The New Zealand Government's climate change legislation has been passed into law.
“The Climate Change (Emissions Trading and Renewable Preference) Bill has implications for every household and the potential to change the make-up of the labour force as environmental factors gain increasing importance in business. It will eventually bring all sectors of the economy under a regime which sets limits on the amount of greenhouse gas they can emit. Those that breach their limit will have to buy credits from those that are below their cap. Electricity comes under it in 2010, transport in 2011 and agriculture in 2013.
"Climate Change Minister David Parker launched the third reading debate, saying he was proud New Zealand had risen to meet the greatest challenge facing the world.”

It appears the AGW proponents disregard or fluff water vapour in their calcs.
The other inconsistency is they claim it is getting warmer. At first glance the weather stations do not seem to indicate this.
Looking at the monthly record highest temperatures where I live in Sydney, it appears the record highest temperatures were in the distant past.
If there is global warming occurring you would expect it to be getting hotter with the highest temperature readings increasing by now. This doesn't seem to be happening.
A quick perusal of other long established weather stations where the immediate surrounds have not been altered to cause a heat sink island, shows no indication of any recent warming temperatures, or any recent increase in the highest temperatures.
MELBOURNE
HOBART
The other capital cities do not have long established weather stations, as these have been close or moved.
I have included a few regional ones;

The readings seem to indicate it was warmer in the past, am I missing something?
Thanks, Tony, for pointing to

which I had not seen before, and found to be a great summary of some of the key information.
Yes, it is difficult comprehend how they can rank carbon so highly.
Whether water is 75% or 97% there is still a hell of a lot more water than the carbon.
Maybe these links are a more accurate portrayal than Wikipedia;

Tony G...please be advised that Wikipedia is edited by a contributor to realclimate, William Connolly, a computer programmer. The figure that CO2 contributes 9 - 26% of the greenhouse effect sounds like it came right out of RC. It's highly unlikely that a gas whose density is 38 molecules to 100,000 of air could have that impact. Lindzen calims water vapour accounts for 97% of the GH effect.
Thanks Steve noted, although Wikipedia could be a more reliable reference source than the IPCC.
It is hard to work out what practical implications will result from the NZ legislation, so we will wait and see what happens. I can not find “all six major greenhouse gases” they refer to and it is unlikely they will want to kerb water vapour emissions.
It is just my (somewhat off topic) personal view that the AGW proponents have all but ignored the largest single contributor to the the greenhouse effect 'water vapour' in their hypothesis, this IMHO is a major flaw in their argument.
