Instead of attempting to slander his character & criticize his taste in films, as well as what you assume to be his personal beliefs, why don't you
try pointing out where he is incorrect?
Jeez, do I have to? It would be like shooting fish in a barrel...
I don't claim to be an expert on climate or meteorology, but I have done my share of research, and he seems quite factual & rational to
me.
I'm sure he does.
If it's all pseudoscience then why don't you point out to us where he is in error.
Enlighten us! I for one would be interested in hearing a rebuttal.
I might edit this in a minute. I'll probably just link elsewhere, as it's late, the dude's an eejit and not worth much of my time.
ABE:
Lets go from the start:
This is a stupid comment:
First, the expression "climate change" itself is a redundancy, and contains a lie. Climate has always changed, and always will.
So what? The issue is the modern era of climate change, it requires a label and 'global warming' and 'climate change' are as good as any. It's no
lie. It contains no suggestion that climate is ever truly stable, just a focus on this modern period of climate change.
Mr. Gore has used a famously inaccurate graph, known as the "Mann Hockey Stick," created by the scientist Michael Mann, showing that the modern
rise in temperatures is unprecedented, and that the dramatic changes in climate just described did not take place. They did.
This is total BS and is like denier's tourettes. As soon as I see this rotten canard make an appearance, I know the source is a crank. There are a
dozen other studies that show exactly what the original Mann et al study demonstrated. Inaccurate? I doubt Mann's study was perfect, no studies are,
and it was the very first large scale proxy study. Here's a dozen more recent studies showing climate over the last 1000 years or so in the northern
hemisphere:
Of course, if he looked beyond all the BS spread about the denier's echo chamber, he'd know about them.
One last thought on the expression "climate change": It is a retreat from the earlier expression used by alarmists, "manmade global warming,"
which was more easily debunked. There are people in Mr. Gore's camp who now use instances of cold temperatures to prove the existence of "climate
change," which is absurd, obscene, even.
This is tripe. 'Global warming' and 'climate change' have tended to be used interchangeably. 'Climate change' has been used for almost 30 years,
it's in an early NAS report and the IP
CC has been around for about 20.
In fact, the one instance I've seen of people preferring 'climate change' over 'global warming' for propoganda/framing purposes is in a
republican funded report (See the Luntz memo). It was suggested that 'climate change' should be preferred as it was less likely to scare the
plebs.
Climate change is just a better term, as it covers the whole issue better than just 'warming'. I'm not sure on the last sentence, I've never seen
anyone of interest suggest that transient cold temperature is indicative of climate change. Indeed, using transient instances of weather for arguments
at a level of climate appears to be a favourite of his (see his blog website - oh noes, it's snowing in Las Vegas, lol), just as much as it is for
the likes of his pet hate, Gore.
Indeed, it is Mr. Gore and his brethren who are flat-Earthers. Mr. Gore states, ad nauseum, that carbon dioxide rules climate in frightening and
unpredictable, and new, ways. When he shows the hockey stick graph of temperature and plots it against reconstructed C02 levels in An Inconvenient
Truth, he says that the two clearly have an obvious correlation.
They do. Indeed, the idea of CO2 as a GHG is based on very basic physics which has been known about for over 100 years. Flat earther indeed.
The word "complicated" here is among the most significant Mr. Gore has uttered on the subject of climate and is, at best, a deliberate act of
obfuscation. Why? Because it turns out that there is an 800-year lag between temperature and carbon dioxide, unlike the sense conveyed by Mr. Gore's
graph. You are probably wondering by now -- and if you are not, you should be -- which rises first, carbon dioxide or temperature. The answer?
Temperature. In every case, the ice-core data shows that temperature rises precede rises in carbon dioxide by, on average, 800 years.
Heh, the lag issue - so predictable. This was actually expected and does nothing to suggest that CO2 does not force warming. We don't expect CO2 to
just enter the system magically, lol.
In fact, the relationship is not "complicated." When the ocean-atmosphere system warms, the oceans discharge vast quantities of carbon dioxide
in a process known as de-gassing. For this reason, warm and cold years show up on the Mauna Loa C02 measurements even in the short term. For instance,
the post-Pinatubo-eruption year of 1993 shows the lowest C02 increase since measurements have been kept. When did the highest C02 increase take place?
During the super El Niño year of 1998.
So he loves the egg but ignores the chicken. Of course warmer oceans tend to release CO2, that's as much basic physics as CO2 being a GHG.
CO2 is both chicken and egg.
What the alarmists now state is that past episodes of warming were not caused by C02 but amplified by it, which is debatable, for many reasons,
but, more important, is a far cry from the version of events sold to the public by Mr. Gore.
He appears to be saying that CO2 was a feedback in the past, but says it's debatable that it resulted in warming, lol. Eejit.
CO2 is a GHG, of course is causes warming.
Meanwhile, the theory that carbon dioxide "drives" climate in any meaningful way is simply wrong and, again, evidence of a "flat-Earth"
mentality. Carbon dioxide cannot absorb an unlimited amount of infrared radiation. Why not? Because it only absorbs heat along limited bandwidths, and
is already absorbing just about everything it can.
That is BS. Where is he getting this tripe?
That is why plotted on a graph, C02's ability to capture heat follows a logarithmic curve. We are already very near the maximum absorption level.
Further, the IPCC Fourth Assessment, like all the ones before it, is based on computer models that presume a positive feedback of atmospheric warming
via increased water vapor.
BS. He's just making this stuff up. CO2 is nowhere near it's saturation level. He is right it's logarithmic, though. Hence, climate sensitivity is
assessed in doublings of CO2 (2x CO2 = 3'C, 4x CO2 = 3'C, 8x CO2 = 3'C). Pity he has to spoil it.
Lots of room for absorption even at 4x CO2
Indeed, even at 10000x CO2 saturation wouldn't be achieved.
More here.
Further, the IPCC Fourth Assessment, like all the ones before it, is based on computer models that presume a positive feedback of atmospheric
warming via increased water vapor.
Yes, it makes sense and has been confirmed. Water vapour is also a GHG and a strong feedback.
This mechanism has never been shown to exist. Indeed, increased temperature leads to increased evaporation of the oceans, which leads to increased
cloud cover (one cooling effect) and increased precipitation (a bigger cooling effect). Within certain bounds, in other words, the ocean-atmosphere
system has a very effective self-regulating tendency.
What! The effect of variations in water vapour on temps has never been shown, lol.
I would suggest he look up Andrew Dessler's work, that of Santer et al., (2007) and Soden et al (2001). For example, Dessler et al (2008):
Water-vapor climate feedback inferred from climate fluctuations, 2003–2008

Between 2003 and 2008, the global-average surface temperature of the Earth varied by 0.6°C. We analyze here the response of tropospheric water vapor
to these variations. Height-resolved measurements of specific humidity (q) and relative humidity (RH) are obtained from NASA's satellite-borne
Atmospheric Infrared Sounder (AIRS). Over most of the troposphere, q increased with increasing global-average surface temperature, although some
regions showed the opposite response. RH increased in some regions and decreased in others, with the global average remaining nearly constant at most
altitudes. The water-vapor feedback implied by these observations is strongly positive, with an average magnitude of λ q = 2.04 W/m2/K, similar to
that simulated by climate models. The magnitude is similar to that obtained if the atmosphere maintained constant RH everywhere.

Observations confirm models.

Data from the satellite-based Special Sensor Microwave Imager
(SSM/I) show that the total atmospheric moisture content over
oceans has increased by 0.41 kg/m2 per decade since 1988. Results
from current climate models indicate that water vapor increases of
this magnitude cannot be explained by climate noise alone. In a
formal detection and attribution analysis using the pooled results
from 22 different climate models, the simulated ‘‘fingerprint’’
pattern of anthropogenically caused changes in water vapor is
identifiable with high statistical confidence in the SSM/I data.
Experiments in which forcing factors are varied individually suggest
that this fingerprint ‘‘match’’ is primarily due to humancaused
increases in greenhouse gases and not to solar forcing or
recovery from the eruption of Mount Pinatubo. Our findings
provide preliminary evidence of an emerging anthropogenic signal
in the moisture content of earth’s atmosphere.
That's all for now, he's too easy. Suppose I could carry on if you need me too...
