What surface temperature is your model really predicting?

Guest post by Roy Clark : Relations between CO2, Ocean currents, Surface Atmosphere temperatures are considdered en detail. - A very well written work we can only reccomend to our readers.   Roy: "The surface temperature that we need for atmospheric radiative transfer calculations is the ground temperature. This means the temperature of the ground under our bare feet. The temperature used in the climate record is the meteorological surface air temperature (MSAT)."

Greenhouse effect vs. Gravity - guest post by Roy Clark

I recommend Roy Clarks new writing: "Gravity rules over photons in the greenhouse effect".

Roy is intensely digging into the physics and dynamics behind the greenhouse effect, for instance he makes a 3 dimensional overview of greenhose effect vs. altitude vs. wavelength. That is, Roy enables a view of the greenhouse effect of the individual greenhose gasses as a function of altitude.

9,25 - a factor that could close the global warming debate

 

The CO2-sensitivity describes the warming effect induced by a doubling of the CO2 concentration in the atmosphere, and is thus the epicentre of the global warming discussion. Estimates of the CO2 sensitivity are very different, and the value range used by IPCC appears unlikely to physically impossible. To show this, I will focus on the factor between the total CO2 warming and then the warming from a single doubling of CO2 concentration.

Colder Arctic temperatures in the melt season vs. GISS temperatures.

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.

The perplexing temperature data published 1974-84 and recent temperature data.

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.

IPCC "Gates"

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.

Global warming trend 1.4 degrees/century, not 4 degrees

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.

Less snowmelt in Antarctica

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.
