sun blamed for global warming

Although I tend to be suspicious of articles that try to mitigate the human component of global warming, I couldn't help but laugh at the title of this article. We're blaming the sun for global warming. Good job, Einstein.

I was not surprised to see, on reading through the article, scientific agreement on the likelihood that changes in the sun are not enough to explain the dramatic climate changes we're seeing on earth and that most of the changes are probably attributable to human activity. However, I was intrigued to read that Mars is experiencing a warming trend as well. Maybe, if Mars warms up enough, we can all just move there? That's what John Travolta says, anyway.
