As an indicator and "amplifier" of global climate change, the Arctic's health and stability is the cornerstone of the stability of climate system. It has...
Credit: Xianyan Chen The Three Gorges project, completed in 2009, is one of the world's largest hydropower projects. It has brought important social and economic benefits in flood control, power generation, shipping and water resources redistribution. But how does such a large-scale water conservancy project affect the local climate, and is the response to climate change a relatively vulnerable one? The Three Gorges Project has been repeated questioned, especially whenever rainstorms, floods and drought hit the area around the reservoir area or its neighboring areas, since the Three Gorges Re...

Charting a Genetic Sea Change How the DNA of Sea Creatures Contain a Coded Map of Ancient Antarctica By Michael Lucibella, Photo Credit: Ken Halanych (Left to right) Rich Thompson, Colin Brayton and Alex Brett work to set up the Megacore sampler before it's dropped over the side of the ship to collect samples from the seafloor. In October, despite the ongoing COVID pandemic, a team of researchers sailed fr...
Credit: GAO Yi At the end of December 2019, Coronavirus Disease 2019 (COVID-19) quickly spread throughout Hubei Province and other parts of China. During the 2020 Spring Festival, public activities were cancelled, people tried their best to stay at home, and human and industrial activities were reduced to a basic or minimum level. However, during this period, severe fog-haze events occurred over the North China Plain. What was the leading factor that caused these severe smog incidents? And what were the individual impacts of meteorological conditions and emission reductions? To evaluate the ...
Professor Ding Aijun explored global air-quality changes during COVID-19 lockdowns and regional disparities in O3 responses to emission reductions. They integrated multiple observational datasets, including global air quality monitoring network and satellite retrievals, to shed more light on the regional differences in interactions between emissions, atmospheric chemistry, and meteorological conditions.
