>It's definitely climate change because something bad happened. Not classical phenomena about wind currents drying out vegetation.

>[T]he extent to which this trend is due to weather pattern changes dominated by natural variability versus anthropogenic warming has been unclear... Our results show that for the period 1979 to 2020, variation in the atmospheric circulation explains, on average, only 32% of the observed VPD [vapor pressure deficit] trend of 0.48 ± 0.25 hPa/decade (95% CI) over the WUS during the warm season (May to September). The remaining 68% of the upward VPD trend is likely due to anthropogenic warming.[0]
