In its recently released Fourth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 90 percent probability that human activities over the past 250 years have warmed our planet.
The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 379 parts per million in the last 150 years. The panel also concluded there's a better than 90 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50 years.
They said the rate of increase in global warming due to these gases is very likely to be unprecedented within the past 10,000 years or more

spindoc,

I agree that it's entertainment value that draws me here.

You might note that it's the "skeptics" who seem to think the blogosphere is the place to do the science, debunk the science and generally provide a "group-think" setting for their amateur hours.

I'm not attempting to do anything with the science in my spare time intermittently spent on OLO - I'm merely entertaining myself with addressing "skeptic" devices.

Secondly, when you check the BOM's ACORN temperature network, which is the BOM's premier state of the art temperature record and average the maximum temperature at all the ACORN sites on the 7th January 2013 the figure you get is:

35.91C

The BOM has produced a figure of 40.33C which is 4.42C more than their own records show.

The only problem is that your friend seems to assume that if the temperature is minus 30C at the poles and plus 30C at the equator then the average global temperature must be zero. in other words there is a bit more to than the simply adding up the temperatures at all the weather stations and dividing by the number of stations. You need to consider area as well.

Don't give us this sort rubbish it's embarrassing please try harder.

A bit of adverse weather preventing the dispersion of pollutants, and the residents of Beijing are reduced to getting about with masks to protect themselves.

"China's air quality is amongst the worst in the world, international organisations say, citing massive coal consumption and car-choked streets..."

Considering China produces nearly all of the West's goods these days, much of it superfluous, this is the West's pollution also.

Let’s start with warmair; no offence mate but you have lost the plot; what have the poles to do with the BOM’s ACORN network? The ACORN network, short for Australian Climate Observations Reference Network, is meant to be an Australia wide temperature system which reflects the climate of Australia. Are you really saying that extra information is needed when you say “You need to consider area as well.”?

What area!? The area between your ears! ACORN is meant to show the real temperature of ALL of Australia; that is what BOM said it would do.

All Ken did was use ACORN and show BOM couldn’t add up. Did they do that deliberately? Have they discarded ACORN after it was brought in last year because it didn’t give a record? One thing for sure is BOM’s own record doesn’t support its alarmist statements.

Poirot; so no one can now add up or divide or subtract temperature data, which is all Ken did, unless they are an approved, ie believes in the AGW scam, climate scientist? Is that what you’re saying; that intelligent and skilled non-approved people can’t comment on the climate?

Of course that’s what you’re saying. You’ll fit a Burqa real well with your outlook.

To put the lies and hysteria about the latest heatwave into perspective there is this:

‘Climate scientist’; in years to come it’ll be the worst insult you can make.

As for commenting on blogs; this ‘debate’ will be won and lost on blogs and through the media generally; that’s because it’s not about science but the corruption of science and you don’t need a PhD to know that.

So, stay entertained while you can Poirot; this won’t have a happy ending for your heroes.

Poirot your posts are becoming rather radical. More than a few are some what left of Khrushchev.

I'm not quite sure how you can blame the western consumer for the evils of the Chinese manufacturing industry. It is up to them what systems they use to produce the goods they rip us off with.

If anyone you would have to blame Greenpeace & WWF. They are the ones who's lobbying has led to the ridiculous restrictions in western nations, that make it uneconomic to produce our own goods, in our better controlled industry.

Pollution in China is one of the unexpected consequences which regularly flow from idiot green interference in things they don't understand. Like all those chopped & diced birds around those dreadful wind generators.
