Answer 2

On Earth, an atmosphere containing naturally occurring amounts of greenhouse gases causes air temperature near the surface to bewarmer by about 33 °C (59 °F) than it would be in their absence. Without the Earth's atmosphere, the Earth's average temperature would be well below the freezing temperature of water.Global warming is projected to have a number of effects on the oceans. Ongoing effectsinclude rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification
.Global warming is caused by human activities such as burning fossil fuels, deforestation and farming. ... Plants play an important role in regulating the climate because they absorb carbon dioxide from the air and release oxygen back into it. Forests and bushland act as carbon sinks ...
