Global warming is often said to increase storms and to make storms more severe. The question of whether global warming was responsible for a notable storm is often asked in conjunction with a severe storm event, such as Hurricane Harvey. Or, the inquiry might be, did global warming make the storm more intense than it would have been otherwise? While it is impossible to assert blame for a certain storm, the understanding of how global warming impacts our weather is something we can have, and global warming is a key player in storm frequency and intensity.
There are two things we must consider in the impact of global warming on weather. First, we must look at the impact of global warming on local weather. Second, we must consider the impact of global warming on the Earth’s circulation as a whole, which has a great influence on the Earth’s weather.
