Impacts: Effects on natural and human systems. In this report, the term impacts is used primarily to refer to the effects on natural
and human systems of extreme weather and climate events and of climate change. Impacts generally refer to effects on lives,
livelihoods, health, ecosystems, economies, societies, cultures, services, and infrastructure due to the interaction of climate changes or
hazardous climate events occurring within a specific time period and the vulnerability of an exposed society or system. Impacts are
also referred to as consequences and outcomes. The impacts of climate change on geophysical systems, including floods, droughts,
and sea level rise, are a subset of impacts called physical impacts.
