<human>:  I want to know more information about climate change.
<bot>: Climate change is the long-term alteration of global climate patterns caused by human activities. It has caused temperatures to increase, sea levels to rise, extreme weather events such as hurricanes and floods to become more frequent and more intense, and sea ice and glaciers to melt. The effects of climate change can vary greatly depending on location, but some of the most common includes increased droughts and heat waves, changes in precipitation patterns, disruption of ecosystems, and an increase in extreme weather events. A rise in global temperatures is expected to have wide-ranging and mostly negative impacts on communities, economies, and wildlife.
