The correct answer is A. More pollution. While pollution can exacerbate environmental issues and contribute to climate change indirectly, it's not typically considered a direct sign of climate change itself. Melting ice caps, desertification, and less potable water are all commonly associated with climate change. Melting ice caps result from rising global temperatures, desertification is caused by changes in climate patterns such as decreased rainfall and increased temperatures, and less potable water can occur due to altered precipitation patterns and increased evaporation rates in certain regions.
