Global warming is real.
It is caused by human activity.
Mankind and its governments must begin immediate action to halt and reverse it.
If we do nothing, in about 10 years the planet may reach a "tipping point" and begin a slide toward destruction of our civilization and most of the other species on this planet.
After that point is reached, it would be too late for any action.
(Ebert, 2006)

Here's where we are...

Here's where we are...

Here's where we're headed...
