Answer:
D: They release greenhouse gases
Explanation:
A greenhouse gas (sometimes abbreviated GHG ) is a gas that
absorbs and emits radiant energy within the thermal infrared range.
Greenhouse gases cause the greenhouse effect on planets. The
primary greenhouse gases in Earth's atmosphere are water vapor ( H 2
O ), carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), and
ozone ( O3 ). Without greenhouse gases, the average temperature of
Earth's surface would be about −18 °C (0 °F), rather than the
present average of 15 °C (59 °F). The atmospheres of Venus,
Mars and Titan also contain greenhouse gases.
Human activities since the beginning of the Industrial Revolution
(around 1750) have produced a 45% increase in the atmospheric
concentration of carbon dioxide , from 280 ppm in 1750 to 415 ppm
in 2019.
Greenhouse gases have far-ranging environmental and health
effects . They cause climate change by trapping heat, and they
also contribute to respiratory disease from smog and air pollution.
Extreme weather, food supply disruptions, and increased wildfires
are other effects of climate change caused by greenhouse gases
