NASAs James Hansen må have politieskorte på grund af trusler

Nogle af klimaskeptikerne er ved at koge over. NASAs James Hansen fortæller, at NASA i den seneste uge har modtaget over 2500 forespørgsler om muligt fusk med de data, som NASA bruger til at udregne klodens middel (luft)temperatur med.

Han fortæller samtidig, at han her i december måtte have politiets beskyttelse, da han skulle tale ved et arrangement i Houston, Texas. Kort før mødet modtag han konkrete trusler på sit liv. Så ophedede er nogle klimaskeptikere i deres vrede over, hvad de opfatter som en global opvarmningssammensværgelse – og for dem er James Hansen jo hovedarkitekten bag “klima-tsunamien”.

James Hansen reflekterer over situationen i sit seneste nyhedsbrev – og giver samtidig et autoritativt overblik over udviklingen i den globale (luft)middeltemperatur – og de data der ligger bag.

Her er udpluk fra hans brev:

… Fast forward to December 2009, when I gave a talk at the Progressive Forum in Houston Texas. The organizers there felt it necessary that I have a police escort between my hotel and the forum where I spoke.

Days earlier bloggers reported that I was probably the hacker who broke into East Anglia computers and stole e-mails. Their rationale: I was not implicated in any of the pirated e-mails, so I must have eliminated incriminating messages before releasing the hacked emails.

The next day another popular blog concluded that I deserved capital punishment. Web chatter on this topic, including indignation that I was coming to Texas, led to a police escort.

How did we devolve to this state? Any useful lessons? Is there still interesting science in analyses of surface temperature change? Why spend time on it, if other groups are also doing it?

First I describe the current monthly updates of global surface temperature at the Goddard Institute for Space Studies. Then I show graphs illustrating scientific inferences and issues. Finally I respond to questions in the above paragraph.
