As the ocean warms and land ice melts, ocean circulation — the movement of heat around the planet by currents — could be impacted. Research with NASA satellites and other data is currently underway to learn more.

NASA has selected a new mission to help humanity better understand Earth’s dynamic atmosphere – specifically, ice clouds that form at high altitudes throughout tropical and subtropical regions.

Climate change plays an increasing role in the global decline of biodiversity—the variety of life on Earth. Scientists use NASA data to track ecosystem changes and to develop tools for conserving life on land, in our ocean, and in freshwater ecosystems.

Researchers found that emissions of the powerful greenhouse gas dropped for several years near the nation’s second-largest metropolitan area.

From insect-borne diseases to seasonal allergies and “superbugs,” climate change is quite literally getting under our skin, affecting our health in often surprising ways.

Kelvin waves, a potential precursor of El Niño conditions in the ocean, are rolling across the equatorial Pacific toward the coast of South America.

The amount of CO₂ in the atmosphere is measured at Mauna Loa Observatory, Hawaii, and all around the world. NASA also measures CO₂ from space. Data from around the planet all shows the same upward trend.

Researchers created a toolkit for determining the clarity and surface temperature of coastal waters. The data is freely accessible and can help assess reefs around the world.

A new NASA Climate feature series examines some of the lesser-known, and often surprising, ways global climate change is affecting our world. First up: transportation.

From space, air, and on the ground, NASA studies Earth and the ways it is changing. These observations help us better understand – and prepare for – the effects of human-caused global warming. Today, the agency released its 2023 climate strategy.

NASA’s Images of Change gallery has added a new feature: "Google Timelapse" view. In addition to comparison views of before-and-after images, you can now view selected scenes as time-lapse sequences generated via the Google Earth engine.

On April 20-22, NASA is celebrating our amazing home planet. Learn about the agency's activities and related resources.
