Pity. If you ever come across a showing or have access to "Little Ice Age - Big Chill" make sure to watch it. It's very interesting historically how the cooling climate affected the already-turbulent history of Europe. For instance, global cooling was largely influential in causing the French revolution!
In this case the extinction rests with the fact that all these germs etc are encased in ice. Scientists already acknowledge that they will return once they thaw out. There are organisms which can live in thousand degree water at a heat vent. There are germs in the atmosphere were the temps are way below freezing and germs can live in outer space. I'd say that is enough proof except for an extreme skeptic/cynic.
Well if the germs etc. still exist, whether they are encased in ice or not, they aren't extinct. And do we know they're there? Or (more likely) did someone just make that up and speculate that they would we unleashed on an unprepared world by melting?
Where is the extra water going to go once the land based ice caps melt? I sure as hell wouldn't want to be living in Holland, that's for sure.
Well, the land based ice caps aren't melting. It's well known that when the Norse colonized Greenland it was much warmer, the southern part of Greenland was lush and green, and they farmed there. Can't do that there now, not near warm enough yet. But although ice at the southern end of Greenland is melting, the rest of it is increasing as increased snowfall due to warmer air(which can hold more water) adds to it every year. Similarly, while the Palmer peninsula of Antarctica is melting, the rest of the continent is increasing its ice cover by 2 inches per year for the same reason. Besides which, even if it did melt, it would take many thousands of years to happen.
Interestingly, the pre-industrial era that alarmists are so worried about warming up from was the coldest time of the last 8000 years. It was a time of extreme misery, starvation, disease and war. Why would anyone not want to warm up from that?
