Nor yet — though he might be closer to the mark here, showing how important it is to hedge your bets when predicting climate — are we in the midst of a «new ice age.»

The difference between the warming at the end of the last ice age (left side of the graph) and the current warming (right side of the graph) demonstrates how truly abnormal the current change in climate really is.

Although scientists dismissed how the filmmakers employed climate science (in the film the world enters an implausible new Ice Age), a slowdown in the current is certainly a theoretical possibility in the future.

HOW and WHY climate changes is obviously of scientific interest and, given the impact of a future ice age, of great societal importance also.

Now you need a really hard time to explain how this miniscule difference can trigger any ice age termination, especially if some researchers here claim that there is no excessive sensitiviy in climate to external conditions.

If you can't establish what the range of just the average global temperature is for the current climate optimum (since the last ice age), how can you begin to establish what the null hypothesis is, particularly as it relates to attribution of natural vs. anthroprogenic.

In a recent article in Climatic Change, D.G. Martinson and W.C. Pitman III discuss a new hypothesis explaining how the climate could change abruptly between ice ages and inter-glacial (warm) periods.

Besides demonstrating his firm grasp of the power of these various factors to change temperatures, this remarkable matching of theory to real - world data also tells us just how ornery the climate beast may be: the orbital changes that paced the ice ages were incredibly small.
