Ask NASA Climate

The Surface Water and Ocean Topography mission offers the first taste of the detailed perspectives of Earth’s surface water that its cutting-edge instruments will be able to capture.

Observations from space show that the rate of sea level rise is increasing. Knowing where and how much rise is happening can help coastal planners prepare for future hazards.

A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.

NASA scientists have mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests.

Mangroves help protect against the effects of climate change in low-lying coastal regions. NASA and partners are using satellite data to monitor the health of these ecosystems so local experts can respond.

This source accounts for about 10% of all the water that enters this highly productive farmland, including rivers and rain.

Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA.

Extreme rainfall during Tropical Storm Nalgae (locally called Paeng) on Oct. 29, 2022, caused destructive flooding and landslides in the southern Philippines.

A warming planet is leading to more frequent and intense rainfall, causing more landslides. A team of master’s students came up with a novel approach to helping NASA study these events on a large scale.

A case study involving Europe’s largest coal-fired power plant shows space-based observations can be used to track carbon dioxide emissions – and reductions – at the source.

Climate change is adding to food insecurity, along with a growing population and chronic world hunger. That's where the agency's Earth science data come in.

Climate change may affect the production of maize (corn) and wheat as early as 2030, according to a new NASA study. (Image credit: Melissa Askew/Unsplash)
