The climate, and hence weather patterns, have always changed as the Earth is a dynamic system.
Whether we, as that animal species homo sapiens, are the cause of the present apparent exacerbation is open to debate.
BUT it is bleedingly obvious that we are not doing it or ourselves any favours by continually dumping millions of tonnes of pollutants into the atmosphere.
You can indeed have too much of a good thing.

Jennifer play book comes straight from creationist tactics. Taking pot shots at Brian Cox how sad. Creationist produces mountains of material just like you.
You couldn't convince your fellow scientist in the scientific world so you joined the IPA. Not an organisation well know for it's contribution to scientific progress. A nice little group think tank interesting in swaying opinions not advancing science, just like creationist.

Why not actually address the Senator's comments Jennifer, do you believe that there is a world wide fraud going on regarding climate science. That government and private organisation are deliberately changing data to support their findings. Yes or No

Oh for those playing at home here is a link to Richard Horton's comments to put them into their proper context.

I think Jennifer goes too far. Of the three ‘misleading’ claims of which she accuses Brian Cox, only one is really relevant, the global temperature chart. This she describes as “an out-of-date NASA chart of remodelled global temperatures as proof that we have catastrophic climate change caused by industrial pollution“. Well, it’s true that the chart appears (it’s hard to tell from the fuzzy Q&A screen shots) to go only as far as about 2010, but there are other later versions in which the short time extension makes no difference to one’s reading of the chart. No problem with the chart. Temperatures are rising.

‘Remodelled’ is a loaded term. What climate scientists have done, as far as I can tell, is integrated the satellite data available from the late 1970s with earlier measurements using good old thermometers and the like. What else could they do? Not models. Measurements.

The sad thing is that there is no need to exaggerate the case as Jennifer has done. Global ‘land – ocean temperature index’, which is what Brian Cox displayed, is definitely rising. Physical chemists, like me, are predisposed to blame rising carbon dioxide levels and the resulting changed spectral properties of the atmosphere. There might be other explanations. In normal circumstances we could surely give climate scientists the job of sorting them out. These days we just need to make extra sure that their peers are free to publish critiques. Has there been a ‘catastrophe’? Or is there one looming? That’s where Jennifer should concentrate her criticisms because she will lose credibility on her other grounds.

Just look at Cox’s chart. Temperature went up by close to one degree Celsius in the century to 2010. Catastrophe? In the absence of all the panic and exaggeration about future global warming, a scientific paper in 2011 announcing such a finding would have been met with a giant yawn.

The real problems are the alarmism of global environmental pessimists and the ridiculous energy solutions they so optimistically put forward. That’s the weird paradox. That’s where Jennifer could make a difference.

Let us not forget the Y2K scam. The hole in the ozone layer which an Australian scientist explained at the time was caused by the lack of sunlight over the poles in winter. CFC's were banned but are still produced in larger quantities by Russia and India so?
This sort of scam by thieving lying scientists is the reason I do not believe in spending money on a nebulous theory that tells me it is getting hotter. Really?
I believe a Royal Commission should sort this out and then the real day of reckoning where public servants are dismissed without a pension and have to pay damages.

JBowyer,
Just because the Y2K bug did not cause any serious problems doesn't mean it was a scam.

The lack of sunlight over the poles in winter prevented more ozone being formed, but that alone wasn't enough to cause the hole. That was caused by chlorine monoxide catalytically destroying the ozone, and the chlorine monoxide was the result of sunlight breaking down CFCs in the stratosphere.

Thanks to the Montreal Protocol, CFC manufacturing has ceased though China and India still have large stocks of them. The phaseout of HCFCs is much slower, and they won't be eliminated completely until 2030.

Global warming is not a nebulous theory. We know for sure that CO2 absorbs more ore the infrared radiation produced by the ground when the sun heats it. It's even been confirmed by Mythbusters. And we know from temperature measurements that warming has occurred, last year was the hottest on record, and the pause never really existed – it was just an artefact of cherry picked data.
