Start-ups are adding antacids to the ocean to slow global warming. Will it work?

Start-ups are adding antacids to the ocean to slow global warming. Will it work? A New York experiment is part of a commercial race to develop ocean-based technologies to extract carbon dioxide from the atmosphere.                                                                                 NEWS FEATURE  28 June 2023 A team takes a core sample of ocean bottom sediments at North Sea Beach, New York.

She’s looking for green mineral crystals that her team added to the sand last year. If all goes as planned, these olivine crystals will cause the ocean to absorb more carbon dioxide from the atmosphere — a cl...

The North Atlantic is experiencing a ‘totally unprecedented’ marine heat wave

  The North Atlantic is experiencing a ‘totally unprecedented’ marine heat wave By  Laura Paddison , CNN Updated 5:44 PM EDT, Tue June 20, 2023 A map shows the sea surface temperature anomaly on Sunday, June 18. Temperatures off the coast of the UK and Ireland are several degrees higher than usual. Temperatures in parts of the North Atlantic Ocean  are soaring  off the charts, with an “exceptional” marine heat wave happening off the coasts of the United Kingdom and Ireland, sparking concerns about impacts on marine life. Parts of the North Sea are experiencing a  category 4 marine heat wave  – defined as “extreme” – according to the National Oceanic and Atmospheric Administration. In some areas, water temperatures are up to 5 degrees Celsius (9 Fahrenheit) hotter than usual. Global oceans have been exceptionally warm for months. April and May saw the  highest ocean surface temperatures  for those two months since records began in 1850. The regiona...

Humans pump so much groundwater that Earth’s axis has shifted, Geophysicist Ki-Weon Seo from Seoul National University has discovered that study finds

Humans pump so much groundwater that Earth’s axis has shifted,  Geophysicist Ki-Weon Seo from Seoul National University has discovered that study finds   By Mindy Weisberger, CNN Updated 7:42 PM EDT, Mon June 26, 2023 (https://edition.cnn.com/2023/06/26/world/pumping-groundwater-earth-axis-shifting-scn/index.html) Groundwater extraction is a significant factor in the tilting of Earth's rotational axis, according to a new study. CNN  —  Humans’ unquenchable thirst for groundwater has sucked so much liquid from subsurface reserves that it’s affecting Earth’s tilt, according to a new study. Groundwater provides drinking water for people and livestock, and it helps with crop irrigation when rain is scarce. However, the new research shows that persistent groundwater extraction over more than a decade shifted the axis on which our planet rotates, tipping it over to the east at a rate of about 1.7 inches (4.3 centimeters) per year. That shift is even observable on Earth’s s...
