Which of these is the best description of the concept of a carbon footprint?

A calculation of the amount of carbon that is directly or indirectly released into the atmosphere by the actions of a specific entity.

What do most scientists think is the best shot our species has for reducing the long-term impacts of climate change on our planet?

Advances in technological solutions paired with alternative energy and changes in personal choices will provide the best chance.

Which of these describes a way that new technologies may be used to lessen the impact of climate change?

Carbon dioxide removal technologies seek to lower the current level of carbon dioxide in the atmosphere.

Which of these describes a way that new technologies may be used to lessen the impact of climate change?

Clean energy technology is aimed at preventing future contributions to greenhouse gas emissions.

What sort of factors are commonly contributed to an individual's carbon footprint?

How often and in what amounts they consume resources.

Which of these foods produces the lowest carbon emissions?

Locally grown fruit and vegetables

Select the parts of the process involved in sourcing nuclear energy.

Power a turbine Create pressurized water Split the nucleus of an atom using uranium Create boiling water

Select the factors that contribute to an individual's carbon footprint.

Sources of electricity Fuel for vehicles Food choices Choices in waste disposal

Where does nuclear energy come from?

Splitting the nucleus of an atom

What are the consequences of rising temperatures on plants and animals used for agriculture?

The consequences are potentially great: raising plants and animals with too much or too little water or heat makes farming challenging and sometimes impossible.

Select ways plants can be genetically engineered to address climate change.

They can be engineered to increase their carbon dioxide consumption.

Select ways that animals can be genetically engineered to address climate change.

They can be genetically engineered to require less water and withstand temperature extremes.

Select all of the values you require to describe the concept of a carbon footprint.

Tonnes of carbon emissions directly released into the atmosphere. Tonnes of carbon emissions indirectly released into the atmosphere.

"Clean" energy and renewable energy are different ways of saying _______________ energy, which is energy from sources like solar, geothermal, and wind.

alternative

The sources of _______________ energy, which is sometimes called "clean" energy, include solar, wind, and geothermal energy.

alternative

The sources of ________________ energy, which is sometimes called "clean" energy, include solar, wind, and geothermal energy.

alternative

In terms of an individual, a measure of their impact on the climate, calculated based on the amount of carbon emitted because of their choices for energy, food, transportation, and other factors, is called a ____________________.

carbon footprint

A calculation of the amount of carbon released into the atmosphere by a specific entity is called a(n)

carbon footprint.

Most scientists think that a combination of advances in technological solutions, alternative energy, and changes in personal choices represent the best chances for our species to reduce the long-term impacts of _________________ on our planet.

climate change

Traditional, nonrenewable energy sources.

coal Oil Natural gas

Energy sources, like fossil fuels and solar energy, each release

different amounts of carbon into the atmosphere.

All food choices contribute ______ to carbon emissions than others: fruits and vegetables contribute comparatively less than ______.

differently red meat and dairy

Implementing technology to address climate change faces challenging like __, especially for large-scale projects like space-focused solar reflection technology.

funding

Place the modes of transportation in order depending on how much carbon they emit into the atmosphere. Place the source that releases the most at the top and work your way down to the least.

gas and diesel powered cars and trucks, airplanes carpool and public transportation hybrid and electric cars

Select the methods that aim to address existing consequences of climate change.

genetic engineering of animals genetic engineering of plants geoengineering

Implementing "climate safe" technology like alternative energy sources can be expensive, which often presents a challenge because

individuals and corporations don't want to adapt to expensive changes.

Select all of the alternative energy sources.

rising temperatures and extreme weather events like droughts and floods.

Alternative, renewable energy sources.

solar Wind Geothermal

Which of these methods aims to prevent future climate change?

using alternative energy sources
