Watt Flashlight
Have you seen “Solar Force” on National Geographic’s, Naked Science?
It airs again on November 6th & the 8th. It says that scientist know that the sun has been the major climate driver in the past, but scientist have not been able to figure out why a .15%variation of intensity has such a profound effect on the climate. They show a huge 1365 watt lamp shining on one square meter to simulate the suns effect on the surface of the Earth and then turn on a little flashlight to simulate the variation of the sun’s intensity. They say that the change isn’t enough. Then they show two solar physicists and one atmospheric physicist that each have a theory about the possible mechanisms that the sun could change our climate in a more powerful way.
The atmosperic physicist was Neil Arnold. One Solar Physicist was Svensmark and the other was female, but I don’t remember her name. She talked about the much higher changes in UV.
Hi Doc, no I’m not a lawyer. National Geographic is who “post this stuff”.
Thank you for mentioning the show. I will look for it.
I understand that the change in solar variation is not great. I have also heard scientists discuss possible mechanisms for solar amplification, especially in the polar regions. One of the mechanisms had to do with cosmic rays, but other mechanisms were mentioned as well.
I look forward to watching the show to see what mechanisms they put forward. If you can tell us the names of the scientists on the show, it would be helpful.
