We know that the Earth's magnetic poles never stop shifting and that has been taken into account in navigational charts for decades. Whether the Earth's 'true' poles - the axis upon which they spin - is changing I don't know. However, we're all pretty well accepting that the Earth is heating up. Only a few recalcitrant 'rednecks' hang onto the idea that everything is as it normally is.
Here in Sydney, Australia, we've had our longest spell of warm autumn whether since records began being kept. Remember, we're in the Southern Hemisphere, so May is autumn not spring. By this time of year it is generally getting quite cold. However, this year it isn't. The ski season opens in only a couple of weeks and there is no snow whatsoever on the ski-fields of our so-called Snowy Mountains. The ocean temperature around the NSW coast is only one degree colder than it was in mid summer.
No doubt the Earth does have its normal, ever-changing phases. We know of the Ice Ages of the past. But it would be naive indeed to think that we human beings are not simply stuffing up the planet on which we live. It's been going on for a long time, of course, but it's only the last twenty or so years we might have reached a tipping point that cannot be reversed - well, not unless drastic action is taken to reverse what we're at present doing.
