All coming soon, to a planet near you.

Twenty years ago, June of 1988, Jim Hansen of the Goddard Space Institute presented the first sound data showing human involvement in changing the Earth’s climate. Since then all of his predictions, from temperature rise to melting of the polar ice caps and the glaciers, have come true. With new data, a more comprehensive understanding of the feedback mechanisms and better modeling, he sees much worse to come: sea level rises that will displace hundreds of millions of people, floods and drought on a scope and scale far beyond anything known in human history, extinction of half or more of the species on the planet and collapse of entire ecosystems.

Not to worry, though; we still have twenty years before it all spirals hopelessly out of control.

Maybe.
