Ever since the 2011 CLOUD experiment at the European Organization for Nuclear Research (CERN), alarmists have tried to denigrate the results, claiming it’s a myth that cosmic rays can affect global warming. Some alarmists web sites, such as Skeptical Science, have made this claim.
In fact, the CLOUD experiments could drastically alter the entire global warming and climate change debate, which is why the alarmists’ have so vehemently attacked the concept that cosmic rays could affect cloud cover and global warming.
In the late 1990s, Danish scientists proposed that the sun could affect the number of cosmic rays entering the Earth’s atmosphere, and that cosmic rays could affect cloud cover and temperatures.
Mr. Jasper Kirkby, a CERN scientist, told the scientific press in 1998, “The theory will probably be able to account for somewhere between a half and the whole of the increase in the Earth’s temperature that we have seen in the last century.”
That’s a powerful concept, that cosmic rays could account for half, and possibly all of the temperature rise over the past century.
Mr. Kirkby, after considerable resistance from alarmists in government, finally persuaded the CERN establishment to conduct the CLOUD, for “Cosmics Leaving Outdoor Droplets” experiment.
The initial reports from the 2011 CLOUD experiment established that cosmic rays entering the atmosphere could create clouds.
But recent reports concerning the 2014 experiments have gone much further, and established two important findings.
First, the new report shows that a combination of cosmic rays from space and gases emitted by trees can create clouds, without the need for man-made pollution. Earlier, it was thought that man-made pollution was important for cloud formation.
This affects all the computer projections that have been made about temperature rise.
Low-level cloud cover affects temperatures by casting a shadow on the Earth’s surface and by reflecting sunlight back into space.
More low-level cloud cover results in lower temperatures. Less cloud cover results in higher temperatures.
The IPCC computer models made assumptions about the extent of cloud cover prior to the industrial revolution, assuming there were fewer clouds because there was less pollution.
The end result is that greenhouse gases aren’t having as great an effect on temperature rise as originally believed: “Ton for ton, they may not be quite as potent in producing future warming.”
This means the models have been overstating future temperature rise.
The second result of the CLOUD experiment shows that cosmic rays may have a greater effect on cloud formation than initially thought: “Ions produced in the atmosphere by galactic cosmic rays are found to enhance the formation, [i.e., multiply] the rate of these particles [needed for cloud formation] significantly.”
The CERN website says the extent of these findings are unknown, and infers they may be slight, but it’s an irrefutable fact that the science isn’t settled.
The end result of the latest CLOUD experiments show: (1) That the models used by the IPCC to predict future temperatures are overstating temperature rise to some extent, and (2) That cosmic rays have a greater effect on low-level cloud formation than previously thought.
This provides increasingly strong evidence that atmospheric CO2 is not the primary cause of global warming, and that the sun, by its effect on the number of cosmic rays entering the Earth’s atmosphere, is more likely to be the primary cause of global warming and climate change.
It’s clear the science is not settled, and there is strong evidence that science is proving that atmospheric CO2 is not the cause of climate change.
