Table 3.1 shows best estimates and likely ranges for global average surface air warming for the six SRES marker emissions scenarios (including climate - carbon cycle feedbacks). (ipcc.ch)
Regarding surface air warming in the 21st century, the best estimate for a «low scenario» is 1.8 degrees Celsius with a likely range of 1.1 to 2.9 degrees Celsius (3.2 degrees Fahrenheit with a likely range of 2.0 to 5.2 degrees Fahrenheit). (sciencedaily.com)
This animation shows how the same temperature data (green) that is used to determine the long - term global surface air warming trend of 0.16 °C per decade (red) can be used inappropriately to «cherrypick» short time periods that show a cooling trend simply because the endpoints are carefully chosen and the trend is dominated by short - term noise in the data (blue steps).
