An independent organization of leading scientists and journalists researching and reporting the facts about our changing climate and its impact on the public.
Climate Central surveys and conducts scientific research on climate change and informs the public of key findings. Members of the Climate Central staff and board are among the most respected leaders in climate science.
We've talked before about the sun-climate connection, which is often invoked as the great missing link in understanding climate change. But none of that answers the question of whether the current warming of the climate is mostly attributable to a changing sun, or whether, as the vast majority of climate scientists have shown, is due mostly to greenhouse gases generated by human civilization. You might think this would be good news for people who insist global warming has more to do with the sun than with driving SUV's and burning coal.

When the sun gets brighter or dimmer, the relative amounts of those different kinds of light change.
Over the past century, the Sun has, scientists believe, gotten just a bit brighter overall — which is why climate scientists have always acknowledged that some of the warming in the 20th century, though not much of it, really has been due to the sun.

What Haigh and her colleagues found was that between 2004 and 2007, although the sun overall got a little dimmer, the amount of light in the visible part of the spectrum got brighter, contributing to global warming. In other words, global warming would have been even greater, according to this hypothesis, if the sun hadn't brightened.
