What Thawed the Last Ice Age?

In his excellent lecture on the events that happened at the end of the last glaciation period, some 10000 years ago, Randall Carlson points out the enormous energy required to melt the ice sheet then covering a large area of the northern hemisphere.

This ice sheet which covered all of Canada and all of Northern Europe, as well as vast areas in Asia, disappeared in a matter of a few thousand years. The energy required to do this would have been enormous. So much so that it is completely unclear where it may have come from.

Randall's own conclusion is that the energy must have come from outside our solar system, but he gives no further suggestion to a source. From looking this up on the internet, the mainstream thinking quite predictably suggests that it must have been due to a sudden, inexplicable, rise in CO2.

However, a third possibility should also be considered. The energy may have come from inside our planet itself. If our planet is expanding, as I believe it is, then the crust of our planet is growing thinner. Whatever heat that is stored inside our planet will find its way out more easily during periods of expansion.

Noting that gravity appears to have increased during the exact same time that the ice sheets disappeared, we have further reasons to believe that the two events are related.

Some of the animals that went extinct at the end of the last glaciation period are impossibly large for our current gravity. They could not exist today, even if they had survived whatever immediate event that killed them off.

The reason for the expansion that triggered all of this is most likely a change in the electrical environment of our planet. We know from Henrik Svensmark's work on cloud formation that our planet enters and leaves areas of cosmic radiation with regular intervals. Furthermore, geological activity is linked to this, which in turn implies expansion of our planet.

Our planet expands, gravity increases and temperatures rise, all due to cosmic radiation.

Similarly, the start of glaciation periods, are linked to cosmic radiation, geological activity, and cloud formation. However, the heat reservoir inside our planet is in those cases not released. Our planet may even shrink a bit as pressures are released without expansion.

The exact mechanism appears to be complex. However, in general, glaciation starts with increased cosmic radiation, increased geological activity, but no expansion. It ends with decreased cosmic radiation, increased geological activity and expansion.

It is the change in cosmic radiation, rather than the absolute amount of it that causes abrupt geological activity, while it is the absolute amount of cosmic radiation that determines the amount of cloud cover and precipitation.

Finally, it is the expansion that releases the heat that melts the ice sheets. This is the same expansion that causes gravity to increase.
