Climate Change in the Holocene Era.

I don’t pretend to be a climatologist, but I can read graphs. Even if the climate has been in a warming trend the last few decades, why should we think that would be terribly alarming or unusual? Climate alarmists like John Kerry say we have only a few years left to "save the planet from destruction". But even their apocalyptic forecasts are far below the temperatures of a few thousand years ago.
