What’s the Beef About Methane?

by E. Davidson 26 May 202120 October 2021

Progress has been made to reduce methane emission intensity from livestock (the amount of methane per unit of protein), but where are the greatest opportunities to reduce this methane source further?

Coastal Flooding Enhances Methane Buildup in Forests

by Aaron Sidder 25 February 20212 November 2021

Increased seawater exposure from flooding and storms is altering how coastal forests cycle methane, leading to more greenhouse gas accumulation in tree stems and soil.
