Which geological consequence accelerates when permafrost thawing increases Arctic coastline sea cliff erosion?

💡 Explanation

When permafrost thaws, organic matter decomposition accelerates because it becomes available for microbial activity in newly liquid water, resulting in the production and release of greenhouse gases like methane. Therefore increased methane release rates result, rather than sediment decrease, albedo change, or weathering, each involving distinct mechanisms.
