When one looks at temperature charts for the last 10.000 years, one immediately notices that swings become a lot more frequent and the curves are not long and smooth anymore but rather erratic and volatile. That leaves the impression that temperature changes in the past took a lot of time to materialize and now they are becoming faster. When in fact the volatility of recent times only results from much more data density that we have. We can only make estimates for what the temperature has been during the Minoans. The changes were always there – we just did not measure it.
Abrupt changes in ice core samples and other records indicate dramatic changes in climate occurred at certain points in the past.
