Low emissions scenario

The wider range is from the lowest to highest value for all emissions scenarios and three (10, 50, and 90%) probability levels for each 30-year time period.

  • Under low emissions, the central estimate of increase in winter mean temperature is 2.3ºC; it is very unlikely to be less than 1.3ºC and is very unlikely to be more than 3.5ºC. A wider range of uncertainty is from 1.3ºC to 4.8ºC.

  • Under low emissions, the central estimate of increase in summer mean temperature is 2.8ºC; it is very unlikely to be less than 1.3ºC and is very unlikely to be more than 4.6ºC. A wider range of uncertainty is from 1.3ºC to 7.3ºC.

  • Under low emissions, the central estimate of increase in summer mean daily maximum temperature is 3.6ºC; it is very unlikely to be less than 1ºC and is very unlikely to be more than 6.6ºC. A wider range of uncertainty is from 1ºC to 10.1ºC.

  • Under low emissions, the central estimate of increase in summer mean daily minimum temperature is 2.8ºC; it is very unlikely to be less than 1.1ºC and is very unlikely to be more than 4.9ºC. A wider range of uncertainty is from 1.1ºC to 7.8ºC.

  • Under low emissions, the central estimate of change in annual mean precipitation is 0%; it is very unlikely to be less than –6% and is very unlikely to be more than 8%. A wider range of uncertainty is from –10% to 12%.

  • Under low emissions, the central estimate of change in winter mean precipitation is 15%; it is very unlikely to be less than 5% and is very unlikely to be more than 30%. A wider range of uncertainty is from 3% to 50%.

  • Under low emissions, the central estimate of change in summer mean precipitation is –17%; it is very unlikely to be less than –35% and is very unlikely to be more than 3%. A wider range of uncertainty is from –51% to 3%.
