What is the description of Global climate change?

Question

Options

• AExhaust fumes from daily traffic are contributing to a decrease in air quality that is slowly deteriorating
• BHuman activity is contributing to a buildup of greenhouse gases in Earth's atmosphere that is slowly
• CIT industry waste is contributing to a buildup of CO2 in the Earth's ground that is quickly increasing the

• A
  4% (1)
• B
  92% (24)
• C
  4% (1)

Explanation

Option B is correct because global climate change is defined by the accumulation of greenhouse gases (CO2, methane, etc.) in Earth's atmosphere due to human activities like burning fossil fuels, deforestation, and industrial processes - trapping heat and gradually warming the planet.

Why the distractors are wrong:

• Option A describes localized air quality/pollution from traffic exhaust, which is a regional environmental problem, not the global climate system.
• Option C contains multiple errors: CO2 accumulates in the atmosphere, not the ground, and climate change is a slow/gradual process, not a quick one - plus it wrongly isolates the IT industry as the cause.

Memory tip: Think B = Big picture, Big atmosphere. Global climate change is always about greenhouse gases building up in the atmosphere at a global scale - not localized pollution, not soil contamination, not a single industry.
