Disappearing sea ice could disrupt Arctic’s food web

Data from two U.S. agencies linked climate change with more rain in Eastern states — and flooding, such as here, in South Carolina.

Corals provide the base of a unique community of ocean creatures. But ocean acidification may make it difficult for corals to build their beautiful structures.

Space dust rains down on Earth all the time. Most of these specks are too small to see. But when one the size of a sand grain hits the atmosphere, it blazes with visible light, becoming a micrometeor, or “shooting star.”
