In a groundbreaking study published in the journal Nature Cities, a team of Earth scientists, environmental engineers, and geomaticists have uncovered a surprising trend in urban development. Contrary to historical patterns of outward expansion, cities around the world are now growing more vertically than horizontally. This shift in urban growth has significant implications for city

The recent study led by researchers at McGill University sheds light on the potential impact of Antarctic ice melt on rising sea levels. It emphasizes the crucial role that carbon emissions play in influencing the rate of ice loss from the continent. The findings suggest that if carbon emissions are not reduced swiftly in the
Predicting tipping points for critical Earth system components such as the Atlantic Meridional Overturning Circulation (AMOC), polar ice sheets, and tropical rainforests is a daunting task due to significant uncertainties. A recent study published in Science Advances highlights the challenges in accurately forecasting when these tipping events might occur in response to human-caused global warming.
Studying ancient ocean temperatures is crucial for understanding past climate conditions and predicting future climate trends. One common method used to reconstruct these temperatures is by analyzing the ratio of different oxygen isotopes in calcium carbonate remains of fossils. However, this approach is not without its challenges, as biological processes known as “vital effects” can
Interbasin water transfers play a crucial role in transporting water across vast geographical areas in the U.S. West. The recent research published in the journal Nature Water sheds light on the energy-related greenhouse gas emissions associated with these projects, with two key projects in Arizona and California contributing to a majority of the emissions. The
