The increase of radiative forcing matches the increase in ocean heat quite well don't you think jem? This is where the heat is coming from. The atmosphere heated up and transferred it's heat to the oceans. This is basic common sense stuff. Climate science 101. The key stat is that the forcing from CO2 increased 80% from 1 to 1.8 watts per square meter. Interesting stuff huh?
Changes in radiative forcing of long-lived greenhouse gases between 1979-2012.
This graph shows changes in radiative forcing of long-lived greenhouse gases between 1979-2012. These gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbon-12 (CFC-12), CFC-11, and fifteen other minor, long-lived, halogenated gases. The 15 other halogenated gases are CFC-113, tetrachloromethane (CCl4), trichloromethane (CH3CCl3); hydrochlorofluorocarbons (HCFCs) 22, 141b and 142b; hydrofluorocarbons (HFCs) 134a, 152a, 23, 143a, and 125; sulfur hexafluoride (SF6), and halons 1211, 1301 and 2402). The graph does not include other forcings, such as aerosols and changes in solar activity.
Summary
Total forcing in 1979 was 1.712 watts per square metre (W.m-2), and has steadily increased over time to 2.873 W.m-2 in 2012. Between 1979-2012, the largest contributors to radiative forcing have been CO2 and CH4. In 2012, the percentage contributions of each gas to total forcing was approximately:
CO2: 64%
CH4: 18%
N2O: 6%
CFC-12: 6%
CFC-11: 2%
15 minor gases: 4%
Forcing data are briefly summarized below. All the data are available in a later section as comma-separated values. The first value is the year, followed by forcing values (in W.m-2) for CO2, CH4, N2O, CFC-12, CFC-11, the 15-minor halogenated gases, and total forcing, respectively:
1979: 1.027, 0.419, 0.104, 0.092, 0.039, 0.031, 1.712
1980: 1.058, 0.426, 0.104, 0.097, 0.042, 0.034, 1.761
1990: 1.293, 0.472, 0.129, 0.154, 0.065, 0.065, 2.178
2000: 1.513, 0.494, 0.151, 0.173, 0.066, 0.083, 2.481
2010: 1.791, 0.504, 0.174, 0.170, 0.060, 0.106, 2.805
2012: 1.846, 0.507, 0.181, 0.168, 0.059, 0.111, 2.873
