Effects of a different CMBR temperature?

[vicky_molokh]

Greetings, all!

I'm curious: what would be the implication of a setting having the Cosmic Microwave Background Radiation temperature higher than in ours? Currently I'm mostly see differences in calculating blackbody temperatures of everything, and in detection modifiers for objects in space, but what would those changes be, based on a given new value of the temperature?

What other consequences would it have? Would a gradual or sudden change produce results significantly different from it 'always being that way' throughout the aeons?

Thanks in advance!
