Although more Arctic sea ice survived this year [2014] than in the record-shattering melt of 2012, in 2014 the ice was nevertheless at its 6th-lowest level in thousands of years. About 70% of the sea ice in the Arctic has disappeared over the past three decades, mainly due to human-caused global warming. This rapid decline is well outside “the normal range” of Arctic sea ice extent and volume.

The total heat content of the Earth has been rising at a relatively costant pace since about 1965. Most of the heat (about 80%) has been absorbed by the oceans.

The percentages were calculated from Figure 5.4 from Section 5.2.2.3 of the IPCC 4th Assessment Report (h/t to Humanity Rules for the heads up). The IPCC graph shows changes in energy content for two different periods: 1961 to 2003 and 1993 to 2003. The ocean heat figure of 93.4% is almost certainly an underestimate as it only includes ocean heat down to 700 metres (Levitus 2005).

Where is global warming going
Only about 2.3% of the excess energy is used to warm the atmosphere, while about 1.3% is used to melt glaciers and about 0.8% is used to melt Arctic sea ice.
