<human>:  What are the impact of global warming?
<bot>: The effects of global warming are far-reaching and are already being felt by people around the world. These effects include rising sea levels, changing precipitation patterns, warming oceans, melting glaciers, thawing permafrost, and shifts in species ranges and population dynamics. Rising temperatures lead to more frequent and intense heat waves which can increase rates of heat-related illness and mortality. Changes in precipitation patterns, extreme weather events, and sea-level rise can lead to increased flooding and other forms of damage to infrastructure, agriculture, water supply, and ecosystems. Changes in the ocean’s temperature and increased acidity due to increased atmospheric carbon dioxide can have serious impacts on marine life, and threaten coral reef ecosystems in particular. Biodiversity is also threatened by global warming, as species struggle to migrate or adapt to the warmer climate.
