"Rapid Vegetation Growth in Greenland Raises Global Concerns"

A study shows that Greenland has lost a significant amount of ice in the past three decades, leading to a doubling of vegetation and quadrupling of wetlands. This ice loss is driven by warmer air temperatures, which in turn causes permafrost melt, releasing carbon dioxide and methane. The resulting feedback loop leads to further ice loss and "greening" of Greenland, contributing to more global warming and sea level rise. These changes are particularly problematic for indigenous populations and pose significant challenges for the future.
