  COP28 By Jonah Fisher & Mark Poynting BBC News Climate & Science The future of fossil fuels - particularly whether to agree to phasing out coal, oil and gas - is arguably the key issue of the COP28 climate summit in Dubai. Any agreement is likely to rely on ambitious measures to capture and remove carbon dioxide (CO2) - the main gas responsible for global warming.   Techniques range from capturing CO2 before it is released at power stations and storing it deep underground, to using trees or machines to suck CO2 directly out of the air.   Here's a quick guide to the different types of carbon capture and removal, why they are needed, and their limitations.   What is carbon capture and storage and how does it work? Carbon capture and storage facilities aim to prevent CO2 produced from industrial processes and power stations from being released into the atmosphere.   Most of the CO2 from burning fossil fuels is captured, transported, and th...

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...
