'After all, two major extinctions have happened before, in the past thousand million years or so".' This is the sort of fantasy and myth that some 'scientist' make their predictions on.

If I have an opinion about a distasteful comment I will continue to feel free to speak as I please. I did not request, nor do I require your approval.
If you want to be treated with respect, then set an example. Using inflammatory and insulting remarks such as blind, sheep, bleating and bullies just because someone disagrees with you is hardly respectful and attracts the response it deserves.
If my opinion of your remarks upsets you so much, as they clearly have done, then don't read it.

Thanks for the input Keiran, that one is an oldie but a goodie. However it has been debunked before. For some concise science about it you can look here.

Curmudgeon:

“The problem is trying to work out whether humans have had any effect on climate.”

How much do you really understand about ‘radiative forcing’?

How much do you really understand about Carbon and Oxygen isotope studies in climate science?

Are you aware that climate change is NOT just about “industrial gases”?

Are you aware that climate science does NOT “rest on comparisons of computer models”? A point that has been made time and time again.

Are you aware that if you take out CO2e as a major driver of this ‘current climate-change’ that NO other natural forcing can explain the warming we have been experiencing?

Yes, the system is complex – let the scientists do their job (climate sensitivity, attribution/commitment and ocean/atmosphere/land couplings will be exciting and challenging). Ergo, people should not misrepresent or distort something they do not understand.

Malrob:

“Q&A and all the other climate alarmists.”

What bit don’t you understand?

Let me rephrase …
‘Denialists’ AND ‘alarmists’ should pull their collective heads out of their butts.

“You don't seem to have looked very far to find some real science which will make you think a little more openly about AGW.”

You seem to be new here (another sock-puppet)? At the very least you don’t know me so your claim is fallacious.

I am well aware of various ‘think-tanks’ that have sprouted to confront the “problems” of addressing climate-change issues. The SPPI is no different to other “denialist” sites such as the Heartland Institute, Cato Institute, Tech Central Station, Institute of Public Affairs, Lavoisier Group, etc, etc.

Indeed, Bob Carter et al seem to be “scientific advisor” trolls.

Answer me this … Why doesn’t Carter (a real scientist) publish his ‘claims’ in reputable journals rather than in blog-spots, newspapers, shock-jock right-wing radio/TV programmes and popular magazines?

David

I take your point about the Pope.

My point … the real problem facing humanity is to do with (un)sustainable development (AGW is just a symptom). As usual, science is developing faster than the politicians, economists, social anthropologists, religious groups, etc. can deal with.

But, who will save the children.

Pffft.

You're quite right, Mark, this article won't make a lot of difference. Scientific opinion is waaay ahead of you. The concensus you deride has been developing since the 80's.

Curious how your article and a similar once recently ignore what's going on in Europe and at the poles. Maybe all these reports are bogus and economists do have all the answers?

Here is yet more evidence of a warming Earth, with measurements showing that the Southern Ocean is becoming less salty, suggesting Antarctic melting.
