As the earth has a closed atmosphere, there has always been the same amount of carbon on the earth, but it is in a constant state of change, transitioning from gas to solid to liquid and moving between the atmosphere and the earth. This process is called the carbon cycle, and it is ...
As space is extremely cold, the CO2out there is in the form of ice – CO2freezes at -56.4°C (-69.5°F). When stars formed out of these nebulae, some of the CO2ice became part of the planets. That is why there is carbon dioxide not just on Earth, but also on Mars, Venus and ...
In 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 investigate the ways in which...
