It seems by all accounts that Planet Earth is cooling and has been for the past ten years. However, those who believe in man-caused global warming insist this is an anomaly, and the overall trend is still one of warming. Well, of course they have to say this. The premise behind the idea that man's activities are bad for our climate is based on the notion that carbon dioxide emissions are greenhouse gases and cause global warming. If that basic premise proves to be false, or falls short of the predictions, the whole global warming/climate change house of cards falls apart.
That collapse is what I see happening, but the true believers will drag out the old fears, distort the data, and try to influence people's thinking for as long as possible. Read the following article and consider the "double-talk"; the climate is cooling, but overall, it is warming......yes, but it is all perfectly natural and they can't prove otherwise, so they have to resort to "slight of hand" trickery. Witness the recent initiation of Al Gore's $300 million advertising campaign. They want to milk the global warming scare for as long as they can.
Global warming 'dips this year'
By Roger Harrabin BBC News environment analyst
Global temperatures will drop slightly this year as a result of the cooling effect of the La Nina current in the Pacific, UN meteorologists have said.
The World Meteorological Organization's secretary-general, Michel Jarraud, told the BBC it was likely that La Nina would continue into the summer.
This would mean global temperatures have not risen since 1998, prompting some to question climate change theory.
But experts say we are still clearly in a long-term warming trend - and they forecast a new record high temperature within five years.
The WMO points out that the decade from 1998 to 2007 was the warmest on record. Since the beginning of the 20th Century, the global average surface temperature has risen by 0.74C.
LA NINA KEY FACTS
La Nina translates from the Spanish as "The Child Girl"
Refers to the extensive cooling of the central and eastern Pacific
Increased sea temperatures on the western side of the Pacific mean the atmosphere has more energy and frequency of heavy rain and thunderstorms is increased
Typically lasts for up to 12 months and generally less damaging event than the stronger El Nino
La Nina and El Nino are two great natural Pacific currents whose effects are so huge they resonate round the world.
El Nino warms the planet when it happens; La Nina cools it. This year, the Pacific is in the grip of a powerful La Nina.
It has contributed to torrential rains in Australia and to some of the coldest temperatures in memory in snow-bound parts of China.
Mr Jarraud told the BBC that the effect was likely to continue into the summer, depressing temperatures globally by a fraction of a degree.
This would mean that temperatures have not risen globally since 1998 when El Nino warmed the world.
A minority of scientists question whether this means global warming has peaked and argue the Earth has proved more resilient to greenhouse gases than predicted.
But Mr Jarraud insisted this was not the case and noted that 2008 temperatures would still be well above average for the century.
"When you look at climate change you should not look at any particular year," he said. "You should look at trends over a pretty long period and the trend of temperature globally is still very much indicative of warming.
"La Nina is part of what we call 'variability'. There has always been and there will always be cooler and warmer years, but what is important for climate change is that the trend is up; the climate on average is warming even if there is a temporary cooling because of La Nina."
Adam Scaife, lead scientist for Modelling Climate Variability at the Hadley Centre in Exeter, UK, said their best estimate for 2008 was about 0.4C above the 1961-1990 average, and higher than this if you compared it with further back in the 20th Century.
Mr Scaife told the BBC: "What's happened now is that La Nina has come along and depressed temperatures slightly but these changes are very small compared to the long-term climate change signal, and in a few years time we are confident that the current record temperature of 1998 will be beaten when the La Nina has ended."
