Answer:

1. DEFORESTATION

2. WILD FIRE

3. FLOOD

Explanation:

DEFORESTATION

- During photosynthesis, tropical forest trees, like other green plants, take in carbon dioxide and emit oxygen. When trees are chopped down and burned or left to rot, the carbon they have stored is released into the atmosphere as carbon dioxide. And this is how forest degradation and deforestation contribute to global warming.

WILD FIRE

- Although wildfires emit greenhouse gases and aerosols such as carbon dioxide, methane, and black carbon, the plants that re-colonize burnt regions take carbon dioxide from the atmosphere, resulting in a net neutral impact on global warming.

FLOOD

- Floods, for instance, become more of a problem when more pavement and other impervious surfaces are constructed over a region. Despite the fact that climate change is raising future flood hazards, most models fail to account for the impact of global warming, such as sea level rise.
