Some people believe that global warming is just the conspiracy to control the development of industrial country. Sometime, I think so. What about you?
Scientists worldwide agree that global warming is happening, and that human activity causes it...
No they do not.
They typically may say something like human activity is a partial factor.
It depends on semantics....
No, none of that double talk is necessary at all.
Human activity is simply one dimension affecting climate, and within that, there are regional issues such as the "brown cloud" over Asia, farming techniques, deforestation, and then in one corner a group of issues concerning co2.
Of course politicians latch on these to attempt to exert control. So yes, conspiracies certainly exist.
