Reply to “Comment on ‘Cosmic-ray-driven reaction and greenhouse effect of halogenated molecules: Culprits for atmospheric ozone depletion and global climate change’ by Dana Nuccitelli et al.”
Abstract: In the Comment by Nuccitelli et al. , they make many false and invalid criticisms of the CFC-warming theory in my recent paper, and claim that their anthropogenic forcings including CO 2 would provide a better explanation of the observed global mean surface temperature (GMST) data over the past 50 years. First, their arguments for no significant discrepancy between modeled and observed GMST changes and for no pause in recent global warming contradict the widely accepted fact and conclusion that were reported in the recent literature extensively.
Second, their criticism that the key data used in my recent paper would be “outdated” and “flawed” is untrue as these data are still used in the recent or current literature including the newest (2013) IPCC Report and there is no considerable difference between the UK Met Office HadRCUT3 and HadRCUT4 GMST datasets. The use of even more recently computer-reconstructed total solar irradiance data (whatever have large uncertainties) for the period prior to 1976 would not change any of the conclusions in my paper, where quantitative analyses were emphasized on the influences of humans and the Sun on global surface temperature after 1970 when direct measurements became available. For the latter, the solar effect has been well shown to play only a negligible role in global surface temperature change since 1970, which is identical to the conclusion made in the 2013 IPCC Report.
Third, their argument that the solar effect would not play a major role in the GMST rise of 0.2°C during 1850–1970 even contradicts the data and conclusion presented in a recent paper published in their Skeptical Science by Nuccitelli himself. Fourth, their comments also indicate their lack of understandings of the basic radiation physics of the Earth system as well as of the efficacies of different greenhouse gases in affecting global surface temperature. Their listed “methodological errors” are either trivial or non-existing. Fifth, their assertion that “the climate system takes centuries to millennia to fully equilibrate” is lack of scientific basis.
Finally, their model calculations including an additional fitting parameter do not reduce the discrepancy with observed GMST data even after their adjustments. Instead, their modeled results give a sharp GMST rise over the past 16 years, which obviously disagrees with the observed data.

“they make many false and invalid criticisms”
How ironic, you can say this for just about anything Dana and co. says.
Whoever is writing this (that’s unclear because they’re not named) is clearly very angry and that has played havoc with their clarity of expression.
If they could take a few minutes to go back over the piece and give us some detail and context and just correct a few grammatical points, it would be much more effective and informative.
Original paper By Q.-B. Lu

Presumably it by Q bin lu who has written numerous interesting articles about the cosmic ray theory

It needs explanation though as it doesn’t really seem a stand alone post in this format

From the conclusions …
Yet another Dana disaster. The boy has the knack of unerringly being wrong but he did win the climate prat of 2013 award.

At least Nuttercelli spelt his name right!
We should start a Dana fan-club. He never ceases to entertain.
It’s nutty. Which tells you the competence and comedy all in one person.
Pointman:
Thankyou so very much for the link in your post at June 19, 2014 at 4:28 am.
I had not read it and as I did I laughed so much that real tears rolled down my face.
I copy the link to here to help others who have not read it and want to share the joy.

There is so much that is good in it, but my personal favourite is not in the part about Nuccitelli; it is the section concerning “anusplierectomy”. Wonderful! Truly wonderful! Thankyou.

Nuccitelli is a fool, no-one has any respect for his views – not even the most rabid alarmist would hold Nuccitelli up as an example of anything other than a complete slobbering imbecile – he may actually be brain-dead. there’s a reason he looks like a zombie (sorry zombies).
Those supporting Nuccitelli here are actually sceptics pretending to support him in an effort to make warmists look even dumber than they are (the same as they do for Mann). Nice work guys.
@richardscourtney:
Glad you enjoyed it. Humour is the one weapon we have that they don’t; saving the entire Earth is a really grim business you know …

@richardscourtney
Agree 100% with your appreciation of the Pointman school of comedy but he does have a dark side too!

I love how the warmistas unerringly correlate GMST increase with technological advancement, and then use hyperbole and hysteria to give the central planners the excuses they need to control us. Thank you, and by the way, your 5 year grant has been approved..
Dana never tires from showing how little he knows about so much , an man truly amazed by his own delusion of his own brilliance.
Seems to me IPCC AR5 refers to events such as the climate tipping point and major ice sheet melting taking place in geologic time where “sudden” is at least a thousand years.
I don’t have time to go over this paper in detail right now but a couple of zingers jumped out at me:
1 – ” … observations are inconsistent with the above predictions, indicating that the current photochemical theory of ozone loss is incomplete or incorrect. ”
That’s nice, but the second zinger really got my attention:
Holy Bleep! Is this person is saying that global warming is caused by CFCs? This would be earth-shattering if it were true. (Sorry for any hyperbole that may have crept in.)
@commieBob at June 19, 2014 at 5:43 am
The US EPA definitely think that halogenated gases are “greenhouse gas”
http://www.epa.gov/climatechange/science/indicators/ghg/ghg-concentrations.html
It’s as good a theory as CO2 controlling the climate. And better if the correlation is anything to go by.
But hey, correlation is not causation unless it advances the cause.
If CFC’s do cause warming, then there is hope that mankind could actually prevent the next ice age.

Ongoing stuff. IIRC previous paper was a reply to Grooß and Müller’s criticisms based on satellite data. See: http://wattsupwiththat.com/2012/10/08/a-paper-unifying-cosmic-ray-interaction-cfcs-ozone-and-warming
Usual cryptic drive-by from Mosher with a promise of ‘hints’ to follow but never followed up. What with nuts, cherries and chocolate sauce it’s beginning to look like yet another ice cream sundae. Would be nice for once to see some credible data and analysis to either back up or dispel these ideas.
I think we can now safely conclude that the melting ice mantra by the AGW is and was complete BS
http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/global.daily.ice.area.withtrend.jpg even the “warmist” CT site (probably no longer, but was), cannot withhold the data (BTW I doubt that CT is in any way prepared to risk losing face anymore over AGW). The usual AGW drivel stopped about 2 years ago, but they still have the iconic 2007 arctic melting video. Maybe they should remove it before people notice how stupid it looks LOL
Went and read the Lu paper. Interesting, but flawed. Makes the CO2 saturation argument to discount it having any effect. That is a misstatement about how the effect works. Then argues the photochemical UV/CFC effect cannot be primal. Weak statistics. The argues the alternate CRE/CFC explains everything from 1970. Correlation is not causation, and sure does not explain 1900 to 1970.
Nuccitelli’s rebuttal was pathetic. The better reasoned response is that we know from pre 1960 or so history that natural variation is a major climate driver, and we do not yet understand why or how. We also know the physics say CO2 can have had some additional effect since about 1960. But the pause shows that natural variation is still powerful, and also that the models run way hot because tuned to a period of also naturally rising temp. And we can say that the UV/CFC effect is real, that the CRE/CFC chemistry and effect are real, but that the Montreal protocol coinciding with the beginning of the pause cannot possibly be the full explanation for it since one has excluded natural variation from the discussion.
Both Nuccitelli and Lu should be faulted for ‘all or nothing’ blindness overlooking the elephants in the room.
Just for completeness, here is the link to the comment that Lu is objecting to,
http://www.worldscientific.com/doi/abs/10.1142/S0217979214820037
I agree with Rud Istvan that a more likely explanation of the pause is internal variability of the climate system. In my opinion the AMO gives a good fit to the climate history since 1850 or so, except of course for the superimposition of shorter-term quasi-cycles such as ENSO.
