Global Warming???

Question

Could someone please tell me the proof of global warming and the argument against it. Bye the way I have seen an Inconvinient Truth

Answer 1

Frankly, there seems to be a lot of hand waving on both sides. I recently ask the yahoo questions forum for similar facts. It wasn't pretty. For example, when I asked what percentage of GW was natural and what portion was man-made, I got answers ranging from 0 to 90% for man-made. No one had credible sources either way. Many called me names for being 'stupid' enough to need sources.

Probably the best source of data actually is the IPCC Technical reports. Notice that I did NOT say the IPCC Summary for Policy Makers. The "Summary" seems to be more political than scientific. It also seems to pick and choose what data to draw from the technical report. It makes a lot of "interpretations" & "conclusions" that are only loosely linked to the data if at all. I'm not sure this will mean much to you, but the IPCC Summary for Policy Makers seems like it could have been mostly developed ahead of the data. It reminds me a little of those bad physics labs in college where people first drew the curves and then 'collected data' and plotted the points.

The techical report is harder to read but has a lot more hard data. I also suggest going back to the archives and getting the past technical reports as well as the 2007. This probably sounds cynical, but looking at the series of technial reports leaves me with an erie feeling that some of the data could have been tweaked over time in response to objections raised by critics.

The jury is still out regarding my final person opinion, but as you can probably tell, I am beginning to lean slightly in the direction of thinking that a lot of the scare is probably over reaction by many and possibly deception by some. But then again, I tend to be suspicious of politicians. And it is clearly politicians leading the charge. Scientists rarely totally agree on anything. Politicians love to claim that 'all sane scientists support them' and only a few crazies and morons have any doubts left. I'm also inclined to disbelieve whoever is the first to resort to name calling and those who claim that 'the debate is over' on such a major issue.

Answer 2

Wow. Twenty-hours of research makes someone an expert? If the first answer is any indication, you'll not find a satisfying answer in this forum. I'm sorry. This forum has become more and more simply a place where people come with preconceived notions, hoping to find a group of people that will reinforce those notions.

And the idea of all the fossil fuel used daily going up simultaneously in a singular burst of flame when put into perspective is a minute fraction of a percentage of the heat energy received from the Sun each day. So does everybody look up to the Sun and say, "You know what, I think that fire is so big that it's changing the weather over the entire planet." As far as the AGW hypothesis goes, nobody is claiming that the heat energy from fossil fuels is causing the warming, but rather amplification fo CO2 in the Greenhouse Effect.

Answer 3

The proof of Global Warming is simply that thousands of measurements from all over the planet show that we are in a warming trend. That's not really a question that anyone debates. The question is this: Are humans the cause of this warming trend? And in particular, is it our burning of fossil fuels (oil, coal, and natural gas) and the making on concrete that are the root causes of the warming trend? That question does not have an answer with a proof, hence the debate.

My research shows that for oil, humans burn about 35 thousand gallons per second, 24 hours a day, 7 days a week, all year long. So that would be a pretty big fire if we burned it all in one place. And then if we were to add to that the burning of coal and natural gas, it's even bigger. I think that if we saw this roaring blaze, say coming out of a huge volcano, with flames leaping thousands of feet into the sky and the air rushing at gale force winds to feed the fire and the intense heat even at several miles distance, then we might say something like, "You know what, I think that fire is so big that it's changing the weather over the entire planet."

One thing that we know for sure, the fire is getting bigger every year.

Answer 4

Some inconvenient truths;
1) Greenland is called that, because during the
mid-evil warming period, it was.
2) Greenland's ice cap is increasing in depth,
yet melting from the bottom, global
warming is atmospheric.
3) During that same period, Great Briton had a
wine exporting economy.
4) Evidence has been found of grape vines in
Nova Scotia for the same period.
5) The mid-evil warming period is conveniently
"glossed over" by the environmental wackos,
even though it lasted for 3 centuries.
6) There does not exist, scientifically established
minimum or maximum levels of co 2 for any
geographical region.
7) CO 2 is the food for plants.
8) The by-product is Oxygen.
9) The Wackos ignore the most abundant
element which causes global warming, water
vapor.
I wonder why.
10) Science is not a consensus, because a
consensus is a lack of leadership,
it either is, or is not.
Does it make you wonder, when "large al" says that the science is complete one week and the next week another exploration expedition will be launched?

You are aware that if it were possible for man to destroy the planet, there would not be anyone alive to document it?
Do you believe in coincidences?
I don't.
So, would you think it a coincidence that al gore's big push for global warming comes in the year when the earth is closest to the sun?
Its called parihelium, goggle it.
Would you think it a coincidence that al gore owns the co. that sells carbon credits?

Answer 5

The most significant proof of global warming is that the earth MUST HAVE warmed to bring us out of the last ice age. This cycle of warming and cooling has been going on for millions of years.

Answer 6

The only standard of scientific proof is that the scientific community accepts something as proven. There is no "Supreme Court" to decide, and there are always a few skeptics.

Because of the data:

summarized at:

the scientific community accepts man made global warming as proven:

http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_change
http://www.sciencemag.org/cgi/content/full/306/5702/1686

"There's a better scientific consensus on this [climate change] than on any issue I know... Global warming is almost a no-brainer at this point,You really can't find intelligent, quantitative arguments to make it go away."

Dr. Jerry Mahlman, NOAA

There's a wide variety of opinion here because there's a wide variety of knowledge of the data and understanding of science. There's no such wide variety of opinion in the scientific community, just the vast majority and a (very) few noisy skeptics.

Answer 7

And I say this again....

Basically, the belt of ocean currents serves to keep the north atlantic warm (this is why London is much warmer than Calgary, but they are at the same latitude). As the currents warm this area, the overall climate of the earth will increase and the glacier will melt a little. When the glaciers melt, the fresh water flows into the ocean. When enough fresh water flows into the ocean, it shuts down the warming currents and the north atlantic becomes much colder (research the "little ice age" for an example). Now, the glaciers begin to re-freeze due to the climate shift and eventually they will freeze enough to re-start the current and warm the north atlantic region again. This cycle CAN be affected by toxins in the environment, such as the volcanic eruptions that brought about the "year without a summer" and to some extent by air pollution from humans. But to think that we humans can "destroy" our planet or that we can stop the climate from changing is nothing but egoism. We can only destroy our own fragile society. Animals and earlier peoples have adapted to these climate changes and we need to stop worrying about our lightbulbs and learn to adapt as well.

Answer 8

Al Gore pretty much has his facts right, trust me, I just did a 20 hour report on it for my class (jesus christ there is SO MUCH SLANTED BS OUT THERE IT MAKES ME SICK).

He seems to forget to mention that the Ice Age C02 and temperature lag behind one another by several hundered years, he also fails to mentions that any scientist who wants a grant is practically gauranteed it if its about global warming, how the issue is corrupt politically on BOTH SIDES, and the Clarthrate Gun Hypthosis (Methane thats frozen). Pretty much the methane stuff scares the **** outa me (think dinosaur mass extinction, it probably was one of the key factors on that one).

So is there any SET IN STONE proof that humans are causing global warming? NO. The earth is REALLY complicated and temperature risings could be a lot of factors. But I've spent HOURS looking at this and reasearching it, and it comes down to : IT SURE AS HELL LOOKS LIKE ITS OUR FAULT AND GONNA BE A BIGASS PROBLEM.

Trust me. Take my response for what its worth, but I gaurantee you I know more about this than 99% of the people who are going to answer this topic with biased answers.




No, it's not the god damn sun's fault. That statement proves your ignorance. True, solar activity has been responsible for climate changes in the past, but presently C02 trends have surppased that of the effect of solar activity. Read up on this stuff and stick it in your thick skull first. I believe Bob posted some very good websites, and those are all the sites I've looked at. One that's easy to understand is globalwarmingart, which are a multitude of charts from Nasa. It's not hard to see trends....

Answer 9

the waters around florida are quickly riseing and the hurricanes and tornatoes are coming more often and stronger. the reason this happens is the water in the gulf is becoming warmer. this is happening because the antarctica is melting like an ice cube. this is happening because there is a hole in the atmosphere above it. huh. this happens because of global warming and greenhouse gasses.

Answer 10

in case you opt for to get carry of furnish funds for climate study, do you think of which you will get a cheque in case you assert," i choose the availability, as i think of that i'm able to coach that the figures that the present paradigm relies upon are incorrect" ? the great environmentalist, David Bellamy, has been silenced, and refused airtime. there remains no shown causative link between the quantity of Co2 interior the ambience, and an boost in worldwide temperatures. The WWWF pictures of the polar bears swimming have been taken interior the Arctic summer season; whilst the ice cap partly melts, as they could no longer arise to image interior the wintry climate. The ice develop into too thick! The East-Anglian uni study figures. "Oh! The figures do no longer tournament our expectancies. Oh properly. shop quiet. as a results of fact all of us be attentive to that we are appropriate." whilst the perception, and the religion is extra significant than squarely dealing with the valid doubts of numerous non furnish-supported scientists, technological know-how has been superceded via religious zealots. As Oliver Cromwell colourfully stated." I pray thee, interior the bowels of Christ, evaluate that thou mayest be incorrect."
