Exactly. Why ruin a chance for profit. Diabetes is the drug company's wet dream. cannot be cured, requires constant medication but takes a while to finally kill you (enough time to really make some money).

Well, any company that isn't making money from diabetes would still be interested in a cure. They don't care if some other company is making a profit.

As for "imprinted in the genes from birth to death" that is malarkey. Most of the genes in every person's makeup are never actually *expressed*,

The article is about cystic fibrosis. Cystic fibrosis is coded in the genes. End of story.

so the idea that because the potential for something is in one's genes means it cannot be suppressed is just silly.

Unfortunately, it's easy to say that just because it's in the genes doesn't mean it can't be "suppressed". But it turns out to be difficult to actually implement that.

This is a large part of what the actual article is written about: gene therapy sounds easy. But it isn't.

Doesn't fully explain warming this century.

Correct. Changes in total solar irradiance is, at most, a small contribution to global warming-- a few percent at most. We agree on this now?

Let me point something out: the amount of funding of climate science, and the amount of funding of organizations denying climate science, is roughly the same. Basically: for every scientist working on understanding climate, there is one person dedicated full-time to discrediting their work.

But the odd thing is: despite all the funding, none of work funded to attack climate science has yet come up with an alternate theory that is successful in explaining the data-- not even one that looks like it may some day come close to being successful.

With no actual evidence, you are assuming ideological and institutional bias as in input assumption. You're assuming NOAA is biased. NASA is biased. The National Science Foundation is biased. The National Climatic Data Center is biased. The Berkeley Earth Surface Temperature project is biased. The British Met office (formerly the Meteorological Office) is biased. The Climate Research Unit is biased. The Japanese Meteorological agency is biased. The Australian Bureau of Meteorology is biased. The Commonwealth Scientific and Industrial Research Organization is biased. The Centre National de la Recherche Scientifique is biased. The Max-Planck-Institut für Meteorologie is biased

Um, yes.A preponderance of biased organizations doesn't rebut my point.

Actually, I was listing the organizations doing work in climate science to point out how absurd what you were proposing is. All of the people actually doing science are biased? Do you really believe that? You don't have any credible evidence that any of these scientific organizations are biased, much less all of them.

Have you considered being as skeptical toward the people who are attempting to discredit the science as you are to the actual science? Who is telling you that all these scientific organizations are biased, and why would you believe them?

But, yes, if you assume that pretty much everybody who has ever studied the field is biased, and you can ignore their work... well, yes, you can ignore a heck of a lot of data, yes indeed.

That's why I'm waiting for future data.

Sorry, but no, you're not. No possible amount of data can ever convince you once you have decided that every science agency in the world is lying and you will only believe science that is not coming from scientists.

Oranges may be natural medicine, but they're not homeopathy.

The theory of homeopathy is that you cure a disease with a drug that reproduces the symptoms of that disease (that's the prefix "homo" in homeopathy-- "same"). So, oranges would only be useful as a homeopathy remedy if eating oranges gives you the symptoms of scurvy. ...and then homeopathy takes that drug and dilutes it until not a single molecule originating in an orange is in the drug. The homeopathy cure for scurvy would be "take a drink of water from a glass of water that was filled from a glass of water that was filled from a glass of water that had one drop of orange juice in it.

Which is 1.3 watts per square meter at the top of the atmosphere. That's almost the same as the current estimate of heating forcing from from elevated levels of CO2.

Nice back of the envelope calculation! but you're off by a factor of 6.

Solar irradiance is absorbed by the disk area of the earth, pi r^2. But the earth's surface area is 4 pi r^2. And the solar energy absorbed is multiplied by the (1-albedo). So you're off by 4/(1-a), where a is about 0.30 to 0.35.

... and then you're assuming the difference between zero solar activity, and current solar activity. But over the time scale over which the global warming we're discussing occurs, the change in TSI isn't that high. Here's a graph of the historical Total Solar Irradiance:
http://lasp.colorado.edu/home/...
and the variation between 1900 and 2015 is considerably less than that.

I hate to keep harping on the same things, but the effect of solar variability has been analyzed in mind-numbing detail in the last few decades, and it just isn't there.

Two obvious problems with the assertion. First, decades aren't a very long span of time. We don't know how much solar variability there has been before we started reliably measuring it late last century.

We know that it doesn't explain the warming this century.

Second, there's still that matter of the ideological and institutional bias

These have all made models and measurements confirming the greenhouse effect. ...isn't it slightly stretching credibility that all of these institutions-- and many others-- on four continents, all happen to be biased, and all biased in exactly the same way?

Comment TSI is not answer [Re:Proxy studies- still no...] (Score 1) 249

While there is indeed a higher total solar irradiance (TSI) with higher solar activity, that variation in irradiance is plus or minus one tenth of one percent. If, as you suggest, this is driving the observed warming, then there is a huge amplifier in the system.
But if there's a huge amplifier in the system, you have to explain why this doesn't amplify the contribution of infrared re-radiated by greenhouse gasses. Why would some input forcing get amplified, and other input forcing not amplified?
We measure all of this. When the scientists say "this effect can't account for the warming," this is because they are dealing with measured quantities.

(I will also note that TSI has a different warming signature from greenhouse effect: the greenhouse effect changes increase night time temperatures much more than TSI)

Basically, what you're saying boils down to "I won't pay attention to what the scientists actually say, and I haven't done a back of the envelope calculation showing it's plausible that they might be wrong, but I just refuse to believe them."

I'm a lukewarmist, I believe there is some effect.

And I'm a scientist. I look at the data.

But this is a huge factor to downplay.

One tenth of one percent.

And when you dismiss all data that doesn't agree with you-- which is what you're doing-- then it is completely impossible to ever overturn your conspiracy theory that all the science ever done on climate happens to be wrong.

Let me also note that apparently, it is possible to observe solar activity prior to direct observation by measuring carbon 14 in tree rings as a proxy. As a result, it is claimed that there were other periods of lowered solar activity from about 1000 AD through to the Maunder minimum.

So, what you're now saying is that the little ice age is not due to the Maunder minimum, but you're hypothesizing that it might have been due to some other sunspot minimum for which we have only proxy data.

Unfortunately,
(1) proxy data on solar activity is somewhat harder to interpret (see, for example, review article here: http://solarphysics.livingrevi... )
  (2) nobody looking at the record of proxy reconstruction has been able to find a firm correlation to global climate (although there are some regional climate correlations),
(3) there still isn't any accepted mechanism connecting sunspot number to climate,

For example, there were periods of alleged reduced solar activity between 1280 and 1350 and between 1460 and 1550.

This analysis looks like you have a result you want, and you're going back through the data trying to select data to try to fit the result. If this were actual science, you would need a correlation coefficient. How well does the variation in (proxies for) sunspot number fit the variation in (proxies for) climate?

All of the scientists doing the actual studies of this sort say the effects seen are far too small to explain the current warming trend: see, for example Solanki et al. 2004 study of sunspot numbers over the past 11,000 years and climate: http://www.nature.com/nature/j... "we point out that solar variability is unlikely to have been the dominant cause of the strong warming during the past three decades", or the review of dozens of studies here: http://www.skepticalscience.co...

But, returning to the topic, we seem to agree: the little ice age cannot be attributed to the Maunder minimum.

And when you dismiss all data that doesn't agree with you-- which is what you're doing-- then it is completely impossible to ever overturn your conspiracy theory that all the science ever done on climate happens to be wrong.

In fact, it's not. This is currently the best hypothesis that fits the data, including the dates. There may be a better hypothesis later. This is the way science is done; you gather data, make a hypothesis that fits the data, and see if later work confirms or overturns the hypothesis.

Paleoclimate resesearch, and most specifically modelling the climate variations in the late middle ages is indeed difficult, because not only don't we have contemporary measurements of all the input parameters, we don't have good measurements of the temperature, either. (Modelling contemporary climate is much more accurate-- we have lots of data on both the input (the solar output is well measured) and the climate (not just average temperatures, but diurnal variation, seasonal variation, latitude and longitude variation, etc. all of which must fit the modelling, although the AGW debaters only ever look at the year-by-year changes.)

The paper referenced, however does use a pretty convincing proxy for temperature change in the little ice age: they looked at the dead flora preserved in the Arctic ice cap. This dates the little ice age to a start in 1375-1400, with a second cooling period around 1450 AD. That is about the time when the Vikings abandoned their settlements in Greenland (they kept Church records; the last document in Greenland (a marriage certificate) was dated 1408.)

Unfortunately, this is THREE HUNDRED YEARS before the Maunder minimum. So it's really hard to think that the Maunder minimum caused the little ice age.

So, here's the summary.
1. There is no well-understood mechanism connecting sunspot numbers to climate.
2. The only connection between the Maunder minimum and the little ice age is a rough coincidence in timing.
3. But the more detailed examination of timing shows that the little ice age started much earlier.

Apollo 6 had two engines shut down early, but the upper stage burned longer to compensate, so the vehicle still made orbit.
The S-IVB didn't restart in orbit-- but since that was after it already made orbit, that counts as an in-space propulsion failure, not a launch vehicle failure.

Apollo 13 had a second-stage engine shut down early, but, again, the other engines burned longer to compensate, and the launch was a success. Launch wasn't the problem with Apollo 13.

So, I'd rate Saturn-V at 100% success rate as a launch vehicle, if the criteria for success is "getting the payload successfully into orbit".

Of course, with only 13 launches, it's not had as long a record as many other vehicles.

Yes, that's what they said.

However another explanation of the data is that many products fail early, and thus many of the people who buy products early in the release cycle ("early adopters") will buy many products that will fail. Is the set of "early adopters who adopted products that then failed in the market place" a set that can predict future failure in the marketplace? Well, they didn't show that.

It's easy to predict the past.

Certainly some early adopters pick products that don't take off, and mathematically some of these will have done it multiple times.
But the article claims that some people are actually predictors-- that their product choices have predictive value for product failure.
Is this actually true? It's easy to select out a set of people who have bought failed products, and then cull out of that set the ones who have not also sometimes bought successful products. But is this group statistically able to make future predictions?
I'm doubtful. Clearly, the way to not select products that don't grab a market niche... is to not be an early adopter. Lots of products fail; if you're an early adoptor, you're likely to be adopting failed products. If you instead wait to see where a product is going before buying-- you never buy products that fail a month after launch.
