EGU: wednesday

A quiet day today (just as well after dinner and drinks last night with reprobate Jeff Ridley and somewhat more respectable John Turner). A bit of ice core stuff in the morning – using d-c-13 to understand glacial methane sources; trying to understand the 41kyr/100kyr switch in ice age cycles. Pic shows view from the…

RP Sr has been pushing his favourite climate change metric – ocean temperatures – and hyping one paper – Lyman et al, that appeared to show a cooling in that metric. It seemed to me rather imprudent to do this based on one untested paper; now unexpected support comes from Lyman et al themselves who…

EGU

Its EGU time again. Monday was a bit of a blur (technically I got to my hotel on monday, about half past midnight. Travelling Air Austria is a lot more pleasant than RyanAir, though). Tuesday was better, partly because I gave up on the stupid “personal programme” stuff the site lets you build on-line and…

Back; and…

I’m back from hols. Sorry for the interruption in service. Can I remind people that if you want to post attacks on other bloggers, the place to do it is their blog or yours not here? I’ve been a bit lax about this but in future such stuff will be deleted

10Be evidence for the Matuyama-Brunhes geomagnetic reversal in the EPICA Dome C ice core slipped by me when it was published last year (Nature 444, 82-84 (2 November 2006)). If they are correct, then its nice for the ice core folk because it provides an absolute tie-point into the marine records. Its also interesting for…

“The warming of other solar bodies has been seized upon by climate sceptics; but oh how wrong they are, says Oliver Morton”. But then he is writing in that dodgy rag Nature, so what does he know? “If the shooting of fish in barrels offends you, look away. The publication this week of a Nature…

Court Rebukes Administration in Global Warming Case says the NYT (thanks to J), and its April the 2nd not first so I guess we can trust them. In a vain attempt to blog this before the usual suspects do, I haven’t bothered to more than skim the report of the decision. But it looks interesting……

Nature has Climate sensitivity constrained by CO2 concentrations over the past 420 million years (subs req, of course). Its interesting for two reasons: firstly as yet another way of getting the same range for climate sensitivity (they get 2.8 oC as a best guess). And secondly as an antidote to the septics who assert no…

Only In It For The Gold

As ever, Michael Tobis’s thoughts are well worth reading.

CarbonTracker is cute (though poss not as much as CarboTracker, which google suggested I might have meant. I wonder how long the explicit “What does CarbonTracker tell us? North America is a source of CO2 to the atmosphere. The natural uptake of CO2 that occurs mostly East of the Rocky Mountains removes only ~30% of…
