On ‘belief’ and ‘denial’ : Comments

By Don Aitkin, published 27/12/2012

Further, the doomsayers accuse old-fashioned empiricists like me of being 'deniers' or 'denialists' because we do not accept their faith.

cohenite, Raycom, prompete et al,

Never mind about the Hobbit. I recommend the following for your viewing pleasure (you might learn something too) I've provided the popcorn and cool drinks - so sit back and enjoy.

From there being no such papers, suddenly there are seven.

You could have claimed magician status had Cohenite not butted in to spoil your act.

Seriously though, as we would be wasting our time chasing up your references, would you be so kind as to inform us of the specific measure(s) of human influence on global warming that have been quantified therein, should you still consider that they contain the goods.

There you have it, folks...

Raycom is provided with references to that which he seeks - and he "chooses" not to pursue them. Apparently his repeated requests for such information (all this time) have been nothing but empty blather.

Says it all really.

The denialistas keep on coming up with sites that "prove" this or that, please just look out of the window. You will see that the arctic ice is disappearing, glaciers are shortening, temperatures are trending up, the Antarctic is losing sea ice, the Greenland icecap is rapidly melting.
Please just look out, away from all the so called experts and have a look at the real world.

That’s right Poirot.

On a related note, scroll down to Vaillant’s categorisation of defence mechanisms:

http://en.wikipedia.org/wiki/Defence_mechanisms

Levels 1, 2 and 3 – take your pick.

Ciao

Warming and attribution. I agree that the planet seems to have been warming, but we can't measure the extent very well (despite all the numbers thrown around). But warming is not the issue, really. It is attribution of the warming. There is abundant conjecture about that, but no real hard evidence of the extent to which it is due to human activity.
_________________________________________________________________________________________
With all due respect we have plenty of evidence that greenhouse gases are the cause of the obseved warming.

We can make a pretty good estimate of the likely effects of any particular type of warming trigger. Global warming as a result of GHGs leaves a very clear fingerprint, which is quite different to other types of potential warming trigger. For example if the warming was caused by an increase in solar radiation we would get more frequent higher maximum temperatures, and summer temperatures would increase faster than winter temperatures. In reality we see the exact opposite with night time temperatures increasing faster than daytime temperatures and winter temperatures rising faster than summer temperatures.

Here is a short list of effects which are point to GHGs as the most likely cause of the warming.

1 The surface is warming on the other hand the stratosphere is cooling.
2 Night time minimum temperatures are increasing faster than daytime maximums
3 winter time temperatures increasing faster than summer temperatures.
4 Poles are warming faster than the equator.
5 The atmospheric boundary between the troposphere and the stratosphere has risen several hundred meters over the past 3 decades.
6 Increased ocean heat is not consistent with other potential heat triggers such as solar.
7 Observed changes in air pressure at sea level are consistent with warming due to GHGs.
8 Precipitation predictions are more consistent when the effects of GHGs are included.
9 Increased levels of infra-red radiation have been observed at the surface at a number sites in the European Alps.
10 The climate models are able to reproduce past climate only if GHG effects are included.
