Another possibility I've heard of is putting sulphur very high into the atmosphere; this is what occurs when there's a large volcanic eruption anyway so it's kind-of 'natural'. And it will instantly cool the planet - we know this because its happened with previous large volcanic eruptions as discussed earlier.Why not just fine dirt?
For what it’s worth, 3% of 4ppm is a trivial calculation 120ppb or 0.12ppm.Fund fact, that's roughly his net earnings every minute.
In perspective, if you left Bill Gates with 120ppb of his approximate net worth of $104.3 billion - he would have approximately $12,516.
Most of the protesters are arts students that haven't done a science subject since year 9. It still takes them 7 years to do the gender fluidity course.And how do you happen to know that as a certain fact?

Well I guess volcanic ash is the just extremely fine dust and sulphur anyway - but it does have a profound cooling affect on the global weather and temperatures. As we've discussed before the most recent 'explosive' volcanic eruptions in recorded history were Indonesia's Tambora (1815) and Krakatoa (1883) but there's evidence of much larger ones in ancient geological history: A large eruption in a system of caldera based at the Yellowstone National Park area about 620,000 years ago that ejected 1,000 cubic km of ash. To put that into context, Tambora was 50 cubic km and Krakatoa was 18 which makes those modern ones seem relatively tame by comparison - and there's evidence of even larger explosive events in North and South America that are up to eight times bigger.Another possibility I've heard of is putting sulphur very high into the atmosphere; this is what occurs when there's a large volcanic eruption anyway so it's kind-of 'natural'.

of course the increase level of cloud from higher water evaporation may also do the same.
1000's outside the office buildings in the Melbourne CBD today protesting and blocking traffic. it is on a roll this climate action stuff.Your taxes are funding these oxygen theives
Volcanic ash is also a health hazard to aircraft engines. The classic case was flight BA009 from Kuala Lumpur to Perth in June 1982. The 747 ingested volcanic ash into all its engines and all four engines flamed out at 37,000 feet. The aircraft was down to 13,500 feet before one engine re-started, followed by the others one by one.there is a difference between a dust haze and flying directly into a cloud, anyway we didn't say use volanic dust.
There may be considerable objections from the world's airlines to the idea of firing volcanic ash into the sky.

I have no idea whether this would have unacceptable side affects such as limiting aircraft movements, really adverse environmental impacts etc. The science behind that idea could also get the calculations wrong and accidentally cause another mini-ice age.

there is a difference between a dust haze and flying directly into a cloud, anyway we didn't say use volcanic dust.Actually Don did mention it which is why I chucked in my two bobs worth.(But who cares anyway? It was only an aside).
Is there going to be one of these wastes of time in Adelaide tomorrow? Damn it! And to think, I was almost going to suggest that they had indeed gained some credibility by doing the protest on a weekend - then I realised that Victoria didn’t have a public holiday today...What a 3 day weekend and they still want to protest on a week day?
Again, PRECISELY ZERO credibility in Adelaide - three whole days of weekend and they instead choose to do it on a work day instead.
I suppose we could use the fly ash from the coal fired power stations, kills two birdsthere is a difference between a dust haze and flying directly into a cloud, anyway we didn't say use volcanic dust.Actually Don did mention it which is why I chucked in my two bobs worth.(But who cares anyway?

Not picking on you personally (for once...) but this attitude has been commented on more widely lately.What's going on, if it isn't due to an environmental change which is dictated by climate change or man made activity?The climate IS changing; how much of that is to do with anthropomorphic climate change is going to be almost impossible to separate from climate change that would have occurred naturally anyway.
I suppose we could use the fly ash from the coal fired power stations, kills two birdsSulphur being the substance that remains at high level stratospheric circulation for a while and keeps global temperature down; it's worked before. How do you inject sulphur at extremely high levels like that (without a volcanic eruption) and how do you as a planet agree that this is the correct solution?
Don suggested a report that mentions Sulphur, I can only think they are looking for a home for all the sulphur they remove from oil and Natural Gas.
Now, if you build a large scale PV solar farm, would it reduce the ambient temperature in that location?
The "climate" is extremely erratic and affected by loads of things not necessarily to do with the activity of people. Yes, releasing huge amounts of carbon dioxide is bound to have an affect on the climate but given that the global weather patterns etc are always in a constant state of flux then maybe our impact is over-stated. Certainly the psuedo-science of prediction has so far proven completely useless.Not picking on you personally (for once...) but this attitude has been commented on more widely lately.What's going on, if it isn't due to an environmental change which is dictated by climate change or man made activity?The climate IS changing; how much of that is to do with anthropomorphic climate change is going to be almost impossible to separate from climate change that would have occurred naturally anyway.
It has recently been suggested that in the past, deniers were deniers full stop. Now, it is common for them to acknowledge that climate change is actually happening, but the cause is denied.
At least you're on the right path.
Why are the Admin locking the "climate change" threads?Because they are Cancerous to read and people need time to chill off with the personal attacks. These Get very heated and personal.
As long as you are man enough to admit that being a pundit has similar shortcomings.
Given that the forecasting is always - ALWAYS - wrong
