Callendar, Jaworowski and Beck, who is believable?

According to Jaworowski there was cherry picking by Callendar as above and he gives reference.

Solar activity affecting the earth, the link

What follows is incomplete, I’ve decided to throw this out early, let the team help fill in more detail.

Tim Cullen: Illumination from the Geochemical Society

This is the first of two guest posts from Tim Cullen on the fascinating subject of photon production in planetary atmospheres:

The concept of a “fluorescing atmosphere” is generally dismissed as cranky [or just plain crazy] by most pundits and commentators.

Therefore, I am extremely grateful to Professor Mark A. Smith and Hiroshi Imanaka for publishing a truly remarkable paper on the Geochemical Society website that clearly illustrates that photons are produced in the atmosphere.

The blue emissions are indicative of atomic hydrogen [but there are other atmospheric atomic gases that emit blue photon – such as helium] and are produced in many ways [including]:
a) Electrons colliding with atomic gas particles.
b) Solar photon colliding with atomic gas particles.
c) Atomic gas particles recombining to form molecules.

Though less is directly known regarding the haze layers, lying predominantly below the direct reach of Cassini, much is now known regarding the atmosphere above the haze.

Using the Ion-Neutral Mass Spectrometer (INMS) on Cassini, we now know that even in the ionosphere, there is a rich and complex organic chemistry unparalleled in any known atmosphere (Waite, 2005; Waite, 2009).

Greenhouse Panic Over: New model demonstrates dependence of Planetary surface temperature on atmospheric pressure

New talkshop visitor ‘David’ has dropped a fruitful link on Wayne Jackson’s recent thread which, after a bit of sleuthing via AstroBio.net, leads to a new paper from the Trieste Astrobiology Group led by Giovanni Vladilo. This will be of great interest to our friends Nikolov and Zeller, because it vindicates their contention that atmospheric pressure is the principle determinant of planetary surface temperatures. However, there is a twist. As well as affecting the near surface heat capacity, evaporation rates and meridional energy transport, atmospheric pressure also affects the atmospheric optical depth of atmospheres, and this explains the role of ‘greenhouse gases’ and their radiative properties in contributing to the overall distribution and magnitude of energy at planetary surfaces. Although not dscussed in the paper, I think it will also be the case that regardless of extra emissions of a greenhouse gas such as carbon dioxide, since the pressure is the primary variable, the optical depth will remain constant, as NASA Physicist Ferenc Miskolzci found. If so, the Man Made Greenhouse Panic is over.

The pressure-dependent habitable zone is shown in the left figure below. The circles indicate solutions of the climate simulations with mean global annual habitability h>0. The area of the circles is proportional to the habitability h; the colors are coded according to the mean annual global surface temperature, Tm. The size and color scales are shown in the legend. The solid lines are contours of equal mean temperature Tm=0 C (magenta), 60 C (red) and 120 C (black). (Click for larger image)

The key passage from the paper is this one:

4.2.1. Surface Pressure and Planet Temperature Variations of surface pressure affect the temperature in two ways. First, for a given atmospheric composition, the infrared optical depth of the atmosphere will increase with pressure. As a result, a rise of [pressure] will always lead to a rise of the [radiative] greenhouse effect and temperature. Second, the horizontal heat transport increases with pressure. In our model, this is reflected by the linear increase with [pressure] of the diffusion coefficient D (Equation (A5), Appendix A.2). At variance with the first effect, it is not straightforward to predict how the temperature will react to a variation of the horizontal transport. In the case of Earth, our EBM calculations predict a rise of the mean temperature with increasing D. This is due to the fact that the increased diffusion from the equator to the poles tends to reduce the polar ice covers and, as a consequence, to reduce the albedo and raise the temperature.

A high resolution look at a sunny day

What follows shows nothing new but is food for thought given the matter of pyrgeometers on the Talkshop.

1st May was a particularly sunny day in southern England but cool, with a continuing wind from Norway via the North Sea.

Sir John Houghton: Objective scientist or driven ideologue?

Wikipedia tells us:

He was the lead editor of first three IPCC reports. He was professor in atmospheric physics at the University of Oxford, former Chief Executive at the Met Office and founder of the Hadley Centre.

He is the chairman of the John Ray Initiative, an organisation “connecting Environment, Science and Christianity”,^[1] where he has compared the stewardship of the Earth, to the stewardship of the Garden of Eden by Adam and Eve.^[2] He is a founder member of the International Society for Science and Religion. He is also the current president of the Victoria Institute.

Jon Jones alerted me to a press cutting this morning. I was amazed:

Chilbolton Observatory unofficial dataset, numeric and plots

Example data. Lidar is useful in identifying cloud layers, clear sky, it cannot though see multiple layers, where radar images if available are more useful. Click to open full size.

[UPDATE 2013/05/05,  archive release with corrections] An unofficial high resolution dataset has been derived from web published graphs running from 16th February 2013 to 20th April 2013 (less 23rd Feb), just over 60 days of data at about 2.3 minutes resolution for about 23 hours a day. The data includes atmospheric water parameters and thermal radiation parameters, all measured from surface level. Archive period includes the exceptionally cold March 2013. The weather hereabouts was cold but unlike most of the rest of the UK there was little snow, nor was the temperature very low.

‘Earth-like’ Blue Planets Discovered Orbiting Distant Star

From the Telegraph:

Two Earth-like planets thought to be covered in water have been discovered orbiting a distant star and may even have the right conditions to support life.

Astronomers believe the two ocean dominated worlds, which are around one and a half times the size of Earth, lie within the so-called Goldilocks zone around their star.

This is the distance from the star where it would be neither too hot nor too cold for there to be liquid water on the planet surface.

Scientists using Nasa’s Kepler space telescope, which has been searching for habitable planets outside our solar system, spotted the two planets orbiting a star called Kepler-62 1,200 light years away.

Wayne Jackson: Atmospheric mass not composition is the key to the greenhouse effect

Following the marathon thread about Willis Eschenbah’s ‘steel greenhouse’ concept, Wayne takes the discussion of real planets and the way their energy balance points are considered in a new and promising direction.

Earth TSI, 1362 W/m² / 4 = 340.5 * (1-0.3022 Bond albedo) = 237.6 OLR & also solar input

Venus TSI 2614 W/m² / 4 = 653.5 * (1-0.9000 Bond albedo) = 65.35 OLR & also solar input

Earth surface temperature 289.1 K per TFK2009

Venus surface temperature 735.4 K, 0.3°C greater than the VIRA (Venus Int’l Ref. Atm.) data

Robert Dull: Has ‘Perfect Storms’ solved AD 536 mystery?

From the Chronicle Journal:

Victoria Ahearn, The Canadian PressFriday, April 5, 2013 – 06:00TORONTO – American paleoecologist Dr. Robert Dull believes he’s pretty much solved the mystery behind a catastrophic global climate change event from the sixth century.As the new History series “Perfect Storms” shows, Dull has found solid circumstantial evidence that an eruption at El Salvador’s Lake Ilopango volcano was the cause of the so-called Dust Veil of AD 356, when a thick dust and ash cloud over the Northern Hemisphere cooled parts of the Earth and led to millions of deaths.
