• What is some evidence for climate change?

• What is some evidence for climate change?

  Ocean sediment - Layers of sediment that has built up over time. It has provided scientific evidence for climate change as trapped oxygen isotopes have been found.
• What is some evidence for climate change?

  Ice cores - Made up from different layers that each represents a different historical time. E.g water molecules of the ice cores
• What is some evidence for climate change?

  Historical records - Ancient cave painting, diaries and written observations have provide evidence of climate change through personal accounts from the people through them.
