‘Committed warming’ is defined here as the further change in global mean temperature after atmospheric composition, and hence radiative forcing, is held constant. (from box TS.9) Consider this simple example: humans emit CO2 until the year 2010, when the atmospheric concentration of CO2 reaches...
Analyses of observed and model data have linked interannual to multiannual fluctuations in global mean temperature to natural phenomena including the El Nino-Southern Oscillation (ENSO) and volcanic activity. On decadal and longer time scales, global temperature change in recent decades has also been ...
Intermediate scenario B was described as ‘‘the most plausible.’’ Scenario B has continued moderate increase in the rate of GHG emissions and includes three large volcanic eruptions sprin- Annual Mean Global Temperature Change: ΔTs (°C) Fig. 2. Global surface temperature computed for ...
The change in predictability of monthly mean temperature in a future climate is quantified based on the Community Climate System Model, version 4. According to this model, the North Atlantic overtakes the El Ni±o-Southern Oscillation (ENSO) as the dominant area of seasonal predictability by 2095...
This test suggests that the inflated high correlation between CO_2 and temperature(mean R~2=0.765-0.024=0.741) used in reports from the Intergovernmental Panel on Climate Change(IPCC) was very likely produced during data correction and processing. This untrue global monthly mean temperature has ...
New data are presented on the changes of mean global surface air temperature and annual precipitation over extratropical continents of the Northern Hemisphere. Global warming occurred during the last century with a mean trend of 0.5°C/100 years. It is shown that for the same period the annual ...
10.6.1 Temperature Extremes Consistent with the notion of a warming climate, for which we know that shifts in the mean cause corresponding or larger changes in the tails of the distribution (Kharin and Zwiers, 2005, Katz, 1999), and with studies that have already detected anthropogenically-drive...
There are also regional differences in temperature response at the same warming threshold over the TP under RCP4.5 and RCP8.5 scenarios. The differences of annual and seasonal mean temperature between the two periods when global warming reaches 1.5 ℃ and 2 ℃ under two scenarios all exceed 0.5 ...
Regional temperature and precipitation changes under high-end (≥4°C) global warming Climate models vary widely in their projections of both global mean temperature rise and regional climate changes, but are there any systematic differences...

We estimate seasonal global mean sea level changes using different data resources, including sea level anomalies from satellite radar altimetry, ocean temperature and salinity from the World Ocean Atlas 2001, time-variable gravity observations from the Gravity Recovery and Climate Experiment (GRACE) missi...
