Climate Science

Doğu Yakasında Maceralar

15 Mar 2007 by Gavin

Translations: (English)

So that was …. interesting.

First off, I’d like to thank the commenters for all of the suggestions and ideas to the previous post. They were certainly useful. In particularly, the connection with the difficulties faced by evolutionists in debates vs. creationists proved to be very a propos. Our side played it it pretty straight – the basic IPCC line (Richard Somerville), commentary on the how ‘scientized’ political debates abuse science (me, though without using the word ‘scientized’!) and the projections and potential solutions (Brenda Ekwurzel). Crichton went with the crowd-pleasing condemnation of private jet-flying liberals – very popular, even among the private jet-flying Eastsiders present) and the apparent hypocrisy of people who think that global warming is a problem using any energy at all. Lindzen used his standard presentation – CO2 will be trivial effect, no one knows anything about aerosols, sensitivity from the 20th Century is tiny, and by the way global warming stopped in 1998. Stott is a bit of a force of nature and essentially accused anyone who thinks global warming is a problem of explicitly rooting for misery and poverty in the third world. He also brought up the whole cosmic ray issue as the next big thing in climate science.
Update: The transcript is now available – though be aware that it has not yet been verified for accuracy. Audio + Podcast.

Broad Irony

13 Mar 2007 by group

Michael Mann and Gavin Schmidt

[update 3/20/07: The New York Times has run a short letter from us w/ a link to RealClimate for more info (scroll down to 5th letter; the 2nd letter from James McCarthy of Harvard is quite good too, as are some of the others).]

The first rule when criticizing popular science presentations for inaccuracies should be to double check any ‘facts’ you use. It is rather ironic then that William Broad’s latest piece on Al Gore plays just as loose with them as he accuses Gore of doing.

We criticized William Broad previously (Broadly Misleading) for a piece that misrepresented the scientific understanding of the factors that drive climate change over millions of years, systematically understating the scientifically-established role of greenhouse gases, and over-stating the role of natural factors including those as speculative as cosmic rays (see our recent discussion here). In this piece, Broad attempts to discredit Gore’s “An Inconvenient Truth” by exaggerating the legitimate, but minor, criticisms of his treatment of the science by experts on climate science, and presenting specious or unsubstantiated criticisms by a small number of the usual, well-known contrarians who wouldn’t agree even if Gore read aloud from the latest IPCC report.

Küresel Isınma Müzakeresi

12 Mar 2007 by Gavin

Translations: (English)

Küresel Isınma Müzakeresi

Ingilizce’den çeviren Figen Mekik

Richard Sommerville (UC San Diego) ve Brenda Ekwurzel eşliğinde (Union of Concerned Scientists-Endişeli Bilim Insanları Birliği), 14 Mart Çarşamba günü küresel ısınmanın kriz olup olmadığını tartışacağımız bir müzakereye katılacağım. Bu pek farkına varılmadan geçip gidebilirdi (benim pek çok halka açık konuşmam gibi) ama bu sefer karşı tarafta Michael Crichton, Richard Lindzen ve Phillip Stott var. Iki tarafın da tezini savunan ayrı birer yazı (ben ve Stott yazdık) ABC news sitesinde var. Müzakere’ye biletler çoktan satılmış, bitmiş. Ama müzakere hem radyoda (NPR, mesela WNYC de Cuma-23 Mart- sabahı 8:20de) yayınlanacak hem de bir podcast hazırlanıyor (ama canlı olmayacak sanırım). Internet sitelerinde bir de anket var.

Ben buna pek hevesliyim, ama bazı çelişkili düşüncelerim de var. Böyle bir müzakereye katılmak, küresel ısınmanın olup olmadığının hala tartışmaya açık olduğunu savunmak mı oluyor? Bu tip çekişmeler, oradaki insanları bilimsel konularda eğitmeye yarar mı? Bu hem eğlenceli hem de eğitici olabilir mi? Ya da ciddi bir muhalefeti geçerli kılmaya mı yarıyor? Yoksa bloglarla uğraşmaya ayıracağım zamanı buraya giderek boşa mı harcamış olacağım? ;)

Tüm fikirlerinize açığım.

Aldatıldık: Carl Wunsch Cevap Veriyor

12 Mar 2007 by group

Translations: (English)

The following letter from Carl Wunsch is intended to clarify his views on global warming in general, and the The Great Global Warming Swindle which misrepresented them.

Partial Response to the London Channel 4 Film “The Global Warming Swindle”

Carl Wunsch 11 March 2007

I believe that climate change is real, a major threat, and almost surely has a major human-induced component. But I have tried to stay out of the `climate wars’ because all nuance tends to be lost, and the distinction between what we know firmly, as scientists, and what we suspect is happening, is so difficult to maintain in the presence of rhetorical excess. In the long run, our credibility as scientists rests on being very careful of, and protective of, our authority and expertise.

Aldatıldık!

9 Mar 2007 by group

Translations: (English)

By William and Gavin

On Thursday March 8th, the UK TV Channel 4 aired a programme titled “The Great Global Warming Swindle”. We were hoping for important revelations and final proof that we have all been hornswoggled by the climate Illuminati, but it just repeated the usual specious claims we hear all the time. We feel swindled. Indeed we are not the only ones: Carl Wunsch (who was a surprise addition to the cast) was apparently misled into thinking this was going to be a balanced look at the issues (the producers have a history of doing this), but who found himself put into a very different context indeed [Update: a full letter from Wunsch appears as comment 109 on this post]

So what did they have to say for themselves?

‘Cosmoclimatology’ – tired old arguments in new clothes

9 Mar 2007 by rasmus

Translations: (Português) (English)

Image from cosmosIn a recent issue of the journal Astronomy and Geophysics (A&G), Henrik Svensmark coined a new term: ‘cosmoclimatology’ . I think ‘cosmoclimatology’ is a good and refreshing name for anything combining our cosmos with our climate. However, all other aspects of the article I found very disappointing. We have already covered most of these topics before, but the A&G articles provides us with some new aspects to discuss. Furthermore, Svensmark is the Director for Center for Sun-Climate Research, Danish National Space Center, and therefore influential. He is also the co-author of a recent book with Nigel Calder that received some attention. Furthermore, a laboratory experiment of his also managed to make some headlines. It seems that solar forcing is one of the sceptics’ last trenches in the debate about climate change. In my view the A&G paper therefore merits a comment as long as the same old and worn arguments resurface without discussing misgivings from the critics.

Kasırga Ateşi

1 Mar 2007 by Gavin

Translations: (Português) (Français) (English)

The big problem with much of the discussions about trends in hurricane activity is that the databases that everyone is working from are known to have significant inhomogeneities due to changes in observing practice and technology over the years. So it’s not surprising that a new re-analysis (Kossin et al, published yesterday) has been generating significant interest and controversy among the hurricane research community (see e.g. Prometheus or Chris Mooney). However, rather than this study being taken for what it is – a preliminary and useful attempt to make homogeneous a part of the data (1983 to 2005) – it is unfortunately being treated as if it was the definitive last word. We’ve often made the point that single papers are not generally the breakthroughs that are sometimes implied in press releases or commentary sites and this case is a good example of that.

Round up and thanks

25 Feb 2007 by group

A few tidbits from around that may be of interest:

  • Tom Yulsman is running a new blog (now linked in our blogroll) for the Center for Environmental Journalism at U. Colorado, Boulder, covering climate change as one of his ‘beats’.
  • The Global Roundtable on Climate Change (GROCC), made up of business leaders, NGOs and academics released a statement on climate change. (Coverage BBC, Reuters)
  • The UN Foundation (an independent NGO established to support the UN mission) has helped put together a site called ‘IPCC facts‘ to help with the outreach associated with the IPCC Fourth Assessment. We haven’t examined every page, so if there are any questions, this is as good a place as any to go over them.

On the lighter side, those people who are fond of the offsetting concept (usually applied to carbon emissions) may find this site interesting (hat tip to Yarrow).

Finally, the more multi-lingual of our readers may have noticed the proliferation of translations of RC posts in recent weeks. We now have regular contributors translating articles into French, Slovak, Swedish and Portugeuse (as denoted by the hybrid flags associated with relevant articles). We can offer them nothing more than our deep gratitude – recent contributions have been from: Valérie Masson-Delmotte, Fernando Manuel Ramos and Ivan Bergier Tavares de Lima (ClimaGaia), Alexander Ač, Olivier Daniélo, Etienne Pesnelle, Jacob Wallström and Yves Fouquart. Many thanks to all!

(And if anyone else would like to help out on an occasional basis translating posts to their native language, please let us know. )

Update: And now turkish! (thanks to Figen Mekik).

Climate Reporting in Physics World

23 Feb 2007 by rasmus

Translations: (Português) (English)

PhysicsWorld cover, Volume 20, no. 2, February 2007 The February 2007 issue of PhysicsWorld contains several articles relevant to climate research, with a main feature article on climate modelling written by Adam Scaife, Chris Folland, and John Mitchell, and a profile on Richard Lindzen as well as an article on geoengineering in the ‘News & Analyses’ section. The magazine also contains an article (‘Living in the greenhouse’) under ‘Lateral Thoughts’ that brings up a bunch of tentative analogies to a wide range of topics completely unrelated to the greenhouse effect in a technical sense, and an editorial comment ‘Hot topic‘, arguing that it would be wrong of PhysicsWorld to ignore those outside the mainstream. To be more precise, the editorial comment devotes a few lines justifying the profile on Lindzen and the report on geoengineering, with a reference to a Feynman quote: “There is no harm in doubt and scepticism, for it is through these that new discoveries are made”. Wise words! Nevertheless, I cannot resist making some reflections.

Aerosols: The Last Frontier?

21 Feb 2007 by group

Translations: (Português) (English)

Guest commentary from Juliane Fry, UC Berkeley

The recently released IPCC 2007 Fourth Assessment Report Summary for Policymakers reminds us that aerosols remain the least understood component of the climate system. Aerosols are solid or liquid particles suspended in the atmosphere, consisting of (in rough order of abundance): sea salt, mineral dust, inorganic salts such as ammonium sulfate (which has natural as well as anthropogenic sources from e.g. coal burning), and carbonaceous aerosol such as soot, plant emissions, and incompletely combusted fossil fuel. As should be apparent from this list, there are many natural sources of aerosol, but changes have been observed in particular, in the atmospheric loading of carbonaceous aerosol and sulphates, which originate in part from fossil fuel burning. While a relatively minor part of the overall aerosol mass, changes in the anthropogenic portion of aerosols since 1750 have resulted in a globally averaged net radiative forcing of roughly -1.2 W/m2, in comparison to the overall average CO2 forcing of +1.66 W/m2.
