Liberals Part 1: Climate denial and deregulation

11 January 2013

Almost all of my posts to date have focused on criticizing Australia’s incumbent Labor government. I have written very little about the alternate Liberal/National Coalition government. But as we enter an election year, it is time to examine the Liberals’ policies.

Can the Liberals be trusted?

To begin with, it is worth noting that the Liberals have given us every reason to distrust them on climate change.

According to a 2010 survey, only 38% of Coalition politicians accept that humans are warming the planet (compared to 98% of Greens, in line with the scientific consensus, and 89% of Labor politicians). Liberal and National politicians regularly spout denialist talking points, up to and including their leader Tony Abbott. Most notoriously, Abbott reportedly said in 2009 that the science of climate change is “complete crap” but “the politics of this are tough for us”. In 2010 Abbott met with Christopher Monckton, a man who claims climate scientists are conspiring to fake their results in a plot to create a socialist world government. In a speech to the Mining Council of Australia in 2011, Abbott said “the authors of the carbon tax do not see coal, oil and gas as the most important parts of our economy” but “as a threat to the very survival of our planet”, the obvious implication being that his party disagrees. In 2011 former Liberal Prime Minister John Howard launched a book instructing schoolchildren to raise denialist arguments in the classroom. Queensland’s Liberal National government wants to remove climate from the school curriculum, and its Premier and Environment Minister openly deny human-caused global warming.

I could list many more examples. Indeed, it would probably be quicker to list Coalition politicians who have never publically made denialist claims.

Almost all of the Liberals’ actions mark them as an anti-climate party. The Liberals did not take any significant climate action during the eleven years of the Howard government. They consistently prioritize short-term economic considerations like mining industry competitiveness and electricity prices ahead of climate change. Today they are putting way more effort into opposing Labor’s climate policy than in designing and promoting their own (the former is the subject of this post; the latter will be covered in Part 2). Thus it is questionable whether they would even implement their climate policy, let alone whether it would work. Read the rest of this entry ?

Is Tony Abbott a liar, or just plain stupid?

25 August 2012

It’s taken them two-and-a-half years, but it looks like the Australian media is finally beginning to cotton on to the blatant dishonesty of Tony Abbott, leader of the Liberal Party and Opposition. His latest mistruths are debunked here. What better time than to recall some highlights from his ever-growing litany of false, misleading, and contradictory statements?

“Liar” is an inflammatory term which I used to get your attention. Of course, I have no way of knowing the motivations of Abbott or his party; they may believe themselves to be sincere. But if “liar” means “one who makes false statements”, then Abbott is a habitual liar. In fact, I can logically prove to you that Abbott is a liar. This is possible because if a politician promises one thing to one audience and a contradictory thing to another audience, it logically follows that one of those promises must be untrue.

Abbott claimed in July 2011 he had been consistent: “I once used some colorful language describing the so-called settled science of climate change but look, climate change is real, humanity does make a contribution to it and we’ve got to take effective action against it. I mean, that’s my position and that’s always been my position but I’ve never been in favor of a carbon tax or an emissions trading scheme.” But in October 2009, he had said: “We don’t want to play games with the planet so we are taking this issue seriously and we would like to see an ETS.” And he is on video advocating a form of carbon tax immediately after denying climate change:

Titanic and Global Warming

15 April 2012

After the RMS Titanic’s collision with an iceberg a century ago today, the passengers did not believe the ocean liner would sink. The ship was so gargantuan and stably designed it showed few outward signs of being in imminent danger, and took 2 hours and 40 minutes to sink. But sink it did. The Earth’s climate is rather like the Titanic: an enormous beast that is deceptively stable and slow to respond to disturbances.

(Source: Wikipedia.)

The parallels between global warming and the Titanic disaster begin before the collision, with the failure to heed iceberg warnings. If you’ll forgive me for quoting Wikipedia:

The North Atlantic liners prioritised time-keeping above all other considerations, sticking rigidly to a schedule that would guarantee their arrival at an advertised time. They were constantly driven at close to their full speed, treating hazard warnings as advisories rather than calls to action. It was widely believed that ice posed little risk […] Titanic‘s future captain, Edward Smith, declared in an interview that he could not “imagine any condition which would cause a ship to founder. Modern shipbuilding has gone beyond that.” Read the rest of this entry ?

Get ready for the carbon bubble

20 February 2012

Remember the sub-prime mortgage bubble? The next economic bubble could be caused by investing in the unsustainable fossil fuel industry. The idea might sound incredible, but it results from our failure to seriously address the science of climate change.

The science tells us we can’t burn all fossil fuels

Fossil fuels formed over millions of years from dead plants that were quickly buried, removing carbon from the atmosphere in the process. Thus fossil fuels contain carbon which has been out of circulation for up to hundreds of millions of years. Yet humans are digging up this carbon and burning it in the space of a few centuries. When carbon (C) is burned, it reacts with oxygen to produce carbon dioxide (CO2), a heat-trapping greenhouse gas.

Carbon dioxide from fossil fuel burning is the main cause of anthropogenic global warming, now far outstripping natural influences on climate. Carbon dioxide in the atmosphere is like radioactive waste: much of it hangs around for a very long time. As long as humanity continues to burn fossil fuels, carbon dioxide will continue to accumulate in the atmosphere and the Earth will continue to warm. The urgent need to prevent further warming leaves us with no choice but to phase out fossil fuels as rapidly as possible.

In the words of NASA climatologist James Hansen, saying what other scientists have generally failed to communicate, “we cannot burn and emit to the atmosphere most of the remaining fossil fuels”. If we wish to avoid unimaginable global catastrophe – or to meet the target the world’s governments have agreed to – let alone to limit global warming to a level anywhere near what scientists consider safe – we must leave the vast majority of the planet’s fossil carbon in the ground.

The conspiracy to capture the Australian media

5 February 2012

If you’ve paid attention to the news recently then you may know Australian mining billionaire Gina Rinehart has been buying up shares in TV channels (Network Ten) and newspapers (Fairfax Media). What you may not be aware of is a video of Christopher Monckton and other climate change deniers plotting how to “capture” the Australian media to promote their views.

The video has to be watched to be believed. It’s surreal, almost like something out of a conspiracy thriller: a cabal of crazy people plotting how to control the media, and thus control people’s thoughts. Though Monckton may be prone to delusions of grandeur (this is coming from a man who believes he’s found the cure for AIDS), the things he says in this video are actually plausible.

Christy Crock: Do the observations match the models?

21 April 2011

I wrote this post for Skeptical Science.

At the recent US House of Representatives Committee on Science Space and Technology climate hearing, the Republicans called Dr. John Christy as an expert witness testifying against the global warming consensus. Unfortunately, Christy spent his time repeating a long list of climate myths, including the common contrarian refrain that “climate model output does not match up to the real world”. Let’s examine this claim.

A tale of three climate indicators

Surface temperature observations are well within the range of model projections:

A basic overview of melting ice around the globe

17 February 2011

I wrote this post for Skeptical Science as a basic rebuttal of the argument “Ice isn’t melting”.

Contrary to contrarian claims, ice is melting at accelerating rates in the Arctic, Antarctica, Greenland, and glaciers all over the world. Arctic sea ice has shrunk by an area equal to Western Australia, and could be all gone in a decade.

Ice sheets are beginning to shrink

An ice sheet is a huge layer of land ice. The only ice sheets are in Antarctica and Greenland.

The Greenland ice sheet is losing mass at an accelerating rate. In recent years the ice loss has spread from the south coast around to the northwest.
