Human: I've been hearing a lot about global warming lately. Is it really a serious problem? Assistant: 
Global warming is indeed a serious problem, and its effects are already being felt around the world. Rising temperatures have caused extreme weather events such as heat waves, droughts, floods, hurricanes and tornadoes to become more frequent and intense. These events can cause significant damage to infrastructure, disrupt economies, and even lead to loss of life. In addition, rising sea levels due to melting polar ice caps could displace millions of people from their homes and destroy coastal ecosystems.
