Hi all,

Some great news – Brains Matter has been featured on the iTunes Australia music store on the front page for podcasts:

It’s also sitting at #6 for science podcasts on ITMS Australia:

Sun not responsible for recent warming

Study of climate sceptics

The Great Global Warming Swindle

Hack interview with David Karoly
Some say that the ABC shouldnt be airing it. Others say it’s truth. Hack caught up with David Karoly, a scientist who appears in the debate airing after the documentary

Today I talk with Dr Adrian Gentle, formerly of the Los Alamos National Laboratories, and currently at the University of Southern Indiana, on Einstein’s General Relativity. I would advise you to listen to last week’s episode on Special Relativity as a precursor to this show.

Sun in the clear over global warming
A solar radiation study is evidence that global warming over the past two decades cannot be blamed on the Sun, a theory espoused by climate-change sceptics.

Maths proves the silliness of silly walks
Scientists have explained mathematically why the famous “silly walks” of Monty Python’s John Cleese have never caught on in the long history of Homo sapiens.

New Mars Lander will dig below surface
NASA’s new Mars lander will travel to the Red Planet’s far northern plains to break beneath its surface in the search of conditions favourable to life.

Magnets change the colour of a liquid
Chemists have created a liquid that can be made to change to any colour of the rainbow by applying a magnetic field to it. It has the potential to make inexpensive colour display screens.

The Australian Broadcasting Corporation is showing the mockumentary, masquerading as a documentary, called “The Great Global Warming Swindle”. Unfortunately, it’s being pitched as a documentary, and those who do not have an understanding of science, climatology, or plain logic, may be fooled into believing it.

There have been many deconstructions of it, and it includes bad science, generalisations, straight out lies, and “data” which was based on outdated, or discredited data – yet certain sections of the community would have you believe it’s valid information. It’s worth watching for the sake of identifying the bad science, for your own purposes, but in the meantime, here are some
good links on Geek Counterpoint – Lorne pays equal time to the people who support, and those who deny climate change, and the holes in the extremes of each argument, from a logical perspective.

I wonder if they’ll pay equal time to deniers of other global events (scientific and historical) just because there are a few people out there who deny it…
