Summary
Many factors operating as components of Earth's climate system govern the spatial and temporal variability of climate. The ocean plays a major role in worldwide weather and climate. Earth's climate
system responds to some initial disturbance in the system, with these responses often resulting in positive or negative feedback in the system. Feedback is positive when it reinforces the initial input and
negative when it suppresses the initial input. Polar amplification demonstrates the effect of a positive feedback in the climate system. The reduction in sea-ice cover and snow in the Arctic reduces regional
albedo. As the region warms, greater evaporation adds more water vapor into the atmosphere, which enhances warming. As the region continues to warm, methane is being released at higher rates from
permafrost and methane hydrates, accelerating warming in the region. This is all a part of the ice-albedo feedback.
