Abstract: The IPCC WGII AR5 assessed the climate change impacts on human health, human security, and livelihood & poverty. It concludes that climate change has negatively affected human health and security; climate change, climate variability and climate extremes have added extra burden to the poor in the urban and rural areas, increasing climate-related risks. Throughout the 21st century, climate change is projected to further exacerbate health problems that already exist, increase human migration, multiply conflict drivers, cause damages to the key infrastructures and services in many countries, and challenge the territorial integrity of the small island states and countries that own long coastal lines; climate change is projected to slow down economic growth, erode food security, prolong existing and create new poverty traps in urban and rural hotspots, and make poverty reduction more difficult.

Key words: climate change, impact and adaptation, human health, human security, livelihood and poverty
