Summer precipitation in the middle and lower reaches of the Yangtze River generally shows synchronous variability and is thus extensively studied as a unified climatic region. However, out‐of‐phase variations occur between the middle and lower reaches in some years. This study investigates the mechanisms of the positive middle Yangtze River precipitation (MYRP)–negative lower Yangtze River precipitation (LYRP) pattern from the...

Within the context of global climate change, coastal blue carbon ecosystems (e.g., mangroves, salt marshes, seagrass meadows, and macroalgae) have emerged as critical natural carbon sinks. Yet, persistent methodological inconsistencies and geographic biases hinder their reliable incorporation into blue carbon management and climate prediction. Here, we synthesize current understanding of source-sink characteristics, drivers, a...
