The end-Permian extinction (EPE) was the greatest biotic crisis in Earth's history, eliminating more than 90% of species in the oceans and more than 70% of species on land.
When ocean waves break, microscopic particles break free into the air. For beachgoers, aerosolized sea salts contribute to the tousled "beach hair" look. But other compounds found in seawater, including perfluoroalkyl substances ...
The most severe mass extinction event in the past 540 million years eliminated more than 90 percent of Earth's marine species and 75 percent of terrestrial species. Although scientists had previously hypothesized that the ...
It's not just how hot the fires burn—it's also where they burn that matters. During the recent extreme fire season in Australia, which began in 2019 and burned into 2020, millions of tons of smoke particles were released ...
A recent analysis of the latest generation of climate models—known as a CMIP6—provides a cautionary tale on interpreting climate simulations as scientists develop more sensitive and sophisticated projections of how the ...
For a long time, the production of ceramic coatings has only been possible by means of sintering techniques conducted at more than 1,000 degrees Celsius. However, a novel spraying method, Powder Aerosol Deposition (PAD), ...
Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated ...
Rainfall from the Asian summer monsoon has been decreasing over the past 80 years, a decline unprecedented in the last 448 years, according to a new study.
The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership ...
Simply reducing greenhouse gas emissions probably is not going to be sufficient for the planet to escape catastrophic damage from climate change, scientists say.
