Reading the entrails of chickens

Or, Reading the entrails of chickens: molecular timescales of evolution and the illusion of precision. Pointed out to me by a palaentologist friend. There’s a pdf here. Nothing at all to do with climate, but an interesting tale nonetheless. Or so I assume: it seems sensible, and was recommended by someone sensible, but may have…

CO2 and T over ice age cycles

A reader writes: where is the paleontological data showing the correspondence between CO2 levels and ice age events?. The answer is, all over the place; here is one possible source. The correspondence isvery good. At this point, the s(k)eptics jump up and down and say, aha, but the T leads the CO2. To which the…

The Economist on climate change

The Economist has a special survey on climate change (you get to read the intro for free. The rest is sub-only :-(). Its headlined “The heat is on” and storylined “Global warming, it now seems, is for real.”. [Oh wonderful. I read the special supplement on the assumption that it has most of the content,…

Uprising of the poodles?

If you haven’t been following UK politics recently, you can be excused, cos its been dull. The main story has been “when will Blair go” and “will he name a date”. My reading of this has been, why should he, when no-one has the guts to push him out. Yesterdays news was that the Sun…

Via Prometheus (who misrepresents it) I found Climate Science on Trial: How a single scientific graph became the focus of the debate over global warming. Its well worth reading. Towards the end we have this wonderful bit, demonstrating the sheer ignorance of many of the septics:

CO2 airbourne fraction

http://www.gci.org.uk/briefings/rising_risk.pdf asserts that the “airbourne fraction” of CO2 is coming up to 100%, having been 50%: The point of great concern here is that over the last couple few years 2003/4/5 the rate of increase has jumped to nearer 3 ppmv per annum. This gives a loading of the atmosphere by weight that is roughly…

John Fleck found a great paper by Karl T. Ulrich on the ultimate energy costs of using bicycles versus cars. The bottom-line argument is that cycling saves energy, but because you live longer your lifetime emissions will be greater. Such fun. However: Those who adopt the bicycle as a means of transportation could potentially develop…

Ioke effects

There is a cool pic of Ioke here, which beautifully shows the effect on SST of the hurricane passing over (thanks to CB for pointing this out on the globalchange group). [Small note: Chris Mooney nicked a snapshot of the pic, in case it fades from cache]

pgp / gpg

I have a load of files encrypted with pgp (2.6.2i, since you ask). But the machine at BAS this runs off is soon to be turned off, so it seems I need to upgrade to gpg instead. So… in a break from climate, can I ask the security gurus out there (are any of them…

Gas prices to fall?

Gas prices are currently high and have been rising in the UK… however, British Gas is running adverts in UK newspapers offering “Fixed prices that fall in December 2007″. This might or might not show you the advert, depending on when they update it. Which lead me to wonder if they knew something that no-one…
