Global Warming Cause
Greenhouse gases, especially carbon dioxide (CO2), trap heat in the atmosphere, preventing the planet from cooling.
Human industrial activities, like burning fossil fuels (coal, petrol), are the main cause of this CO2 buildup.
Human Response to Climate Change
Adaptation: Adjusting to the impacts of a warming world.
Mitigation: Reducing CO2 emissions to slow down climate change.
Carbon Capture and Sequestration (CCS)
CCS involves capturing CO2 from emission sources (e.g., power plants) or the atmosphere, converting it, and storing it safely.
CCS has been controversial, as some argue it might allow continued pollution by removing CO2 without addressing its source.
Study Findings
A study published in Environmental Science & Technology suggests that CCS technologies are more expensive than switching to renewable energy.
It would cost 9-12 times more for countries to use CCS to offset CO2 emissions than to fully switch to wind, water, and solar power.
