Carbon Dioxide (CO2) Emissions
Carbon dioxide (CO2) is a greenhouse gas found naturally in Earth’s atmosphere. It is also a byproduct of industrial processes and burning . The release of CO2 emissions into the atmosphere is the primary driver of . The rise in average global temperature is directly proportional to concentrations of carbon dioxide in the atmosphere, measured […]
Carbon Sequestration
Storing carbon dioxide (CO2) in forests, oceans, or underground geological formations to slow down or prevent the buildup of CO2 concentrations in the atmosphere. The process aims to counteract the increase in – the main contributor to . Sequestration can occur naturally in carbon sinks such as forests and oceans. It is also possible through […]
Circular Carbon Economy
A framework to manage and reduce carbon emissions that was proposed and promoted by Saudi Arabia when it hosted the G20 summit in 2020. It resembles the 3R model (Reduce, Reuse, Recycle) and adds further elements to it, such as and . While the basic assumption is correct and necessary, namely that carbon can and […]
False Solutions
Measures, often of technical nature, that have been proposed to deal with the , often by fossil fuel corporations and their lobbies, but which don’t lead to any substantial outcomes in dealing with the climate crisis. Examples are , carbon trading, REDD+, , and geoengineering.
Hydrogen
Hydrogen is the most abundant element in the universe. It hardly occurs in nature in separate form, because it easily reacts with other elements into more stable substances such as water. In recent years, hydrogen has been investigated as an energy carrier which could store energy. It is important to note that hydrogen is thus […]
Run-Away Climate Change
Run-away climate change refers to that “feeds on itself” through amplifying feedback where the impacts of heating cause further heating. The easiest way to visualize it is to imagine a line of domino pieces – when the first one tips over, it leads to the next one falling and so on. Once started, it is […]
