So the bad news is that impacts of_extreme_droughts worsened dramatically over time, but the good news is that these systems were not progressively impaired by_moderate_droughts. And, for us, it's good news that we have published these findings! Stay tuned; many more DN manuscripts are in progress.

...while the effects of droughts that were extreme (i.e., 1 in 100 year events) compounded over time, perennial grasslands and shrublands were more resilient to less extreme droughts. That is, drought-related reductions in plant growth did not magnify over more years of moderate drought. (2/3)
Two panel graph showing the productivity response of ecosystems to moderate drought remained constant from 1-4 years of drought, while the productivity progressively decreased from the first to the fourth year of drought in systems consistently exposed to extreme drought.
