Study Notes
Global Energy Flows
- The oceans play a crucial role in determining the Earth's climate and have a high capacity to contain heat.
- Ocean circulation redistributes heat throughout the climate system.
- The interaction between the ocean and atmosphere is strong and has a significant impact on climate change.
Earth's Natural Climate Cycle
- Snow and ice cover affect freshwater availability, air temperatures, sea levels, ocean currents, and storm patterns.
- A reduction in snow cover and ice causes the Earth's surface to absorb more energy from the sun, leading to stronger warming.
Climate Variability
- Climate variability refers to variations in the mean state and other statistics of the climate on all temporal and spatial scales beyond individual weather events.
The Climate System
- The climate system consists of five components that directly interact with the atmosphere: atmosphere, hydrosphere, biosphere, geosphere, and cryosphere.
- These components jointly determine the climate of the atmosphere.
Earth Climate System
- The Earth's climate system is a compilation of the atmosphere, hydrosphere, geosphere, cryosphere, and biosphere and their interactions.
- The hydrosphere includes oceans and all other reservoirs of water in liquid form.
- The geosphere affects the flow of atmosphere and oceans through its morphology and radiative properties.
- The cryosphere plays a special role in the Earth's radiation balance and determines the properties of the deep ocean.
- The biosphere affects the composition and physical properties of air and water through respiration and other chemical interactions.
Earth's Natural Climate Cycle
- The Earth's rotation is slowing slightly with time, resulting in longer days (today is 1.7 ms longer than a day one century ago).
- The Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun, and this tilt changes between 22.1 and 24.5 degrees over a cycle of about 40,000 years.
- The shape of the Earth's orbit varies between nearly circular and mildly elliptical, causing Ice Ages with a period of 413,000 years.
