Global Warming is coming. Are we ready?

As anybody who hasn't been stuck in a cave knows...a part of a freshwater glacier the size of 11,000 football fields broke off days ago. This means that as scientists have been trying to tell us, we are closer to global warming. The fresh water and the salt water have different densities, so that disturbs the Earth's natural air conditioning. If we don't do something within the next 10 years, it is sure we will not be able to fix it. This could lead to an Ice Age and/or a drought that would kill millions of people who don't have the means to adjust to that change. Even small heat waves in other countries kill vast numbers of people. Global Warming is coming, how can we be ready to face it?
