<human>:  I have a question about the Costs of climate change. When you say “costs”, what do you mean?
<bot>: I mean the costs of climate change. Climate change is a global problem that is caused by human activities, such as burning fossil fuels and deforestation. These activities release greenhouse gases into the atmosphere, which trap heat and cause the Earth’s temperature to rise. This rise in temperature has many negative effects, including rising sea levels, more extreme weather events, and changes in the climate system.
