Study Notes

Climate Feedback Mechanisms Explained

For every watt per square meter of radiative forcing absorbed by land or water, the planet's climate increases by 0.9 to 1.8 degrees Fahrenheit (0.5 to 1.0 degrees Celsius).
Ice albedo feedback is a positive climate mechanism where melting ice leads to more available ocean water that absorbs sunlight, perpetuating the cycle of ice melting and heat being trapped.
Warming ocean waters lead to sea level rise, affecting coastal communities and ecosystems.
Oceans absorb more solar radiation than ice and land surfaces, releasing water vapor and aerosols into the atmosphere, facilitating cloud formation and generating precipitation.
Oceans absorb carbon dioxide and store it deep within their basins, contributing to the greenhouse effect.
Oceans and forests act as reservoirs for carbon dioxide, absorbing about one-third and one-quarter of human emissions, respectively.
Carbon dioxide absorption in oceans leads to acidification, affecting marine life and coral reefs.
Warmer oceans lead to less phytoplankton and reduced carbon absorption, while terrestrial plants benefit from increased carbon dioxide but are affected by deforestation and wildfires.
Negative feedback mechanisms, like the water vapor-cloud feedback loop and atmosphere-biota interactions, help limit the amount of heat being trapped and stabilize Earth's climate system.
The water vapor-cloud feedback loop involves the development of low-lying clouds that reflect some of the sun's radiative forcing, cooling the Earth's surface.
Atmosphere-biota interactions involve plant and animal species absorbing heat to conduct photosynthesis, releasing water vapor into the atmosphere, which contributes to cloud formation and reflects radiant energy back into space.
Overall, these feedback mechanisms play crucial roles in regulating Earth's climate, with positive feedback mechanisms exacerbating climate change and negative feedback mechanisms helping to stabilize it.
