Simply put, said Patrick Behrer, the world is getting hotter "and that heat imposes large costs on people." In particular, those who work outdoors or in factories lacking air conditioning or ventilation are most at risk for ...
Bioscience engineers at KU Leuven (Belgium) have developed a method to measure the snow depth in all mountain ranges in the Northern Hemisphere using satellites. This technique makes it possible to study areas that cannot ...
Spring has barely arrived, and bushfires are burning across Australia's eastern seaboard. More than 50 fires are currently burning in New South Wales, and some 15,000 hectares have burned in Queensland since late last week.
For the world's estimated 1.8 billion Muslims—roughly one-quarter of the world population—making a pilgrimage to Mecca is considered a religious duty that must be performed at least once in a lifetime, if health and finances ...
