1 Intergovernmental Panel on Climate Change (IPCC) IPCC and Climate Change Özgür ZEYDAN (PhD) IPCC was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts. It reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change. It does not conduct any research nor does it monitor climate related data or parameters. Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) The IPCC is an intergovernmental body. It is open to all member countries of the United Nations (UN) and WMO. Currently 195 countries are members of the IPCC. Governments participate in the review process and the plenary Sessions, where main decisions about the IPCC work programme are taken and reports are accepted, adopted and approved. The IPCC is honored with the Nobel Peace Prize (Oslo, 10 December 2007) Note: Unless otherwise stated, all graphs an tables are token from these reports in this presentation. ( 1

2 Global Temperature Change Averaged over all land and ocean surfaces, temperatures warmed roughly 0.85 ºC from 1880 to 2012, according to the IPCC's Climate Change 2013: The Physical Science Basis Report was likely the warmest 30- year period of the last 1400 years. Reason of Climate Change: increasing amounts of greenhouse gases. Greenhouse Effect 2

Effects of Climate Change Increasing temperature Shrinking ice sheets Sea level rise Extreme weather events Biodiversity losses Water stress Forest fires Change in land use Floods Droughts Ocean acidification Sectorial effects (energy, health, food, tourism) Climate Change Scenarios 5

8 Climate Change Mitigation Climate mitigation is any action taken to permanently eliminate or reduce the long-term risk and hazards of climate change to human life, property. The International Panel on Climate Change (IPCC) defines mitigation as: "An anthropogenic intervention to reduce the sources or enhance the sinks of greenhouse gases." Climate Change Adaptation Climate adaptation refers to the ability of a system to adjust to climate change (including climate variability and extremes) to moderate potential damage, to take advantage of opportunities, or to cope with the consequences. The IPCC defines adaptation as the, "adjustment in natural or human systems to a new or changing environment. Adaptation to climate change refers to adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities." 8
