Is global warming man-made, a natural event, or both?

Answer 1

Global warming is a natural process, but humans are speeding the process up.

Answer 2

Global warming is natural. The sun has been shining on Earth for over 5 billion years.
I think there is not enough data to determine if man has an effect on global warming. We have been measuring and recording atmospheric temperature for about 100 years. Divide 100 by 5 billion and you get a number so small that it is an insignificant percentage.
In the late 1970's we had record cold and snow in Northwestern Pennsylvania. After a few years of cold, people were predicting the start of another ice age. That was about 25 years ago.

Answer 3

It is scientifically impossible to say that global warming isn't natural. We have only been recording climatological changes for the past 100 years or so. We haven't even had the technology to monitor the ozone layer until very recently. The climate of the world changes in cycles, hence we have had ice ages etc in the past. It is very likely that it is a natural swing in the climate. A cow's farts are has more pollutants than a modern, low emission car.

Answer 4

I feel it's just like "Y2K" a bunch of crap that creates jobs for people. Let's see........all the ice at the caps is going to melt and run the seas over??? Right! Have you ever had all the ice in a glass melt and run the glass over.....NO! It's called displacement. Relax, we will be fine.....Al Gore said that he has been trying to get this message our for "30" years.......Hello!? Haven't seen a great deal of coastal change in the pass 30 years and don't expect to see any in the next several thousand. This old earth has survived quite well over the pass billions of years without all these alarmist preaching death, doom and distruction.
Nuff said...............have a nice day and a better life.
PS: God said that He would never distroy the earth again by water, so relax..............next time it will be fire! Oh, no! Global Warming......getting hotter....hmmm, can fire be far behind? That should get another group of tree huggers on the up rise.
Peace-Out

Answer 5

that's maximum in all threat the two. all and sundry is conscious that greenhouse gases reason the greenhouse results of warming the ambience and so on. And we additionally understand that we are putting a brilliant number of greenhouse gases into the ambience. yet I doubt guy is the only element that impacts it. of direction a brilliant number of animals fart and so on liberating methane (yet another greenhouse gas) into the ambience. And volcanoes spew out greenhouse gases too. Aswell as some flowers contributing. even though quite a greenhouse result's important in any different case we would not be alive via an exceedingly chilly environment. The above reasons for a organic experience have been going on for a while and would not clarify the unexpected upward push, yet there must be yet another organic experience too. The sunlight fluctuates in temperature over a 11-12 year era. before everything of the era the sunlight is less warm than ordinary, and then slowly will become warmer in direction of the top of the era till now without warning starting to be chilly back before everything of the subsequent era. that's via sunlight spots on its floor that reason the sunlight to be cooler. sunlight spots do happen periodically. we are presently on the top of one of those sessions so we are experiencing warmer climes. it is likewise theory that the sunlight has circumstances whilst those sessions are warmer than customary. those larger sessions final for style of one hundred years. The final time it got here approximately replaced into interior the 1500s whilst the Earth replaced into experiencing warmer temperatures than that's now. needless to say polution replaced into no longer playing as huge a factor because it replaced into back then, as a result it replaced into no longer man made. this could be the reason of surprisingly severe temperatures we are experiencing now. even though, what if that's faulty and we are the reason? we are in a place to't be complacent and basically assume that's organic. We ought to act basically in case. playstation the depletion of the ozone layer isn't the greenhouse result as some have been sugesting.

Answer 6

If fluctuations greater than a degree and a half or so were normal, the ice caps/glaciers would have melted long ago, as they continually mixed little by little with fluid water, which then would encroach albeit slowly, but consistently by increasing average land mass temperature in polar regions. So any noticeable reduction in ice volume in those areas would be suspect. Fluctuations below this would cause less noticeable events and trends than are currently being witnessed today.

Answer 7

it is both. warming and cooling of the planet is a natural cycle. there have been several ice ages. gobal warming creates global cooling. humans have just helped to speed up the process.

Answer 8

It is both, think back, ice age, it went away because of global warming. I think man is accelerating it.

Answer 9

Both

Answer 10

It's a little egotistical to think that humans can have any drastic
change to the earth. Volcanoes throw out far more (greenhouse Gas) than humans ever will.
