alright, let's see how I personally agree or disagree with the 'misleading arguments' from Alias's paper:
"Misleading argument 1:
The Earth’s climate is always changing and this is nothing to do with humans."
I clearly disagree with this, human industry emits a lot of gases and some of them have warming effects. But how big are those effects? Is that a preposterous question to ask? And the answer may be: not as big as previously (or generally) thought, and hey, the IPCC is starting (only starting) to agree with this, see my previous post
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1258870175/156#156 "Misleading argument 2:
Carbon dioxide only makes up a small part of the atmosphere and so cannot be responsible for global warming."
This is completely bullshit. I think you can safely neglect people who claim this.
"Misleading argument 3:
Rises in the levels of carbon dioxide in the atmosphere are the result of increased temperatures, not the other way round."
When applied to the present, this is also bullshit, although to be entirely correct I have to say that it is possible that a (likely minuscule) extra amount of CO2 has been released from the oceans by the warming, but as the deeper layers of the oceans are very slow to react to surface temperatures this is negligible. But at least I'm glad to see that this pdf acknowledges that during the ice ages the CO2 levels followed temperature, which is contrary to what Al Gore would have wanted us to believe (Bibs was asking about credentials, well, said person has none in the field and even gets prizes for that).
"Misleading argument 4:
Observations of temperatures taken by weather balloons and satellites do not support the theory of global warming."
This is again a baseless argument (and I don't have the impression anyone is using it nowadays). What is relevant is the last paragraph, which talks about something I have been talking repeatedly but ghenghisclown chose to simply ignore this, together with a lot of other remarks I made and which I think are still relevant, if I'm wrong on all these points (do I really have to repeat them all?) you might as well let this know. So, the last paragraph:
Quote:It is fair to note that in tropical regions of the world there are still some discrepancies between what computer models lead us to expect regarding temperatures at the surface and in the troposphere and what we actually
see. However, these disagreements are within the bounds of the likely remaining errors in the observations and uncertainties in the models.
Firstly, it acknowledges the problem of a missing tropical hot spot I have been talking about, secondly, it says the observations are within statistical error bounds, but although it might be true (and even that is not clearly the case) that the data are not
disconfirming the models, they certainly do not confirm it. You can read a discussion of this at
http://wattsupwiththat.com/2013/07/16/about-that-missing-hot-spot which gives references to both view points.
"Misleading argument 5:
Computer models which predict the future climate are unreliable and based on a series of assumptions."
I agree that the models used by IPCC are unreliable, which they themselves are starting to admit! Things like "Modern climate models have become increasingly accurate in
reproducing how the real climate works" are bullshit, they didn't predict the current halt in global warming at all.
"Misleading argument 6:
It’s all to do with the Sun – for example, there is a strong link between increased temperatures on Earth and the number of sunspots on the Sun."
It certainly has not all to do with the Sun. Stating that there's a strong link betwees sunspots and temperatures is debatable, there certainly isn't a direct link (except a minuscule change in solar luminosity). The discussion in this part about aerosols causing some cooling about 1970 doesn't seem impossible to me but that still doesn't mean the Sun can't have had some impact too.
"Misleading argument 7:
The climate is actually affected by cosmic rays."
I think this is indeed perfectly possible and the article actually says that an effect on climate by cosmic rays is possible, and likely to be small. But even if it is small, climate is still affected by it, so this so-called misleading argument might be simply true, according to this very article. More research on cloud formation is needed here.
"Misleading argument 8:
The scale of the negative effects of climate change is often overstated and there is no need for urgent action."
I certainly tend to agree with this, at least when it comes to urgent action because of climate change.
So several of these misleading arguments are indeed misleading.
