A study led by researchers from Lawrence Berkeley National Laboratory reveals a nine percent increase in methane emissions from Arctic-Boreal wetlands over the past 20 years. Published in Nature Climate Change, the study employed advanced monitoring techniques to analyze data from various sources. The Boreal and Arctic ecosystems, experiencing a warming rate four times faster than the global average, are vulnerable to climate change.
Methane, with a potent warming effect, is released as temperatures rise, triggering microbial activity in saturated soils. The research team utilized eddy covariance towers and gas chamber measurements to analyze over 307 years of methane emissions data, finding an average annual emission of 20 teragrams, with a 9% increase since 2002.
Identifying temperature and plant productivity as key factors influencing emissions, the study emphasizes the need for precise methane quantification in high-latitude regions. Understanding and managing these emissions are crucial for effective climate change mitigation.
