### IPCC: climbers magazine, student dissertation in, sex novels out

The U.K. Times have found out that Rajendra Pachauri was directly lying when he claimed that he had only known about the wrongness of the Himalayan statement for a few days. In fact, he had known the truth for months - and I would guess that almost certainly for years.

By the way, the IPCC boss uses a car with a driver to drive to his office (1 mile).

Greenpeace used a specific scientific method to estimate the melting of the glaciers. The scientists above figured out that the ice was melting beneath their feet. Picture: Spencer Tunick

Meanwhile, The Telegraph found out that the statement about the Himalayan glaciers was actually one of the more scientifically supported IPCC claims.

### A subtle sentence on extinctions

Many reports suggest that there may be 2,000-3,000 members of the giant panda clan in the wild which would mean that they should be classified as "vulnerable" rather than "endangered" (which is more serious). But there clearly exist pressures to keep these nice symbols of biodiversity "endangered".
Andrew Revkin wrote a couple of words about the IPCC Himalayan glacial scandal. But there's another interesting story in his text - one about a prediction of extinctions. If you open the Fourth IPCC Synthesis Report (PDF) on page 48 (26 of 52), you will find the following bizarre quote:
Approximately 20 to 30% of plant and animal species assessed so far are likely to be at increased risk of extinction if increases in global average temperature exceed 1.5 to 2.5°C (medium confidence).
The comment "medium confidence" simply means that the probability of the sentence's being correct is around 50% - as explained on page 27 (5 of 52). Because the sentence is thought to be equally likely to be right or wrong by the author, you should ignore it. That's the only way to interpret "medium confidence".

Revkin also explains that the 1.5 °C or 2.5 °C warming is meant to be relatively to the 1980-1999 mean.

### UAH MSU projection: January at 0.67 °C

After 20 out of 31 daily UAH data (less than 2/3) for January 2010 became available, The Reference Frame expects and predicts the final January UAH anomaly (for channel 4, near surface) to be 0.67 °C plus minus 0.03 °C which will be 0.39 °C warmer than December 2009 (anomaly-wise).

The final figure will be found in two weeks at the bottom of this page, right after "2010 1".

Almost certainly, that will make it the warmest January on their record, ahead of 0.59 °C in January 2007 and 0.58 °C in January 1998.

However, the cooling in recent days - which may be related to the melting snow's latent heat's cooling of the atmosphere - will almost certainly prevent January 2010 from beating the two tied leaders - February 1998 and April 1998 - when the anomaly was 0.76 °C. May 1998 is the current holder of the bronze medal for its 0.65 °C and January 2010 is "more likely than not" to take over. We will see.

By the way, so far, the 4th and 5th places - which will become 5th and 6th warmest months of the UAH record - belong to January 2007 and January 1998 we mentioned previously.

### The rise of populist pseudoscience

Nothing against the ordinary people in general I think it's fair to say that at least 95% of the population has no clue about modern physics.

Many people have been taught to uncritically "okay" the kind of science that is taught at schools - which is usually correct, at least morally. But whenever you seriously investigate what they really think, deeply in their souls, about the "right" laws of physics to be found, you find out that

### IPCC: apology for glaciers, is that enough?

The IPCC has issued a statement,

IPCC statement on the melting of Himalayan glaciers
that CNN calls an apology. See other news outlets. They regret the "poor application of well-established IPCC procedures."

Well, I think that this statement is extremely tendentious because they use it to re-iterate the mostly irrational alarm about the glaciers - now, admittedly, without any numbers.

Moreover, all of us know that the "well-established IPCC procedures" are designed to achieve exactly these things - statements and numbers that are scientifically unjustifiable or that don't fairly reflect the underlying research but that are useful for the promotion of their main and predetermined conclusion, namely that climate change is something to worry about.

The newest statement is just another example of this fact because even though the scientific evidence has been shown to be non-existent, they don't want to change anything about their alarmist preconceptions.

### Massachusetts grabbed by the elephant

Massachusetts: Brown vs Coakley

Click to zoom in. I spent some time by drawing it. ;-) The actual map of the results looks even more like an elephant, with a blue eye (in Boston).

So is it a donkey or an elephant? While it doesn't look fat enough for a proper elephant, this Cape Cod piece surely does look like a proboscis, doesn't it? The voters are solving a homework problem whose answer used to be clear but it is fortunately no longer quite clear.

Massachusetts is deciding between Martha Coakley (DEM) and Scott Brown (GOP). Update: Brown defeated Coakley, 52 vs 47, great! Cambridge voted the wrong answer, 84 vs 15 for Coakley: you won't find a similarly heavy distortion elsewhere.

### 13 °C of warming would be fine for life

People have been brainwashed by the climate hysteria for years. So it's not shocking that many of them began to uncritically repeat many of the misconceptions. Nevertheless, I am always surprised by the lack of independent rational thinking - even when it comes to the people who are expected to be sensible.

A first book about the ClimateGate is available at amazon.com: click the icon to buy (after several more clicks and choices)
For example, let's ask what is the temperature change - the change of the global mean temperature - that would threaten the existence of life as we know it. By this statement, I mean an existential threat for humans and/or most of the species we know today.

I find it completely obvious that something like 13 °C of warming (10 times the change expected in the next 100 years, even if we extrapolate the recent 30 years) would not constitute such a threat. The most important picture in this discussion is the following map of the annual mean temperatures:

### IPCC vs Pachauri: 2035 vs 2350

The Sunday Times, AFP, WUWT, and others inform that the IPCC is likely to confirm a criticism from a recent Indian government report, retract a statement that the Himalayan glaciers are likely to be gone by 2035, and disagree with a railway engineer who said that India was arrogant to doubt that the glaciers will be gone by 2035. That wouldn't be extraordinary if the railway engineer were not the IPCC boss.

The basic points about the scientific origin of the figure "2035" are now well understood. In 1999, an unknown Indian scientist listened to the song above which is an Indian variation of The 12 Days of Global Warming. He got kind of obsessed with the numbers and with the Indian culture and he calculated the date of the demise of the Himalayan glaciers. Using the song above, he got the following seemingly sensible result:

### Warming induced by the latent heat of snow

According to UAH, January 2010 will almost certainly be their warmest January on record, and by its anomaly (which is likely to exceed 0.70 °C), it will be one of the 4 warmest months.

Recent NASA MODIS pictures of the United Kingdom look like an ice age.

I was thinking how it was possible that such an unusually cool January is so warm according to this global methodology. Snow was almost everywhere on our hemisphere, wasn't it? Well, it may actually be a reason.

### Exponential percentages: a useful proposed terminology

Imagine that the price of something increases by 25%. Later on, the price returns to the original value. How much did it decrease? Well, someone could say 25%. But it dropped by 20% only because you must count the percentages from the new, higher price.

### Karel Čapek: 120th birthday

Czechia is arguably the only country in the world where Google is very far from being the #1 search engine.

Seznam.cz ("The List"), founded by a guy whom I used to know from a Bulletin Board Service (and from a real-life BBS Session), is well ahead of Google. In fact, many Czamazechs who don't know how the Internet works inside still can't quite distinguish "Seznam" from the "Internet". :-)

(OK, Baidu beats Google in China, 77% vs 17%, about the same margin as Seznam vs Google.CZ. Thanks, Jorge.)

So you should visualize Czechia as a parallel Universe where a local Yahoo clone (with directories) actually survived as the winner, and adopted the standard search format before it was crushed by a pure search-based competition.

By the way, Mr Ivo Lukačovič, the founder of Seznam.cz, could have sold the company for USD 1 billion in 2008. He refused: I suspect that they no longer offer the same amount. ;-)

Not too surprisingly, Google is trying to earn the love of the Czech Internet users. National themes are a part of the game. The Doodle on the Czech Google today is the following picture:

Yes, Dr Karel Čapek, a top Czech 20th century writer, was born exactly 120 years ago, on January 9th, 1890, in Malé Svatoňovice, a village in Eastern Bohemia, Austria-Hungary. He died in Prague in 1938, at the age of 48+ years.

### The 248-dimensional heterotic E8 symmetry built in the lab

Radu Coldea and 8 co-authors have made some interesting experiments and they just published a neat paper in Science:

Quantum Criticality in an Ising Chain: Experimental Evidence for Emergent E8 Symmetry (abstract)

### Snow density and water equivalent

In 2000, East Anglia's CRU determined - for hundreds of millions of pounds of taxpayers' money - that snowfalls are now just a thing of the past. Children wouldn't see snow again.

Meanwhile, in the real world, snowing just returned to Pilsen (not to speak about a large part of the Northern Hemisphere); the temperatures have remained below the freezing point for many days. Up to 60 centimeters - two feet - of snow is forecast in the Czech Republic until Monday while frozen iguanas fall from trees in Florida.

How much water is 60 centimeters of snow? Of course, if the snow melts, the water occupies a smaller volume.

Well, each column of H2O is expanded by the same factor. So the depth of snow is equal to N times the equivalent amount of liquid precipitation. How much is N? It depends on the temperature:

• -2 to +1 °C (28-34 °F): N=10
• -7 to -3 °C (20-27 °F): N=15
• -9 to -8 °C (15-19 °F): N=20
• -12 to -10 °C (10-14 °F): N=30
• -18 to -13 °C (0-9 °F): N=40
• -29 to -19 °C (-20...-1 °F): N=50
• -40 to -30 °C (-40...-21 °F): N=100
Minus fourty degrees is a nice place to stop because it's exactly the same temperature in Celsius and Fahrenheit degrees. ;-) You see that N=100 at the coldest temperatures is impressive: a very fine snow, indeed. Finland with its -37 °C should be able to see this amazing coefficient in reality.

### UK Met Office boss: failed predictions, huge salary, grilled, failed

The U.K. Met Office has incorrectly predicted a BBQ summer 2009, mild winter 2009/2010, and the boss - John Hirst - has collected performance-related bonuses that have put his salary above that of prime minister Gordon Brown. Well, BBC has asked some obvious questions:

See the video at the BBC website.

As expected, we couldn't get any coherent answers. There aren't any. At least, we have heard that despite complete failures in predicting anything about the weather for the next season, they're the best ones in the world in predicting the climate in 2050.

Well, it's probably not that hard to be the best among a particular group of pseudoscientific hacks - and the British taxpayers are foolish to pay this guy a salary - even the highest public job salary in the country.

### Gravity as a holographic entropic force

In a new preprint, Erik Verlinde extends some classical visions of Jacob Bekenstein from the 1970s and argues that Newton's force of gravity may be derived as a thermodynamic force trying to maximize entropy. His derivations may look excessively heuristic to many of us, but they're very interesting and thought-provoking. Here is an independent review.

In biophysics, one often deals with long molecules. They tend to "fold" and occupy a small volume because it is entropically favored: there are many more microstates where the molecule is "short". However, molecules will be pushed by a force "F" towards a smaller perimeter "x" only when the temperature is nonzero:
F Δx = T ΔS
Verlinde is trying to construct an analogous derivation of Newton's gravitational force. I will use in the "c=hbar=k=1" units where "k" is Boltzmann's constant. Because of its special role, "G" won't be set to one. At the beginning, "G" will be defined as the coefficient from "S=A/4G", the Hawking-Bekenstein entropy for a holographic screen (no gravitational bulk effects yet!).

### Is science and experience the same thing as "cognitive bias"?

Sabine Hossenfelder wrote another text showing her confusion about some very basic philosophical principles of science in general and physics in particular.

Every time she writes something new, I am amazed how my previous expectations about the most trivial thing about physics that can still be murky to some people are surpassed by yet another record. Last time, she presented her opinion that naturalness - and therefore the dimensional analysis - have no room in physics. There's no reason to expect unknown dimensionless parameters to be of order one, she still thinks.

Needless to say, dimensional analysis and estimates based on naturalness belong among the most paramount methods of physics if not all of science and rational thought. The areas of squares, triangles, disks, and all sufficiently non-singular surfaces of diameter D scale like D^2: they are equal to D^2 multiplied by a number of order one.

### Czech Catholic boss: why Europe is threatened by Islam

Yesterday, Czech cardinal Miloslav Vlk - who is soon to be surpassed either by Jan Baxant or Dominik Duka - answered 24 questions in an interview.

He described his views on the life of Christians before and after the fall of communism; some of his unsuccessful plans for a religious awakening in Czechia; the secularization of the life; interactions between Czechia and Europe; his unsuccessful papal candidacy; idiosyncrasies of individual Popes; integration of Christian churches; the interactions with judaism and the influence of some Jewish thinkers on him.

However, his most widely cited answers were concerned with the expansion of Islam in Europe. See Google News.

### Public support for AGW plummets after ClimateGate

The National Post offers some of the newest, December 23rd, 2009 numbers coming from Angus Reid quantifying the belief of the key native English speakers (US, UK, CA) in various parts of the climate change orthodoxy.

First, people are hopeful that no binding treaty will arise from the Copenhagen Accord. Will there be a binding treaty?

USA: 19% Yes vs 37% No
BRI: 16% Yes vs 43% No
U.K.: 12% Yes vs 44% No.

The rest is undecided. The "Yes" percentage is higher among warmists - around 25% vs 10% for the skeptics. The evolution of the scientific opinions about AGW between November 2009 and December 2009 (written as Nov ⇒ Dec) may reveal the fingerprint of ClimateGate although the decline couldn't have been hidden already for several years. Is man-made global warming a fact?

### Avatar: blue smurf racist propaganda done right

Avatar, James Cameron's new movie (he has previously created things like the Terminators and Titanic), has become the fastest movie ever that has surpassed the USD 1 billion dollar threshold. I watched it tonight (in English - and with Czech subtitles which are still helpful for me at some points). And it's a pretty impressive piece. I will begin wit a ton of spoilers and end up with some comments about politics.

Spoilers

A terrestrial corporation with a lot of soldiers needs some important minerals from a jungle in Pandora near Alpha Centauri - over 4 light years from the Earth. As you can see, people needed to travel by speeds exceeding c/30 if they got there by the year 2154 when this movie takes place. ;-)

### TRF's 20-day-old UAH temperature estimate exactly confirmed

On December 19th, I calculated the UAH December 2009 anomaly to be

0.28 °C,
plus minus a small error, as the sum of the 2009-2008 temperature differences averaged over the known days (Dec 1st - Dec 17th), plus the known final December 2008 anomaly (0.18 °C) - an algorithm that had previously been proven very successful.

You might have said that it was a bold prediction because the figure was 0.22 °C cooler than the 0.50 °C anomaly measured in November 2009.

Roy Spencer at WUWT just reported the final December 2009 UAH global temperature anomaly. Guess how much:
0.28 °C
That's right: TRF can get a better than 0.01 °C accuracy for the final temperature of a month in the middle of the same month. Read TRF to learn the truth weeks, and sometimes centuries, before others. :-)

This also strengthens the validity of the UAH rankings of 2009.

### Interesting hep-th papers

Today, there are 69 new entries on hep-th: 27 of them are new papers. That's a lot and I will surely omit some interesting ones. Nevertheless, this is my selection:

Hořava-Lifshitz theory violates equivalence principle

Amir Esmaeil Mosaffa tries to write the action for particles moving through the Hořava-Lifshitz spacetime. He finds out that not one mass parameter but two mass parameters "M,m", are needed. As a result, the trajectories will depend on their ratio, "m/M", which contradicts the equivalence principle - although, truth to be said, I didn't quite understand whether you can choose "m" and "M" for each object/particle arbitrarily and how they add up for bound states etc.

This is a good example showing how different principles needed for physical consistency are linked to each other. If you sacrifice the Lorentz symmetry, it's likely that the equivalence principle will fail, too.

### Sir Isaac Newton: birthday

Sir Isaac Newton was born on January 4th, 1643. As Cynthia has pointed out, today, the main page of Google.com used the first animated Doodle ever. Yes, an apple falls from the tree.

Because I consider Newton as the brightest theoretical physicist ever, I have never had the courage to post a biography about this giant - although it was partly ready back in 2008 when we celebrated the 365th birthday.

His achievements, beliefs, revelations, passions, and mistakes are just way too multi-dimensional and I don't want to end up with a ludicrous lower-dimensional projection of a man that all of us know, at least to some extent.

### China: heaviest snow since 1951

Officials in Florida are preparing the people across Florida for below-freezing temperatures. Record cold temperature hits Iowa. I could forget some of the remaining 48 states of the union so let me just say that CNN reports that deep freeze across the U.S. will get colder.

Al Gore's car got extre-hehe-mely hot, millions of degrees.

The United Kingdom experiences a very cold winter that is likely to last at least for another month (and Piers Corbyn adds February, too - let's see whether his prediction will become a failed guess). In the U.K., December 2009 was the coldest one since 1981. And BBC had this title. However, they had to change the title because it was humiliating the greatness of the Global Warming God (GWG) and the true believers got rightly offended by the truth: the truth is unacceptable, they said, and BBC agreed.

### Warming trends in England from 1659

Because the Hadley Center has released the final temperatures in Central England for 2009, I decided to calculate a few things. Although I have also played with the monthly data, this text will be purely about the 1659-2009 annual data. It's 351 years in total.

A related link: The counterpart of this article for the world's second oldest weather station appears in the article Czech ClimateGate: Prague's Klementinum censored
The average of the 351 numbers is 9.217 °C. The Pythagorean average of the deviation of the annual data from this average is 0.659 °C. The global warming advocates like to emphasize the warming trend in the last 30 years. How does the warming trend in the last 30 years - and in all other 30-year periods since 1659 - look like in Central England?

Click to zoom in: the y-axis is the warming trend in °C per century, the x-axis is time from 1659-1688 to 1980-2009.

In the late 17th and early 18th century, there was clearly a much longer period when the 30-year trends were higher than the recent ones. There is nothing exceptional about the recent era. Because I don't want to waste time with the creation of confusing descriptions of the x-axis, let me list the ten 30-year intervals with the fastest warming trends:

### David Gross and the 60th birthday of Israel

If you have want to know what David Gross said in 2008 at Technion (posted in October 2009) about the future of physics, the Jewish achievements in science, and the current politics in Israel, see this one-hour talk:

As you may expect, I would probably subscribe to every word he said, with some exceptions of his criticism of the current Israeli government etc.

Gross reviews the achievements of various disciplines of physics in recent decades (one of the unusual physics disciplines studied at the KITP is "physics of climate change": is that really necessary, David?) and says that the greatest progress is that we gained the informed ignorance: we can ask certain fundamental questions intelligently.

### LHC alarmists: a judge would rule "stop LHC"

In the previous article, I discussed various beliefs in the end of the world (Y2K, AGW...) and Carl Brannen has brought our attention to the following new physics.soc-ph preprint:

Eric Johnson: The black hole case: the injunction against the end of the world (PDF)
The lawsuits by the LHC alarmists have so far been rejected on technical grounds such as wrong jurisdiction. Thank God.

The author of the paper, an assistant professor of law in Tennessee, analyzes what a judge would probably think and say if he had to evaluate the case on its merits. To save the time of most of you, after having written 90 pages of the preprint, he would probably stop the LHC. I just wanted you to know what you may expect from the lawyers if they get a chance to have their say. ;-/

There's a dead lawyer and a dead hare on the road. Do you know how can you distinguish them? You will find a braking track in front of the hare. :-)

Johnson reviews some positive and negative things that people in many diverse groups have said about particle physics. He discusses the dynamics that killed the SSC. And he summarizes some statements about the "dangers" from the LHC alarmists on one side and the active physicists on the other side. He seems capable to extract the relevant pieces of the texts - but he is manifestly incapable to determine which arguments are valid and which of them are not.

### NYT op-ed about Y2K, AGW, and other cataclysmic prophesies

The New York Times printed an excellent op-ed by Denis Dutton, a philosophy professor in New Zealand:

It's always the end of the world as we know it
He discusses the Y2K fiasco as a template for global warming and other movements obsessed with the end of the world and "cosmic justice" that will destroy the sinful civilization. These movements, as he argues, simply recycle the old religious instincts that have fascinated the mankind for thousands of years.

Click the picture for more Y2K fear propaganda.

His detailed memories about the Y2K problem would be kind of amazing if I didn't remember they were really told by influential sources all the time. While 1999 - with its booming economy and subdued terrorism - should have been viewed as the ultimate happy year, journalists, pop-scientists, and the rest of pundits loved the Y2K meme.

The end of the world was coming once again. The elevators, cars, airplanes, banks etc. would crash, we were told. About 300 billion U.S. dollars were wasted for this "problem".

### Czech president: New Year address

Dear fellow citizens,

as every year, please accept my greetings and wishes for a peaceful, happy, and successful new year.

The first of January is usually a day to evaluate the previous year and to look at the following year whose first day we are just experiencing. I will do the same thing. Let me begin with the first point: neither we nor the future historians will consider the previous year to be a smooth deal.

The 2010s have begun. While 40% of the native English speakers call it the "twenty tens", 60% use the term "two thousand and tens". A natural short version of the name is "the teens". The options sound better than the "noughties" or "twenty zeros" that have ended.

The same decadal situation, just 30 years earlier...

A self-described physicist has calculated the decade that is just getting started. She obtained a different result ;-) and she just twitted:

after the 70s, 80s and 90s, how will this decade be called? The zeros? The first decade?
The lesson is: never allow your brain to sleep for 10 years because it decomposes before you manage to wake up.

What can you expect in the 2010s?

### Velvet divorce: 17 years

In September 1992, I became a part of the last group of federal Czechoslovak freshmen at the Charles University. Since 1992, there has been a lot of important Slovaks in my life.

Of course, all of it was proved wrong. Two mostly civilized nations (or subnations) with political leaders who have no interest to create new problems because they want to become influential in the new countries pretty much guaranteed that what we were doing turned out to be the Velvet Divorce. And it has actually improved the actual relationships between the Czechs and Slovaks.

A separation is often more peaceful and constructive than a forced unity.
