40% of Earth's coral reefs are in critical condition or already degraded beyond recovery. Find out why these amazing marine animals are so important to our planet.
The cryosphere is highly variable on time scales ranging from days to hundreds of thousands of years. Changes in snow and ice cover influence environmental conditions like air temperature, sea level, ocean currents, and storm patterns. Find out what we can learn from the cryosphere about past, present, and future changes in climate and how those changes will impact life on Earth.
What happens when a region gets less than its "normal" amount of rain and snow in a year? What if the new, drier conditions last for a decade?
Find out how marine fisheries have been used by humans over time, and about the efforts to keep this resource sustainable.
