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.
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 ?
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:
After the RMSTitanic’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.
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 ?
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 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.

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:
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.
I wrote this post for Skeptical Science as part of an ongoing series looking at the arguments made by Christopher Monckton against climate science.
This post examines Monckton’s arguments about global sea ice. Monckton claims:
[T]he global sea ice record shows virtually no change throughout the past 30 years, because the quite rapid loss of Arctic sea ice since the satellites were watching has been matched by a near-equally rapid gain of Antarctic sea ice.
Global Sea Ice Is Decreasing
Have Arctic ice losses truly been balanced by Antarctic gains? The first point to clarify is that we are talking about floating sea ice, not to be confused with land ice. Land ice at both poles and in glaciers around the world is sliding into the ocean at an accelerating rate. This net loss of land ice is contributing to sea level rise.
However, Monckton is clearly referring to sea ice. The rapid decline of Arctic sea ice has indeed coincided with an increase in Antarctic sea ice. But do these two opposite trends cancel out as Monckton suggests? In reality, the upward Antarctic trend is only slight compared to the plummeting Arctic trend. Tamino has crunched the numbers and found the Arctic trend is in fact more than three times faster than the Antarctic one. The net result is a statistically significant global decrease of more than a million km2 – would you agree with Monckton that this is “virtually no change”?
The Skeptical Science team (which includes myself) have recently completed a 16-page booklet called The Scientific Guide to Global Warming Skepticism. (Actually it was completed a fortnight ago, but I forgot to link to it at the time. Anyway, better late than never.)
To quote John Cook’s blog post launching the Guide:
Scientific skepticism is healthy. In fact, science by its very nature is skeptical. Genuine skepticism means considering the full body of evidence before coming to a conclusion. However, when you take a close look at arguments expressing climate ‘skepticism’, what you often observe is cherry picking of pieces of evidence while rejecting any data that don’t fit the desired picture. This isn’t skepticism. It is ignoring facts and the science.
The Scientific Guide to Global Warming Skepticism looks at both the evidence that human activity is causing global warming and the ways that climate ‘skeptic’ arguments can mislead by presenting only small pieces of the puzzle rather than the full picture.
The Guide explains the science in brief, plain language without getting too technical. For those who wish to dig deeper into the science, more detailed treatments can be found at the following pages (often presented with varying levels of complexity from Basic to Advanced):
This post was written for Skeptical Science as the first part of a series on the fake scandal of Climategate.
It’s bad enough that global warming contrarians are successfully misleading the public by propagating misconceptions about climate science. But recently it has become popular to attack climate scientists themselves, to accuse them of fraud and conspiracy. Exhibit No. 1 of the climate conspiracy theory is a collection of emails stolen (or possibly leaked) from the Climatic Research Unit (CRU) of the University of East Anglia (UEA), which appeared on the internet in November 2009.
Founded in 1972, CRU is only a small research unit with around 16 staff. CRU is best known for its work, since 1978, on a global record of instrumental temperature measurements from 1850 to the present, or CRUTEM. CRU’s land surface temperatures are combined with the UK Met Office Hadley Centre’s sea surface temperatures to form the global land-ocean record HadCRUT. CRU has also published reconstructions of pre-1850 temperatures based on tree rings, and CRU scientists have been involved in the Intergovernmental Panel on Climate Change (IPCC).
The 1,073 emails span 13 years of correspondence between colleagues at CRU. Much of it is mundane, but in this digital age it took only a matter of hours for contrarians to do some quote-mining. Contrarians alleged that the CRU scientists had manipulated data to support predetermined conclusions, that they had stonewalled Freedom of Information (FoI) requests for data, and that they had corrupted the peer review and IPCC processes.
The story was quickly dubbed “Climategate”, and it spread rapidly from arcane contrarian blogs through conservative columnists to the mainstream media. The hyperbole was turned up to eleven. Conspiracy theorists had a field day, claiming that anyone even mentioned in the emails, or remotely connected to CRU, must also be part of a conspiracy. In this way, the Climategate conspiracy theory snowballed to include the entire field of climate science. The Climategate emails were held up as “the final nail in the coffin of anthropogenic global warming”, and the media were only too happy to play up the controversy.
The CRU scientists have been cleared
In the months that followed, there were several inquiries into the allegations resulting from the emails. When a few of the more suggestive email quotes are reeled off by pundits without much context, they can sound pretty damning. But each and every one of these inquiries has found no fraud and no conspiracy. Read the rest of this entry ?
