Climate change is a complex phenomenon affecting Earth's temperature and atmospheric composition, with significant impacts on global ecosystems and human activities.
- The Earth's climate system is experiencing unprecedented warming, with CO2 levels reaching historic highs
- Sources of information about past climate shifts include deep-sea mineral deposits, pollen grains, coral reefs, and polar ice cores
- Impact of human activities on greenhouse gases is evident through fossil fuel combustion, deforestation, and industrial processes
- The difference between climate and weather changes lies in their temporal and spatial scales, with climate representing long-term patterns
- Multiple observable impacts include glacier retreat, permafrost degradation, and changes in wildlife behavior
- Solutions involve both individual and collective actions, from tree planting to reducing fossil fuel consumption
