Who or Whom has proven that their is global warming and who or whom has proven it.? How it was proven ?

Answer 1

The key here is to prove that HUMAN activity contributes to global warming. That will never be proven, it can't be. Here are the factors we would have to take into account to prove that Humans have undoubtably caused global warming.

1. Changes in Solar Activity
2. Natural Changes in the amount of carbon that our Oceans Absorb and Emit
3. The effect of volcanic activity on climate.
4. The effect of water vapor, the chief greenhouse gas, on the environment.
5. The effect of weather systems on global temperatures.
6. The effect of animal emissions on global temperatures.
7. The effect of a cycle of warming and cooling over millions of years that we largely don't understand.

Then we have to use our knowledge of statistics to show that there has been a warming trend caused by man that is statistically significant! and this still subjects us to an statistical error called a type I error.

The fact is no one can prove global warming is significantly affected by man or that it is NOT affected by man, and if they tell you different, they have moved beyond the true science and into the realm of politics.

@3DM below

I have heard of the "wobbling earth" idea before and that it may in fact have a large effect on climate, however I must say I don't know enough about it to give an informed opinion about how large that effect is.

Regardless of whether or not this is a significant factor, which it may well be, it would be another factor to add to our open system of the earth and another variable that we couldn't control or account for.

Remember, SCIENCE is a controlled experiment that can give repeatable results, a POLL is a consensus of scientists that gives an opinion.

Answer 2

I guess the answer would depend on where you drew the line between proof and speculation.

A) The school I went to back in the early 70's has a temperature record taken by 5 and 6 year old kids that stretches back over 50 years, this in itself very clearly shows a rising temperature.

B) 2500 of the worlds leading experts working in the fields climate and related disciplines have spent years collating evidence and conduction research.

To some people a bunch of school kids and a thermometer provides all the proof they need, to others the evidence from the world's leading experts isn't enough.

If you wanted to put a name to it then probably Svante Arhennius would be the person to go for. He was a Swedish chemist and in 1896 extablished the links between greenhouse gas emissions, the greenhouse effect and global warming.

As to how it was proven - that's easier to answer. It's a physical property of the greenhouse gases that they trap heat within the earth's atmosphere. This is comparatively easy to quantify and as such can be proven by pretty much anybody who sets their mind to it.

To Nickolassc - the 7 numbered points you mentioned are all taken into account as is the 'wobbling earth'. I won't go into detail here but you may wish to post a question, if I see it I'll answer it.

Answer 3

No one can ''prove'' anything of the kind.There may be a warming going on. Over time it will be followed by a cooling, which in turn will be followed by yet another warming and so on. There is nothing to panic about. The world as we know it will not end. We are not all going to perish as a result of this warming trend. Just about everything we understand to date has a pattern. This wave pattern occurs often in nature, including ocean waves, sound waves, and light waves.All of these can be graphed or illustrated with a sine wave, and as a result can then be monitored and analyzed. In the case of global temperature we just don't have enough accurate data yet to ''plot'' a pattern which would help us predict coming changes. Don't forget, the only accurate recorded data we have dates back only about 100 years, everything else is just theories and guesswork.People blindly follow the liberal's media hype about ''man creating global warming through his abuse of the Earth and it's resources'' and how ''cities will become submerged and we will all perish''. They are always saying that the earth is warming up and they cite data from millions of years but in reality we only have about a hundred years or so of accurate data, the rest is all theory (guesswork).. In fact it is probably just part of a cycle. I would imagine if we had realistic meteorological data from more than just a hundred years we would see a pattern (or frequency), not unlike sound and light waves form.

Most of it is just the liberal's media stirring things up. For example, if the polar ice caps are melting the why after only forty years in the Arctic did they find a squadron of air planes 250 feet below ice?

Answer 4

I like your summary, nickolassc, but I'm wondering if there is one factor that could be contributing to a warming trend that has been getting little media attention, and that is the cyclic fluctuations in the Earth's orbit, precessional tilt and wobble, fluctuations that have been largely responsible for ice ages and warming periods over the history of the planet.

Does anybody out there know exactly where we are in this set of cycles? (There are a number of them, each with a differing period.) Is there a possibility that there is a fluctuation that has not been measured - one whose period is so much longer than man's history of studying astrophysics that we have not picked up on it, yet?

Alarmists like to say that the fluctuations of solar output are not large enough to produce the current amount of global warming, but these Milankovitch cycles do have the effect of increasing solar forcing to one hemisphere of the globe. For example, the Southern hemisphere currently experiences Summer when closest to the Sun, winter when farthest. The net effect is greater seasonal extremes. On the other hand, this is flipped for the Northern hemisphere meaning more Sun exposure in Winter, less in Summer - decreasing extremes. But the two hemispheres are not independent climate systems. Global ocean currents and atmospheric winds produce a dynamic interaction, such that global climate cannot be reduced to a simple "mean temperature rise" as the singular indicator of it's well-being.

Just wondering...

Answer 5

Global Warming may not be proven but it sure has alot of information that suggests THERE IS A PROBLEM. Whether you want to call it global warming or something else, how can somebody argue that the Ozone, forest destruction, increasing human populations, ice shelves melting, animal populations decreasing (or being wiped out), pollution from factories and cars, and so on are not problems? I don't see how people can say that all this is natural. The Ozone alone can tell you that many of these problems are caused by humans.
Did you know that ONE CFC can kill/destroy 15,000 0*2 molecules? And each of these molecules take 100 years to regenerate and reach the stratosphere whereas the CFC's only take 15 years to reach the stratosphere? And problems with the Ozone can lead to many problems from lung and respiratory issues to more severe problems from the sun's radiation.
The Ozone is only one example of the problems this planet is facing and is due to humans (everyone not just democrats or republicans but everyone). There may not be proof of Global Warming, but there is alot of information that can conclude that there is a man-made problem with the planet.

Answer 6

The proof is in the peer reviewed scientific literature, published in scientific journals. The problem with the discussion here is that very few here have actually looked at that scientific literature.

For example, these are good summaries of the proof, but they are only summaries. The proof itself is in the scientific articles listed as references.

http://www.ipcc.ch/SPM2feb07.pdf

It's not practical to post a short proof here. It would be like saying "Prove relativity in a few paragraphs on Yahoo answers". The 2nd summary above is 21 pages long, with many graphs. It is just a summary. The final report is expected to be about 2000 pages long.

So, those of us who know it has been proved point to the scientific community because they HAVE read the articles. And the scientific community has accepted that global warming is real and mostly caused by us.

http://en.wikipedia.org/wiki/Scientific_opinion_on_climate_change

There is no one person who has proved it. The proof is the accumulated efforts of thousands of climatologists over the past 20 or so years.

This is a field of study, not a sound bite.

Answer 7

both of the above statements are accurate. based on actual measurements taken, the earth's mean air temp has increased by a little less than one degree F over the last hundred years. that's not very much, and falls within the definition of 'noise', i.e. it's not a statistically significant difference. ocean temps are up by about 1/2 of one degree and the effect, if any, can't be measured. It's easy to produce dramatic footage of glacial ice falling into the sea, but less easy to show that in some areas (Norway, Antarctica) the glaciers are growing, and surely less dramatic.
Even if it turns out to be true that we are warming the planet, what can you do about it? stop breathing?

Answer 8

THERE IS NONE

Simply because we have no model of our earth and we can't make one thats exactly the same

i dont believe in it no one should

but i do believe at the same time we need to pollute less and save the our planet

AND even if its just a "little" thing like turning off a light bulb if tons u ppl did these "little" things it would make a huge impact
