Your body temperature rises as you walk around outside in Bangladesh on a hot afternoon. The sensors in your skin detect the rise in your surface temperature so you start to sweat.
Positive Feedback
Negative Feedback
Higher temperatures cause more evaporation which leads to more water vapor in the atmosphere. Water vapor is a greenhouse gas so will trap more heat so the atmosphere will warm more.
Positive Feedback
Negative Feedback
As carbon dioxide levels in the atmosphere rise, the temperature of the Earth rises. As the Earth warms the rate of photosynthesis in plants increases, more carbon dioxide is therefore removed from the atmosphere by plants, reducing the greenhouse effect and reducing global temperatures.
Positive Feedback
Negative Feedback
As the Earth warms, ice cover melts, exposing soil or water. Albedo decreases (albedo is the fraction of light that is reflected by a body or surface). More energy is absorbed by the Earth’s surface. Global temperature rises. More ice melts.
Positive Feedback
Negative Feedback
As the Earth warms, organic matter in soil is decomposed faster, more carbon dioxide is released. The enhanced greenhouse effect occurs, the Earth warms further and rates of decomposition increase
Positive Feedback
Negative Feedback
As the Earth warms, evaporation increases. Snowfall at high latitudes increases, icecaps enlarge. More energy is reflected by increased albedo of ice cover. The Earth cools. Rates of evaporation fall.
Positive Feedback
Negative Feedback
As the Earth warms, polar icecaps melt, releasing large numbers of icebergs into oceans. Warm ocean currents such as the Gulf Stream are disrupted by additional freshwater input into oceans. Reduced transfer of energy to the poles reduces temperature at high altitudes. Ice sheets reform and icebergs retreat. Warm currents are re-established.
