Some 7,000 years ago, West Antarctica’s ice sheet retreated, most likely driven by warmer ocean currents slipping under the ice. This could happen again – unless we cut emissions fast.

NASA’s vision: To reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind.
To do that, thousands of people have been working around the world – and off of it – for 50 years, trying to answer some basic questions. What’s out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?
NASA conducts its work in three principal organisations, called mission directorates:
Aeronautics: pioneers and proves new flight technologies that improve our ability to explore and which have practical applications on Earth.
Human Exploration and Operations: focuses on International Space Station operations and human exploration beyond low Earth orbit.
Science: explores the Earth, solar system and universe beyond; charts the best route of discovery; and reaps the benefits of Earth and space exploration for society.

The aurora is one of nature’s most spectacular sights, a dazzling glow in the upper atmosphere driven by space weather.
Millions of dollars have gone into California’s forest carbon offset program – with little new carbon storage to show for it, a new study suggests.
Marine heatwaves will happen so often that reefs will struggle to weather successive bleaching events.
A closer look at how ice cover changed through the months offers some important insights into the role of climate change and why every year isn’t a record.
Tesla crashes and the investigations that follow generate a lot of headlines, but the dangers of automotive automation are industrywide. The common denominator is the human behind the wheel.
Scientists previously underestimated aquatic methane emissions. We must use this new information to stop methane derailing our attempts to stabilise the Earth’s temperature.
The US is formally back in the Paris climate agreement as of today. As one of the world’s largest greenhouse gas emitters, it has a lot of work to do, with food security, health and safety at stake.
The 2020 wildfire season shattered records across the West. It’s part of a trend that’s headed in a dangerous direction.
Nuestros últimos estudios sugieren que el metano, un gas de efecto invernadero más potente que el dióxido de carbono, se está acumulando en la atmósfera debido a la actividad humana.
A new assessment found substantial warming is much more solidly assured than we thought.
In Australia, methane emissions from fossil fuels are rising due to expansion of the natural gas industry, whereas agriculture emissions are falling.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
The deep and dark web can be a scary place, but modern open-source technologies funded by the Defense Department can help explore it.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
Extreme wet years are getting wetter and more common. This means Australia’s terrestrial ecosystems will play a larger role in the global carbon cycle.
Scientists say they’ve found fossils showing life existed on Earth 3.7 billion years ago. How good is the evidence? And what does it mean for the search for life elsewhere in our solar system?
Measuring time is a crucial part of navigation – particularly in space, where exacting precision is called for. The DSAC is poised to make a change that will aid future deep space missions.
Hundreds of cities worldwide have pledged to act against climate change. New York City’s experience rebuilding after Hurricane Sandy offers useful lessons about making urban areas more resilient.
Dawn’s mission director and chief engineer describes his ‘dream come true’ job – and how the new data coming back from Ceres could unlock some of the secrets of the earliest days of our solar system.
