Drop in Greenhouse Gas Caused Global Cooling 34 Million Years Ago, Study Finds

The findings confirm that carbon dioxide plays a significant role in any climate change.

Smooth pearls in the shape of orbs and ovals are usually created by bivalves, like mussels, in pearl farms. As with all gems, the less blemishes they have, the more valuable they are. (Chip Clark, Smithsonian)

The True Story Behind How Pearls Are Made

Learn about how mollusks create these shiny gems and how that biological process could change as Earth’s waters warm

The world’s smallest moth, the pygmy sorrel moth, has a wingspan as short as 2.65 millimeters. It belongs to a group called the leaf miner moths, which could become problematic pests for more farmers as global temperatures rise. (Patrick Clement, CC BY 2.0)
