The Climate Show #14: volcanoes, black carbon and crocks from Christy

[youtube]ytuB78XIqjs[/youtube]

A busy news week sees Glenn and Gareth discussing volcanoes in Chile and Africa, busy pumping ash into the atmosphere and disrupting flights in South America, Australia, New Zealand and the Middle East, an extreme spring in the USA, drought in Europe and a warm autumn in NZ, a new UN report on black carbon and how a reduction could cut future warming, Aussie scientists fighting back against climate denial, and forecasts for the summer ice minimum in the Arctic. John Cook from Skeptical Science deals with their new series on John Christy’s climate crocks, and introduces a great new graphic front end for the SkS climate literature database, plus we cover price reductions on solar panels, LEDs on streetlights in San Francisco and MIT’s Cambridge crude.

Rebuilding on a rising tide

It’s been a shaky week in Christchurch and Canterbury. Another M6.3 shock hit the city on Monday afternoon — renewing the misery for many in the city’s eastern and seaside suburbs, but thankfully not adding to the death toll. Attention has now turned — with some force — to the question of which suburbs should be rebuilt, and an excellent feature by David Williams in last Saturday’s Press on sea level rise and its implications for the rebuilding of Christchurch should cause some pause for thought. Williams interviewed James Hansen during his visit to the city last month (shortly before I did, in fact), and uses Hansen’s views on sea level rise to kick off his discussion:

Hansen says a multi-metre sea level rise is possible this century if greenhouse gas emissions, caused by things such as coal-fired power plants, vehicle engines and agriculture, are not reduced.

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.

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.

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.
