Final answer:
The three things required to reduce the long-term impacts of climate change are adaptation, mitigation, and geoengineering.
Step-by-step explanation:
The three things that are required to reduce the long-term impacts of climate change are adaptation, mitigation, and geoengineering.
Adaptation refers to adjusting to the changes caused by climate change, such as building resilient infrastructure and implementing water management strategies.
Mitigation involves reducing greenhouse gas emissions to prevent further climate change. This can be achieved through using renewable energy sources, improving energy efficiency, and implementing carbon offsetting.
Geoengineering refers to deliberate interventions in the Earth's climate system to counteract the effects of climate change, such as removing carbon dioxide from the atmosphere or modifying cloud formation.
