It's "the biggest collaborative science project in human history" part that worries me.

Plenty of the usual childish invective so far, but no answer to David Solomon's final challenge.

Note Liam's use of what Bjorn Blomborg described as "the litany" or list of issues that supposedly prove something but in fact are still subject to major debate. He said, "never mind that co2 conc/ocean temp/ocean acidity/glacial melt/species migration/weather records all provide concrete proof that biosphere is changing fast and emissions are playing a big role".

But mean temperatures of the upper 700m of ocean has only increased by 0.10C over the past 50 years and the original sea level rise scarenarios have now crawled back into a very small IPCC hole. Ocean acidity is only an issue in the north atlantic while there has been minimal change in the remaining 85% of ocean volume. Glacial melt has since been found to occur in spasms and the ones that had speeded up in the past decade have now almost stopped. And species migration and weather records have just been thrown in to pad up the list to make it appear more substantial. Much ado about nothing really.

Perseus: Bjorn Blomborg?!? Suspect you're thinking of Bjorn Lomborg, the political science academic working as a statistician who pretends to know something about climate physics

At least he's not another lawyer! You may claim the factors i listed are in dispute and we should continue 'growth'-as-usual, but i disagree with your unevidenced claims on the data.

Ocean warming to date is much closer to 0.5C, and that amounts to a huge mass of water, phenomenal amount of heat. http://www.oceansalive.org/explore.cfm?subnav=article&contentID=4704 "For one, ocean surface temperatures worldwide have risen on average 0.9 degrees Fahrenheit, or 0.5 degrees Celsius, and ocean waters in many tropical regions have risen by almost 2 degrees F (1 degree C) over the past century. This is 30 times the amount of heat that has been added to the atmosphere, a significant amount even though the ocean has a lot more mass than the atmosphere."

Sea level rise forecasts in IPCC 4thAR only fallen on an apples to banana's comparison

A common mistake for those who skim the data with one eye open.

Are you ready, Steve? Aha. Andy? Yeah! Mick? OK. Alright, fellas, let's go!

Oh, I see a man at the back
As a matter of fact his eyes are red as the sun
And a girl in the corner let no one ignore her
'Cause she thinks she's the passionate one

Oh, yeah, it was like lightning, everybody was frightening
And the music was soothing, and they all started grooving

Yeah, Yeah, Yeah, Yeah, Yeah
And the man at the back said
Everyone attack and it turned into a ballroom blitz
And the girl in the corner said
Boy, I wanna warn ya, it'll turn into a ballroom blitz
Ballroom blitz, ballroom blitz, ballroom blitz
Ballroom blitz.

I like the way The Lord Mayor of Sydney was in New York at a climate summit the other day and touted the 1-hour lights out as a raging success.

She suggested that every city in the world should do the same some time, at the "same time"

Can you imagine New York agreeing to that at morning or afternoon peak hour? Imagine Hong Kong or Tokyo at morning or afternoon peak-hour turning off their lights or surplus energy. Imagine London or Paris at morning or afternoon peak hour.

Some cities in the world would have to sacrifice a peak hour if Clover Moore gets her own way. Of course, Sydney is so important, we will get to set the time for all cities to synchronise?

Sydney is not really as important as it sees itself.

I'm sure they clapped politely to Clover Moore in New York and politely scrubbed her name off the list from any credible Delegate.
