🧊 Arctic sea ice slowdown? Ice hasn’t shrunk much since 2005 — but it’s still half the 1980s size. This pause is natural variation, not recovery. The Arctic is warming 4x faster than the global avg. 📉 Loss could soon accelerate fast. 🔗 Read Dr.

Why Spring Is Critical for Harp Seal Pups ❄️ Harp seal pups are weaned just 10-12 days after birth. By spring, they must adapt fast as sea ice melts. As the Arctic warms, ice breaks up earlier, threatening pup survival and disrupting the marine food web. 🔗 Learn more:
