Giant underwater plumes triggered by 7-story waves at Nazaré captured off Portuguese coast
Earth from space A 2020 satellite photo shows the immense power of 7-story waves crashing along the Portuguese coast. Later the same day, a surfer rode a 101-foot-tall wave at Nazaré, setting a new world record.
Last year, the oceans absorbed a record-breaking amount of heat — equivalent to 12 Hiroshima bombs exploding every second
In 2025, the ocean absorbed an extra 23 zettajoules of heat energy in 2025, breaking the ocean heat content record for the ninth consecutive year.
'The scientific cost would be severe': A Trump Greenland takeover would put climate research at risk
Trump's calls for a takeover of Greenland puts open scientific collaboration that is helping our understanding of the threat of global sea-level rise at risk.
Forced closure of premier US weather-modeling institute could endanger millions of Americans
From high-wind forecasts and wildfire behavior to floods, aviation hazards, air quality and space weather, science developed at the National Center for Atmospheric Research informs decisions that aim to reduce risk.
Scars from ancient 'megaquakes' at Cascadia subduction zone discovered in deep-sea landslides
Large subduction-zone earthquakes leave scars on the continental slope in the deep sea.
New map of Antarctica reveals hidden world of lakes, valleys and mountains buried beneath miles of ice
The map shows diverse geological features shaping Antarctic glaciers from below, which can improve climate models of ice melt.
Fragment of lost tectonic plate discovered where San Andreas and Cascadia faults meet
A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating earthquake risk at the Cascadia subduction zone.
Scientists watch microscopic plant 'mouths' breathing in real time with palm-sized tool
Scientists say their Stomata In-Sight tool can observe plants "breathe," which could be used to bioengineer crops that require less water, making them potentially more resilient to climate change.
18 of Earth's biggest river deltas — including the Nile and Amazon — are sinking faster than global sea levels are rising
Worldwide, millions of people live in river deltas that are sinking faster than sea levels are rising, research suggests. This exacerbates the risk of catastrophic coastal flooding and land loss.
Mega-iceberg A23a, formerly the world's largest, turns into bright 'blue mush' as it finally dies after 40 years at sea
New satellite photos reveal that one of the world's largest and longest-lived icebergs, A23a, has developed vibrant blue striations on its surface. The striking snaps hint that the "megaberg" will soon disappear forever, ending a surprisingly eventful four-decade-long saga.
