World Temperatures Database
Back by popular demand and upgraded to allow patrons more choices to plot and view the data, we reintroduce the World Temperatures section of our website. Here, users may plot temperatures for the entire globe or regions of the globe. A newly added feature allows patrons the ability to plot up to six independent datasets on the same graph.

“Can We Really Call Climate Science a Science?”
Dr. Paul Roderick Gregory, professor of Economics and a research fellow at the Hoover Institution at Stanford, has written a must read article in Forbes, titled “Can We Really Call Climate Science A Science?” (New Nostradamus of the North)
THE INEXORABLE CAUSAL RELATIONSHIP BETWEEN CO2 AND TEMPERATURE
Climate alarmists would have you believe that the quantity of carbon dioxide in the atmosphere is the sole determinant (if pressed, they will say the primary determinant) of changes in global temperatures. Actually, however, both the proportion of CO2 in the Earth’s atmosphere and the Earth’s temperatures have varied widely over the planet’s history, with no apparent correlation between the two. The point is illustrated by this graph, based on data from C.R. Scotese and R.A. Berner:

The idea that CO2 operates as a kind of thermostat, so that by impoverishing ourselves we can cool down the planet, is so silly that it is remarkable that so many have been duped into believing it. (PowerLine)
It just has nothing whatsoever to do with “catastrophic anthropogenic global warming” (or any other nomenclature invoked to hide the complete failure of warmie prognostications).

Uncertain climate models impair long-term climate strategies
New calibration satellite required to make accurate predictions, say scientists
A new paper published in Philosophical Transactions of the Royal Society A, explains weaknesses in our understanding of climate change and how we can fix them. These issues mean predictions vary wildly about how quickly temperatures will rise. This has serious implications for long term political and economic planning. The papers lead author is Dr Nigel Fox of The National Physical Laboratory, The UK’s National Measurement Institution. (EurekAlert)
Climate ‘scientists’ arbitrarily increase fictitious effects of CO2 by 25% in latest model
Attention alarmists: the latest version of the world’s most widely used climate model arbitrarily increases the fictitious forcing from CO2 ‘back-radiation’ and non-existent positive-feedbacks from clouds by 25%, from a fallacious 3.2C to 4.0C per doubling of CO2. (Hockey Schtick)
Alarmist claim Amazon will dry up bites the dust: New paper says core of Amazon rainforest will remain stable & rainfall increase
A paper published this week in the journal Earth Interactions counters alarmist claims that ‘climate change’ will cause the Amazon to dry up and shrink by 85%, finding instead, “Our results suggest that the core of the Amazon rainforest should remain largely stable as rainfall in the core of the basin is projected to increase.” (Hockey Schtick)
New Paper “Land Use/Land Cover Changes And Climate: Modeling Analysis And Observational Evidence” By Pielke Sr Et Al 2011
We have a new paper that has been accepted for publication, that summarizes the current understanding of the role of land use/land cover changes on the climate system, as well as proposes approaches to further advance our understanding. The paper is

New paper shows clouds have a large negative-feedback cooling effect
A paper published last week in the journal Meteorological Applications undermines a key assumption of the theory of man-made global warming, finding that the cooling effect of clouds far outweighs a supposed ‘greenhouse’ warming effect. Alarmists claim clouds have an overall ‘positive-feedback’ warming effect upon climate due to ‘back-radiation’ of the ‘greenhouse’ gas water vapor. This new paper based on satellite measurements finds instead that clouds have a large net cooling effect by blocking solar radiation and increasing radiative cooling outside the tropics. The cooling effect is found to be -21 Watts per meter squared, more than 17 times the supposed warming effect from a doubling of CO2 concentrations [1.2 W/m2]. Another key assumption of the AGW theory topples in the face of real-world data showing the net feedback from clouds is strongly negative. (Hockey Schtick)
As Paul Reiter has repeatedly pointed out, notably in From Shakespeare to Defoe: malaria in England in the Little Ice Age, malaria was endemic north of the Arctic Circle, it is not and never was constrained by temperature.
Drop In Malaria Incidence, Despite Climate Change
According to scientific journal PLoS ONE, new research discovered that incidents of malaria cases in the East African highlands have dropped dramatically. 10 years ago, the region experienced a surge in malaria incidents, which researchers associated with climate change. (Medical News Today)
Global climate deal should wait another 4 years: Point Carbon
LONDON – A binding global pact to limit global emissions should not be finalized until 2015, according to a U.N. submission by Australia and Norway.
The two countries reckon it will take four years to agree a legally-binding deal that includes emission targets for developed and developing countries.
Such a pact would expand the current Kyoto pact that only applies to rich nations. (Reuters)
US: Global Discord On Climate Action
Mapmakers’ claim on shape of Greenland suddenly melts away
Prominent polar scientists have said there is “no support” for potentially “damaging” claims, made by The Times Atlas of the World last week, that Greenland’s ice cover has shrunk by 15 per cent over the past 12 years as a result of global warming. (Independent)
Times Atlas is ‘wrong on Greenland climate change’
Glaciologists say the ice cover is melting – but at nowhere near the ‘misleading’ 15% rate represented by cartographers (John Vidal, Guardian)
