Opposing Views

Ok, I admit, some of these things seem more like conspiracy theories than actual fact, but it is interesting to see their point of view and see if there is anything to this...

First off, Global Warming or Climate Change?

Next, 9/11, unanswered questions?

Then, Constitutional Integrity, where is the Birth Certificate?

I am just more interested in opinions of others about these issues, I am not spouting or supporting these as "gospel truth", just that they have an opposing view, one that may or may not have merit.
