Researchers Sound Alarms Over Antarctic Ice Melt and Impending Coastal Risks
What’s happening in Antarctica? As global temperatures continue to edge upward, Antarctica’s ice sheets face unprecedented stress. Recent measurements and field studies indicate that the most vulnerable regions are melting at a pace not fully captured by earlier models. Scientists warn that conventional tools and models can miss complex ice dynamics, particularly in areas where…
