What is CO2? Carbon dioxide (or CO2) is a colourless and odourless naturally occurring gas in the earth’s atmosphere which is made up of one carbon atom and two oxygen atoms. As a greenhouse gas (GHG), it traps heat, making sure the planet isn’t uninhabitably cold. However, fast ...
Carbon dioxide is a natural greenhouse gas, commonly produced by the air we exhale. At higher levels, CO2 affects productivity, sleep and infectious disease transmission. Learn more on CO2 health effects, safe CO2 levels, and ways to reduce CO2.
GAS industryPETROLEUM reservoirsIn this article, I focus on carbon capture and storage (CCS), a controversial climate change mitigation technology that operates by collecting carbon dioxide from point sources and depositing it in underground locations, such as depleting oil reservoirs. Specifically, I ...
. That is why there is carbon dioxide not just on Earth, but also on Mars, Venus and other planets. Earth’s surface is considerably warmer than space, so our carbon dioxide melted and became a gas – the CO2molecules float in the air. Even though a tiny percentage of our atmosphere ...
