It looks as if the curve has been readjusted at some stage, but it is then a bit strange that the curve representing the global lower cloud cover doesn't seem to have been re-scaled: the difference between maximum and minimum is about 3 % in both figures (it's annoying that the vertical axis for the cloud cover are given in different units in Fig. 2 & 3).

On the possibility of a changing cloud cover «forcing» global warming in recent times (assuming we can just ignore the CO2 physics and current literature on feedbacks, since I don't see a contradiction between an internal radiative forcing and positive feedbacks), one would have to explain a few things, like why the diurnal temperature gradient would decrease with a planet being warmed by decreased albedo... why the stratosphere should cool... why winters should warm faster than summers... essentially the same questions that come with the cosmic ray hypothesis.

Henrik Svensmark and others have shown a long - term correlation between solar activity and global temperature and have hypothesized that this results from changes in galactic cosmic rays leading to changes in cloud cover.

The impact of these changes in cloud cover can account for the variations in HadCRUT4 global average temperature anomalies and the divergence between land and sea temperatures.

Some studies have shown co-variation between GCR and low - level cloud cover using global satellite data over periods of typically 5 — 10 years (Marsh and Svensmark, 2000; Pallé Bagó and Butler, 2000).

Some studies have shown co-variation between GCR and low - level cloud cover using global satellite data over periods of typically 5 — 10 years (Marsh and Svensmark, 2000; http://dx.doi.org/10.1103/PhysRevLett.85.5004

Brown, Short - term changes in global cloud cover and in cosmic radiation, Journal of Atmospheric and Solar - Terrestrial Physics Volume 70, Issue 7, May 2008, Pages 1122 - 1131 See: Whiterose Online copy «There is an association between short - term changes in low cloud cover and galactic cosmic radiation over a period of several days.

Spencer / Braswell and Lindzen / Choi look at the relationship between changes in ocean heat, cloud cover (directly affecting the amount of heat lost to space), and global surface temperature over recent decades.

The uncertain effect of feedback between climate and clouds is one of the largest obstacles to producing more confident projections of global climate.

Our long - term analysis of MISR data finds no statistically significant correlations between cosmic rays and global albedo or globally averaged cloud height, and no evidence for any regional or lagged correlations.

A number of studies have highlighted relationships between low - cloud amount changes under global warming and modeled variations of low clouds with changes in specific meteorological conditions (such as surface temperature, inversion strength, subsidence)(Qu et.

Just as obviously, the relationship between CO2 and global temperatures (and clouds) is from weak to lame, at best - confirming evidence here.

Consequently, a small direct current is able to flow vertically between the ionosphere (which is maintained at a potential of ~ 250 kV due to the global net effect of charging from thunderstorms and electrified clouds) and the Earth's surface.

When other researchers plugged in a more comprehensive data set, the correlations Svensmark found between cosmic radiation and the Earth's global cloud cover broke down.

We disagree with this conclusion, arguing that when cloud properties are considered as a global average (Fig. 3) or over areas of frequent cloud cover (Fig. 4), the strong anti-correlation between low and middle - to - high level cloud is both clear, and statistically significant.

«The overall slow decrease of upwelling SW flux from the mid-1980's until the end of the 1990's and subsequent increase from 2000 onwards appear to caused, primarily, by changes in global cloud cover (although there is a small increase of cloud optical thickness after 2000) and is confirmed by the ERBS measurements... The overall slight rise (relative heating) of global total net flux at TOA between the 1980's and 1990's is confirmed in the tropics by the ERBS measurements and exceeds the estimated climate forcing changes (greenhouse gases and aerosols) for this period.

Using their recently developed methods for removing spurious artefacts from historic satellite cloud records, Joel Norris et al. have constructed a record of the global pattern of cloud changes between the 1980s and the 2000s.

It is this change in cloud that dominates ENSO modulated global energy dynamics — everything else merely redistributes energy between atmosphere and oceans.

Svensmark et al. (2009) found large global reductions in the aerosol Ångström exponent from AERONET, liquid water path from SSM / I, and cloud cover from MODIS and ISCCP after large Forbush decreases, but these results were not corroborated by other studies who found no statistically significant links between GCR and clouds at the global scale (Calogovic et al., 2010; Kristjánsson et al., 2008; Laken and Calogovic, 2011).

Subsequently they claim that the rising reflectance of the Earth has not led to a reversal of global warming because the difference between low and middle - plus - high ISCCP clouds has increased in the last four years.

Recent work in modelling the warm climates of the Early Eocene shows that it is possible to obtain a reasonable global match between model surface temperature and proxy reconstructions, but only by using extremely high atmospheric CO2 concentrations or more modest CO2 levels complemented by a reduction in global cloud albedo.

On the other hand, Gavin Schmidt of NASA GISS, one of the topmost scientists involved in the Catastrophic Anthropogenic Global Warming cause, in a recent paper clearly asserts that: • 75 % of the Greenhouse effect is attributable to water vapour and clouds • 100 % of the increase in CO2 emissions since 1850 (110 ppmv) is Man - made Following these numbers through and accounting for the effect of other Greenhouse gases results in a Man - made temperature rise between 1850 and 2010 of 2.21 °C.
