The permutations easily exceeds N=2. While there are no doubt ideological biases at work, I have heard dialog from both sides (for the most part) expressing a desire to know the underlying details of the physical processes at work. Endless graphs of time series data do nothing to advance the argument. The only way we understand processes in nature is by observation, hypothesis, and test. In my opinion, scientists should not be subjected to a political process that reduces them and their work to a type of directed technocracy.Wow. I was following this thread a few days ago when it was at about 14 pages of replies. Now it’s up to 21. I haven’t read every post, but I think this debate largely confirms something I’ve noticed for a while now.
This entire debate about the science is just a proxy war. The real underlying fight is between conflicting policy ideas. And that is true for both sides of the debate. People who want to see major government intervention to reduce CO2 emissions think that if they could just educate people about the science, they would support government action. At the same time, those who don’t want the government to curtail CO2 emissions strive mightily to refute their opponents’ scientific arguments.
Why has the science become the battle ground? Why not argue about the proposed policies and leave the science in peace? The only answer I can come up with is that both sides implicitly accept this premise: If anthropogenic global warming (AGW) is real, we must act to stop it. So the people who want to stop it spend their time trying to convince everyone that AGW is real. And the people who don’t want the government to get involved spend their time arguing that AGW is not real (or that it’s not certain).
I don’t think that underlying premise is true. The fact is, policy decisions ought to be based on more than just climate science. Even if AGW is real, it may be costlier to try to stop it than to adapt to it (at least in the short term). That’s a very legitimate economic consideration. So the policy debate is much broader and encompasses more disciplines. Fighting over minute details of climate science will not resolve the policy debate.
You’re definitely right. The situation isn’t as clear-cut and simple as I described, but in debates I’ve observed, the continuing argument seems to be driven onward by the basic opposing viewpoints I described. I’ve discussed climate science with a variety of people, and it frustrates me when I perceive (quite often) that a person is completely unwilling to consider scientific evidence. To me, that strongly indicates an underlying ideological bias. I think it’s unfortunate and quite frankly annoying that scientific questions have become an ideological battleground. The science should inform the policy debate. It shouldn’t become a proxy battleground for policy fights.The permutations easily exceeds N=2.

Ah, yes the gool old times when the Catholic Church realized the practical necessity of population controlThe population of Europe went from about 30 million to nearly 90 million just before the Black plague. The towns and cities were teeming with poor people, so much so that some scholars think the ‘Children’s Crusade’ was merely an effort to get rid of excess population.
Fine, build me a thorium power reactor in your garage. The design is out there since 1950s.But not all innovation and invention require expensive hardware and personnel.
Short term being the operative word here. Because the climatic response to CO2 forcing is delayed, the adaptiation will actually have to be done by your grandchildren. Yes, short term, you are getting all the profit from burning carbon, and long term your grandchildren are getting all the cost. Wonderful deal, isn’t it?Even if AGW is real, it may be costlier to try to stop it than to adapt to it (at least in the short term).
Sorry I missed your post. I have a day & night job.Can you explain or counter the point made in the following video that CO2 levels from ice core data frequently rise after increases in temperature and decline after decreases in temperature, so that a causal relationship between C02 levels and temperature change is not clearly demonstrated?

Added to the point of the video is that both CO2 levels and temperature are constantly in a correlated flux, but not inexorably rising or falling.
You are right that plants absorb CO2, and right now in our temperate zones both the longer summers and CO2 fertilization are causing more plant growth (and better crop yields), taking up CO2. However, when the warming rises to a higher level, which they project by mid-century, they are projecting a sharp decrease in plant and crop productivity. Too much warming is actually bad for plants. At that point and given the methane shotgun release becoming much greater (it is already starting), the warming will likely start going into climate hysteresis, a great warming period that could last up to 100,000 years, killing off both plant and animal life on earth, a great extinction event.Clearly, when temperatures rise AND more CO2 is available, that would inevitably lead to plant flourishing and the fixing of more CO2 into carbohydrates, thereby depleting the amount of CO2 in the air.
Another thing I learned from someone who lives up in the arctic area of Canada is that the soil is way too poor for agriculture.…Assume that the climate warms by 5C, which is roughly 10F. The climate in Texas is now like in today’s Death Valley (a.k.a. desert, so no more ranching). Climate in the US bread basket around the Kansas City is now like today’s southern states, so Kansas City becomes a major hub of cotton production. Wheat production has to be moved to Canada… oh wat, it can’t, because the Canadian land has been irreleversibly polluted by strip mining for tar sands.
This is ridiculous, at least the claim that those concerned about AGW expect major gov interventions will somehow magically reduce CO2 emissions.This entire debate about the science is just a proxy war. The real underlying fight is between conflicting policy ideas. And that is true for both sides of the debate. People who want to see major government intervention to reduce CO2 emissions think that if they could just educate people about the science, they would support government action.

This thread and others like it on this board can easily look like that. The participants who are most passionate are also more vocal. What I try to do is parse out the non-repeating arguments to reveal more points of view. I am fortunate that I have a lot of contacts in the science and technical community, a lot of which are of the pro AGW persuasion and in a climate science field (large lab east of San Francisco) , but not all. We manage to agree to disagree in most cases, and in all cases we admit that there is a huge amount of uncertainty still swirling around the attribution discussion. It is only in these public forums that I encounter the strange phenomena of “uncontested certainty.”You’re definitely right. The situation isn’t as clear-cut and simple as I described, but in debates I’ve observed, the continuing argument seems to be driven onward by the basic opposing viewpoints I described.

One has to go a long way north even in Canada to reach the Arctic Circle. Given that Canada is one of the largest agricultural producers and exporters in the world it is not immediately obvious how a modest warming of her climate could do anything other than lengthen her growing seasons and allow for even greater production. A reasonable (sounding) argument could be made that the Sahara region would become less productive if global temperatures increased, but no reasonable argument can be made that Canada (and Russia) wouldn’t benefit.Another thing I learned from someone who lives up in the arctic area of Canada is that the soil is way too poor for agriculture.
Carbon is renewable; that is just hype to say it is not. We already have engineered bacteria that can convert biomass into oil.So – what will happen when carbon runs out before a suitable alternative method of energy generation is found?
Within 10 years almost everyone will have their own nano-nuclear reactor in their own homes.Fine, build me a thorium power reactor in your garage. The design is out there since 1950s.
And the reason it is more expensive is that we use fossil carbon to make biomass.Carbon is renewable; that is just hype to say it is not. We already have engineered bacteria that can convert biomass into oil.
It’s just more expensive.
I would want to be that optimistic. Particularly given the amount of bureaucratic red tape the developers have to put up with.Within 10 years almost everyone will have their own nano-nuclear reactor in their own homes.
I know a few Canadian farmers that would disagree.Another thing I learned from someone who lives up in the arctic area of Canada is that the soil is way too poor for agriculture.
This is a LIE.That’s easy. Global average temps (GAT) would have to go back down to what they were prior to 1970 and stay there for over 30 years. No problem there. I think that’s actually what the skeptics had predicted and they are WAY WRONG compared to climate scientists, who slightly overestimated what the GAT would be in 2013.
Hansen committed scientific fraud with his data manipulation.BTW, in his 1981 projection Hansen actually underestimated what GAT would be in 2000. Eyeball the mid-point of his projection on pg 4 (about .6 C) of pubs.giss.nasa.gov/docs/1981/1981_Hansen_etal_1.pdf.
On the bright side, it’s encouraging to see you use the term ‘false negative’ which by definition acknowledges the models are in error. A false negative indicates the test or predictive model has failed the scientific method and must be revised to include new and correct feedback mechanisms.We people concerned about life on earth, OTOH, should be striving to avoid the false negative of failing to address true, serious life-threatening problems like AGW. You’d think.
My friend lives up in Nunavut Territory – the tundra area on the map above – I think on Ellesmere Island or some place close to that (I’ve lost contact with him). I believe what he said about the arctic area in which he lives, but he could be wrong, I suppose.I know a few Canadian farmers that would disagree.
But then, they likely live hundreds of miles away from whoever your witness is.
Which I guess would speak poorly for your contention that Canada has poor soil for farming.
Canada is a big place. Sweeping assessments such as yours say more about the person then they do Canada.
