Says he doesn't do drama (ref to IP's heated delivery)



Q1 Andrew Watson. Says that submarine volcanoes are included. A: IP says that degassing before and after eruption not measured.

Climate catastrophists are engaged in trade and business. They are similar to creationists. Ignore data. It's a cash cow. We're all doomed, pay the rent. They use consensus and frighten the politicians. Punter knows the argument has moved on and the cake has been overiced.

Cacophany about agw has damaged science enormously

Calling people climate deniers is advertisement of people's ignorance. co2 is good

Long term record shows little relationship between co2 and temp

Warm times are good

Nothing unusual about the present

Current temperature changes are pathetic compared to past

Development of plants reduced co2 in atmosphere

Lots of calculations show that atmospheric lifetime of co2 is short. Only one or two suggest not.

All this co2 not going into calculations of carbon balance

Seamounts on ocean floor still erupting. giving off co2. But these are not measured. Known for years.

Supervolcanoes under the ocean are little studied.

Gas volcanos have been investigated thoroughly, but not included in normal measurements of volcanism because no lava.

Reaction of seawater with volcanic rock is a buffer. When we run out of rocks on sea floor we can worry about acidic oceans

Submarine volcanoes are the elephant in the room

Degassing of c02 before and after relationship. Close relationship of atm co2 to volcanoes

About 1500 volcanoes. Only hear about terrestrial volcanoes

% co2 in atmosphere has been up to 20% in the past



Q2 Explain regime change. What was it? Metastable states change. Nobody knows why, but well described in literature.

Q1 Chris Hope Judge bus school. What predictions does HS make about ocean heat in next 10-15 years? A: Might see a cooling. If sun is going down, and temps rise then it's not the sun.

Solar effect appears to be large. If exclude solar or regime change, then it makes anthropogenic look much bigger. These effects are not well covered by climate models.

Can effect be seen in climate? Use ocean heat content. Forcings = volcanoes, gcr, anthropogenic and a regime change in 1977. Solar effect ~1Wm-2, compares well with Shaviv. If remove solar effect left with apparent rgime change in 1977. This can be seen in eg tropospheric temps.

Coronal mass ejections - decrease in gcrs at earth - forbush decrease. Is there an atmospheric response? Liquid water in clouds over oceans fall after forbush decrease. Ditto in low clouds etc. Aerosols ditto

Always lots of nucleation centres in atmosphere. Is this right?

Use trace gases in atmosph concentrations. Change amount of ionisation. See if you get more aerosol particles. SKY experiment.

Correlation between low clouds and GCRs - but need mechanism. Ions?

Discussion of LIA and solar. Solar irradiance too small to explain Need amplification mechanism - clouds.

Get correlations between eg stalagmite 18O and solar variability

One particle entering atmosphere generates shower of particles - incl ions which change chemistry

CRs accelerated by solar events - supernovae.

He's older than I thought.



Q2 Was Maunder minimum effect European. A: Probably stronger in Europe. 1863/4 was coldest. Two years later v warm. What is probability that we go into a minimum and co2 stops us starving.

Q1 Shapiro paper discussed. Not sure I understand this!

In warming world Europe could get cooler

Could have Maunder minimum conditions soon

Global responses to forcings from Lean and Rind - discussion of solar in Eurasia. Blocking events. \do these have solar dependence? 8% decrease when solar output high

Can explain with caveats warming in terms of el nino, co2 and other anthropogenic and solar

But changes in sun since 1985 don't match temp rise - in wrong direction

TSI not enough to explain observed warming

Lockwood says Svensmark's ideas are beautiful and clever but effect may be slow and limited to clean maritime air


Lockwood and Svensmark

Discussion of different solor outputs and how they reach the atmosphere

Lockwood says stewardship of planet immportant issue for grandchildren


Andrew Watson

All done

Q2 ??? Feedback for h20 is not positive. Also no trpospheric hot spot. A: many uncertainties. Possible that RH has gone down. That's why wide uncertainty estimates.

Q1 Mike Kelly. Can we estimate past h20 levels. What is the effect? Can be done. Doesn't know answer.

Such rapid change is rare in Earth history

Good reason to believe that this  will change ckimate. Not certain.

Increase in co2 definitelyanthropogenic

Long calc to get to estimates. Includes estimate of climate sensitivity which gives estimate of rate of rock weathering.

No long term measurements of co2 (>550my). Only proxies.

Talking about co2 lagging temp. V uncertain Not consistent with idea that co2 is a cause he says. yay!!! Consistent with amplifying effect.

Close relationship between atm co2 and antarctic consistent with greenhouse theory.

Discussion of water vapour as a GHG.

Radiative transfer calcs are well known and simple

Decline in atmospheric o2 matches rise in co2, so co2 can't be coming from volcanoes. Must be burning of fossil fuels. Oceans and land taking up co2

No more questions

2nd Monckton - asking about 60yr perioddicity and PDO. Can we detect AGW. PJ says yes.

1st question Tony Kelly of GWPF. Sea temps fundamentally different to land. Should measure marine air temp. Says sst doesn't agree to land. PJ says SST correlated to marine air temp

Questions next

And that's it

Satellites - same results as surface

SST - bucket adjustment is the most important. Also shift to buoys

Discussion of CRU subsampling studies - still get same result

BEST 2% series shown. We are getting the message that all the series show roughly the same thing.

homgeneity/urbanisation  adjusts have small effect

CRUTEM4 will include a full release of station data

adjustments to stations makes little difference at large scales

"Population growth is not a great metric for urbanisation trends"

Urbanisation. Little difference in urban/rural

Biases in order of importance form Jones and Wigley. 1 SST bucket 2. Thermometer ecposure, 3. Urbanisation

Some discussion of Menne et al 2009 - bimodal distribution of adjusts

PJ discussing homogenity issues

We've been told we will be evicted if we mention climategate

Lovely Georgian theatre here.


Sense about Science lecture

Times Higher Ed has a report about last night's Sense About Science lecture by Cambridge historian Richard Evans. From the sounds of it, this was pretty interesting, with Prof Evans noting that calls for the public to trust scientists are  "inadequate" given the propensity of scientists to get things wrong - he cites the BSE and miasmatism as examples. That said, Prof Evans, like so many others finds it difficult to cope with dissenting voices, and you sense that underneath he longs for consensus and certainty and a nice-neat top-down world. But I wonder if there is some significance in the fact that climate change sceptics were no mentioned alongside the anti-vaccinators (is that a word?,) who he gives as examples of the fringe groups who have taken advantage of the public distrust of scientist.

If someone can lay their hands on the video, do please post a link.


CRU book group

Members of the CRU book group couldn't wait to see what Phil Jones was going to suggest as the title for next month...

Conference proceedings

I'm now safely esconced in Cambridge, which is all very nice. Thanks to the generosity of BH readers I have invested in a 3G wireless dongle, so I should be able to report regardless of the facilities available, although battery power and my ability to type on a netbook will potentially be issues.

The conference is organised by a small charity called the Howard Trust, who appear to have no prior involvement in climate matters. The programme is pretty packed. Proceedings kick off at 9:30am and Jones is first on, speaking about the measurement of global temperature.


AGW hype dying

Scottish Sceptic notices a dramatic change in MSM coverage of the global warming issue. It  appears that the cold weather last winter just killed off the majority of any remaining interest in the subject. Remarkable stuff.

Read the whole thing.


Upcoming events

Next week, I'm off down south for a couple of days. The purpose of the visit is to attend a conference to which I've been invited. This promises to be fun, with a positively stellar list of speakers:

  • Phil Jones
  • Andrew Watson (of "Morano is an asshole" fame)
  • Mike Lockwood (of "Svensmark is all wrong" fame)
  • Henrik Svensmark (of "no I'm not" fame)
  • Nils Axel Morner
  • Ian Plimer
  • John Mitchell (of "no IPCC working papers" fame)
  • Nigel Lawson
  • Vaclav Klaus

The balance of speakers is not quite right, with nobody there to put the Stern review side of the economic arguments, but it's hard to argue with the calibre of speaker the organisers have recruited. The suggestion in the invitation was that the organisers see the event as forming an opportunity for compromise between the two sides of the global warming debate.

I will try to liveblog at least some of the proceedings on Tuesday, wifi availability and battery life permitting. Josh will be on hand to do the visuals.

If anyone wants to help defray the cost of the trip, your contributions to the tip box will be gratefully received.

[The conference is invitation-only, but Phil Jones is doing a repeat of his talk at the University of Lancaster on Friday (h/t Aztek) for those who are interested.]



Oz chief scientist: I'm a lobbyist

If anyone was under any illusions about the true role of government chief scientists, this interview with the new occupant of that role in the Australian civil service should dispel them.

Science advocate

Chubb says that he will be a proactive lobbyist for science, helping the government and the public to appreciate the role of science in coping with the major challenges facing society. Doing this, he says, should help to insulate science from budget cuts. "If we can get science and its value to the community sufficiently high up the priority list," he says, "the job should be half-made each year before you go into bat for specifics."

Commendable honesty, but why on earth should scientists have their own lobbyists on the inside of government? This reminds me of the recent scandals here in the UK, where healthcare trusts were revealed to be paying for union reps out of the public purse. Paying for union reps and paying for lobbyists does not seem materially different to me. Either way, these recipients of all this public largesse are not working for the benefit of the people but for themselves and their pals.

I wonder if Sir John Beddington also sees himself as a union rep for the scientific community who just happens to be paid out of public coffers?


Interview with Johnny Flynn

I chanced upon this interview with Johnny Flynn, who played the role of Ben Shotter in The Heretic - the global warming play I reported on a few months back. It's from the education pack prepared for the show, which can be seen here. Other members of the show's team are interviewed as well, but I thought Flynn was very thoughtful. 


What did you find most exciting when you read the play?

Initially it challenged my preconceptions about something I thought I knew. Because you go along with the orthodox perception of these issues and it basically made me really challenge what I was doing about these things, and in some ways compounded what I really felt about the issues of climate change. In my particular case it made me feel like making a more of a concerted effort to make sure my personal efforts were conscious and mindful. So it’s interesting as each different character has a different standing on the issues. My character is an eco warrior to start with and has quite a woolly approach to what he thinks he’s got to do, and then he’s challenged by this brilliant teacher who sits slightly on the other side of the fence. But instead of necessarily bringing him to her camp she just tries to sharpen up his foundations, and what it is he’s acting on. And that’s what it did for me. It makes you sift through whether bandwagons are easier to be attached to, and just know why you’re doing it; peer pressure or common consensus and political persuasions and things like that.

Please tell me this isn't true

From here:

Students in a Society and History (SAH) class on “the Impact of Climate Change” at a Tasmanian high school, must donate to a Canadian environmental organisation in order to be awarded points in a “scavenger hunt” and to gain marks.
