GLOBAL COOLING FOR NEXT 50 YEARS?
Via Al Fin. I don't know if this is any more right than the warming scare. However just as the eco-fascist "cure for both global warming & the previous ice age scares weredestroying our technologhical society & preventing the common people flying on holiday, the true solution is more technology. If we had a space elevator or other cheap space access then putting up square miles of tinfoil parasols or mirrors would be highly practical.
Cosmic rays and chlorofluorocarbons (CFCs), both already implicated in depleting the Earth’s ozone layer, are also responsible for changes in the global climate, a University of Waterloo scientist reports in a new peer-reviewed paper.
In his paper, Qing-Bin Lu, a professor of physics and astronomy, shows how CFCs - compounds once widely used as refrigerants - and cosmic rays - energy particles originating in outer space - are mostly to blame for climate change, rather than carbon dioxide (CO2) emissions. His paper, derived from observations of satellite, ground-based and balloon measurements as well as an innovative use of an established mechanism, was published online in the prestigious journal Physics Reports.
”My findings do not agree with the climate models that conventionally thought that greenhouse gases, mainly CO2, are the major culprits for the global warming seen in the late 20th century,” Lu said. “Instead, the observed data show that CFCs conspiring with cosmic rays most likely caused both the Antarctic ozone hole and global warming....”
In his research, Lu discovers that while there was global warming from 1950 to 2000, there has been global cooling since 2002. The cooling trend will continue for the next 50 years, according to his new research observations. _

If the temperature of the earth is governed by how many solar flares the Sun puts out, and how much heat it radiates in general then if we are going into a period of global cooling then this should be a perfect time for spaceflight. Solar flares are the source of much of the radioactive particles that sweep by the Earth, and a reduction in solar flares would reduce the amount of radiation in near earth orbit making manned spaceflight easier.

It is certainly a good reason for space industrialisation since that would allow us to build orbital mirrors (miles across made of tinfoil so thin they would crumble in a gravity field). On the other hand warming would be an argument for solar shields (miles across made of tinfoil so thin they would crumble in a gravity field).
There refusal to consider technological solutions shows the eco-fascists up for mere Luddites.
