Abstract:

Monthly instrumental temperature records from 5 stations in the northern hemisphere are analyzed, each of which is local and well over 200 years in length, as well as two reconstructed long-range yearly records - from a stalagmite and from tree rings that are about 2000 years long. In the instrumental records, the steepest 100-year temperature fall happened in the 19th century and the steepest rise in the 20th century, both events being of about the same magnitude. Evaluation by the de- trended fluctuation analysis (DFA) yield Hurst exponents that are in good agreement with the literature. DFA, Monte Carlo simulations, and synthetic records reveal that both 100-year events have too small probabilities to be natural fluctuations and,...

Abstract:

We evaluate to what extent the temperature rise in the past 100 years was a trend or a natural fluctuation and analyze 2249 world- wide monthly temperature records from GISS (NASA) with the 100-year period covering 1906-2005 and the two 50-year periods from 1906 to 1955 and 1956 to 2005. No global records are applied. The data document a strong urban heat island effect (UHI) and a warming with increasing station elevation. For the period 1906-2005, we evaluate a global warm- ing of 0.58 0C as the mean for all records.

Widerlegt die Arbeit von Kramm und Dlugi den Treibhauseffekt des anthropogenen CO2?

Von: Dr. Link, Prof. Dr. Lüdecke

Eine Klimasensitivität des CO2 von grob 1 °C – ohne Rück- oder Gegenkoppelungen – ist Konsens so gut wie aller Klimaforscher weltweit, ob sie nun die AGW-Hypothese des IPCC ablehnen oder ihr zustimmen. Es ist ein unbedenklicher und vernachlässigbarer Temperaturwert, der mit den spektralen Labormessungen des CO2 sowie der elementaren Atmosphärenphysik bestens in Einklang steht und erst nach Verbrennen aller fossilen Brennstoffreserven erreicht werden kann - wozu es aber wohl kaum kommen wird.
