Climate scientists agree: Humans cause global warming

James Smith 3

Re: Young Turks

"Any young turk out there will catch the cherry-picking and rush to publish a paper pointing out the cherry-picking, thereby discrediting the first scientist and enhancing his own reputation for scientific acuity."

Well that's fine in theory, but in practice no young turk will be going anywhere near attempting to discredit other scientists, especially when those scientists are leaders in their field and their friends have a say in whether said young turk has a future career in science.

This problem is documented in Lee Somlin's book "The Trouble With Physics" where he discusses how it's very difficult to get a career in theoretical physics unless you sign up to string theory. Any young scientist attempting to confront the orthodoxy is likely not to have a future in physics. I fear that climate science has gone the same way.

Re: @ James Smith 3

However, the real world involves burning the fuel in a power plant, and gas fired power plants have been shown to produce half of the CO2 of their coal fired counterparts.

http://www.global-greenhouse-warming.com/gas-vs-coal.html

"The CO2 emissions from Natural Gas Combined Cycle (NGCC) plants are reduced relative to those produced by burning coal given the same power output because of the higher heat content of natural gas, the lower carbon intensity of gas relative to coal, and the higher overall efficiency of the NGCC plant relative to a coal-fired plant.(1)"

“The average emissions rates in the United States from natural gas-fired generation are: 1135 lbs/MWh (Mega Watt hours) of carbon dioxide, 0.1 lbs/MWh of sulfur dioxide, and 1.7 lbs/MWh of nitrogen oxides. Compared to the average air emissions from coal-fired generation, natural gas produces half as much carbon dioxide, less than a third as much nitrogen oxides, and one percent as much sulphur oxides at the power plant.(2)"

Re: @NomNomNom

In practice, energy now being generated from coal will be replaced by energy generated from gas, resulting in less CO2 emitted, which has already happened in the US.

Pirate Bay founder arrested in Cambodia

James Smith 3

Re: All in a name.

They should've called the site "Google".... but seriously, if the site was called something like "AllTheTorrentsInTheWorld" then it's possible to claim that they were just indexing torrents and the fact that there were torrents to copyrighted material wasn't their fault; they just indexed everything after all.

However, with a site called "ThePirateBay" it strongly suggests that the original intent was to set up a site which promoted the smuggling of illicit material, with a old pirate ship for a logo, just to make sure you're not in any doubt as to the purpose of the site.

Mind you, whether or not the judicial system takes that intent into account is another matter....

McIntyre: Climate policy crippled by pointless feel-good gestures

James Smith 3
Thumb Up

Re: Cleaning Out The Augean Stables.

It's perfectly reasonable for the policy makers to follow the advice of the IPCC. When making decisions about something you're not an expert, it makes sense to take the advice of the experts in the field. Without the relevant scientific knowledge the policy makers cannot question the advice of the IPCC, so must take it as truth. In this way the IPCC effectively defines policy with its conclusions. This is dangerous if the report isn't entirely unbiased, as some claim.

You're right that forming another panel isn't the way to go. It would be really obvious political maneuver in an attempt to change the result of the science. Science is supposed to be the driver of policy, not the other way around, but it shouldn't seek to define that policy - that's the job of politics. The real answer is for the current panel to be more transparent and amenable to criticism. There is evidence that what makes up the IPCC report isn't entirely unbiased. They don't appear to mind where the results come from as long as it looks like the right answer and keeps the report "on message". (See GlacierGate for a good example). I think that the attempts by members of the IPCC to define policy rather than just present an honest picture of the science is a great deal of what Climate Audit is all about.

Facepalm

Re: PNAS Review

I'm not denying the consensus. Just your evidence for it.

So I can't suggest a better metric. Doesn't mean the one used in the paper is any good. It doesn't mean their conclusions are sound either.

Imagine two researchers tossing coins. Each time they perform the experiment they write a paper. One researcher always gets "heads", the other always "tails". If there was an editoral bias towards publishing "heads" papers (it sells more journals for instance) then the first researcher would appear to have greater expertise due to having more papers published. Do you see how the bias has obviously affected the link between getting published and expertise?

For the conclusion of the paper to be valid it must prove that the result is not affected by any potential bias. It's an obvious source of error that must be accounted for.

Do you think we can solve the problem of wave-particle duality by looking at how many papers were written about each? Quantity does not equal quality.

Re: PNAS Review

I was just pointing out that your call to authority is based on publication counts and is therefore potentially affected by all sorts of bias. (Funding, peer review, confirmation, editoral... the list is endless) Sure, expertise can be measured by publication count, but only if you assume that there's no bias. There's so much politics involved around climate change, I'm not sure that's true in this case.

In fact, Dr Mouse's post was about sources of bias and your post about the PNAS review does nothing to answer those points. It may even be evidence of the bias he's talking about.

Was the review peer reviewed itself or is it just "grey" literature?

Ice age end was accelerated by CO2

James Smith 3

Re: Dodgy science

I'm not convinced by their explanation of this either. The BBC has a good article with a clearer explanation and some nice graphs to back it up: http://www.bbc.co.uk/news/science-environment-17611404

The sun warms Antarctica and that then causes a CO2 increase which warms the rest of the world. Sounds logical, but wouldn't the CO2 derived warmth then feed back into the Antarctica temperature graph? I can't see evidence of that; the global temperature just looks like a delayed version of the Antarctican one.

They could well be onto something with their theory, but I'm not sure they've got all their ducks in a row yet.

Re: Think of it as insurance...

You don't mind because the amount you pay for your insurance is relatively small. If you had to pay a life changing amount for your home insurance because the insurance company says your house is very likely to get flooded in the near future, you'd be quite annoyed if they turned round ten years later and said "whoops, sorry we got it wrong". You'd be asking for your money back. (with a pitchfork.)

Your second point is an interesting one. I was thinking long the same lines.

Re: Think of it as insurance...

Best case? Well, that depends who you are. If you're someone involved in the decision to move or a scientist/enviromentalist that said that the sea was going to rise, then you might be in a bit of trouble. Everyone isn't going to be breathing a sigh of relief; they'll be round with their pitchforks demanding to know who was responsible for turning their lives upside down for no good reason.

This is the age old "better to do something just in case" argument. What really matters is getting the correct information and making the decision correctly. This is an excellent example of why good science is vital and how alarmism could cause unnecessary pain and suffering.

I'm not saying that the Kiribati people shouldn't relocate in the face of a grave climate threat, but there better actually be a grave climate threat or there will be hell to pay.

Of course you can draw a conclusion. You can conclude that the amount of change is smaller than the accuracy of your equipment. And as that is quite a bit smaller than the previously accepted figure you can also conclude that the accepted figure is wrong.

James Smith 3

Not really. It just means the change is so small that they're having trouble measuring it accurately with the tools they're using, but they do know that the change is small.

Yes, the change could be between +16 and -20, but it's more likely to be in the middle of that range. All depends on what's causing the potential errors.

EFF helps MegaUpload users claw legit stuff back from Feds

A load of people posted things they shouldn't so the church has been cordoned off by the police and the vicar hauled into court as he was making a lot of money by turning a blind eye. Trouble is, the notice board was rented and the owner has come to collect it, threatening to put all the documents in the bin in the process.

It is this kind of argument that makes me not want to take my climate change medicine and instead ask awkward questions. Lots of very awkward questions.

Some people seem to think it's correct to distort and exaggerate in order to close the door on the argument because they believe they're right. This is very dangerous. It is important for science that there is an open and mature discussion about these very important issues.

Apologies

@Suspicious Git: Actually I have to apologise. In turns out that Germany has 4 times as much autobahn as the UK has motorway. That makes the accident rates pretty much the same.

On relfection, looks like I should concede the aerodynamics point as well. The effect isn't significant enough to argue against raising the limit by 10-20 mph. And the motorway design should cope without any trouble.

Let's go for it. 80mph for the win! That's what everyone is doing anyway.

Mines the one with humble pie recipe in the pocket.

Some figures

@Suspicious Git. Yup, miles travelled is relevant. Surprised you didn't go and look. From the same EU source as above:

Germany 6613 fatal accidents / 682161 million km = 9.69 fatal accidents per 1000 million km

UK 3508 fatal accidents / 503318 million km = 6.97 fatal accidents per 1000 million km

_Still_ not safer.

@Adam 10. Yes. Some cars have more problems with lift at high speeds, but lift is still an issue for everyone else. From "Competition Car Aerodynamics" by Simon McBeath, p44. Production cars which do not carry airdams and spoilers generate around 70 - 80kg of lift at 100mph. That's net of any downforce generated. Ok, maybe that's not as big an effect as I was expecting, but my point is that once you start travelling faster than 70mph, the aerodynamic effects start to become increasing relevant, and the more you'll rely on the car's aerodynamics to keep the car under control. We not talking about motorway corners here... Imagine an emergency lane change at over 100mph? Or some oil on the road? As most people think that spoilers generate downforce (they don't, they reduce lift) I'm not confident that the average UK driver has the necessary knowledge and skills. They just _think _ they do.

As for high speed blowouts... this one's a classic: http://www.youtube.com/watch?v=Naa3qhFUlUE

Germany is pretty good example

Wrong. http://www.unece.org/trans/main/wp6/pdfdocs/RAS_2007.pdf

Check pages 29 vs 44 for Gemany and UK accident counts. As a percent of motorway accidents vs total accidents (for 2003):

Germany = 22646 / 354534 = 6.4%

UK = 8746 / 214030 = 4.1%

and for fatal motorway accidents it's worse again:

Germany = 811 / 6613 = 12%

UK = 217 / 3508 = 6%

So Germany has a 56% higher proportion of motorway accidents and a much higher fatality rate. That's NOT a better safety record.

Something about the laws of physics....?

Well, yes actually. 70mph is around the kind of speed where aerodynamic effects start to play a role in the car's handling. A car is effectively a crude aerofoil shape: flat on the bottom and curved over the top. This can generate lift and reduces the amount of lateral forces the tyres can generate to steer the car or keep it stable. Empty motorway or not.

80 mph. Ok not too bad, but imagine with a 30mph headwind...effectively 110mph. Mark Webber knows lots about this after launching into the trees at Le Mans one year caused by lift forces! http://www.youtube.com/watch?v=Ow3rxq7U1mA

Now there's now real chance of having an accident like that in a road car, but less grip doesn't help your chances of keeping it on the black stuff, especially if it's wet.

But of course, you knew all that. You're not just bombing down the M4 at 90mph on a windy day in the rain, completely oblivious to the possible dangers. No, not all.

And don't start talking about how it's fine to do whatever speed you want in Germany. Their accident rate is far higher as a result.

Submarine Commander's Exam Part I: Responding to Garden-Launched Threats

Q14) Your sonar operator has suddenly discovered a new enemy target at close range. They have identified it as a "Canopy" class attack gazebo. How should you respond?

a) Change heading to a collision course with the target and accelerate to ramming speed as soon as practical. It is only a gazebo and therefore offers no threat to your vessel.

b) Engage the target using appropriate and proportional force. For example, a high-explosive Mark IV Picnic Table with a 30 second delayed fuse.

c) Your sonar operator has mis-identified the craft due to its pseudo-gap superconductor derived magnetic sheilding. It is in fact the much larger, and more deadly "Pavillion" class. Command your helmsman to take appropriate evasive action and deploy weevil based countermeasures.

d) Cower in fear at the mere thought of a submersible stealth attack gazebo.

The "trick"

Agreed. The word "trick" is meant as a "nice technique for solving a problem". However:

Problem: The tree ring data went down instead of up.

Nice technique: Bin the bit that goes down as it's obviously wrong and graft on the themometer record instead.

The real issue being discussed is whether that technique was valid. Some say combining data in this way and not explaining it clearly was a bit dodgy. Not a nail in the climate change coffin I grant you. Not smelling of roses either.

I also agree that the report doesn't look like a whitewash. There seems to be some valid points there. The one about statisticians was something that the Wegman report also highlighted. The problem is these scientists don't like people asking awkward questions. Their "nice technique" for dealing with that problem: finger in ears... la la la.
