Climate Change and Global Warming Quiz

What was the significance of Dr. James Hansen's 1988 testimony?

• It predicted the exact temperature rise for the next century.

• It linked the greenhouse effect to observed global warming with high confidence.

• It was a call to stop all industrial activities immediately.

• It was the first time global warming was mentioned in the U.S. Senate.

What does the GISTEMP record show?

• Fluctuations in Earth's temperature with no clear trend.

• A decrease in Earth's temperature since 1880.

• No significant change in Earth's temperature.

• A clear increase in Earth's temperature since 1880.

Why does the GISTEMP record start in 1880?

• It was the warmest year on record at that time.

• It is the earliest period with reliable global temperature measurements.

• It marks the beginning of the Industrial Revolution.

• It was the year NASA was founded.

How does NASA verify its climate data?

• By comparing it with historical weather predictions.

• By consulting with climate change skeptics.

• Through independent records from other agencies and satellite data.

• By using only ground-based measurements.

What is the primary cause of the current climate change?

• Natural variations in the Sun's activity.

• Human activities releasing carbon dioxide.

• Volcanic eruptions.

• Changes in Earth's orbit.

What role do NASA's supercomputers play in climate research?

• They predict future weather patterns.

• They simulate natural and human climate drivers to identify causes of climate change.

• They are used to store climate data.

• They calculate the exact temperature of every region on Earth.

What is one of the direct indicators of Earth's changing climate?

• The global average temperature.

• The frequency of volcanic eruptions.

• The number of hurricanes each year.

• The amount of rainfall in tropical regions.

How do oceans act as a defense against climate change?

• By absorbing extra trapped energy in the Earth system.

• By increasing the salinity of seawater.

• By absorbing excess carbon dioxide.

• By reflecting sunlight back into space.

What is a consequence of ice melting due to climate change?

• Decrease in global sea levels.

• Increase in freshwater input into polar oceans.

• Reduction in ocean currents.

• Stabilization of global temperatures.

What is the significance of understanding the causes of climate change?

• It allows for the immediate reversal of climate change effects.

• It helps in predicting the exact weather for the next decade.

• It confirms that efforts to reduce emissions would be meaningful.

• It proves that natural factors are the main cause of climate change.
