If "Global Warming" is real, what is the reasoning behind the proof and not the theoretical reasoning?

Question

Do not give me theories.
Give me solid facts that is backed up by not only data from 1000's of years but also from hundreds of scientists.

Answer 1

I suggest you read this report: Working Group I Report (WGI): Climate Change 2007: The Physical Science Basis.

I would have included the Summary for Policy Makers to give you a flavor but it is 2.9 MB file all by itself. I think you will find sufficient scientific detail to satisfy your curiosity.

However to whet your appetite I have included a few high lights:

'Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice cores spanning many thousands of years (see Figure SPM.1). The global increases in carbon dioxide concentration are due primarily to fossil fuel use and land use change, while those of methane and nitrous oxide are primarily due to agriculture.

The understanding of anthropogenic warming and cooling influences on climate has improved since the TAR, leading to very high confidence7 that the global average net effect of human activities since 1750 has been one of warming, with a radiative forcing of +1.6 [+0.6 to +2.4] W m–2 (see Figure SPM.2). {2.3., 6.5, 2.9}

Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.

At continental, regional and ocean basin scales, numerous long-term changes in climate have been observed. These include changes in arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones.

Palaeoclimatic information supports the interpretation that the warmth of the last half century is unusual in at least the previous 1,300 years. The last time the polar regions were significantly warmer than present for an extended period (about 125,000 years ago), reductions in polar ice volume led to 4 to 6 m of sea level rise. {6.4, 6.6}

Answer 2

There's a whole mass of evidence but I'll concentrate on just one aspect - not so much why the world is warming but more, how it's warming.

Our atmosphere consists of many different gases. The two primary ones by volume are nirtogen and oxygen. Both these are elements, the gas is made up of atoms. There are many other elemental gases such as argon, htdrogen and helium and these occur in very small quantities.

There are other gases as well that aren't elements - they're molecular. Included in this group are carbon monoxide, carbon dioxide, methane, nitrous oxide and a whole bunch of gases with long names like dichlorodiflouromethane.

Together these atoms and molecules make up our atmosphere, the atoms being tiny and the molecles being large by comparison.

OK, so that's the atmosphere.

Our planet is warmed by heat from the sun, without it the Earth would be a frozen wilderness. This incoming heat is Solar Radiation, it has a very short wavelength. The Earth absorbs much of this heat which it then releases in the form of Thermal Radiation, this has a longer wavelength.

The short wavelengths can easily pass through the gaps between the atoms and molecules in the atmosphere but the longer wavelengths have problems, they're too big to escape easily from our atmosphere.

In simple terms, heat gets in easy enough but has problems getting back out again.

It follows that the more of these large molecular gases there are in the atmosphere the more difficulty thermal radiation is going to have in escaping. These molecular gases are the greenhouse gases and the more we put into the atmosphere the warmer the planet becomes.

This is simple physics, it's been known about for donkeys years and I don't think anyone, not even the most ardent of global warming skeptics, would attempt to deny this is how the atmosphere works.

If our atmosphere didn't have this physical characteristic of being able to trap heat then all the heat from our planet would be lost into space and temperatures would be so cold that life would never have evolved. In this respect at least, global warming is a good thing as it ensures the planet is habitable.

Answer 3

There is not enough proof of anything. Wild weather? No way. Look at the history of weather. It's unpredictable! Evolutionist sceintist said we started life in the water from once extinct fish with limbs and guess what? The fish once thought extinct millions of years ago have been found. Alive! So I think the sceintist more than likely are getting it wrong. I think this "Global Warming" thing is "THE SCAM" of our time. Wake up people start questioning the people and get more in depth answers. Here's a novel idea. Follow the money and see where it leads. We just might see the next "Hoax" for money.

Answer 4

I'm a scientist and I believe in global warming. As far as justifying why, well that's a ploy used by someone trying to win an arguement that is weak. The real reason behind it has a physical basis (reflection of ir light back into the earth's atmosphere). That is proven fact of which thousands upon thousands upon thousands (read millions) of papers are published on. Even so, millions of papers not withstanding, ever eat anything warmed by a heat lamp? That's global warming right there heating your fast food sandwich.

I'm sorry but, anyone who doesn't believe in global warming yet is backing an agenda or is sorrowfully misguided and neither really have any business talking about a physical problem which affects everyone.

Answer 5

Why is it that the only data you get is suspect and all other evidence is anecdotal in nature? What about the original hockey stick which really started the train up about global warming? I don't get to see that much anymore. Where is the data? I look for the data and explanations of how they have arrived at their conclusions, and all I can see are their conclusions or the scenarios laid out, gloom and doom, and doom and gloom.

I am tired of people using there short memories to justify national or global emergencies.
Look at what we are saying to our kids:
In December, when it was unusually warmer in the Northeast, people were saying to their kids or students, "It used to snow in December, now it doesn't, global warming is bad." In the meantime, Denver was snowed in. Then, in January and February, when the cold certainly came in and stayed until April, no one said anything. Now, the next time it is un-seasonably hot, we will tell them, "You're so hot and miserable because we haven't done anything about global warming." To prove their point, they will show an animation of a polar bear drowning in a movie. Wow, what proof that is.

Answer 6

Can't buy the assumption Global Warming is just a way to make headlines, waste taxpayers money, and redistribute wealth. In the 1960's "science" told us that the earth was cooling and we were destined to slide into another ICE AGE in about 10,000 years so much for the infallibility of science. Climate change is a given, but the nonsense hysteria of Global Warming is just that "shrill." But it is making lots of imbeciles lots of money! Think of this Al Gore was a C- journalism student at Harvard who played pool and smoked pot most of the time. Flunked out of Divinity School and law school and NOW he is a leading scientist!!! Gives hope to all dummies in the world, so we got that going for us, which is nice!

Answer 7

The causes attributed to global warming are many and they affect much more than the temperature of the air. The same pollution that is blamed for the warming of the atmosphere is also directly or indirectly related to the poisoning of our water and air, annihilation of thousands of plant and animal species, and human conflicts (ex: auto exhaust is produced from gas that is refined from oil which can come from war-torn countries in the Middle East).

Whether or not global warming is "real" is a mute point. We still must address the same issues to prevent the world from becoming an uninhabitable wasteland.

Answer 8

Global warming is a Democrats myth we only have about 150 year of weather reports and only 100 years of that is accurate. Scientist can say the polar caps are melting could this be mother nature going in it cycle? Remember not long ago Scientist said we'll be soon have a new ice age. The earth is still young planet (as far as planet age) this is just growing pains the world is still evolving.

Answer 9

"Global Warming" more like "Global Waste of Time" there is no evidence past 50 years old for anything on this subject. Everything that is on "Global Warming" is in "Theory" still. Plus it is know that science is not able to "prove" anything, so therefore the proof that are out now are guesses not facts to be used. All of these Lobbyist are trying to brainwash all the world so that they can get more money to develop more efficient energy sources. Supposivly we only have enough petroleum for another 10 to 50 years. This is untrue, what we have 10 to 50 years of oil is easily proccessed oil. In the U.S. there is approximately over 100 years worth of oil in a 100 mile radius. The only problem with it is it is uncheaply proccessed so gas would cost 5 to 6 times what it is now.

Answer 10

It isn't real, there is no proof, and there is no theoretical reasoning. The reason for global warming is to sell tickets to Al Gore's shchlokumentary and to scare people into the Democrat Party.

Answer 11

You people have got to be kidding. The earth cools the earth warms, we learned this in middle school. Ice age no ice age, mini ice age. Mars has warmed exactly the same in the same time period, no humans up there that I know of. Maybe the sun has something to do with climate change? I was always taught that the earth is in a constant state of climate change, either adapt or die. Evolution ring a bell ?
