Climate Change Trivia Quiz Questions and Answers

What is Climate Change?
A: Climate change is a change in the statistical distribution of weather patterns when that change lasts for decades or longer.

Climate change is caused by factors such as what?
A: Biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.

Certain human activities have also been identified as what?
A: Significant causes of recent climate change, often referred to as "global warming".

Scientists actively work to understand past and future climate by using what?
A: Observations and theoretical models.

More recent data are provided by  what?
A: The instrumental record.

What is the most general definition of climate change?
A: It is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause.

Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, do not what?
A: Represent climate change.


Within scientific journals, global warming refers to surface temperature increases while climate change includes what?
A: Global warming and everything else that increasing greenhouse gas levels will affect.

On the broadest scale, the rate at which energy is received from the sun and the rate at which it is lost to space determine what?
A: The equilibrium temperature and climate of Earth.

This energy is distributed around the globe by  what?
A: Winds, ocean currents, and other mechanisms.

Factors that can shape climate are called what?
A: Climate forcings or "forcing mechanisms".

Some parts of the climate system, such as the oceans and ice caps, respond what?
A: More slowly in reaction to climate forcings, while others respond more quickly.

There are also key threshold factors which when exceeded can produce what?
A: Rapid change.

Forcing mechanisms can be what?
A: Either "internal" or "external".


The climate system can respond abruptly, but the full response to forcing mechanisms might not be fully developed for how long?
A: Centuries or even longer.

Scientists generally define the five components of earth's climate system to include what?
A: The atmosphere, hydrosphere, cryosphere, lithosphere (restricted to the surface soils, rocks, and sediments), and biosphere.

Short-term fluctuations (years to a few decades) such as the El Niño-Southern Oscillation, the Pacific decadal oscillation, the North Atlantic oscillation, and the Arctic oscillation, represent what?
A: Climate variability rather than climate change.

Slight variations in Earth's orbit lead to changes in the what?
A: Seasonal distribution of sunlight reaching the Earth's surface and how it is distributed.

There is very little change to the area-averaged annually averaged sunshine; but there can be strong changes in the what?
A: Geographical and seasonal distribution.

What are the three types of orbital variations?
A: Variations in Earth's eccentricity, changes in the tilt angle of Earth's axis of rotation, and precession of Earth's axis.

Combined together, these produce what?
A: Milankovitch cycles which have a large impact on climate.


The Sun is the predominant source of what?
A: Energy input to the Earth.

Both long- and short-term variations in solar intensity are known to what?
A: Affect global climate.

Three to four billion years ago the sun emitted how much power?
A: Only 70% as much power as it does today.

If the atmospheric composition had been the same as today, liquid water should not have what?
A: Existed on Earth.

The Great Oxygenation Event happened how long ago?
A: Around 2.4 billion years ago.

Solar output also varies on shorter time scales, including the what?
A: The 11-year solar cycle,  and longer-term modulations.

The cyclical nature of the sun's energy output is not yet fully understood, and it differs from what?
A: The very slow change that is happening within the sun as it ages and evolves.

Volcanic eruptions considered to be large enough to affect the Earth's climate on a scale of more than 1 year are the ones that inject how much SO2 into the stratosphere?
A: 0.1 Mt.

This is due to what properties of SO2 and sulfate aerosols?
A: The optical properties.

The eruption of Mount Pinatubo in 1991, the second largest terrestrial eruption of the 20th century, decreased global temperatures by about 0.5 °C (0.9 °F) for how long?
A: Up to three years.

The Mount Tambora eruption in 1815 caused what?
A: The Year Without a Summer.
