climate indicators

Climate indicators are measurements that help us understand changes in the Earth's climate over time. They include temperature records, which show how average temperatures are rising or falling; greenhouse gas levels, like CO₂ concentrations, indicating human impact; sea levels, reflecting melting ice and expanding oceans; and ocean temperatures and acidity, revealing how the climate affects marine environments. Together, these indicators provide a comprehensive picture of climate change, helping scientists track trends, assess risks, and inform policy decisions to mitigate impacts and adapt to a changing climate.
