Ice ages are not that easy to define. It may sound intuitive that an ice age represents a frozen planet, but the truth is often more nuanced than that. 

NASA scientists have set out to transform the way the agency measures Earth's energy budget — a key gauge of climate health.

Researchers found that shaded corals recover more quickly from heat stress than corals with no shade.

Nearly one quarter of the land in the Northern Hemisphere, amounting to some 9 million square miles, is layered with permafrost — soil, sediment, and rocks that are frozen solid for years at a time.

Seasonally occurring fields of aufeis (icing) constitute an important resource for the water supply of the local population in the Upper Indus Basin. 

The Southern Ocean dominates the oceanic uptake of human-made CO2. But how much carbon dioxide can it actually absorb in the future?

Glaciers are a sensitive indicator of climate change – and one that can be easily observed.

The weather and fire forecasts for this coming summer are not looking particularly good, either.

California’s wildfire problem, fueled by a concurrence of climate change and a heightened risk of human-caused ignitions in once uninhabited areas, has been getting worse with each passing year of the 21st century.

For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses.
