Antarctic ice at ALL TIME RECORD HIGH: We have more to learn, says boffin

Re: Antactica is melting too

You're saying that there is no melting of the land ice in the Antarctic, from your deep theoretical understanding ("but to melt the ice; the air temperature has to be > 0C."), despite every scientific measure, despite photographic evidence of the antarctic glaciers shrinking. Wow.

Re: @hemidude - Review your math before trying physics again

"Yet, you claim CO2 is 0.4% of the atmosphere. Since you're off by 10x on this easily-checked fact, readers will be unlikely to take your other claims seriously."

Once you've made up your mind CO2 doesn't make a difference, it might as well be 400%, you're still going to say it makes no difference.

Re: Antactica is melting too

Everything has "approaching-infinite variables."

Yet the tidal charts seem fairly accurate despite the unknown effects of objects in the Kuyper belt, for one instance.

At some point, a model is accurate enough for the intended use. This is true for all models, for all uses. I can drive a car without having to consider relativistic effects, nor quantum uncertainty.

I can estimate the average temperature for this region next July, despite the approaching-infinite variables involved there.

Re: Antactica is melting too

You really don't understand radiative forcing.

"our currently stable negative forcing environment "

What does that mean?

" A positive forcing (more incoming energy) warms the system, while negative forcing (more outgoing energy) cools it. Causes of radiative forcing include changes in insolation and the concentrations of radiatively active gases, commonly known as greenhouse gases and aerosols."

Re: Antactica is melting too

"CO2 is 0.4% of the atmosphere it has no effect on global temps "

It's been known for a century that the earth is approximately 33 degrees C warmer than the solar energy received can account for. Compare to the temperature of the moon, for instance, adjusting for different albedo.

http://www-ramanathan.ucsd.edu/files/pr72.pdf

"The global average mean surface temperature of the earth is 288 K (Table

2.1). Above we deduced that the emission temperature of the Earth is 255K,

considerably lower."-2.3 The greenhouse effect http://www.geo.utexas.edu/courses/387h/Lectures/chap2.pdf

"The Earth has a moderate greenhouse effect which increases the surface

temperature by some 40 K over the blackbody temperature." http://www.astro.uvic.ca/~venn/A201/maths.7.planet_temperature.pdf

Have you ever tried your experiment?

Re: Antactica is melting too

Sure... it's too hard to believe that CO2 absorbs energy even though you can demonstrate it in the lab, it's much easier to believe the earth suddenly tipped over in its rotation for no particular reason, without anybody noticing, no coriolis effects, no gyroscopic effects.

Well, we've got the warming is because the earth tipped over, the sun's getting warmer, sunspots are keeping cosmic rays from forming clouds to cool us, volcanoes, and the earth isn't getting warmer after all. Yep, that "can't be CO2" theory just keeps getting better and better.

Re: Antactica is melting too

How does the Antarctic ice increase if the earth is a closed system?

Gee, do you think it's associated with the years of drought experienced in the US Southwest, and the Middle East; and the existence of a device called a "cold trap" which you use to dehumidify air, by passing it over a cold surface so that the water vapor freezes out?

Or does your understanding of global warming make you think that Antarctica is now significantly warmer than the freezing point of water?

Re: Antactica is melting too

fer crissakes, the Antarctic land ice has melted to the point where it's affecting the earth's gravity.

Re: Antactica is melting too

Doesn't even need to be melting land ice; just rain and/or snow will do the job. The atmosphere as a whole is getting moister due to the temperature rise; in particular the southern ocean is warming, resulting in more evaporation which will condense in the coldest air around, over Antarctica. The extra heat has made the ocean into more of a still, moving pure water to Antarctica. The pure water dilutes the salt, raises the freezing point, etc.

Furthermore, the lower salinity on top is less dense, reducing the upwelling of warmer water from below, which is saltier and heavier, thus the layer on top stays colder and less salty, both lead to more ice.

Another hypothesis is that increased winds and/or currents move the ice around generating open water, which then freezes.

Re: Antactica is melting too

No, what he's saying is:

the sea water is <0 C but not freezing because of the salt content.

The land ice is melting and diluting the sea water, thus raising the freezing point to where it's above the current sea temp, so it freezes.

I don't know if that theory is correct or not, but you should at least be able to follow the reasoning.

Re: Train yourself

With popular music especially, the sound quality depends on what the engineer was mixing on, and presumably what kind of equipment he was mixing it for. Early Beatles albums, for example, sound great on good systems, but with early stones albums, the better the system the worse they sound. Either they were designed for crappy 60s car radios and cheap record players, or the engineers blew it.

Re: Emotional response

My advice when testing audio components for purchase (does anybody do that anymore?) was not to use some track you liked; you'd enjoy it if it was some drunken chimp playing it on a kazoo. But if a system could make you pay attention and admire something that you were kind blah about, that was a good system.

Re: The Holy Church of Sound.... again...

Can't say that it's true in the digital world (although it probably is) butnin the analog recording world there's no doubt that the distortions from the electronic components were orders of magnitude less than those from the mechanical components, I.e. the vinyl/cartridge system and the speakers; and of those two, the greatest single source of alteration in the signal was the interaction between the speakers and the listening environment.

Re: DOUBLE-BLIND-TEST

You don't need a large scale test; if one person can reliably and repeatably tell the difference in a double blind test, then the difference is there; and there is no reason to think that a person with no real hearing deficits cannot learn to hear it with experience.

Re: One thing which hasn't been mentioned re MP3 encoding

If you can actually mp3s to decode, you have a way to detect problems which it's much easier than listening intently. Set up (or find a high schooler who can still do hardware) a good opamp with the original signal going in the plus and the signal run through the coder and decoderb into the minus, then adjust the levels to get the best cancellation, I.e. the output volume of the signal should be nearly zero. (Feed the opamp output into your listening system, I forgot to say) obviously, anything still audible will be distortion, caused by the digital process.

The last time I tried this with an outboard PCM encoder and decoder system I was really badly surprised at how much grunge was audible, and more importantly how really irritating it was. Admittedly, however, that was 30 years ago. I'm sure that since then, manufacturers have learned to make things worse.

Lest you think I'm an old crank, let me introduce to to the Aphex Exciter; a recording too used to deliberately add irritating distortion to the music, to make it really pop out at you. (Yes that's where Aphex twin got the name) When solid state took over from tubes, everybody raved about the brilliant highs, until they were proved to be distortion. Exact same thing when CDs took over from vinyl. Just add some popping and fizzing whenever your recording hits a high frequency, and it sounds awesome. But you get fatigued quite quickly.

Re: One thing which hasn't been mentioned re MP3 encoding

That's a good point; although the theoretical digital processing may be undetectable to human ears, one very seldom finds cheap chips which perform to theoretical perfection. Thus the use of 24 bit DACs in good CD players, to decode 16 bit encodings; because the bottom few bits on cheap DACs are worthless, so if you want real 16 bit accuracy in real life, you need to spec a 24 bit chip.

Re: BRAWNDO!! IT'S GOT ELECTROLYTES!

Despite the fundamentalists' (again false) belief that they represent traditional religion, it is only the religion of the Dark Ages in Europe which they represent.

More often, traditionally, science and religion did not clash; to the scientists of the Enlightenment, Newton for example, scientific study and discoveries were another form of worship; unfortunately, I can't remember which one it was who said that nature provided another Testament, the language of which was mathematics.

And even before that, while Europe was in the Dark Ages, the Islamic world unequivocally tied science to the glory of God, and the foremost Jewish thinker of the post-Talmudic era, Maimonides, around 1100 used as a starting point the assumption that to use scripture to try to refute either the teachings of science, or common sense, was a grievous error.

The fundamentalists of today, no matter what particular religion they espouse, all share intellectual laziness or incompetence, the very opposite of what the great figures in religion historically represented.

Re: Breaking News!!

" CO2 levels rise - the Earth warms."

* No, it is Earth warms -> CO2 rises."

Sure, if you ignore the known IR absorption of CO2, and the big dent in the earth's radiated EM energy, right where CO2 absorbs

http://clivebest.com/blog/wp-content/uploads/2013/02/nimbus-satellite-emissions-infra-red-earth-petty-6-6.jpg

https://24.media.tumblr.com/f89a8bab132b46121d5e77089db217ab/tumblr_n11kv8guXp1t4esr2o1_500.jpg,

and conservation of energy, and the earth's temperature being 33 degrees C warmer than it should be purely from the sun's radiation at this distance (take the moon for example), then sure, the earth wouldn't warm proportional to the log of the CO2 concentration. On the other hand, if you accept all these, and as the earth warms, CO2 rises (which seems to be true), then we are kind of entering a bad period. Much as the Australian colonists experienced, without having to debate whether the number of baby rabbits rose after the number of adults, or was it that the number of adult rabbits rose after the number of babies?

" Computer models used by warmers produce high correlation between the temperature and CO2. The CO2 concentration has been rising very fast in the last 15 years, while the temperature is almost flat."

Just like it was almost flat from Jan '70 to Nov '77, Nov '77 to Nov '86, Sep '87 to Nov '96, Mar '97 to Oct '02, and Oct '02 to Dec '11 yet, that didn't seem to signal the end of the 42-year warming trend nearly linear from Jan '70 to Dec '11 (which you need, to explain your "Earth warms -> CO2 rises" and " CO2 concentration has been rising very fast in the last 15 years"). Denialists are like an ant climbing a staircase, who repeats "Whew, glad the climbing part is over" every time he gets to the flat part of a tread.

"The models do not model clouds and therefore the feedback mechanisms"

Well, yes they do, they always have. However, the IPCC has always stated that cloud feedbacks were the most uncertain of the modeled effects. Spencer et al used to rely on the hope that these effects would be negative. But that argument was valid 10 or even 5 years ago, not today.

So, you and Roy Spencer, as shown by his graph you linked to, admit that it IS warming, about 2-3 degrees C per decade, but not 6 degrees per decade? Well, that's a start. However, it's clear from the graph that he has displaced the "actual" temperatures to make them appear lower, by picking an alignment point to just this effect, i.e. a peak in the actual temps to a valley in the model, rather than aligning them to maximize closeness, as would be the logical and/or honest basis.

Re: A quick correction

Even on a 5-year-average plot, which is abysmally noisy, you can see the JMA current estimate is above that from 1990 (I should probably point out that that is your "22 years", given the math skills discernible from the context), and that the slope is positive, both by linear fit and by eye. http://ds.data.jma.go.jp/tcc/tcc/products/gwp/temp/ann_wld.html

If you bother to go even further, and read the site in addition to bothering to look at the graphed data, you see that the JMA DOES NOT COVER THE POLES, which are warming faster than the rest of the Earth. http://ds.data.jma.go.jp/tcc/tcc/products/gwp/temp/explanation.html

The text on that page further describes their procedure for generating an overall global estimate from a time sequence of gridded point data, or as your quaint phrase puts it, "fiddling the figures"; so you can see that "Not fiddling the figures" doesn't enter into it. It's not in Japanese, it's in English, if you can read that language.

The JMA kindly sprinkles other clues around their website, should you wish to avail yourself of them. For instance,

"The seasonal mean temperature for the summer from June to August 2010 over Japan was the highest among the historical records held by the Japan Meteorological Agency (JMA) stretching back 113 years to 1898. ... The annual anomaly of the global average surface temperature in 2010 (i.e., the average of

the near-surface air temperature over land and the SST) was 0.34°C above normal (i.e., the

1971 – 2000 average), second only to that of 1998 since 1891."

Romans, Han Dynasty, kick-started climate change

gzuckier

"Sapart feels the results mean climate scientists need to rethink what is a "normal" state for Earth's climate."

Uh, that would be hot, humid, and full of CO2, just as it was for the great majority of Earth's history, for billions of years before the current short time since photosynthesis sidetracked a lot of that CO2 out of the atmosphere and it got buried underground, resulting in an anomalous cool, dry, and less stormy epoch.

Of course, this deviation from the "normal" state is only metastable, and the potential energy stored in that fossil carbon means that it will eventually be returned to the atmospheric CO2 pool again and the climate will return to its normal hot, humid, and stormy state, like it was before there was any life on land. Wonder how/when that will happen?

Well, gee, nothing spells doom to a theory that hypothesizes that global average temperature has entered a new phase over the past century or less and has abruptly begun rising half a degree per decade or so, than a graph of "summer temperatures" which claims "the climate was often hotter than today", with no units on the temperature scale, on which the aforementioned last 100 years covers less than 7 mm and shows a distinct upwards streak, and on which the peak temperature a few years ago is seen to be higher than anything on the graph all the way back to a couple hundred BC, medieval warm period included.

I'll look up the original study later, but if this graph is the best argument you can provide, the you apparently don't understand the issues under discussion, no matter what the study says.
