Well, just how long have we humans been keep accurate accounts of weather? In the span of time the planet has existed, regardless of the Biblical account of about 6000 years or the quantum theories that say 'billions and billions' of years, we have recorded weather history in detail for about 10 seconds! Think of that... we really have not a clue of what is really 'normal' in weather. That is to say 'computer models' that practically all the predictions are based on are really based on far less than 'good input'.
In the 70's we were told we would have a new ice age in about 20 years, today the gurus that have been hollering about 'global warming' are befuddled that the Earth's temperature has acutally averaged -2°C since 1992!! DUH!? Understand this, no one can predict weather, we can garner and predict with some degree of accuracy of what might happen in the very short term by looking at what is happening now, i.e. warm and cold fronts and such but that is about it.
There are far to many variables, solar flares to be specific for one, that have HUGE effects on the weather of this globe that no one can predict.
Is it unusual for the earth to have this current pattern of weather? We simply and honestly HAVE NO IDEA!
