Correct option is B
The correct answer is option (b) Volcanism is not considered as a cause of climate change.
Volcanism is indeed considered a cause of climate change. Large volcanic eruptions can release significant amounts of ash and sulfur dioxide into the atmosphere, which can have a cooling effect on the Earth's climate. This occurs because the ash and sulfur compounds reflect sunlight, leading to a temporary decrease in global temperatures, a phenomenon known as "volcanic winter."
Information Booster:-
- Changes in solar output, particularly associated with sunspot activity, can influence the Earth's climate. Periods of high sunspot activity may correlate with slightly warmer periods, and low sunspot activity (such as during the Maunder Minimum) has been linked to cooler periods, although solar radiation is only one of many factors influencing climate change.
- Concentration of greenhouse gases in the atmosphere is a major cause of global warming: The increasing concentration of greenhouse gases (such as carbon dioxide, methane, and nitrous oxide) in the atmosphere is a major driver of global warming. These gases trap heat from the sun and prevent it from escaping back into space, resulting in an increase in the Earth's average temperature, known as the "greenhouse effect."
- The annual average near-surface air temperature of the world is approximately 14°C: The global average near-surface air temperature is indeed approximately 14°C (57.2°F). This value is an average of temperatures across all regions of the Earth, considering both land and ocean temperatures.
