Carbon starvation in glacial trees recovered from the La Brea tar pits, southern California.
Abstract
The Rancho La Brea tar pit fossil collection includes Juniperus (C3) wood specimens that 14C date between 7.7 and 55 thousand years (kyr) B.P., providing a constrained record of plant response for southern California during the last glacial period.... Here we report on delta13C of Juniperus wood cellulose, and show that glacial and modern trees were operating at similar leaf-intercellular [CO2](ci)/atmospheric [CO2](ca) values. As a result, glacial trees were operating at ci values much closer to the CO2-compensation point for C3 photosynthesis than modern trees, indicating that glacial trees were undergoing carbon starvation.... By scaling ancient ci values to plant growth by using modern relationships, we found evidence that C3 primary productivity was greatly diminished in southern California during the last glacial period.
WHEAT in a Field
The CO2 concentration at 2 m above the crop was found to be fairly constant during the daylight hours on single days or from day-to-day throughout the growing season ranging from about 310 to 320 p.p.m. Nocturnal values were more variable and were between 10 and 200 p.p.m. higher than the daytime values.
CO2 depletion
Plant photosynthetic activity can reduce the Co2 within the plant canopy to between 200 and 250 ppm... I observed a 50 ppm drop in within a tomato plant canopy just a few minutes after direct sunlight at dawn entered a green house (Harper et al 1979) ... photosynthesis can be halted when CO2 concentration aproaches 200 ppm... (Morgan 2003) Carbon dioxide is heavier than air and does not easily mix into the greenhouse atmosphere by diffusion...
The ice-core man
...Because of the high importance of this realization, in 1994 Dr. Jaworowski, together with a team from the Norwegian Institute for Energy Technics, proposed a research project on the reliability of trace-gas determinations in the polar ice. The prospective sponsors of the research refused to fund it, claiming the research would be "immoral" if it served to undermine the foundations of climate research. [WTF!!! IMMORAL to do research???-CV]
The refusal did not come as a surprise. Several years earlier, in a peer-reviewed article published by the Norwegian Polar Institute, Dr. Jaworowski criticized the methods by which CO2 levels were ascertained from ice cores, and cast doubt on the global-warming hypothesis. The institute's director, while agreeing to publish his article, also warned Dr. Jaworowski that "this is not the way one gets research projects." Once published, the institute came under fire, especially since the report soon sold out and was reprinted. Said one prominent critic, "this paper puts the Norsk Polarinstitutt in disrepute." Although none of the critics faulted Dr. Jaworowski's science, the institute nevertheless fired him to maintain its access to funding.... [So much for impartial science research -CV]
...Zbigniew Jaworowski, past chairman of the United Nations Scientific Committee on the Effects of Atomic Radiation, a participant or chairman of some 20 Advisory Groups of the International Atomic Energy Agency and the United Nations Environmental Program, and current chair of the Scientific Committee of the Central Laboratory for Radiological Protection in Warsaw....
...the UN does not rely on direct real-time measurements for the period prior to 1958. "The IPCC relies on icecore data -- on air that has been trapped for hundreds or thousands of years deep below the surface," Dr. Jaworowski explains. "These ice cores are a foundation of the global warming hypothesis, but the foundation is groundless -- the IPCC has based its global-warming hypothesis on arbitrary assumptions and these assumptions, it is now clear, are false."...
This perfectly closed system, frozen in time, is a fantasy. "Liquid water is common in polar snow and ice, even at temperatures as low as -72C," Dr. Jaworowski explains, "and we also know that in cold water, CO2 is 70 times more soluble than nitrogen and 30 times more soluble than oxygen, guaranteeing that the proportions of the various gases that remain in the trapped, ancient air will change. Moreover, under the extreme pressure that deep ice is subjected to -- 320 bars, or more than 300 times normal atmospheric pressure -- high levels of CO2 get squeezed out of ancient air."
"According to the ice-core samples, CO2 levels vary little over time," Dr. Jaworowski states. "The ice core data from the Taylor Dome in Antarctica shows almost no change in the level of atmospheric CO2 over the last 7,000 to 8,000 years -- it varied between 260 parts per million and 264 parts per million.
"Yet other indicators of past CO2 levels, such as fossil leaf stomata, show that CO2 levels over the past 7,000 to 8,000 years varied by more than 50 parts per million, between 270 and 326 parts per million....

And so the reputation of an exceptionally brilliant scientist is trashed by nameless bureaucrats.
At www.climateaudit.org..., Steve McIntyre reports an analysis he undertook to test the "sensitivity" of the "Regional Curve Standardised" tree-ring chronology (Briffa, 2000; Briffa at al., 2008) to the selection of measurement data intended to provide evidence of long-term changes of tree growth, and, ultimately inferred temperature variation through two millennia in the Yamal region of northern Russia. It would be a mistake to conclude that McIntyre's sensitivity analysis provides evidence to refute our current interpretation of relatively high tree growth and summer warmth in the 20th century in this region. A reworked chronology, based on additional data, including those used in McIntyre's analysis, is similar to our previously published chronologies. Our earlier work thus provides a defensible and reasonable indication of tree growth changes during the 20th century and in the context of long-term changes reconstructed over the last two millennia in the vicinity of the larch tree line in southern Yamal. McIntyre's use of the data from a single, more spatially restricted site, to represent recent tree growth over the wider region, and his exclusion of the data from the other available sites, likely represents a biased reconstruction of tree growth. McIntyre's sensitivity analysis has little implication, either for the interpretation of the Yamal chronology or for other proxy studies that make use of it.
Subsequently, a slightly different version of the RCS Yamal chronology was produced using the same data set but processed using an improved implementation of the RCS technique (Briffa et al. 2008). However, the difference between the 2000 and 2008 versions of the chronology is small.
The data set used in the above-cited work was assembled and supplied by our colleagues Ra# Hantemirov and Stepan Shiyatov (Institute of Plant and Animal Ecology, Ekaterinburg, Russia) who also published a version of this chronology (Hantemirov and Shiyatov 2002) based on a different processing method (corridor standardisation).
The AD portion of the data set, common to these three analyses consisted of measurements from 235 sub-fossil larch samples collected at numerous sites (see map) adjacent to the Porzayakha, Yadayakhodyyakha, Tanlovayakha and Khadytayakha rivers (Hantemirov and Shiyatov, 2002) and samples from 17 living trees growing at 5 sites in the vicinity of the sub-fossil trees.
McIntyre's analysis involved removing the measurement data for 12 trees (from 3 of these sites POR, YAD and JAH), data that make up the most recent part of our chronology, and replacing them with measurements from 18 trees growing at a different single site (KHAD), slightly to the south of the locations of the removed trees and originating from a different source. This alternative "modern" set was not considered or used by Hantemirov and Shiyatov or in the previous analyses (Briffa, 2000; Briffa at al., 2008)
Per usual, not the conspiracy deniers make it out to be. Here's Briffa et al's 2013 paper. Check it out for yourself.
...Assessing the value of tree-ring data for climate reconstruction is predicated on an understanding of the methods of tree-ring chronology production and the extent to which these methods affect the estimation of uncertainty. At issue is the representation of the tree-ring evidence itself, but also the implementation of specific regression or scaling techniques used to transform the tree-ring data into estimates of climate variability. Fundamental to this review is an exploration of the degree to which the different tree-ring variables and sub-sets of these data provide consistent, and hence mutually corroborative, evidence of inferred temperature changes....
It is implicit in dendroclimatology that parallel tree-ring data series extracted from adjacent trees exhibit common variations in time that represent the local tree-growth response to changing environmental influences..... ["environmental influences" can also include rain a more limiting factor once growth temp is reached - CV]
The simple RCS approach relies on the assumption that a common, single RCS function is appropriate to detrend all measured series. This assumption may not be valid, even for trees within a restricted area. Part of the observed reduction of ring width with increasing tree age is due to the change in stem diameter, which is actually dependent on growth rate rather than ring age, e.g. the reduction of measured ring-width in each year due to diameter change will be larger in fast-growing trees than in slow-growing trees. There is usually some random variation in the growth rates of trees at a site even under constant climate conditions....
The collection of tree-core samples ...provided by the European Union funded... continues with support from the Russian Foundation for Basic Research. These efforts produced a continuous 4000-year long larch (Larix sibirica Ledeb.) chronology whose year-to-year variability was shown to be associated with changes in June and July temperatures (Hantemirov and Shiyatov, 2002). The sample data that spanned the Common Era comprised some 265 sub-fossil samples and 17 of the longest-lived living-tree samples drawn from 5 sites in the region...
A continuous multimillennial ring-width chronology in Yamal, northwestern Siberia
Abstract
Remains of subfossil Siberian larch trees in the Holocene deposits of the Yamal Peninsula (Western Siberia) have been collected in order to develop a continuous, multimillennium tree-ring-width chronology. This work has produced a calendar-age dated 4000-year (2000 bc to ad 1996) series. From these data, summer-temperature variability in this region has been estimated on annual to multidecadal timescales. Radiocarbon dating of selected older material shows that the oldest subfossil wood is 9400 years old and the dates of the sampled material are generally distributed evenly through time. It will, therefore, be possible to develop a tree-ring chronology for more than nine millennia. ....
Certainly gives meaning to "Hide the Decline" from the climategate e-mails where Mike Mann spliced thermometer data to tree ring data to hide this fact.
On January 12, 2010, the inquiry committee (Foley, Yekel, Scaroni) and Dr. Brune met with
Dr. Mann to interview him. Dr. Mann was asked to address the four allegations leveled against
him and to provide answers to the fifteen additional questions that the committee had compiled.
In an interview lasting nearly two hours, Dr. Mann addressed each of the questions and follow up
questions. A recording was made of the meeting, and this recording was transcribed. The
committee members asked occasional follow-up questions. Throughout the interview, Dr. Mann
answered each question carefully:
• He explained the content and meaning of the emails about which we inquired;
• He explained that he had never falsified any data, nor had he had ever manipulated data
to serve a given predetermined outcome;
• He explained that he never used inappropriate influence in reviewing papers by other
scientists who disagreed with the conclusions of his science;
• He explained that he never deleted emails at the behest of any other scientist, specifically
including Dr. Phil Jones, and that he never withheld data with the intention of
obstructing science; and
• He explained that he never engaged in activities or behaviors that were inconsistent with
accepted academic practices.
Finding 1. After careful consideration of all the evidence and relevant materials, the
inquiry committee finding is that there exists no credible evidence that Dr. Mann had or
has ever engaged in, or participated in, directly or indirectly, any actions with an intent
to suppress or to falsify data. While a perception has been created in the weeks after the
CRU emails were made public that Dr. Mann has engaged in the suppression or
falsification of data, there is no credible evidence that he ever did so, and certainly not
while at Penn State. In fact to the contrary, in instances that have been focused upon by
some as indicating falsification of data, for example in the use of a “trick” to manipulate
the data, this is explained as a discussion among Dr. Jones and others including Dr. Mann
about how best to put together a graph for a World Meteorological Organization (WMO)
report. They were not falsifying data; they were trying to construct an understandable
graph for those who were not experts in the field. The so-called “trick”1
was nothing
more than a statistical method used to bring two or more different kinds of data sets
together in a legitimate fashion by a technique that has been reviewed by a broad array of
peers in the field.

Ever notice how it's always some point in the future that we never seem to get to? Alarmist have been spewing this BS for years, but are constantly changing their stories and moving the dates further and further out.
Much recent attention has been paid to the email about the “trick” and the effort to “hide the decline”. Climate scientists have complained that this email has been taken “out of context”. In this case, I’m not sure that it’s in their interests that this email be placed in context because the context leads right back to a meeting of IPCC authors in Tanzania, raising serious questions about the role of IPCC itself in “hiding the decline” in the Briffa reconstruction.
"I know there is pressure to present a nice tidy story as regards 'apparent unprecedented warming in a thousand years or more in the proxy data' but in reality the situation is not quite so simple… [There are] some unexpected changes in response that do not match the recent warming. I do not think it wise that this issue be ignored in the chapter."
For the record, I do believe that the proxy data do show unusually warm conditions in recent decades. I am not sure that this unusual warming is so clear in the summer responsive data. I believe that the recent warmth was probably matched about 1000 years ago.
I do not believe that global mean annual temperatures have simply cooled progressively over thousands of years as Mike appears to and I contend that that there is strong evidence for major changes in climate over the Holocene (not Milankovich) that require explanation and that could represent part of the current or future background variability of our climate.

According to current understanding, the MCA was not a universally warm epoch (see, however, Graham et al. 2011 ), although much of the Arctic was warm during the Medieval times. In contrast, the LIA, which most studies date between 1500 and 1850 AD, was most probably a global phenomenon (Mann et al. 2009 ).
Can you tell us which of those external and internal forcings can account for the current warming trend?

Each saros series starts with a partial eclipse (Sun first enters the end of the node), and each successive saros the path of the Moon is shifted either northward (when near the descending node) or southward (when near the ascending node). At some point, eclipses are no longer possible and the series terminates (Sun leaves the beginning of the node). Arbitrary dates were established by compilers of eclipse statistics. These extreme dates are 2000 BCE and 3000 CE. Saros series, of course, went on before and will continue after these dates. Since the first eclipse of 2000 BCE was not the first in its saros, it is necessary to extend the saros series numbers backwards beyond 0 to negative numbers to accommodate eclipses occurring in the years following 2000 BCE. The saros -13 is the first saros to appear in these data. For solar eclipses the statistics for the complete saros series within the era between 2000 BCE and 3000 CE are given in this article's references. It takes between 1226 and 1550 years for the members of a saros series to traverse the Earth's surface from north to south (or vice-versa). These extremes allow from 69 to 87 eclipses in each series (most series have 71 or 72 eclipses). From 39 to 59 (mostly about 43) eclipses in a given series will be central (that is, total, annular, or hybrid annular-total)....
The 1,800-year oceanic tidal cycle: A possible cause of rapid climate change
Charles D. Keeling and Timothy P. Whorf
Abstract
Variations in solar irradiance are widely believed to explain climatic change on 20,000- to 100,000-year time-scales in accordance with the Milankovitch theory of the ice ages, but there is no conclusive evidence that variable irradiance can be the cause of abrupt fluctuations in climate on time-scales as short as 1,000 years. We propose that such abrupt millennial changes, seen in ice and sedimentary core records, were produced in part by well characterized, almost periodic variations in the strength of the global oceanic tide-raising forces caused by resonances in the periodic motions of the earth and moon...
The IRD events identified by Bond et al. (1, 2) show high spectral power density in a broad band centered at about 1,800 years (0.55 ± 0.15 cycles/kyr). The authors do not explain why this period is so much larger than the 1,476-year average pacing of cool events, but the time-distribution of pacing (ref. 1, Fig. 6c; G. Bond, private communication) suggests that a majority of the events were about 2,000 years apart, with occasional additional events occurring about half-way between, evidently too infrequent to cancel out a dominant spectral peak near 1,800 years. Bond et al. (2) in addition found a spectral peak near 5,000 years whose possible cause was also not explained. We now propose an oceanic tidal mechanism that may explain the basis for both of these spectral peaks, consistent with the actual times of IRD events....
Alexander Ruzmaikin and Joan Feynman of NASA's Jet Propulsion Laboratory, Pasadena, Calif., together with Dr. Yuk Yung of the California Institute of Technology, Pasadena, Calif., have analyzed Egyptian records of annual Nile water levels collected between 622 and 1470 A.D. at Rawdah Island in Cairo. These records were then compared to another well-documented human record from the same time period: observations of the number of auroras reported per decade in the Northern Hemisphere.
The researchers found some clear links between the sun's activity and climate variations. The Nile water levels and aurora records had two somewhat regularly occurring variations in common - one with a period of about 88 years and the second with a period of about 200 years.
The researchers said the findings have climate implications that extend far beyond the Nile River basin.
"Our results characterize not just a small region of the upper Nile, but a much more extended part of Africa," said Ruzmaikin. "The Nile River provides drainage for approximately 10 percent of the African continent....

Attempts have been made to explain 20th century global warming exclusively by the component of irradiance variation associated with the Gleissberg cycle. These attempts fail, because they require unacceptably great solar forcing and are incompatible with the paleoclimatic records.

...ENSO-adjusted warming in the three surface temperature datasets over the last 2–25 yr continually lies within the 90% range of all similar-length ENSO-adjusted temperature changes in these simulations (Fig. 2.8b). Near-zero and even negative trends are common for intervals of a decade or less in the simulations, due to the model’s internal climate variability. The simulations rule out (at the 95% level) zero trends for intervals of 15 yr or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate....
Our results show that temperature records of at least 17 years in length are required for identifying human effects on global-mean tropospheric temperature.
UN IPCC scientist Eduardo Zorita publicly declared that his Climategate colleagues Michael Mann and Phil Jones “should be barred from the IPCC process…They are not credible anymore.” Zorita also noted how insular the IPCC science had become. “By writing these lines I will just probably achieve that a few of my future studies will, again, not see the light of publication,” Zorita wrote. A UN lead author Richard Tol grew disillusioned with the IPCC and lamented that it had been “captured” and demanded that “the Chair of IPCC and the Chairs of the IPCC Working Groups should be removed.” Tol also publicly called for the “suspension” of IPCC Process in 2010 after being invited by the UN to participate as lead author again in the next IPCC Report. link [Folow the links to original and to other comments by scientists]
only two dozen or so members on the governing boards of these institutions produced the "consensus" statements. It appears that the governing boards of these organizations caved in to pressure from those promoting the politically correct view of UN and Gore-inspired science. The Canadian Academy of Sciences reportedly endorsed a "consensus" global warming statement that was never even approved by its governing board.
Rank-and-file scientists are now openly rebelling. James Spann, a certified meteorologist with the AMS, openly defied the organization when he said in January that he does "not know of a single TV meteorologist who buys into the man-made global warming hype." In February a panel of meteorologists expressed unanimous climate skepticism, and one panelist estimated that 95% of his profession rejects global warming fears.
In August 2007, a comprehensive survey of peer-reviewed scientific literature from 2004-2007 revealed "Less Than Half of all Published Scientists Endorse Global Warming Theory."
"Of 539 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers 'implicit' endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis. This is no 'consensus,'" according to an August 29, 2007 article in Daily Tech.
In addition, a September 26, 2007 report from the international group Institute of Physics' finds no "consensus" on global warming. Here is an excerpt: "As world leaders gathered in New York for a high-level UN meeting on climate change, a new report by some of the world's most renowned scientists urges policymakers to keep their eyes on the "science grapevine", arguing that their understanding of global warming is still far from complete." The Institute of Physics is also urging world leaders "to remain alert to the latest scientific thought on climate change." ...
How Many Scientists Fabricate and Falsify Research? A Systematic Review and Meta-Analysis of Survey Data
ABSTRACT
...A pooled weighted average of 1.97% (N = 7, 95%CI: 0.86–4.45) of scientists admitted to have fabricated, falsified or modified data or results at least once –a serious form of misconduct by any standard– and up to 33.7% admitted other questionable research practices. In surveys asking about the behaviour of colleagues, admission rates were 14.12% (N = 12, 95% CI: 9.91–19.72) for falsification, and up to 72% for other questionable research practices. Meta-regression showed that self reports surveys, surveys using the words “falsification” or “fabrication”, and mailed surveys yielded lower percentages of misconduct....
See below regarding Zorita. He is apparently, and quite actively, publishing.
As I already said, you have to bow to the CO2 God to get a paper published.
Sounds like you're an advocate of Roy Spencer (Mr."God did it").
From the point of view of the scientific method, the null hypothesis is ALL CHANGE IS NATURAL.
It's easy to look at it that way if you don't understand the basis (and problems) with calculating a global average temperature anomaly. It's easy to look at it that way, jump on short term differences and ignore the overall trend.
And that is despite all the rigging of the temperature records.
It seems to be talking about "ENSO-adjusted" values? Have you seen the ENSO-adjusted values? Do they show a 15 year pause?
So NOAA gives a 15 year 'PAUSE' as the falsification criteria.
Yes, he did say that. And he was talking about things like ENSO and how that "noise" needs to be accounted for when looking at trends. "Noise" like the extreme El Nino of 1998. He was talking about how cherry picking short term "trends" is meaningless. A good example would be the flat "trend" seen in the 1940s-1970s. A "trend" that fades to insignificance over the long term.
Dr. Ben Santer said in a 2011 paper:
Can you provide a source for those statistics, what is the time span? Dr. Zorita is welcome to his opinion but it seems that he was wrong about his work not being published. He said that in 2009? He's been pretty busy since then.
The number of participating scientists has fallen from 2000 to 800 many leaving in outrage because of the twisting of their research. (And because the IPCC ship is sinking)
But I don't suppose the relative scarcity of anti-AGW papers could have anything to do with a relative scarcity of anti-AGW scientists.
Reaction to Wegener's theory was almost uniformly hostile, and often exceptionally harsh and scathing
Abstract
There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias....

No one has said that solar variation does not affect climate but deniers are fond of saying "Look! Cycles!" as if the fact that cycles exists nullifies the evidence that the current warming trend is the result of human activity. Now, how about some evidence that any of these are in play and can account for the level of warming witnessed in the 20th century.

8. Conclusions
The scenarios we have built explore two main questions for the 21st century, neither of which we know the answer to:
- Can adequate governance -- institutions and agreements -- be put in place to manage global problems?
- Will society's values focus more on enhancing material wealth or be more broadly balanced, incorporating environmental health and social well-being.
The way we answer these questions leads to four families of scenarios:
- Golden Economic Age (A1): a century of expanded economic prosperity with the emergence of global governance
- Sustainable Development (B1): in which global agreements and institutions, underpinned by a value shift, encourages the integration of ecological and economic goals
- Divided World (A2): difficulty in resolving global issues leads to a world of autarkic regions
- Regional Stewardship (B2): in the face of weak global governance there is a focus on managing regional/local ecological and equity....

Look at WHO did the inquiries and what connections they have. FOLLOW THE MONEY!
Water vapor is known to be Earth’s most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change
Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to double the climate warming caused by increased levels of carbon dioxide in the atmosphere...
"Everyone agrees that if you add carbon dioxide to the atmosphere, then warming will result,” Dessler said. “So the real question is, how much warming?"
The answer can be found by estimating the magnitude of water vapor feedback. Increasing water vapor leads to warmer temperatures, which causes more water vapor to be absorbed into the air.
arming and water absorption increase in a spiraling cycle.
Water vapor feedback can also amplify the warming effect of other greenhouse gases, such that the warming brought about by increased carbon dioxide allows more water vapor to enter the atmosphere. "The difference in an atmosphere with a strong water vapor feedback and one with a weak feedback is enormous," Dessler said.
Climate models have estimated the strength of water vapor feedback, but until now the record of water vapor data was not sophisticated enough to provide a comprehensive view of at how water vapor responds to changes in Earth's surface temperature. That's because instruments on the ground and previous space-based could not measure water vapor at all altitudes in Earth's troposphere...
What no one bothers to mention is CO2 has INCREASED while the temperature has stayed the same for 17 years and Water vapor has DECREASED GRAPH 1 and GRAPH 2 - OOPS!There went that assumption.
No one has said that solar variation does not affect climate but deniers are fond of saying "Look! Cycles!" as if the fact that cycles exists nullifies the evidence that the current warming trend is the result of human activity. Now, how about some evidence that any of these are in play and can account for the level of warming witnessed in the 20th century.
Abstract
Recent measurements have shown that the total solar irradiance decreased at a rate of 0.019% per year between 1980 and 1985, and may still be decreasing. Presumably, this reflects a cyclical variation that may or may not be related to the well-known cycles of solar activity. Using data on globally averaged sea surface temperature (SST) over the past 120 yr, I show that the solar irradiance may have varied in phase with the 80–90 yr cycle represented by the envelope of the 11-yr solar-activity cycle. As the last peak of this cycle occurred in 1955–60, the next minimum should be reached about the end of the century, by which time the solar irradiance will be reduced from its peak value by ~1% if the present decay rate of 0.019% per year is typical.
From Dimming to Brightening: Decadal Changes in Solar Radiation at Earth's Surface
Abstract
Variations in solar radiation incident at Earth's surface profoundly affect the human and terrestrial environment. A decline in solar radiation at land surfaces has become apparent in many observational records up to 1990, a phenomenon known as global dimming. Newly available surface observations from 1990 to the present, primarily from the Northern Hemisphere, show that the dimming did not persist into the 1990s. Instead, a widespread brightening has been observed since the late 1980s. This reversal is reconcilable with changes in cloudiness and atmospheric transmission and may substantially affect surface climate, the hydrological cycle, glaciers, and ecosystems.
Sunspots, the QBO, and the stratospheric temperature in the north polar region
ABSTRACT
There is an association between the polar stratospheric temperature in the northern winter and the solar cycle in the winters when the 50-mb equatorial winds are westerly: The lower the sunspot number in such winters, the lower is the temperature. No major mid-winter warmings occurred in these winters when the sunspot number was below about 100.....
Solar Magnetic Sector Structure: Relation to Circulation of the Earth's Atmosphere
ABSTRACT
The solar magnetic sector structure appears to be related to the average area of high positive vorticity centers (low-pressure troughs) observed during winter in the Northern Hemisphere at the 300-millibar level. The average area of high vorticity decreases (low-pressure troughs become less intense) during a few days near the times at which sector boundaries are carried past the earth by the solar wind. The amplitude of the effect is about 10 percent.
Interplanetary Magnetic Field Polarity and the Size of Low-Pressure Troughs Near 180°W Longitude
ABSTRACT
When the interplanetary magnetic field is directed away from the sun, the area of wintertime low-pressure (300-millibar) troughs near 180°W longitude is significantly larger than when the field is toward the sun. This relation persists during most of the winters of 1951 to 1973.
Influence of Solar Magnetic Sector Structure on Terrestrial Atmospheric Vorticity
ABSTRACT
The solar magnetic sector structure has a sizable and reproducible influence on tropospheric and lower stratospheric vorticity. The average vorticity during winter in the Northern Hemisphere north of 2ON latitude reaches a minimum approximately one day after the passing of a sector boundary, and then increases during the following two or three days. The effect is found at all heights within the troposphere, but is not prominent in the stratosphere, except at the lower levels.
Solar Wind Control of the Earth's Electric Field
ABSTRACT The sun-weather problem is placed within an electrical framework subject to experimental investigation. An explanation is suggested for how solar variability modulates the earth's electric field. The solar wind velocity is inversely correlated with the electrical potential of the ionosphere, a measure of the overall intensity of the earth's fair-weather atmospheric electric field. In seeking a physical cause of this relationship, galactic cosmic radiation was studied and it was also found to be inversely correlated with solar wind velocity. Thus, the earth's electric field intensity which is maintained by worldwide thunderstorm currents—a meteorological phenomenon—varies in phase with cosmic radiation. Since cosmic radiation is the primary source of atmospheric ionization, these findings support a proposed mechanism in which solar control of ionizing radiation modulates atmospheric electrification and thus possibly cloud physical processes. If the latter occurred, atmospheric energetics would be affected. ... [/exnew]
Charts of Earth's magnetic field vs temperature by Vukcevic
Do you know what "specific humidity" represents? Now, think about what it means if the temperature increases (like it did) and the specific humidity stays the same (of even drops a little bit). In order for that to happen it means that the amount of water vapor in the air has to increase. There is a greater mass of water in the atmosphere.
