GLOBAL-OVERHEATING DATA FAR WORSE

This blog has predicted at times that higher predictions for global-overheating would be coming at us, and that they would be much higher than the official nonsense coming from the Intergovernmental Panel on Climate Change (IPCC) and various 'scientific' head-in-the-sand optimists.

And come they have, this time not from computer models, but studies by different teams of different sets of historical data. The results, summarised in this BBC News page show that we can expect a rise of at very least 5.8 degrees Celsius by 2100, probably at least 7.7 degrees, or much more. That means the worst scenarios predicted by the distributed-computer modelling, which have also been referred to before in this blog, are most likely to hit us (see NewScientist, or here, copied from the Independent), which show temperature rises of up to 14 degrees in the Amazon, perhaps 20 degrees in the UK, and a global average rise of up to 11.5 degrees. The climate on this planet is going to go pear-shaped in the nastiest way, and still no one wants to DO ANYTHING.

In the same group of news pages the BBC also reports a study showing that the populations of migratory birds are plummeting, and have been for thirty years. But no one noticed till now. Are these more 'canaries' going down the world's coal-mines? Are these birds yet another vanguard suffering the consequences of the chronic insanity of burning black stuff?

Whatever the truth of that, and if it is just coincidence the odds against it must be high (and we can certainly blame human activity of some sort), the fact remains that global overheating predictions are inching towards the worst-case scenario predicted by the extreme computer modelling such as that cited above--which is no surprise because it fits the way the actual readings are tracking.

For New Zealand, which now has an annual mean temperature of 13.1 degrees Celsius, that would mean a virtual doubling of temperatures. A balmy 20-degrees in the shade would on simple arithmetic become a torrid 40 degrees. A hot 30 would become--who knows--60 degrees? It does not bear thinking about. If so, it would exceed the world record temperature of 57.8 in the shade set at Al Aziziyah, Libya in September 1922. An average in the mid twenties for New Zealand would not be nearly as bad as the world's present worst annual mean of 34.4 degrees in Dalol, Ethiopia, but it would be plenty hot enough. In some ways it would be worse, because it would be a more humid heat in a country surrounded by oceans.

There would be no snow on New Zealand mountains, so precipitation would fall as rain, causing horrendous floods in winter; and there would be no snow-melt in spring and summer, causing dire droughts.
