Climate change is pretty straight forward. It is basically what it says in it's name, it explores how weather changes over longer periods of times from decades to millions of years. It can change in temperature, weather or even the distribution of extreme weather. Climate change can span from a range of only a specific town or to across the whole world. There are different studies of climate change from meteorologists who study the weather and present them in forecasts like seen on television or climatologists that research the weather conditions over a certain amount of time.
