6.   The term used to explain the gradual warming of the planet from human activity is called global warming.  The most dangerous activity is the burning of fossil fuels which send tons of emissions into the atmosphere. These emissions act like a blanket warming the earth.  The gradual warming is causing changes to the climate. The changes in climate are causing our weather to be more extreme—droughts, floods, stronger storms, etc.  The actions we take every day influence the number of emissions sent into our atmosphere.  One person’s efforts, when multiplied, can make a big difference. Of course, political leadership and social efforts are also needed to reduce these emissions.
