Fascinating about the pressure in the suits. Do they have to step down over time to the lower pressure, like an ascending diver, to avoid decompression sickness? Or is the space vehicle maintained at some intermediate pressure?

The ISS is at standard sea-level pressure of ~14.7psi. The difference to get to the pressure required for the space suits isn't drastic. Astronauts do a pre-breathe on pure oxygen to purge their blood of nitrogen, but that's really all that's required.

Speed and atmospheric density are entirely relative in skydiving.  In fact, flying together in formation is called "relative wor"k.  I wouldnt think the air pressure against the body due to speed at low density air would be a problem.  I'd think equipment failure would be the worry.  Others have died on the way up to challenge Kittenger's record, but that was a long time ago.

Rebecca mentioned Microsoft was one of the supporteds of Heartland.   That did not sound right to me.   Read  this
for update on the issue.

First point, there are lots of possible contributors to weakening public belief in the climate change consensus. These would include the activities of organisations like the Heartland Institute, media content provided by the Murdoch press, and

Yes.
(my guess) disenchantment with decades of failed dire predictions.


Such as what?

We have seen a 30% drop in the living planet index since 1975, a conservatively estimated 160,000 human deaths per year in 2000, and a quartering of the northern summer sea ice volume since 1979, with the high casualty high cost tipping point of the loss of the Northern Summer Sea ice looking unavoidable.



Most people would call that moderately dire actualities.

Second point, my (very limited) understanding of Heartland's involvement with the smoking/cancer link was it was actually on the second-hand smoke/cancer link.


That's certainly what its been recently. Perhaps I should have said that smoking-cancer link denial only killed the useful idiots and their children, whereas climate change denial is killing everyone.

I'm not sure what you mean by this... Given the complexity of the system, long term climate predictions have been reasonably accurate so far - at least those that have received a reasonable amount of support. The really "dire" projections are for the second half of the 21st century anyway, so how could they have failed to begin with?

Mainly, yes, but there are several veterans at (or supported by) heartland who were big players in the tobacco wars, such as Singer (and previously Seitz). Besides that, Heartland is just one example of a substantially sized network of these think tanks. According to Oreskes et al, one of the first of its kind was the George C Marshall institute, which was very active during the tobacco wars. They're all pretty similar in terms of their activities and the stances they take on environmental/big government topics.

Just listened to the podcast, and all I can say is "wow."  Rebecca really is a walking, talking logical fallacy.  First of all, let's set aside the incalculable uses of "guilt by association" as it relates to Heartland, rather instead we should focus on the fact that there is not a shred of critical thinking going on throughout her monologue.  Heartland thinks that intermittent exposure to second hand smoke will kill you, so they must be wrong about everything?  They are certainly not alone in that observation, btw, as much as I hate cigarette smoke.  Not everyone who questions epidemiological studies like this are paid hacks, many simply are statisticians who are angered by politically motivated science.

It seems that Heartland is rather attracted to the idea of debunking science that is deemed too "politically correct" to question.  Does this indict them as liars?

Rebecca insinuates that being funded by "corporations" somehow condemns an organization to deceit.  This is funny, because most NGOs receive massive donations from corporations.  Is Greenpeace corrupt by virtue of the fact that it receives corporate donations?  Or anonymous large donations?  Rebecca is full of woo.   

Steve is downright gullible, but the rest of the crew is playing the role of the silent majority.  Evan did not say a word, to his credit.

Rebecca clearly believes that it is not possible for someone to honestly have doubts about the Global Warming industrial complex.  Despite the fact that we are regularly seeing credible scientists breaking with the dogma, including those that defected from the APS over abolutist climate change dogma.

I have never seen a serious discussion of the failings of the climate change lobby, nor consideration of the fact that perhaps a slight majority of the skeptic community thinks that the climate zealots are full of bunk.

You cannot deny the fact that 19 of the 20 models that the IPCC uses are outide of their confidence intervals, on the high side.  They simply have failed to predict anything related to climate over the past decade.

...so how does a legacy of failed predictions grant them absolutist trust?  It should not.  It should warrant them scrutiny from true skeptics.

I do not think Rebecca is a true skeptic.  After all, ThinkProgress confirmed it, right?  That is roughly like saying the Huffington Post confirmed it.

Close your eyes and listen to her monologue again.  Imagine that she is, in fact, talking about Gleick et al "trying to create confusion...trying to create controversy where there is none...using PR tricks."  It is hilarious.  She is, to a word, describing the desperate tactics of the climate alarmists.

It is a pretty crude indictment of her thought process, and ability to shed critical thinking when the moment requires.

It is widely accepted among the rational community that Gleick forged these documents.   It was such a low IQ hack job that only a hack zealot would fail to see the signs....

Rebecca failed every test of a skeptic...too bad.

Honestly, when I heard the segment on Heartland, my first thought was that Rebecca and the rest of the guys were doing a poor job of being fair to both sides of the issue and that they used some logically fallacious arguments.

But then I realized maybe they weren't trying to make arguments or present a controversial subject, but were instead just chatting amongst themselves as friends on a subject they were already largely in agreement on. When you're doing that, you're not committing fallacies because you're not even making arguments.

I believe that's how the show is supposed to feel anyway, so I didn't worry about it. I can see how listeners might get the wrong impression, but if I'm right about the intent of the segment and the show in general I don't think the criticism is warranted.

It is important to use critical thinking.

Heartland thinks that intermittent exposure to second hand smoke will kill you, so they must be wrong about everything?


No, Heartland are paid to spread doubt that the science shows that intermittent exposure to second hand smoke is associated with a drop in life expectancy.

They are certainly not alone in that observation, btw, as much as I hate cigarette smoke.


It's not about being alone or not. The point is that they are a group that is paid to disseminate counterscientific misinformation.

Not everyone who questions epidemiological studies like this are paid hacks, many simply are statisticians who are angered by politically motivated science.


This is true, but Heartland isn't a research institution, and it doesn't publish papers on epidemiological studies. Their interest in the matter is as paid hacks.

It seems that Heartland is rather attracted to the idea of debunking science that is deemed too "politically correct" to question.


Scientific debunking is done through the scientific process, and political correctness has very little to do with it. If there is a flaw that you have spotted in the published literature, or the current understanding, demonstrating this is a paper is a good and useful thing to do. Heartland does not do this. They are not debunking science. They are taking unscientific opinion directly to the unscientific public, and, it seems, into schools.

Does this indict them as liars?


Rebecca didn't offer an opinion on whether they are liars, so I won't in this defence of her position. But certainly what they are saying is not the scientific mainstream.

Rebecca insinuates that being funded by "corporations" somehow condemns an organization to deceit.

I don't think that that's the insinuation. I think that because they are popularising ideas about climate change and smoking that are counter to the scientific evidence, they are an organization of falsehood.

The corporate sponsorship is merely the motivation.

This is funny, because most NGOs receive massive donations from corporations.  Is Greenpeace corrupt by virtue of the fact that it receives corporate donations?


No. But I don't think that that's the line of evidence that has been applied to Heartland.

(And while Greenpeace is opposed to Nuclear power, and I think there's not a lot of scientific basis to that position, the basic tenet that we should be trying to preserve biodiversity does have a strong scientific backing).

Or anonymous large donations?


Again no, and Greenpeace is very careful to screen its donors.
"The organization does not accept money from governments, intergovernmental organizations, political parties or corporations in order to avoid their influence. Donations from foundations which are funded by political parties or receive most of their funding from governments or intergovernmental organizations are rejected. Foundation donations are also rejected if the foundations attach unreasonable conditions, restrictions or constraints on Greenpeace activities or if the donation would compromise the independence and aims of Greenpeace." - Wiki

Rebecca is full of woo.


If this is the conclusion that is supposed to flow from what you have said, its a non-sequitur.

Steve is downright gullible, but the rest of the crew is playing the role of the silent majority.

Steve is an experienced skeptic and an academic. I'm sure he makes thinkos, but I don't think you could correctly classify him as more gullible than an average man. What do you think makes him gullible in this case?

Evan did not say a word, to his credit.


An unusual thing to give someone credit for.
"Never be a spectator of unfairness or stupidity." is ethical advise from the late, great Hitch.

Rebecca clearly believes that it is not possible for someone to honestly have doubts about the Global Warming industrial complex.

I don't think that that's correct. And I think that she also made it clear that she doesn't have enough information to know if Heartland are dishonest.

Their positions, and their PR activities, however, are to propagate a view that is counter to the scientific understanding.

Despite the fact that we are regularly seeing credible scientists breaking with the dogma, including those that defected from the APS over abolutist climate change dogma.


There will always be dissenters in science. However, dissenters in this field make up about 0% of published papers, 0% of scientific organisations, and 3% of publishing climatologists.

Those "defecting" from the APS don't, of themselves, show that climate change is not anthropogenic any more than the existence of scientists at the discovery institute show that evolution is not real. The way to decide that is not to point at individuals, but the main body of scientific evidence. Individuals are often wrong, but the scientific process corrects errors.

I have never seen a serious discussion of the failings of the climate change lobby, nor consideration of the fact that perhaps a slight majority of the skeptic community thinks that the climate zealots are full of bunk.


Probably true, but also irrelevant to the state of the science.

You cannot deny the fact that 19 of the 20 models that the IPCC uses are outide of their confidence intervals, on the high side.


The IPCC doesn't use models, because they don't do research. They merely publish a summary of what the scientific community has learned about climate change.

They simply have failed to predict anything related to climate over the past decade.


Actually there are many papers that show that the past decade is perfectly in line with current understanding.

Have you read this one?: Reconciling anthropogenic climate change with
observed temperature 1998–2008


...so how does a legacy of failed predictions grant them absolutist trust?  It should not.  It should warrant them scrutiny from true skeptics.


I think that in the face of bodies arguing against the scientific understanding, but not using science, our first reaction is quite rightly to question the counterscientific group before the scientific one. Extraordinary claims and all that.

Especially in a field as prolific as climate science. It's not at though there are huge gaps that haven't been considered or tested. There are certainly unknowns, but with over 100,000 papers published there is also a body of evidence.

I do not think Rebecca is a true skeptic.  After all, ThinkProgress confirmed it, right?  That is roughly like saying the Huffington Post confirmed it.


I'm sure that even the best skeptics make thinkos. But if you're argument is that no true skeptic would back the science on global warming, you're making the no true Scotsman fallacy.

Close your eyes and listen to her monologue again.


It's a podcast. Closing your eyes doesn't make any difference.

Imagine that she is, in fact, talking about Gleick et al "trying to create confusion...trying to create controversy where there is none...using PR tricks."  It is hilarious.  She is, to a word, describing the desperate tactics of the climate alarmists.


It is a common practise for pressure groups such as Heartland to accuse the scientific side of the same tactics that they engage in. It leaves the impression with the public that since everybody said everybody was using PR tricks, so they probably both were, so there's two sides to the argument.

In actual fact science isn't much motivated by PR tricks. Pressure groups are though.

It is a pretty crude indictment of her thought process, and ability to shed critical thinking when the moment requires.


I think that you're mistaking her analysis of the situation with a description of why we believe the science. It wasn't a step-by-step for how we know that Heartland are spreading misinformation, but a description of how. Most skeptics already know that a science or evidence basis is generally the correct one.

It is widely accepted among the rational community that Gleick forged these documents.   It was such a low IQ hack job that only a hack zealot would fail to see the signs....


Heartland says one was forged. (The original one that motivated Gleick to seek verification by human-engineering Heartland). But Rebecca's talking points were substantiated by documents that were not claimed to be forged.

Rebecca failed every test of a skeptic...too bad.


I didn't even know a full set of tests for being a skeptic had been published, so I can't comment on which ones she has passed or failed. Do you have a link to this list of "every test of a skeptic"? Thanks.

(my guess) disenchantment with decades of failed dire predictions.


Such as what?


Mr Wombat, I take it from your moniker that you are Australian, as am I. So I'll use an Australian example. But, first, let me remind you that there is no point in distinguishing between the following:

- the research of real climate scientists
- the research of other real scientists which attempts to determine the effects of climate change on other matters (disease, species ranges and survival and so on)
- the pronouncements of real scientists about their research
- the pronouncements of activists scientists about other scientists' research
- the media articles and headlines

(I was going to put 'the politicians' as another item, but then I remembered that nobody ever really trusted them in the first place.)

Political action in a democracy depends, eventually, on public support. Activist scientists, political players, some NGOs, recognise this, which is why they bemoan any prominence ever given to 'climate sceptic' views in the media. It's why Heartland is viewed as a danger, because it seeks to sway public opinion.

Generalising horribly, the public are not scientists, nor are they interested in the intricacies of the science. That's what some political scientists would call 'rational ignorance'. But neither are they stupid. If a danger is forecast, long, hard and repeatedly, and it fails to  ensue, eventually they start to disbelieve the forecast.

But they are not reading the climate scientists' peer reviewed papers, full of qualifications and error bands. They are getting the entirety of their information from headlines and articles in the media, and from talking heads. The talking heads are almost entirely activist scientists and NGO people. The actual research is irrelevant to them.

So, consider Tim Flannery, an activist non-climate scientist (he's a palaeontologist). He prattled on for years about how the recent drought was the new norm for Australia. The last two years have seen widespread flooding. The ABC News this evening informed me that here in Canberra we received today, on the first of March, more rain than is the average rainfall for all of March. The new dam wall at Cotter Dam, presently under construction to increase the dam's capacity, may be over flowed this evening according to the news. In a beautiful piece of irony, the construction of the desalination plant in Victoria, built to address the expected water shortages due to the shift in climate to one of reduced rainfall, and in lieu of dams because 'rains could no longer be relied upon', has been delayed by rain.

Your Andrew Bolts and Alan Joneses have been reminding their huge audiences of Flannery's claims, and those of others. They don't even have to exaggerate.

So, do the public say, well, Flannery's just one rogue prognosticator, but we can trust everyone else? Hell, yes. For a while. But others weighed in on his side. More importantly, the moderate knowledgeable types didn't disavow his claims in any publicly obvious way. We can be reasonably confident of this because if, say, David Karoly had done so, Bolt would have highlighted it. And then the Australian Government gave him an imprimatur of authority by making him chief climate commissioner.

My guess is that as a strategy exaggerating adverse outcomes and expressing higher levels of certainty than are warranted may help someone achieve their aims of ginning up public support. But it's a short to medium term strategy. If you express excessive confidence in outcomes that are, in fact, uncertain, then as time goes on the chances of being shown up by events increases sharply.

Incidentally, I note that in a recent lecture Sir Paul Nurse, head of the Royal Society, did actually point out that the many catastrophic predictions weren't within what he called the 'consensus view':

Quote
Look at the debate about climate change. The majority of expert climate scientists have reached the consensus view that human activity has resulted in global warming, although there is debate about how much the temperature will rise in the future. Others argues that warming is not taking place at all or that it will happen in a catastrophic way, but they have failed to persuade the majority of climate experts, who have judged the scientific arguments made to support these more extreme views as being too weak to be convincing.

http://royalsociety.org/uploadedFiles/Royal_Society_Content/people/fellows/2012-02-29-Dimbleby.pdf (p.7)

Pity this didn't happen more often and earlier. Without the failed catastrophic predictions, things might be different.

I should have noted that it is not only supporters of the consensus who have failed to repudiate their nutty fringe, the other side has generally been the same. On the climate sceptics' side there is a range from your 'lukewarmers' (a term used by Matt Ridley to describe himself) to weird and wacky conspiracy theorists.

What reminds me of this is that in a fitting symmetry to Sir Paul Nurse's rejection of the catastrophists I mentioned, Fred Singer has a recent article up in which he attempts to distinguish between 'climate skeptics' and 'deniers':

Quote
I have concluded that we can accomplish very little with convinced warmistas and probably even less with true deniers.  So we just make our measurements, perfect our theories, publish our work, and hope that in time the truth will out.

- the pronouncements of real scientists about their research
- the pronouncements of activists scientists about other scientists' research
- the media articles and headlines


There is every point in distinguishing between those. The erosion of the value of expertise being pushed by the worst of the media and by American culture should not be affecting the sceptic community.

So, consider Tim Flannery, an activist non-climate scientist (he's a palaeontologist). He prattled on for years about how the recent drought was the new norm for Australia.


He explained that climate models generally produced a strong ENSO under warming, and that that would result in longer droughts, but also heavier flooding rains.

But certainly that the sort of droughts that we saw from 2001 to 2009 around the country will become regular events was pointed out by Flannery.

It is important to note that this is still in line with the best science that we have.


The last two years have seen widespread flooding.

And these events were also predicted by Flannery.

Your Andrew Bolts and Alan Joneses have been reminding their huge audiences of Flannery's claims, and those of others. They don't even have to exaggerate.


Exaggerate? They need to outright lie if they've been saying that the recent flooding is counter to Flannery's predictions. And while I don't listen to either, I see from Mediawatch, that that is their normal standard of journalism.

And that is certainly problematic. Journalism is supposed to be a profession. Having stakeholders pay for a particular point of view to be presented is no more ethical than a lawyer taking money to throw a case, or a doctor taking money to advise for an experimental treatment. In the latter two cases the illegality is clear. In the former, it appears that we need more regulation. The death threats and hate mail that is poured upon Australia's climate scientists who have dared to appear (and have their expertise and advice misrepresented, and vilified) on these shows demonstrates the consequences of allowing a profession to forget the ethics at its root.

Incidentally, I note that in a recent lecture Sir Paul Nurse, head of the Royal Society, did actually point out that the many catastrophic predictions weren't within what he called the 'consensus view':

Wow, You've data mined the internet for a speech that suggests that climate change isn't going to "happen in a catastrophic way". And you've found one by a cell biologist and geneticist, by taking a bite out of a part of a speech in which he is talking about taking action based on the consensus view: "It is impossible to achieve complete certainty on many complex scientific problems, yet sometimes we still need to take action. The sensible course is to turn to the expert scientists for their consensus view."

There isn't a scientific definition of whether are particular path of climate change is "catastrophic" or not. Conservative estimates put the death toll at 160,000 per year in 2000. I'm prepared to informally call what is happening moderately catastrophic already.
