The aurora is one of nature’s most spectacular sights, a dazzling glow in the upper atmosphere driven by space weather.
Redwood forests like this one in California can store large amounts of carbon, but not if they’re being cut down.
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.
Arctic sea ice has been declining overall since NASA began tracking it by satellite in the 1970s.
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.
Advanced driver-assist systems can lull drivers into taking their hands off the wheel and eyes off the road when they shouldn’t.
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.
Through the Paris Agreement, the world’s countries agreed to work to keep global warming well under 2 degrees Celsius.

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?
A geographical map depicting hotbeds of dark web activity related to illegal products. Larger circles indicate more activity.
The deep and dark web can be a scary place, but modern open-source technologies funded by the Defense Department can help explore it.
Rice paddies are one of the major sources of methane in agriculture.
Methane concentrations in the atmosphere are growing at a faster rate than any time in the past 20 years.
Dry period in semi-arid central Australia.
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.
If life survived on Earth 3.7 billion years ago, why not elsewhere in the solar system?
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?
DSAC is prepping for a yearlong experiment to characterize and test its suitability for use in future deep space exploration.
Jet Propulsion Laboratory
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.
Earth’s city lights.

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.
Ceres, as seen by NASA’s Dawn spacecraft on December 10, around a crater chain called Gerber Catena.
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.
Fires, such as this one in eastern Sierra Leone, are an annual occurrence across Africa.
On the African continent, more fire for crops leads to less rainfall.
