Billions of years ago, wind, heat and the rotating Earth formed currents just as they're produced today — but their paths would have been wildly different.
Flashy new videos of the plant shameplant (Mimosa pudica), which is renowned for its ability to rapidly fold up its leaves, reveal how chemical and electrical signals help to trigger its lightning reflexes.
New fund would aid responses to floods, fires and storms. But a failure to address warming and greenhouse gas emissions undercuts the funding success, critics say.
A pair of new studies has revealed 'highly unlikely' phytoplankton blooms appearing near the seafloor and under sea ice at both Earth's poles.
A new method of using the machinery of photosynthesis to make methane is 10 times more efficient than previous attempts.
A global drop in oxygen levels about 550 million years ago led to Earth's first known mass extinction, new evidence suggests.
Staving off the worst impacts of climate change means preventing global temperatures from rising more than 1.5 degrees Celsius above preindustrial levels. But CO2 emissions are so high that we are slated to cross that line within a decade.
A United Nations report warns of imperiled glaciers at iconic World Heritage sites — but climate action could save most of them.
Fossils called stromatolites from Western Australia were created by microbes 3.48 billion years ago.
Light-up fish and ancient volcanic structures are among the discoveries of a new expedition to map the remote Cocos Islands in the Indian Ocean.
A new satellite image shows that the world's largest iceberg, A-76A, has entered the Drake Passage, a waterway that contains a fast-moving ocean current that will send the mighty berg on a one-way trip to its watery grave.
On Nov. 3, a solar storm caused a temporary crack in Earth's magnetic field. The resulting hole enabled energetic particles to penetrate deep into the planet's atmosphere and set off extremely rare pink auroras.
As global temperatures rise, the ecology of Antarctica is already changing, but Earth's climate would have to change drastically before the continent could support agriculture and permanent settlers.
The biggest blasts come from above, while volcanic eruptions and human-caused detonations have also unleashed incredible levels of energy.
The rapid decline of the British-Irish Ice Sheet thousands of years ago may hold lessons for how melting ice sheets in Greenland and Antarctica will influence sea-level rise in the future.
Researchers have accurately measured the height of the eruption plume from the undersea volcano that erupted in Tonga in January. The results confirm that it is the tallest of its kind ever recorded.
Reference Photosynthesis is the process plants, algae and some bacteria use to turn sunlight, carbon dioxide and water into sugar and oxygen.
