Asian Pollution Affects World’s Weather

April 18, 2014 12:02 pm | by Pacific Northwest National Laboratory | News | Comments

The first study that combines different scales into one model to simulate the effects of Asian pollution on the Pacific storm track has shown that the pollution can influence weather over much of the world. These results show that using multiple scales in one model greatly improves the accuracy of climate simulations.

System Disruption May Release Huge Amounts of Methane

April 18, 2014 7:00 am | by European Association of Geochemistry | News | Comments

Researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atmosphere. However, there are worries that if this system is disrupted it may release large amounts of methane back into the atmosphere.
