The current warm period is no “anthropogenic product”, rather it is the
natural result of a repeating 1000-year cycle that goes back far into
the past. Today’s warm period does not even reach the temperatures seen
in the past warm periods, which at times were 1 to 2°C higher. Moreover
it is important to note that during both of the past temperature maxima
of 1000 and 2000 years ago, the CO2 values were at 280 ppm while today
they are at 400 ppm. This indicates that the earlier warmer periods
likely were related to natural solar activity and not to a rise in CO2
because there was no CO2 rise during those warm phases."
