This is why politics and science don't mix...
CO2 is a greenhouse gas, true.
CO2 is a contributor to the temperature of Earth, true.
CO2 will doom us all to a runaway greenhouse effect that destroys the planet, false.
There are a great many gaps between their claims and what we know to be true. Many of them have already been gone over in this thread. They discount or under-represent a great deal of warming caused by solar output, they falsified the temperature record to create our largely mythical industrial temperature rise, and they radically over-represent what is a minor, and already saturated greenhouse gas. It's an agenda, nothing more.
And anyway... Germany is doing fine, it's a rich nation. It shows that one can invest in cleaner energy without ruining the economy (like you seem to think... you're all doom and gloom there).
That's funny. Their idiotic surcharge is primarily affecting industry. Industry takes time to move, it took a couple decades for it to leave the US when the morons over here screwed our corporate tax code and other regulations. Despite powering through the recession, they've been kicking nuclear to the curb for a scant two years and have already taken a beating as a result. .7% growth in 2012 wasn't doing fine, they managed 3% the year before. They exempted a few of their major corporations, so those guys will stick around, but there's a major movement of production happening already. When you add 50% to the amount of taxes being paid as an energy surcharge, it tends to drive them out of the country.
Ten years from now, should they stay the course, Germany will be Greece. The only reason they aren't in a revolt over their green kick is because humanity is too fucking stupid to realize it. They still think it's the recession from 2007 causing them problems, just like our idiots over here can't seem to grasp that it's our commie government piling up ten billion in additional regulation compliance costs every year.
