My son barely old enough to speak recently asked me, "Dad, what is climate?" You can talk to scientists, you can talk to Al Gore, and other political leaders across the world and none will agree on what climate is. All we know is that climate changes. We know mankind changes the climate at an accelerated pace due to farming and now fossil fuel use. The result, historically, changing rainfall and food harvest patterns as a result of humankind's activity has led to massive migrations, wars and civilizations end. Technology always changes faster than culture can adapt to control the technology that created and then kills them.
