Some things are well accepted about it. The Earth's average temperature has risen slightly over a half degree Celsius over the past 100 years. Humans have had an impact on this. Some activities that humans do make the Earth warmer, and some activities we do make the Earth cooler. But the Earth also goes through colder and warmer periods on its own, without human intervention. Mainly what people debate is how much of an effect human activity has had on the rise in temperature vs. how much the temperature would be changing on its own regardless of human intervention.
AH ha, I see. So there is
a correct answer as to whether or not, say, carbon dioxide and methane contribute to global warming - and that anwer is a yes, and there is no other correct answer.
But what is debatable is the extent to which human activity has caused global warming.
as far as the other comment,
, ya I think the same thing about science. I think "thank GOD there are people out there that actually get this stuff and are good at it cuz it aint gonna be me!"
I felt so dumb in science class! I actually thought I had a learning disability in grades 9 and 10 because I would kick ass in most other subjects except science (and to a lesser extent, geography).
So two important things to know about CG:
An unscientific mind and a body that hates back workouts.
