A couple points
>"Where's the evidence that German CO2 emissions have increased?"
Google tells me that, among others, the International Energy Agency (IEA) says so. By the way, this article is not only about Germany but also Japan.
>"The author wants to gamble a liveable climate on technology that does not exist"
That seems like an evidence-free claim to me. Might be called a fantasy too, I think.
>"and that has been researched and failed to deliver for at least 50 years."
I quite doubt that the situation is that simple.
