I'm sure all the CO2 isn't exactly HELPING, but...

"The climate in the Antarctic stratosphere has been completely controlled by CFCs and cosmic rays, with no CO2 impact. The change in global surface temperature after the removal of the solar effect has shown zero correlation with CO2 but a nearly perfect linear correlation with CFCs - a correlation coefficient as high as 0.97."
Data recorded from 1850 to 1970, before any significant CFC emissions, show that CO2 levels increased significantly as a result of the Industrial Revolution, but the global temperature, excluding the solar effect, kept nearly constant.
I'm so confused. Obviously there are tons of studies that show CO2 levels have skyrocketed in the modern era -- but isn't there also data that correlates CO2 levels with global temperature increases? Does this study throw the entire "CO2 as primary culprit" theory out the window?
Also, is the International Journal of Modern Physics B peer-reviewed? If so, how did this extraordinary claim get past the peer review process?

Yeah, he doesn't provide any compelling evidence of how CFCs would operate so well as greenhouse gasses at their present concentrations. We've got plenty of evidence of how CO2 does. He doesn't have long-term records of CFC concentration, like we do for CO2. GCMs that include CO2 as a forcing effect work and make predictions in line with observation - they haven't required CFC forcing to do this. And claims of recent temperature decline are a little bit...dodgy.
It's science. But it is incomplete, and extremely over-played.

Waterloo's science departments are not that big - "physics and astronomy" is one department and I believe "biology and chemistry" is another. His past papers have been about radiation effects on human tissue, thus I guess he works in both departments.
Still, as a Waterloo alum, not Waterloo's finest hour. Yay for academic freedom I guess.

oh, whoops, I guess I really should check first - biology and chemistry are separate departments, but as I said, science overall is relatively small at Waterloo compared to engineering, math, arts and lots of other stuff. It's a solid school, but it's not Waterloo's backbone.

I would guess that it wasn't as much a matter of CFCs/ozone depletion creating a 'greenhouse effect' in the sense that the're acting to trap heat as much as it's a matter of letting a lot more heat in in the first place, just in the form of UV not IR. (as UV photons have about um (quick math) ~6-8 times the energy of IR photons, this could add up quick) Once the UV hits the ground it can be re-emitted as heat...like being microwaved :D
Of course, I have no idea how much more UV we're getting thanks to the hairsprays of the 70's as far as how much heat that translates to.
So yeah, I was on the fence about posting this, and am prepared to file it under 'utter BS', but I could also easily see this as at least a contributing factor to global warming even if it's not the everything's-gonna-be-just-fine replacement culprit.

So everyone's entitled to their opinions but this is crazy talk. Waterloo has a tiny department for geological engineers and that is really, really far removed from the Science faculty. Waterloo's CS department helping NSA wiretapping? Borderline probable. Collusion with oilsands producers? Extremely unlikely. There are numerous Canadian universities far more involved with the oilpatch than Waterloo, primarily due to simple physical proximity.

But the concentration of CO2 in the atmosphere is much higher than CFC's.
The elephant in the room, however, is that while CFCs are decline because they have been replaced by HFCs, HFCs are just are serious greenhouse gases as CFCs. The author's claim that everything will be hunky-dory because of the Montreal Protocol shows a serious error, above and beyond the physics.

Echoing what GuyZero said, this talk about Waterloo being bought off by the oil industry is rank horseshit. Point to a donor page that shows big energy companies like to donate to schools that churn out really good engineers? My heavens! And how clever of you -- you've seen through their ruse, you meddling kids.
Anyhoo, the University of Waterloo is also home to the Centre for Ecosystem Resilience and Adaptation, the Interdisciplinary Centre on Climate Change, a fantastic Environment and Resource Studies department, and who knows what all else. It is, in other words, a top-tier public university sponsoring a wide range of research. And one physics prof who does sloppy-as-hell research on climate change, evidently.
Suggesting the whole damn school is in the bag for Big Oil doesn't make you sound wise and knowing; it makes you sound like you haven't a clue what you're talking about.

And now that I look at it, the smoking-gun list up SysRq links to is a water pistol. ConocoPhillips donated less than 100K, which to a global energy firm isn't even a quarterly catering budget. I'm sure they spend nearly that each year just on the logoed ice sculptures they put on the banquet tables at self-congratulatory galas here in Calgary.

First of all, way to cherrypick the smallest donation. Did you notice the $600,000 (minimum; potentially $1.249 million) from Suncor? Not to mention all the other oil companies on the list, and whatever individual donors they may have also funnelled through?
And, seriously, your line of reasoning makes zero sense. Being easily able to afford a donation doesn't mean the recipient isn't grateful for it.

I work at a university that has several researchers who are highly regarded for their work on climate change.

I'm confused about why Lu asserts that global temperatures have cooled since 2002. Most of what I have read agrees with this. Is Lu referring to the little dip at the end and concluding that that little short series is evidence of cooling? If so, he has major problems in understanding how time-series work.

Just how do you imagine that general donations to a University fund of a few hundred K translate into research favorable to the donor? I mean, spell out the pathway that gets from the University President being made aware that X-donor donated, let us say, 200K to the campus to research favorable to that donor's business being published in a peer-reviewed journal by an academic at that university.

It is my understanding that molecule for molecule, CFC's are far more potent "heat trappers" than CO2. But the concentration of CO2 in the atmosphere is much higher than CFC's. So these two factors compete for control.
I heard one theory (from a real atmospheric chemist), that the proliferation of "new" molecules was a serious problem. There are thousands of compounds with measurable concentrations in the atmosphere that are 100% man made. While the concentrations are low, the problem comes from the fact that they absorb at many different places on the spectrum, and the fact that it's the first little bit that absorbs the most (Beer's law - transmission is log proportional to concentration).

Well, it does make zero sense that way. My point was not that those donations were insignificant to a single recipient but that they weren't directed to individual recipients -- they were small and seemingly unspecified donations. And when the wildly lucrative fossil fuel industry wants to buy influence at a university, it does not make a general donation in the low six figures or smaller to a whole school; it does stuff like this.

Gotta love that one. Rebuttal: You can have all the artificial co2 sources in your backyard. Enjoy your 'natural' environment :)
In the 1970's they called the shit that went into the air 'air pollution'. The fact that we have to build pipes to take the byproducts of human activity away from our lungs or nose should tell us that limiting the byproducts, if not the activity, that makes those pipes necessary is a nice idea all on its own.

Oh, this again. He's been working on this theory on and off for years now and still hasn't really come up with a plausible physical mechanism for it.
If there really is global cooling starting now (which is statistically dubious) then we'll know for sure in a few years (much more likely is that it's a blip in a few but not all of our best global temperature time series that'll fade away) and then maybe his theory will bear further examination).
That said, the idea that this is somehow being sponsored by Super Sekrit Tar-sand Agents is a straight up Alex Jones style Shire pipe-weed fever dream.
