TerraMadreFoundation asks:Are humans really to blame for global warming?

that it depends on who you ask. Certainly man has had a big impct on the world around him, and has hastened the demise of some species.. I also think though that the Earth goes through these cycles and every now and then gives itself a shake and turns things upside down. Is the earth warming up, and heading into a new ice age hundreds of thousands of years from now? Yes... is i ALL our fault? No, i don't think so.

...And if someone came up with "what amount of percent", what would it prove? That question is a distraction, means nothing at all.

need to have a number though heretoday... it makes it easier to understand when they can put a label on something that says.. 'it's THIS bad' I agree it is a meaningless number though!

If people need to have a number, then shouldn't they be the ones to do the studying to find what the number might be?
I think that the time for explaining why we are environmentalists has come and gone (thank God), and the people who are NOT environmentalists have some explaining to do.

I don't think that anybody really knows how much of a percent that humans contribute to global warming. I think that that's impossible to know for sure.
