Anak Krakatau, which means Child of Krakatoa, has been active sporadically since it emerged from the sea at the beginning of the last century in the caldera formed after the 1883 eruption of Mount Krakatoa.
New research brings together recent advances in urban hydrology, boundary-layer meteorology, extreme precipitation and flood-risk research and proposes a new framework for understanding how cities and extreme rainfall interact ...
The area covered by the Antarctic ozone hole peaked at more than 27 million square kilometers (10.4 million square miles) in September, the second-largest area ever observed for this time of year.
New research from the University of California, Santa Cruz, in collaboration with other institutions, highlights the fragmented and staggered timing of warming increases across the planet, providing a nuanced perspective ...
As students return to school and cold and flu season begins, researchers are studying ways to improve indoor air quality and reduce the risk of airborne disease transmission.
Most kids learn in elementary school that the seasons are caused by Earth rotating on a tilted axis during its yearly orbit around the sun. The substantial tilt, about 23.5 degrees, is thought to be the result of an ancient ...
