2.

In the event of global warming, food production might be negatively affected by all of the following except

Poorer soil in new crop-growing rotations
Increased insect populations
Lack of irrigation water in some areas
Decreased UV radiation resulting from increased ozone

Correct Answer

A. Decreased UV radiation resulting from increased ozone

Explanation

Global warming can have several negative impacts on food production. Poorer soil in new crop-growing rotations can occur due to increased temperatures and changes in precipitation patterns. Increased insect populations can damage crops and reduce yields. Lack of irrigation water in some areas can result from changes in rainfall patterns and increased evaporation rates. However, increased ozone resulting from global warming can lead to decreased UV radiation, which can actually benefit crops by reducing the risk of damage from excessive UV exposure.

The consequences of rapid climate change over decades might include

Premature deaths from lack of food
Reduction in earth's biodiersity
Social and economic chaos
All of these answers

Correct Answer

A. All of these answers

Explanation

Rapid climate change over decades can lead to various consequences, including premature deaths from lack of food, reduction in Earth's biodiversity, and social and economic chaos. These effects are interconnected and can exacerbate each other. Lack of food due to changing weather patterns and extreme events can result in malnutrition and starvation, leading to premature deaths. Climate change also disrupts ecosystems, causing a decline in biodiversity as species struggle to adapt or face extinction. Additionally, the social and economic impacts of climate change, such as displacement, resource conflicts, and economic instability, can further contribute to chaos and instability. Therefore, all of these answers are correct in describing the consequences of rapid climate change.

A rise in sea level is least likely to

Flood areas where one-third of the world's human population lives
Save the coral reefs
Accelerate coastal erosion
Contaminate coastal aquifers

Correct Answer

A. Save the coral reefs

Explanation

A rise in sea level is least likely to save the coral reefs because coral reefs are highly sensitive to changes in water temperature and salinity. As sea levels rise, the increased water volume can lead to higher water temperatures and increased sedimentation, which can stress and damage the coral reefs. Additionally, the rise in sea level can cause coral bleaching, where the corals expel the symbiotic algae living in their tissues, leading to their death. Therefore, it is unlikely that a rise in sea level would have a positive impact on the survival and preservation of coral reefs.

Which of the following statements about the potential effects of global warming on human health is false?

Food and freshwater supplies are likely to be disrupted
People are likely to be displaced
Insect-borne disease are likely to decrease in today's temperate zones
Sanitation systems in coastal cities may be flooded

Correct Answer

A. Insect-borne disease are likely to decrease in today's temperate zones

Scientists who claim the global climate system is so complex we will never have the level of certainty wanted by decision makers urge

Take no action now because global warming is all hype
Take action now based on the precautionary principle
Take no action until we get more data
Continuing monitoring of the data

Correct Answer

A. Take action now based on the precautionary principle

Explanation

The correct answer is to take action now based on the precautionary principle. This is because scientists believe that the global climate system is complex and uncertain, and waiting for more data may lead to irreversible damage. The precautionary principle suggests that it is better to take preventive action to avoid potential harm, even if the evidence is not conclusive. Therefore, decision makers should not wait for absolute certainty and instead take action to address global warming.

All of the following are prevention approaches to global warming except

Taxing gasoline and carbon dioxide emissions
Shifting to perpetual and renewable energy sources
Improving energy efficiency;transfer energy-efficiency and pollution prevention technologies to developing countries
Dispersing methane from landfills to prevent explosions

Correct Answer

A. Dispersing methane from landfills to prevent explosions

Explanation

The correct answer is "dispersing methane from landfills to prevent explosions." This is because dispersing methane from landfills is not a prevention approach to global warming. While it may prevent explosions, it does not directly address the issue of greenhouse gas emissions and climate change. The other options mentioned, such as taxing gasoline and carbon dioxide emissions, shifting to renewable energy sources, and improving energy efficiency, are all prevention approaches that aim to reduce greenhouse gas emissions and mitigate global warming.

At the 1992 Earth Summit in Rio de Janiero, ____ nations committed themselves to reducing greenhouse gas emission to 1990 levels by the year 2000.

25
50
75
Over 100

Correct Answer

A. Over 100

Explanation

The correct answer is "over 100" because at the 1992 Earth Summit in Rio de Janeiro, more than 100 nations committed themselves to reducing greenhouse gas emissions to 1990 levels by the year 2000. This indicates that the number of nations that made this commitment exceeded 100.

The 1997 Kyoto treaty to reduce global warming would

Not require developing countries to make any cuts in their greenhouse gas emission unless they choose to do so
Allow emissions trading
Allow forested countries to get a break in their quotas
All of these answers

Correct Answer

A. All of these answers

Explanation

The 1997 Kyoto treaty aimed to reduce global warming and had provisions that addressed different aspects. One provision stated that developing countries were not required to make cuts in their greenhouse gas emissions unless they voluntarily chose to do so. Another provision allowed for emissions trading, which means that countries could buy and sell emission allowances to meet their targets. Additionally, forested countries were given the opportunity to receive a break in their quotas as a recognition of their efforts in preserving forests. Therefore, the correct answer is that all of these answers are true.
