Huge Defunct Satellite Will Fall to Earth Around Sept. 24, NASA Says
NASA spokeswoman Beth Dickey confirmed with SPACE.com earlier today that the reason UARS is expected to fall early in its re-entry window is because of the sharp uptick in solar activity. Solar effects from the sun can create an extra drag on satellites in space because they can heat the Earth's atmosphere, causing it to expand, agency officials have said.

Would this be the Atmospheric Diurnal Bulge (solar heating from the top down)causing the extra drag on the sat. What? Solar heating of the atmosphere not caused by GHGs?
