Urban climate change has short- and long-term implications for decision-makers in urban development. The problem for this important metropolitan regional of population and economic value is that there is very little usable information on climate change. Cities in industrialized countries also emit most greenhouse gases (GHC). This research about urban climate change in Bali uses Conformal Cubic Atmospheric Model (CCAM) base on history IPCC AR5 as baseline climatology average (1971-2000), climate projections with RCP45 scenario (2040-2069), while the anomaly (climate change) is the difference between RCP45 and history. The result are the history of temperature between 22.5-27.5 oC, and RCP45 between 25.5-29.5 oC. The temperature anomalies can be seen in most of northern Bali that increased by about 1.6 to 2.9 oC. There is a reduced humidity tendency (drier) in most parts of Bali, especially the northern part of Bali, while a small portion in the south increase moisture (wetter). The comfort index of Bali region in history is still relatively comfortable (20-26), but on the condition RCP45 there is no comfortable area with index more than 26 (hot and dry). This research is expected to be useful to help the government make good urban planning.
