The emphasis this week seems to be on the sun, and the fact that maybe its really the sun which has been driving climate change after all. That's wha… - Anthony Watts

"Global warming" suggests a steady linear increase in temperature, but since that isn't happening, proponents have shifted to the more universal term "climate change," which can be liberally applied to just about anything observable in the atmosphere.

And finally we have this, this discovery that Earth's magnetic field can be ripped open and our atmosphere laid bare to the solar wind, much like Mars. Magnetism is underrated in the grand scheme of things, in my opinion. We'd do well to pay more attention to magnetic trends in our corner of the universe and what effects it has on Earthly climate.

As I've always said, the sun is the "Big Kahuna" of climate change on Earth. Everything else is secondary, even though man's opinion of his own self importance in the scheme of things often dictates otherwise.
