What do we know about Climate Change? - 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? -
ANSWERS--The poles and higher elevation
Seasonal Timing - ANSWERS--migration and feeding
What is true about seasonal timing? - ANSWERS--it is shifting
What causes ocean acidification? - ANSWERS--The absorption of
roughly 1/4 of the CO2 that is in the atmosphere into the ocean.
Why is ocean acidification harmful? - 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: - ANSWERS-
-the warming of water causes coral bleaching and strong storms are
physically damaging
Phenology - 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? - ANSWERS--
Because many things are changing at once
Polar amplification (arctic intensification) - 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.
What causes polar amplification - 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? - ANSWERS--In the Western Antarctic Peninsula
Climate Change Impacts on Society: - 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: - 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? - ANSWERS--1/6th
, 4|Page
Causes of Sea Level Rise - 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)
Does melting sea ice lead to sea level rise? - ANSWERS--***NO!**
What does higher sea levels lead to? - ANSWERS--Beach erosion,
coastal flooding, intrusion of saltwater into aquifers, and greater
impacts from storm surges
Storm Surges - ANSWERS--temporary and localized rise in sea level
due to a storm--responsible for most damage during hurricanes
How can global warming be beneficial to agriculture? - ANSWERS--
For some crops in temperate zones, warming may lead to longer
seasons and better yield, and added CO2 may increase the yield of
some plants
How can global warming be harmful to agriculture? - ANSWERS--
Added CO2 can make plants become less nutritious and increased
drought and flooding may decrease agricultural productivity
