Geographers define an ice age as a period in the Earths history when there are ice caps. Our current climate is an 'interglacial' period. This doesn't mean 'between ice ages'. It is used to describe the period within an ice age when the ice retreats because of warmer temperatures.
'Our' interglacial started 10,000 years ago, in what we think is the Fourth Ice Age. FOURTH!
An interglacial period ranges from 12,000 to 50,000 years.
The causes of the fluctuations are not well understood. Possible factors include the position that the land masses happen to be in, the composition of the atmosphere, changes in the planets orbit around the Sun and possibly even the Sun's own orbit around the galaxy.
The 'Little Ice Age' which began in 1500 and lasted for 300 years, saw the average temperature in northern Europe drop by 1 degree Centigrade. It also coincided with a period of extremely low sunspot activity. Who did the government blame then, when it eventually melted?
We are being conned.
