Has it been proven that the emission of carbon leads to climate change or is that just the most likely contributor?

No scientist here, but I understand that "global warming" is a proven fact, and is a natural occurence. I think the answer to your questions is, "more likely than not." To me that's like saying, if you jump off the Brookyn Bridge, more likely than not, you'll get wet.
I think the problem is because we have artificially accelerated global warming to an extreme degree.
Climate change is real, and natural. But not at the extreme degree at which it is now occuring. Since scientists have been recording this information, the rate at which changes have been happening has dramatically increased within the last century. Our climate is changing (warming) at a rate never before recorded.
For instance: During the 20th Century sea levels rose by .067 inches; since 1993 alone, sea levels have risen by .118 inches PER YEAR.
Eleven of the twelve hottest years so far recorded have taken place since 1995.
Since 1900, the earth's surface temperature has risen over 33.3 d F.
Virtually all of these occurences are caused by human activities: deforestation, burning of fossil fuels, release of excess carbon into the air.
I understand that the general not-for-profit scientific consensus is, that we cannot stop it, but we may be able to change or mitigate its end results.
That alone, is worth trying to live green, if we can.
There are some people who actually believe that this is all "socialist" bunk. And if we can't see the effects in our own back yards, it's not happening at all. Their ancestors probably believed the world was flat, too.
