The big fuel cell

Solvay’s 1 MW Nedstack Fuel Cell Delivers Impressive Performance During its First Two Months

We don't read enough about fuel cells and their potential contribution to cleaner energy. At the link above, you can see the photo of a very big one in Belgium, being run successfully for a couple of months, and apparently can power about 1400 homes.

A question of influence

BBC News - Did Charles Dickens really save poor children and clean up the slums?

The BBC looks at the question of how influential Dickens really was for social reform in the 19th century. Maybe not quite as much as people think, say some historians; but this has an air of pop contrariness about it if you ask me.

Climate change stuff

* Skeptical Science has a good post explaining Hansen's recent paper that details why they expect rapid warming in the near future.

* At Real Climate, a post on the study of tree rings, showing they don't well reflect cooling caused by volcanic activity. The end result is that this may have led to some underestimates of climate sensitivity.

* Nature reports that some measurements of the amount of leaking methane from at least one natural gas field indicate that gas may not be much better than coal for the warming atmosphere. There seems to be uncertainty as to how representative this is of other gas production areas, but it is still a bit of bad news.

Around the solar system by nuclear power

Robert Heinlein, writing in the the 1950's, used to have families cruising around the solar system via simple nuclear powered rockets (I remember the family discussion of the merits of different rocket models in The Rolling Stones - also known as Space Family Stone) and it may yet turn out that nuclear propulsion will be what gets astronauts around in future.

This report notes that NASA has had highly variable funding for nuclear rockets over the years, but they still think it has a lot of merit and may yet re-fund it to more realistic levels.

It's always going to be a bit controversial, though, getting the fuel into space on the top of a controlled explosion.

Speaking of Heinlein, I've recently bought a couple of Charles Sheffield novels from second hand stores. I've been reading him on and off for years, and am currently half way through The Web Between the Worlds.

He really does strike me as writing very much in the style of early Heinlein. He is more technically minded, but the way he sketches characters, has a basic optimism for the future of humanity, only ever implies sex and never describes it, and throws in the occasional off hand bit of future quirk (of the type "the door dilated", or "he took a bulb of beer") reminds me of Heinlein all the time.

I find him a very entertaining science fiction writer, and it's a pity he does not quite seem to have had the recognition he deserved. (He died a few years back.)

gulfnews : Black magician stabs man 'to cure illness'

Time for a bizarre black magic story, this time from India:

Patna: The Bihar police have arrested a black magician who ruthlessly stabbed a man claiming that it would cure him of his mental illness and help him lead a normal life.

The 55-year-old accused was apprehended on Friday evening while he was stabbing the victim Taleshwar Murmu (45) at the latter's residence in the Mehboob Khan locality in eastern Bihar's Purnia district.

"The more you endure the pain of the stab, the faster the cure," the black magician kept on telling the victim who, police said, kept on screaming loudly due to the severe pain from the stabbing.

Zapping away fatherhood

'Sonicated' Sperm: Scientists Test Ultrasound as the Next Male Contraceptive | Healthland | TIME.com

Have I posted a story about this before?* I can't quite remember, but anyway, from the report above:

In the study, the rats’ testes were exposed to high frequency ultrasound at 3 MHz for 15 minutes each, two days apart. The sessions were enough to kill the existing sperm in the testes and stop the development of additional sperm. The first study to look at the effect of ultrasound on sperm production, in the 1970s, showed that the depletion was temporary, and Tsuruta hopes his studies will show the same result...

Some men are keen to get in on the technique:

Tsuruta stresses that the procedure isn’t something you should try at home, despite the fact that commercial ultrasound machines are available online and men are apparently purchasing them for this purpose. “I get emails asking me what conditions men should use,” Tsuruta says. “This is really not something you should do at home because we don’t know nearly enough about its safety and reversibility and what other effects there might be long term.”

I'm not sure that something that is working to disable sperm cells could be trusted to not be causing damage to testicular cells you don't want damaged.

* Yes I did - in 2010. It was a story about the same researcher in fact, and I am not entirely sure why this has made it to the news again last month.

Floods, politics and engineers

There's always been the very strong whiff of a Right wing witch hunt against the dam operators following the Brisbane flood. It would seem this happened with unusual haste because:

a. there is Labor government in power;
b. a theory instantly developed that, being a Labor government, it had fretted too much about releases from Brisbane's water supply because it believed climate change warnings that longer droughts are coming;
c. people like to blame someone, if it is at all possible, when natural disasters happen.

Why the government should be penalised at all, even if there was any evidence (I don't think there is) that it withheld recommended water releases out of concern for future droughts is a complete puzzle, given this report from October 2010, barely 3 months before the flood, when water was being released due to spring rains:

Seqwater said all south-east dams were receiving heavy inflows from surrounding catchments after heavy rainfalls across the region.

The water body’s decision to open the flood gates at the officially 100 per cent full Wivenhoe came under fire from the state opposition.

Opposition spokesman Jeff Seeney told parliament the dam was not completely full.

“Is not this release of water from Wivenhoe Dam, when it is holding only 40 per cent its available storage capacity, a clear indication that the government has learnt nothing from the water crisis,” Mr Seeney said.

But Natural Resources Minister Stephen Robertson said the extra capacity was needed to prevent a repeat of the 1974 floods.

“What Mr Seeney on behalf of the LNP suggests is that Wivenhoe Dam should not be used for flood mitigation purposes,” Mr Robertson said.

“As a result, that puts into jeopardy the very safety of people in Brisbane and surrounding areas.”

And on 20 December, only a few weeks before the flood, Deputy Opposition Leader Springborg repeated in detail the same view (that the dams should store more water, not less) on Brisbane radio.

The decision was made (post flood) to reduce dam levels seeing there is still a La Nina weather pattern hanging around, but I can't say that I have noticed evidence that anyone influential was being outspoken about reducing dam levels in anticipation for summer 2010/11.

In any event, the flood enquiry has taken a curious turn, after having finished its report and sent it to the printers, by virtue of journalist Hedley Thomas (who was running around promoting an "independent" expert or two who were pointing the finger at dam management almost before the flood subsided.)

It turns out that the inquiry seems to have missed that in emails and notes circulating at the time of the flood, the dam engineers were not talking about the same response levels as their later formal report to the Commission indicated.

The dam engineers have therefore been recalled and grilled over how they wrote their report: the accusations of fraud and cover up have flown fast and thick from the Counsel Assisting the inquiry: I have had the feeling that their new found aggression is partly due to the fact that a journalist has shown up the well paid lawyers, as much of this evidence was already before the inquiry, just its importance seems to have been missed.

So, the basic problem is that although the manual gives escalating classifications of response, each involving discretionary faster releases of water, on the weekend before the flood, the engineers were being rather careless to record what level their actual response was at. It even seems a bit unclear whether they recognised the level they were at. So (if I understand it correctly) when writing the report, after an incredibly tiring and stressful period, they looked at how much water they had started releasing, combined with other inflows coming into the river, and petty much retrospectively nominated that they had moved to level W3 by the Saturday morning.

This isn't an ideal way to demonstrate that you were working in accordance with a manual. In fact, in evidence on the last day, one engineer seems to have acknowledged (unwisely, if you ask me) that not knowing what level your response was at would constitute a "breach of the manual". This raises a good philosophical question: if you do the same things a manual would have required just based on your own judgement, you may not have been "following the manual," but have you actually "breached" it?

As far as I could tell from some of the figures, the move out of the lower W1 response did, for much of the weekend, involve not a whole lot more water than the maximum W1 release. (I could be wrong on that, though, as the chief engineer said it was clear that they skipped level W2 and went straight to W3.)

But - given that other independent engineers have already said they think the dam operators mitigated the flood as best they could - getting too hooked up on demonstrating compliance with the manual should surely not triumph over the practical outcome of how they operated it.

As I understand it, each response classification is triggered by the dam reaching certain levels, and it seems the dam engineers certainly recognised the significance of the threshold levels being reached. In other words, they did increase water flow as levels grew, and they did make decisions as to how fast to release water based on how fast the dam level was responding. The manual even at level W3 allows them to consider problems caused downstream by flooding the highest bridges near Fernvale, and they also took that into account in deciding rates of release.

The thing is, as far as I can tell, the manual does not say (at least at the first 3 levels - W4 is doing whatever must be done to save the dam) "once level X is reached, reduce dam levels by Y metres as soon as conceivably possible." And you wouldn't want it to. If there was blue sky forecast for the next week, you wouldn't want to be flooding Brisbane for no real reason.

So: surely you are always going to have to rely on judgements of the dam engineers as to rate of release based on a variety of factors that it is probably difficult to define precisely for all circumstances.

The importance is the outcome, and those who say they should have released a lot more water starting on the Saturday are, of course, doing this with the advantage of hindsight about what was soon to become record inflows into the dam. There must be hundreds of ways to model how releases could have been done differently - but high early releases would have caused earlier flooding of the lowest areas, and how do you recognize at the time the release rates which will turn out to strike the "ideal" balance?

I therefore await the inquiry's findings in this regard with some interest. Non compliance with the manual is said to have significant legal implications, as it would allow class actions. I wonder, however, whether a finding of non compliance might allow legal cases which nonetheless fail due to inability to prove negligence, or flood levels that would have been significantly lower. Surely insurance companies won't get paid much, or at all, if some modelled difference amounts to less than (say) 30 cm? And hydrology seems a rather imprecise science anyway. Lots of Brisbane flooded on land the Council did not expect would flood in a repeat of the 1974 flood - and this one peaked lower.

So the engineers have my sympathy, as do the politicians; the lawyers and the journalists - not much at all. In fact, I suspect Mr Thomas may only be giving false hope to a bunch of witch hunters.

UPDATE: as Hedley Thomas and the Courier Mail are hell bent on criticising the engineers (and just about everyone else associated with the enquiry,) you have to read another media outlet to get the same point I was making. From the ABC:

If the commission finds the engineers breached the operating manual, then it opens the Government to a class action, which law firm Maurice Blackburn estimates could exceed $1 billion.

Insiders question that figure, but regardless of the record keeping both Mr McDonald and an independent hydrologist have found the four engineers released the appropriate amounts of water and that has not yet been challenged.

If it stays that way, it means the only damage from these allegations are to the reputations of the four men.

A very worrying virus, somewhere in a freezer

Norman Swan ran an extraordinarily scary interview on the Health Report last week that put a lot of detail on that recent avian flu research story.

To be honest, I hadn't paid all that close attention to the controversy until now, but the details in the interview really surprised me. For example, the influenza pandemic of 1918 managed to kill about 90 million people with a mortality rate of 2%.

The bird flu in nature appears to transmit rarely between humans or mammals. The man made variety, however, spread airborne to infect about 80% of ferrets used in the experiments, with a 60% mortality rate.

And some of this is sitting in a freezer somewhere, and the details of how to make are pretty obvious to many scientists from information put out already.

Mind you, as a terror weapon, it is surely the equivalent of all out nuclear war - no one would want the world it leaves. I think the bigger worry is its accidental release, as well as the news that there appears no reason why natural mutations of bird flu won't turn as deadly, eventually.

You should read the whole thing...

Climate Change Okay for One Coral - ScienceNOW

Climate change/ocean acidification skeptics will be onto this sooner or later, so we may as well mention it first. On the west coast of Australia, porites coral seems to be doing fine, with the benefits of warming outweighing any acidification. The article notes that this seems to be in contrast to the Great Barrier Reef, although I expect someone has probably argued that the run off effects from a much larger coastal population might be behind the coral slow down there.

Anyway, ocean acidification is just getting underway, as well as increasing sea temperatures which lead to bleaching events. I wouldn't rush to forecast the next 100 years based on this.

Encouraging, kind of

New generation of nuclear reactors could consume radioactive waste as fuel | Environment | The Guardian: A new generation of "fast" nuclear reactors could consume Britain's radioactive waste stockpile as fuel, providing enough low-carbon electricity to power the country for more than 500 years, according to figures confirmed by the chief scientific adviser to the Department of Energy and Climate Change (Decc)....

The engineering firm GE Hitachi has submitted an alternative proposal based on their Prism fast reactor, which could consume the plutonium as fuel while generating electricity.

However, the Prism design is a sodium cooled reactor, said to have passive safety. I've always felt that liquid sodium doesn't sound all that safe. But what do I know? (Then again, what do engineers know? They build reactors besides the sea in earthquake zones.)

Trouble making moss

First plants caused ice ages: research: New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages.

Land plants came along that late? I need to memorise evolution time lines better. Anyhow, back to the report:

Among the first plants to grow on land were the ancestors of mosses that grow today. This study shows that they extracted minerals such as calcium, magnesium, phosphorus and iron from rocks in order to grow. In so doing, they caused chemical weathering of the Earth's surface. This had a dramatic impact on the global carbon cycle and subsequently on the climate. It could also have led to a mass extinction of marine life.

The research suggests that the first plants caused the weathering of calcium and magnesium ions from silicate rocks, such as granite, in a process that removed carbon dioxide from the atmosphere, forming new carbonate rocks in the ocean. This cooled global temperatures by around five degrees Celsius.

In addition, by weathering the nutrients phosphorus and iron from rocks, the first plants increased the quantities of both these nutrients going into the oceans, fuelling productivity there and causing organic carbon burial. This removed yet more carbon from the atmosphere, further cooling the climate by another two to three degrees Celsius. It could also have had a devastating impact on marine life, leading to a mass extinction that has puzzled scientists.

Rupert Post - The Second

I can't find a link to it right now, but I am sure that I have heard someone, probably former Murdoch editor Bruce Guthrie, explain that Rupert Murdoch's editorial control was not overtly a matter of directing editors what he wants them to run; it is more a matter of Rupert expressing his general feel on an issue, and then newspaper editors doing a "pre-emptive fold" to slant coverage to the way they think Murdoch might approve.

This has been on my mind ever since Rupert took to Twitter, and very early on in the piece, praised Matt Ridley's book The Rational Optimist, which has been most noted for its "meh, climate change probably isn't that big an issue after all" attitude.

I've been waiting for the "pre-emptive fold" ever since, and I take the Wall Street Journal's publishing of a letter by 16 prominent skeptics part of this. (Not that the WSJ ever needed much prompting to run with climate change skepticism.)

Today, I see that The Australia re-prints the letter, just in case people here haven't already heard about it.

Fold, fold away, opinion editors.

And perhaps let someone note that the article is outrageously dishonest in one key section, at the very least:

Nordhaus:

The piece completely misrepresented my work. My work has long taken the view that policies to slow global warming would have net economic benefits, in the trillion of dollars of present value. This is true going back to work in the early 1990s (MIT Press, Yale Press, Science, PNAS, among others). I have advocated a carbon tax for many years as the best way to attack the issue. I can only assume they either completely ignorant of the economics on the issue or are willfully misstating my findings.

UPDATE: for a very detailed take down of the letter, have a look at the Skeptical Science post about it.

UPDATE 2: Andy Revkin, who first publicised Nordhaus' complaint about how the letter misrepresented his views, has another post about the letter, and the rebuttal, which takes a very soft line on the scientists involved. He seems strangely un-inclined to note the lack of expertise in the area under discussion, just noting that "most of the authors in both camps are scientists."

UPDATE 3: I still can't work out where I got "pre-emptive fold" from (maybe a radio interview), but here is Guthrie writing about Murdoch in the context of News Ltd paper's coverage of the Labor government here:

Either way, it certainly wouldn't have been a direction. That's not Murdoch's style. It would more likely have been an observation expressed by him or a lieutenant during or after dinner or at a coffee break between sessions. His editors, better than most at reading the wind, would have noted the boss's latest leanings and applied this knowledge at the first opportunity - many of them would have arrived back in Australia the morning of the budget lock-up. Of course, it would be open to an editor to ignore the boss's preferences, but as I discovered, that can sometimes come at a cost.

Rupert Post - The First

I came across this while looking for something for my next post, but it struck me as very noteworthy in light of the arrest of four Sun journalists last week for (allegedly) making payments to police. Here is Bruce Guthrie, former Murdoch employee, writing last year when the News of the World scandal was on:

IN 1988, while attending a conference of News Corporation editors in Aspen, Colorado, I made the mistake of raising the thorny issue of journalistic ethics. The proprietor, Rupert Murdoch, was not amused.

In short order, Murdoch, who was hosting the session, turned red, then purple, as I repeatedly asked a senior executive from his London paper The Sun whether the publication had any ethical framework. It didn't, the paper's news editor finally admitted. In most media companies that admission might have earned the executive a rebuke. But instead, I copped it, with Murdoch later dismissing me as a ''Fairfax wanker''. (For the record, I wasn't at that point; I became one 12 months later.)...

I left that conference in Colorado more than 20 years ago concerned that Murdoch saw ethics or, at least, the discussion of them, as an inconvenience that got in the way of the newspaper business.

To Murdoch's (waaaaay too late) credit, it is being reported that these arrests have arisen from information News Ltd itself has provided to police. Huh: a boss who telegraphs that ethics is for sooks, then later facilitates arrests for breaching them.

What a man.

Church and the pill revisited

It's hard for people who live in other parts of the world to understand completely the kerfuffle in the US about the Obama administration mandating that US Catholic institutions, such as their hospitals, have to offer employees contraception as part of their work benefits health insurance.

One would imagine that this would not be a problem with Catholics in the US at all - everyone knows that all but a couple of percent of them have ignored the Church's teaching on contraception for the last 40 years. And one of the first commentaries I read on it, a post on a Commonweal blog, strongly supported the decision, emphasising the fact that non Catholic employees of Catholic hospitals should not be limited in their health insurance by what their "boss" considers unethical. It also makes the obvious point that for Catholics themselves, the coverage doesn't mean they are forced to use it. The Bishops of America, with good reason I suppose, have no faith that the laity will follow their teaching.

Yet, since then, what seems remarkable is the number of liberal Catholics commentators who have come out against the decision on the grounds that it is the State forcing the Church to act against its "conscience". It's an interference with religious freedom, according to this view.

First Things notes this with pleasure, and I have to say that I was very surprised to see The Tablet also come out against it.

Look, I see the Church being worried about having to provided certain forms of contraception, such as IUDs which (as far as I know) work by interfering after fertilization. Was it possible for the ruling to have allowed the Catholic institutions to not provide cover for certain kinds of contraception only? The problem is, I guess, when your theology is such that there is debate over whether a pinprick in a condom can make its use "legitimate" in certain settings, you can't expect a lot of compromise over a teaching which has such arcane and counter-intuitive results.

Yet, hang on a minute, is this true (from a comment to a New York opinion piece):

I think it's relevant that it is _already_ required in New York (and several other states) that health insurance coverage include contraceptives (with the same limited church exception provided by the Obama administration), and of course Catholic institutions comply. In particular, the hyperbolic objections of Archbishop Dolan of New York to the Obama administration ruling seem particularly inappropriate, since it appears that institutions under his oversight are already in compliance.

I'm not sure that this is right, given the explanation given in a Washington Post column explaining the sort of compromises the States have come up with:

Under Hawaii law, religious employers that decline to cover contraceptives must provide written notification to enrollees disclosing that fact and describing alternate ways for enrollees to access coverage for contraceptive services. Hawaii law also requires health insurers to allow enrollees in a health plan of an objecting religious employer to purchase coverage of contraceptive services directly and to do so at a cost that does not exceed “the enrollee’s pro rata share of the price the group purchaser would have paid for such coverage had the group plan not invoked a religious exemption.” A New York law has similar provisions.

Talk about your fine lines. The Church doesn't have to directly provide the contraceptive cover, but has an obligation to tell the employee how to get it at the same cost that the Church could have provided under their policy (if I am reading that right.)

Isn't this the same as (for example) a law requiring Catholic hospitals that will not provide abortion to refer pregnant women to where they can get it done? (Speaking of which, what happened about the Victorian law in 2008 which did require exactly that? The Archbishop said Catholic hospitals would not obey it, so what has been the outcome?)

Anyway, this is all part and parcel of the extremely complicated situation with health care funding and insurance in the US. Isn't there a way of separating the health insurance from the employment benefits, and Catholic hospitals can just compensate employees for whatever health insurance package they want?

The Australian system has much to recommend it.

Strange polling

So, all of the new year polls show Labor and the coalition pretty much where they were at the end of last year, with a two party preferred vote of 46 to 54 respectively. Given that you normally expect incumbent governments to pick up a bit during an election campaign, and that you only need to shave 4 percent off the Coalition lead to get back to where we were at the last election, Labor is a difficult but not absolutely impossible position, but of course you wouldn't know that from some of the media coverage.

But the strangest thing about politics at the moment is the standing of both leaders. There is no doubt that Julia Gillard seems incredibly unpopular, particularly amongst anyone over the age of 50. There is also no doubt that there has been widespread acclaim in media commentary since the last election for Tony Abbott as having been successful beyond expectation for the Coalition.

So why is it that in polling, they are both equally disliked, with large net dissatisfaction ratings? This has been the case since November on the Newspolls. Since then, Gillard has also been running as preferred PM by a narrow margin.

I don't think I have heard anyone in the media explaining this. Gillard had her high profile visits late last year, but I would have thought any benefit from those would not last long. Tony Abbott has been "Mr No" on the boat arrival issue very firmly since then, and I suspect that people think he is playing politics on what is too sensitive an issue for games, but I could be wrong.

It's all very curious.

Whales and worms

Where there's a worm there's a whale: First distribution model of marine parasites provides revealing insights

Apart from not finding it particularly flavoursome, I've always been a bit leery of raw fish because of the small risk of getting infected with a nematode.

According to this article above:

Eating infected fish and fish-based products can lead to so-called anisakiasis. This illness often occurs in regions in which raw or semi-cooked fish is traditionally consumed. Symptoms include severe stomach pains, nausea, diarrhea, vomiting and fever, or even severe allergic reactions. Around 20,000 people are affected throughout the world each year, with a growing tendency. Hotspots include the coastal regions of Europe, the USA, as well as Japan and developing countries, in which fish and seafood are an important source of protein.

Interestingly, the nematode can pass through several species, but ends up breeding via those big, loveable whales:

The marine parasites have a complex lifecycle, in which they frequently change host. The final hosts for each species are Baleen and toothed whales (so-called cetacea), which absorb the parasite with their food and act as its host until sexual maturity...

On the way to the whale, fish, cephalopods and crabs act as intermediate hosts for the parasites.

Until we live in a world where whales are given giant worming tablets, like our pet dogs and cats, I'll stick to cooked fish, thanksg

Rain, rain

The weather bureau seems to have predicted levels of rain in Queensland pretty well for the last two summers. Last year, based on high sea temperatures and the strong La Nina, they predicted a very wet summer, and were right. This year, they predicted a pretty-wet-but-almost-certainly-not-as-wet-as-last-summer summer, and it seems to be coming true.

Certain parts of the state are getting some record falls, though:

Senior hydrologist Jim Stewart says records going back to 1884 for the Paroo River have been broken, with extraordinary rainfall totals over the weekend....

THE Gold Coast is smashing January weather records after the big downpour in the Hinterland and the border.

Coolangatta yesterday set a record for January rainfall of 479.6mm, up from 392.8 in 2006.
Springbrook on the wet and wild Wednesday received 291mm, easily breaking the 2008 daily record for January of 265mm.

And I see that over in New Zealand, it's been a particularly wet summer, in parts:

Hardest-hit were Nelson and Takaka, where flooding plagued the region for most of the month causing slips, road closures and evacuations.

Nelson was soaked with six times its normal rainfall, while Takaka had eight times its usual.

Both recorded their highest December totals since records began in 1941 and 1976 respectively, with 446mm of water hitting Nelson and 1103mm pouring down on Takaka.

Takaka also recorded its highest ever one-day rainfall, on December 14, with 392mm flooding the town - beating its previous record of 259 mm recorded in November 1990.

Yet other parts of the country had little rain:

Conversely, the winds caused the southwest to be warm, dry and sunny. Rainfall there was well below normal, Niwa said.

A bit reminiscent of the unusual situation in the US last with Texas in severe drought, but the Mississippi having record floods.

So, it's interesting to note that a recent report on climate change in England predicts that:

Flooding is the greatest threat to the UK posed by climate change, with up to 3.6 million people at risk by the middle of the century, according to a report published on Thursday by the environment department.
The first comprehensive climate change risk assessment for the UK identifies hundreds of ways rising global temperatures will have an impact if no action is taken. They include the financial damage caused by flooding, which would increase to £2bn-£10bn a year by 2080, more deaths in heatwaves, and large-scale water shortages by mid-century.

Note again that the forecast is for more problem flooding, but also water shortages. It's all to do with intensification of the hydrological cycle, a concept the climate change skeptics have trouble acknowledging as having been predicted years ago as part of AGW. Funny how the newspapers seem to provide evidence for it, though.*

* OK, OK, just reading about the odd record being broken in rainfall here and there doesn't prove anything scientifically. No doubt proper analysis needs to be done, and rainfall statistics can be cut and sliced many ways, as can temperature records, so that some "record breaking" figures may not seem so impressive on closer analysis. On the other hand, I am struck by the way some records are being broken by very large margins indeed, and that in particular is what makes me suspect that later analysis is going to prove the intensification of the hydrological cycle, as predicted by climate scientists.
