THE United Nation’s Intergovernmental Panel on Climate Change (IPCC), and most others who believe in anthropogenic global warming (AGW), have been influenced by the work of climatologists relying on tree-ring data to reconstruct past climate because the thermometer record only goes back to about 1850.  The claim that there has been an unprecedented upswing in [...]

MOST scientific sceptics have been dismissive of the various reconstructions of temperature which suggest 1998 is the warmest year of the past millennium.    Our case has been significantly bolstered over the last week with statistician Steve McIntyre finally getting access to data used by Keith Briffa,  Tim Osborn  and Phil Jones to support the idea that [...]

MOUNTAIN glaciers in Asia are melting at a rate that could eventually threaten water supplies, irrigation or hydropower for 20 percent to 25 percent of the world’s population: that is according to the latest United Nations Environment Program report.
Lester Brown of the Earth Policy Institute puts it this way, “The melting of the glaciers in the Himalayas [...]

“MITCHELL Taylor is a Polar Bear researcher who has caught more polar bears and worked on more polar bear groups than any other, but he was effectively ostracized from the Polar Bear Specialist Group (PBSG) specifically because he has publicly expressed doubts that there is a crisis due to carbon dioxide emissions. 
“Dr Andy Derocher, the [...]

“IN order for increased human carbon dioxide emissions to cause accelerated global warming, the climate models need to assume that carbon dioxide remains in the atmosphere for a very long time, up to 100 or more years. 

Dear All,
Please find attached a newsletter* with meteorological information updated to August 2009. All temperatures are shown in degrees Celsius.
In the maps showing the geographical pattern of temperatures, the period
1998-2006 is used as reference period. The reason for comparing with this recent period instead of the official WMO ‘normal’ period 1961-1990, is that the latter [...]

THE Intergovernmental Panel on Climate Change (IPCC) assessment reports are a collection of mind numbing statistics from which they claim “solid scientific proof” that man made CO2 is causing global warming. From these statistics empirical formula have been generated which form the basis of the computer programs that are then used to “prove” the empirical formula.
This [...]

In order to take precautions, you have to know what you are taking them against. Some computer models project that the global temperature in ten years time will be warmer than today’s. Other computer models project that global temperature will be cooler ten years hence.   Read more here.

I HAVE been asked several times ‘why am I so sceptical of the anthropogenic global warming (AGW) hypothesis’?  There are many reasons, some of which I have documented in previous articles at this weblog, but these have relied on sometimes complex calculations which I admit can be difficult to appreciate.  So I would like to outline here [...]

THERE was a most extraordinary feature story and then interview last night on the Australian Broadcasting Corporation’s popular late news program with well known reporter and television presenter Leigh Sales giving American journalist Chris Mooney publicity for his new book and a generous amount of air time to explain that anyone who doesn’t believe in [...]
