| ES1201 | Earth System Processes | Gaurav Shukla, Manoj Kumar Jaiswal |
| Preamble |
|---|
| This course introduces issues of modern problems of global change with observational data and how the Earth responds under stress. The surface process section of the course would cover topics on how the Earth works as a system, and on global events in the history of the Earth that provide lessons for the future. The next section of the course would cover topics related to lithospheric process. |

| Earth as a system- an introduction
I. Lithospheric processes a) Isotopic reservoir: Introduction to evolution of isotopic reservoirs particularly relevant to core, mantle and crust formation. b) Exogenous processes and products: Agents and processes responsible for shaping landscapes Tectonics and landform evolution Tectonics and climate II. Atmospheric and oceanic processes in relation to climate a) Climate system concepts: state, coupling, feedback, equilibrium; formation of the atmosphere; composition of the early atmosphere; formation of oceans. b) Role of the atmosphere and oceans in energy redistribution: global energy distribution; general circulation of the atmosphere; surface and deep-ocean circulation; energy redistribution over short and long timescales; global profiles of temperature and precipitation. c) Global energy balance and climate change: fundamentals of planetary energy balance and the greenhouse effect; long-term climate regulation glacial-interglacial periods and Milankovitch cycles; long-term CO2 records; examples of climate regulation by natural factors the faint young sun paradox and the snowball earth; a critical review of the Gaia hypothesis and the Daisyworld climate system. |
