The Sydney Morning Herald and climate change denial

November 8th, 2008

The Sydney Morning Herald’s website (and I assume the paper) is carrying a lead article denying the reality of climate change. The main claim is a rather common one spouted by denialists – that the change has stopped over the last ten years. It is important to look at the trends in the data properly, and over at Science Blogs A Few Things Ill Considered looks at the argument.

The SMH article then goes on to cite the work of Richard Linzen without noting his ties to the oil and coal industries, or his track record of less than accurate statements.

Things that may or may not be of interest…

October 29th, 2008

So, what has caught my eye online today?

  • Science Daily reports on a study of cleaner wrasse behaviour which looked at cooperation between cleaner wrasse pairs in servicing larger fish. At one point I was thinking about getting a cleaner wrasse for the tank which hold by moon wrasse, two maroon anemonefish, a bicolor angel and three humbug dascylluses, but apparently the cleaner wrasse is rather persistent in seeking food and will harass tank mates too much in a small tank. They also tend not to get enough to eat and often die early. I’m now holding off on cleaner wrasse until I have a really big tank with some big fish.
  • Another Science Daily story discusses cooperation between spinner dolphins while hunting. “To match their 3,200-calorie-per-day diet, they need to eat at least 650 fish each night – plus enough extra to fuel the energy they burn during the hunt, perhaps another 200 to 300 fish.”
  • Cairns’s Trinity Wharf, an old and rather dilapidated building on the south side of the City centre, is finally going to be upgraded to provide a decent arrival point for cruise ships. The existing facility really is awful. The upgrade is long overdue.
  • Wired Science reports on a solar system 10.5 light years away that may have Earth-like planets. We still don’t have a means of observing Earth-sized planets at these distances, but future equipment should be able to do so. No reality TV broadcasts have yet been detected coming from the system, so intelligent life may be a possibility.
  • At Scientific Blogging, Massimo Pigliucci has an interesting post up about the platypus genome and what it tells us about evolution.

Internet censorship coming to Australia

October 17th, 2008

The Rudd government is planning to implement its $126 million Plan for Cyber Safety. This was sold to Australian voters as a means to prevent children from accessing inappropriate content, but will include mandatory filtering for all Australians. If you opt out of the child-safe filter, one would assume you get unfettered access but you would be wrong. Instead, you will be put onto a lighter version of the filter that filters content from a “blacklist of illegal and prohibited content” decided upon by the government.

Exactly what will be considered illegal and what will be prohibited isn’t clear, but there are concerns for sites dealing with topics such as euthenasia, drugs and political protest. Such a filter will also slow net connections significantly as well as incorrectly blocking some other websites. A trial was conducted by the Australian Communication and Media Authority, and found:

  • One filter caused a 22% drop in speed even when it was *not* performing filtering;
  • Only one of the six filters had an acceptable level of performance (a drop of 2% in a laboratory trial), the others causing drops in speed of between 21% and 86%;
  • The most accurate filters were often the slowest;
  • All filters tested had problems with under-blocking, allowing access to between 2% and 13% of material that they should have blocked; and
  • All filters tested had serious problems with over-blocking, wrongly blocking access to between 1.3% and 7.8% of the websites tested.

Thoughts on capitalism vs communism, and the mixed market alternative

October 13th, 2008

I continue to read Naomi Klein’s excellent the Shock Doctrine – an expose of the way in which fundamentalist free market ideology has caused so much damage. The power of corporations is immense, drowning out the voice of the people. Crisis was not only welcomed but, at times, manufactured in order to allow non-democratic policies to be introduced, giving national wealth to corporations, concentrating wealth in the hands of the few. Their mantra isn’t just that greed is good, it’s that crisis is good because it allows the changes necessary to allow greed to run free. It’s scary to read about people thinking that comparison to Pinochet was a compliment.

The Friedmanites ignored Klein for a while, but have started trying to defend their guru. When I read their defences I am struck by how light weight they are, nit-picking over minor details while leaving her central thesis intact. It’s hard to see how they can do otherwise, as Friedman’s own words condemn him. We need a return to the middle ground. Neither of the two extremes, communism and laissez faire capitalism, are an answer to our problems. I’m starting to wish I had paid more attention in economics class when I was young. In trying to understand the issues, I’ve found myself at the Guardian’s website quite a bit.

Joseph E Stiglitz, winner of the Nobel Prize in Economics in 2001, weighs in:

A sad day for Wall Street, but it may be a glorious day for democracy. Hopefully Congress will now devise a plan that is not based on trickle-down economics. A plan that identifies the real sources of the problem and does something about them – a real stimulus to the economy, a real programme to stem the flood of foreclosures, and a transparent programme for filling the holes in bank balance sheets. A plan that assures US taxpayers the costs will be borne by those who created the problem. Accountability means paying for the full consequences for one’s actions – and the financial system has much to account for.

Gary Younge’s piece, to which I linked yesterday, should be mentioned again. It is an excellent read. Its conclusion is rather memorable:

“Capitalists can buy themselves out of any crisis, so long as they make the workers pay,” said Lenin. It is rarely regarded as common sense to quote him in polite company. Yet as a description of what is taking place right now, it is the most sense I’ve heard in a long time.

David Marquand writes on the need for a new economic theorist to take the lead, one echoing Keynes after the Great Depression and World War II, one that will help reform capitalism to serve the people better.

The need now is for clever regulation, on a global scale. In the EU, there is an equal need for much stronger political institutions to complement the central bank. But the greatest need of all is for a new theory of the mixed economy, framed for the global marketplace of today, as the now-defunct Keynesian system was framed for the national post-war economies. In the early 90s, economists like John Kay and Will Hutton were groping their way towards such a theory, but when New Labour won its crushing victory their work was buried. It’s time to return to the charge.

The Guardian is becoming a regular visit for me. Previously it was their Science section, with excellent podcasts and coverage of the Large Hadron Collider, that drew me to it, now the business section is also attracting my eye.

Things that caught my eye

October 10th, 2008
  • Queensland’s DPI is going to try a new method of eradicating tilapia – they’ll be damming a creek, stunning the fish, removing as many natives as possible, then introducing a poison to kill the tilapia.
  • A Florida woman has been hospitalised after a dolphin jumped into her boat. I’m almost jealous.
  • The United Kingdom uses anti-terrorist laws to throw Iceland’s banks even further into chaos. Odd to think that Iceland is apparently a terrorist nation in the UK’s eyes.
  • Sex reversal has been documented in a Lake Malawi mbuna. This is something I have wondered about when seeing some changes in one of the mbuna I own. I don’t think mine has actually changed, but she has developed some masculine characteristics. Maybe I should run my own experiment. The cichlid family is fairly closely related to the wrasses, parrotfish and damselfish families, and sex reversal is fairly common in them.
  • Quite a few years ago I read a biomechanics article about gecko feet in which it talked about how they utilise Van Der Waals force to adhere to surfaces (rather than suction cups as many people think). Later I read the Gecko’s Foot by Peter Forbes, which talked about attempts to create artificial versions of some of nature’s designs, including gecko feet. New Scientist is carrying a story about US chemists creating a nanotube fabric that is even stickier than gecko feet. This could lead to new adhesives for general use, like sticking irritating children to chairs.

Paul Keating discusses the Wall St crisis on Lateline

October 5th, 2008

Last week Paul Keating appeared on Lateline and talked about the current situation on Wall St. Much of the discussion centred around levels of debt both in the US and in Australia. I found it to be a very interesting interview. You can see a transcript or video over at the Lateline website.

Pat Condell on Sharia Law in Britain

October 5th, 2008

Via RichardDawkins.net comes this YouTube video in which Pat Condell discusses the introduction of Sharia Law courts in the United Kingdom. The video was temporarily blocked by YouTube after complaints from Muslims, but after review it was made available again.

Information on Sharia courts in the UK is available at the Times Online.
