Das Klima, ja das Klima ändert sich - endlich bewiesen!

Weil z.Z. wieder mal über den Klimawandel diskutiert wird. Aufsehenerregende Untersuchungen an Eiskernen aus dem Grönlandeis haben vollkommen überraschend ergeben, daß sich in den letzten 4000 Jahren das Klima immer wieder mal hin- und her gewandelt hat. Ach so, wer Diagramme lesen kann, ist voll im Vorteil. Nur mit den Schlußfolgerungen sollte man vorsichtig sein, wenn man nicht ein Sarrazin der Klimatologie werden möchte, wie eben Herr Vahrenholt mit seiner "Kalten Sonne"... (werde es demnächst mal lesen um nachzuschauen, ob wirklich nur Müll drinsteht, wie mancherorts behauptet).

Und hier gehts zur Originalveröffentlichung...

Reconstructed Greenland snow surface temperatures for the past 4000 years and air temperature over the past 170 years (1840–2010) from three records. The thick blue line and blue band represents the reconstructed Greenland temperature and 1s error, respectively (this study). The reconstruction was made by two different methods before and after 1950. The “gas method” is as described in section 2, and the “forward model” is described by Kobashi et al. [2010]. Thick and thin black lines are the inversion‐adjusted reconstructed Summit annual air temperatures and 10‐year moving average temperatures, respectively [Box et al., 2009]. Thin and thick red lines are the inversion adjusted annual and 10‐year moving average AWS temperature records, respectively [Stearns and Weidner, 1991; Shuman et al., 2001; Steffen and Box, 2001; Vaarby‐Laursen, 2010]. (middle) Past 1000 years of Greenland temperature. Thick blue line and band are the same as above. Black and red lines are the Summit [Box et al., 2009] and AWS [Stearns and Weidner, 1991; Shuman et al., 2001; Steffen and Box, 2001; Vaarby‐Laursen, 2010] decadal average temperatures as above. (bottom) Past 4000 years of Greenland temperature. Thick blue line and band are the same as above. Thick green line represents 100‐year moving averages. Black and red lines are the Summit [Box et al., 2009] and AWS [Stearns and Weidner, 1991; Shuman et al., 2001; Steffen and Box, 2001; Vaarby‐Laursen, 2010] decadal average temperature, respectively. Blue and pink rectangles are the periods of 1000–2010 C.E. (Figure 1, middle) and 1840–2010 C.E. (Figure 1, top), respectively. Present temperature is calculated from the inversion adjusted AWS decadal average temperature (2001–2010) as −29.9°C (Figure 1, top). Present temperature and ±2s are illustrated by lines in the plots. Green circles are the current decadal average temperature as above (−29.9°C, 2001–2010).
