How green sand could capture billions of tons of carbon dioxide

How green sand could capture billions of tons of carbon dioxide

Later this year, Project Vesta plans to spread a green volcanic mineral known as olivine, ground down to the size of sand particles, across one of the beaches. The waves will further break down the highly reactive material, accelerating a series of chemical reactions that pull the greenhouse gas out of the air and lock it up in the shells and skeletons of mollusks and corals.

Megaprojects to reverse climate change

This video covers technologies to control the temperature of the planet, either by reducing greenhouse gases or by diminishing the amount of sunlight hitting the planet:

4 Megaprojects That Could Reverse Climate Change | Answers With Joe
  • Biomass energy with carbon capture storage (BECCS)
  • Direct Air Capture
  • Carbon capture and sequestration
  • Artificial volcanoes
  • Stratospheric aerosol injection
  • Satellites in orbit

It is time to start capturing carbon out of the atmosphere

This article makes the case for pulling carbon dioxide back out of the atmosphere starting now:

There Are So Many Ways Of Capturing Carbon Dioxide: We Must Start Using Them Now

The article offers several options:

The article does not think highly of the value of direct air capture, but there is a lot to like about this technology:
