The Fourth Assessment Report of the IPCC WGII (Climate Change Impacts, Adaptation, and Vulnerability) does not have much to say about energy or reducing greenhouse gas emissions. It does contain this warning, however,
Even the most stringent mitigation efforts cannot avoid further impacts of climate change in the next few decades, which makes adaptation essential, particularly in addressing near-term impacts. Unmitigated climate change would, in the long term, be likely to exceed the capacity of natural, managed and human systems to adapt.
