Which best describes global warming? It is the trapping of heat energy due to the addition of carbon dioxide in the atmosphere, it is the day to day changes in temperature precipitation wind and humidity, it is the changes to earth’s climate due to increased temperature, it is the increase in earth’s average surface temperature due to human activity
It is the changes to earth’s climate due to increased temperature.
The best description of global warming is: it is the increase in Earth's average surface temperature due to human activity.
To understand this, first, let's break down the other options:
1. It is the trapping of heat energy due to the addition of carbon dioxide in the atmosphere: This statement is partially correct. Greenhouse gases like carbon dioxide do contribute to global warming by trapping heat energy in the atmosphere. However, global warming involves more than just carbon dioxide and is not solely caused by it.
2. It is the day-to-day changes in temperature, precipitation, wind, and humidity: This statement describes weather patterns, which are short-term and can vary daily or seasonally. Global warming, on the other hand, refers to long-term changes in the Earth's climate over decades and centuries, rather than day-to-day weather fluctuations.
3. It is the changes to Earth's climate due to increased temperature: This statement is also partially correct. Global warming leads to changes in the Earth's climate, but it does not explain the cause of the increased temperature.
Therefore, the most accurate description is that global warming refers to the increase in Earth's average surface temperature due to human activity. This refers to the long-term trend of rising temperatures that have been observed over the past century, primarily as a result of human activities such as the burning of fossil fuels, deforestation, and industrial processes, which release greenhouse gases into the atmosphere.
