business as usual

The keyword being business. Print a bad review of an automobile, never get invited to the press junkets and early model previews and so on provided by that company again. Pan an upcoming movie, never get invited to a media preview by that studio again. Bad review of a book? Never get a preview copy again. Etc. And losing that early "exclusive news" is more deadly to a publication than losing advertisement money.

you should also print Apple's side. for instance, when they say Kieren can't get in because there won't be enough room. I notice your article pointedly does NOT mention Kieren's size so I can only assume there is something to hide; perhaps Kieren is very large, like Godzilla size.

Re: but...

There is/was a weird bug in a recent version of Excel that would prevent it opening perfectly fine spreadsheets at pseudorandom; the same spreadsheet format with varying daily data would work 9 days out of 10 but the tenth day it wouldn't open. Has something to do with the new file format, zipped xml, in some way I assume.

I miss the older version.

Re: Storing semi text data in a tool designed to process numbers automatically.

If the column is not preformatted as the desired format, pasting as text doesn't help. And once it's been converted to floating point, it's rounded off and you can't format it back to integer.

Vanished global warming may not return – UK Met Office

Re: Question ...

Well, until somebody comes up with an explanation as to why the earth is 18 degrees C warmer than the moon despite receiving the same solar irradiation, if it's not for the global warming caused by CO2 in the atmosphere, as calculated by Svante Arrhenius more than a century ago.

The "pause" depends entirely on the fact that 1998 was a really really warm year. It's warmed since 1999. It's warmed since 1997. And so on for whatever year you want to begin with. Any competent statistician can inform you that means the "no warming" conclusion is shaky beyond any reasonable benefit of the doubt.

Of course, we've slowly worked our way up until we've reached the record level of 1998 routinely now, so even that thin denial will need to be retired soon.

In other words, the Americas will likely be warmer for the next decade, and/or Europe will likely be the same or cooler.

Which means the geographical centers of the "no warming since 1998" and "energy still being soaked up by the system going to come out somewhere" groups will swap.

Scientific consensus that 2014 was record hottest year? No

Re: Cut the sh*t!

1) Urban stations are individually adjusted to remove the urban heat island effect, based on trends in other local weather stations which are not part of the network. (Denialists know this; this is part of the "The data is worthless because its adjusted" bleat of the denier. They assert that adjusted data is worthless, and likewise if the data is not adjusted then it is worthless, as here because of the UHIs)

"Extensive tests have shown that the urban heat island effects are no more than about 0.05°C up to 1990 in the global temperature records used in this chapter to depict climate change. Thus we have assumed an uncertainty of zero in global land-surface air temperature in 1900 due to urbanisation, linearly increasing to 0.06°C (two standard deviations 0.12°C) in 2000." http://www.grida.no/publications/other/ipcc_tar/?src=/climate/ipcc_tar/wg1/052.htm#2221

2) It's not a oneway process where the monitoring station has become hotter because of more pavement, fewer trees, etc.; in many cases the monitoring station's location has become a park, or has become shadowed by buildings, tree growth, etc. Thus the individual adjustments above.

"Using satellite night-lights-derived urban/rural metadata, urban and rural temperatures from 289 stations in 40 clusters were compared using data from 1989 to 1991. Contrary to generally accepted wisdom, no statistically significant impact of urbanization could be found in annual temperatures. It is postulated that this is due to micro- and local-scale impacts dominating over the mesoscale urban heat island. Industrial sections of towns may well be significantly warmer than rural sites, but urban meteorological observations are more likely to be made within park cool islands than industrial regions." http://www.researchgate.net/publication/252960119_Assessment_of_Urban_Versus_Rural_In_Situ_Surface_Temperatures_in_the_Contiguous_United_States_No_Difference_Found

3) Neither well established urban areas, nor areas which are currently becoming urbanized show a UHI trend that explains the scale of the AGW recorded:

"We show examples of the UHIs at London and Vienna, where city center sites are warmer than surrounding rural locations. Both of these UHIs however do not contribute to warming trends over the 20th century because the influences of the cities on surface temperatures have not changed over this time. In the main part of the paper, for China, we compare a new homogenized station data set with gridded temperature products and attempt to assess possible urban influences using sea surface temperature (SST) data sets for the area east of the Chinese mainland. We show that all the land-based data sets for China agree exceptionally well and that their residual warming compared to the SST series since 1951 is relatively small compared to the large-scale warming. Urban-related warming over China is shown to be about 0.1°C decade−1 over the period 1951–2004, with true climatic warming accounting for 0.81°C over this period." http://onlinelibrary.wiley.com/doi/10.1029/2008JD009916/abstract

Antarctic ice at all time 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.

"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

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?

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.

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: 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.
