The Weekend Wonk: Richard Alley on Climate History and CO2
Peter Sinclair | Weekend Wonk | August 1, 2015At 3:50 a graph caught my eye because it dawned on me that in a way I was basically looking at "Mann's Hockey Stick" 15 years later. That is, after 15 years of accumulating data from all sorts of teams studying all sorts of proxies. This graph includes additional important information, such as solar irradiance, volcanic forcing, other 'forcings' among other information.
National Academy of Science member Richard Alley presents on 4.6 Billion Years of Earth’s Climate History: The Role of CO2, during the Symposium—Earths, Moons, Mars & Stars at the National Academy of Sciences 152nd Annual Meeting.
Matt Ridley: Cheerleaders for alarm. This is precisely what has happened with the climate debate and it is at risk of damaging the whole reputation of science.
Matt Ridley: The “bad idea” in this case is not that climate changes, nor that human beings influence climate change; but that the impending change is sufficiently dangerous to require urgent policy responses.
