Sigma typically means "Total" or "All" It's used often in Statistics equations. So Just as [Delta]T would be "Change in Temperature", [Sigma]T would mean "total temperatures". So if you had 10 temperatures and the total change was 25 degrees C? you could find the average change in T by doing... [Delta]T divided by [Sigma]T. Make more sense, now?
