One link Jcarlton gave saying how tiny the size of the Carbon molecule was and how it was "physically impossible" a trace gas could affect climate really made me angry. Because doubling CO2 would cause an increase of 1 degree
There is yet long way to actually doubling CO2. To quadrupling, it might take centuries.
We can agree that the issue should be investigated. But costly cutting CO2 emissions now might be doing wrong thing for wrong reason.
What if we are headed into next little ace age and higher CO2 concentrations are vital for sustaining crops to feed those 8 billions of people?
Scary scenarios are mostly about rising sea levels. Which might be sort of annoyance, but in reality no real problem. Most buildings have limited lifespan and get demolished in 50-100 years anyway. Just do not build them in the same place...
I believe there are chances that stopping CO2 emissions might be exactly the WORST thing to do. It is as reasonable to predict this as to predict otherwise.
energy we may well double or even treble the CO2 content in the
Quadruple?
atmosphere over the next 150 and amplification factor of 3 is inside the realms of possibility.
OK, so we will have 6 more degrees. Fine with me.
Frankly, I guess most people so far just enjoy warmer climate, except there are less opportunities for skiing
That it is safe to emit CO2 is not some trivial thing that any school child would know the answer to... its a serious question that needs serious investigation (which it seems the IPCC aren't doing) and we don't know what the results will be.
Come on. Every school child knows that emitting CO2 the crime against humanity. Or that is what they are taught...
That we should replace fossil fuels with nuclear and renewables as a precautionary meassure seems very prudent even though there is uncertainty of the risk. What's more it will prepare us for the oil peak so it will be doubly good.
We could have done that long time ago, except that the same people that are now crying about CO2 prevented it.
Nuclear definitely makes sense.
And for the record, I am really looking forward to my first electric car (generally, not that I plan to buy some now, but I am quite sure that in 5 years, I will have some) - not because I worry about climate, but because I like the concept and I think electric cars will be more comfortable.
Note: Even if the oil peak isn't immediate but decades away its still worth beginning the transition because installing generation capacity takes energy so the best time to do it is at a time of rising production, since if you do it when production is falling, you'll exacerbate the problem still further by removing even more energy from the economy.
I can agree. These are all legitimate reasons to develop non-fossil dependant sources.
But "CO2 science does not matter" is quite different from "CO2 science is settled".
As to the attitude that we don't know the optimum and that things might improve with climate change... unless you're miles away from the optimum all change is bad this is because lifeforms adapt optimally to their environment so any change in that environment tends to push them away from that optimum.
Uh, I would rather expect that for 6 degrees rise, there would be some migration in the first place. Actually, we live through the process right now - e.g. in central europe, some species that were not present 30 years ago are now normal. Of course, this is presented as negative effect of CO2 emissions by greens, but in fact, it is adaptation in progress.
Just for the record, if there are one species extremely skilled at adapation, it is human race...
