And what of the satellites that have measured an increase in solar activity? What of the evidence that Mars and other planets in the solar system are also heating up?

For the latter question, see point #2 in my profile. For the former, which satellites and how much?

"We're in the maximum phase of the solar cycle now," says Dr. David Hathaway, a solar physicist at the NASA Marshall Space Flight Center, "and it will probably persist for another year or more. This one is somewhat smaller than the last two maxima in 1989 and 1979, but it's definitely bigger than average."

SOHO
Something similar happens to Earth's atmosphere every 11 years when the sunspot cycle nears maximum. As solar activity increases, extreme ultraviolet radiation (EUV) heats our planet's gaseous envelope, causing it to swell and reach farther into space than normal. While puffed-up marshmallows can lead to tooth decay, our puffed-up atmosphere vexes satellite operators with a different kind of problem -- orbit decay.

SORCE
Many researchers believe the steady rise in sunspots and faculae since the late seventeenth century may be responsible for as much as half of the 0.6 degrees of global warming over the last 110 years (IPCC, 2001).

Another trend scientists have picked up on appears to span several centuries. Late 17th century astronomers observed that no sunspots existed on the Sun’s surface during the time period from 1650 to 1715 AD. This lack of solar activity, which some scientists attribute to a low point in a multiple-century-long cycle, may have been partly responsible for the Little Ice Age in Europe. During this period, winters in Europe were much longer and colder than they are today. Modern scientists believe that since this minimum in solar energy output, there has been a slow increase in the overall sunspots and solar energy throughout each subsequent 11-year cycle.

Does this constitute evidence in your book?
