Changes in temperature affect equlibrium constants, so delta G can be affected in a couple of ways.
G=-rTlnKeq - so as the temperature increases, the delta G usually gets more (-), or spontaneous.

Also, G=H-TS
Changes in temperature can make G more negative and the reaction more spontantous. If in the above equaiton S is (-), then increasing temperature won't make it more spontaneous (because -TS) term becomes more positive.
