Final answer:
The data from various sources provide evidence for global climate change and can predict future changes in our climate.
Step-by-step explanation:
The data from various sources such as ice cores, tree rings, glacier size, pollen counts, and ocean sediments, along with the study of changes in Earth's orbit and solar activity, provide evidence for global climate change. By analyzing past and current data, scientists can predict future changes in our climate.
For example, declining mountain snowpack and prolonged drought conditions could threaten water supplies, while rising temperatures can lead to longer heatwaves, increased wildfires, and rising sea levels that jeopardize coastal areas. Additionally, a shift from snow to rain can increase the risk of floods and worsen air quality.
