Omg these comments are annoying! Yes! We know you think we know this. But this specific part has now been proven with data, rather than just anecdote or assumption based on other studies.
"While climate models have predicted that this variability will increase with future warming, this study confirms that this pattern has already emerged over the past century.
By analyzing a wide range of observational data, the researchers found that rainfall variability has increased since the 1900s over 75% of the land areas studied, particularly in Europe, Australia, and eastern North America. The researchers found that daily rainfall variability has increased globally by 1.2% per decade."
