Has anyone been talking credibly about a new ice age since the days of atmospheric nuclear testing and fears of nuclear winter? That's back three, four decades ago? I'm convinced climatology, remote sensing, and our ability to scientifically computer model changes has taken our understanding of global systems (and our forecasts) to a higher level, but your post makes me think of the album cover to Jethro Tull's LP, Stormwatch. The world has moved on, hasn't it?
