Methane-releasing wetlands in Greenland are growing

An ongoing study has revealed significant shifts in Greenland's landscape since the 1980s, with melted ice giving way to vegetation, potentially exacerbating greenhouse gas emissions and sea level rise. Analysis shows a near-quadrupling of wetlands, contributing to methane emissions. The accelerated ice loss, driven by warmer temperatures, triggers further greening, as bare rock is colonised by vegetation. This feedback loop intensifies as melting ice releases sediment and forms wetlands. The findings underscore the complex interplay between ice loss, vegetation expansion, and coastal ecosystem changes, highlighting the urgent need for continued monitoring and adaptation efforts in Greenland's evolving environment.
