----------------------------------------The longest continuous record of atmospheric carbon dioxide levels (1958-present) comes from Mauna Loa Observatory in Hawaii. In many ways the mountain is the ideal location for studying the atmosphere. Isolated in the Pacific, it is far from major sources of pollution. Its high-altitude, lava-coated flanks are free of plants and trees, whose cycles of photosynthesis and respiration affect carbon dioxide concentrations. On the other hand, there would seem to be a major problem with measuring carbon dioxide at Mauna Loa: the mountain is an active volcano. This natural-color satellite image of the summit of Mauna Loa overlaid with 100-meter (330-foot) contour lines helps illustrate why volcanic emissions from the summit rarely reach the observatory. The observatory is located on the northern slope of the mountain, 6 kilometers (4 miles) away from and 800 meters (2,600 feet) lower than the summit. Most of the time, the prevailing northeasterly trade winds prevent volcanically contaminated air from reaching the observatory. Only on a small percentage of nights do the winds become light and southerly, pushing volcanic emissions downhill to the observatory. So, how do scientists know when this happens? Because the carbon dioxide analyzer is measuring emissions continuously, the scientists have an extraordinarily long record of baseline measurements. For days on end, carbon dioxide readings barely change at all (less than 3/10 of a part per million from hour to hour, according to Dr. Steve Ryan from the Mauna Loa Observatory). On the small number of nights when the winds at Mauna Loa come from the south, carbon dioxide concentrations at the observatory become variable, rising by several parts per million for minutes to hours. According to Ryan, These periods of elevated and variable CO2 levels are so different from the typical measurements that is easy to remove them from the final data set using a simple mathematical filter. A more detailed discussion, including graphs of carbon dioxide data collected at Mauna Loa and other observatories around the world, is available in our new Climate Q&A column.

Funny bit is the isotope 12 or 13 is why we know where the CO2 is coming from...fossil fuel, but regurgitating these basics is just too insulting. Ain't true-ists recycling their same questions after having gone through full circle baiting and making zero catch.
----------------------------------------Just came off the mountain from a quick up and down trip and took some pictures of the opposite ski slopes, visibility presently well exceeding 150km. The slopes look like a far into primavera state... no ski-able snow left. It's melting faster than ever. Let's hope it Ain't True, though it is.

Here are eight others -- same results. I only see one graph, no data and no paper ref. What happened to the other 7 graphs and referencing? You do realise that by itself that graph makes it look like Mauna Loa, "the biggest volcano in the world", produces all the CO2 in the world ![]() |

carbon isotope trends...
----------------------------------------http://blogs.edf.org/climate411/2007/02/22/linder_logic/ CO2 is a molecule that contains carbon atoms, and most of the carbon atoms on the earth come in two forms. About 99% are what we call carbon-12, and about 1% are carbon-13. In measuring atmospheric CO2, scientists found an interesting trend: CO2 was increasing over time, but the ratio of carbon-13 to carbon-12 was decreasing. Measurements of tree rings showed that this trend began in the late 1800’s. The explanation? The percentage of carbon-13 in fossil fuels is less than the percentage of carbon-13 in the atmosphere. So when fossil fuels are burned, the ratio of carbon-13 to carbon-12 in the atmosphere decreases. This trend is proof-positive (like a fingerprint or DNA match) that the additional carbon in the atmosphere since the late 1800's came from the burning of fossil fuels. Hmm… Maybe we need a second award for blatant misunderstandings of science.

Oh there's no doubt the amount of CO2 is increasing in the atmosphere from 0.028% to 0.0388%
----------------------------------------It's the extrapolated catastrophe on account of this that is the scientific nonsense How much of the increase is due to the warming (by the Sun) we saw over the last century as CO2 out-gasses from the ocean. When we have a warm year (like 1998) the increase is greater (check the record) skgiven that North Pole is doing exactly as expected under the reduced activity Sun ;-) Check out the delayed melt here http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm We don't have runaway climate change we never had and we never will - certainly not on account of CO2 - (otherwise we would be living with it today....no?) and the CO2 concentration in the past was way higher than it is today (until all those fossilised plants took it out of the atmosphere) Night from Kandahar 27C and as dusty as a cement factory Dave ![]() |

The conspiracy just continues quite nicely. What else to expect if 75% of the world population is in it!
----------------------------------------Phil Jones Exonerated by British House of Commons Tags: Desmogblog, climate change, climate gate michael mann, Climategate, Climatic Research Unit (CRU), cru stolen emails, General, global warming, hide the decline, hockey stick graph, House of Commons, peer review, Phil Jones, Science and Technology Committee, University Of East Anglia The British House of Commons today issued a report exonerating Professor Phil Jones, the director of the Climatic Research Unit at the University of East Anglia. Dr. Jones was embroiled in controversy following the theft of internal emails and documents from the University’s servers in November of last year. The report states that “the focus on CRU and Professor Phil Jones, Director of CRU, in particular, has largely been misplaced,” and that Dr. Jones’s actions were “in line with common practice in the climate science community,” and the CRU’s “analyses have been repeated and the conclusions have been verified.” The review by the House of Commons’ Science and Technology Committee began in January in the wake of the ‘Climategate’ media frenzy. While the committee’s report recommends that climate scientists should seek to improve transparency in their work, release raw data when possible, and provide more detail on their methodologies, the committee firmly concludes that there was no dishonesty on the part of Dr. Jones and the CRU. The committee compared the results of other independent analyses of climate data to that of the CRU, and found that they are consistent and independently verifiable. From a statement released by the committee to the press today: “The focus on Professor Jones and CRU has been largely misplaced. On the accusations relating to Professor Jones’s refusal to share raw data and computer codes, the Committee considers that his actions were in line with common practice in the climate science community but that those practices need to change. On the much cited phrases in the leaked e-mails—“trick” and “hiding the decline”—the Committee considers that they were colloquial terms used in private e-mails and the balance of evidence is that they were not part of a systematic attempt to mislead. Insofar as the Committee was able to consider accusations of dishonesty against CRU, the Committee considers that there is no case to answer.” Even if the data that CRU used were not publicly available—which they mostly are—or the methods not published—which they have been—its published results would still be credible: the results from CRU agree with those drawn from other international data sets; in other words, the analyses have been repeated and the conclusions have been verified. The committee’s report [PDF] provides detailed responses on each of the issues raised in its investigation. On the matter of Dr. Jones’ use of the phrase “trick” in an email referring to Michael Mann’s Hockey Stick graph, the Committee concludes: "Critics of CRU have suggested that Professor Jones’s use of the word “trick” is evidence that he was part of a conspiracy to hide evidence that did not fit his view that recent global warming is predominately caused by human activity. The balance of evidence patently fails to support this view. It appears to be a colloquialism for a “neat” method of handling data." On the matter of Dr. Jones’ email including the phrase “hide the decline”, the Committee concludes: "Critics of CRU have suggested that Professor Jones’s use of the words “hide the decline” is evidence that he was part of a conspiracy to hide evidence that did not fit his view that recent global warming is predominantly caused by human activity. That he has published papers—including a paper in Nature—dealing with this aspect of the science clearly refutes this allegation. In our view, it was shorthand for the practice of discarding data known to be erroneous." On the matter of whether Dr. Jones suppressed or perverted the peer review process, the Committee concluded: "The evidence that we have seen does not suggest that Professor Jones was trying to subvert the peer review process. Academics should not be criticised for making informal comments on academic papers." The report goes into further detail on Freedom of Information requests and other issues, culminating in a set of recommendations for improving data access and transparency at CRU and increased transparency in the scientific community at large to ensure that the science remains “irreproachable.” Download the full report: “The disclosure of climate data from the Clima...niversity of East Anglia. ”

Saw this line yesterday, where I'm sure the sin was originally Cardinal!
----------------------------------------"Ignorance is curable. Militant ignorance–the refusal to learn–is not. It’s intellectual sin." The wind up in the Arctic has flopped, this Compacting and Grinding has turned into "spread it thin". Just like the snow, reading messages from North America's getting through to the MSM to alert on the ever warming... not snow, but rain falling. Daily Departure - March 31, 2010 (Day 90) ![]() All that snow, some falling in Southern England is predicted for this week, because the climate IS changing. Solar minimum and a persistent El Nino enough to outdo by an order of magnitude anything the solar flux does. Would those preceding La Nina's in 2007-2008 have caused that much lauded global cooling and NOT the sun? WHY is that snow in the red marked zones missing so early in spring? Wake up, it's happening!
