Nevertheless, some components of the climate have very long characteristic times, so it could be many decades, or even hundreds of years before effects show up. By which time it would be too late to back out. One such long term item is the cycle time of the deep ocean currents. [snip] Regards, Robin van Spaandonk All SPAM goes in the trash unread.
