A new study describes a period of rapid global climate change in an ice-capped world much like the present — but 304 million years ago. 

Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research published this month.

To help researchers model climate effects, the Earth Surface Mineral Dust Source Investigation mission will measure the composition of minerals that become airborne dust.

While the ozone loss was not a surprise, the simulations indicated the potential magnitude of the destruction

A forest’s ability to regenerate after devastating wildfires, droughts or other disturbances depends largely on seed production.

Millions of monarch butterflies migrate each fall to a specific cluster of mountain peaks in central Mexico.

When faced with conditions that are too dry, salty, or cold, most plants try to conserve resources. 

During the last ice age, glaciers covered vast portions of North America.

Seagrass beds are un­derwater oases. Now researchers have discovered vast amounts of sugars underneath seagrass meadows. 

Protected areas — such as nature reserves, national parks, and wilderness areas — are essential to conserving biodiversity.
