Answer:
5) All of the above are correct.
Explanation:
Carbon dioxide is a greenhouse gas. When its concentration in the atmoshpere rises above normal, it can affect the climate pattern and lead to climate change.
Carbon dioxide prevents outgoing solar radiation from escaping the earth's atmosphere and this warms the earth surface. The more the presence of the gas, the more heating that would result.
Excessive release of carbon dioxide causes a phenomenon known as global warming. Global warming is simply the warming of the globe.
The consequences includes:
- Melting of Greenland ice sheets as temperature spikes.
- Glaciers and permafrosts in temperate and polar regions will melt.
- Ocean acidification due to dissolution of excess carbon dioxide in sea water to form carbonic acid.
- There is general increase in surface temperature due to accelerated warming.
