Update: Carbon Dioxide Concentration
April's global average concentration (amount) of atmospheric carbon dioxide was about 417 parts per million (ppm), a roughly 50% increase since 1750 due to human activities, like burning fossil fuels and land-use changes.

NASA's Cynthia Rosenzweig Receives 2022 World Food Prize
A NASA climate researcher has received the 2022 World Food Prize, comparable to a Nobel Prize for food and agriculture.
International Satellite to Track Impacts of Small Ocean Currents
The Surface Water and Ocean Topography mission will explore how small-scale currents help the ocean absorb atmospheric heat and carbon, moderating global temperatures and climate change.
From Weather Forecasting to Climate Change, NASA's AIRS Builds a Legacy
The Atmospheric Infrared Sounder helps researchers predict weather, analyze air pollution, monitor volcanoes, and track a changing climate. And there’s more.
Graphic: When Emissions Stop, Warming Stops
Decades of research show that global warming is caused primarily by greenhouse gas emissions from the human burning of fossil fuels. When those emissions stop, warming stops within a few years. Learn more at the link above.
Video: JPL and the Space Age: Sky High (Video)
NASA has been studying and monitoring the health of our home planet for decades, using balloons, aircraft, satellites, and even the International Space Station. Watch “Sky High,” the 16th documentary in the series “JPL and the Space Age."
Images of Change: Ice Breakup at Land Glacier, Antarctica
In March, old sea ice crumbled away as new ice formed off a glacier and its surrounding coastline. Visit the link above to see the details from space.
Images of Change: Farming the Egyptian Desert
Urbanization and saltwater intrusion are eating away at Egypt's farmland. One response is an effort to extend farming into the Sahara Desert. NASA's Landsat 5 and 8 satellites captured this change. (Also see "Nile Delta's Disappearing Farmland" below for another view.)
Images of Change: Nile Delta's Disappearing Farmland
Rapid population growth and expanding cities are diminishing one of Egypt’s most precious resources. Satellite images show the impact of human activity around the cities of Tanta and El Mahalla El Kubra between 1984 and 2021.
