“The NASA web page, one of many gov entities, has defined climate change,” as one of our readers, Russell, points out. “It is extremely broad and inclusive, and literally means any variation in weather data is climate change. See below:
Climate change, therefore, is a change in the typical or average weather of a region or city. This could be a change in a region’s average annual rainfall, for example. Or it could be a change in a city’s average temperature for a given month or season.
Climate change is also a change in Earth’s overall climate. This could be a change in Earth’s average temperature, for example. Or it could be a change in Earth’s typical precipitation patterns. The climate of a region or city is its weather averaged over many years. This is usually different for different seasons. For example, a region or city may tend to be warm and humid during summer. But it may tend to be cold and snowy during winter.
The climate of a city, region or the entire planet changes very slowly. These changes take place on the scale of tens, hundreds and thousands of years.
“By this definition climate change occurs daily. Saying any action fights climate change is utterly meaningless.”
