For your reading pleasure I present

Your quoting a source that once claimed Harry potter lived at the same address as the Prime minister of england. Not exactly the most reliable. it's assertions could be right or wrong. Some of what was written in this post and others is misinformation that I will attempt to correct.
some highlights of the piece are
Between 1940 and 1970, global temperatures went down slightly, even though carbon dioxide levels went up.
Reading a bit farther on this same page will lead you to a sticky concerning sulfuric aerosols released by the biurning of certain fossil fuels like coal and natural gas. Not surprisingly data shows that this global cooldown came right after a sharp increase by tenfold of these items useage especially in Africa and America.
If greenhouse gases were causing the climate warming then scientists would expect the troposphere to be warming faster than the surface, but observations do not bear this out. Satellite temperature measurements show that tropospheric temperatures are increasing with "rates similar to those of the surface temperature,"
The person who wrote that in wiki should be burned at the stake as a heretic...No really. Ok maybe just pummeled. This statement should read tropospheric rates of satellite imagery taken from the tropopause demonstrate a more than 5%dissimilarity between ground troposphere temperature commonly and mistakenly referred to as surface temperature and upper elevation tropospheric temperature." And reading NASA's first paper on this in the ninties you learn that they could not account for the discrepancy. reading the paper written in two thousand shows that they figured it out but couldn't correct the problem because it involved weather balloons, and then their newest paper essentially says that they didn't realize that satellites were just that good. Now they use a combination of several different types of measuring devices to account for temperatures. Did I mention that surface temperature is measured at three different levels? Satellite, weather balloon, and sea level. All of which are measuring the tropospheric temperature.
The problem is that the data on the past is not certain, and the date that is coming in from modern techs like satelite radar mapping, photos, and qualified researchers are ignored by the cry of global warming or the messenger is accused of being funded by "big oil."
I'll agree that old data is uncertain because of poor collection, discrepancies in accounting, and also lack of understanding of some of the physics, but satellite technology, photos and qualified research represent the backbone and an integral part of global atmospheric change research. in fact much of the current debate relates to several thousand global pictures taken as the result of research done concerning global warming trends. These photos show shrinkage of glaciers, desertification, the melting of Canadian carbon sinks, a decrease in fertile lands. Gore's movie was based on primary source material collected by thousands of scientists, all of whom use more modern techniques to study these trends.
as for "Talk to pretty much any climate physicist" please view
http://en.wikipedia.org/wiki/Scientists_opposing_the_mainstream_scientific_assessment_of_global_warming
for their views.
I'm unimpressed by this list. Nearly seventy per cent of this list is retired or emiritus professors who have not touched a research table in nearly twenty years. Most of them don't even have available data and are basing their arguements on conjecture and untested theories. A few of them are dead, one of them, simon from IU his most recent articles suggest he believes Anthropogenic Global Warming exists and effects the planet more than other forms but that that other forms also play a role. he never oncesided with the anti warming group.
a single volcano in a single day puts more CO2 than all of mankind in one year or at least in a month vs the year. so tell me how much are we affecting the CO2 lvls
Completely untrue. http://volcanoes.usgs.gov/Hazards/What/VolGas/volgas.html
That's just fallacious info.
Mars and Venus are also undergoing global warming at a similar rate to ours. We aren't polluting there.
Also untrue.. the only planet with a possibly similar rate is neptune. http://motls.blogspot.com/2006/05/global-warming-on-jupiter.html Although not primary source he does a good job of explaining. Especially about the general temperature difference between us and venus. If we were warming like Venus we'd burn up in a year
80% of temperature sensors in the US used to compute land-based temperature figures are in contaminated locations, such as next to a trash burning barrel or air conditioning unit where the temperature would be artificially higher than normal.
Yeah I hate it when my weather balloon gets caught in my air conditioner. Did I mention that general temperature curves at near surface are measured by ships weather balloons, satellite and specialized thermometers that sit high in the air. Not a very likely spot for AC
The temperature has constantly changed throughout history. Who is to say what temperature is "normal." In fact we're coming out of a mini-ice age now, so the temperature should be rising to some extent.
Very true. Well technically we are still in the mini Ice age from what I understand. of course tempratures have never changed so radically at any time in the past, at least not so fast. Well except when the dinosaurs were all wiped out. Speed of change is very important in this discussion.
A majority of meteorologists do not believe that global warming is man made. Even a few scientists listed on that UN report protested that they do not agree with the report with their name on it.
Actually they disagreed in principle about the weakness of the report. They felt that china was purposefully using political clout to weaken the reports power and therefore protested their names being placed upon what they considered a bubble gum resolution. That was in the news. No one person other than Allegre whose name was on the original report but got it removed because he changed his mind, has disagreed with the idea of GW. Allegre is an interesting problem. he voiced his active change from full support to complete antithesis only after he left the Institute and right when he got his million dollar grant from an oil company. i might be reading into this too much though
I am not someone who fully supports the theory of global warming but I am a trained geologist and chemist with a background in anthropology theatre, geology, chemistry and mathematics. Everything I have said on here is open and all of it can be documented if necessary. I encourage people to continue discussing global warming but encourage them to consider both sides especially when what someone says does not make sense. Not every person who speaks about thias subject is honest, but many of them use data disingenuously. When considering offered info please look for source but if you can't find source documentation look for these main things
1. Pertinence of info.
2. Relation to actual data/relation to data collection
3. Who is making the statement? Chances are if they are not working geologists geophysicicsts etc they may not be up with currecnt science. Which is why anne coulter can never be considered primary source.
4. Timeliness.
5. Corporate or governmental relations
6. Impact in the scientific community. (especially look for repeat offenders who come up with a new junk theory once a week.
7. compare any data listed with available NASA data chances are they either miscalculated or msstated.
8. Never believe any book automatically unless written by jk rowling. Themn you should know it's all real.
