<human>:  How is climate change affecting our world?
<bot>: Climate change is having significant and wide-ranging impacts on our world, affecting both humans and the natural environment. As global temperatures rise, extreme weather events such as heat waves, floods, and droughts are becoming more common and intense. Rising sea levels and the melting of land-based ice sheets are leading to an increased risk of coastal flooding, as well as changes in ocean circulation, and increases in ocean temperature and acidity. These changes further impact global ecosystems, species, and habitats, and in turn, impact food production and human health.
