Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.

Global warming is actually a misnomer. It should be global extremes and global swings, because you add - as you add more energy into the atmosphere, it sloshes around. Energy doesn't simply uniformly warm up the planet. And that means droughts in one area, enormous snowstorms in another area, 100-year floods here, 100-year forest fires there.

Global warming isn't a prediction. It is happening.

How lazy are we getting?! Just throw it in the recycling bin already!

I'd say the chances are about 50-50 that humanity will be extinct or nearly extinct within 50 years. Weapons of mass destruction, disease, I mean this global warming is scaring the living daylights out of me.
