i. Possible consequences include altered climate and increased sea level.

ii. Heat energy radiated by the earth is captured by atmospheric molecules.

Explanation:

Global warming involves changes in the weather and the environment. Thus, warmer temperatures make ice and snow melt, which causes sea levels to rise. Besides, ice and snow reflect light, and because liquid water consumes light energy, it is released again as heat, which is also absorbed by molecules living in the atmosphere.
