PROBLEM SOLVING ACTIVITY CLIMATE CHANGE AND …

Student Sheet 1 PROBLEM SOLVING ACTIVITY : CLIMATE CHANGE AND FEEDBACK LOOPS Systems are made up of parts and the interactions between them. They are composed of: Storages of matter/energy: tree biomass in trunk & leaves. Flows: inputs & outputs: light, oxygen and heat. Processes which transfer or transform the energy/matter): photosynthesis. Feedback loops: affecting the stability of the system. To be stable, all systems need to be self-regulating. Feedback loops permit systems to adjust their response to CHANGE (forcing factors) to return to stable conditions. Systems diagrams contain boxes that show circles and arrows which indicate flows.

In climate change, a feedback loop is something that speeds up or slows down a warming trend. A positive feedback accelerates a temperature rise, whereas a negative feedback slows it down. Student Sheet 2 Scientists have identified several positive feedbacks loops in the climate system.

TEACHER BACKGROUND: NATURAL CLIMATE CHANGE

means cooler summers and milder winters. Slow changes in the Earth’s orbit lead to small but climatically important changes in the strength of the seasons over tens of thousands of years. Climate feedbacks amplify these small changes, thereby producing ice ages. Solar variations - The Sun is the source of energy for the Earth’s climate system.

Coral reef calcification and climate change: the effect of ...

gml.noaa.gov

corals display different sensitivities to changes in aragΩ and SST [Reynaud et al., 2003]. Considering that both these environmental parameters are likely to change considerably in the future, additional experiments on a variety of differing coral species will be crucial to obtain a better understanding of future coral reef stability.

TEACHER BACKGROUND: SPECIFICS OF HEAT TRANSFER

gml.noaa.gov

In a new scenario, a metal can containing hot water is placed in a Styrofoam cup containing cold water. Heat is transferred from the hot water to the cold water until both samples have the same temperature. The transfer of heat from the hot water through the metal can to the cold water is referred to as conduction.
