How do alpine plants react to warmer climatic conditions? Due to their longevity, the plants may survive longer than expected in their habitats, but produce offspring that are increasingly maladapted. Population size may decrease faster than the contraction of the species range, as UZH researchers show using computer models. Scientists who wish to track the precise extinction risk of plant species must not only measure their dispersal, but also the densities of the local populations.
A commitment to reducing global emissions of short-lived climate pollutants (SLCPs) such as methane and black carbon could slow global warming while boosting public health and agricultural yields, aligning the Paris Climate Agreement with global sustainable development goals, a new analysis by an international research panel shows.
Methane and black carbon – or soot – are the second and third most powerful climate-warming agents after carbon dioxide. They also contribute to air pollution that harms the health of billions of people worldwide and reduces agricultural yields.
A recent study, affiliated with UNIST has engineered a self-sustaining sensor platform to continuously monitor the surrounding environment without having an external power source.
Daydreams of the tropical paradise of Hawai?i rarely include snow in the imagery, but nearly every year, a beautiful white blanket covers the highest peaks in the state for at least a few days. However, systematic observations of snowfall and the snow cover dimensions on Mauna Kea and Mauna Loa are practically nonexistent. A group of climate modelers led by Chunxi Zhang from the International Pacific Research Center at the University of Hawai?i at M?noa used satellite images to quantify recent snow cover distributions patterns. They developed a regional climate model to simulate the present-day snowfalls and then to project future Hawaiian snowfalls. Their results indicate that the two volcano summits are typically snow-covered at least 20 days each winter, on average, but that the snow cover will nearly disappear by the end of the century.
Eating insects instead of beef could help tackle climate change by reducing emissions linked to livestock production, research suggests.
Bangalore (officially called Bangaluru) has become the enduring symbol of the economic transformation that makes India the envy of much of the developing and developed worlds. Its population and economy accelerated as just about every global information technology has set up operations in this city of 8.4 million people.
