Question 1

Climate change science is an integral part of physical geography and Earth system science.

Accepted Answer

Climate change science is the study of the causes, effects, and potential solutions to the changing climate. It involves a wide range of disciplines, including physical geography and Earth system science, as well as atmospheric science, geology, ecology, and social sciences. Therefore, it is an integral part of physical geography and Earth system science.

Question 2

Paleoclimatologists use direct measurements.

Accepted Answer

Paleoclimatologists study past climates through indirect methods such as analyzing ice cores, tree rings, and sediment layers. They do not use direct measurements of past climate conditions.

Question 3

-According to the RCP8.5 scenario of high emissions

Accepted Answer

The RCP8.5 scenario is a high greenhouse gas emissions pathway that projects significant increases in global surface temperatures throughout the 21st century, potentially reaching up to 4°C by 2100.

Question 4

More-developed countries (MDCs)currently emit the greatest amount of greenhouse gases per capita.

Accepted Answer

MDCs have historically been responsible for the majority of greenhouse gas emissions and continue to have high per capita emissions due to their industrialized economies and high levels of consumption.

Question 5

The physical evidence for global climate change is limited,based primarily on conjecture and indirect evidence.

Accepted Answer

This statement is false. The physical evidence for global climate change is abundant and includes direct measurements of temperature, sea level, and ice cover, as well as changes in vegetation, ocean acidity, and many other indicators.

Question 6

Which of the following is NOT a stated co-benefit of reducing greenhouse gas emissions?

Accepted Answer

Greater dependence on imported oil is not a stated co-benefit of reducing greenhouse gas emissions. In fact, reducing dependence on imported oil is often cited as a co-benefit of moving towards cleaner and more sustainable sources of energy. The other three options (A, B, and C) are all commonly cited co-benefits of reducing greenhouse gas emissions.

Question 7

Many scientists consider climate change to be one of the most critical issues facing humankind in the twenty-first century.

Accepted Answer

Climate change is a widely recognized global issue among scientists, policymakers, and the public due to its potential to cause significant ecological, economic, and social consequences in the coming decades.

Question 8

The rate of population growth decreased after 1950.

Accepted Answer

The answer of The rate of population growth decreased after...

Question 9

Carbon dioxide (CO₂)produced from human activities is amplifying Earthʹs natural greenhouse effect.

Accepted Answer

This is a widely accepted scientific fact. Human activities such as burning fossil fuels and deforestation release large amounts of CO2 into the atmosphere, which traps heat and causes global temperatures to rise.

Question 10

According to models developed by NOAA,by the end of the 21st century,global sea level may rise as high as

Accepted Answer

NOAA models project that global sea levels could rise by as much as 2.0 meters (6.6 feet) by the end of the 21st century, considering high greenhouse gas emission scenarios and potential ice sheet collapse.

Question 11

Which of the following is NOT an example of an action an individual can take to help mitigate against climate change?

Accepted Answer

Improving regional land use practices is typically a collective or policy-driven action rather than an individual action.

Question 12

Which of the following is INCORRECT?

Accepted Answer

While scientific evidence strongly suggests that human activities are the primary cause of climate change, it is difficult to definitively attribute all climate changes to anthropogenic causes alone, as natural climate variability also plays a role.

Question 13

Which of the following is NOT an example of individuals and communities working to mitigate climate change?

Accepted Answer

Leaving the decision-making to elected officials does not actively involve individuals and communities in efforts to mitigate climate change.

Question 14

Which scenario predicts the lowest level of warming during the 21st century?

Accepted Answer

RCP2.6 assumes that ambitious climate policies will be implemented, resulting in a drastic reduction in greenhouse gas emissions. This scenario predicts the lowest level of warming, with a likely range of 1.0-1.8°C by 2100.

Question 15

Climate has fluctuated naturally over Earthʹs long history.As a result,most scientists are skeptical that human activity has contributed to recent trends in global climate.

Accepted Answer

The statement is false. Most scientists agree that human activity, such as the burning of fossil fuels and deforestation, has contributed to recent trends in global climate.

Question 16

An estimated _________people could be displaced by a sea level rise of 1.0 m (3.2 ft).

Accepted Answer

The answer of An estimated _________people could be displaced by...

Question 17

The majority of human population growth is now occurring in more-developed countries (MDCs).

Accepted Answer

The majority of human population growth is actually occurring in less-developed countries (LDCs), while population growth in MDCs tends to be slower or even declining in some cases.

Question 18

According to the U.S.Department of Energy,the U.S.could meet the carbon emission reduction targets in the Kyoto Protocol

Accepted Answer

The U.S. Department of Energy estimates that the U.S. could meet the carbon emission reduction targets in the Kyoto Protocol at a savings of $7 to $34 billion a year.

Question 19

The legally binding international agreement to reduce greenhouse gas emissions is known as the

Accepted Answer

The Kyoto Protocol is a legally binding international agreement, signed in 1997, that aims to reduce greenhouse gas emissions, primarily carbon dioxide, in order to combat climate change.

Question 20

In May 2013,the Mauna Loa Observatory recorded the highest CO 2 concentrations on record.

Accepted Answer

This statement is true. Mauna Loa Observatory in Hawaii recorded a daily average of 400 parts per million (ppm) of carbon dioxide in the atmosphere on May 9, 2013, which was the highest recorded at that time.
