Comment Re:Don't care, already turned off (Score 4, Insightful) 62

After the alert mechanism was misused in my state for an Amber alert for an incident hundreds of miles away, I turned these alerts off.

Exactly the same here: After I was woken up from sleep at 2AM by an Amber Alert for a child that purportedly missing 200 miles away (who turned out to be with her father) I turned the alerts OFF.

However, in their favor, the adjustments to the alert system also are going to improve the geographical targetting, so that they will be more narrowly broadcast to just the areas affected:

Comment It's a technical problem (Score 1) 192

There are also the small matter that due to glaciation there would have been much less plant life, and animal life to either consume or exhale CO into the atmosphere. In addition those same ice sheets also increase the albedo of the planet, reflecting more sunlight than it would have otherwise, which would also have impact not only on temperature but potentially the interaction of greenhouse effect in the atmosphere.

This is a good part of the criticism of interpreting her correlation. Much of the correlation comes during the retreat of glaciers from the northern hemisphere. But the glaciers have mostly already retreated from the northern hemisphere-- this effect isn't likely to operate.

That said I think it is a no brainer that there is obvious correlation of CO and temperature. Only that it isn't that simple in all but probably the models being built.

The modelers have a damned-if-you-do, damned-if-you-don't dilemma. When the models are simple, people snipe "but the models are too simple; they can't be right." And then when the models are more complicated, people snipe "but the models are too complicated; you can't understand all those feedback loops."

Heck the simple fact that there are Billions more mouth breathers on Earth are likely going to impact the CO levels regardless of industrialization and using sequestered carbon sources (oil, coal, wood, etc...).

Respiration turns out to be a pretty trivial source of carbon dioxide.

(Cutting down forests, though, may be more important effect.)

...The issue is, and always has been a political one and convincing less developed countries to not do what the developed countries did to get ahead, which as you can imagine is pretty hard to do.

If the developed countries find ways to maintain a high standard of living with less carbon usage, I think it's likely that the less developed countries will adopt the same approaches.

...It is all well and good for countries to try and limit their production of CO, but ultimately to do so they tank their own economies (and election hopes), for little good when other countries do not follow suit and are not about to.

It has been a right-wing obsession that reducing carbon dioxide emissions must "tank the economy" but I see no evidence whatsoever that this is the case. We are very very good at resource substitution. Energy is a resource. There is no physical reason we need to burn six tons of carbon per person per year to maintain our standard of living, we just happen to find it convenient to do so.

In the end, it really is a technical problem, and, hard though it is to believe it in this cynical era, we are actually very good at solving technical problems.

Comment Failure isn't failure... if you learn from it. (Score 5, Informative) 201

And that's different from NASA/Energia how?

Space ex has a failure rate 10 times worse. The FAA needs to step in and force them to take safety seriously.

Failing, as it turns out, is an effective way of trying new things and finding out what works. Painful, but very very effective.

The best thing about SpaceX is that they aren't afraid of failure.

The worst thing that could happen would be if the FAA steps in and no longer allows companies to fail. If you aren't allowed to fail, you're not allowed to innovate. The only way to take the chance of doing new things is by taking the risk of failure.

Or, to use a quote: “Only those who dare to fail greatly can ever achieve greatly.”

Look, we know Juno wasn't designed for this sort of mission and is not well equipped or positioned for it. But if researchers determine that its observations could help pinpoint more details of the plumes...

But they can't. Juno isn't a mission to look at Jupiter's moons, it's not in the right orbit to look at Jupiter's moons, it doesn't have instruments to look at Jupiter's moons. It's designed for looking at Jupiter and Jupiter's plasma and field environment.

Comment ice particles AND water vapour (Score 4, Informative) 92

Isn't vacuum always cold? I fail to see how it could have a temperature above 0K.

Vacuum in itself has no temperature at all. "No temperature" is not the same as 0 Kelvin.

The temperature of something IN a vacuum is determined by the sources heating it and the infrared radiation outward from it. Initially, water exposed to vacuum will start to boil; the boiling will reduce the temperature (losing the heat of vaporization), and the lower temperature will freeze the water. So, in fact, it will boil and freeze at the same time, resulting in ice particles AND an expanding cloud of water vapor.

I got cooled to absolute zero, but I'm 0K now.


Comment How to solve the problem (Score 2) 192

...then massive, costly, and punitive CO2 mitigation schemes become pointless and wasteful.

It is a political talking point that doing anything to address the production of CO2 will be "massive, costly, and punitive". Since the response of the fossil fuel industry has been "do everything possible to cast doubt on the fact that a problem even exists, and divert all attention away from realistic thinking about possible ways to address the problem", though, this has never been thought through.

The problem being that a non-existent 'climate crisis' allows governments, politicians, and their bureaucracies unprecedented powers and control that they will never willingly give up.

It is a right wing talking point that if climate change is real, then the only possible way to address it is to give "governments, politicians, and their bureaucracies unprecedented powers and control."

I find it amusing that the right wing's only approach to the problem is to say that if the problem is real we need to give governments more power. It's as if their political philosophies don't have any tools to solve problems other than "give the government more power."

Comment Million year time scale (Score 2) 192

I think you have that backwards. Snyder is saying that the historical record shows that the sensitivity of temperature to carbon dioxide is much HIGHER than the GISS estimates. Gavin Schmidt's comment is, basically, that her data shows correlation, not causation.

I took away from her study that, as far as she could extrapolate from the available data on climate/temperature cycles going back 2 million years, that we were pretty much smack at the point of the two curves one would expect during this point in time, so to speak, on both CO2 and temperature and from that lack of deviation from expected norms then suggesting that humans have had little if any significant effect on global temperature averages

In that case, you are misled by a misinterpretation of her results.

She looked at temperature and carbon dioxide with five thousand year averaging. Five thousand year averaging says absolutely nothing about the effects of industrialization-- we don't even show up in her data. With averaging on five-thousand year bins, you only see effects on time scales that are long compared to five thousand years.

, and that the warming that is occurring and will continue for a long time at pretty much the same average rate is pretty well inevitable given past history with or without human industrialization.

A more accurate statement of that : "The activities of humans over the last 100 years have not had an effect that is yet visible on a graph plotted over million-year time scales."

To which one could accurately add: "yet".

Seeing as how industrialization in it's entirety has failed to have been shown to appreciably affect global temperature changes

..enough to be evident over million-year time scales.

Comment Not indicted (Score 3, Informative) 401

This is completely bizarre. Assange is not currently wanted in the US. There is no indictment against him, there isn't a warrant for his arrest, and there is no request for extradition. I'm not sure how he can "agree to go to prison" when he hasn't been charged with a crime. The U.S. doesn't actually let people go to prison just because they want to; they have to be found guilty of a crime.

Assange is wanted in Sweden (although so far he's only wanted for questioning.)

Assange is wanted in Britain-- for jumping bail.

But he's not wanted for a crime in the U.S. He could agree to go to prison in Sweden or Britain-- why doesn't he volunteer to do that?

I think you've nailed it there. It's very easy for the security people to see things in black and white; that anything that gives them more power to stop the bad guys-- and there actually are bad guys here, you know-- has to be good, and anybody who tries to limit that power has to be bad.

What is scary is if Musk has already decided they will resume so quickly even if they have not determined the cause.

Everything SpaceX does is always attributed to Musk. The actual article attributes the quote to Gwynne Shotwell, president of SpaceX.

She was speaking at a conference. Somebody asked when they'd be likely to start flying again, and she gave a best guess. This is not a firm commitment to fly whether or not they have found and fixed the problem, it's just a best guess about how long the process will take.

My personal best guess is that a failure review for a non-manned system takes about six months (after their June 2015 failure launches resumed in December, for example) so I think she is a little optimistic, but she probably would prefer to err on the side of optimism.
