How much global warming do you think is caused by man?

Question

Me personally, i think about 5-7%

Answer 1

Scorbore, wise son of Adam, you may be correct. But you need to look at global warming in a different way. Picture it as a huge boulder at the top of a hill. It takes but a small percentage of force to push the boulder from the top, as compared to the force the boulder will generate on its trip downhill.
The small percentage humankind added to global warming started a cycle that can no longer be controlled. Many generations of humankind will now have to deal with the effects.

Will the effects be as dire as most predict? Who knows. But lets not push anymore boulders down the hill.

Answer 2

0%

the earth has processes that go on that we dont even know about. Warming and cooling is a predictable pattern, based largely on the earths elliptical orbit around the sun. Bringing it further from the sun and closer to the sun during different periods. If it is a man made phenomenon, then how did the glaciers melt after the last ice age? and all the previous ice ages? Were the cavemen driving SUVs? were there other industrial revolutions that we have forgotten about? or is it a regular pattern of warming and cooling? cows belching this year causes 30 times the greenhouse gas emissions than all humans since the industrial revolution. The Earth will be here when we die, it always will, it does as it pleases. We are here for the ride, and there is nothing we can do about it

Answer 3

I don't know. My honest guess, about a quarter. The theory is a CO2 blanket in the troposphere. Stratospheric cooling indicates that this is happening, but the stratosphere started cooling at about the same time that Oban made the scotch I'm going to drink tonight. That accounts for about 0.4 degrees F of the warming. Even if you give them all of that that's 1/3 of the warming since 1880, at the end of the Little Ice Age. Most warming periods have been about 150 years of warming followed by a few centuries of warmth - thus the natural warming was unlikely to have ended in the late 1980s, so some of the warming since then was probably natural.

Answer 4

I think your estimates are a little low. Scientists have already agreed that much of global warming is a natural trend in climate change, that has occured in the past and will occur in the future. That's not what is being debated. What is being debated is the RATE at which this climate change is occuring, whether it is this rate change that is caused by man, and whether this rate change could destabilize the natural cycle of climate change irreversably. The consensus is, YES! That the rate of climate change is largely caused by man, and could destabilize the earth 's natural climate cycle causing it never to be able to recover...see: MARS. (the most agreed upon numbers are: 30% of earths "global warming" or greenhouse emissions are caused by natural biological/geological processes not to include mass animal farming. The rest of the acceleration..you got it..manmade.)

Answer 5

The consequences of Global warming are bad enough that it don't matter if it is 1% something as a matter of fact everything that could be done should be. I am lucky, I will die before anything real bad happens because of it, but the kids, maybe, the grand kids maybe more and so forth will feel the effects of it if we do not do something. I am not sure we can even reverse it at this point but we should try.

Answer 6

I do not believe that man has or will have a significant affect on the planet's overall weather patterns. Most of the biggest volcanos generate more CO2 gas than all of man. This planet has been through multiple ice ages and is coming out of a small ice age. Global warming is natural and will continue until the temperature rises to a point in which it causes a reversal. This pattern will continue for the life of the planet.

Answer 7

I don't know the percentage, but, however much it is, it is obviously enough to tip the balance of global warming to a hazardous level for all living things. There cannot be billions of humans with, gluttonous consumption appetites, praying on the natural resources, spewing toxic emissions, without consequences. As has been said: " you pay me now or you pay me more later". Earth.

Answer 8

With as much pollution as mankind is generating I think it is naive to think we are not having any effect. How much exactly is unknown but if the threat of global warming pushes us to develop alternative forms of clean energy than so be it.
We can't abuse the environment forever and think we are not having any effect on the planet.

Answer 9

subcrete.... look at the archaeological evidence of PAST warming events.... they have happened numerous times, in faster timeframes even, and to even more extremes.... the warming event of the dark ages was fast and to a MUCH higher degree that what we have been experiencing now.....

It is hard to say how much impact we as humans have on this.... but we do not have even remotely close, the power of influence for this like the Sun, the internal core of the earth (eruptions, etc), or the various other NATURAL causes to these cycles of global warming and cooling....

IMHO to say that we are causing 60+% is asinine and is fed by the enviro-nazi whack-jobs

Answer 10

ZERO!

Global Warming is a farce... much like the Y2K scare of the late 90's.

In fact, the liberals are now calling it "Global Climate Change" due to to all of the record low temperatures the world has been experiencing this year.
