A 21st Century quiet sun would shave 0.3°C off global warming -- or the last 30-years of observed warming. Right? http://www.washingtonpost.com/blogs/capital-weather-gang/post/could-a-quiet-sun-cancel-global-warming/2013/02/28/156b9f3e-81c8-11e2-a350-49866afab584_blog.html …

THE HOCKEY SCHTICK: New paper finds no increase in tropical cyclones over past 200 years

A paper published today in Palaeogeography, Palaeoclimatology, Palaeoecology reconstructs tropical cyclones in Queensland, Australia and finds that "tropical cyclone frequency did not increase in the past 200 years." The paper adds to many other peer-reviewed publications demonstrating that, contrary to the claims of climate alarmists, tropical cyclones have not increased, and in many cases have decreased due to warming, and are projected to further decrease in the future.

THE HOCKEY SCHTICK: Clouds/aerosols control the climate, not man-made CO2

A paper published today in the Journal of Climate notes that "global dimming" from clouds/aerosols occurred from 1950s to 1980s at a rate of -3.5 Wm-2 per decade, followed by "global brightening" from 1992 to 2002 at a rate of 6.6 Wm-2 per decade. By way of comparison, the IPCC claims* CO2 forcing since the 1950s was 1.18 Wm-2, and .25 Wm-2 from 1992 to 2002, 26 times less than the effect of "global brightening" during the same period. The global temperature record shows that temperatures correspond to these periods of global dimming and brightening rather than the slow steady rise of CO2 levels. It is thus apparent that clouds/aerosols are the "control knob" of climate, not man-made CO2.
