Is the PDO elephant knocking at the door again ?

NASA has just drawn our attention to their interesting map of the PDO (Pacific Decadal Oscillation) anomaly for April 14–21. As NASA says, “…while the La Niña was weakening, the Pacific Decadal Oscillation—a larger-scale, slower-cycling ocean pattern—had shifted to its cool phase.”

This issue is important to the “greenhouse” debate and arguments over the […]

“Core-mantle magnetic flux shifts probably driving climate change”

This is the claim of Peter Ravenscroft who has a web page including a graphic showing the relationship between core-mantle magnetic flux and a proxy ice core temperature record going back 800,000 years.

He also says that evidence indicates this theory can explain the warming we are all aware of in Siberia and the […]

Warming threat underestimated, says Lord Nicholas Stern

In a welter of breathless press articles the Australian media touched the forelock to the latest from Lord Nicholas Stern’s latest puff trying to frighten us all about Global Warming following his last effort in October 2006. The first subject he addresses is claiming the oceans are increasingly saturated with CO2 and will be able […]

Climate Change – has it been cancelled?

Bob Carter discusses greenhouse effect and climate on YouTube – I cannot see where Bob can be contradicted.

Hadley Centre versus Reynolds (NOAA) SST data

Subtitle: “0.45 deg C per Century warming in Hadley Centre sea surface temperature (SST) data for both hemispheres compared to Reynolds (NOAA) SST data 1982-2008″

I have been surprised at the magnitude of the hemispheric differences between HadSST2 and Reynolds V2 SST data, equivalent to 0.45 degrees C per Century.

In 2006 I found errors […]

Sunspot 990 04/14/2008 by VE3EN at 22:05

The new sunspot has been numbered 990 by NOAA. This is now officially the 2nd sunspot of Solar Cycle 24. […]

Northern hemisphere warming more rapidly than the south

University of Alabama at Huntsville (UAH)) MSU satellite temperature data for the lower troposphere still has the northern hemisphere warming at a greater rate than the southern. In March 2008 the difference is trending at a huge 0.52 degrees C over the 29 years (352 months) of the data, Dec 1978 to Mar 2008.

Large warm anomaly over Asia in March while tropics cool; is this due to mass transport of tropical air ?

UAH MSU satellite temperature data for the lower troposphere has the globe still cool while global oceans and the tropics are still cooling. However the northern extratropics have warmed in February and March and an anomaly map from the NOAA Climate Diagnostics Bulletin for March shows this warmth to be over Asia. I am interested […]

Reporters ‘pressured not to write negative stories’ about Earth Hour

For those in the big wide world, Earth Hour was a Green stunt in Australia on March 27 to turn off lights to save power thus reducing carbon emissions, thats the theory. Excerpt from story in THE AUSTRALIAN: JOURNALISTS at The Age yesterday condemned management for undermining the Melbourne newspaper’s editorial independence, claiming reporters were […]

Canberra water supply, sensible options sidelined by Govt in thrall of IPCC climate models.

This long term rainfall trend for the Uriarra district west of Canberra near dam catchments indicates that the low rain period starting 2001 is nothing exceptional and could well represent a return to the pre 1945 lower rainfall regime. Contrary to the thrust of conclusions from CSIRO climate modelling. There is no evidence linking the […]
