This is a common finding when studying drought in the recent instrumental record and in future projections: much more change in metrics that include the impacts of warming (on vapor-pressure deficit and potential evapotranspiration) when compared to changes in precipitation alone.

Figure from a Hydrology and Earth System Sciences article about projections of drought in Australia, showing much larger changes for a drought index that includes potential evapotranspiration (SPEI) than for one that only includes precipitation (SPI).

📣 Summer low flows decreased in Germany in the last 5 decades and increases in evapotranspiration played a role in that, esp in less humid areas.

Consistency is key in science. I've long defended the role of global warming in drought severity. Still, science requires an open mind—opinions may evolve with new data, methods, or debate. That’s not weakness; it’s how science grows.
