The myth is that the earth's current warming is due to a 1500 year cycle observed in the ice cores of greenland then the ocean sediments in the Atlantic.
This theory supports a temperature "see-saw" effect that the total heat on the globe remains constant. This was drawn from the above mentioned ice core data. However, there has been a dramatic increase in CO2 concentrations in the atmosphere in these last 200 years. For the previous 800,000 years, it remains under 300 parts per million but has now reached 400 ppm in the span of these 200 years. Unlike natural variations in heat, this human produced warming is being recorded all around the globe, in the oceans, air, and on the ground.
