How does Earth’s climate and environment respond to the seasonal cycle now and in the past.
Geologists study climate of the past to learn more about Earth’s climate in the present and future. However, climate is usually studied on a long timescale, while rapid changes in climate (like those associated with the present global warming) are also very important to understand. The study of seasonal differences in the geological past helps us to understand not only how Earth’s climate and environment behaved on average over a long time period, but also how dynamic it was and how short term, extreme changes took place. This will help us understand changes in climate and environment that take place on the human timescale.
