Located in the Arctic near the North Pole, Greenland is covered by a massive ice sheet three times the size of Texas and a mile deep on average. Greenland is warming almost twice as fast as Antarctica, which is causing the ice to melt and raise global sea levels. NASA is monitoring Greenland’s ice sheet […]

For over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our ocean to warm and glaciers to melt, resulting in sea level rise. Since 1880, the global sea level has risen 8 inches; […]

NASA doesn’t study just the stars and planets; it is also concerned with the soil beneath your feet. Studying the moisture in the top two inches of the soil from space with a satellite named “SMAP” can help weather forecasters predict flash floods, farmers grow more crops, and communities plan for drought.

Since 1978, NASA has been monitoring ocean winds via scatterometry, the data of which has improved weather and hurricane forecasts and helped us better understand global climate patterns. Knowing which way the wind is blowing over water is critical for industries such as shipping and fishing, and it helps predict unusual weather phenomena such as […]

The force of gravity not only keeps us from floating away, it lets NASA study Earth’s water & ice from space. Using a pair of twin satellites named GRACE, we can monitor where our planet’s water is going, even when it is underground.

Greenhouse gases are vital to life on Earth, but the growing concentration of certain gases, such as carbon dioxide, is throwing the planet’s delicate balance out of whack. NASA is on the case, studying carbon dioxide on a global scale and its effects on our weather and climate.

Earth’s average temperature has risen over 1º F in the past century. It is projected to rise an additional 3º to 10º over the next 100 years. Data from NASA’s global network of satellites, airborne missions and surface monitoring systems is used to build climate models that help us understand the causes and effects of […]

NASA doesn’t just explore outer space! Since 1959, with the launch of the first weather satellite, NASA has been studying our home planet on a global scale. NASA monitors Earth’s vital signs via satellites and airplanes, sends scientists to the far corners of the land and under the ocean, and develops computer models of Earth’s […]

Before the Industrial Revolution, Earth’s climate changed due to natural events such as volcanic activity and solar energy variations. These natural events still contribute to climate change today, but their impact is very small compared to the growing levels of greenhouse gases added to the atmosphere by humans burning fossil fuels. NASA’s ongoing Earth science […]

Earth is a complex, dynamic system we do not fully understand. To learn more about it, NASA, as the agency with access to space, was tasked with launching the first weather satellite back in 1960. Today, NASA uses satellites, aircraft and even an occasional boat to study our planet’s air, land and water. It’s called […]
