Which of the following is a common indicator of climate change?

Rising global temperatures is a key indicator of climate change as it reflects the cumulative effects of greenhouse gas emissions and changing atmospheric conditions attributed to human activities. The increase in average global temperatures can lead to a variety of environmental impacts, such as melting glaciers, rising sea levels, and shifts in ecosystems and weather patterns. This phenomenon is primarily measured through long-term data collection from weather stations and satellite observations, showing a clear warming trend over the past century.

In contrast, population growth and increased agricultural productivity can occur independently of climate change and do not serve as direct indicators of changing climate conditions. Similarly, reduced energy consumption is often associated with efforts to mitigate climate change rather than serve as a measurable indicator of it. Therefore, the rise in global temperatures provides a crucial and clear metric for understanding and assessing the ongoing effects of climate change.
