The problem is, you consider Co2 to be the cause of climate change.....
I however consider Co2 to be an effect of climate change, and the scientific evidence is sufficently ambiguous to support both beliefs...
No. I consider there to be an equilibium between temperature and atmospheric greenhouse gases. When you add something to one side of the equation, the system changes.
You are simplifying what I say to the point of not making any sense.
So you don't think that Co2 is causing climate warming???
So you don't think that CO2 contributes to the Greenhouse Effect? Without CO2, you'd be frozen solid. Add more CO2 and it will get (on average) warmer, but it's not a simple cause and effect relationship. You can't have it both ways, either it's a greenhouse gas or it isn't.
What you're saying amounts to saying that you can fill a glass with water only to a certain level, and that if you keep adding water beyond that, the level will remain constant.
Let me check if I understand you correctly?
Yes Co2 is a greenhouse gas, as is water vapour, methane and ozone...
But so what?? Human contribution of Co2 to the atmosphere is pretty negligible really.....
Ok, on the assumption that climate change is natural, it must have an upper limit to the 'warming' part of the cycle, yes?..
So if humans add to the greenhouse gases (by emitting Co2), is that a 'major' problem?...if we (hypothetically) add 0.002% to the GHG mix, this might increase the temperature by 0.002% while the temperatures are on the 'up swing' cycle...
However, when the natural warming cycle ends, and the cooling starts, that 0.002% means the cooling cycle might be slower and not reach as low a temperature as normal....
In truth, SO WHAT????.......Instead of the world temperatures peaking at 16 Celsius, they'll peak a 16.002 Celsius....not exactly a major difference is it???
Temperatures go up, and temperatures go down, and have for as long as the Earth has existed.....And there's really nothing we can do about it, except adapt ....
Someone in this thread (I think it was Ernie) responded to a comment of mine that CC was natural with a line like "So when the sea levels rise 6m that's ok cause it's natural".....
Well no, a 6m sea level rise might be a problem, given how close to the coast lines we tend to live.......but it's not going to be 'catastrophic' unless it happens in ridiculously short time ( a day, a week, a month, a year etc)...
In all truth, we have as much chance of stopping climate change as we do of stopping winter, or sunset....we might have to change our living styles a bit, to cope with it....but humans, as a species, have done that lots of times before...
