No Link Between Cosmic Rays and Global Warming:

"The scientific consensus is in: human-produced carbon dioxide is causing a rise in temperatures across the planet. There are still those who reject the evidence that humans have an impact on global temperatures, and instead maintain that natural processes are at the root.

"One of these natural causes, they say, could be from cosmic rays.

"Sloan and Wolfendale reviewed the cosmic ray connection to global warming, and found several different ways that discount the explanation. Of course, no matter how good their evidence, for some people this is a political matter now - no amount evidence will ever be enough."
