Dear mhaze,

So your categorical statement that:

“they definitely weren't exporting food”.

Has now been reduced to people need: “understanding all the issues of the time and understanding the perspective of the people in that day”.

So no admission you got it abjectly wrong, or misspoke.

Well that really is typical.

And then you have gone and turned yourself in circles.

On Bill and Ben stating the greenhouse effect is a myth they: “say things you don't want to be true and therefore they must be wrong. You don't know how they're wrong so just assert they are wrong based on what others have told you.” ... “They might be wrong and time will tell.”

Then in the next paragraph you basically call them out yourself: “Yes the greenhouse effect is real. Its been real for millions of years.”

Finally you opine: “The issue however is whether CO2 alone causes an ENHANCED greenhouse effect.”

But it isn't for Bill and Ben is it. They are most adamant that it is a myth. Why then are you giving them any credibility when they can't get past even this basic bit of acknowledged science?

Dear Bazz,

You claim: “CO2 does cause warming and the human co2 since the start of the industrial revolution has caused a 0.1 deg C rise to date.”

Do you just make these things up as you go? No, it has risen about 10 times that.

This is direct from the IPCC report:

“Human-induced warming reached approximately 1°C (likely between 0.8°C and 1.2°C) above pre-industrial levels in 2017, increasing at 0.2°C (likely between 0.1°C and 0.3°C) per decade (high confidence).”

Please stop writing nonsense.

Standard SR. Parsing ever word to try and find some ambiguity to exploit.

So let me clarify. The small exports of food from India was dwarfed by the imports. There was no net export of food. There was massive net import of food.

As to the climate issue where you continue to demonstrate a lack of understanding...yes I think there is a small contribution by CO2 to the small increases in temperatures seen in the past 150 years and the paper that so vexes you argues that there is no contribution. But unlike you I'm open to being convinced that my views are wrong and that indeed increases in CO2 make no contribution to temperatures . So we'll see how their thesis stands up to scrutiny and experimentation over the next few years.

That's how science works. The idea that increased CO2 levels are a major contribution to global warming is a theory that is being tested. People like SR think its settled science or more like a religion and that any deviation from that belief is heresy to be shouted down.

That might just make some sense if the SR's of the world actually understood the science. But alas....

In the years around the Bengali Famine, Australia exported some 4million tons of wheat but only sent 1 million to India.

So obviously Curtin is personally responsible for every one of the deaths in India.

What's that you say? There was a war on. Well I don't really think that makes any difference. Curtin should have just pretended there was no war and sent all the food India needed.

From the IPCC report, indeed.
Well maybe they are right, but some scientists are saying they got it wrong.
No one that is pushing AGW wants to even consider it.
The big worry is that this is the eighth known warming cycle and
the present one is right on time +- a couple 100 years.
Still in 50 years time it will be obvious who is right but I won't be
here to say I told you so !

Mhaze said:Noting that we are unlikely to even get to a doubling of CO2, 1.3c increases are entirely manageable and not even close to catastrophic.

That is another point I don't get, 1.3 is not much at all.
Not even a hot day !
Climer says historically it would be great news !
I suspect, must look for this, the normal cycle range would be more
than 1.3 deg. Certainly looks like that range from Maunder Minimum
to today.

mhaze, stop lying, no Australian wheat was exported to Bengal as you claim. YOU MADE IT UP to suit your far right racists agenda.
