By the end of studying this unit, participants should be able to.
Here are some questions for you and your students/learners to think about:
Paleoclimatology is the study of the climate that existed before humans began collecting instrumental measurements of weather (for example, temperature from a thermometer, precipitation from a rain gauge, sea level pressure from a barometer, wind speed and direction from an anemometer).
Paleoclimatology: The study of past climate. The word is derived from the Greek root “paleo” which means “ancient,” and the term “climate”. From the paleooclimate perspective, climate change is normal, and part of the Earth’s natural variability related to interactions among the atmosphere, ocean and land as well as changes in the amount of solar radiation reaching the Earth. The geologic record includes much evidence of large-scale climate changes.
Some of the major factors resulting in climate change in the past, sometimes so severe as to result in mass extinctions, are: For more on this method, see the Methods & Processes book, p. 14.
Teaching Climate Change 17 Volcanic eruptions which cause vast quantities of carbon dioxide to be emitted into the atmosphere, ash clouds blocking sunlight, potentially acid rain and large-scale floods of basalt lava; Plate tectonics and continental drift; Sea level falls from the sinking of tectonic plates or sustained global cooling; and Asteroid impacts, the largest of which produced a crater of more than 100km wide.
