How about some space-based evidence for global warming?
A technique pioneered by Leonardo da Vinci for measuring the amount of light reflected on to the dark side of the Moon has indirectly supported the idea that global warming has increased during the past five years.
Scientists at the New Jersey Institute of Technology in New York have refined Leonardo's method of observing "earthshine", the light reflected from the Earth on to the side of the Moon that is never illuminated by the Sun, to investigate how much of the Sun's energy is being bounced back into space.
Philip Goode, the leader of the team of scientists, said that reflectance, or "albedo", was a key factor in determining whether the Earth would continue to warm up as the greenhouse effect worsened.
"The Earth's climate is driven by the net sunlight it absorbs. We have found surprisingly large - up to 20 per cent - seasonal variations in the Earth's reflectance. Further, we have found a hint of a 2.5 per cent decrease in Earth's albedo over the past five years."

Steven Koonin, professor of theoretical physics at the institute and a member of the team, said that looking at earthshine on the Moon over a long period of time was perfect for monitoring any changes in the Earth's climate, thus highlighting any global warming.

Of course, they must be hysterical left-wing doom-mongers. Theoretical physicists are known for taking irrelevant stances based on preconceived ideas, after all, and maths is so subjective... |
