What is evidence for long-term climate change
mudcores, icecores, tree rings, fossils
What is evidence for short-term climate change
changes in vegetation, animals, glaciers melting, sea level rise
What is the greenhouse effect
Atmospheric gases trap infrared radiation heating up Earth (would be 35C colder without it)
What is the enhanced greenhouse effect
More CO2, methane, etc. makes Earth trap more heat, heating it up too much
What are causes of climate change
sunspots, volcanic eruptions, farming, fossil fuels and deforestation
What are the three Milankovitch Cycles
Obliquity (change in tilt), Eccentricity (change in orbit), Precession (change in wobble of Earth’s axis)
Negative effects of climate change
extreme weather more common and intense, sea levels rise more, indigenous lifestyles irreversibly changed, ecosystems damaged, management is expensive
What is a way to mitigate climate change
alternative energy production, Carbon capture and storage (below ground/water), planting trees
What are ways to adapt to climate change
Raising buildings on stilts/building stronger, change in crops, drip irrigation, diguettes, sea walls, resevoirs, desalination
