What is also amazing is that all it does is contribute a small addition to a trace gas in the atmosphere, that is necessary for photosynthesis in plant which sustains life on earth,
yikes indeed.
"all it does"yikes indeed.
What makes you think "a small addition to a trace gas in the atmosphere" wouldn't have a big effect? You don't accept the greenhouse effect exists?
Edit to add sorry for the delay getting back to you but I was busy planting out cactus but the snow was making it difficult.

This comparison to an imaginary event does not actually tell me anything useful about mankind's impact on the planet, at all - What am I missing?
If there were a fire significantly larger than the continent of Africa, do you think people would be likely to conclude that it was having no effect on the planet's atmosphere?Man's CO2 emissions exist, but they are not a fire the size of Africa
This article is only saying that if we were to emit this amount of CO2 by burning forests instead of fossil fuel, it would need to be a big fire (duh!)
This particular article tells me nothing about what effect man's contribution to atmospheric CO2 is actually having
This is therefore just a scare tactic

You're still missing the point. It's a metaphor. Man's CO2 emissions exist, but they are not a fire the size of Africa

Some people can justify denying AGW to themselves because they can't put the effects of burning fossil fuels in a context they understand.

There is no certainties in climate change, the whole thing is full of maybe probably and other such vague wording, they are so unsure of what is happening that it has to be kept vague
Good grief, you've sunk to the robinessex level of argument!There are no certainties in any field of science. That's how it works.

Reality has a 'scary' bias sometimes - we shield children from them but we're supposedly adults here.
There is no place in science for scary bias or metaphor - Publishing this imprecise comparison is tabloid-worthy dramatising and exaggerating for rhetorical effect - So politics at best, at worst just propaganda, which is highly frustrating, when what we need is scientific fact.especially from an outfit that calls themselves 'Scientific' American

my understanding is that CO2 effects are swamped by H2O effects that are readily seen.

The CO2 level in itself does not warm the climate it is the effect of trapping the radiated IR and re emitting it that does.
We can do nothing about volcanic activity but can do everything about our activity. Given the will we can produce all the energy we need from none fossil fuel sources. We have the ability now to do it but we lack the will in part due to nay sayers always looking to be right against all the evidence whilst producing no evidence of their own - just splitting hairs.

The scientific facts are available for anyone to view (including on Scientific American), and have been for years. There are millions of scientific facts about AGW available on Google Scholar. especially from an outfit that calls themselves 'Scientific' American
The science and data has been shared and shown and presented and graphed and explained endlessly, but the existence of these threads is proof that just stating scientific facts is not enough.
Sometimes people need to be shown another way of looking at something before they understand it.

For there to be any fear from the "facts" about CO2 it needs positive feedback from water vapor. This has not been shown/proven and they don't even know the sign of the forcing from clouds...... So again why is so much money being thrown away to a highly probable non-problem?The science and data has been shared and shown and presented and graphed and explained endlessly, but the existence of these threads is proof that just stating scientific facts is not enough.

All you are doing is splitting hairs about what Al Gore said in '97. Science moves on and what were once proven are replaced with more accurate theory and proof (Newton and Einstein) but we get along fine with Newton for most purposes.
Also it isn't you spending the money is it and where do the trillions come into it? A move towards renewables is well under way and could be done quicker if we had the will, did you notice that we didn't use coal for electricity production last week? It is a gradual change which will take decades but it is happening and all the denial in the world hasn't stopped it.

What I believe is you don't have sufficiently competant understanding of the fundamental basis for AGW to have any business holding a contrary view. To hold the view that increases in a trace gas can't have a significant effect it's beholding on you to understand the established science that says it does so you can critique it from an informed position, otherwise it's just worthless uninformed opinion of a layman, easy to ignore. The only thing interesting about your oft repeated homespun 'ideas' is the irrationality of your confidence in them in the face of so much science.
I'm sure the German physicists of Einstein's time could easily ignore the worthless opinion of a patent clerk. Doesn't make them correct.Seriously though plunks - why are you falling for the same old snake-oil -"only the experts" can understand it gumpf?
Heck homeopathy insists trace substances can have mighty effects!
PRTVR said:
Oh sorry didn't realise I was unworthy to have an opinion on the subject, we can't have alternative ideas can we ?
Opinions uninformed by data are fairly worthless. My opinion is that our fossil fuel usage is causing a temperature rise. Backing this up I see an observed rise in CO2 concentrations. Isotope ratios and simple mass calculations tell me this comes from us burning fossil fuels. About a century of theoretical physics backed up by rigorous measurements, both in the lab and directly in the atmosphere, tells me that this rise significantly changes the atmospheric IR absorption. Calculations tell me that this should lead to a rise in surface temperature. The instrumental temperature record tells me that the surface temperature is rising.
Where does your opinion come from?

I don't think he said that 'only experts can understand it' though, did he? What he's saying is that some of the criticisms voiced on this thread show that a lot of posters don't understand enough about the thing they're arguing against to have an opinion that's worth listening to. Seriously though plunks - why are you falling for the same old snake-oil -"only the experts" can understand it gumpf?
