Comment on What would Charles Keeling think? Science in spite of politics by Alexander Biggs
” from science being primarily an intellectual pastime of private persons to its present status as a major contributor to the quality of human life and the prosperity of nations.’
Advances in science have become so important to our lives that this change was inevitable. In climate research the absorption of IR energy by CO2 is important, so it is important to understand how CO2 absorbs energy. Some CO2 samples are richer in neutrons than others and since they ate heavy particles which have the required degrees of freedom to vibrate more readily, absorb mote IR, and heat the air. However as the CO2 rises in the colder troposphere, it loses its ability to absorb IR ( the equipartian principle mo longer applies). So heat can escape from earth without hindrance and is the probable cause of the present hiatus.

–“2 C (3.6 F) is 20% of an inverse ice age.”
Global average temperature does not cause glacial cycles – local insolation variation does.
It would be more accurate to say that the global average temperature varied only 6C in spite of huge accumulations of ice.–
Global average temperature is directly related to ocean temperatures.
One could also say global average temperature is related to tropical average temperatures. But currently [last 100 million year or so] tropical
temperature has been “on average” is all about tropical ocean temperature.
More the 70% of Earth surface is ocean. More than 80% of tropics is ocean.
Earth for last say 1 billion years, has had about 30% of area being land.
And currently most of the land and 90% of human population is lives in northern hemisphere.
In terms the relation to global temperature and climate the most important chunk of dry land is the Antarctic. Which a modest size continent which comprised of mostly glacial ice. Antarctic has highest average elevation of any continent- and this is only due to it’s glacial ice- else is would lowest elevation of any continent- though if removed pf all that ice, the reduction in weigh would cause the continental land mass to spring back up- requiring thousands and millions of years to do so.
The antarctic is a large frozen desert region- it doesn’t get much snow.
But it’s cold so the snow stays and builds up despite it being a desert,
It’s like a non-frost free freezer- though much colder than normal freezers. Despite how cold it is, there are still liquid lakes of water at the Antarctica [under thick layers of ice]. An interesting idea is that such water is not merely warmed by the thermal heat of Earth. Here’s fairly old paper [though I am not aware of it being “corrected”/refuted]:
** Report on Victoria University of Wellington Antarctic Expedition 1961-62 **
“Lake Vanda is shown to be a natural example of the trapping and storing of solar energy by a salt water density gradient. The bottom of this lake (218 ft) is maintained at 25°C despite a mean annual air temperature of about −20°C, the solar heating being limited to the short Antarctic summer.”
http://nzetc.victoria.ac.nz/tm/scholarly/tei-VUW1961-62Anta-t1-g1-t2.html
So that’s region of Antarctic which isn’t colder then a freezer- rather it’s warmer part of Antarctic and average air temperature is about the same as typical deep freezer. Or couple feet under that lake, ice it is exactly like a block of ice kept in deep freeze- not colder.
The antarctic is important because of what does to the ocean circulation- the wind and ocean circulated around the continent.
As for the northern hemisphere land mass a large chuck of it is a frozen wasteland- or number 1 and 2 of largest countries land area has average average below 0 C.
But the cold of Canada and Russia and the larger Antarctic Continent are insgnifcant in terms of average global temperature as they are tiny part of surface area of Earth, what determines average temperature is the much larger tropical zone which is largely ocean.

Comment on Charlie: Challenging free speech by Willard
World leaders had linked arms to march in Paris against terrorism after Islamic extremists killed 17 people. Merkel stood in the front row between French President Francois Hollande and Palestinian President Mahmoud Abbas.
But readers of the Hamevaser newspaper’s Monday edition didn’t know, as she had been digitally removed, leaving Abbas standing next to Hollande. Israeli media joked it was meant to bring Abbas closer to Israeli premier Benjamin Netanyahu, who was standing nearby.
Within the insular ultra-Orthodox community, pictures of women are rarely shown in newspapers and magazines due to modesty concerns.
In Jerusalem, ultra-Orthodox vandals frequently deface buses and billboards bearing advertising deemed immodest. Visitors to the religious neighborhood of Mea Shaarim are greeted with signs saying: “Please do not pass through our neighborhood in immodest clothes.”
“A woman’s exterior should not be seen and photographed or paraded in front of men,” said Yosef Haim, a neighborhood resident. “I think it’s a very positive thing.”
The picture in Hamevaser cut out other women, like Paris Mayor Anne Hidalgo, though the newspaper clumsily left her dark glove on the sleeve of a marcher. The European Union’s foreign policy chief, Federica Mogherini, was also cropped out.
Binyamin Lipkin, editor of Hamevaser, said the newspaper is a family publication that must be suitable for all audiences, including young children.
“The 8-year-old can’t see what I don’t want him to see,” he told Israel’s Channel 10 television station. “True, a picture of Angela Merkel should not ruin the child, but if I draw a line, I have to put it there from the bottom all the way to the top.”

Gee, that’s funny, Willard.
I always figured that all those terrorist acts in Northern Ireland were committed by Muslims – because, you know, Islam is unique in inspiring murders…but given those numbers, I’m thinking it might not have been the case after all. I heard a rumor that the violence was committed by Protestants and Catholics….but I always figured that couldn’t be the case.

<blockquote> It turns out that McIntyre did not know how to use centered PCA and made the mistake of using only the first principle component. Keeping the correct number of PC’s creates a Hockey Stick out of Mann’s Hockey Stick Data.</blockquote>All sorts of deliberate deceptions buried in that BS.
First of all, McIntyre knew perfectly well how to use centered PCA, but he was duplicating Mann's work which used uncentered PCA.
Second, he simply duplicated Mann's work which displayed the first two principle components. The <i>"correct number of PC’s"</i> to create a hockey stick was <b>4!</b>. IOW, whatever the "hockey stick" represented, it wasn't a temperature proxy. Or else, whatever the entire system of "Proxies" were proxies for, it wasn't temperature.
Finally, when he dug down into what was really going on, he discovered that Mann's method (decentering) dragged the effect of <a href="http://climateaudit.org/2010/11/11/strip-bark-growth-pulses/" rel="nofollow">Graybill strip bark chronologies and/or Yamal</a> into the first principle component. This is the "hockey stick", which Mann mistook for a temperature proxy. Whatever these stripbarks are proxies for, it isn't global temperature. Whichever principle component they're in.

Well now – this could be interesting:
Senate Majority Leader Mitch McConnell (R-Ky.) said Tuesday he will allow the Senate to vote on an amendment asking if they agree that climate change is impacting the planet.
[…]
But a measure proposed by Sen. Bernie Sanders (I-Vt.) had raised questions about whether he would stick to that commitment.
The Sanders measure asks whether lawmakers agree with the overwhelming consensus of scientists who say climate change is impacting the planet and is worsened by human-caused greenhouse gas emissions.
Given that Judith has testified before Congress at the invitation of Republicans, I wonder what she’ll do if they show that they disregard her views and insist that ACO2 emissions have no impact on the climate?
Will she ask to testify again to straighten them out? Will she tell them that she’ll no longer listen to them unless they change their views?

tonyb, “Since then the climate has cooled considerably but has started to edge up again.
tonyb”
Right, the edging up makes the turning down more likely. You have probably seen these, but what the heck.
The correlation of the tropical SST with global temperature anomaly is over 90%. So attempting to base past climate on higher latitudes is pretty futile, the correlation pretty much sucks.
Than would make Mann’s northern hemisphere tree work pretty much useless. Then if you complete the work Marcott started by focusing on the tropical temperatures and adding cap reconstructions, you would have a better indication of the real deal past climate driver, the tropical oceans.
Not to slight your CET extension work, but the tropics is where it’s at :)

Seeking understanding from those with more background, please.
“The margin of uncertainty we achieved was remarkably small (0.05C with 95% confidence).”This was achieved this, in part, by the inclusion of data from over 30,000 temperature stations, and by the use of optiized statistical methods. Even so, the highest year could not be distinguished. That is, of course, an indication that the Earth’s average temperature for the last decade has changed very little. Note that the ten warmest years all occur since 1998.” From pg. 3

On page 4, the land temp ranges appox. 1775 appear much higher (and broader) than now. Should one be concerned about the quality of sampling earlier vs. now? Thoughts?

my series of three linked articles might help to answer your question.

Article: History and reliability of global temperature records. Author: Tony Brown
This article (part 1 of a series of three) examines the period around 1850/80 when Global temperatures commence, and looks at the long history of reliable observations and records prior to the development of instrumental readings.

Article: A look at the reliability of the temperature record. Author: Tony Brown
This article – part two of a series of three- examines some of the inherent problems with the historic temperature record-such as methodology and instrumental error- that have been known for over a hundred years.
Article: A comparison of Global Temperatures and CET. Author: Tony Brown
This article – part three of three – examines the latest Global temperature figures from BEST and compares them to CET (Central England Temperatures). It illustrates that CET is a good – but not perfect – proxy for global temperatures and confirms the 350 year long warming trend –with numerous advances and retreats – that puts the Giss and Hadley temperature datasets into historical perspective as a staging post- and not the starting post- of increasing long term warmth.

Your explanation of what is happening is even kookier than Why.It’s.Not.CO2.’s!
It has nothing to do with the number of neutrons in the nucleus i.e. C12 vs C13. The CO2 molecule doesn’t lose its ability to absorb more IR as it rises. Less IR is absorbed because at those heights their are fewer CO2 molecules per cm3.
The probable cause of the slowdown in surface warming is mostly colder ocean surface temperatures in the Pacific as a result of the La Nina ENSO phase.

Danny Thomas, You should always be concerned with changes in sampling rates. Since I have a response to tonyb in moderation have a look at this.
That is a rough reconstruction of tropical temperatures using some of the Marcott selected data. Only thing is I added some out of sample higher frequency data he didn’t use. The higher frequency reconstructions indicate much more variability. Marcott’s confidence intervals were based on roughly 200 plus year smoothing so there would not be very much variability. You can’t say his reconstruction is wrong, he made choices and documented them, but his results are misleading.
The Berkeley situation is similar. they have a high confidence level due to infilling or kriging that decreases with the number of sampling points. Since the largest impact is in the polar regions and the worst sampling is in the polar regions their results pre-1955 are not all that fantastic mainly due to the south pole which tends to wander out of phase with the ROW. If you stick with regions that have reasonable sampling over the entire record, 45S-60N you would probably have a better idea of “global” temperature variability than using the whole “global” kriged anomaly.
Kriging is a great tool but it is not magic.
