1Climate Change in the Distant PastCycles between glacial and interglacial over the quaternary period
As carbon dioxide levels rise so does the temperature. The glacial - interglacial cycle lasted (approx) 100,00 years
Temps vary by (approx) 10 degrees during the Quaternary Period
2Evidence for Climate Change in the Distant PastFossilized pollen plants no longer in the UK
Fossilized animals no longer in the UK
Samples from ice sheets using carbon dioxide trapped to estimate past temperatures.
Land forms left by glaciers U-Shaped Valley
3Climate Change in the Recent past - The Roman Warm Period (0 to 400 AD)Temperatures during this period rose by 2 degrees. This peaked at around 200AD and began to gradually decline back down to 0 degrees
