Geology and Climate Science
Introduction:
Geology is the study of the earth’s structure and the processes that shape it. One of these processes is climate change. Climate science is the study of how the earth’s climate system works, how it has changed in the past, and how it might change in the future. Geology and climate science are closely related, as understanding the geological history of the earth is crucial to predicting and understanding climate change.
Key Concepts:
- Plate tectonics: the movement of the earth’s plates, which affects the distribution of continents and oceans and can lead to changes in climate.
- Paleoclimate: the study of climate before the instrumental record, using evidence from geological and biological sources.
- Carbon cycle: the movement of carbon between the earth, oceans, atmosphere, and living organisms, which is key to understanding climate change.
- Ice ages: periods of time when large areas of the earth’s surface are covered in ice, which have occurred periodically throughout earth’s history.
- Greenhouse gases: atmospheric gases that trap heat and contribute to global warming.
Equations and Formulas:
- Carbon dioxide concentration: CO2 = (mass of CO2 Γ· total mass of air) x 100%
- Earth’s energy balance: Energy in = Energy out (if there is a net gain or loss of energy, it affects the earth’s temperature)
Examples:
- The study of the earth’s past climate has shown that temperature changes are often accompanied by changes in atmospheric CO2 levels.
- Plate tectonics has led to the movement of continents, which has affected ocean currents and their ability to transport heat around the earth.
- The ice ages are believed to have been triggered by changes in the earth’s orbit and tilt, which affected the distribution of solar radiation.
- The burning of fossil fuels has led to a significant increase in atmospheric CO2 levels, which has contributed to global warming.
