Persistent trends and geographic traits of heat waves in a changing climate
By adopting a heatwave (HW) definition with a ∼4-year recurrence frequency at world hot spots, we first examined the 1940–2022 HW climatology and trends in lifespan...- publication PDF

Insights into mechanisms governing forest carbon response to nitrogen...
In many forest ecosystems, nitrogen (N) deposition enhances plant uptake of carbon dioxide, thus reducing climate warming from fossil fuel emissions. Therefore, accurately...- publication PDF
