- evidence for climate change
- Short term
- satellites
- height of sea, cloud cover, retreating glaciers (photographs)
- radars
- rainfall intensity
- weather boys in the sea
- air and sea-surface temperature
- anomometer
- show the current wind speed
- rain guage
- Untitled
- thermometer
- real time data
- evidence of ice caps melting
- satellites
- Medium term
- historical records
- analyse paintings, photos, grape harvest data
- frost fair on the Thames is evidence for the little ice age
- artistic licence can not dispute the fact the Thames froze over
- frost fair on the Thames is evidence for the little ice age
- analyse paintings, photos, grape harvest data
- tree rings
- retreating or advancing glaciers
- grow and shrink in response to climate
- can measure this through maps, measurements and satellites
- grow and shrink in response to climate
- historical records
- Long term
- ice cores
- co2 levels are sampled from bubbles in extracted air
- low concentration of co2 = cold period
- found in antarctic and greenland have to go down 3,200m 800,000 million years ago
- oxygen isotopes 018/016
- interglacial = o16 evaporated and became enriched with o18
- colder periods = o16
- interglacial = o16 evaporated and became enriched with o18
- co2 levels are sampled from bubbles in extracted air
- rocks
- fossil glacial deposits have been found 280 million years ago in Southern hemosphere
- pollen
- preserved in water logged sediments
- can establish the date and what pollen grew in what climate
- preserved in water logged sediments
- oceans
- thermohaline circulation and sea level change
- ice cores
- Short term
- dendrochronology
- tree rings
