Ok, this one is also brought to you by Discover Magazine, a (somewhat) dissenting voice regarding global warming (another clue regarding the change in editorial policy, that and the free DVD with a Shell oil infomercial bundled with the magazine). None the less a valid argument:
During the interview the guy says that he thinks that solar activity (with the mechanism he is theorizing) should be included (to the CO2 effect) in weather simulations regarding global warming.
The question I have is exactly how this activity affects cosmic rays; IIUC, all cosmic rays that pass through the heliosphere (that covers all the solar system) would be affected, but that would prevent cloud formation all over the planet, meaning that while the energy that comes directly from the sun can come in, at the other side of the planet the absence of those clouds would allow heat to escape. Am I understanding it in a very simplistic manner?
For reference I supply this old link, because the current edition isn't online yet.
Quote from: Henrik SvensmarkThe basic idea is that solar activity can turn the cloudiness up and down, which has an effect on the warming or cooling of earth's surface temperature. The key agents in this are cosmic rays (...). These energetic particles have to enter into what we call the heliosphere, which is the large volume of space that is dominated by our sun, through the solar wind, which is a plasma of electrons, atomic nuclei, and associated magnetic fields that are streaming nonstop from the sun. Cosmic rays particles have to penetrate the sun's magnetic field. And if the sun and the solar wind are very active -as they are right now- they will not allow so many cosmic rays to reach Earth. Fewer cosmic rays mean fewer clouds will be formed, and so there will be a warmer Earth. If the sun and the solar wind are not so active, then more cosmic rays can come in. That means more clouds[reflecting away more sunlight] and a cooler Earth
