My previous post suggested that an increase in the Chandler Wobble may stress the earth's crust and create more earthquakes, and in unxpected areas - such as middle England and central China on what should be stabler areas inside continental masses. Not only might that herald an impending magnetic reversal, but that in turn may have an effect on climates, as discussed on British Geological Survey's page also mentioned earlier.
Since last year too, debates have raged on how much climate change is man-made and how much is natural. Like in any natural phenomenon it's likely a combination of both. That still begs two questions:
- which came first, natural or human changes
- which has the greatest contribution of both
