- Global warming
- Not caused by human activity
- Carbon dioxide increase may be due to release from warming seas
- Temperature rise may be natural / cyclical
- Carbon dioxide from volcanoes / forest fires
- Temperature rise may link to solar activity
- Caused by human activity
- Carbon dioxide produced by combustion of fossil fuels
- Deforestation
- CFCs from land fills
- Global temperature rise over last century linked to rise in carbon dioxide levels
- Increased number of cars
- Evidence of occurence
- Ice cap loss (and satellite images showing this)
- Rise in sea level
- Recent rise in global temperature
- Changes in species range
- Temperature data from meteorological surveys
- Fossil / glacial data
- Effects
- Coral bleaching
- Loss of zooxanthellae
- Ocean acidification
- Ice caps melting
- Sea level rise
- Change in salinity
- Sea level rise
- Water oxygen depletion
- Increased phytoplanktonic productivity
- Loss of species / food sources
- Coral bleaching
- Not caused by human activity
