There is a 20 questions Q & A paper attached to the WMO “Scientific Assessment of Ozone Depletion: 2006”.

In the second column in Question 2 – near top right page Q4 – is the statement:

“Some stratospheric ozone is transported down into the troposphere and can influence ozone amounts at Earth’s surface, particularly in remote, unpolluted regions of the globe.“

Natural processes that can cause injection of stratospheric ozone down into the surface layer will happen regardless of whether the location is above “…remote, unpolluted regions of the globe.” or above urban and inhabited areas.

I think the WMO should rewrite the above very odd passage – without any spin.

There is a controversy about the origin of common high levels (circa 50-100ppb) in peak daily surface level ozone measured at non-urban stations.

The WMO view would emphasise that these are due to mass transport of polluted urban air – outward to rural sites.

The opposing view that I see evidence for in my studies of hourly air monitoring data – is that daily ozone peaks can form in rural air due to natural ozone precurssor chemical species.

Dr Fred Singer’s, SEPP Science Editorial (copied below) #1-09 (1/3/09) in “The Week That Was” (TWTW), address’s the issue of the difference between University of Alabama in Huntsville (UAH) [Christy and Norris, 2006] and Remote Sensing Systems (RSS) (Mears and Wentz 2005) MSU lower troposphere (LT) temperature data[1979-2007].

Dr Singer refers to the Heartland Institute publication which he edited, “Nature Not Human Activity Rules the Climate”, where Fig’s 9a and 9b seen below, indicate the effect of the hypothetical correction that is required in the RSS data. In a nutshell, the red squares should plot further to the right to agree closer with the blue squares.

The RSS MSU_LT anomalies show a greater warming trend 1979-2008 than do UAH and the majority wisdom around the pro-IPCC Blogosphere is that RSS are correct and UAH wrong.There is also published peer-reviewed evidence that a cooling correction to RSS is required. Randall and Herman Jan 2008 say in their abstract:

“..Diurnal correction signatures still exist in the RSS LT time series and are likely affecting the long-term trend with a warm bias.”

There is more in their paper which I do not have.

The Douglass and Christy paper (Accepted by Energy and Environment Aug 2008) “Limits on CO2 Climate Forcing from Recent Temperature Data of Earth” has an Appendix A. “Comparison of MSU and RSS” where the authors address the issue and conclude that there is a positive jump of 0.136 degrees K in RSS at about 1993, when two satellites briefly overlapped.

I agree with Dr Singer that this is indeed a significant correction that is required in RSS LT MSU.

North Atlantic Oscillation

From Climate Science: Roger Pielke Sr. Research Group News, very much worth your time to read. I think it is fair to say Dr Henderson-Sellers has been a long term supporter of the IPCC and it is stunning news that she is publishing her reservations.

Contrast this with the evangelical certainty of the Rudd Government (Australia) rushing policy to save the planet, at colossal cost to all Australians. For what benefit ? I would say zero measurable effect on global climate.

The source article on the Pielke site includes:

The rush to emphasize regional climate does not have a scientifically sound basis

Until and unless major oscillations in the Earth System (El Nino-Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO) and Atlantic Multidecadal Oscillation (AMO) etc.) can be predicted to the extent that they are predictable, regional climate is not a well defined problem. It may never be. If that is the case then we should say so. It is not just the forecast but the confidence and uncertainty that are just as much a key.

Climate models need to be exercised for weather prediction; there are necessary but not sufficient things that can best be tested in this framework, which is just beginning to be exploited.

Energy budget is really worrisome; we should have had 20 years of ERBE [Earth Radiation Budget Experiment] type data by now- this would have told us about cloud feedback and climate sensitivity. I’m worried that we’ll never have a reliable long-term measurement. This combined with accurate ocean heat uptake data would really help constrain the big-picture climate change outcome, and then we can work on the details.

Al Gore Calls Myanmar (Burma) Cyclone a ‘Consequence’ of Global Warming. Gore claimed global warming is forcing ocean temperatures to rise, which is causing storms, including cyclones and hurricanes, to intensify.

Lets take a look at the FACTUAL EVIDENCE.

First the lower troposphere in the tropics has been COOLING over 16 months.

When we take a closer look, the NASA Earth Observatory has a series of illustrated articles on Cyclone Nargis including this map showing its formation and track.

We see it forming NE of Sri Lanka in late April.

Lets look at Sea Surface Temperatures (SST) for that area in late April, viewing SST global anomaly maps at this NOAA (USA Govt) website.

This anomaly map is from 27 April to 3 May and shows SST’s were if anything slightly cooler than normal.

You can go to this NOAA archive and check back for earlier weekly SST anomaly maps and there are no relevant warm anomalies.

So I say to Al Gore, please ex-Senator Gore, check your facts before speaking to the world.

He also says that evidence indicates this theory can explain the warming we are all aware of in Siberia and the Antarctic Peninsular.
