Question

What melted the Ice Age glashers, Global Warming or heat realease from earth?

Answer 1

Warming of the overall average global temperatures, which is a natural and cyclical process.

Answer 2

As a geologist, I learned that the earth is actually a pretty good insulator due to its thickness of thousands of miles.  The heat released by the earth at the surface is small compared to the heat generated from the sun.  

Answer 3

In the past, other activities were more important include the variability in the heat given off by the sun and the distance from the earth to the sun along with patterns of pollution from volcanos and large meteor strikes.

As one example, you could ice skate in the Thames in the 19th Century and at the time of Stonehenge the climate was quite warm.

Answer 4

Global warming melted the glaciers, and we are still in a warming cycle. Warming is good.

Wait till the cycle reverses and it starts getting cold, that is when you want to start to worry.
