Global Warming?

"Climate scientists have known for many years that the energy output from the Sun varies and believe it or not, when the Sun is putting out more energy, the Earth heats up and when the Sun cools down, so does the Earth. What appears to be so simple is actually much more complex as the Sun can vary its output differentially in the various portions of the electromagnetic spectrum. For example, the Sun can actually increase its production of gamma rays while decreasing the level of infrared emission, and these patterns of energy output can reveal themselves quite differently in terms of response of Earth’s climate."
