According to an analysis of core samples, the southern ice shelf reacts far more sensitively to warming temperatures than scientists had previously believed. The message: sea levels may rise even further than feared. spiegel.de ================== Climate Change Impact More Extensive than Thought By Volker Mrasek Global climate change is happening faster than previously believed and its impact is worse than expected, information from an as-yet unpublished draft of the long-awaited second part of a United Nations report obtained by SPIEGEL ONLINE reveals.

Wharfie, ppm isn't a pressure. <At 20,000 ppm, most people are unaware of the CO2" What's that in mmHg? > In air, at 15 psi, there would be a partial pressure for CO2 at 20,000 ppm, but I have no idea what it is, measured in inches of mercury, or millimetres, or kilopascals. Google probably knows if you are curious. Air has gone from lows of 200 ppm to a high now of 380 ppm with an increase in the last 60 years [production wasn't that much before then] from 320 ppm about. I don't think your patients will be worrying about 60 ppm difference. You'll get that much difference by having windows shut on a cold day [I guess], though a chimney would suck a lot of fresh air in [not that fresh in some instances - when everyone has fires going, the air is disgusting].
