I went to Don Aiken's siteand looked at the comments.
The first one stopped me, something I have never seen previously;

My problems start with how to define the temperature of the planet.
I can’t see any credible or meaningful way to do this. Certainly not
in terms of degrees, let alone tenths of degrees.
But if a definition could be agreed, how can actual, meaningful
measurements be made, and melded in some sensible manner?
How could you even measure the temperature of Canberra?
Using the max or min or simple (meaningless) average? Ground level or
some other height? Over grass, concrete? Near buildings?
So for me, any other assertions re global warming are meaningless,
especially when extrapolation for 80 years or more are made

As I said, I have never seen that point made previously.
So can someone who is betting all our welfare on global warming
please explain to me just how it is done ?

Dear Alison Jane,

You on the turps again?

You seem to be equating the quite modest scientist's salary compared to what the fossil fuel giants spend on disinformation.

Why do you think that is? I will tell you, you are a patsy, another one who does the dirty work for them for absolutely zero pay. You go willingly into these forums to spread their crap while they sit there counting their billions and laughing at you.

Well as long as it gives you an inflated sense of your worth I suppose there is something of benefit to you.

Enjoy.

Dear Bazz,

Really?

All Mike Dimm and yourself had to do was go and google the bloody thing.

Try this site and get back to me with any questions.

SteeleRedux,

You are wasting your breath.

AGW / climate deniers do not want to know how the scientific community comes to their conclusions.

They need to see it before they will believe it because they are incapable of critical thought plus they will also be motivated by the fact that they are usually religious, are politically conservative, are dependent on the fossil fuel industry, etc.

Swamp donkey,

Considering that you don't have a clue about the science of climate change it is wildly hypocritical to claim the same about others.

Anyone that has an inkling of physics and chemistry would understand that there are many factors involved in controlling the atmospheric temperature including:

CO2 absorption by the oceans.
Heat reflection by the clouds, land and ice.
Heat reflection due to atmospheric SO2 and other gases

etc

The combination of all these effects caused the original estimates to be so wide (highest estimate was near 10x the lowest) that the claim that the temperature change is within estimates is pretty much an oxymoron.

The climate activists have essentially shot themselves in the foot by taking the worst-case scenarios as gospel and then being surprised when they aren't taken seriously

shadowminister, your talking to an audience of troll here who boast about their intellect and supreme understanding handed down to them by the Great Computer " Deep Throat" ( see Hitchhikers Guide to Universe)and its GCMs.

They are "Klimate Khange Kultists", what else can you expect. Glad to see a fellow who understands enough real science, to understand how little we know, and how complex the real ( not modelled) world is.
