All Flashcards
Why is the greenhouse effect important?
Keeps Earth warm enough to support life.
What is the impact of increased greenhouse gases?
Leads to enhanced greenhouse effect and climate change.
Explain the relationship between GWP and climate change.
Higher GWP means a greater contribution to warming.
Why is deforestation a concern regarding the greenhouse effect?
Reduces carbon sequestration, increasing atmospheric CO2.
How do human activities enhance the greenhouse effect?
By increasing the concentration of greenhouse gases in the atmosphere.
Explain the difference between natural and enhanced greenhouse effect.
Natural is essential for life; enhanced is due to human activities, causing climate change.
What was the purpose of the Montreal Protocol?
Phased out CFC production to protect the ozone layer.
What is the effect of burning fossil fuels on the greenhouse effect?
Increases CO2 emissions, enhancing the greenhouse effect and causing warming.
What is the effect of deforestation on atmospheric CO2 levels?
Reduces carbon sequestration, leading to higher atmospheric CO2 levels.
What is the effect of increased methane emissions on global warming?
Methane traps heat, contributing to global warming, although its GWP is lower than CFCs.
What are the consequences of increased greenhouse gas concentrations?
Rising sea levels, increased frequency of extreme weather events, and climate change.
What is the impact of agricultural fertilizers on the greenhouse effect?
Increase nitrous oxide emissions, enhancing the greenhouse effect.
