- One more graphical illustration of the Petite Vostok CO2 and temperature data.

A simple search for the CO₂ warming signal in the data supposed to show CO₂ warming.

UPDATE: 18/8 DMI average Arctic temperature 80N-90N ended as coldest on record since 1958: 0,34 K

In this little update i show how 2010 data was achieved - simply by counting pixels.

GISS use a 1200 km radius for the temperatures measured from land temperature stations. The 1200 km radius is also applied to the coastal land/city/Airport temperature stations thus "covering" up to 1200 km over the oceans. GISS for example "covers" the Arctic ocean from land stations. 

In this writing I aim to explore the best (latest) temperature data published before the global warming movement grew strong in the mid 1980´ies and compare with later data. In 2007 the IPCC did a similar compare, however IPCC published this graphic just showing a number of quite old (pre 1960) temperatures series:

In general, problems of temperature data are discussed.

The Dutch scientist Appy Sluijs from the University of Utrecht has compiled a fantastic useful and competent overview of the writings about the PETM where all specific issues of the PETM is considered wisely.

This is no news - but still needs to be told. NOAA can in many contexts come up with the hottest temperatures available. Here we take a look at the European Sea Surface Temperatures as of 3 may 2010.

The death of global warming from below?

Many smaller or bigger errors by the IPCC have been pointed out. More often than random, these errors happens to support IPCC viewpoints. This is perhaps the biggest problem for the IPCC. Here is yet another IPCC-viewpoint-supporting IPCC error.

At the end a few additions by Frank Lansner

Australian temperature stations has many years where data has been omitted.

What happened? CRU lost old essential data "when moving to new buildings" - what might be the explanation for Australia?

Next to the historic data-war on the Medieval Warm Period, the data war on the 1940-78 perhaps stands as the most bitter and intense climate disagreement.

What happened to the great temperature decline 1940-78?

Estimating the effect of temperature on the equilibrium pressure of the CO2 over the seawater. – In other words: To what extend does temperature regulate the concentration of atmospheric CO2?

At Hidethedecline we have the honour to present Dr Antti Roine´s new article where he investigates the thermodynamics behind the CO2 response to temperature.
 

Of many "battles in the climate wars" right now everyone should know what Chris Horner is up to.

IPCC introduced a new viewpoint on the "Medieval Warm Period" in 2001. Was IPCC representing the "consensus" on MWP? What happened to scientific results on the MWP after IPCC changed viewpoint?

It seems that CRU´s hadcrut3 Stockholm temperatures are wrong, in fact the hadcrut Stockholm temperatures appears around 0,7 degree Celsius too warm in recent years.

Oerlemans “glacier-temperature-proxy” shows a strong rise in temperature 1970-90 where the 1990 level exceeds everything seen since year 1600.

How was Oerlemans “glacier-temperature-proxy” created? After reading Oerlemans paper im not sure...

Most skeptics are aware, but it cannot be repeated too often: Temperature data presented before the global warming movement really started in the mid 1980´ies compared with recent official temperatures shows that the temperature trends 1940-1978 has been changed fundamentally.

American thinker compares raw data with NCDC adjusted data, and Rural data with Urban data.

From http://climatequotes.com a brilliant piece of investigation was made possibly revealing UK government attempt to dig up specific negative outcome of global warming.

Bangladesh and the climate debate, a summary.

Very near the sea surface, a huge area in the southern Bangladesh is inhabited by millions of people "Living on the edge". The sea level rises predicted, must be considered with the deepest concern.

After the CRU data leak, errors in global warming science, mostly from IPCC had more attention in the medias These errors pointed out around Jan-Feb 2010 were problems with scientific documentation of claims, and problems with exaggerations. “Himalaya-gate”, “Amazon-gate” these errors where dubbed, but earlier errors could have been called “Coral gate” (se A-Z, Corals) or “Positive-feedback-gate” etc. etc.

Phil Jones: "No global warming since 1995" and other statements - in short - from the CRU-director.

Phil Jones quoted by BBC:

"the debate had not been settled over whether the Medieval Warm Period was warmer than the current period. "

And why is this historical?

Analysis of how IPCC´s can illustrate warming trend over the Scandinavian area.

New paper i Science by Jeffrey A. Dorale et al. has determined that the western Mediterranean relative sea level was ~1 meter above modern sea level ~81,000 years ago.

Global temperature for the past 30 years has been undershooting the IPCC’s currently-predicted warming rates (pink region). The warming trend (thick red line) has been rising at well below half of the IPCC’s central estimate. Data source: SPPI index, compiled from RSS, and UAH. SPPI no longer uses any terrestrial-temperature datasets, because they have become near-universally discredited as unreliable.

A member of the panel set up to investigate claims that climate change scientists covered up flawed data was forced to resign last night, just hours after the inquiry began.

Philip Campbell stood down after it was disclosed that he had given an interview in which he defended the conduct of researchers at the University of East Anglia’s Climatic Research Unit (CRU), insisting that they had done nothing wrong.

After Glaciergate India has established its own body to monitor the effects of global warming because it “cannot rely” on the United Nations’ Intergovernmental Panel on Climate Change, the group headed by its own Nobel Prize-winning scientist Dr R K Pachauri.

Dr. Pachauri and the Intergovernmental Panel on Climate Change are now under intense scrutiny, facing accusations of scientific sloppiness and potential financial conflicts of interest from climate skeptics, right-leaning politicians and even some mainstream scientists. writes Elisabeth Rosenthal in The New York Times

Now another senior British climate scientist–this time Professor John Mitchell, the Met Office’s Director of Climate Science, is about the face the full force of the blogosphere for contemptuous breaches of the UK’s Freedom of Information Act (FOIA).

Climate debate heats up in Australian politics: new Skeptic Party created

Less ice melt in antarctica than expected: The Antarctic melting index has averaged about 35 million km² days per year (October to September, to be sure of keeping the austral summer months together) between 1980 and 2008. In 2009 it was only 17.8 million km² days, which is not only a record low but also continues a trend towards lesser annual indices that began in 2005. The melt extent was the second lowest recorded, reaching only half the average of 1.3 million km².

A LEADING British government scientist has warned the United Nations’ climate panel to tackle its blunders or lose all credibility.

Yet another blunder in that IPCC 2007 report which Kevin Rudd uses to justify his great green tax to “stop” global warming:

A United Nations report on climate change that has been lambasted for its faulty research is under new attack for yet another instance of what critics say is sloppy science -- guiding global warming policy based on a study of forest fires.
