Which of the following best describes a 'tipping point' in the context of environmental systems?
Which of the following best describes a 'tipping point' in the context of environmental systems?
- A period of increased carbon emissions followed by a decline.
- A temporary fluctuation in global temperatures.
- A threshold beyond which a system shifts to a new state with potentially irreversible consequences. (correct)
- A gradual and linear change in environmental conditions.
What is the primary relationship between carbon emissions and global warming?
What is the primary relationship between carbon emissions and global warming?
- Global warming causes an increase in carbon emissions due to melting permafrost.
- Increased carbon emissions directly cause an increase in the greenhouse effect, leading to global warming. (correct)
- Carbon emissions have no correlation with global warming.
- Carbon emissions help cool the earth by reflecting sunlight.
How do positive feedback loops primarily influence global warming?
How do positive feedback loops primarily influence global warming?
- They amplify the effects of global warming, accelerating the rate of temperature increase. (correct)
- They cause temporary decreases in global temperatures.
- They have no significant impact on global warming.
- They counteract the effects of global warming, helping to stabilize the climate.

Study Notes
- Epoch boundaries mark significant transitions in Earth's history.
- Boserup's theory posits that population growth drives agricultural intensification and innovation.
- Minimum population refers to the smallest number of individuals needed for a population to sustain itself.
- Maximum population represents the carrying capacity of an environment, the largest population it can support.
- Components of a system are the individual parts that interact to form a complex whole.
- The greenhouse effect is the process by which certain gases in the atmosphere trap heat, warming the planet.
- Global temperature increase refers to the rising average temperature of Earth's climate system.
- Ecological footprints measure the impact of human activities on the environment in terms of the area of land and water required to produce the goods consumed and to assimilate the wastes generated.
- Global warming is caused by increased concentrations of greenhouse gases in the atmosphere.
- Carbon emissions are the release of carbon dioxide and other carbon compounds into the atmosphere, largely from burning fossil fuels.
- Feedback loops are processes in which the output of a system either reinforces (positive feedback) or diminishes (negative feedback) the initial change.
- Tipping points are critical thresholds in a system that, when exceeded, lead to irreversible and often abrupt changes.
