It is due to the gravitational redshift induced by photons falling into and climbing out of very dense regions of space, called potential wells[?], in between the Earth and the surface of last scattering[?] (close to the particle horizon[?]). The naive sachs wolfe[?] effect is also due to gravitational redshift, but is the effect only at the surface of last scattering[?] itself.
