Climate Change Quiz

What is the simplest way to describe climate?

• Average humidity and air pressure

• State of the atmosphere at a particular place

• Average temperature and precipitation over time

• Average wind speed and cloud cover

What is the primary driver of the climate changes observed in the industrial era?

• Changes in ocean currents

• Natural causes like volcanic eruptions

• Emissions of heat-trapping greenhouse gases

• Deforestation

Which of the following is a natural cause of climate change related to the Earth's orbit?

• Solar output variations

• Shifts and wobbles in the Earth's orbit

• Volcanic eruptions

• Deforestation

What is the primary source of human-generated emissions of greenhouse gases?

• Coal mining

• Air pollution

• Burning of fossil fuels like coal, oil, and gas

• Deforestation

What is the main concern related to air pollution and climate change?

• All of the above

• Increase in natural ozone levels

• Presence of particles in the atmosphere that block sunlight

• Ability of pollutants to trap too much heat in the atmosphere

What is the primary greenhouse gas emitted in smaller quantities but traps heat far more effectively than CO2?

• Chlorofluorocarbons

• Nitrous oxide

• Methane

• Carbon Dioxide

What is the European Space Agency's initiative to provide satellite-based climate data records?

• Climate Change Monitoring Project

• Earth Observation System

• Global Change Research Program

• Climate Change Initiative (CCI)

Why do we measure climate change?

• All of the above

• To understand how climate change affects social systems

• To understand climate variability

• To better plan adaptation measures

What are Essential Climate Variables (ECVs)?

• Variables that critically contribute to the characterisation of the Earth's climate

• Variables that are not affordable to generate and archive data

• Variables that are not critical for characterizing the Earth's climate

• Variables that are not technically feasible to observe on a global scale

How is climate change measured over time?

• Using only ocean buoys

• Using only remote meteorological stations

• Using only Earth-orbiting satellites

• Using a combination of Earth-orbiting satellites, remote meteorological stations, and ocean buoys
