The Panamanian golden frog (Atelopus zeteki) is a member of the harlequin frogs (Genus: Atelopus). Scientists estimate that about 67 species of harlequin frogs have gone extinct due to fungus outbreaks. Evidence links these outbreaks with climate change.

Human activities, including the use of fossil fuels in automobiles, are responsible for an increase in carbon dioxide in the atmosphere over the last 250 years.

NSF-funded 'sea' researchers study the ocean's composition, currents, ecosystems and atmospheric interactions. The seafloor is an important source of information about Earth's climatic past; layers of sediment contain a wealth of information about the sea and atmospheric conditions that were present when the sediment layers were first deposited.

NSF-funded 'ice' researchers study Earth's cryosphere, which includes both polar regions as well as high-altitude glaciers and snow cover on Earth's landmasses. Ice and snow play a critical role in Earth's climate system.

NSF-funded 'sky' research includes studies of physical and chemical atmospheric phenomena. Computational models of atmospheric processes allow researchers to predict what the climate of the future might be like.

NSF-funded 'land' research includes studies on land use and how changing land use affects the global carbon cycle.
