Question

How can global warming cause cold weather?

Answer 1

Climate change refers to changes in weather patterns and climate over long periods of time, hundreds of years. Usually, when we're referring to climate, we're talking about at least thirty years. Weather is what we experience over a shorter period of time. To learn more, click here. Thus, cold weather does not necessarily say anything about climate. If you look at weather patterns over decades, then you should be able to say something about the climate.

For example, in the image below, we can see that there are some dips in average temperature. If we look at the larger picture, we see that there is clearly a general trend of warming.
