Narrative:

After departing ZZZ during climb out; we received a right cowl anti-ice caution message (abnormal 11-2). Although our tat was 11 degrees C; we were in IMC and after conferring with maintenance control and dispatch; I decided it best to return to ZZZ due to possibility of encountering icing conditions if we climbed. We diverted back to ZZZ; declared an emergency because we were landing overweight at 48490 pounds. I contacted maintenance control and they told me to land at a rate below 300 FPM during the landing. I landed with a rate around 300 FPM; landed without further incident. We xferred the controls from first officer to captain for the landing.
