Aerosols Mask Global Warming?
“MOST people are under the impression global warming has risen by about 0.8 degrees C since the dawn of the industrial age. Unfortunately, mean temperatures have risen much further when account is taken of the short-term masking effect of aerosols emitted from coal and oil, mainly sulphur dioxide and its oxidized products…
“Thus, according to the IPCC AR4-2007 report (figure SPM.2), the total anthropogenic greenhouse effect since 1750 AD, which is equivalent to about +2.3 degrees C, is masked by a compensating aerosol albedo effect equivalent to about -1.1 degrees C. However, given the short-lived residence time of sulphur aerosols in the atmosphere, this masking effect dissipates within periods up to a few years.
“Currently continuing emission of SO2 maintains the aerosol albedo effect, preventing further sharp temperature rises. But in a situation akin to methadone addiction, proposed reduction of sulphur emissions would lift this barrier, enhancing global warming.

Coral Calcification and Ocean Acidification Revisited
“RESEARCHERS in Australia say the growth of coral on the country’s iconic Great Barrier Reef has fallen since 1990 to its lowest rate in 400 years”, variations of this message have been repeated around the world with global warming, and the associated acidification of oceans, claimed to be the cause. [1]
That was at the beginning of this year, in January, and the media frenzy was based on a paper by Glenn De’ath, Janice Lough and Katrina Fabricius published in the peer-reviewed journal ‘Science’. [2]
Canadian statistician Steve McIntyre has recently had an opportunity to download all the data used to construct the key illustrations that suggested catastrophe.
Mr McIntyre concludes that looking at just yearly averages (above graph) there has been a general trend of increasing coral calcification rates at the Great Barrier Reef since the late 1500s.
In recent years there have been fewer measurements of coral at the Great Barrier Reef and the apparent downward spike in 2004-05 may be an artifact of the data – lack of data. [3]

Media Mention of Sceptics Conference in Washington
Wisconsin Republican congressman Jim Sensenbrenner told a climate change conference in Washington attended by [Australian] Senator Fielding that electricity bills would double or triple under US cap-and-trade legislation. And he denounced the climate change movement as simply transferring wealth to developing countries. Read more here.
