Weather, climate and hydrometeorology forecasts require accurate surface-atmosphere coupled modeling, but arbitrary reference heights have been used in computing surface turbulent fluxes. A team of atmospheric scientists have found optimal coupling heights for improved surface-atmosphere modeling.
Dating key tectonic events in Japan's geological history has long been often challenging due to poor microfossil preservation from intense heat due to metamorphism. Researchers tackled this by using Re–Os isotope geochronology on Besshi-type volcanogenic massive sulfide deposits (Makimine and Shimokawa deposits) associated with sediment-covered mid-ocean ridges. Their findings revealed the timing of ridge subduction—when one tectonic plate was forced beneath another—a process that shaped Japan's landscape and provided new insights into its geological evolution.
An interdisciplinary team of researchers from Nanyang Technological University, Singapore (NTU Singapore), and Delft University of Technology (TU Delft), The Netherlands, has projected that if the rate of global CO2 emissions continues to increase and reaches a high emission scenario, sea levels would as a result very likely rise between 0.5 and 1.9 metres by 2100. The high end of this projection’s range is 90 centimetres higher than the latest United Nations’ global projection of 0.6 to 1.0 metres.
