This picture is from the movie The Day After Tomorrow. While this picture depicts some impossible abrupt climate changes that occur within a few of weeks. However unrealistic this movie/picture is, research suggests that th abrupt climate changes we experience now are only going to increase in the future.

As this picture shows, " Earth's climate is anything but stable, with dramatic swings in cooling and warming over the past 1 million years (top) and past 140,000 years (bottom)"

"Climate change refers to a change in the average temperature, precipitation, winds, and other aspects of the climate system, in contrast to weather, which describes the constantly changing atmospheric circulation" (including storms such as the hurricane shown here in this picture) National Climatic Data Center

These climate changes usually occur over a vast amount of time, such as centuries, or maybe even longer. However, sometimes these climate changes can occur very rapidly-these are referred to as "abrupt climate changes"
