found that numerous hot spots have already exceeded the critical 2 degree Celsius mark, far above the global average. In general, higher latitudes, such as the Arctic, are warming faster than mid-latitude regions.Reducing global temperatures by 0.5 degrees.Limiting warming to no more than 1 degree Celsius above preindustrial averages.
