Man, its common knowledge that as a result of anthropogenic global warming through co2 emmissions, the earth is radiating less infrared energy out into the solar system. More energy is being retained in the atmosphere. "Just ask Al Gore, he'll tell ya." This reduction in earthly infrared radiation causes an infrared imbalance to occur in the solar system As a result, Jupiter's infrared radiation output increases, to make up the difference, and more great red spots develop.
So, yes it is our fault.
