Song of the Australian scientists

Australian scientists have begun a push back against climate denial. Over at the excellent The Conversation site (a hugely interesting experiment in bringing academic expertise to the news cycle), Stephan Lewandowsky and a long list of prominent Australian academics have kicked off a series of articles “from the nation’s top minds on the science behind climate change and the efforts of “sceptics” to cloud the debate” titled Clearing up the Climate Debate.

Beginning today, The Conversation will bring much-needed and long-overdue accountability to the climate “sceptics.”

For the next two weeks, our series of daily analyses will show how they can side-step the scientific literature and how they subvert normal peer review. They invariably ignore clear refutations of their arguments and continue to promote demonstrably false critiques.

We will show that “sceptics” often show little regard for truth and the critical procedures of the ethical conduct of science on which real skepticism is based.

The individuals who deny the balance of scientific evidence on climate change will impose a heavy future burden on Australians if their unsupported opinions are given undue credence.

Not to mention imposing a heavy future burden on everyone else on the planet…

Lewandowsky’s introduction was followed in short order by The greenhouse effect is real: here’s why, by Karl Braganza of the Bureau of Meteorology — an admirably succinct statement of the facts of the matter.

The climate of Earth is now a closely monitored thing; from instruments in space, in the deep ocean, in the atmosphere and across the surface of both land and sea.

It’s now practically certain that increasing greenhouse gases have already warmed the climate system.

That continued rapid increases in greenhouse gases will cause rapid future warming is irrefutable.

This is an important series of articles: one worth following in detail. Congrats to Steve and everyone involved.

The wind in the trees

In search of something cheering in the face of the depressing news of continuing increases in the levels of greenhouse gas emissions I found my way to the website of Renewable Energy World Magazine and the welcome reminder that alongside the increasingly dangerous exploitation of fossil fuels the renewable energy industry is making significant progress. I’ll mention two or three recent items out of many from the website to give the flavour of that progress.

Generation Us

Generation Us: The Challenge of Global WarmingAndrew Weaver is a notable Canadian climate scientist. He’s recently written a short book for the general reader to give an easily understandable account of the science of human-caused climate change, to explain its impacts and to suggest solutions. The book is published as one of the Rapid Reads series by Raven Books. It’s titled Generation Us: The Challenge of Global Warming — and if you’re wondering what the title means, it’s a contrast with Generation Me and signifies the moral dimension of tackling climate change.

His account of the science is straightforward. He explains the natural volcanic sources of carbon dioxide and points out that human activities are emitting between 100 and 200 times the amount released by volcanoes and at a very rapid rate. Tens of millions of years of storage of carbon dioxide in coal, oil and natural gas is being returned to the atmosphere in a few decades.

Key contradictions

Gareth’s post on James Hansen’s talk at the University of Canterbury carried a link to a recent report that the Prime Minister supports the intentions of Solid Energy to develop the Southland lignite fields. The contrast between the warnings of Hansen and the bland assumptions of Key was painful.

Key speaks straight business as usual:

“At the moment companies like Solid Energy are growth companies and we want them to expand in areas like lignite conversion.”

“We know there is lots of resource there and we know they potentially have the capability [to convert lignite to urea or diesel] and so we will see how that progresses, but the briquette plant is a good starting point.”

If you watch nothing else today, watch this: Bill McKibben’s recent opinion piece on recent US and world weather extremes illustrated with pictures of the events Bill describes. Excellent work by Plomomedia.
