Second,
with less cloud cover, more infrared radiation can escape to space, thereby creating a strong climate - stabilizing negative cloud feedback that prevents significant warming from increasing greenhouse gases.
Similarly, during periods of high solar activity,
less clouds form, leading to global warming.
According to the hypothesis, then, less cosmic radiation would mean
less cloud formation and, ultimately, warmer temperatures — precisely what was observed during the 20th century.
Also, in a cooling world one would
expect less clouds and rain at the higher latitudes and more at the lower latitudes.
The new findings, published in Science Advances, show that
less cloud cover and more summer sunshine allows increased solar radiation to reach the surface providing more energy for melting.
Kaufmann suggests that we have to reverse out of the cul de sac of sex for sex's sake and recombine it with love once more to make our experiences less chilly but also
less clouded by romantic illusions.
The physics is not difficult to understand by skeptics, nor objective scientists:
less clouds allow more sunshine to strike the Earth's surface (1980 - 1990s); more clouds decrease sunshine at surface (2000s).
One of them is that a warmer world has
less clouds not more clouds because of the jetstream shifting that I have mentioned.
Some investors will be in wait - and - see mode until the macro environment
becomes less clouded, while long - term offshore investors may see the inherent value of UK property in view of the weakening sterling and softening values, it points out.
To give just one hint that it is shockingly deficient in some respects, note that our oceans have
much less cloud cover than our land and are not limited by the availability of water, yet they can not even average 60 % of the productivity of our land.
It now appears clear that when the sun is active the jets are more zonal (east to west) with short lines of air mass mixing and
less clouds whilst when the sun is less active the jets are more meridional (waving north and south) with longer lines of air mass mixing and more clouds.
Higher trade winds
yield less cloud cover over the central and eastern tropical Pacific, which in turn yields more downward shortwave radiation, which in turn yields warmer water.
While pollution in some areas provides nuclei for water to condense on to form clouds, in other places there may be soot particles, which could absorb sunlight and cause the cloud to burn off (evaporate) during the day,
leaving less cloud to warm the night.
The increased clouding during periods of cosmic ray maxima and sun spot minima may ensue from decreased solar radiation and
lesser cloud dispersion.
In northern climates, lakes are losing their ice cover earlier, and many areas of the world have
less cloud cover, exposing their waters more to the sun's warming rays.
