Question 1

Which organism is the first species whose extinction was directly related to climate change?

Accepted Answer

The Bramble Cay melomys, also known as the Bramble Cay mosaic-tailed rat, was declared extinct in 2019. This small rodent species was found only on a single low-lying coral island in the Great Barrier Reef and its extinction was directly linked to sea-level rise and increased frequency and intensity of weather events due to climate change.

Question 2

Climate change affect which of the following?

Accepted Answer

Climate change can have widespread impacts on the environment, including changes in weather patterns and sea levels, as well as effects on plant and animal species. It can also impact human health through increased incidence of heat-related illnesses, respiratory problems, and other diseases. Economies can also be impacted by climate change, with changes in agricultural productivity, fishing and forestry industries, and impacts on tourism. Finally, societies can be impacted by climate change, with the potential for increased social and political instability as communities are forced to adapt to changing conditions. Therefore, all of these answers are correct.

Question 3

Changes in global climate are predicted to have a negative impact on forests.Forests provide which of the following ecosystem services?

Accepted Answer

Forests provide all of the ecosystem services listed, including soil stabilization, water purification, carbon storage, and oxygen production. Therefore, all options listed under the answer choices are correct.

Question 5

Accepting climate change as inevitable and adjusting as best as possible is referred to as __________.

Accepted Answer

Adaptation refers to adjusting to the unavoidable impacts of climate change, such as building sea walls to protect from rising sea levels or implementing drought-resistant crops in areas experiencing reduced rainfall. Prescription refers to a medical treatment plan, mitigation refers to reducing greenhouse gas emissions to slow down climate change, and stabilization refers to achieving a stable level of greenhouse gas concentrations in the atmosphere to prevent further warming.

Question 6

Climate change affects ocean ecosystems by _____________.

Accepted Answer

Climate change leads to the increase in carbon dioxide (CO2) which is absorbed by the ocean, causing it to become more acidic. This process is known as ocean acidification, which can harm marine organisms by affecting their ability to form shells and skeletons. This, in turn, can disrupt ocean food webs and alter biogeochemical cycles.

Question 7

How will climate change affect agriculture?

Accepted Answer

Storms and floods can damage crops and wash away soil and nutrients, which can have a negative impact on agriculture. Climate change is predicted to increase the occurrence and severity of extreme weather events like storms and floods, which could lead to increased crop damage and reduced yields.

Answer: None of the above
 While some of the statements may be partially true (e.g. higher CO2 levels can lead to increased productivity), overall, the impacts of climate change on agriculture are likely to be negative. Heat stress and drought can reduce yields, while increases in pests and diseases could harm crops. It is also important to consider the broader impacts of climate change, such as changes in precipitation patterns, sea level rise, and extreme weather events, which could have significant negative effects on food security and agricultural production in many regions.

Question 8

Question 10

What animals can be affected by climate change?

Accepted Answer

All of these animals can be affected by climate change. Sea turtles may be impacted by rising sea levels and changes in temperature that could affect their nesting sites and food sources. Alligators may face increased heat stress and changes in their aquatic habitats. Ringtail possums may be impacted by changes in their forest habitats due to altered rainfall patterns and temperature. And polar bears are perhaps one of the most well-known examples of animals affected by climate change, as melting sea ice takes away their habitat and hunting grounds.

Question 11

Climate models can use programs to make future climate projections by plugging in values for ____________.

Accepted Answer

Climate models consider all of these variables (temperature, CO2 levels, global air circulation patterns, and precipitation) when making future climate projections. By inputting different values for each of these variables, models can simulate how the Earth's climate might change under different scenarios.

Question 12

How will human health be affected by climate change?

Accepted Answer

Climate change increases the range of disease-carrying insects, such as mosquitoes, and also the incidence of diseases like dengue fever and malaria.

Answer: D 
 Climate change can worsen air quality and pollen production, leading to more allergies. Poor plant growth can also limit the production of certain allergens, but this effect is likely to be outweighed by other factors.

None of the other choices are supported by current research on the effects of climate change on human health.

Question 13

Potential effects of climate change likely include all of the following EXCEPT _______.

Accepted Answer

All of the options listed (A through D) are potential effects of climate change. Climate change can lead to more severe droughts, heat extremes, colder winters in some regions due to disrupted weather patterns, and increased fire risk in boreal forests due to drier conditions and higher temperatures.

Question 14

Which of the following statements is FALSE regarding climate models?

Accepted Answer

Climate models that include anthropogenic factors are more accurate because they take into account the human impact on climate change.

Question 15

Further changes in global climate will have a significant effect on world forests.Global climate changes will impact both mean annual ______ and ______,which will cause shifts in tree populations.

Accepted Answer

Climate changes affect temperature and precipitation patterns. Changes in these factors can cause shifts in the population of trees in different regions, as some species are more adapted to certain environmental conditions than others. Therefore, changes in temperature and precipitation will have a significant effect on world forests.

Question 16

Explain how clouds can participate in both positive and negative feedback loops.

Accepted Answer

The answer of Explain how clouds can participate in both...

Question 17

The upper limit on the number of people that will be forced to leave their homes because of climate change is 1 in every ___ people on Earth.

Accepted Answer

The upper limit on the number of people that could be displaced due to climate change is estimated to be 1 in every 50 people on Earth.

Question 18

The cause of the vast majority of climate change can be attributed to ____________.

Accepted Answer

The burning of fossil fuels is the main cause of climate change, as carbon dioxide and other greenhouse gases are released into the atmosphere, trapping heat from the sun and leading to global warming. While other factors such as volcanic activity, agriculture, and forest fires can also contribute to climate change, they are not the primary cause.

Question 19

Describe how the recent changes in global climate are expected to impact biodiversity.

Accepted Answer

The answer of Describe how the recent changes in global...

Question 20

Efforts intended to minimize the extent or impact of climate change are referred to as ___________.

Accepted Answer

The term "mitigation" is commonly used to describe efforts to minimize the extent or impact of climate change, through actions such as reducing greenhouse gas emissions or increasing carbon sequestration. Adaptation refers to actions taken to adjust or cope with the impacts of climate change, while facilitation and stabilization are not commonly used phrases in the context of climate change.
