And standby for another really aggravated argument.
Two groups of scientists have confirmed what Abbot & Marohasy reported
in 2017 that global warming is a natural event cycle.
These new studies from Finland and Japan have gone further and state
that they believe it is caused by sunspots and cosmic rays on cloud formation.
The other result is that CO2 has almost no significance.

Now this all very new info and it will have to be confirmed and repeated by others.
But watch it hit the fan when it does surface.
Imagine the argument in the Liberal Party on that !
There won't be an argument in the Labour Party, the Greens won't allow it.

you are acting as if facts really matter in the debate Bazz. Surely by now the mulitudes of facts have exposed the lying fraudulent gw scam. It makes no difference to regressives. They simply move on to their next group of lies. Look at the whole Russian collusion conspiracy that the lying Liberal media banged on about for years. No apology, no acknowledgement of lies and yet nothing to see. Facts do not matter in marxist ideology. Simple as that and as soon as conservatives stop playing idiotic games with the UN the better.

"Now this all very new info "

Bazz,

Actually, the hypothesis isn't new. It was proposed at least 2 decades ago by Svensmark and has been studied ever since. This information you refer to is additional data in favour of the hypothesis.

The idea has been completely rejected by the IPCC (big surprise eh!) but my impression is that more and more scientists are coming around to the idea and consider it at least part of the solution toward explaining changes in global temperatures in both directions.

While on the issue, 90 Italian scientists have sent a petition to their government urging it to adopt a more realistic policy toward climate change and pollution. Part of the petition reads..."the anthropogenic origin of global warming IS AN UNPROVEN HYPOTHESIS, deduced only from some climate models, that is complex computer programs, called General Circulation Models . On the contrary, the scientific literature has increasingly highlighted the existence of a natural climatic variability that the models are not able to reproduce."

Craig Kelly is all over the issue (the above is his translation). I wonder if he's part of that 'broad church' some want?

Runner & Mhaze,
yes I agree the argument will be difficult to press.
I was not aware that it is a quite old theory.
The part I found interesting was about the digging it out of the noise
of proxy temperature measurements by using techniques used in radio astronomy.
A friend of mine who at CSIRO was involved in inventing wifi use of
that technique would have been thrilled about that if he had not died last year.
I think that the whole idea will be hard to deny at the IPCC level
when it get taken seriously. The application of well proven
mathematical techniques will peel off a lot of the opposition.
All this of course will need further confirmation & repeating.

The real problem will be that so much money and academic and political
prestige has been invested into the current mindset that the Pope's
condemnation of Galileo will seem like a polite tea party discussion.

So what has happened to change that?
Foxy,
As I said changed Demographic.

Labor has gone from helping the working class to totally exploiting it !
