Feedback loops Flashcards
What is the natural regulation of Earth’s temperature?
Natural regulation includes polar ice caps and glaciers reflecting sun rays, which cools the Earth. This represents a negative feedback effect, stabilizing the climate
Explain the positive feedback loop of global warming.
Global warming triggers ice melt, reducing reflection of solar radiation, which leads to more warming. This creates a positive feedback loop, driving further warming.
What is a tipping point in the context of climate change?
A tipping point is a threshold that, when crossed, results in an abrupt shift from one stable state to another. Tipping points can lead to irreversible changes in environmental conditions.
What is a “tipping cascade”?
A tipping cascade occurs when a system passes a tipping point, and positive feedback mechanisms propel it further into a new state with different environmental conditions.
What socio-economic challenges are associated with sustainable development?
socio-economic challenges of sustainable development include disparities in economic growth, rapid population growth in some regions, widespread poverty, dependence on natural resources, and inadequate governance.
How does population growth affect sustainable development?
Population growth can strain resources, lead to poverty, and hinder sustainable development efforts, particularly in regions with rapid population growth.
What are some determinants of fertility rate?
Factors influencing fertility rate include child mortality, access to family planning services, women’s participation in the labor force, age of marriage, urban vs. rural divide, and cultural norms.
hat is the impact of rapid urbanization and international migration?
Rapid urbanization and international migration can affect livability, economic growth, and social stability, creating socio-economic challenges in some regions.
How does climate change affect sustainable development?
Climate change can lead to numerous socio-economic impacts, including threats to agriculture, infrastructure, livelihoods, and natural resources.
Provide examples from case studies (Yemen and Malaysia) to illustrate challenges of sustainable development.
Yemen faces challenges like political conflict, poverty, and inadequate access to essential services. Malaysia grapples with biodiversity loss, deforestation, and rapid economic growth at the expense of the environment.
