Switching from coal to natural gas would do little for global climate, study indicates

Maybe the Greens with their distrust of going heavily into gas as a stopgap on the way to completely clean energy have a point after all. It's all very complicated and debatable though, I'm sure.

Fake meat not so palatable

I'm reminded via another blog that lab grown meat has been in the news lately, with an upbeat (more of a beat up, actually, as you will see) article in the SMH with an absurdly misleading headline "how synthetic sausages could be on our plates in six months time."

Err, no.

The report notes the work in the Netherlands that is hoping to make enough lab grown cells to make a hamburger in 6 months time.

People who want to know more about their work should read this interview from the Science Show earlier this year:

Joel Werner: So how long will it take you to produce the mince for a hamburger? I mean, you're talking about small muscle strips, but the hamburger patties I like to eat anyway are relatively large.

Mark Post: Right, so that requires making about 3,000 of these small pieces, and of course that takes time, so we estimate that it will take a year to make that first hamburger, and it will also cost 300,000 euros.....

Joel Werner: So what are the stumbling blocks to reaching that future?

Mark Post: Well, there are a couple of scientific issues, technological issues. One is to get the protein content higher than it is right now, it's now about 70%, and it needs to go up to 90%, 95%. Then there is of course eventually the scaling up of the whole process and quality control, because you don't want these cells to go into a cancer mode or anything like that, so you need to quality control it. And finally we need people to accept the concept....

Mark Post: For many of them it would. We actually spoke to the chairperson of the Vegetarian Society here in the Netherlands and she said, 'I wouldn't eat it because it still requires animal cells, but I'm sure that more than 50% of my constituents will start eating meat.' We still need donor animals to get the adult stem cells. We need a supply of donor animals, but we figure that a factor of 1 million less than we are using right now, and we may be able to improve that even more.

So, let's get this straight: at the moment, they have small pieces of pale, not high in protein, strips of cells that don't taste like meat. (Towards the end of the interview, they mentioned that someone did taste a bit.)

Also, as you still need the stem cells to grow it, vegetarians are still capable of objecting to it.

The other point to note is that, according to another Science Show interview on the topic, you are not likely to have any lab grown meat that resembles a steak any time soon:

....they never tell you when you're a kid that meat is muscle, and if you take a piece of muscle it is not just beef cells. You've got mostly the striated muscle cells, as they're called, which make up the bulk of the meat, probably 85% of it. They are called striated because if you look at the muscle cells under the microscope, each cell grows like a long fibre, like a ladder if you like or like a railway track, because across it are these very, very fine lines, like the sleepers or the rungs of a ladder. And those are the little lines that slide into each other and cause the muscle to contract. Those are the striated muscle fibres...

Robyn Williams: Are you saying that they are so complicated that you can't actually culture them?

Brian J Ford: No, you could culture those as much as you want, but all you are going to get is a culture of striated muscle and that's not meat, that is most of meat but it doesn't look like meat, it wouldn't have the texture of meat, it would be soft and slimy and mushy and slippery because those striated muscle fibre cells are held together in layers of what are called fibrocytes, fibre producing cells. And the fibrocytes produce thin...I don't know, like a cross between a piece of polythene and a piece of tissue paper. You see that kind of tissue when you take a piece of meat and lay it down on the kitchen slab, it's the surface coating of each part of the meat.

Frankly, it sounds like the future of lab grown meat is only going to be in something resembling mince, and even then it sounds like a hell of a lot of work is to be done to make it taste like beef.

It does sound to me like a ridiculously pie in the sky scheme, when you can just kill a cow instead.

One other interesting thing which I had never heard of before from that interview with Ford is this:

...it was in 1976 in a book called Microbe Power that I said how in a few square miles of countryside one could actually produce enough microbial protein to feed the entire world. That is true, and it has almost become true because...I don't know whether quorn is particularly popular in Aussie?

Robyn Williams: It is not necessarily so.

Brian J Ford: It's a vegetable protein which is very popular in England and now very popular in the United States as well, and it's produced by taking a fungus, which was originally discovered growing on barley in a field in the midlands of England about 30 or 40 years ago, and you grow this fungus so that it produces a sort of a rubbery, chalky mass which you then texturalised to be like meat, you add flavours to it to make it taste like meat, you mince it up or chop it into little cubes so that it looks quite like meat, and it is used as a substitute for meat.

This is grown in factories, and it seems to me to be very paradoxical, this. Quorn is particularly popular amongst natural food addicts, people who are vegetarians and others love quorn.

And here I'd never heard of it before. But Googling around, and it looks like Quorn based products are indeed available in Australia.

So we apparently already have a vegetarian based "fake meat" that is apparently better tasting than soy based products, and it could easily supply the world's protein needs? If anything, Quorn sounds like a much better solution to the "feed the world" issues that lab grown meat are fancifully suggested as answering.

I'm going to go looking for Quorn when next near a health food supermarket.

Bad news for Queensland

NOAA’s Climate Prediction Center: La Nina is back

La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter. Today, forecasters with NOAA’s Climate Prediction Center upgraded last month’s La Niña Watch to a La Niña Advisory.

BBC News - Drunk Swedish elk found in apple tree near Gothenburg

Apparently:

Drunken elk are not an uncommon sight in Sweden during autumn, when there are plenty of apples about.

Other residents of Saro had seen the elk on the loose in the preceding days.

Mr Johansson said the elk appeared to be sick, drunk, or "half-stupid", the Associated Press reported.

Record smashed

Only In It For The Gold: Daily Rainfall Record Exceeded By 60%

Michael Tobis notes (from Weather Underground) an extraordinarily record breaking amount of rain in one hit that happened the other day in the US:

An extreme rainfall event unprecedented in recorded history has hit the Binghamton, New York area, where 7.49" fell yesterday. This is the second year in a row Binghamton has recorded a 1-in-100 year rain event; their previous all-time record was set last September, when 4.68" fell on Sep 30 - Oct. 1, 2010. Records go back to 1890 in the city.

Tobis asks:

Have we been underestimating the extent to which climate change will drive extreme events?

All further grist to the mill of my recent comments that extreme flooding events may well be the most damaging, expensive and convincing early sign that future AGW induced climate change is not something you can easily adapt to.

A helpful article

Dessler Demolishes Three Crucial 'Skeptic' Myths

People who follow the AGW science issue would all know about the fight going on at the moment between the recent Spencer & Braswell paper and its apparent rebuttal by Dessler.

I've been finding the technical arguments over this to be very hard to follow, but Skeptical Science does a pretty good job at making it more understandable and noting its general importance for what are (as SS notes) the only two recent articles by skeptical scientists that argue for a very low climate sensitivity.

It is important to read the comments too: Spencer thinks he found an important error in Dessler; it seems that the error, if it's there, is not as big as Spencer claims.

Nude in Jerusalem

I found a rather interesting review of a book at First Things about how Christians should respond to homosexuality, followed by a very long thread with lots of interesting points and arguments on the topic. (I haven't read them all.)

The article does a good summary of the common argument by more liberal Christians as to why even New Testament scriptural condemnation of same-sex behaviour can be ignored in the modern world. I'll extract it here:

Jewish antipathy toward same-sex behavior in the ancient world, according to Selmys, was based on a perception that homosexual relationships were abusive. Selmys describes Greek homosexuality as pederasty. Greeks openly praised love of boys, an older lover and a younger (preferably beardless) beloved. It was mentoring, with sexual dividends for the mentor. So when Seleucid Greeks erected a gymnasium in Jerusalem, recounted in Second Maccabees, Jews were right to be alarmed. The no-clothing policy at the gymnasium provided not only a way for the Greeks to easily identify practicing Jews by their circumcision, but also an opportunity for Greek men to ogle Jewish boys.

Homosexual behavior was also part of ancient Rome, but the Romans, being Roman, skipped the idealism and went straight for virile conquest. Homosexual behavior was tolerated, if one was the dominant participant. The passive role, a decidedly less than virile position, was filled by a slave or by a social inferior, or someone looking to move up the career ladder or someone too intimidated to snub the offer.

Christians inherited the Jewish antagonism toward same-sex behavior. “Sodomy was implicitly connected with sexual predation in the minds of the late Roman, Byzantine, and medieval Christians,” Selmys writes. “This needs to be taken into account when reading the vitriol that is poured out against ‘sodomites’ in the writings of early Christians”—St. Paul included.

The part that I thought most post-worthy was the bit about the Greek gym in Jerusalem. I have a vague recollection of reading something about that before, but it's worth looking into. [Now there's a Two Ronnies double entendre for you, Jason!]

Google quickly turned up a paper by someone from the University of Pisa that's actually called "A Gymnasium in Jerusalem", although most of it is generally about the Hellenization of Palestine. It's pretty interesting. On the gymnasium itself, it notes:

II Maccabees specified that the construction was located near the acropolis of Jerusalem. In general, a gymnasium was an outdoors complex, open to the public at large, and provided space dedicated to sports and cultural activities. A standard gymnasium included a running track, a place for gymnastics, one or more swimming pools, dressing-rooms and other minor buildings...

In ancient Greek the word gymnos (from which gymnasium is derived) means naked, and every participant competed naked. Thucydides, who wrote in the 5th century BC, stated that in Asia this was not the rule, but he referred to an earlier period (8th century BC) and affirmed that barbarians could hardly be expected to follow such Greek customs. However, it is most likely that, following Alexander the Great and his conquests, the situation could have changed.

Most of the young competitors belonged to an association known as the ephebia. This organization included young males between 18 and 20 years (ephebes), who were trained in the use of weapons and prepared for public life. The ephebes were young citizens skilled in war who wore short hair, a little cloak and a petasus, a sort of large hat in order to protect them from the sun. The gymnasium thus served as a training ground for them. But it also had another role: it was considered the defining institution of Greek urban civilization, serving as the ideological and cultural centre of the city.

The gymnasium was the focus for social activities and provided education in writing, literature, and rhetoric. Therefore, the introduction of the gymnasium represented a set of wholly new values for the Jews.

....The gymnasium provoked opposition in Jerusalem because it featured naked competitors. Although the sources do not mention this directly, the various references to circumcision, especially in II Maccabees, may be read as indirect proof. According to Jewish tradition nakedness was looked upon as offensive. This attitude not only reflected moral beliefs. It also highlights the importance that the Jews attached to clothing and specific kinds of dress. Within the Jewish cultural tradition clothing took on specific roles and functions, including its ability to distinguish various categories of persons: the rich from the poor, the religious from the laity, leaders from their supporters. It seems the nakedness of the gymnasium represented a sort of equality in a society that was structured in a strongly hierarchical way. Moreover, Jewish males had serious problems with nakedness because of their circumcision. The Greeks regarded circumcision as an insane and shameful mutilation of the human body. For that reason, Jewish people suffered from their awareness of this physical difference, which sometimes led to mockery by others.

Someone at a Mormon site notes:

The Greeks did their athletics in the nude. The gym in Jerusalem could actually be seen from the temple and the site of men wrestling in the nude was very offensive.

The University of Pisa article I cited at length goes on to note:

The Jews who willingly took part in Greek culture used various strategies to hide their circumcision. The main method was a sort of operation (epispasmos) in which circumcision was disguised by an artificial foreskin. This practice began following Jason’s request to Antiochus IV. It is also probable that during Antiochus IV’s time in Jerusalem the epispasmos was embraced by more conservative people, who feared king Antiochus IV’s hostility toward Jewish traditions.

For those so inclined, there's a whole article about the epispasmos operation on the website of a modern nuttily obsessed anti-circumcision site here. I liked this line:

At a time before effective anesthesia, a man inclined to try this procedure had Celsus' assurance that it was "not so very painful."

Anyway, it's all rather intriguing to think that perhaps the effects of nude athletics in Jerusalem (including even where the gym was built) more than 2000 years ago can still have cultural influence today. (It's also odd to realise the anti-circumcision movement has been around a long, long time.)

Political punditry gone insane

I cannot believe what I am reading in the media and on the blogs at the moment re suggestions for Federal Labor to improve its position.

And no, I'm not talking right wing blogs full of ratbaggery: they just want to have an election and aren't about suggesting what Labor can do, unless it's something facetiously self serving, such as Andrew Bolt's call for a new leader who should drop the carbon tax. (In a sign of desperation, Bolt has taken to calling for a new leader to replace Gillard within a week or so, before the carbon tax legislation is introduced to Parliament.)

It's the Left leaning commentary that has gone insane. Firstly, there's old Phillip Adams calling for Kevin Rudd to be re-instated as leader. I don't hold his political punditry in high regard anyway, but his failure to see through the flim-flammery and flakiness of much of what Rudd did in the first year is typical of some on the Left. He seems to think Rudd is an intellectual powerhouse: I think most objective people see shallowness whenever he tries to show his smarts.

But even someone who generally writes intelligently and in a moderate voice, like John Quiggin, has given up on Labor having any chance under Gillard, and suggests she gets the carbon tax through and then resign for the good of the Party. Yeah right: she finally gets a big and difficult reform through Parliament, and she should say "well, people don't like me, so I'm off." I just can't fathom the logic of this. Quiggin suggests that while he didn't used to think Rudd should replace her, he thinks he is acceptable now, due to his having "more credibility"on the asylum seeker issue (!). This is just nuts, if you ask me. And as with all people suggesting a graceful Gillard departure, it's not as if they can point to an obvious successor.

Even more bizarre are some of the comments on the Lefty blog Larvatus Prodeo, where Kim takes essentially the same position as Quiggin, and many in comments agree. Fran, who actually can hold her ground in arguing about a carbon tax, goes as far as to write this insane bit on Gillard:

I didn’t respect her before she took the job and her appearance as the candidate of the mining thugs only served to lower my already poor impression of her. Throw in attacks on The Greens as entitled latte-sipping alarm-clock ignoring intellectuals and Gillard is Bolt in drag. The roll out of “people smugglers’ business model” ad vomitus gets her the unremittingly egregious tag. The only thing positively distinguishing her from Abbott is that at the margins, The Greens still exercise some restraint on her regime. Without that, I’d watch the government go over the edge of the abyss and spit on them on the way down.

In the papers, the moderate Mumble blog gets the analysis right:

We’re in a strange place. If this federal government announced it was erecting a new set of traffic lights*, local businesses would protest, residents would fret, petitions would be signed and convoys embarked upon.

MPs in Western Sydney would report that the issue was killing them—and Graham Richardson would agree.

These are odd, but special, political times. Yes it’s the policies a bit, but more than that is a dysfunctional dynamic.

But then suggests:

Could a new leader, perhaps after the passage of the carbon legislation, quarantine the Greens and generate some authority?

It’s probably worth a try.

No, it's not.

The essential problem for Labor has been its flip flopping on key issues that have made it look weak and indecisive; but conversely, those things in which it has sought to act quickly have sometimes come out looking too rushed, ineffective or just flakey.

There is no way that replacing Gillard with a new leader is going to address these core issues. In fact, it will exacerbate them.

Getting through a carbon tax, the mining tax, and finding a workable asylum seeker policy will go a long way to fixing the problems. It's absurd to think that, as this fundamental "fix" starts to happen, the PM should resign.

One of the comments at Mumble blog gets it right, I reckon. If anything, Gillard would improve by sounding tougher, not just with Abbott but with her appalling bunch of sleazy media critics, and those in the public (even those Labor sympathisers who are telling her to go). Here's the comment, from "Balmain":

Mumbles, I keep saying the same thing and you keep saying the opposite...but do you honestly, truly believe that the electorate will tolerate yet another leadership change? I can see Gillard becoming our answer to Thatcher (I hate to draw parallels based on gender..), but I can’t see any other way back for the government. They will not be able to run on their record (once again) if they lose her, and that will make for yet another disastrous campaign. If they hold tight and the country is in good stead come 2013, they will have a much better story to tell than “we’re sorry, we stuffed up and lost our nerve again”. It requires nerves of steel from the ALP, but if they have it surely it’s their best hope? I’m not saying Gillard will be liked, but if she can campaign on successful introduction of major policies by 2013 despite blatant adversity, there will be a begrudging respect factor, surely. I have noticed that a bit of media coverage lately, whilst mostly slating the government, has begun to make frequent mention of her incredible stoicism in the face of all this. It could be starting already…

He's right.

Of course, there are good reasons for fearing the Australian economy, which virtually every economist (save perhaps for the dropkick Sinclair Davidson - hey, he's called me much ruder names at his own blog) would agree has not been fundamentally mismanaged by this Labor government, will soon go through another set of trying times if there is another international financial crisis, and Labor will unfairly wear the blame for this. But this is the fate possibly awaiting any Labor leader, new or old, and replacing Gillard is not going to help that.

UPDATE: This post makes me sound like a complete convert to Labor and can't find a thing to complain about Gillard. Well, there is pretty strong evidence that she was behind the flip-flopping on what to do about a carbon price under Rudd, but as far as those who want to see one in are concerned, actually getting one through Parliament (and, it would appear, a better one than what Rudd nearly got through) should remedy that. On asylum seekers: well, that's a very difficult one for Labor, and no leader is going to find that a breeze to manage.

But if the Coalition would drop its stupidity on climate change, accept a mining tax is a legitimate thing to pursue, and install Malcolm Turnbull as leader, I would be happy to vote for them again. Otherwise, who knows, I might even vote Labor next time.

My other point about our PM which I made reference to a few days ago is that I honestly think that to improve her image for decisiveness, as well appear better to Asian leaders, she should just marry Tim. Don't make a big song or dance about it: just release one set of photos and do it in the gardens of the Lodge. Make sure Kevin Rudd attends!

At home with At Home

I didn't have high hopes for At Home with Julia, the short run sitcom based on an "re-imagining" of the life of our Prime Minister and her de facto partner.  However, I have to say I enjoyed it.

Of course, it's absurd to paint the Lodge as just a big house in which the PM or her partner have to cook their own dinner every night, and seemingly can only afford one hired help during the day.  But hey, it's just carrying on the tradition of movies which paint what's surely a ridiculously scaled version of the actual busy-ness of official residences.  (I thought Love Actually was particularly bad in this regard.)  

But the thing I did really like about it was the caricatures of  other politicians - the Paul Keating on the speaker phone droning on bitterly about what happened in 1995 was particularly funny, and although I'm sure the Rob Oakeshott prissiness about what to drink after dinner was unfair, it also amused me. 

I agree with the SMH video review - the best part of the humour was in these minor-ish details.

The actors who played the roles (including just the voice roles) did a piece on Radio National this morning, and it was quite funny.   Go have a listen at the audio link here (not the video, which is just a promo for the show.)

The psychedelic mouse

Did the use of psychedelics lead to a computer revolution?

Well, there are many things I didn't know in this Comment is Free article from The Guardian. (Why don't they put the best CiF articles on the main page like they used. I often forget to check it now.) Anyway, here are the most surprising bits:

...as New York Times reporter John Markoff told the world in his 2005 book, What the Dormouse Said: How the 60s Counterculture Shaped the Personal Computer Industry, Jobs believed that taking LSD was one of the two or three most important things he'd done in his life. That 2001 conversation inspired Markoff to write the book: a history of computing with the drugs kept in.

From 1961 to 1965, the Bay Area-based International Foundation for Advanced Study led more than 350 people through acid trips for research purposes. Some of them were important pioneers in the development of computing, such as Doug Engelbart, the father of the computer mouse, then heading a project to use computers to augment the human mind at nearby SRI. Grim also names the inventors of virtual reality and early Cisco employee Kevin Herbert as examples of experimenters with acid, and calls Burning Man (whose frequent attendees include Google founders Sergey Brin and Larry Page) the modern equivalent for those seeking mind expansion.

Well, if the idea of the computer mouse came up during an acid trip, it could well have started out as literally a mouse, if you follow my drift.

The article also notes a West Coast/East Coast theory of computer development, which I hadn't heard of before either:

Markoff traces modern computing to two sources. First is the clean-cut, military-style, suit-wearing Big Iron approach of the east coast that, in its IBM incarnation, was so memorably smashed in the 1984 Super Bowl ad for the first Apple Mac.

Second is the eclectic and iconoclastic mix of hackers, hippies, and rebels of the west coast, from whose ranks so many of today's big Silicon Valley names emerged. Markoff, born and bred in the Bay Area and 18 in 1967, argues the idea of the personal computer as a device to empower individuals was a purely west coast idea; the east coast didn't "get" anything but corporate technology.

Sounds kind of plausible.

The neighbourhood might be dangerous

Our galaxy might hold thousands of ticking 'time bombs'

A couple of astrophysicists have come up with an idea as to another mechanism which may be the precursor to supernovas, and suggest this:

"Our work is new because we show that spin-up and spin-down of the white dwarf have important consequences. Astronomers therefore must take angular momentum of accreting white dwarfs seriously, even though it's very difficult science," explained Di Stefano.
The spin-down process could produce a time delay of up to a billion years between the end of accretion and the supernova explosion. This would allow the companion star to age and evolve into a second white dwarf, and any surrounding material to dissipate.
In our Galaxy, scientists estimate that there are three Type Ia supernovae every thousand years. If a typical super-Chandrasekhar-mass white dwarf takes millions of years to spin down and explode, then calculations suggest that there should be dozens of pre-explosion systems within a few thousand light-years of Earth.
Those supernova precursors will be difficult to detect. However, upcoming wide-field surveys conducted at facilities like Pan-STARRS and the Large Synoptic Survey Telescope should be able to spot them.

Well, how dangerous could a Type Ia supernova be?  According to Wikipedia:

Type Ia supernovae are thought to be potentially the most dangerous if they occur close enough to the Earth. Because Type Ia supernovae arise from dim, common white dwarf stars, it is likely that a supernova that could affect the Earth will occur unpredictably and take place in a star system that is not well studied. One theory suggests that a Type Ia supernova would have to be closer than 10 parsecs (33 light-years) to affect the Earth.[8] The closest known candidate is IK Pegasi.[9] It is currently estimated, however, that by the time it could become a threat, its velocity in relation to the Solar System would have carried IK Pegasi to a safe distance.[5]

Maybe we'll be OK after all.

Harry on carbon pricing

Australian Carbon Pricing - Harry Clarke

Economist Harry Clarke went to a meeting recently that was looking at carbon pricing, and made many interesting observations about the forthcoming Labor scheme.

One point about Tony Abbott's direct action plan which I had not heard raised before was this:

Birmingham claimed that because those direct actions were to be monitored on the basis of effectiveness and cost that the Liberal approach was market-related but missed totally the core point about the informational efficiency of prices in a setting where you want to change the behaviour of millions of agents. Certainly an army of bureaucrats will be needed to implement the Liberal policy which ironically seeks to make cuts in the climate-related bureaucracy.

Harry Clarke is satisfied generally with the the Labor scheme is " a remarkably successful first attempt by government to come to grips with the issue of climate change." He acknowledges it is not perfect, but in such a complicated and difficult area, I think he would say that that is hardly a surprise.

Harry used to visit and argue with the relentless and (frequently) ill-informed commentary at Catallaxy on climate change and carbon pricing. He appears to have given up out of frustration, and who can blame him.

I am pleased to see that the government is planning on getting its carbon scheme legislation introduced into Parliament as early as next week. The army of ill informed people who have been sucked in by the completely ill informed and/or dishonest right wing media figures such as Andrew Bolt, Alan Jones, Michael Smith and Jonova are going to tire of their campaign when the legislation goes through, and the Gillard will at least be able to point to one difficult issue in a decisive way, at last.

More artificial reproductive stupidity

One Sperm Donor, 150 Sons and Daughters - NYTimes.com

Yes, one sperm donor in the States had been the father of 150 kids, and apparently there are many cases of 50 or so from the same donor. As the article notes:

Critics say that fertility clinics and sperm banks are earning huge profits by allowing too many children to be conceived with sperm from popular donors, and that families should be given more information on the health of donors and the children conceived with their sperm. They are also calling for legal limits on the number of children conceived using the same donor’s sperm and a re-examination of the anonymity that cloaks many donors.

“We have more rules that go into place when you buy a used car than when you buy sperm,” said Debora L. Spar, president of Barnard College and author of “The Baby Business: How Money, Science and Politics Drive the Commerce of Conception.” “It’s very clear that the dealer can’t sell you a lemon, and there’s information about the history of the car. There are no such rules in the fertility industry right now.”

Although other countries, including Britain, France and Sweden, limit how many children a sperm donor can father, there is no such limit in the United States.

Sleep your way to evolutionary success

Researchers seem to have a lot of interest in the sex lives of early humans.  Hot on the heals of the story last week that sleeping with Neanderthals had been good for our immune system, there's another story today of early homo sapiens sleeping with other homo-something-or-others which are no longer around:

Hammer and his colleagues argue that roughly 2% of the genetic material found in these modern African populations was inserted into the human genome some 35,000 years ago. They say these sequences must have come from a now-extinct member of the Homo genus that broke away from the modern human lineage around 700,000 years ago.

Hammer says this disproves the conventional view that we are descended from a single population that arose in Africa and replaced all other Homo species without interbreeding. "We need to modify the standard model of human origins," he says.

 Well, I suppose there was no TV in those days, and staring at the cave wall paintings was entertaining for only so long.

The right thing to do….

So that's where it goes

Extreme Flooding In 2010-2011 Lowers Global Sea Level

I find this surprising: it appears that the down bumps on the road to rising sea levels can be accounted for (at least in the last year) by the large scale flood which have happened around the world.

All the water will get back to the ocean, eventually.

It still seems to be that more frequent, larger scale, flooding, might well be the worst, early effect of global warming that AGW proponents did not really spend enough time warning people about.
