A new paper was published in Nature on 13th September, with Jan Veizer as a co-author, entitled ‘Coupling of surface temperatures and atmospheric CO2 concentrations during the Palaeozoic era.’
The abstract says:
Atmospheric carbon dioxide concentrations seem to have been several times modern levels during much of the Palaeozoic era (543–248 million years ago), but decreased during [...]

Yes, I’ve returned from Spain where 2007 was Madrid’s coolest summer since 1997, ranking 37th in the hottest summers since records began 115 years ago, despite predictions that 2007 would be one of the hottest ever.

Searched for by mariners since the 15th century, the legendary Northwest Passage across the Arctic Ocean appears to have opened up again, according to satellite pictures from the European Space Agency. Satellite measurements of Arctic sea ice began less than 30 years ago. The Northwest Passage is a shipping route between Europe and Asia. [...]

Dear Colleagues,
Following is a chart showing the definite physical relationship between atmospheric carbon dioxide and sea surface temperatures.
It can be regarded as the experience curve of reality.
I used CO2 data from Mauna Loa as it is at a higher elevation and well mixed.
I used recent global average sea surface temperatures based on satellite sensing as [...]

According to Paul Watson from anti-whaling NGO Sea Shepherd, traditional Makah whalers had no plans to resume whaling. Then Watson’s mate Wayne Johnson went out one Saturday morning and killed a gray whale:
According to Lynda V. Mapes reporting for the Seattle Times:
“It was about 6:30 on a beautiful summer morning, with gray whales all [...]

Surely the bans on genetically modified (GM) food crops in most Australian states will be lifted soon?
But the mainstream media keep printing these letter from people like Gill Rosier perpetuating misinformation – in particular the myth that Australia is GM free. David Tribe busted a few myths in his letter to The Age on [...]

A claimed “first world conference on research integrity” opens in Lisbon, Portugal, today. The conference media release explains: “The controversies surrounding the recent assessment report of the United Nations’ Intergovernmental Panel on Climate Change (IPCC) demonstrates how research integrity is a critical issue not only for the science community, but for politicians [...]

Salinity is a significant land management problem in Western Australia but not in Queensland. In 2000 the extent of dryland salinity in Queensland was reported to be 48,000 hectares and rapidly increasing to a level where 3 million hectares were likely to be affected by 2050. It was widely believed that tree clearing had to [...]
