causes uncontrolled photosynthesis
removes carbon dioxide from the oceans
disrupts the natural cycling of other greenhouse gases

How is the atmosphere involved in the greenhouse effect?
It transforms light energy from the Sun into thermal energy that warms the surface of Earth.
Gases in the atmosphere trap and redirect heat reflected from the surface of Earth.
Gases magnify the heat of the Sun as it passes down through Earth's atmosphere.
Heat from the surface of Earth is absorbed by gases and radiated into space.
