Proof of global warning

Any proof of global warming in the pic below?

Fun picture. :)

About global warming, yesterday I saw a movie on Greenpeace website.

Apparently (in Britain etc), 2/3 of energy is wasted, and only 1/3 becomes electricity. And the heat from the power plants are wasted by sending them up the atmosphere.

But with a technology (which is in use in Netherlands, Denmark, etc), it would be possible to use that heat to heat up buildings, and it would make the power plants twice as effective.

And it say that oil companies such as Exxon, Esso, etc are the big environment bandits, and that they are funding critics of global warming.
