A new study by scientists and graduates at the University of Plymouth has investigated one aspect of how the future environmental conditions created by the changing global climate might affect earliest development within Christmas Island’s red crab population
Bacteria and other single-celled microorganisms in the seas around Antarctica are strongly influenced by water temperature and the amount of sea ice. This is shown by coordinated measurements taken off the coast of the west Antarctic Peninsula. "Even at two locations that are only 400 km apart on the peninsula – a very short distance on oceanographic scales – we found striking differences in the composition and relative abundances of microorganisms. These differences seem to be related to the differences in local climate", says NIOZ computational microbiologist Dr. Julia Engelmann. The results of this study by an international team of scientists led by NIOZ, are published in the journal Environmental Microbiome.
As climate change and population growth increase pressure on global food production, regional-scale crop growth and associated process (CROP-AP) models have become essential tools for understanding and predicting agricultural productivity. A new review, published in Science China Earth Sciences, categorizes these models into four types—statistical models, crop growth models, hydrology-crop coupling models, and ecosystem models. The study explores their main functions from five aspects: crop yield prediction, crop water consumption, agricultural non-point source pollution, greenhouse gas emissions, and climate change impact and responses, and identifies key future research directions, including model validation and calibration, the ability to simulate the coupling of crop physiology and human activities, enhancing model scalability, multi-model ensembles, data and code sharing, and the integration of artificial intelligence.
South Korea and Germany aim to transition to a climate neutral energy system. To do so, both countries must tackle scientific and technological challenges. At a joint symposium of the Korean Academy of Science and Technology (KAST) and the German National Academy of Sciences Leopoldina, experts discussed key topics relating to the energy transition. The joint paper summarising the findings, published today and titled “Navigating the Energy Transition in Korea and Germany”, examines scientific and technological challenges in the areas of solar technologies, hydrogen, batteries, grid management, and future energy sources, and includes recommendations for the energy transition in South Korea and Germany.
The Permian-Triassic mass extinction was caused by volcanic eruptions in what is now the Siberian Traps, releasing 100,000 billion metric tons of carbon dioxide into the atmosphere over a million years and killing off most animals, except for a few lineages — including the animals that would evolve, in the Late Triassic, into the earliest dinosaurs. Recovery took several million years. Now scientists have used modelling and plant fossils to follow the biosphere’s transition to 10 degrees of warming which eradicated tundra habitats and made polar regions temperate, helping us understand the consequences of this extreme climate change in deep time — and possibly even the consequences of our own CO2 emissions.
MIT aerospace engineers found that greenhouse gas emissions are changing the environment of near-Earth space in ways that, over time, will reduce the number of satellites that can safely operate there.
