Warming trends drive heatwaves while shifting variability dictates heavy rainfall
In short: Researchers using large-ensemble climate simulations found that different mechanisms drive changes in extreme weather events. While the increasing frequency of monthly high-temperature extremes is primarily governed by a warming mean climate, future shifts in heavy precipitation events depend significantly on changes in climate variability.
This distinction matters because our understanding of global averages is generally more robust than our understanding of climate variability. The study used a probability ratio concept to separate these two influences across various regions and models.
The research highlights that temperature projections are likely more reliable than precipitation ones. However, the study was limited by its reliance on climate simulations rather than direct observational data.
Why it matters: Knowing the difference between average shifts and variability is key to predicting which types of extreme weather will become more frequent.
