Early spring rain boosts methane from thawing permafrost by 30 percent

As permafrost thaws, wetlands form, from which methane is released into the atmosphere due to microbial and plant processes. Methane is a powerful greenhouse gas with atmospheric warming abilities that can be up to 32 times stronger than that of carbon dioxide.

A new study led by Dr. Rebecca Neumann, an associate professor in the UW Department of Civil & Environmental Engineering, was recently published in Geophysical Research Letters examining the impact that spring rainfall has on permafrost thaw and wetland methane emissions.
