I was trying to look up some material on ice ages. I found this chart: http://www.geo.sunysb.edu/cei542/Workgroups/atmosphere/vaughn/figure1.htm
but the scale is hard to read.
I’d like to see the last 100 000 years in better detail
Periodic Ice Ages —> Glacial-Interglacial Periods
Major Period: —> 100,000 years; 9 degree F decrease
Minor Period: —> 12,000 years; 5 degree F decrease
Smaller Periods??: —> 1,000 years; 3 degree F decrease
We currently are nearing the end end of a small, minor interglacial period
Major Ice Ages: Most of the Planet is Covered Minor Ice Ages: 40 Latitude and Above Little Ice Age: (1000-1850 AD; Irish Potato Famine; Nisqually Glacier)
Here’s some theory: http://www.tgx.com/rockymountains/Iceages.html
Volcano connection? http://www.iitap.iastate.edu/gcp/influ/volcano.html
Are those numbers right?
There was some recent news item as well, some conference.
Is there anything missing? Any further crackpot theories?
I gotta go…
