quote: The study also finds that enhanced observations in recent decades cannot account for all of the increase. To observe storms in the Atlantic more systematically, meteorologists began relying on data from aircraft flights in 1944 and satellites about 1970. The distinct transitions in hurricane activity noted by Holland and Webster occurred around both 1930 and 1995.
quote: The 2006 hurricane season was far less active than the two preceding years, in part because of the emergence of an El Nino event in the Pacific Ocean. However, that year, which was not included in the study, would have ranked above average a century ago, with five hurricanes and four other named storms.
quote: Chris Landsea, science and operations officer at the National Oceanic and Atmospheric Administration's National Hurricane Center, said the study is inconsistent in its use of data.The work, he said, is " sloppy science that neglects the fact that better monitoring by satellites allows us to observe storms and hurricanes that were simply missed earlier . The doubling in the number of storms and hurricanes in 100 years that they found in their paper is just an artifact of technology, not climate change."...
quote: The hypothesis that increasing carbon dioxide in the atmosphere increases the number of hurricanes fails by an even wider margin when we compare two other multi-decade periods: 1925-1965 and 1966-2006. In the 41 years from 1925-1965, there were 39 U.S. land-falling major hurricanes. In the 1966-2006 period there were 22 such storms -- only 56% as many. Even though global mean temperatures have risen by an estimated 0.4 Celsius and CO2 by 20%, the number of major hurricanes hitting the U.S. declined .

quote: Do you agree that carbon dioxide is having at least some impact on Earth’s current warming?Yes, but you have to give the sun a role. If you include the sun in the right way, the effect of CO2 must be smaller. The question is, how much smaller? All we know about the effect of CO2 is really based on climate models that predict how climate should be in 50 to 100 years, and these climate models cannot actually model clouds at all, so they are really poor. When you look at them, the models are off by many hundreds percent. It’s a well-known fact that clouds are the major uncertainty in any climate model. So the tools that we are using to make these predictions are not actually very good.Do you think then that individuals and societies as a whole need to try to conserve energy? Do you use compact fluorescent lightbulbs, for instance?Yes, yes, we use those. And I ride a bicycle. There are good reasons to conserve our resources and find a more economical way of using energy, but the argumentation is not linked necessarily to climate.
quote: [Laut] presents a figure 1c, which he claims is "a corrected and updated version for Fig 1a", where the correction consists in removing what [Laut] claims are "the irrelevant DMSP data". Laut also removes - without any comments or arguments = the Nimbus-7 data from 79-85....the careful reader [will] note he does not use the same DMSP data in his figures 1a and 1b...this is because the data in fig. 1a are restricted to Southern hemisphere over oceans, whereas fig 1b [is] restricted to midlatitude oceans.It is remarkable that Laut references Kernthaler (1999)..as part of his argumentation against the above work...Kernthaler used the flawed ISCPP-C2 cloud type data, which makes their conclusions obsolete...

quote: …Figure 3 shows the variations since 1970 of the solar cycle means of the sunspot number hRiL, the open solar flux hFSiL, the climax cosmic ray neutron counts hCiL and the solar cycle length L. In each case, the solar cycle variation has been smoothed to give the red line, using exactly the same procedure as described in §3 for figure 3a. Figure 3 shows that the smoothed sunspot number hRiL clearly peaked around 1985 and has declined since and the anticorrelation with L seen in figure 4 has persisted. The open solar flux peaked around 1987, the 2-year lag after hRiL being consistent with the time constant from models of its long-term variation (Solanki et al. 2000, 2001; Wang et al. 2005b). The anticorrelation between cosmic ray fluxes and the open solar flux, observed on both annual and decadal time scales (Rouillard & Lockwood 2004), is here shown to also apply to the trends revealed when the solar cycle is averaged out. hTSIiL has fallen since the peak hRiL in 1985 and this is reflected in the significantly lower peak seen at the current solar minimum than during the previous two solar minima (see figure 1d ).
quote: Our results show that the observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanisms is invoked and no matter how much the solarvariation is amplified.
