... Critics of the leaked drafts have focused on what climate scientist Kevin Trenberth said is the «mistaken idea that warming has slowed... «A key will be whether there is a major succinct message out of this report,» said Trenberth, a climate scientist at the National Center for Atmospheric Research, also in Boulder, Colo. «The previous three have had signature messages,» Trenberth said.

This display of counter-trend warming and strong polar amplification are both signature effects of human - caused climate change.
Furthermore, the missing hotspot in the atmospheric warming pattern observed during the last warming period proves that (1) the IPCC climate theory is fundamentally broken, and (2) to the extent that their theory correctly predicts the warming signature of increased carbon dioxide, we know that carbon dioxide definitely did not cause the recent warming (see here for my full explanation of the missing hotspot).

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4
Given historical climate and physics, the only way that implicit endorsement means «implicitly endors [ing] that humans are a cause of warming» where «a» is something less than primary (that is, over half) is if there is some as - yet undiscovered sink absorbing human CO2 emissions and, simultaneously, an as - yet undiscovered source of CO2 that is releasing it into the atmosphere - and moreover, the CO2 from this mysterious source just happens to possess a carbon isotope signature that matches fossil fuel CO2 as a total coincidence.
