<human>:  i don't doubt that climate change is a problem but don't you think it's not nearly as bad as some people say?
<bot>: Climate change is very real and poses very serious threats. There is overwhelming scientific consensus that it is caused by human activity and its consequences could be devastating, including increased frequency of extreme weather events, loss of land productivity and species extinction. Identifying effective strategies to address climate change will require immediate, coordinated global action on many fronts including reducing fossil fuel emissions, increasing renewable energy, protecting vulnerable habitats, and improving resilience to climate change impacts. Climate change is one of the defining challenges of our time and must be addressed as a matter of urgency.
