The best description of global warming is: It is the increase in Earth’s average surface temperature due to human activity.
The best description of global warming is: "It is the increase in Earth’s average surface temperature due to human activity." However, to understand and reach this answer, it is important to consider the other options as well.
To determine the best answer, one must understand the concept of global warming and how it relates to climate change. Global warming refers to the long-term increase in Earth's average surface temperature. It is primarily caused by the additional greenhouse gases, such as carbon dioxide, being released into the atmosphere from human activities.
Option 1, "It is the day-to-day changes in temperature, precipitation, wind, and humidity," describes weather variability, which is different from global warming. Weather refers to short-term conditions that can vary on a daily basis, while global warming refers to long-term changes in climate patterns.
Option 3, "It is the trapping of heat energy due to the addition of carbon dioxide in the atmosphere," accurately explains the mechanism behind global warming. The increased levels of carbon dioxide and other greenhouse gases in the atmosphere trap heat energy, leading to a rise in Earth's surface temperature over time.
Option 4, "It is the changes to Earth's climate due to increased temperature," is a broader statement that encompasses the effects of global warming. The increased temperature caused by global warming contributes to various changes in climate patterns, such as melting glaciers, rising sea levels, and more frequent extreme weather events.
Therefore, while options 3 and 4 capture essential aspects of global warming, option 2, "It is the increase in Earth’s average surface temperature due to human activity," is the most precise and concise description.

Which of the following are effects of climate change?(1 point)
Responses
changes in the growing season

a decrease in severe storms
These are the effects of climate change. Climate change can disrupt the timing and duration of seasons, including the growing season for plants. It also has the potential to alter weather patterns and lead to changes in the frequency and intensity of severe storms. However, it is important to note that climate change can result in both increasing and decreasing temperatures depending on the region and specific circumstances. Furthermore, climate change can also contribute to more frequent and severe floods and droughts in certain regions.
