Scientists shine light on 66-million-year-old meteorite wildfire mystery

Scientists have discovered that the meteorite that wiped out Earth's dinosaurs instantly ignited forest wildfires thousands of kilometers away from its impact zone. At the end of the Cretaceous Period 66 million years ago, a six-mile-wide meteorite struck the Yucatan peninsula in what is now...

Wildfires may have sparked ecosystem collapse during Earth’s worst mass extinction

Researchers from University College Cork (UCC) and the Swedish Museum of Natural History studied the end-Permian mass extinction (252 million years ago), which wiped out almost every species on Earth and collapsed entire ecosystems. The researchers discovered a significant increase in wildfire activity as...

Human-triggered California wildfires are more severe than natural blazes

Human-caused wildfires in California are more destructive than lightning-sparked flames, according to a study published recently in the journal Nature Communications by a team led by scientists from the University of California, Irvine. The findings could aid scientists in better understanding the intensity of...

Wildfire smoke accelerates glacier melt, affects mountain runoff

Wildfires are becoming more common, as global temperatures rise. University of Saskatchewan (USask) hydrology researchers found that exposure to wildfire smoke can cause glaciers to melt faster. It is affecting mountain runoff that provides major freshwater resources for life downstream. A team USask hydrology researchers...

Predicting particulate pollution levels from wildfires in a warming climate

Scientists have people living in the U.S. Northwest could see a tripling of particulate matter in the atmosphere by 2050 due to wildfires during the late summer months, via modeling that unless climate mitigation efforts are stepped up. The study was published in Proceedings...
