A long, dusty drive to global warming...
Thinking about global warming (with Climate-gate being in the news), I remember visiting the amazing Roman ruins at Ephesus, an ancient city near the Turkish sea-side resort Kuşadası. It always struck me as odd that Ephesus had been a major port city that in 100 AD had a population of nearly half a million people and was second only to Rome in importance. Why odd? Because the ancient port of Ephesus is located more than 3.5 miles from the eastern edge of the present-day Mediterranean Sea. Somehow, over the last 1,900 years, the waters of the Eastern Med have receded and this onetime port is now a long, dusty drive from the nearest water.My conclusion from this? Our planet's climate has changed throughout history, on its own, without human intervention. Is it continuing to change? Absolutely. Is human activity contributing to these changes? Almost certainly. But do we know enough about climate science to understand what course these changes will take and how to influence them to our species' advantage? I sincerely doubt it.
