Ring Around the Planet?

When I was a physics major for two years of college (before I came to the humbling realization that in the end a career in physics meant doing Math 24/7 for the rest of my days) I loved the theoretical side of things. Loved talking about quantum mechanics, relativity, and the really weird implications of modern theory. Like the idea that while it was impossible for you and me, quantum teleportation (going from point X to point Y without ever occupying any point in between) was a common occurrence. But I never confused "cool theory" and "workable plan."

A new article in LiveScience proves that some science folks, however, have no problem confusing theory and practical reality. Their solution to combat global warming is not to reduce emissions, sequester excess greenhouse gasses, or plant more trees. Nope. They want to create a HUGE "ring around the planet." Theoretically, this Saturnine planetary fashion accessory would block excess solar radiation from the equatorial regions and thus cool the planet. And all for the low, low price of $500 billion to $200 trillion.

Personally, I would prefer a large sombrero or cowboy hat to shield the planet. Just think! It would give us all an excuse for a siesta each day!
