Just a thought, but how about Milky Way Galaxy spiral arm warming?
I'll try to explain -pardon my generalizations and shoddy science
The earth spins on a tilted axis. Our orbit of the sun is also tilted. Likewise, the spiral arms of our galaxy are tilted. Like a warped record (for
those of us old enough to remember leaving our vinyl records in the sun) everything wavers up and down from the central core.
Right now, the spiral arm our solar system occupies is more in line with the center of the galaxy than it has been in a long, long time. Could
radiation from the galaxy's core result in a warmer planet, the same way radiation from the sun causes summer and winter? I think it's possible.
