<human>: I've been hearing a lot of talk about global warming lately. What are the main effects of climate change?
<bot>: The primary effect of climate change is rising temperatures, which can lead to changes in weather patterns and sea levels, as well as more extreme weather events like droughts, floods, hurricanes, and tornadoes. Other impacts include decreased air quality due to increased levels of greenhouse gases, shifts in ecosystems, and an increase in the frequency of natural disasters.
