What do we know about Climate Change? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\



ANSWERS ✔✔1. Climate change impacts will vary by
|\ |\ |\ |\ |\ |\ |\ |\



region
2. Climate change already appears to be causing an
|\ |\ |\ |\ |\ |\ |\ |\ |\



increase in extreme events |\ |\ |\




3. The ocean is becoming more acidic
|\ |\ |\ |\ |\ |\




4. Sea level is rising
|\ |\ |\ |\




Where are species' ranges shifting towards due to climate
|\ |\ |\ |\ |\ |\ |\ |\



change? - CORRECT ANSWERS ✔✔The poles and higher
|\ |\ |\ |\ |\ |\ |\ |\ |\



elevation


Seasonal Timing - CORRECT ANSWERS ✔✔migration and
|\ |\ |\ |\ |\ |\ |\



feeding


What is true about seasonal timing? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\



✔✔it is shifting
|\ |\ |\




What causes ocean acidification? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔The absorption of roughly 1/4 of the CO2 that is in the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



atmosphere into the ocean. |\ |\ |\

,Why is ocean acidification harmful? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\



✔✔It dissolves calcium carbonate, which makes up the
|\ |\ |\ |\ |\ |\ |\ |\



shells of many marine organisms such as corals, clams,
|\ |\ |\ |\ |\ |\ |\ |\ |\



oysters, crabs, and mussels. Could potentially destroy
|\ |\ |\ |\ |\ |\ |\



major commercial fisheries
|\ |\




What climate change impacts are harmful to coral reefs: -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔the warming of water causes |\ |\ |\ |\ |\ |\ |\



coral bleaching and strong storms are physically
|\ |\ |\ |\ |\ |\ |\



damaging


Phenology - CORRECT ANSWERS ✔✔The study of cyclic |\ |\ |\ |\ |\ |\ |\ |\



and seasonal natural phenomena (e.g. on what date does
|\ |\ |\ |\ |\ |\ |\ |\ |\



a plant usually begin to form flowers or leaves?)
|\ |\ |\ |\ |\ |\ |\ |\ |\




*Changing due to climate change (plants are leaving |\ |\ |\ |\ |\ |\ |\ |\



earlier, insects hatching earlier, birds migrating earlier,
|\ |\ |\ |\ |\ |\ |\



animals breeding earlier) |\ |\




Why is hard to assess the impacts of climate change? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



CORRECT ANSWERS ✔✔Because many things are |\ |\ |\ |\ |\ |\



changing at once |\ |\




Polar amplification (arctic intensification) - CORRECT
|\ |\ |\ |\ |\ |\



ANSWERS ✔✔Changes in radiative forcing tend to have |\ |\ |\ |\ |\ |\ |\ |\



greater expression (e.g. increased warming) in polar
|\ |\ |\ |\ |\ |\ |\



regions; the poles will warm faster than the equatorial
|\ |\ |\ |\ |\ |\ |\ |\ |\



regions.
Page |\2 |\of |\50

,What causes polar amplification - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔1. Decreased snow and ice cover that decrease the
|\ |\ |\ |\ |\ |\ |\ |\ |\



albedo in polar regions |\ |\ |\




2. Increased cloud cover that traps heat
|\ |\ |\ |\ |\ |\




3. Increased transport of heat (by ocean currents and
|\ |\ |\ |\ |\ |\ |\ |\ |\



atmospheric circulation) to the poles |\ |\ |\ |\




Where is some of the most rapid warming on the planet
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



experienced? - CORRECT ANSWERS ✔✔In the Western |\ |\ |\ |\ |\ |\ |\



Antarctic Peninsula |\




Climate Change Impacts on Society: - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔1. Ocean acidification could destroy major commercial
|\ |\ |\ |\ |\ |\ |\



fisheries
|\




2. droughts and flooding are leading to agricultural losses
|\ |\ |\ |\ |\ |\ |\ |\




3. Sea level rise will displace people and cause escalating
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



expense
4. More intense storms are causing more property
|\ |\ |\ |\ |\ |\ |\ |\



damage and loss of life |\ |\ |\ |\




5. Farmers and foresters are struggling with altered
|\ |\ |\ |\ |\ |\ |\ |\



growing seasons and disturbance regimes
|\ |\ |\ |\ |\




6.Crop yields will likely fall in the dry tropics and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



subtropics

, Climate Change Impacts on Society pt. 2: - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\



ANSWERS ✔✔1. Impacts on biodiversity will cause losses
|\ |\ |\ |\ |\ |\ |\ |\



of food, water, and ecosystem goods and services
|\ |\ |\ |\ |\ |\ |\




2. Melting of mountain glaciers will reduce water supplies
|\ |\ |\ |\ |\ |\ |\ |\ |\



to millions
|\




3. Economic costs will far outweigh benefits.
|\ |\ |\ |\ |\ |\




4. Poorer nations and communities are suffering greater
|\ |\ |\ |\ |\ |\ |\ |\



impacts
5. Increased warm-weather health hazards will outweigh
|\ |\ |\ |\ |\ |\ |\



decreased cold-weather hazards |\ |\




How much of the world's population lives in regions that
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



depend on mountain meltwater? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔1/6th


Causes of Sea Level Rise - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\



✔✔1.Thermal Expansion (warm water is less dense than |\ |\ |\ |\ |\ |\ |\ |\



cold water) |\




2.Glacier Melt (adds water from continent interiors)
|\ |\ |\ |\ |\ |\ |\




3.Greenland and Antarctic ice sheets (exacerbated by
|\ |\ |\ |\ |\ |\ |\



Arctic intensification)
|\ |\




4.Groundwater extraction (we are rapidly pumping water |\ |\ |\ |\ |\ |\ |\



out of the aquifers)
|\ |\ |\
