Re: "Disasters to drive public opinion?"
Complete cobblers I'm afraid, in the gentlist possible way. Firstly, Stefan Rahmstorf is an activist, ipso facto, as he is a member of several political organisations such as this one:
http://www.wbgu.de/en/council-members/
An advocay group for global "sustainable development" no less, that uses the climate change narrative as a tool to lobby government and influence policy. Interestingly, even the wiki have this to say about their activism:
" In the most recent flagship report, the WBGU dealt with the transformation to a low-carbon society..."
But ironically Stefan Rahmstorf is no stranger to perpetrating nasty ad hominem attacks himself, and was quite recently found guilty by a German court and ordered to "stop violating a journalists persoanl rights":

Lastly, describing this piece as "uncritical churnalism" is not an ad hominem. Do you know what ad hominem is? Because this is not an example of it.
However, had the journalist who churned and contributed to the information cascade actually researched the Nature Climate Change publication, when it was founded and why, who the primary contributors are... and then perhaps a cursory glance at the recent political activities, advocacy and behaviour of Stefan Rahmstorf himself, they might - whoever they are - have approached the piece from a more enlightened angle.
As I inferred in my original post, I have a higher level of expectation of the Register.
