the Royal Society of the Arts" in Edinburgh, titled "Scientific Heresy":
"Stalagmites, tree lines and ice cores all confirm that it was significantly warmer 7000 years ago. Evidence from Greenland suggests that the Arctic ocean was probably ice free for part of the late summer at that time. Sea level is rising at the unthreatening rate about a foot per century and decelerating.
Greenland is losing ice at the rate of about 150 gigatonnes a year, which is 0.6% per century. There has been no significant warming in Antarctica, with the exception of the peninsula. Methane has largely stopped increasing. Tropical storm intensity and frequency have gone down, not up, in the last 20 years. Your probability of dying as a result of a drought, a flood or a storm is 98% lower globally than it was in the 1920s. Malaria has retreated not expanded as the world has warmed.
And so on. I’ve looked and looked but I cannot find one piece of data – as opposed to a model – that shows either unprecedented change or change is that is anywhere close to causing real harm."
