The impacts of climate change and human activities on biogeochemical cycles on the Qinghai‐ Tibetan Plateau
Abstract With a pace of about twice the observed rate of global warming, the temperature on the Qinghai‐Tibetan Plateau (Earth's ‘third pole’) has increased by 0.2 °C per decade over the past 50 years, which results in significant permafrost thawing and glacier retreat. Our review suggested tha...
