Dan intriguing article regarding the influence of the number of stations on the global temperature measurement has been written by Ross McKitrick and published on his website here: http://www.uoguelph.ca/~rmckitri/research/nvst.html. Looking at his graph, the eye is instantly drawn to the apparent correlation between the stations and temperature.

There is a huge step in the raw mean temperatures around 1990 with a synchronous change in the number of stations. The adjustments and gridding methods employed to create the accepted global temperature records, are reportedly satisfactory to deal with such data aberrations and on visual inspection there is no immediately obvious problem. However, that does not rule out the possibility that the gridded end product contains artefacts of the processing and/or character from the raw data that are not related to climate and that could potentially distort the overall picture. This brief communication describes a method, utilising the dataset from Ross McKitrick and Joe D’Aleo, to calculate a historic temperature record through modelling the relationship between raw mean temperatures and the number of stations.

Dr. James Hansen of NASA’s Goddard Institute for Space Studies (GISS) has announced that 2010 was the “hottest year on record” – by 0.01 degrees. His claim has been widely touted in the press as strong evidence that the climate is rapidly heating – due to human generated CO2 emissions. Dr. Hansen has also stated: "I would not be surprised if most or all groups found that 2010 was tied for the warmest year." But most groups do not support his claim.

ABSTRACT: Sensor measurement uncertainty has never been fully considered in prior appraisals of global average surface air temperature. The estimated average ±0.2 C station error has been incorrectly assessed as random, and the systematic error from uncontrolled variables has been invariably neglected. The systematic errors in measurements from three ideally sited and maintained temperature sensors are calculated herein. Combined with the ±0.2 C average station error, a representative lower-limit uncertainty of ±0.46 C was found for any global annual surface air temperature anomaly. This ±0.46 C reveals that the global surface air temperature anomaly trend from 1880 through 2000 is statistically indistinguishable from 0 C, and represents a lower limit of calibration uncertainty for climate models and for any prospective physically justifiable proxy reconstruction of paleo-temperature. The rate and magnitude of 20th century warming are thus unknowable, and suggestions of an unprecedented trend in 20th century global air temperature are unsustainable.

The observations we have detailed herein illustrate that climate variability from year-to-year and decade-to-decade plays a greater role in Georgia’s climate than any long-term trends. Such short-term variability will continue dominating Georgia’s climate into the future.

On the outskirts of one of China’s most polluted cities, an old farmer stares despairingly out across an immense lake of bubbling toxic waste covered in black dust. He remembers it as fields of wheat and corn.

Yan Man Jia Hong is a dedicated Communist. At 74, he still believes in his revolutionary heroes, but he despises the young local officials and entrepreneurs who have let this happen.

‘Chairman Mao was a hero and saved us,’ he says. ‘But these people only care about money. They have destroyed our lives.’

Vast fortunes are being amassed here in Inner Mongolia; the region has more than 90 per cent of the world’s legal reserves of rare earth metals, and specifically neodymium, the element needed to make the magnets in the most striking of green energy producers, wind turbines.

Live has uncovered the distinctly dirty truth about the process used to extract neodymium: it has an appalling environmental impact that raises serious questions over the credibility of so-called green technology.

On 28 January 2011, eighteen scientists sent a letter to members of the U.S. House of Representatives and the U.S. Senate urging them to "take a fresh look at climate change." Their intent, apparently, was to disparage the views of scientists who disagree with their contention that continued business-as-usual increases in carbon dioxide (CO2) emissions produced from the burning of coal, gas, and oil will lead to a host of cataclysmic climate-related problems.

We, the undersigned, totally disagree with them and would like to take this opportunity to briefly state our side of the story.

In this report, we provide a review of Illinois’ climate history and show that there is little observational evidence of unusual long-term climate changes taking place that could be linked to anthropogenic “global warming”—despite the frequent prognostications to the contrary, often accompanied by doom and gloom scenarios.

The climate impact of the RGGI carbon dioxide emissions reduction plan is infinitesimal and inconsequential.

New Hampshire’s role in mitigating future climate change under RGGI is even less.

Most of all, the deceptive shell game continues. The Guide offers evidence that supports a direct effect of carbon which amounts to one measly degree if carbon levels double. It offers no evidence that positive feedback will amplify the results up to a wildly high 3 or 4 degrees, and it does not inform readers that there is empirical evidence that the feedback is negative and will thus attenuate that one minor degree. Thus the half-truths are broadcast, but the lies by omission border on deception.

In this report, we review New Mexico’s long-term climate history and find little in the way of evidence that greenhouse gas build-up in the atmosphere has altered New Mexico’s climate. Instead of long-term changes, short-term variability dominates the state’s average temperature, precipitation, and drought frequency. Current temperatures are not all that different than the ones observed at the beginning of the last century—100 years ago.

SPPI has published a new Book, The Many Benefits of Atmospheric CO2 Enrichment.

The full book can be purchased here: http://www.valeslake.com/bookmart.htm

Global warming alarmists tell us the horrors of increasing atmospheric CO2 concentration. Skeptics tell us that it's not all that bad. Finally, there is a non-apologetic treatise that tells us of the benefits of atmospheric CO2 enrichment in an alphabetical format. This extensively referenced 360-page color book by Drs. Idso and Idso tells us of fifty-five benefits of atmospheric CO2 enrichment, and belongs in the library of all who study CO2 and climate.

That's 55 benefits. Fifty-five!

The benefits are not squeezed out of computer models, but are based on real data. CO2, after all, is plant food, absolutely necessary for all of the biosphere.

As presently constituted, earth’s atmosphere contains just slightly less than 400 ppm of the colorless and odorless gas we call carbon dioxide or CO2. That’s only four-hundredths of one percent. Consequently, even if the air's CO2 concentration was tripled, carbon dioxide would still comprise only a little over one tenth of one percent of the air we breathe, which is far less than what wafted through earth’s atmosphere eons ago, when the planet was a virtual garden place. Nevertheless, a small increase in this minuscule amount of CO2 is frequently predicted to produce a suite of dire environmental consequences, including dangerous global warming, catastrophic sea level rise, reduced agricultural output, and the destruction of many natural ecosystems, as well as dramatic increases in extreme weather phenomena, such as droughts, floods and hurricanes.

As strange as it may seem, these frightening future scenarios are derived from a single source of information: the ever-evolving computer-driven climate models that presume to reduce the important physical, chemical and biological processes that combine to determine the state of earth’s climate into a set of mathematical equations out of which their forecasts are produced. But do we really know what all of those complex and interacting processes are? And even if we did -- which we don't -- could we correctly reduce them into manageable computer code so as to produce reliable forecasts 50 or 100 years into the future?

Temperature changes recorded in the GISP2 ice core from the Greenland Ice Sheet show that the global warming experienced during the past century pales into insignificance when compared to the magnitude of profound climate reversals over the past 25,000 years.

Until a few days ago I knew that the US government spent an excessive amount of taxpayer money on climate change research. It was just a general notion; I had read occasional articles showing the funding of certain agencies like NASA but I didn't know many specifics. Then on New Years Day, I wrote a very quick article where I randomly picked a document from a Google search showing funding for climate change. The numbers astonished me. I decided to take a closer look.

Scientists agree that the Brisbane floods are a consequence of the unusually severe la Niña phase of the el Niño Southern Oscillation, a naturally-occurring four-year cycle of warming and cooling of the world’s oceans, starting in the equatorial eastern Pacific and carried around the globe by the thermohaline circulation of ocean currents.

Scientists also agree – for it is a matter of record – that floods of similar severity have struck the east coast of Australia before: twice in the 19th century and most recently in 1974. These earlier floods could not have been caused by manmade “global warming”, because there was not enough of it to make any difference at that time.

The pressure has been mounting. The public doubt about global warming has been increasing in recent years given Climategate, and how promises of warm snowless winters failed. After cold and snowy winters in 2007/08 and 2008/09, the winter of 2009/10 was the coldest ever in parts of the southeast, and in parts of Siberia and the coldest since 1977/78 or 1962/63 in many parts of the United States, Europe and Asia. This past December was the second coldest in the entire Central England Temperature record extending back to 1659. It was the coldest ever December in diverse locations like Ireland, Sweden, and Florida. Reluctantly, alarmists changed their tune and the promise of warm and snowless winters as recent as 4 years ago morphed into global warming means cold and snowy winters.

The winter of 2009-2010 was a memorable one in the Northeast and Mid-Atlantic states, with locations like Philadelphia enjoying multiple massive snow storms that led to record totals for the winter. As with all exceptional weather events of late, the usual suspects blamed the occurrence on global warming. In a NOAA press release reported in USA Today (http://www.usatoday.com/weather/climate/2010-07-15-heat-record_N.htm), Jay Lawrimore stated that…

Four cold winters in a row ought to have raised questions in legislators’ minds about the competence of the United Nations’ Intergovernmental Panel on Climate Change, the IPCC, which they have generously but unwisely funded and trusted. The IPCC’s dire predictions of dangerous warming are not happening in observed reality.

December was indeed a December to Remember (or for many, to forget!) with widespread cold and snows. The Central England Temperature record is one of the longest continuous temperature records in the world extending back to the Little Ice age in 1659. December 2010 was the Second Coldest December Temperature in the entire record (352 years) with an average of -0.7C just short of the record of -0.8C recorded in December 1890.
