RODGER, PROFESSOR
GRAHAM SHIMMIELD,
PROFESSOR BOB
DICKSON AND
PROFESSOR ANDREW
WATSON
Q440 Chris Mole: Should we charge
the Met Office or Proudman, or somebody, with having a long-term
monitoring role?
Professor Watson: I think it would
be a good idea to have an agency that had that role, yes.
Q441 Chris Mole: Do others share
that view?
Professor Rodger: I accept there
is a need for long-term monitoring, I accept there is a need to
do it in an integrated way, but whether you need a separate organisation
is one that I am less convinced by. It is about integration. As
I have said to some of you before, the earth is an integrated
system and exactly which box you draw there are always going to
be people on the edges of that box or outside that box.
Q442 Chris Mole: Is it not a problem
that things keep just falling off the monitoring list if there
is not somebody charged with doing it? We nearly lost SAHFOS a
while ago.
Professor Dickson: The point you
made is an interesting one about whether monitoring is mindless
monitoring or whether it is research. In many cases, and you used
sea gliders in the example, we are waiting for sea gliders that
will work under the ice and within the shelf, for example. We
are waiting for sea gliders that will go all the way to the ocean
floorthey do not at present. So these are very intense
research efforts that are going on necessarily in only a few places.
The ones we use come from Seattle. That is a whole new research
topic just now and eventually it will be used for monitoring.
Q443 Chris Mole: I think, Professor
Watson, you touched on the numerical climate change modelling.
We are talking about gliders and buoys and things; you can buy
an awful lot of them for the super-computing power we need to
get a step-change. Where is the balance there? Do we need that
super-computing power tomorrow or should we spend the money on
buoys and gliders?
Professor Watson: Moore's law
states that computer power doubles every 18 months, or something
like that, but what we actually need is to be able to run a model
at eddy-resolving, which is 10 km resolving, for 1,000 years with
the full ocean physics and chemistry and biology, and we still
need to wait for, probably, 20 years of Moore's law doubling before
we will get there. You asked for the balance: it is certainly
true that with the current modellingthe Argo programme,
for example, has dramatically increased the usefulness of the
short-term modelling that we are doing, so that was very well
worth spending. There are some other areas where we certainly
need to spend more on monitoring, and that will come before the
computing. However, the computing is desperately important.
Q444 Chris Mole: We have been world-leading,
have we not?
Professor Watson: We have been.
Q445 Chris Mole: Are we about to
lose that?
Professor Watson: I do not think
so. My impression is that we are still very good. In the oceans
in particular there has been something of a hiatus and the new
model that the Hadley Centre will be using shortly is actually
a French modelfor which we have to swallow our pride! It
is a good model. In general, we are doing very well.
Q446 Chairman: Just before we leave
the super-computing, we heard from the previous panel, and we
have heard this on a number of our inquiries, about the lack of
super-computing capacity in the UK. Do you feeland this
is just a question outside this brief but it clearly affects itthat
UK, either through STFC or some other body, needs in fact to actually
concentrate on that issue of providing super-computer capacity
in order for us not to have simply the large climate change models
but models for all sorts of other areas as well? Is this a weakness
in British science or are you not able to answer that?
Professor Rodger: All areas of
science are benefiting from high degrees of super-computing. It
is one of the things that Britain has been, traditionally, excellent
at, in high-resolution super-computing. It is one of the things
that we can hold up as a flagship. What it offers us is the integration,
often, and that is a very powerful activity, that you can bring
data and theory together.
Q447 Chairman: I am not arguing against
this.
Professor Rodger: I would argue
that you could use more super-computing across the board in science.
Q448 Chairman: I just wanted to know
whether it is actually holding us backthe lack of super-computing
power and availability. But you do not believe that is the case.
Professor Rodger: We need multiple
runs, for example, in the environment rather than a single run;
we do not have the resources to run as many multiple, high-resolution
runs for as long as we would wish at the current time.
Q449 Chairman: Okay. Thank you very
much indeed. Professor, Shimmield, you spoke earlier about partnerships
and co-ordination, and it has been a feature of this inquiry that
there are a very significant number of partnershipsin fact,
often, too many to mention. We have got the Marine Climate Change
Impacts Partnership, the Marine Environment Change Network and
the Office for Climate Change. Do they make a ha'ppeth of difference
and do scientists actually get very much involved with them?
Professor Shimmield: You are right
to identify a range of partnerships and arrangements. Going to
the next level down you will see where some of the differences
are; some are more focused on the impact of biodiversity in the
coastal systems as a consequence of climate change; some are more
directed at climate change consequences on the human populations
and coastal zone management. I think what you may be alluding
to is the need to have some better integration between these activities.
They probably show the breadth and pervasiveness of understanding
climate change impact across the marine and terrestrial environment.
Q450 Chairman: How effective are
these partnerships? How involved are you?
Professor Shimmield: I think they
have been quite effective in producing some of the new status
reports that are coming out; we are able to see in a more holistic
way some of the inter-annual variability in climate change impacts,
particularly on shelf seas around the UK. That is one definite
benefit that has come out of some of the partnerships.
Professor Watson: I am from a
university and, at the coalface, fairly well down the food chain
here, but I would have to say that many of these do not make a
lot of difference at the practical level of the day-to-day doing
of the research. The best ones are those which do involve, from
my perspective at least, the people who are actually doing the
research and not simply those that are talking about it and doing
reports.
Q451 Chairman: Which ones?
Professor Watson: For example,
the IGBP (that is the International Geosphere-Biosphere Programme)
which has a Committee that sits nationally, and there is the GER
Committee (Global Environmental Research Committee) that sits
under the auspices of the Royal Society. Those Committees are
very useful; they organise meetings, for example, that one may
go to.
Q452 Chairman: I will move on briefly.
Do you think that NERC does a good job in co-ordinating the whole
of climate change science including work on the oceans?
Professor Rodger: NERC, well,
who is going to answer this question?
Q453 Chairman: Professor Rodger,
you are a good advocate for NERC.
Professor Rodger: Thank you very
much for that. NERC in the past has taken a different role in
the sense that it has often seen itself as a funding agency. Under
its new Chief Executive it is definitely trying to be more directed,
more focused, and therefore there are particular activities where
there is an attempt to do much more co-ordination, much more addressing
the critical question. So in the new strategy you will find "climate
change" and then under there you will only find six or seven
key questions that are to be addressed, so I think again we are
at a point of change where we are going to be more integrated
and more directed at addressing the key questions that are relevant
not only to the UK but internationally, globally.
Q454 Chairman: Any other comments?
Professor Dickson: The funding
of the Hadley Centre by Defra is one major strength in the UK
and I must say that when we look at, for example, the NERC programmes
in the ocean in the north for the IPY, they are done in collaboration
with the Hadley Centre effort, as is the remote sensing of ice
freeboard in University College London, so the thing I like about
it is that there are a number of departments and agencies who
are all well aware of each other's abilities and the need to feed
back and forth in an iterative way between observations and modelling,
so I wouldn't say it is just NERC.
Q455 Dr Spink: Chairman, can I just
take us on to the next question. On specific programme funding
such as the global ocean observing systems and climate variability
programmes, should these be funded direct from NERC, would that
improve them, or should they come through specific programme fundings?
Professor Rodger: Again I think
we go back to what we said; I do not think it matters as long
as it is done.
Q456 Chairman: With respect, Professor
Rodger, that is not satisfactory, is it, because unless somebody
takes ownership of it
Professor Rodger: --- unless somebody
takes ownership of the question
Q457 Chairman: --- then it could
easily slip off the radar here.
Professor Rodger: Going back to
your question then, I think Defra has to take a significant responsibility
for defining the problem and then encourage NERC and make sure
NERC and the other organisations carry out the requirements.
Q458 Dr Spink: So there needs to
be better co-ordination then?
Professor Rodger: Yes.
Professor Watson: I would say
that I very much welcome NERC's new strategy on which there has
been widespread consultation, but historically I would say NERC
has not done a great job of co-ordinationas Alan says perhaps
they are going to change because of that. The problem is, as I
say, that NERC is very focused on its own institutes and it does
not necessarily know what is happening in the community as a whole
which is quite a lot larger than the institutes. There is a reorganisation
of government science and the universities now coming together
under a new department.
Q459 Chairman: Do you support that?
Professor Watson: I certainly
would. I think that that is a good idea and perhaps an opportunity
to get this co-ordination across the piece a little better than
it has been done in the past.
Chairman: Okay, on that note I will pass
to you, Brian.
