Irreversible hotter and drier climate over inner East Asia

IMAGE: Tree-ring data from Siberian larch and other tree species show that heatwaves and soil drying of the Mongolian Plateau have accelerated in the past two decades. The region’s climate regime… view more  Credit: Ken Shono, Unsplash Mongolia’s semi-arid plateau may soon become as barren as parts of the American Southwest due to a “vicious cycle” […]

Irreversible hotter and drier climate over inner East Asia

Trees tell a heatwave and drought history of inner East Asia. The image shows a landscape in inner Mongolia, northern China, a Scots Pine (Pinus sylvestris L.) tree-ring sample, and a figure showing tree-ring-based heatwave and soil moisture reconstructions from Zhang et al. Science (2020). Credit: Peng Zhang, Hans Linderholm, Zhang et al., Science (2020) […]

Tree rings capture an abrupt irreversible shift in east Asia’s climate

The abrupt shift to hotter and drier conditions over inner East Asia is unprecedented and may herald an irreversible shift to a new climate regime for the region, according to a new study. The findings reveal a positive feedback loop fueled by declining soil moisture, which may have nudged the area’s climate over an important […]

Ice storms in Russia’s Far East prompts state of emergency

Freezing rain began pummelling Vladivostok overnight Thursday after a cyclone carrying hot air met an anticyclone carrying cold air Freak ice storms following an abnormal weather phenomenon has left 150,000 people without water and electricity in the far eastern Russian city of Vladivostok and prompted a state of emergency. The exceptional weather brought down cables and […]

Rising Seas and Agriculture Created Wetlands Along the U.S. East Coast

Most of the tidal marshes along the eastern coast of the United States formed within the past 6,000 years, according to new research published in Geophysical Research Letters. Braswell et al. used new and existing data to assess the age of coastal wetland areas. The new study found evidence for two bouts of […]
