Fire as a Threatening Process: A Note from Roger Underwood

By

ABOUT two months ago I received a “heads-up” from a mate who works in Canberra that Environment Minister Peter Garratt was considering listing prescribed burning as a threatening process under the Environmental Protection and Biodiversity Act. At first I thought this was nonsense, but then I reflected on the attitudes towards prescribed burning that we hear constantly from some well-known academics and environmental groups, and it suddenly seemed highly likely. So I wrote a letter to Prime Minister Kevin Rudd, seeking clarification. All of this was going at about the time of the catastrophic bushfires in Victoria.

I have now received a reply to my letter.  It was written by Ms Kerry Smith, an Assistant Secretary with the Department of Environment, Water, Heritage and Arts. Mr Rudd had forwarded my letter to the Minister for the Environment, who in turn forwarded it to his Department, where it eventually filtered down through the Department’s Approvals and Wildlife Division to its Wildlife Branch and thence to the Species Listing Section. 

I now realise that the situation is complex and has many ramifications, as demonstrated by the following advice from the Department:

Note to President Obama: The Science is Not Settled

By

“Few challenges facing America and the world are more urgent than combating climate change.The science is beyond dispute and the facts are clear.” President-elect Barack Obama, November 19, 2008

With all due respect Mr. President, that is not true.

We, the undersigned scientists, maintain that the case for alarm regarding climate change is grossly overstated. Surface temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now.1,2 After controlling for population growth and property values, there has been no increase in damages from severe weather-related events.3 The computer models forecasting rapid temperature change abjectly fail to explain recent climate behavior.4 Mr. President, your characterization of the scientific facts regarding climate change and the degree of certainty informing the scientific debate is simply incorrect.

Empty Promises and Gridlock: Bjorn Lomborg Reflects on Earth Hour

By

YESTERDAY the power failed in Sydney’s central business district and there was chaos.   The cross-city tunnel was closed and many people became trapped in lifts in high-rise buildings and in traffic gridlock.  This reminder of the importance of electricity came to the city that invented Earth Hour and just two days after Earth Hour 2009.   

The following piece written by Bjorn Lomborg reflects on the Earth Hour campaign and alternatives, he writes:   “A real danger is that Earth Hour convinced people we were making progress on climate change when we were not. And it let business and government off the hook. There is still no cheap replacement for the carbon that we burn. This is the reason many promises of drastic CO2 cuts remain just empty promises and why past global agreements to cut CO2 have gone unfulfilled.  A meaningful solution to global warming needs to focus on research into and development of clean energy, instead of fixating on empty promises of carbon emission reductions.”

White Possum Back from Extinction, but Now Possum Man Has Gone Bush

By

LATE last year academic Stephen Williams, from James Cook University, reported that a rare species of white possum was possibly extinct and that this was likely the first recorded mammalian extinction due to global warming.   Not surprisingly his claims attracted much media interest. 

Now Professor Williams has rediscovered the white possum and the media is reporting “Extinct possum back from the dead”. 

This morning I tried to phone the Professor to get more information and temperature records.   The phone went to message back, and there was a reassuring message letting me know he wasn’t far away.   I then sent the following detailed email and got the following reply a little while later: “I will be away in the field until 7th April with limited email access.”

I think the questions in my email to Professor Williams are relevant and hopefully he can answer them on his return.
