Quoted message said:See, this is the typical attitude regarding global warming. Anyone
that dares raise a question is dismissed as a hairbrained idiot.
Well, not quite. Actually, what we seem to be seeing is the rather messy
argumentation and posturing and politics within the academic community that
is typical of any changeover of a major paradigm. Twenty years ago the
harebrained ones, the ones who couldn't get a hearing, who were castigated
in the relatively rare even that they did... were the scientists worried
about buildup of greenhouse gases and the potential for global warming. They
were the crazies then. Now, as more and more evidence is gathered and
assimilated... and of course as sea levels creep up and polar ice caps
melt... the tables have gradually turned.

As it happens, I was trained and worked for many years as a geologist.
Then it's quite shocking that you refuse to even look at a video, full
of credible scientists, that point out major holes in the global
warming story.
I'm
Quoted message said:aware (and have observed first hand among colleagues) that this is
absolutely typical of how big changes in scientific thinking occur. Well
into a transition there will always be many legitimate scientists who will
fight against the trend, for reasons already given. Mostly because
scientists tend to get very emotionally and intellectually invested in their
own models/paradigms.
All the emotion on this is on one side and that is that global warming
is man made and going to kill us all. I don't see protests in the
street from the other side. I don't see major movies being made.
This is actually a good thing, because the old gaurd's
Quoted message said:arguments will require continued scrutiny and refining of the new paradigm.
One big difference in the case of global warming, however, is that it is...
and was when the consensus was opposite... intensely politicized.
Quoted message said:Did you bother to even watch the excellent video Tunder provided at
the start of this thread? It has 3 scientists from MIT as well as the
university of London, one of the founders of Greenpeace, who all do
not believe global warming is caused by man.
I've only watched part of it so far. But... given my opinion above, you
could probably guess that I wouldn't be impressed too much by some contrary
opinions.
Yes, and it's quite shocking to see how closed minded people can be.
I guess you think it's best citizens just swallow whatever their govts
tell them, without questioning it, or figuring out if it makes sense,
or if there are problems with it. You won't even look at an 75 min
video.
Quoted message said:
Quoted message said:They addressed every major point about global warming that concerned
me and that I have yet to hear any credible explanation for from those
that claim human CO2 is responsible for it.
Unless you're a world class atmospheric-climate expert, I wouldn't take your
opinion too seriously. I probably have a lot more relevant training and
experience than you do, but I really am not equipped to effectively evaluate
the enormous amount of data out there. And I wouldn't expect to find much to
work with in either this or Gore's films, although they are both
interesting.
You know, you could at least watch the God damn video BEFORE shooting
your mouth off. I never claimed to be a world class climate
expert. There are world class experts on the video though. Hmmm, I
wonder if the UN made sure that each and every scientist on their list
of global warming "experts" is world class. Did the dismiss those
that back in the 70s said global cooling was upon us?
Quoted message said:
Bottom line is that there are a few givens any model needs to take into
account.
One, global warming has and is happening.
Two, we've pumped very, very large quantities of greenhouse gases into the
atmosphere in recent decades.
Three, the way these gases work in trapping atmospheric heat is quite well
understood.
The fact that there may be other factors at play doesn't negate the above.
Based on that, it would be difficult how one could argue with any legitimacy
that man has NOT affected earth's temperature.
See, this is where once again, no proof is required and the hysteria
prevails. We've pumped very, very, large quantities of greenhouse
gases into the atmosphere compared to what? All the CO2 from man
when compated to the CO2 that occurs naturally is very small, not very
very large.
Quoted message said:
Quoted message said:Let's take perhaps the
biggest glaring hole. The nice little graph that everyone uses goes
back 600,000 years and shows a line of CO2 cycles and temp cycles.
The cycles fit together quite nicely, so this is a very effective
show. What they never address is, if CO2 is causing the warming,
why does CO2 always start it's up cycle 600-1500 years BEFORE the temp
starts to increase? I heard this exact question asked of one of the
alleged expert professors on global warming. His answer? "That only
means CO2 isn;t responsible for the first 600 years of warming."
Well, firstly the professor's statement would make sense only iif
temperatures start rising well before CO2 starts to increase. Did you get
that backward?
Yes, I did state it backwards. And the fact that you aren't even
aware of this glaring problem with the graph, shows several things:
1 - The inverse relationship from what would be expected is never
cited or discussed when the proponents of global warming present the
graph, so few people are even aware of it. I spotted it myself on the
graphs, because, unlike you, I don't just accept everything, but
instead ask reasonable questions and expect reasonable answers.
2 - You didn't bother to even watch the video.
Also, remember there are a multitude of other factors at
Quoted message said:play, not just CO2 (which, by the way is NOT the only greenhouse gas).
So? The proponents of global warming are telling us that man made
CO2 is the main cause and they are using this graph as one of the main
proofs, without ever explaining how it is that temp rises 600 - 1500
years BEFORE CO2.
Quoted message said:Another thing to keep in mind is that this is probably the only time in
earth's history when something other than natural processes is raising the
concentration of greenhouse gases. And that makes it damned difficult -
risky, even - to accurately interpolate past data onto the present.
OK, so we can't even intrerpolate past data. And that again means it
should be accepted as an article of faith that the rise in CO2 is man
made and going to lead to our demise and that we should take action
that is going to cost people their lives? Yes, that's right, cost
people their lives. Because to switch from fossil fuels is going to
slow world economic growth. And that growth is what has increased
lifespan around the globe and pulled people out of poverty.
Quoted message said:
Just to confuse things...what circumstances tended to result in large,
relatively sudden increases in atmospheric CO2 in the past? One would be a
period of increased volcanic activity (because volcanoes spew out large
amounts of CO2). But the gases are accompanied by a lot of particulates,
which can stay in the atmosphere for years, effectively screening solar
radiation and possibly more than offsetting the greenhouse effect. Or not,
depending on many other factors. On the other hand, CO2 solubility is indeed
enhanced in cold water, so ocean warming caused by tectonic factors or solar
radiation variations would tend to gradually release CO2 to the atmosphere.
I would expect these solubility-temperature effects, however, not to be
super-rapid. As compared to the rather striking effects we've been seeing in
the last few decades. But again, there are more possibly offsetting factors
than you or I could imagine, let alone evaluate. Cause that's how earth and
atmospheric sciences are. Extremely complex.
Well, if it's so complex, how is it that we know for sure what's going
on? The answer is, we don't. In the 70's we had scientists telling
us they understood the same thing, that now they had computer models,
and that we were entering a new mini ice age, due to global cooling.
There were cover stories on Newsweek about it. Plans proposed to try
to intervene to stop it, by trying to shift ocean currents and God
knows what else. Hmm, sound familiar?
Quoted message said:
Quoted message said:Huh? That should bother everyone with even a high school education,
but to the proponents of global warming, no rational explanation is
even required, because, We just KNOW for a fact it must be caused by
man, so this glaring inconsistency should just be ignored.
Not really. You can guaranted that, given enough grant money and scientific
curiosity, these factors will, and probably are now being, evaluated.
Oh, please. The fact that temp rises every time hundreds of years
BEFORE CO2 is such a glaring hole, that only a fool would run around
telling us the world is going to hell without FIRST figuring out how
this could be. Or at least question it. In fact, instead of
investigating it, the alarmists just dismiss it, exactly as you have.
Quoted message said:
Quoted message said:That's
exactly what Al Gore did when he used the graph in his movie.
Please don't confuse popular video offerings with actual science. On either
side of the aisle.
Say what? It's not like Al Gore made up the graphs. If you bother
to open your eyes and look, they are used by all the proponents of
global warming and are available from multiple sources. But
apparently, unlike me, you haven't even looked at these closely.

Quoted message said:On
the other hand, we have scientists who understand ocean science,
explaining that the big reservoir on Earth of CO2 is the oceans. And
as the Earth's temp rises, the ocean slowly warms, so they give up CO2
to the atmosphere, just like a warming bottle of soda. But the oceans
are so deep, it takes hundreds of years for the warming of the Earth
to cause the CO2 to increase, hence CO2 level follows temp. Hmmm,
now who's hairbrained?
That's just one of a myriad of factors. Truth is... we have a large number
of scientists who understand both ocean and atmospheric science, and who
believe that man's activities over the last century have contributed
significantly (though not necessarily exclusively) to the warming that is
now occurring. From what I've seen, that appears to be the consensus these
days, among qualified scientists, though not of course all.
HG
No, it's not the consensus. Again, you could at least take a look at
the video. There are credible scientists on there explaining how if
you disagree with the global warming crowd, you don't get funding, you
get ridiculed and death threats. There are scientists on there who
were part of the UN committee, who submitted work and opinions that
completely disagreed with the whole global warming crowd. Not only
did they leave out their work and opinions, they continued to use
these scientists names on the list of scientists who they said backed
the global warming postition. One even had to threaten legal action
to get his name removed. You call that open debate? Their minds
are about as open as yours. You've bought this whole thing, hook,
line and sinker. And when someone points out a glaring hole,
instead of saying Hmmm? Good question, that doesn't seem right, you
refuse to even thing about it.
And finally, if a "consensus" of scientists is all that is required,
and common folk shouldn't even question obvious holes in the story,
you better give up low carb. Because the overwhelming consensus of
medical and scientific experts say that it's bad and you should eat
low fat. End of story.
