<human>:  How does global warming impact the climate?
<bot>: Global warming is one of the most pressing environmental issues today, and it affects the climate in a variety of ways. Rising temperatures cause glaciers and snow to melt, sea levels to rise, and can lead to increased frequency and intensity of extreme weather events such as hurricanes and floods. There is also potential for more frequent and longer droughts, heat waves and wildfires. These changes impact the environment, land use, infrastructure and communities, and have implications for human health and safety, wildlife, and the global economy.
