Accelerated climate warming is drastically diminishing glaciers, permafrost, and perennial snow cover in mountain regions across the world. With increased radiative forcing and decreased snowfall, alpine climates are becoming warmer and wetter, elongating ice-and snow-free growing seasons. Receding glaciers and permafrost thaw are likely to deliver increasing amounts of meltwater containing solutes, sediments, contaminants, and nutrients to connected lake and stream ecosystems. Connectivity of lakes and streams will reorganize as a function of meltwater export from continued glacier decline. Downstream aquatic ecosystems may experience high turbidity, shifting nutrient limitation patterns, and changes in thermal regimes. Ecological impacts will be variable among systems, but can include changes in ecological communities and biodiversity, invasive species intrusion and altered species distributions, changes in trophic structure, and increased primary productivity rates. Understanding these complex drivers and changes requires broad and interdisciplinary knowledge that spans across climate, cryosphere, and aquatic habitats. To meet this challenge, 20 Chinese and 19 American scientists met for a cooperation workshop from August 21–26, 2017, at Qinghai Lake (青海湖), Qinghai Province, China. Qinghai Lake, located within the glaciated landscape of the Tibetan Plateau, is the largest inland lake in China, well-known for its saline waters and bar-headed goose nesting colonies. This location was an ideal setting to combine climatic, cryospheric, and ecological expertise. Attending scientists from diverse disciplines
