That sounds dramatic except that the temperature in most places spikes 22 degrees every day, and much more between summer and winter, and not much dies off from it.
1) 14,000 years ago, or even 11,000 years ago - man was not contributing to global warming gases (if you consider the 0.28% that we DO contribute as a real factor - I don't).
2) We are in a WARM period RIGHT NOW. A relatively long warm period (thank goodness for civilization). We ARE coming to a turn in the road if the past cycles hold true. And based on the past information, it would be a turn downwards (in temperature). We're going to be caught with our pants down trying to stop global warming, when instead we should be preparing for all types of climate change. (Hot, cold, wet, dry, ....) Of course the best way to rapidly adapt to that is the old fashioned entrepreneurial way - not some plodding government program.
