Yup, we've known about climate change for years. Why haven't we done anything about it? Because there is no conclusive evidence that humans are causing it; all the evidence points to it being a completely natural occurrence.
Forget about political conspiracies as well; the scientific community have been arguing over this for years. Depending on who you ask, the Earth is either out of an Ice Age, or still in one. Depending on which, that means the temperature should be staying the same, or rising. Since it is rising, and ice core samples show this has happened before, I'm sticking with the theory that we're still in an Ice Age, and coming out of it.
