Climate Change Chronicles

Cameras set up in the Arctic’s Chukchi and Bering seas (one shown) record the amount of light that reaches water through the ice. More light means more algal blooms.

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

This is a little skate, a fish closely related to sharks and rays. As the oceans get more acidic, little skates may become better walkers.

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.”
