Question 1 of 10
What is the greenhouse effect?
The greenhouse effect is the warming of Earth's surface when atmospheric gases trap heat radiated from Earth.
Question 2 of 10
Which gas is the primary contributor to human-caused global warming?
Carbon dioxide from burning fossil fuels is the largest contributor to anthropogenic global warming.
Question 3 of 10
What is the Paris Agreement about?
The Paris Agreement (2015) aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels.
Question 4 of 10
What are ice cores used for?
Ice cores from glaciers contain trapped air bubbles that reveal atmospheric composition thousands of years ago.
Question 5 of 10
What is the difference between weather and climate?
Weather describes short-term atmospheric conditions, while climate refers to average patterns over decades.
Question 6 of 10
What is ocean acidification?
The ocean absorbs about 30% of CO2 emissions, forming carbonic acid and lowering the water's pH.
Question 7 of 10
What is an El Nino event?
El Nino is a climate pattern of unusual warming in the eastern tropical Pacific that disrupts weather worldwide.
Question 8 of 10
What is the albedo effect?
Albedo measures how much sunlight a surface reflects; ice and snow have high albedo, reducing warming.
Question 9 of 10
Which sector produces the most greenhouse gas emissions globally?
Energy production (electricity and heat) is the largest source of greenhouse gas emissions globally at about 25%.
Question 10 of 10
What is permafrost?
Permafrost is ground that remains frozen for at least two consecutive years, found in polar regions and high mountains.
