No one can predict whether the earth will be cooler or hotter next year, let alone do anything to change it. If you're afraid of global warming, turn off the lights when you leave the room - but don't participate in the corruption of science, don't scare our kids with unproven cataclysmic theories, and don't try to ban economic energy sources that people living on this planet depend upon today. And don't try to stop progress; it's the only hope the earth has of seeing clean industry, short of exterminating mankind.
In some places, there's the concept of one religion, one truth. In the Muslim world, there's the notion of Allah. The Western, multireligious modern society is some kind of a challenge to this. These, I feel, are the main causes [for terrorism], and, when combined with lots of anger and frustration, cause a huge amount of hate.
