Geologists are today anticipating a rise in ocean levels of between 80 and 180 centimetres by 2100. But to fine-tune this prediction and upgrade the models underpinning it, we need to know about the recent past in greater detail – on a scale of a few thousand years instead of the millions of years that geologists usually work with. This tour de force was achieved by an international team of researchers that included the University of Geneva (UNIGE). The scientists succeeded in reconstructing the sea-level curve over the last 6,000 years in French Polynesia with unmatched accuracy: to within one centimetre. The research, which is based on analysing coral microatolls, is published in Nature Communications.

Over the past decades, Beijing, the capital city of China, has encountered increasingly frequent persistent haze events (PHEs). Severe PHEs not only lead to a sharp decrease in visibility, causing traffic hazards and disruptions, and, hence, affecting economic activities, but also induce serious health problems such as respiratory illnesses and heart disease. While the increased pollutant emissions serve as the most important reason, changes in regional atmospheric circulation associated with large-scale climate warming are found to play a role as well.

Millions of Chinese farmers have cut fertilizer use, reduced greenhouse gas emissions, and increased crop yields after adopting new region-specific management practices, according to a 10-year study published recently in the journal Nature. 

After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.

NASA got an inside look at the heavy rainfall within developing Tropical cyclone Eliakim. The new tropical cyclone that may affect Madagascar in a few days has been generating an impressive rate of rain.
