Human: I've been hearing a lot of news lately about global warming. What is it all about? Assistant: 
Global warming is the increase in the average temperature of Earth's atmosphere and oceans due to the release of greenhouse gases into the atmosphere. This causes an increase in the average temperature of the planet, which can have devastating effects on our environment and ecosystems. The most significant effect of global warming is rising sea levels, which can lead to coastal flooding and destruction of habitats. Other impacts include changes in weather patterns, more extreme weather events such as hurricanes and tornadoes, and changes in precipitation and drought.
