Earth's recent warming trend might in part be due to a lack of starlight reaching our planet, a new study suggests. But other scientists are not so sure.
According to a theory proposed a decade ago, when a star explodes far away in the Milky Way, cosmic rays—high-speed atomic particles—go through the Earth’s atmosphere and produce ions and free electrons.
The released electrons act as catalysts and accelerate the formation of small clusters of sulfuric acid and water molecules, the building blocks of clouds. Therefore, cosmic rays would increase cloud cover on Earth, reflecting sunlight and keeping the planet relatively cool.
However, because the Sun’s magnetic field—which shields the Earth from these rays—doubled in intensity during the last century, there has been a reduction in cloudiness, a possible contributor to Earth’s warming.
Scientists at the Danish National Space Center mimicked chemistry of the lower atmosphere in a large reaction chamber. They created a mixture that contained gasses at realistic concentrations and used an ultraviolet lamp to act as the Sun.
Microscopic droplets, precursor to clouds, started floating in the air of the reaction chamber.
“We were amazed by the speed and efficiency with which the electrons do their work of creating the building blocks for the cloud condensation nuclei,” said team leader Henrik Svensmark, Director of the Center for Sun-Climate Research at the Danish National Space Center. “This is a completely new result within climate science.”

This explains the frigid temperatures on Venus. Lots of cloud cover, big greenhouse effect = plummeting temperatures. Is this new theory?
Yes, the doubling of the Sun's magnetic field strength is miniscule compared to the power of SUVs ~ MSM simply won't talk about it.

That would be Karl's death rays from the planet Zog. Heating up the earth to make buttloads of money in the refrigeration industry. To sell vast quantities of air conditioners.
Check the cloud types....
Proabaly more than once. 8^)
cosmic rays aren't "rays".
However, they can probably spell.
Cosmic Rays Linked to Global Warming... and George Bush linked to cosmic rays.
This is a total duh!
Cosmic rays also play a role in lightning formation (just how that affects the ecology I wouldn't guess).
But, but, but … I thought it was all Bush’s fault!
Bush's fault.
If a force of cosmic nature causes "global warming" then the grant money stops flowing and they can't use it to foster a technophobic agenda.
Clearly this is Bush's fault. Clinton tried to stop the increase in the Sun's magnetic field. He tried, and he failed, but at least he tried!
STOP PLATE TECTONICS!!!!!!!!!!
