Roy Martin: Critique of Konrad Hartmann’s pressure-temperature experiment

By Roy Martin, 31 Jan, 2012 It appears that the conclusions of this experiment are incorrect, that it has not proved that the higher temperature reached in a container at a constant higher pressure, relative to an identical container at a lower constant pressure, is in fact simply due to the higher pressure. Such a [...]

Back to basics 2: Lapse rates and atmospheric stability

Introduction A large amount of cloud formation and much of the dynamic behaviour of the atmosphere depends upon vertical movements of air. The tendency of air masses to move up or down is termed its stability. Unstable air masses are prone to vertical movements, while stable air resists vertical motion. The stability of air is [...]

Planetary cloud albedo level is a function of solar energy absorption and atmospheric pressure

OK, I think we have more clarity on the difference between N&Z and Harry Dale Huffman’s interpretation of Venus and Earth data. > On 1/29/2012 12:34 PM, Rog Tallbloke wrote: > > Hi Ned, > > I think I’ve managed to get Harry Dale Huffman to state what > the key point he has at [...]

1000 scientists and counting boycott Elsevier journal publishing

From El Reg H/T Tim Channon. The ongoing world protests against SOPA, PIPA, and ACTA have helped inspire a revolt among scientists over the role of academic publisher Elsevier and its business practices. British mathematician Tim Gowers kicked-started the campaign with a scorching blog post outlining numerous complaints against the publisher, which sells over 2,000 [...]

The Mystery of Planet 8

  Neptune is the eighth and farthest planet from the Sun in the Solar System. Named for the Roman god of the sea, it is the fourth-largest planet by diameter and the third largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is [...]

Another X-class solar flare cycle 24

Hat tip to Vuk. We’ve not had a solar activity thread recently so when Vuk points at spitzundsparken it seems a good idea.

Back to basics: History of the gas laws

Ned Nikolov says: January 25, 2012 at 11:54 am Richard M Where have we claimed that we replace the greenhouse effect with gravity? What we state is that the GH effect, when measured as a dimensionless number (Ts/Tgb), i.e. the relative thermal enhancement, is completely explainable by pressure. Is pressure a gravity? No! Pressure is [...]

Gavin Schmidt: Climate Homeopathy

Visit Cartoons by Josh With our renewed understanding of the omnipresent force of gravity, and its profound effect on the heat distribution in planetary atmospheres via the pressure gradient it causes we can start to appreciate the numbers involved. If there was no gravity and we wanted to change the pressure of our atmosphere from [...]

Greenhouse gases cool planets: Volcanos warm them

Thinking about the logical outcomes of Nikolov and Zeller’s ‘Unified Theory of Climate‘, a couple of ideas emerge which turn conventional climate science ‘wisdom’ on its head. It has long been believed that ‘greenhouse gases’ cause warming of the planet’s surface. While this may be true at the local level near the surface at certain [...]
