Carbon - dioxide is a major greenhouse gas. Its long - lasting presence in the atmosphere allows it to continuously trap heat, contributing to global warming. Option A is incorrect as CO₂ levels are increasing. Option C is wrong as the warming effect is changing with rising CO₂ concentrations. Option D is not the main reason for CO₂ being blamed for global warming.
