Claims of more intense cyclones/hurricanes from AGW take another blow

Tropical Cyclone Intensity Discrepancies (16 Nov 2010)



The claim that 'man-made' global warming leads to more intense tropical cyclones and hurricanes takes another blow...



According to the NIPCC, "In light of the findings of Song et al., plus those of the other scientists they cite, there would appear to be little doubt that the studies of Emanuel (2005) and Webster et al. (2005) - which climate alarmists long hailed as proof positive of their claim that global warming leads to more intense tropical cyclones/hurricanes - actually provide no such evidence at all."...

Real-World Increase in Air’s CO2 Content Has Accelerated Growth of Natural Aspen Stands (16 Nov 2010)



Young trees grew faster in recent years than did young trees several decades ago such that “the effect of rising CO2 [was] to increase ring width by about 53%,” as a result of “a 19.2% increase in ambient CO2 levels during the growing season, from 315.8 ppm in 1958 (when CO2 records began) to 376.4 ppm in 2003.” ...

ENSO Activity and Climate Change (17 Nov 2010)



The finding of “similar century-scale variability in climate archives from two El Niño-sensitive regions on opposite sides of the tropical Pacific strongly suggests that they are dominated by the low-frequency variability of ENSO-related changes in the mean state of the surface ocean in [the] equatorial Pacific.” And that “century-scale variability,” as the authors of this paper describe it, suggests that global warming typically tends to retard El Nino activity, while global cooling tends to promote it ...
