This is always the problem with people imagining horrifying artificial intelligences that will snuff out humanity. To do that, you have to be motivated to achieve that end.

Not really. A self-sufficient AI could easily come to the conclusion that humans (and life in general) should be eradicated from a number of different avenues of thought. An AI could be incredibly subtle and patient about doing it as well. Humans aren't really good with subtle or patience, especially if the actions seem to be perfectly good and well reasoned.

Of course NASA is used to doing this.

The ocean below 1.24 miles hasn't warmed. The ocean above that has, and it turns out it has warmed more than originally thought: Link.

Doubled CO2 means under 2 degrees warming

"8th December 2010 13:24 GMT - A group of top NASA and NOAA scientists say that current climate models predicting global warming are far too gloomy, and have failed to properly account for an important cooling factor which will come into play as CO2 levels rise."

Yes, because a news site without links to the actual published research or subsequent scientific discussion is to be taken at face value. However, it didn't take much Googling to find that the so-called study being referenced in the link was authored by none other than Judith Curry, a well-known climate crank. Her work has been scientifically eviscerated many times over. In other words, she has no credibility.

The latest research, done by several different scientists at several different institutions over the past couple years seem to be averaging around 4C. The AR5 centered around 3C.

http://www.nasa.gov/topics/ear...
""Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data. "

Why would a 150 year melt cycle be "right on time" in warming world? Never mind somebody made the headline "Unprecedented melting of Greenland ice".

How can a cyclical even be unprecedented?

Again, you are mixing journalistic sensationalism with actual science. That being said, irregardless of the event, Greenland is experiencing rapid mass loss. There have been multiple papers on the subject.

I believe Mr. Hansen left shortly after this. I could be wrong but I think it was around that time.

This had nothing to do with why he left NASA. HE RETIRED. He mentioned his retirement several years before he actually left. He worked there for 46 years. Now he's following his passion as the director of the Program on Climate Science, Awareness and Solutions at Columbia University's Earth Institute.

What I don't agree with are the people who are using things like Malaria and HIV statistics to try and show how the media is playing up this issue.

You may not agree with it, but that is exactly what they are doing.

As/if more Ebola cases arise, the contractions will increase exponentially and they'll stop comparing this to "more serious diseases".

Not happening, at least not in countries with reasonable sanitary practices. Ebola is difficult to catch, and it has a high mortality rate. These two factors prevent it from becoming the next big pandemic. To wit, the guy who was first diagnosed in the US was in Dallas, a city of 1.5 million people. Out of those 1.5 million people, he infected two, and they were the nurses who were directly caring for him.

Yes Ebola is lethal, but so is EEE and yet I don't see you in a panic about EEE (and that's spread by mosquitos). You're far more likely to get EEE than Ebola (along with a whole host of other diseases). You're more likely to die falling out of your chair while reading this than die from Ebola.

What I don't understand is why they are letting doctors who work on Ebola patients back into teh country without being screened?

There are people arguing to shut down all travel from West Africa, even if that's too much in your opinion, at least screen these doctors.

Customs: What was your reason for leaving the country?
Doctor: I was treating patients with Ebola.
Customs: Due to national security, we can not let you into the country until you've been tested and cleared.
Doctor: But I have plans to go bowling in Brooklyn in about week!
Customs: You're retarded.

Chances are, the conversation wouldn't happen like that and the doctor would be understanding of the situation.
So why aren't we just doing that to begin with?

Because it would be ineffective. As has been mentioned numerous times, it's easy enough to lie and/or take a circuitous/non-documented route. Screening for possible Ebola victims would be about as effective as screening for terrorists: UST (Useless Security Theater).

What's really happening is climate destabilization. It really doesn't take a lot to destabilize the climate system; plus or minus 2 degrees is enough to bring on the heat or cause an ice age. But the real kicker is you don't even need to cause the whole delta. You only need to push the climate past a tipping point and the positive or negative feedbacks do the rest.

The climate is just like any other thermodynamic system. You add or remove energy from the system, it's going to destabilize until it reaches a new balanced state.

AIDS doesn't cause contagious blood, spit, diarrhea, and vomit to go everywhere. Ebola does.

AIDS doesn't infect health care workers who are treating patients unless there's a needlestick or sexual contact. Ebola does, with alarming frequency. Even if you DO have sex with someone with AIDS, it's not 100% that you'll get AIDS.

AIDS can't be spread by sneezing or coughing. It's possible Ebola *is*.

In terms of contagiousness, Ebola seems 10x worse. It's like saying "smallpox is no worse than chickenpox". Maybe if you put them both on a logarithmic plot and back up 50 feet!

The 1918 influenza outbreak killed an estimated 25 million people in it's first 25 weeks, and killed an estimated 50 million in the course of the year. It infected over 500 million people in total.

The regular yearly flu kills anywhere from about 4,000 to 40,000 people a year in the US and infects many many more.

And yet, you don't seem to be panicking about that.

Heart disease kills a million a year. Cancer kills about half that. Car crashes kill about 40,000 a year.

And yet you don't seem to be losing your mind over it.

In fact, there's a whole list of things that are more likely to kill you on a day to day basis and Ebola is right down there around lightning strike, terrorist attack, and getting hit with a meteor.

Well, since you seem to be content in wrapping yourself in tin foil you don't have much to worry about, do you?

Try sticking to the facts. If Ebola was anywhere close to how bad you're trying to make it most of western Africa would look like a mass grave. Strangely, it doesn't. Even with their piss poor conditions, poor sanitation, and customs which actively encourage the spread of the disease the numbers of infections has been small and limited almost entirely to the region where the outbreak started.

The current outbreak began in December of 2013 and has infected approximately 8400 people and killed about half of them.

By comparison the 1918 influenza pandemic during a similar period of time infected approximately 500 million people, with 25 million people killed in the first 25 weeks of the outbreak.

I don't see any reason to get whipped up into a frothing panic over Ebola, which is what you and the news cycle seem to want.

And we don't. As regards global climate we have models and data but we don't really understand what is going on here. We never have...

Correction. You never have. High school physics and chemistry is all you need to create a basic physical model to demonstrate planetary warming with increased greenhouse gas contributions. The first climate model to demonstrate planetary warming with increased greenhouse gas concentrations was formulated back in 1899. You read that right. Svante August Arrhenius, the father of modern chemistry, created the first climate model and was one of the first to predict global warming in response to human activities.

Global warming is not magic. It's not even new science. It's basic thermodynamics that even someone without a calculator or computer could figure out. That's why scientists don't bother having conversations with idiots/deniers. For their inanity to be even remotely correct would indicate that some of the most fundamental concepts of physics (laws of thermodynamics, conservation of energy, etc.) would also need to be incorrect. Now if they had really strong evidence to show that this was indeed the case, then great. Publish and get ridiculously rich. But graphturbation is not strong evidence, and neither are ridiculous conspiracy theories that make no logical sense.

No probably about it. By every known measure the planet has warmed over the past 150+ years.

We don't know for how much longer.

Yes we do. As long as we keep pumping more GHG's into the atmosphere the planet will continue to warm. And after we stop or at least get back to some sort of equilibrium the planet will keep warming for another 30-40 years due to climatological lag. Then it will stay warm until the system (or we) start taking some of the excess GHG's and getting them back out of the atmosphere.

We don't know how much warmer.

Yes we do. Climate sensitivity studies indicate that at our current rate of emissions we will warm the planet by about 4C by 2100.

We don't know how it's happening, mostly.

Yes we do. The basic chemistry and thermodynamics of how it's happening have been around for more than 100 years. It's not rocket science. A high school physics text gives enough background to create a basic model to demonstrate warming in relation to increased GHGs.

We don't know why it's happening.

Yes we do. Human emissions of GHGs. The level of GHG's in the atmosphere have increased greatly since human industrialization (isotopic analysis of carbon shows the source is fossil fuels). After that, physics does the rest.

That's climate in a nutshell.

Non-sequitur. What the science says and what the government does are unrelated.

Comment Re:please no (Score 2) 423

I think what annoys me the most about climate alarmism is the false certainty such as conflating opinion with fact. The second most annoying thing is the lack of scientific grounds for the arguments made.

"Alarmism" as you call it, is social. I've yet to read any scientific papers claiming we're all going to die.

As for your "lack of scientific grounds", that's just bullshit. The basic chemistry and thermodynamics were worked out well over a century ago. The first prediction of AGW was made by Arrhenius in 1899 (he also created the first climate model and is considered the father of modern chemistry). If you want to go further back you could talk a look at the preliminary work on greenhouse gas theory from Fourier (1825).

For example, the above two links in the parent post show considerable divergence between the models and reality (sea level and polar ice extent while substantially and suspiciously downplaying the temperature difference between model and reality). The "myth" is confirmed but the writer portrays it as affirmation of their desired conclusion.

Irrelevant. Those aren't scientific papers. They're not peer-reviewed. Any idiot on the web can say whatever they want. That doesn't make them a legitimate source of information.

Meanwhile the assertion that models fit past events is near irrelevant since that is data which is already known and it is expected that the models would have been adjusted in the first place to fit that data). For example, I can construct an interpolation of any temperature (or other numerical) data to perfect precision using an even degree polynomial of sufficiently high degree, yet it'll be completely irrelevant once I attempt any sort of extrapolation into the future (odds are good, about 50% I'd say, that it'll predict temperatures far below absolute zero by 2100).

Ignorance only hurts your argument. Climate models are physical simulations. They work based on physics, not some statistical curve fitting which is what you seem to be implying. Climate models are initialized with some historical set of conditions, and then run forward to see how well they model climate responses.

That's why physical models in general (fluid dynamic models, gravitational models, weather models, climate models, etc.) can be used for helping make useful decisions and research.

We see this attitude in action in the current story. First, the story noted that these models don't actually predict past events when they're run backwards from a current state. Then someone rationalizes that it's because the observations are wrong, not the models. This not only runs counter to your empty assertion that the models predict the known past, but also is profoundly anti-scientific.

You have terrible reading comprehension. The article (which isn't the paper) says the scientists used climate models to look into the past, not "run the models backwards". Running them backwards doesn't even make any sense. You can read the paper to see their methodology.

The issue the paper is addressing, which you fail to grasp, is that the the data from recent higher accuracy observations (namely the ARGO network) are reporting a lot more warmth than was previously estimated from earlier, lower quality observations. They then analyzed the discrepancies and discovered that global ocean heat in the upper 700m may have been off by as much as 25%, which would have potential impacts on things like CO2 sensitivity studies.

Here are two examples where the most FUD-inducing interpretations are used. The climate models are "too conservative" because they allegedly underplay sea level rise, but the corresponding inability of the models to predict temperature increase is not (though that means the models are exaggerating sensitivity of carbon dioxide temperature forcing, the most important of the unknowns in climate research.

You are viewing a climate model as a singular entity, which they aren't. A climate model is comprised of multiple physical models that interact to simulate the climate system. In addition, the model is only going to be as good as the data it gets. Some parts of the climate have a lot more data and are better understood than others.

All this and more is covered in the summary chapters of the IPCC. They go over the models, how they are run, accuracy, known unknowns, etc. Even if you think climate science is conspiracy created by Al Gore when he went back in time riding a velociraptor and threatened to club Fourier to death with a rubber baby Jesus, reading at least the summary sections would allow you to make much stronger arguments for your case.

Similarly, when models are shown to be out of whack with past observations (as they were with future observations), the interpretation is that the observations are wrong, not the models even though it is more likely to be the other way around.

The observations weren't "wrong". Did you even bother reading anything? The ARGO observations are higher resolution and more accurate. Even allowing for that they noticed a considerable discrepancy between the ARGO observations and the previous observations. That's what they investigated.

This profound inability to admit error is why I don't trust current climate models or the doomsday predictions they spawn in the least. That's why I'm going to wait a few decades and see what happens. If it genuinely is as bad as claimed, then we'll see something by then.

Error analysis is a fundamental part of any research, and climate science is no exception. You'll see it in practically every paper. Science is confidence intervals, not absolutes. Saying otherwise demonstrates a profound lack of knowledge and experience about how science, any science, is actually done.

There are no doomsday scenarios in climate science. We can certainly make living on Earth a hell for ourselves if we don't smarten up, but not single legitimate scientific source I'm aware of is predicting the end of the world, or even human extinction. So stop with that nonsense. It simply isn't true.

As far as the wait and see approach goes, I hear that always works out well especially when you're screwing around with climate system on the only planet we live on. By the time things are bad enough that even someone like you must face reality, it will be far too late to do anything about it. That's like getting a vaccination for polio after you're already paralyzed.

You know, if you could engage your brain for 5 seconds instead of going to your default ideology routine, you may be able to figure this one out for yourself. The oceans are not static objects. Ocean currents can and do have periods that can span a couple decades. These currents can bring warmer or cooler waters to the surface.

Form there, it's basic physics. If the air is warmer than the water, the water heats up. If the air is colder than the water, the air heats up. If the net energy balance of the system is positive, then the water (having much greater heat storage capacity) will gradually warm up over time. As the currents cycle there will be periods where air temperatures will be cooler and periods where air temperatures will be warmer. And again, if the net energy balance is positive then temperatures will stair-step higher and higher (which is what we've been seeing).
