What is global climate change?

Global climate is the average climate over the entire planet. The reason scientists and many other folks are concerned is that Earth’s global climate is changing. The planet is warming up fast—faster than at any other time scientists know about from their studies of Earth’s history.

Is the climate of the whole Earth really changing?

What is climate?

“Climate” describes conditions over the long term and over an entire region.

Climate is the big picture. It is the big picture of temperatures, rainfall, wind and other conditions over a larger region and a longer time than weather. For example, the weather was rainy in Phoenix, Arizona, last week. But this city usually gets only about 7 inches of rain each year. So the climate for Arizona is dry. Much of Southern California also has a dry, desert climate. Brazil has a tropical climate, because it’s warm and rains there a lot.

What is weather?

TV weather reporters need all the information they can get in order to predict the weather for just a few days.

Weather is local and temporary.

On our own Earth, we cannot control weather by turning a thermostat up to make it warmer or down to make it cooler. The best we can do is try to predict the weather. Weather scientists, called meteorologists, try to foresee what’s going to happen next.

Is that big black cloud going to let loose over San Francisco, or wait until it gets to Sacramento? Will that new storm forming in the Atlantic Ocean turn into a hurricane? Conditions are just right for tornadoes. Will any form? And where might they touch the ground and cause trouble?

Weather happens at a particular time and place. Rain, snow, wind, hurricanes, tornadoes—these are all weather events.
