[Response: weaker cosmic ray flux - > fewer low clouds - > decrease in sunlight reflected back to space), then you need to explain why the night temperatures appear to increase faster then day temperatures (for any amplification mechanism involving te albedo, you'd expect the opposite, as there is no sunlight to reflect on the dark side of the planet...).

As for the validity of the cosmic ray flux, the Rahmstorf et al. critique on the Milky Way spiral arms / ice - age epoch work on did not contain any valid points (see http://www.sciencebits.com/ClimateDebate), this is contrary to the Royer et al. critique which did contain an interesting point.

So Mr. Lambert puts in this skeptical view based on this research, BUT fails to ALSO comment whether CO2 has an equally significant ELECTRICAL significance, and, hence, has a dependant relationship with the cosmic ray flux.

The observed period of the occurrence of ice - age epochs on Earth is 145 ± 7 Myr (compared with 143 ± 10 Myrs for the Cosmic ray flux variations),

Agreed, but if it isn't CO2 [based on this absence of a temperature corrolation] then we would be wise to assume the above solar irradiance, solar UV irradiance, cosmic ray flux, Milankovitch cycles etc as being the most likely culprit.

7.4.5 Impact of Cosmic Rays on Aerosols and Clouds 43 44 High solar acti0vity leads to variations in the strength and three - dimensional structure of the heliosphere, 45 which reduces the flux of galactic cosmic rays (GCR) impinging upon the Earth's atmosphere by increasing 46 the deflection of low energCosmic Rays on Aerosols and Clouds 43 44 High solar acti0vity leads to variations in the strength and three - dimensional structure of the heliosphere, 45 which reduces the flux of galactic cosmic rays (GCR) impinging upon the Earth's atmosphere by increasing 46 the deflection of low energcosmic rays (GCR) impinging upon the Earth's atmosphere by increasing 46 the deflection of low energy GCR.

Reconstructing cosmic ray fluxes The starting point of [Shaviv and Veizer, 2003] is a reconstruction of cosmic ray fluxes over the past 1,000 m.y. based on 50 iron meteorites and a simple model estimating cosmic ray flux (CRF) induced by the Earth's passage through Galactic spiral arms -LRB-[Shaviv, 2002; Shaviv, 2003]-RRB-.

I went through that link in that statement and don't see anywhere Shaviv agreeing that Cook et al. correctly classified his abstract of his paper «On climate response to changes in the cosmic ray flux and radiative budget».

They are most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on the earth's atmosphere.

The latter analyses frequently focus on sudden high - magnitude reductions in the cosmic ray flux known as Forbush decrease events.

Cosmic ray flux is also shown (red line, values on right - hand axis), calculated from the Climax Colorado (39.37 ° N, − 106.18 ° W, 3400 m, 629 mb, 2.99 GeV) and Moscow (55.47 ° N, 37.32 ° E, 200 m, 1000 mb, 2.43 GeV) neutron monitor datasets.

There is no direct correlation or coincidence over observed time to indicate that it is «most likely caused by variations in the solar wind and associated magnetic fields that affect the flux of cosmic rays incident on the earth's atmosphere»

Solar cycles of magnetic variability result in changes in the luminal spectra of the sun, the properties of the solar wind, and the flux of galactic cosmic rays incident on Earth's atmosphere.

The Singer report has many valid points — that the IPCC has repeatedly published erroneous or misleading graphs, that the IPCC completely ignored groundbreaking research into the connection between high energy cosmic ray flux and climate, and that the «fingerprint» test of the pattern of mid-latitude warming casts doubt on climate models, the anthropogenic effect, or both.

A joint analysis of paleodata on variations in cosmic ray fluxes, solar activity, geomagnetic field, and climate during the period from ∼ 10000 to ∼ 100000 years ago has been performed.

It is well known that the solar magnetic cycle strongly modulates the cosmic ray flux observed on Earth and there have been a number of papers concerning apparent correlations between cosmic rays and cloud cover.

A few groups pursued the study of possible mechanisms, for example elaborating theories of how changes in the atmosphere's electric circuit, which varies with the flux of cosmic rays, affected precipitation in the Arctic, Ram et al.
