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?

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.

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.
