Throughout Earth’s history, there have been warmer periods and colder
periods. These temperature changes have had significant impacts on the
planet.
Choose the statement below that best describes the difference
between historical temperature changes and current temperature
changes.
Historical temperature changes were abrupt while current changes have been very
gradual.
In the past, temperature change was attributed to changes in the atmosphere, while
today much of it is attributed to the sun’s waning energy output.
Current warming of the planet is occurring faster than any other known temperature
increase.
Current temperatures have been steadily rising for the last 250 years, and, historically,
temperatures both rose and fell.
