"If I 'predict' that the weather is going to get warmer over the next month yet give inaccurate predictions that doesn't mean that the trend is incorrect."
Ahhh yes it does...you predicted it was going to get warmer and it didn't...therefore the trend is either negative (opposite trend) or nil. Also Kevin Trenberth didn't say GCM's are not predicting the weather, he said climate. How often have you heard the argument from the warmers that weather and climate are different. In fact to quote realclimate.com "Although ultimately chaos will kill a weather forecast, this does not necessarily prevent long-term prediction of the climate. By climate, we mean the statistics of weather, averaged over suitable time and perhaps space scales (more on this below)."
This statement is a nonesense as well, as chaos will ultimately kill a long-term prediction as well.

"They can only operate with 'if x goes on then y is the likely result'. Anything else would simply not be good science."
Actually I think Kevin Trenberth is saying that 'if x goes on then y MAY result'

I think you may need to re-read the article Lev.

"GCMs 'assume linearity'"
This is another frightening admission. When was the global climate system ever linear? I may have just as well used my ruler and drawn a temperature trend line from 1900 and projected it to 2100. The result will be just as likely as the GCMs. Should we change our lifestyles on my hand drawn trendline?

"Evolution might not be a myth but it is a hopelessly discreditted scientific theory."
runner is bible basher..look out!

The politically motivated scare campaign on climate will eventually be proven to be a gigantic hoax.

Unfortunately, the con trick will run long enough to enable the social engineers to gain more control over a docile, gullible population, and increase the wealth of energy providers who will use the permission given to them by governments to jack up their prices in the name of development of 'climate-friendly' alternatives, which don't exist and which are not needed anyway.

Climate change there may be, but anyone who tells you it is man made is a confidence trickster, and you will be forced to pay dearly for your electricity and water merely to put more of your money into the pockets of big business - mainly foreign controlled.

Weather forecasters cannot even tell us whether or not is is safe to put out the washing tomorrow; yet we, fools that we are, believe their wild predicitions for 50 years hence!

Apart from the money-making opportunities of climate change scare-mongering, there is also the opportunity of moving closer to world government - we must all get together, must we not, on the "greatest threat to mankind"

Apart from the fact that linearity in climate change means linearity in time series. An example of comparative time series can be found in the following PhD thesis on http://www.hydromap.com/publications/ames_thesis_complete.pdf. The suggestion of "use a ruler and draw a temperature trend" by the professor is remarkable dishonest.

@leigh

You're quite right. The One World Government black helicopters are coming for YOU. Keep your tinfoil hat secure, or the orbital mind-control lasers will get you!

Bob,
Could you please email your piece to the 1,600 scientists half of whom are Nobel prize winner in their field who presented a report to the UN in 1991 telling us what was to come. Prolonged droughts! more severe Hurricanes/Cyclones, Katrina, Larry etc. Bob you're the best mate, all that knowledge [more than 1,600 combined scientists] and nowhere to put it except here, oh by the way Bob I've heard the Earth is flat, is that true?

Wrong SHONGA. Only 787 Nobel Prizes have been awarded in all fields since 1901.

Richard,
Thanks for the nit pick the fact remains some of the 1,600 scientists had a Nobel prize, the balance were leaders in their fields. Why do we educate children to become doctors? When we are ill we seek their advice.

Other intellegent people go on to become scientists who create medical break throughs, we believe them. However as soon as the scientists give us the truth that we don't want to hear, all of a sudden they are a pack of raving ratbags.

Obviously vested interests are at work trying to discredit the work of the scientists, my only vested interests are my children, and their children. If someone can produce scientific proof that we don't need to act urgently to save the planet, let them come forth, no I thought not.
