Reducing Ozone Depletion
This agreement caused the world to phase out use of CFCs
What is the Montreal Protocol?
Burning these substances is the largest anthropogenic source of GHGs
What are fossil fuels?
Name a coastal impact of climate change.
What are flooding of low-lying areas, submergence/inundation of former coastline, and loss of barrier islands?
These species out-compete native species
What are invasive species?
This type of species is most at risk from the effects of climate change.
What are specialist species?
CFCs were commonly used for these two purposes
What are refrigerants and propellants?
Data from this source allows scientists to reconstruct climate data from the distant past
What are ice cores?
Name three indicators of global climate change.
Global average temperature increase
Increased temperature extremes - higher highs and lower lows
Increased heat waves and drought
Increased precipitation and flooding
And many more...
This is causing shifts in biomes, habitat ranges, and temperature and precipitation patterns
What is climate change?
Building habitat corridors is a useful tactic to help combat this impact of human activity on the natural world
What is habitat fragmentation?
What are HCFCs?
This GHG has a GWP of 25
What is methane?
In this index, the value of CO2 is defined as 1
What is GWP, or Global Warming Potential?
Excessive hunting and poaching is called this
What is over-exploitation?
Describe the role of producers in the Carbon Cycle, specifically to their impact on atmospheric CO2
Producers use solar energy for photosynthesis, decreasing the amount of carbon dioxide in the atmosphere and increasing the amount of carbon sequestered in plant tissue.
HFCs are different than CFCs because they do not contain this critical substance
What is chlorine?
This is the largest source of American Nitrous Oxide emissions
What is fertilizer?
What are Milankovitch cycles?
This is occurs when larger habitats are broken into smaller, isolated patches
What is habitat fragmentation?
Describe the relationship between oceanic pH and the ability of corals and other sea creatures to create their shells.
What is as oceanic pH decreases, the ability to make shells decreases.
What makes Cl so problematic in depleting Ozone?
It is very persistent - can stay in the atmosphere for 50-100 years. One Cl atom can destroy up to 100,000 O3 molecules!
This natural source of GHGs temporarily cools the planet - name it and explain why it does so
What are volcanoes, which reflect incoming solar radiation when ash and SO2 particles are injected into the stratosphere?
Explain the annual variations in the Keeling Curve.
What are the seasonal changes in global photosynthetic activity? During NH Summer, more plants are active than in NH Winter, resulting in a sawtooth pattern in the CO2 trace that is higher after the NH Winter and lower after the NH Summer.
What does HIPPCO stand for?
What is Habitat Fragmentation, Invasive Species, Population Growth, Pollution, Climate Change, and Over-exploitation
This is the deadliest form of skin cancer associated with depletion of the Ozone layer.
What is melanoma?
