This change affects the entire radius, and additional uses of the ability are cumulative with the previous uses.
Still not sure that sounds quite right, but I think it's on the right track.
Streamlining a tad...
Control Temperature (Su): As a swift action, Aeraldoth can raise or lower the temperature by 10 degrees in a 100-foot-radius centered on him. Subsequent uses of this ability stack, so he could, for example, lower the temperature by a total of 20 degrees after two rounds.
