The use of tree rings, ice cores and glacial activity as evidence of climate change. Layers of accumulation and melting in the ice can reveal the temperature of each year for the past 400,000 years. These seasonal changes affect the nesting and migration patterns of wildlife. Climate change means the air over the oceans can hold more of this moisture, intensifying the storms at sea. Earth history shows climate has regularly responded to cyclical changes in the Sun's energy output. It has a lot to do with predictability. According to scientists studying the ice cores, there is clear evidence of a rapid increase in temperature these past decades.

When snow falls it traps air into the ice. GCSE In the not too recent past the BBC has managed to make a complete hash of their climate change reporting. Can be used to discuss climate change and earth movements (plate tectonics). The degree to which the climate warms in the future will depend on natural climate variability and the level of greenhouse gas emissions.
