It is hoped the findings, published recently in the Journal of Applied Volcanology, will help increase our understanding of volcanic hazards and the subsequent threat to life.

Over the past decade, increasing temperatures across much of Africa and decreasing rainfall across East Africa have come to represent an alarming climate trend. Chief among concerns is the impact such conditions have on human health.

As China struggles to find ways to remedy the noxious haze that lingers over Beijing and other cities in the winter, researchers from Georgia Institute of Technology have cast serious doubt on one proposed cause: high levels of ammonia in the air.

The wintertime air pollution has gained attention in the scientific community in recent years, prompting some scientists to propose that ammonia, emitted into the air from agricultural activities and automobiles, could be a precursor that strongly promotes the formation of the haze.

Georgia Tech researchers countered that theory in a study published September 21 in the journal Scientific Reports. The study was sponsored by the National Science Foundation.

Nearly half of the organic carbon stored in soil around the world is contained in Arctic permafrost, which has experienced rapid melting, and that organic material could be converted to greenhouse gases that would exacerbate global warming.

The 2017 hurricane season has highlighted the critical need to communicate a storm’s impact path and intensity accurately, but new research from the University of Utah shows significant misunderstandings of the two most commonly used storm forecast visualization methods.
