historical records, tree rings, retreating glaciers
evidence of short term climate change
weather records, polar ice melt, ecosystem changes
difficulties of predicting climate change
don’t no how emissions will change
unsure how much will be absorbed,
extent of cc due to natural causes is unknown
don’t no how successful attempts to manage cc will be
examples of climate change mitigation strategies
carbon tax, renewable energy, conservation
examples of cc adaptation strategies
water conservation, sea defences, recycle
