A quick review of 13 dates from previously identified  Global warm and cold periods going back almost 3,000 years gives these average dates for either the bottom or the peak temperature in that period.

The Sub Atlantic Cold Period 363 BC

The Roman Warm Period 365 AD

The Dark Age Cold Period 700 AD

The Medieval Warm Period 1192 AD

The Little Ice Age 1602 AD

The average peak to bottom for these observed Cycles is 491 years or 982 years for a complete cycle. So if we add 491 years to the last bottom which was in 1602 AD that would make the peak of the “current” warming trend 2149 AD This has nothing to do with CO2 although CO2 will add some to the coming peak maybe even 1 degree Celsius.

Basically what this quick 30 minutes study showed is there is nothing to worry about except corrupt politicians.
