Global Warming Doubters... Where is your evidence?

Question

Based on the International group of scientists in IPCC, not only is global warming real, but the data shows clearly that humans are to blame.

So, if you doubt this, where is your data? Give me peer-reviewed scientific articles that demonstrate that 1) global warming is not happening and 2) we are not to blame.

Answer 1

"There are about 160,000 glaciers around the world. Most have never been visited or measured by man. The great majority of these glaciers are growing, not melting."

Just to debate the previous posters argument: if the great majority of these glaciers haven't been visited or measured by man, how does he conclude they are growing and not melting?

Frankly, if that bit of rhetorical feces made it into his argument, then I'll take the rest with a grain of salt as well.

EDIT: Furthermore, how does he rationalize his concession that sea levels are rising (and that this is normal) but glaciers are also growing in size? Is all this extra water being created from thin air?

Answer 2

1) There HASN'T been a year hotter than 1998. 2) Perhaps that's not fair since 1998 was an El Nino year. But then, it's equally unfair to compare median income or federal tax revenue to 2000, the peak of Greenspan's biggest money bubble, and most AGW supporters make that comparison in the Politics section. 3) But fine - let's use 2000. Temps have been flat since then. 2008 to date is on the bubble for "top 10 warmest years." 4) 2005 was NOT warmer than 1998. Only GISS concluded that and GISS' average is Northern Hemisphere-biased, thus land-temperature biased.

Answer 3

Go back and look again at what the scientists had to say. In one respect you are being as bad as the doubters that you seem to hold in disdain. The scientists said that we are aiding the problem, but NOT that we are the sole CAUSE of the problem. Please keep your facts in proper order and in level of magnitude.
The same data used to show that we have global warming is similar to data used to demonstrate that global warming ended the last ice age. Given that global warming was the cause of the end of the last ice age, AND man can be the only reason, where is the civilization that caused that warming? Yes, I am using your reasoning against you. If global warming can only be from what man has or is doing to "pollute" the atmosphere, then the end of the last ice age could only be from a civilization that we do not know about, OR a planet full of intestinal gas emitting animals. It would seem that you wish to blame our current use of stored carbon, that is, petroleum and coal, on the trend of global warming. While that may be the part of the answer, I seriously doubt that it is the complete answer. Gasses produced in the intestines of animals, humans included, also aid in the issue. So, what to do, kill off everything that breathes air for life? Lets go to nuclear then. Well that tends to heat things up as well. We can't have that, now can we. How about solar energy. Good idea, but not plentiful enough, nor efficient enough, and there are the costs by heat and gas emissions that cause problems for that as well. I have an excellent answer for the problem, and it could work, everybody just hold your breath, and don't pass gas.

Answer 4

since the big companies are finally waking up i think the people who doubt global warming causes should maybe read a little before opening their mouths.it only takes a second to put your foot in your mouth but it takes a lot longer to get it back out.i know some people cannot admit when they are wrong even when the facts are there they will try to make up something but i think the time for making up a bunch of crap is over and soon the world will change unless the people who believe the causes of global warming and try to change things maybe we cant stop it from happening but maybe we can minimize the affect it has on the world as it is now.noone said it was all are fault they said we are a major contributor to it.open your eyes and see the changes in the world

Answer 5

how about the fact that we are still living in an ice-age? When people say the ice-age ended, what you are basically saying is the last glacial period...we are currently in the interglacial period that started around 10,000 years ago and it is expected to be replaced by a glacial period (according to past climate patterns and not including current co2 trends).

Also, a 90 percent probability in 2007 up from a 66 percent probability in 2001 largely points the finger at humans as being the DOMINANT cause of global warming in relatively recent years

There also seems to be a lack of understanding of the causes of past long-term variations in global temperatures by the naysayers, not taking into account the Earth's orbit around the sun and the tilt of its rotation axis. For example, when the tilt is at its largest, the polar regions receive no solar radiation during winter but during the summer, receive more solar radiation, leading to a all year round higher average than if there were no tilt at all, leading to a retreat in ice-caps.

This also means that if the tilt is smaller, then there would be an increase in the size of the polar ice-caps and a decrease in global mean temperatures. The more the Earth is covered in ice, the more we see a positive feedback loop, meaning, the planetry albedo increases, reflecting more radiation back into space and thus causing a further decrease in global mean temperatures(long-term)

Conversely, if a smaller area of the Earth is covered in ice, the planetry albedo decreases, less radiation is reflected back into space and thus inevitably leads to a warming in the global mean temperatures.

I'm not going to go on and on because people don't like to read lengthy accounts...what I will add though is that there are generally accepted theories that stick as to cause of mass extinctions such as the Late Cretaceous (K-T) that wiped out the dinosaurs and I don't think I need to elaborate any further.

We also have to bear in mind that continental drift, plate tectonics, ocean currents play a part in accounting for past climatic variations....

so, it makes sense then, that in the past 200 years(a very relatively short period), more importantly since the dawn of industry, we have been noticing a year on year increase in the amount of co2 in the atmosphere...taking into account that the natural carbon cycle cannot explain these rises, we then have to look at just how humans have influenced this carbon cycle...and the answer is staring us in the face


edit: good points doom

also (to those mentioning natural cycles)..if your only argument against anthropogenic influence on the current climate is based on past cycles such as ice-ages etc...then you also need to take into account that scientists/climatologists are VERY MUCH aware of these as I mentioned above. Why on earth would they put their careers and reputations on the line if it was that easily refutable? Something to ponder over perhaps?

Answer 6

I don't think there is a scientist that thinks that global warming doesn't exist or that humans are not contributing to the scenario. What is at debate here is, can we stop it? Are humans the sole cause and is this a natural phenomenon? That's the real argument. I see that you have your eyes shut to a differing opinion, once again. Try doing your research and don't ask others to do it for you.

Answer 7

Any change in the earths temp. are related to the sun , ocean and jet stream. Also cows and valcanos. There are inportant things to worry about besides O-zone Als nonsence

Answer 8

I know those "studies" exist somewhere, but they're overwhelmingly funded by the oil companies...check ExxonMobile.com, haha

hey if you start poking holes in those studies post an update

Answer 9

NON-sense, You are ignorant enough to break Yahoo rules, with regards to posting "links", then you are ignorant enough to believe the sky is falling.

Answer 10

Proof?

How about 4.6 billion years vs. 100 years of proof?

Permian Extinction
Mesozoic Hothouse

a few examples
