The terms “climate change” and “global warming” are often used interchangeably. Many people prefer the term “climate change” because it emphasizes that there are other changes besides increasing average temperature.
Technically, “global warming” refers to an increase in the average temperature of the troposphere (the lowest part of the earth’s atmosphere). It’s usually used to refer to the warming caused by greenhouse gases emitted by human activities.
“Climate change” refers to any extended change in climate (including temperature, precipitation, wind, and other meteorological elements). It’s usually used to refer to the changes in climate that result from global warming.
A rapidly changing climate poses serious threats to people and to the natural world, but there are simple tools we can each use to become part of the solution. By measuring your footprint, doing what you can to reduce emissions, and helping build renewable energy projects in communities across the US, you can make great strides toward eliminating your personal impact on the climate and helping ensure a bright future.
