Therefore at least some of any early ice and snow
melt in the NH must be due to AGW,
yet in justifying his theory he wants to count it all as a consequence of
seasonal drift in insolation.
RE: 4th Error -RCB- Poses an objection to the non-scientific term catastrophic [NOTE: Scientific «consensus» is often being used & / or implied in standard climate - change discourse -
Yet Consensus is a Political Term - NOT a Scientific Term]- HOWEVER - When Jim Hansen, the IPCC & Al Gore, et - al - go from predicting 450 — 500 ppm CO2 to 800 — 1000ppm by the end of the 21st century -LCB- said to the be highest atmospheric CO2 content in 20 — 30 Million YRS -RCB-; — & estimates for aver global temps by 21st century's end go from 2 * C to 6 * C to 10 * C; — & increased sea level estimates go from 10 - 20 cm to 50 - 60 cm to 1M — 2M -LCB- which would totally submerge the Maldives & partially so Bangladesh -RCB-; — predictions of the total
melting of the Himalayan Ice caps by 2050, near total
melting of Greenland's ice sheet & partial
melting of Antarctica's ice sheet before the 21st century's end; — massive crop failures; — more intense & frequent hurricane -LCB- ala Katrina -RCB- for much longer
seasonal durations, etc, etc, etc... — IMO That's Sounds pretty damned CATASTROPHIC to ME!
