5. What is Climate
Change?

6. Climate change is a change in the statistical
distribution of weather patterns when that
change lasts for an extended period of time (i.e.,
decades to millions of years). Climate change
may refer to a change in average weather
conditions, or in the time variation of weather
around longer-term average conditions (i.e.,
more or fewer extreme weather events). Climate
change is caused by factors such as biotic
processes, variations in solar radiation received
by Earth, plate tectonics, and volcanic eruptions.
Certain human activities have also been
identified as significant causes of recent climate
change, often referred to as "global warming"
