Rahmstorf In Panic Over Mangini’s Stalagmites

Rahmstorf writes to Overpeck and co-authors:

Dear Peck and IPCC coauthors,

– I know it’s Easter, but I’m having to deal with

    2. Die Daten seien sehr praezise.

    “…Any suggestions what other counter-arguments I could

    So Rahmstorf is only asking for counter-arguments. That’s a nice bias.

    In this video:

    Mangini says just the opposite of Rahmstorf’s claims:

    1. data is global (examples Alps to Norway, Troja, China, Chile) and completely synchronous
    2. data has very good quality
