Just a few quick points (since I think I’ll make it a NY resolution not to respond in as much detail to David's GW misinformation):
- It’s the Polar Science Center not the Popular Science Center.
- The plot David gave at his link is about an Arctic Oscillation of seal level pressure not sea ice volume or extent.
(Addition: I could not resist.
Below is the best estimate of Arctic Sea Ice extent from 1870 until ~2004 (Reference: ):
No evidence of what Spencer concocted in his mind of a rise in Arctic Sea Ice from 1930- 1970 coinciding with the increase in Sea Level Pressure (SLP). Thus his theory of Sea Ice Extent correlation with the SLP (with perhaps a few years of lag) is merely made up to suggest only natural forces have played a role in the large Arctic Sea Ice losses. See blue line going up from 1935-1970 bereft of any supporting data as to sea ice extent in that period.
I’d call that scientific fraud.
End Addition)
- David was wise not to charity wager on the sea ice volume in 2014 being greater than that of 1984.
- David really has to do more than call GW Effects all “speculative” when the professors and experts say otherwise. And the right wing publications David quotes are not experts. In the area of GW effects on biological systems, I’m no expert either. But I do know data analysis, infrared radiation in the atmosphere and thermal effects - 42 years experience in optical systems and infrared signatures/data analysis + good education (BS bioengineering, MS optical systems and MS in Environmental Management) . Thus I’m able to speak to IPCC WGI (The Physical Basis) info with a good degree of independent knowledge and cross checking (that is most of what we have debated thru the years), but not much on WG II (Impacts, Adaptation, and Vulnerability) info, and am getting better at WG III (Mitigating Climate Change) info with climate change/economics self-study and reading of Michael King/William Ruddiman/Barrie Pittick (Climate Change) and William Nordhaus/Nicholas Stern (Economics) among others.
