Changes in the Gulf Stream, a strong ocean current in the Atlantic, could serve as an early warning of the imminent collapse of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a massive system of ocean currents that acts as a…

Ancient hydrothermal carbon fuels microbes and crabs off Taiwan, study reveals
How is carbon metabolized and processed in different ecosystems? In a study published in the journal Communications Earth & Environment, researchers led by Joely Maak, the study’s first author and researcher in the Cluster of Excellence “The…

Most Saharan dust is generated by 'hidden thunderstorms' high above the desert
When Saharan dust reaches the UK and Europe, as a huge country-sized cloud did over the past few days, it can transform the sky. Tiny particles drifting in the atmosphere scatter blue light while allowing reds and oranges to reach us intact,…

Inland China experienced typhoon-related population decline 3,000 years ago, according to 'oracle bones,' AI and physics
Evidence suggests that China’s “cradle of civilization” experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient inland disasters were…

High-resolution ocean models better capture Atlantic-driven European heat waves
Europe is struggling more and more with extreme heat in the summer. While climate change is the main reason for this increase, what specific physical mechanisms cause a heat wave? One important driver of weather conditions in Europe is the North…

Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to the tropics, covering…

X-raying rocks reveals their carbon-storing capacity
To avoid the worst effects of climate change, many billions of metric tons of industrially generated carbon dioxide will have to be captured and stored away by the end of this century. One place to store such an enormous amount of greenhouse gas…

Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST research team…
