True or False: Wasting less food is a way to reduce greenhouse gas emissions.

Correct! Wrong!

More than a third of food produced globally never makes it to the table. Some of this wasted food spoils in transit, while consumers throw some of this food out. Approximately 8-10% of the world’s greenhouse gas emissions relate to food waste.

Which of the following is a greenhouse gas?

Wideshot of Factory
Correct! Wrong!

Greenhouse gases may be a result of natural occurrence or human activity. These gases include carbon dioxide (CO2), methane (CH4), water vapor, nitrous oxide (N2O) and ozone (O3). Fluorinated gases are also considered to be greenhouse gases. Greenhouse gases act like a heat-trapping blanket, making the Earth habitable for humans. However, human activities have increased emissions of greenhouse gases into the atmosphere beyond what the Earth can support, resulting in climate change.

What is the Greenhouse effect?

Landscape filled with Industries
Correct! Wrong!

The Earth receives solar radiation from the sun. Passing through the atmosphere, some radiation is absorbed by the Earth, while some is reflected back to space. When the exchange of incoming and outgoing radiation occurs, some of the radiation becomes trapped by gases in the atmosphere. This creates a “greenhouse” effect and warms the planet.

Which of the following are consequences associated with climate change?

Correct! Wrong!

All of these are problems associated with climate change. The majority of scientists agree that many of these effects are caused by human contribution to the greenhouse effect. Extreme weather events, droughts, heat waves and rising sea levels are already having devastating effects on the most vulnerable countries and communities.

What can you do to help fight climate change?

Correct! Wrong!

Studies show that 97 percent (or more) of climate scientists who are actively publishing agree that climate change is likely due to human activity. Most of the prominent scientific organizations across the globe have issued statements that publicly endorse this view.

7. What was agreed to in the "Paris Agreement" that came out of COP-21, held in Paris in 2015?

Correct! Wrong!

The Paris Agreement is an international treaty on climate change. It aims to keep the overall increase in global temperatures below 2 degrees Celsius, with the hope of limiting it to 1.5 degrees Celsius. Scientists believe that these are the largest increases in global temperature that we could experience without causing catastrophic change to the Earth’s climate.

Which of these countries emits the most carbon dioxide?

Smoke rising in distance
Correct! Wrong!

China remained the largest single-country contributor to global GHG emissions, with an overall share of 27% of global emissions, followed by the US at 11%, and the EU and India at 7%.

What percentage of the global greenhouse gas emissions does the transportation sector emit?

Large commuting road in City
Correct! Wrong!

Transportation is the fastest growing source of emissions worldwide, and now accounts for 17% of global greenhouse gas emissions - behind only the power sector. Most of this involves fossil fuels burned for road, rail, air and marine transportation. Petroleum-based fuels (i.e., gasoline and diesel) account for almost all of the world’s transportation energy.

Globally, which of the following economic sectors emits the largest percentage of greenhouse gas emissions?

Skyline in polluted sky
Correct! Wrong!

In the electric power sector, which accounts for 28% of overall emissions in the US, emissions decreased by 1% in 2022.

11. Which has been the hottest year on record?

Correct! Wrong!

2020 has effectively tied 2016 as the hottest year on record, with the global average temperature 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean. The last seven years have been the warmest seven years on record.
