Would GLOBAL WARMING still happen, if Earth was absent of human life?

Question

Careful with your answers. Although not a trick question, do some research first before you answer, else those with common sense will thumbs down your response.

Answer 1

It happened when human life wasn't on the planet but it didn't happen as much.  Now that CO2 levels have risen Global Warming has become more serious but there was CO2 emissions even when we weren't on the planet but not as bad.

Answer 2

yes, stop with the games here.

Answer 3

Does it really matter?  I know some people are advocating reducing the population and feel like Man is a parasite on this planet. If something is not done about Al Gore and this movement, we are all going to be taxed too death.  

Answer 4

No. it is impossible for the earth to have any change. it wasn't until humans came to the earth 400 years ago aboard the cenortain cruiser from epolix constellation that the earth had any change. they were smart and developed fake civilizations to fool us into thinking we've been here longer, but careful analysis of betacaronine composition of rock formations in souther italy clearly indicate civilizations do no appear to be older than 258 years old.  

Answer 5

It did before, didn't it?

Answer 6

Climatoligists had a big meeting in Australia last year, IIRC, and determined that over the next century the temperature would rise 3 degrees, and that without the human contribution, it would rise only two degrees.  Humans were responsible for 1 degree in their opinion.  The UN politicians then decided that wasn't good enough, ad had their own investigation, in which they determined humans would be responsible for two degrees of warming, because it is hard to claim the government should control every detail of your life if humans are only contributing one degree.  

We would definitely have global warming with or without humans. But we would not have global warming hysteria.  If a tree falls in the forest, does it make a noise?  

Answer 7

Yes, definitely, but there is a great deal of evidence that a) it would happen more slowly and b) we can help slow it.  

Answer 8

"It was cooling slightly from 8,000 years ago until about 100 years ago."

Yeah, but this whole theory is based on man-made CO2 and temperature correlation starting from about the 1970's. From 1900-1940 (approx) the globe was warming and human CO2 emissions were negligible, then from the end of WWII to about the mid 70's the earth was cooling while CO2 by humans skyrocketed. Now, this theory is based off of computer models which don't fully understand all the dynamics of global climate and about a 30 year correlation. So, I think the earth would probably be seeing the same climate change with or without us.

EDIT: If you're going to attribute the recent warming to man-made CO2, then what caused the warming in the early 1900's, or the medieval warming period?

Answer 9

Generally speaking, yes.  There are of course natural climate changes, both warming and cooling.

Right now, no.  If not for humans, the planet would be experiencing no significant temperature change right now.  It was cooling slightly from 8,000 years ago until about 100 years ago.

Answer 10

global warming and global cooling is a part of climate change, which occurs as a result of the sun's energy being slightly more or less, has nothing to do with human activity-only the idiotic believe otherwise, and by the way, I do not care if i get 'thumbs', either way, it doesn't change reality.

Answer 11

global warming is entirely b`coz of us. natural process like volcano, lightning etc works in a different way, more precisely in a natural way. there is always some compensatory mechanism working.  we  are putting more garbage than the mother earth can clear up.

Answer 12

No, because it isn't happening anyways.  Too much hype over it.

Answer 13

Yes, because there is no evidence that man is the cause of global warming,

Answer 14

yeah - man is just making it happen faster - so fast we cant adapt to it - thats why its a bad thing - if it was naturally happening we would adapt over years - so we would kinda evolve into animals which can survive on a hotter planet....

Answer 15

Absolutely, this one graph tells it all.

Answer 16

Global Warming, Global cooling, Global climate change. Sorry, but I'm to confused to answer your question!

Answer 17

No we are on par with a 450,000yr average. What's the problem?

Answer 18

Dana's right. It's so sad that people thumbs-down legitimate and correct answers just because they're too prejudiced to realize the answers are correct.

Yes, global warming and global cooling happen naturally.

However, if there were no humans, we would be seeing cooling now instead of warming. Global warming is happening now and it is caused by humans. There is no legitimate scientific debate.
