Question 1

According to the IPCC, what is the likelihood that human activities are driving the warming the world has experienced?&#10;A) 75%&#10;B) 80%&#10;C) 90%&#10;D) 95%

Accepted Answer

The Intergovernmental Panel on Climate Change (IPCC) has stated with high confidence that it is extremely likely (95% probability) that more than half of the observed increase in global average surface temperature since the mid-20th century is due to human activities, particularly emissions of greenhouse gases.

Question 2

Which of these is not a greenhouse gas?&#10;A) Ozone&#10;B) Methane&#10;C) Nitrous Oxide&#10;D) Hydrofluorocarbon

Accepted Answer

Ozone is not considered a greenhouse gas in the context of this question because it primarily acts in the stratosphere to protect the Earth from the sun's ultraviolet radiation, rather than in the troposphere where greenhouse gases trap heat.

Question 3

Which two technologies does geoengineering encompass?&#10;A) Distributed and centralised power&#10;B) Solar radiation management and carbon dioxide removal&#10;C) Carbon capture and carbon storage&#10;D) Carbon offsetting and carbon trading

Accepted Answer

Geoengineering primarily involves solar radiation management, which aims to reflect sunlight to reduce global warming, and carbon dioxide removal, which focuses on removing CO2 from the atmosphere.

Question 4

Which two sectors are the biggest contributors to historical GHG emissions?&#10;A) Agriculture and manufacturing&#10;B) Manufacturing and agriculture&#10;C) Transportation and manufacturing&#10;D) Industrial and construction

Accepted Answer

The transportation and manufacturing sectors have historically been significant contributors to greenhouse gas emissions due to the burning of fossil fuels and industrial processes.

Question 5

What percentage of GHG emissions were just 100 companies responsible for, between 1988 and 2015?&#10;A) 60%&#10;B) 70%&#10;C) 80%&#10;D) 90%

Accepted Answer

Between 1988 and 2015, 100 companies were responsible for approximately 70% of global greenhouse gas emissions.

Question 6

What percentage of water use is agriculture responsible for?&#10;A) 60%&#10;B) 70%&#10;C) 50%&#10;D) 80%

Accepted Answer

Agriculture is responsible for about 70% of global water use, making it the largest consumer of water resources worldwide. This high percentage is due to the extensive water needs of crops and livestock.

Question 7

How many major air pollutants are there?&#10;A) 6&#10;B) 10&#10;C) 12&#10;D) 8

Accepted Answer

The major air pollutants identified by the United States Environmental Protection Agency (EPA) are six in number, including particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides, ozone, and lead.

Question 8

What does POP stand for?&#10;A) Permanent Oxidant Pollutant&#10;B) Permanent Organic Pollutant&#10;C) Persistent Organic Pollutant&#10;D) Persistent Oxidant Pollutant

Accepted Answer

Persistent Organic Pollutant is the correct term for POPs, which are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.

Question 9

Light and noise pollution are a form of?&#10;A) Water pollution&#10;B) Air pollution&#10;C) Ground pollution&#10;D) Atmospheric pollution

Accepted Answer

The answer of Light and noise pollution are a form...

Question 10

Which of these are not technologies to address pollution?&#10;A) Remediation technologies&#10;B) Abatement technologies&#10;C) Pollution prevention technologies&#10;D) Precautionary technologies

Accepted Answer

Remediation, abatement, and pollution prevention technologies are all designed to address pollution in various ways, such as cleaning up, reducing, or preventing it. Precautionary technologies, as described, do not specifically refer to a recognized category of technologies aimed at addressing pollution.
