In Search Of - The Coming Ice Age


(8:47)

The recent cold weather has reminded me of the fact that we are living in an interglacial period.

Although we are pumping tons of carbon into our atmosphere, which I don't think can be a good thing, Ice Ages are thought to occur due to the heat coming from the Sun. The Sun's intensity waxes and wanes as part of its natural cycle and there's nothing we can do about it. At present the sun is waning. Furthermore, NASA has determined that the upper atmosphere has cooled somewhat in recent months. So rather than warming, we might see a period of global cooling.

Having said that, it is still a good idea to make plans to lessen our impact on the environment in the expectation there will be no immediate return to a glacial period. Clean technology is good from a pollution and sustainability standpoint.
