why would it if it couldn't heat it. see, you are truly the fool. to even ask that question proves your idiocy.radiation does not warm air. period.well fine, just post that evidence of that happening. See kinetic energy is heat, and right now, there is no hot spot in the atmosphere or troposphere
Just so we know you have some rudimentary knowledge on this....why don't you briefly explain what the hotspot is? Just roughly where it should be, and where the energy comes from, if it were to exist.
Then connect that to CO2 radiative physics.
radiation does not warm air. period.
Does radiation cool the air? Interact with the air in any way?
IR flows out to space. That's it. After absorbed and moved around via collision and emission.

You are claiming that the missing hotspot proves your point somehow.
Well, fill in the gaps by explaining yourself. Just a rough description will do.
the missing hot spot falsifies the greenhouse hypothesis and its bastard stepchild..AGW....the fact that you people continue to accept a hypothesis which has had predictive failures never ceases to amaze me...
One predictive failure is sufficient to send a hypothesis to the dust bin in real science....in pseudoscience, however, a hypothesis can have any number of predictive failures and remain viable so long as the funding continues...
Something you have been unable to produce.. Its not a model...I'd like the OP to explain precisely what he means by " SOLID, PHYSICAL, EMPIRICALLY observed and verified evidence". I assume by "solid" he means verifiable. Empirical and observed are redundant. But what, Billy Boy, do you mean by "physical"?
well great, point it out to us.The hotspot is not unique to greenhouse warming. It should be present with any warming. And it is.
I answered his question. you lie.the missing hot spot falsifies the greenhouse hypothesis and its bastard stepchild..AGW....the fact that you people continue to accept a hypothesis which has had predictive failures never ceases to amaze me...

JC failed to answer IanC's question. Can you give it a try? Here is his question again.

sure it does. again IR doesn't warm the air. just doesn't. and, you have no evidence it does. See, that fact alone, is what proves my point.radiation does not warm air. period.well fine, just post that evidence of that happening.

Well, fill in the gaps by explaining yourself. Just a rough description will do.
Tell me again, according to the AGW hypothesis, how this is supposed to manifest itself?the missing hot spot falsifies the greenhouse hypothesis and its bastard stepchild..AGW....the fact that you people continue to accept a hypothesis which has had predictive failures never ceases to amaze me...

From Atmospheric changes through 2012 as shown by iteratively homogenized radiosonde temperature and wind data (IUKv2) - IOPscience, a link provided in Climate Meme Debunked As The ‘Tropospheric Hot Spot’ Is Found
4. Conclusion
We have briefly described an update of the dataset published by Sherwood et al (2008), which brings the data to February 2013. Several modifications have been introduced, which have not had a large effect on estimated long-term trends in temperature but have enabled us to present a homogenized wind dataset in addition to that for temperature.
The warming patterns shown in the revised dataset are similar to those shown in the original study except that expected patterns now appear somewhat more clearly. These include a near-moist-adiabatic profile of tropical warming with a peak warming rate of 0.25–0.3 K/decade near 300 hPa since either 1959 or 1979. This is interesting given that (a) many studies have reported less-than-expected tropospheric warming, and (b) there has been a slowing of ocean surface warming in the last 15 years in the tropics. We support the findings of other recent studies (Po-Chedley et al 2015) that reports of weak tropospheric warming have likely been due to flaws in calibration and other problems and that warming patterns have proceeded in the way expected from models. Moreover our data do not show any slowdown of tropical atmospheric warming since 1998/99, an interesting finding that deserves further scrutiny using other datasets.
As with other efforts to homogenize radiosonde data, results here may be affected by sampling limitations and inhomogeneities not successfully removed. However, we argue that our approach is well suited for producing a dataset to examine trends. The approach has been shown (Sherwood 2007) to produce individual data records with larger random errors, but which are unique in avoiding some sources of systematic bias as a feature of the method design, and in avoiding some problems common to other methods that will introduce correlated errors in the trends at neighbouring stations. This feature makes the characterization of trend uncertainty in averages over large regions more reliable.
The data presented here (v2.01) may be freely downloaded from the lead author's website1 The authors hope to produce periodic updates to the dataset in the future, following the same procedure documented here.
