Scientists have discovered that most freshwater fish may have originated in ancient oceans, not rivers. Fossils and DNA now reveal a surprising evolutionary journey that reshapes biology.
Some icy moons may have subsurface oceans that boil near thin ice layers. Despite this, life could survive deeper below, say recent scientific findings.
French President Emmanuel Macron and First Lady Brigitte Macron welcomed global leaders to an opening dinner in Nice on June 8 for the United Nations Ocean Conference (UNOC3), held at the historic Negresco hotel. The conference, running from July 9 to 13, seeks to boost support for a treaty to protect ocean biodiversity, which currently lacks enough signatories to take effect. Macron emphasized France’s leadership in marine protection, downplaying the absence of U.S. President Donald Trump and his administration. He expressed hope that more than the current 30 nations will commit to halting deep-sea exploitation. Highlighting five interconnected ocean crises—biodiversity loss, water quality, food security, health, and climate change—Macron called for increased European funding for scientific deep-sea research. France is co-hosting the event with Costa Rica, a country recognized for environmental stewardship. Macron urged a unified global response, describing unregulated deep-sea exploitation as reckless and scientifically unjustified.
NASA's PACE mission will deepen our understanding of oceans, atmosphere, and climate, providing observations of microscopic marine organisms called phytoplankton and essential data on clouds and aerosols.
PACE aims to unravel the mysteries surrounding microscopic life in water and airborne particles in the atmosphere, shedding light on their impact on Earth's climate and air quality
The rate of global warming has slowed after strong rises in the 1980s and 1990s, even though all the 10 warmest years since reliable records began in the 1850s have been since 1998.
Super-Earths could have oceans of liquid metal and life-protecting magnetic shields, scientists say.
The cost of damage to the world's oceans from climate change could reach USD 2 trillion a year by 2100 if measures to cut greenhouse gas emissions are not stepped up, a study by marine experts said on Wednesday.
