I assume it's the democracy bit that is your core premise. I'm not certain which country you live in. If you're in the U.S., you're not living in a democracy, you're living in a republic. There is a strong agenda by many people to turn it into a democracy, merely by saying it is one, and that is working, but by law, it's a republic. Democracies tend to disintegrate rapidly as the populace votes themselves beer and ci…

What is the specialty of the Republic? I guess there are laws that the zombie masses have to adhere to, but these laws were once upon a time also created by people. I don't want to defend democracy, but it seems that it is not trivial to come up with a better system, and "don't give non-experts the permission to speak" won't cut it in my opinion. As soon as you start going down that road, a lot of other issues crop u…

A better model: Perhaps smaller democracies? Instead of everyone having 1/300,000,000-say in 300,000,000 lives, let them have bigger chunk in smaller systems.

Stronger, faster and more direct feedback can enhance control loops without adding more sophistication otherwise.

Still, the writing is horrible.

Having gone to the article hoping for details on why Dyson disbelieves global warming, I'm disappointed like you. On reflection, I think the author intended the article to be about Dyson himself, and as such, I kind of like the writing. But, yeah, I'm disappointed about the lack of details.

The title of the article here is misleading. He isn't the global warming heretic, he's always been a heretic in everything that he's done or talked about. The simple fact is he's quite often accurate.

"There are very few if any people who believe that it is impossible that global warming is not caused by man." Are you saying that nobody claims that the observed global warming could not be caused by natural causes, and thus the warming must have been caused by man? For if you are claiming this, I think you are wrong. There are definitely a few very influential people claiming that climate change can only have been…

You're reading me correctly. My claims are basically that: A) I think that very few people actually believe that global warming could only be caused by anthropogenic forces. B) I've never actually heard anyone claim that global warming could only be caused by anthropogenic forces, so if people are even saying that then they are in a small minority. (The difference between A and B is that there may be people who say g…

As the quote by Mann is from a published scientific paper rather than an editorial page, I can only hope that the statement is believed by the authors. I disagree that it would be reasonable to make an unsupported political statement in this context, thus I assume belief.

The IPCC AR4 statement on this matter (presumably written or at least approved by Mann) has this to say: "The observed widespread warming of the atmosphere and ocean, together with ice mass loss, support the conclusion that it is extremely unlikely that global climate change of the past 50 years can be explained without external forcing and very likely that it is not due to known natural causes alone." p.39, http://www.ipcc.ch/pdf/assessment-report/ar4/syr/ar4_syr.pdf

While there is an important difference between 'impossible' and 'extremely unlikely', I think a journalist or lay reader could reasonably conclude that the scientific consensus (as represented by the IPCC report) is that warming could only be caused by anthropegenic forces.

I find it interesting that the planet is presumed to be warming at roughly 0.02C a year, yet we pump out [enough energy to raise the temperature by 20C a year]. (Ed: Sorry, I'd mistaken my numbers. Our potential to raise the temperature of the atmosphere is actually 200 times what I'd mistakenly put (originally 0.1C). Our potential to raise the temperature of the oceans is 0.1C a year, when in fact the oceans temperature raises at 0.01C. Sorry for the mistake folks!)

I have several problems with all the eco-energy projects. Namely wind turbines are likely to cause more ecological problems than solve, I'm sorry but they're killing off bats in phenomenal numbers and killing a species high up on the food chain causes problems. We do it to seals, but we eat the fish that they would so ecologically it's not all that harmful... unless we're going to start eating millions of tons of bugs a year, I think killing off the bats might cause a serious problem. I mean the last thing we need are plagues of locust.

The other problem with wind turbines is that they slow local wind speeds, if this is produced on a global scale this could inhibit the transfer of energy to the night-side of earth to be radiated away. This is the same problem that wave-energy will produce, mass use of this technology will cause a reduction in water flow, which in turn will cause more energy to be stored by the water. This one is particularly unpredictable: reduced tidal action will reduce the cooling effect of water vaporisation, however this will likely be balanced by an increase in evaporation, yet this could potentially be disastrous because hotter water = stronger storms, so mass use of wave-power technologies could drastically increase tropical storms, more than global warming ever could. Hopefully the wind turbines can slow these down!

I haven't even touch on the fact that wind turbines place angular stress on the ground they sit on, which on a large scale has never been predicted. I mean we're talking about placing angular forces on entire tectonic plates that will change as the direction of the wind. The effect of this is inherently unknown, and I don't want to know what could happen at stressed fault-lines.

My problem with solar power is that it reduces the albedo of the planet and ultimately turns the electrical energy into thermal (infrared) energy, which is then trapped by CO2! Lowering the planets albedo will increase global warming even if we decrease the amount of CO2 in the atmosphere, this problem will be compounded if they ever get the holy grail of solar energy, the orbital solar power plant. Placing solar power plants into space won't increase the planets albedo, however it will transfer ridiculous amounts of energy to the planet and to be viable they only need a 20-30% efficiency due to the sheer abundance of energy. However, the other 70-80% will still be absorbed by the atmosphere and convert to thermal energy. (If anyone doubts this, please put a cup of water in the microwave and this is essentially the result as 70-80% of the energy will be absorbed by the atmosphere, which is roughly equivalent to a 10 meter layer of distilled water)

Global Warming is (95% probable) a byproduct of human civilization in one way or another. However the solution proposed by environmentalists is a planet wide geo-forming project.

I think the potential for harm could be much, much greater from geo-forming the entire planet than sea levels rising. We know what global warming could do to the planet, we don't know what geo-forming could do to the planet and no one is looking at it.

Sometimes I feel like I'm the only person on the planet that realises the solutions to the problem are potentially worse than the problem itself.

Aren't many lobbyists resembling the "might makes right" practices? From what little I understand so far, there is quite a bit of money involved, and decisions do not always seem to be as honest and altruistic when the amounts get large enough. And aren't the politicians replacing responding to populism and mob voice with the loudest voices nearest them? Especially those that may finance the politicians' agendas? I a…

I agree with you. It seems in this day and age if you wanted to find some information about a topic you cared about you could gather enough information online or by asking some experts. Lobbyists tend to have a biased opinion.

I would love to see some social website experimentation with online voting, and caucusing/solicitation of voters' desires, correctly tracked to one per registered voter.

Might they not already exist?

If we can make one robust enough and popular enough, maybe it can be the model (or the actual tool) used by our wonderful pols...

A friend and I once carried several large pieces of trash out of a wilderness area. We were sore, and tired, and our packs were heavy, and we were eager to go home and shower and eat some junk food. I'm glad we didn't make a rational decision.

You are glad based on how it made you feel, not on what impact it made. Most probably it didn't have much impact and you might as well have dropped the trash. Not that that's what I would've done, but saying we should trust our emotions on this big and costly problem makes no sense. Of course, throwing rationality out of the window by definition doesn't make any sense. I'm not sure what your point is.

I was taking issue with the definition of a "rational" decision in terms of environment as merely a cost-benefit analysis.

I'm, frankly, sick of cost-benefit analysis being applied to everything. It has become the hammer that's turning everything into a nail. It's led to a pretty ugly state of software in a lot of different arenas, because a CBA doesn't support spending much time running down memory leaks, or trying to reduce software footprint.

The problem with using CBA in software -- and more to the point, in the environment -- is that it ignores the cumulative effect of lots of small decisions. Each individual action may not make "rational" sense in terms of CBA, but the consequences quickly add up.

To go back to my specific example, you're right that our hauling out some of the trash probably had very little positive impact on our environment. However, it is the cumulative actions of us and others like us who ensure that our trails stay clean.

For yet another example, if you climb Mount Rainier in Washington, you are expected to pack out all of your waste. I would guess the average trip time to the summit and back to be about three to four days, so that means that parties must carry their poop in their pack.

From an individual cost-benefit point of view, that's ridiculous and not rational. It requires a lot of effort for -- on an individual basis -- little environmental benefit.

However, it's the cumulative impact of thousands of summit parties every year that has a very real, and very detrimental, impact on the mountain's ecology.

Basically, cost-benefit analysis is a stupid, shortsighted way to make decisions.

In business, war, governance, love, and the climate, people are forced to make decisions based on sorely incomplete data because time is of the essence, and it is all they're ever going to get. If likely exaggeration is to be called out, so too are those who assert that doubt should necessarily imply inaction.

Why is "time of the essence"? Who told you so? Al "Save the Polar Bears" Gore? I promise you, those polar bears were in no danger. Do you know what a stampede is? It's a frightening thing, where a large herd of animals is frightened and begin to run. They run and run, trampeling anything in their path, killing anything that gets in front of them, and each other, as they run from the danger on their heals. Never would…

Al Gore has nothing to do with my reasoning process.

These are the risks mentioned in the IPCC Synthesis report. The seem sound and reasonable.

    * The report says that around 20 per cent to 30 per cent of the plant and animal species assessed are likely to be at increased risk of extinction if global average temperatures exceed 1.5 degree C to 2.5 degree C over late 20th century levels.
    * The report also points to the likelihood of "irreversible" impacts. For example if temperature increases exceed about 3.5 degrees C, between 40 per cent and 70 per cent of the species assessed might be at increased risk of extinction.
    * Increases in sea surface temperatures of about one-three degrees C are projected to result in more "frequent coral bleaching events and widespread mortality."
    * There is also concern over the oceans and seas becoming more acidic as they absorb rising levels of carbon dioxide and the impacts on "marine shell-forming organisms" like coral reefs.
    * Other reasons for concern focus on the risks of extreme weather events with higher confidence in the projected increases in droughts, heatwaves and floods as well as their adverse impacts.
    * The report also flags up concern that the poor and the elderly in low-latitude and less-developed areas including those in dry areas and living on mega-deltas are likely to suffer most.
    * There is high confidence that by mid-century "many semi-arid areas, for example the Mediterranean basin, western United States, southern Africa and northeast Brazil, will suffer a decrease in water resources due to climate change."
    * The IPCC summary also expresses concern that any benefits linked with climate change will be gone after more modest temperature rises. The guide, launched after five days of discussions in the Spanish city of Valencia, will be essential reading for delegates attending the upcoming UN climate convention meeting in Bali, Indonesia.
    * Concern is also raised that new observations linked with the Greenland and possibly Antarctic ice sheets may mean that the rate of ice loss will increase above previous forecasts.

You are suggesting that we ought to take all costs into account when doing cost-benefit analysis. You are not providing a substantive criticism of cost-benefit analysis.

Rational decision making always involves assessing the (probable) costs and benefits of potential actions. If the potential benefit is small and uncertain, and the cost is large and certain, it probably makes sense to wait and collect more information. http://en.wikipedia.org/wiki/Opportunity_cost http://www.ted.com/index.php/talks/bjorn_lomborg_sets_global... http://www.copenhagenconsensus.com/CCC%20Home%20Page.aspx

Lomborg's claims rest on the assumption that the benefits are small and uncertain. I remember him citing "heat deaths" as one of the worst predicted outcomes of global warming. "Warmists" would certainly disagree that this is the worst thing to expect. I don't know the proper name for this argumentation technique, in my opinion Lomborg creates a kind of strawman, but that is not quite the right word. He says "look he…

While Lomborg's five-minute speeches do not touch on every cost and benefit of Global Warming, the Copenhagen Consensus does operate with the latest research estimates of the comprehensive costs and benefits.

If you're looking for an easy way to dismiss Lomborg, you're not going to find one. The dude is not a hack.

If I had wanted to suggest that, I would have.

How does a group of people take all costs into account when doing a cost-benefit analysis if they can't agree on what constitutes a cost and what constitutes a benefit, and their relative values?

You and others here are talking about CBA as the basis for rational decision making, and yet I bet you couldn't even describe it in any formal way that could apply to all logical decisions.

What does it mean to do a CBA in terms of your immediate environment? What factors are you taking into consideration? Aesthetics? Health? How much money is clean water worth to you? Or, from a CBA standpoint: is it worth pouring a gallon of paint into your drinking water, or is it better to transport that paint to a remote facility which will handle it in some fashion? And in that one relatively minor decision alone, how many different factors are you going to account for? The size of your drinking water supply, the chemical composition of the paint, the ecology of your drinking water supply, the distance to the waste managing facility, the vehicle used to get it there, the methods the facility uses to handle it ...

This CBA hand-waving is bullshit. It's impossible to take all costs into account for this kind of stuff. Most people -- even the most knowledgeable climate scientists -- don't even know what all the costs are. So just how are we supposed to justify our environmental decisions using a CBA when you can't even correctly do the accounting in the costs column?

And this is what constitutes the basis for rational decision making? Bah! Bah, I say!

I think it's perfectly rational to make decisions based on morals and ethics, and whether or not the consequences of that decision get you closer to your goals or not. So, for example, one of my goals is to experience wilderness areas in as pristine a state as possible. I see trash there. The trash is heavy, and I have a long distance to hike out. It will cost me a great deal of effort to remove it. But, it still does help to accomplish my goal: the next time I visit that place, the trash won't be there (nor will it be there for the next visitor). Thus, I will remove it, if possible.

Is that not a rational decision-making process? Does that not make sense from an environmental standpoint, as a species?
