Answer:
Factors 1 and 2 are natural factors; factor 1 is also a human-induced factor.
Explanation:
Ocean s are warming up daily with temperatures elevating due to variations in Sun's energy, changes in reflectivity property of Earth and surfcae and the greenhouse effect. With increased industrial revolution, activities leading to massive use of fossil fuels ,deforestation and other processes release huge amounts of carbondioxide to the atmosphere.The eefect is planet warming.Warming harms marine life, cause stronger storms like hurricane and rises the sea levels.This shows factor one, increased ocean temperature a natural factor and a human induced one.
Ice masses in areas such as the Greenland have decreased in quantity due to elevated tempeartures experienced globally.However, greenhouse effect has partially caused the melting of ice and glaciers.
