Is Carbon Capture Essential to Fighting Climate Change?: A Debate 50 min.

The main cause of climate change is the emission into the atmosphere of carbon dioxide (CO2), a gas that is released by the burning of fossil fuels such as oil and coal. To reduce these emissions and slow climate change, some scientists have developed a technology called carbon capture and storage, in which CO2 is extracted and stored in underground facilities. In early 2023, Exxon Mobil, one of t...
