 ===IPCC summary=== 

 I've prepared a draft of how I think the IPCC reports should be summarized: 

 : The IPCC has produced a number of reports on climate change. The lead summarizes some of the key findings from the IPCC's Fourth Assessment report (AR4), published in 2007. In addition to these findings, the IPCC has concluded that climate change will lead to an increase in the frequency and severity of some extreme weather events, such as heat waves and wildfires . Other effects include sea level rise and ocean acidification . 

 : AR4 contains an assessment of policy responses to climate change. These are divided into two main categories: policies to adapt to the effects of climate change, and policies to mitigate the effects climate change. Adaptation are efforts to reduce the negative effects of climate change, e.g., through building levees in response to rising sea levels. Mitigation are actions to reduce net greenhouse gas emissions, e.g., by increasing use of renewable energy sources and reducing deforestation. AR4 concludes  
 : - "Some planned adaptation (of human activities) is occurring now; more extensive adaptation is required to reduce vulnerability to climate change." 
 : - "Unmitigated climate change would, in the long term, be likely to exceed the capacity of natural, managed and human systems to adapt" 
 : - "Many [climate change] impacts can be reduced, delayed or avoided by mitigation."
