In answer to the question of how unusual was 20th-century global warming, climate alarmists typically respond with the word unprecedented! But is that really so?

We know that 20th-century global warming represents the recovery of the world from the global chill of the Little Ice Age, which had been preceded by the Medieval Warm Period, which in turn had come about as a result of the warming that followed the Dark Ages Cold Period, which had been preceded by the Roman Warm Period; and so has Earth’s climate periodically shifted – from cold to warm, and from warm to cold – all the way back through the entire Holocene, as a result of some oscillating forcing factor that alternately warmed and cooled the planet on a millennial timescale. And we know that each of the between-period transitions was of approximately the same absolute magnitude. But what was the situation prior to the Holocene? (more…)

Churchville, VA—During a symposium held recently at the Holocaust Memorial Museum, Yale historian, Tim Snyder told the attendees: “Climate change acts as a “multiplier of other resource crises  leading to “the ecological panic that I’m afraid will lead to mass killings in the decades come.” In his attempt to predict the future, he is relying on historic resource crises that have led to mass killings, revolts, invasions, and famines. However, almost all of those resource crises came during the earth’s “little ice ages,” not during our planet’s warm cycles. (Neither Hitler nor Mao Tse Tung were driven by resource crises; Japan may have thought it was, but their invasion of China cost a terrible price) (more…)

Tree-rings prove climate was WARMER in Roman and Medieval times

  • Tree ring study gives first accurate climate reading back to 138BC
  • World has been slowly cooling for 2,000 years zithromax z-pak order online zithromax online
  • World was warmer in Roman and Medieval times than it is now
  • Study of semi-fossilised trees in Finland
Rings in fossilised pine trees have proven that the world was much warmer than previously thought – and the earth has been slowly COOLING for 2,000 years.

Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun.

The finding may force scientists to rethink current theories of the impact of global warming.

It is the first time that researchers have been able to accurately measure trends in global temperature over the last two millennia. (more…)

As much of America swelters through a heat wave, it’s not surprising that the usual suspects are telling everyone that it’s because of “global warming.”

We share the same views on the topic and have discussed them often. Our considered opinion is that this streak of blazing nonsense stems from the fact that—to put it in scientific terms—it’s summer and the sun is hot.”

On July 3rd Seth Borenstein, a reporter for the Associated Press, a newswire service that has been reporting global warming lies for decades, wrote that “If you want a glimpse of some of the worst of global warming, scientists suggest taking a look at U.S. weather in recent weeks.”


A 1600-Year Temperature History of Tropical South America

Wednesday, January 12th, 2011

Reconstructed tropical South American temperature anomalies normalized to the AD 1961-1990 average and smoothed with a 39-year Gaussian filter. Adapted from Kellerhals et al. (2010).

The authors write that “to place recent global warming into a longer-term perspective and to understand the mechanisms and causes of climate change, proxy-derived temperature estimates are needed for time periods prior to instrumental records and regions outside instrumental coverage.” And in this regard they note that “for tropical regions and the Southern Hemisphere … proxy information is very fragmentary.”

What was done
To help fill this data void, Kellerhals et al. developed what they describe as “a reconstruction of tropical South American temperature anomalies over the last ~1600 years … based on a highly resolved and carefully dated ammonium record from an ice core that was drilled in 1999 on Nevado Illimani [16°37’S, 67°46’W] in the eastern Bolivian Andes,” while noting that “studies from other remote ice core sites have found significant correlations between NH4+ concentration and temperature for Siberia and the Indian subcontinent for preindustrial time periods,” citing the work of Kang et al. (2002) and Eichler et al. (2009). As for calibrating and validating the NH4+-to-°C transfer function, they say they used “the Amazon Basin subset of the gridded HadCRUT3 temperature data set,” which is described by Brohan et al. (2006). (more…)

Should temperatures pulled out of a hat be the basis for energy and economic policies?

Average annual global temperatures have risen a degree or two since the Little Ice Age ended some 150 years ago. Thank goodness. The LIA was not a particularly pleasant time.

Prolonged winters, advancing glaciers, colder summers, more frequent storms and extended cloudiness reduced arable land, shortened growing seasons, rotted grain in wet fields, and brought famine, disease and death. Coming after the prosperous Medieval Warm Period – when farmers grew wine grapes in England and Vikings raised crops and cattle in Greenland – it must have been quite a shock. (more…)

Models Warm the Lower Troposphere Too Much: A Fingerprint Test with Updated Data (22 Sep 2010)

Climate models predict a hotspot of atmospheric warming in the tropical troposphere, but a new analysis suggests that real data do not show this hotspot, based on several types of surface and tropospheric data. Read More

Improved Analysis of Grace Data Shows Ice Accumulation in Greenland and Lower Global Ice Loss than Previous Studies (22 Sep 2010)

Estimates of current rates of ice loss for Greenland and Antarctica have been reduced by a factor of two, suggesting that almost none of the sea level rise over the past decade is due to glacial ice loss, which finding is rather odd if you believe the climate alarmist claim that the earth has experienced unprecedentedly warm air temperatures due to global warming over this interval.

The Tree Ring Circus

by John Dawson

The Hockey Stick Illusion is the shocking story of a graph called the Hockey Stick. It is also a textbook of tree ring analysis, a code-breaking adventure, an intriguing detective story, an exposé of a scientific and political travesty, and the tale of a herculean struggle between a self-funded sceptic and a publicly funded hydra, all presented in the measured style of an analytical treatise. The hero of the story is Steve McIntyre, honourably assisted by fellow sceptics, especially by Ross McKitrick. The villain is Michael Mann, dishonourably assisted by global warming alarmists, especially by his “Hockey Team”. The bare bones of the Hockey Stick story are as follows. (more…)

[Open letter to Tony Abbott]

Mr Tony Abbott MP
Leader of the Opposition
Parliament House,
Canberra, ACT

Dear Mr Abbott,

Although I am travelling in the US at the moment I have become aware of the controversy over your comments at an Adelaide school last week, including the public response by [a] scientist with an alarmist global warming bent.

You might be interested in the graph below. The data are temperatures reconstructed from Greenland ice cores and published in the peer reviewed literature. The data confirm pre-IPCC understanding of the climate history of the Earth: Earth warmed from the last glacial maximum about 15,000 years ago when great ice sheets covered North America and northern Europe and sea level about 130 m lower than today. By 9,000 years ago Earth had warmed to the Holocene maximum when temperatures were warmer than today; the Holocene maximum lasted until about 4,000 years ago and there has been irregular cooling since.

The IPCC alarmist claim that Earth’s temperature has been steady for the last 10,000 years but this view is at odds with historical and archaeological evidence (more…)

It is increasingly clear that the leak of the internal emails and documents of the Climate Research Unit at the University of East Anglia in November has done for the climate change debate what the Pentagon Papers did for the Vietnam war debate 40 years ago-changed the narrative decisively. Additional revelations of unethical behavior, errors, and serial exaggeration in climate science are rolling out on an almost daily basis, and there is good reason to expect more. (more…)
