The author (a Danish scientists who did much of the key work in this area) has been able to produce the effect in the laboratory and has documented the statistical relationship with low level clouds and surface temperatures. Many climate episodes over millions of years appear to be explained by cosmic ray effects. The theory also explains how differing number of sun spots come to affect year to year climate change on earth.
The later makes this a key book for those interested in the global warming debates, especially since so much of the research is recent. This makes it a must read since the evidence is not yet in most other popular discussions of climate change.
When stars die, they do so in supernova explosions that emit cosmic rays, which create ions, which form clouds. Low clouds - less than 3000 metres above the surface - keep the planet cool. The less active the sun is, the more cosmic rays get through to the earth, and so the more clouds there are to cool the earth.
The Danish National Space Centre's SKY experiment showed how cosmic rays set free electrons which then catalysed the clubbing together of sulphuric acid molecules, the most important source of condensation nuclei. These cosmic rays have varied since the world began; their influx depends largely on where the earth is in the galaxy in our orbit around the centre of the Milky Way. When the earth is in dark regions with few stars where the rays are scarce, the climate is warm. When the earth is in bright regions where the rays are intense, the climate is cool.
The medieval warm period of 1000-1300 was followed by the cool periods of 1300-60 and 1450-1540, and a worse one, the little ice age of 1645-1715, then another cool period in 1790-1820. The peak of the little ice age was 1700, which coincided with the Maunder Minimum, when the sun's magnetic activity was very low, reducing its ability to shield the earth from cosmic rays.
In the last century, the sun's magnetic field doubled in strength, reducing the cosmic rays and so the clouds, thus heating up the earth by 0.70C from 1900 to 2005, 70% of the 20th century's warming.Read more ›
But the climate on planet Earth has been changing for roundly 4 billion years, within quite wide limits. There have been periods when most of the land surface was covered by ice caps, periods when even the polar areas were semi-tropical, and just about every state in between. There must be something big driving the system, the theories based on manmade carbon emissions (a recent phenomenon) do not seem to have much to offer, and the cosmic ray theory starts sounding better when it is broken down step by step.
#The starting point is low-lying clouds, which serve to deflect incoming solar energy and thereby cool things down. Caveat: the massive and intensely white ice cap of Antarctica is even more reflective than the clouds, so in that one area (but not Greenland, Siberia, etc.) clouds warm things up.
#Water vapor in the atmosphere will produce more clouds if there are nuclei (or specks) in the air to facilitate the process. The formation of nuclei is in turn facilitated by cosmic rays (high energy, charged particles that bombard our solar system from outer space). Hey, remember how energetic atomic particles were detected at one time with cloud chambers that would display vapor trails triggered by their passage.
#Cosmic rays originate from the explosion of dying stars; they are not equally spread through the universe nor constant over time. As our sun makes it way around the Milky Way galaxy, the volume of cosmic rays encountered waxes and wanes.Read more ›
