Valencia floods: Warming climate is making once-rare weather more common and more destructive, says researcher
In the last few days, a seasonal weather system known in Spain as the "cold drop" or DANA (an acronym of "depresión aislada en niveles altos": isolated depression at high levels) has caused heavy rain and flooding across Spain's Mediterranean coast.....»»
Study finds 30% of regions worldwide achieve economic growth while reducing carbon emissions
More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research and the University of Potsdam found......»»
Bio-based fibers could pose greater threat to environment than conventional plastics
Bio-based materials may pose a greater health risk to some of the planet's most important species than the conventional plastics they are designed to replace, a new study has shown......»»
Missing a deadline has a bigger impact than you might think, according to study
Missing a deadline has more complex consequences than you might think. Researchers at the University of Toronto found that if you submit a piece of work late, people will think it's lower in quality than if you were to submit the exact same work on t.....»»
