It’s the environment, stupid

No matter how much The Australian may try to spin the palace coup against Kevin Rudd as arising from his mishandling of a proposed tax on mines, the big swing against Labor in the polls has consistently been towards the Greens.

I’m not sure in what universe The Australian lives, but in this one, people do not desert a ruling party for the Greens out of empathy with embattled miners, at risk of losing some of their massive profits to the public purse.

In 1992, Bill Clinton’s campaign strategist James Carville hung a sign in his campaign headquarters:

The economy, stupid

Given that Labor campaigned in the 2007 election on taking climate change seriously and has achieved almost nothing, with an emissions trading scheme proposal weaker than the Howard administration’s, that has gone on the back burner, maybe they need a reminder:

The environment, stupid

The clean energy imperative

I’m increasingly convinced that the reason for so much opposition to climate change science is not because of some flaw in the science but because there’s fear of the collapse of industrial society if we stop using fossil fuels. This is not an irrational fear but it leads to irrational behaviour like attacking scientists personally, and pay good money to attend vaudeville shows where deniers reassure audiences with rubbish.

The best response is to study clean energy alternatives.

I recently gave a talk at a Transition Towns meeting in Kenmore, Qld. I’ve published a PDF of the slides at scribd, and will add commentary here as time permits. Meanwhile the Kenmore TT people have posted a TED talk on how to roll out the electric car. Interesting.

Thin Green Line

In April 2009, The Australian published an article claiming an ice age is imminent, based on the observation that sunspots were few and far between. The article also contains a completely bogus claim that temperatures dropped 0.7°C in 2007. While the temperature drop claim was pure fabrication (or to be charitable, misreading of a data source), the drop in sunspot count is not, and sunspot numbers correlate very well with solar output. We have just emerged from the deepest solar minimum in nearly 100 years so while the ice age story is obviously ridiculous, we should have had near-record lows the last few years instead of temperatures staying close to record highs.

If this is an ice age, where’s the ice going?

More to the point, a project called GRACE (Gravity Recovery and Climate Experiment), which uses satellites to do accurate measurements of changes in mass on the ground, shows changes in the major land-based ice sheets are pointing in the wrong direction. Mass loss is accelerating [Velicogna 2009], hardly indicative of a slide into an ice age:

The graphs show the monthly change in ice mass. Don’t get too excited by the uptick in the last Greenland months; that reflects moving into northern winter. January 2009 had a significant loss of ice over January 2008. The latest GRACE data has not yet been formally published, but the Skeptical Science site has an update that shows the downward trend continuing into 2010.

What of the Arctic? Some have taken comfort in the fact that Arctic sea ice extent (defined as the fraction of the surface with more than 15% ice) hit an all time low in 2007 and bounced back the next couple of years. The trouble is recent measures of Arctic ice volume [Polar Science 2010] show that even if the area covered with ice hasn’t been shrinking, the volume of the ice has. What’s more, the latest measure of sea ice extent [Artic 2010] has just crossed over the 2007 line (check the latest here):

So if this is an ice age, where’s all the ice going?

The Other Big Issue

Meanwhile the US Gulf oil spill continues almost unabated, more than a month after it started. What this disaster underlines is that more and more often, new oil is going to be found not only in ecologically sensitive situations, but locations where extraction is highly risky. We’ve already seen how hard it is to stop a major leak in the deep ocean. It takes little imagination to see how much harder this would be under Arctic conditions. So drilling for oil in the Arctic has to be considered an extremely high-risk proposition, enthusiasts notwithstanding.

What of alternatives? We’ve known for a long time that oil from coal technology is highly polluting [Chartock et al. 1982], and tar sands are turning out to be even worse [Timoney and Lee 2009].

We are not only facing an end to cheap oil, but we have to face up to the fact that there is no way to replace cheap oil by another fossil fuel without substantial environmental costs. Add to this the fact that these oil substitutes, by virtue of energy-intensive production, contribute much more to CO₂ emissions than conventional oil, and we are facing a very stark choice:

• carry on as if there is no problem and pay an increasingly unacceptable environmental price, or
• make the search for alternatives a top priority.

Where is this taking us?

Exiting from the solar low will almost certainly take us into rapid temperature rise again. We are already seeing an uptick in the first part of 2010 that has no explanation in natural causes. Had we reacted rationally 20 years ago to the earliest indications that harmful climate change was possible by a gradual phased move away from fossil fuels, we would not have a serious problem today.

Consider this analogy. You are contemplating climbing down a steep rocky cliff. You have many years’ experience of climbing, all the best safety gear and have made a thorough study of the rock face, and concluded you have all the risks under control. You want to do your climb under ideal conditions: low wind, good visibility, mild temperatures. I’d say in this situation, go for it. Have a good time and let me know what the view was like on the way down. Now visualise that same cliff. It’s past midnight on a dark night, and a bush fire is raging at your back, rushing toward you at speed, driven by unpredictable gusty winds. You know nothing about rock climbing, have no safety gear and no light. Your only escape from the fire is down the rock face. I wouldn’t give much for your chances.

The failure to deal timeously with the combined issues of climate change and peak oil is putting both the environment and the world economy into the scenario of no option but to dive over a cliff to escape an unavoidable threat. The time to avoid such a scenario is rapidly running out.

Earlier in 2010, the Greens won the balance of power in Tasmania, with an unprecedented vote of over 20%. In the UK election, the Greens won their first seat ever. In Colombia, the Greens candidate for president was at one stage the frontrunner, and has done well enough to go through to a run-off vote.

Collectively, these things amount to a movement. But is it enough? There is a thin green line separating humanity from economic and environmental catastrophe, a catastrophe that is inevitable if we carry on as we are. That’s why the 2010 federal election in Australia is so important: Labor has dropped the ball on climate change, and the Liberals have fallen into abject denial. A big swing to the Greens is the only thing that can pull Australia back on course to dealing with the hard problems – and can send a message to the world that the other green shifts in politics around the world are not a fluke.

The Real Conspiracy

Imagine what you would do if you were an executive in an industry making $100-million a day in profits, and someone came up with some bogus science that threatened your profits. Worse still, this bogus science, if accepted, represented an existential crisis: it would close you down.

What would you do?

Imagine also you are a highly technical industry requiring world-class science to conduct your business and to ensure your future profitability. You therefore have the resources internally to work up an alternative theory or find flaws in the scientific attack on your industry.

What would you do?

Your shareholders would rightly be outraged and demand your scalp at the next stockholder meeting if you did not contest any bogus threat to your continued profitability. If this science is truly bogus, with all your resources, you should easily be able to justify the cost of countering it by doing a definitive study that falsified the bogus theory. So you do your due diligence, and your scientists report back to you.

Let’s now consider two possibilities:

1. the science does turn out to be bogus, or
2. your scientists tell you sorry, the “bogus” science is actually right

In the first case, easy. You publish the results. You publish all the data and computer code, so any scientist can verify independently that you have it right.

Problem solved. The bogus science goes the way of the flogiston theory.

In the second case, what do you do?

Here’s a hint. Is the fossil fuel industry behaving as if the first case applied?
