Environ Studies 502 Exam #2
large contributors to climate change - ANS-CO2 and greenhouse gases
T or F: climate change can affect air pollution concentrations? - ANS-True
US citizen energy consumption - ANS-6x higher than an average citizen of the world
T or F: the amount of energy the US uses makes the population live longer? - ANS-False
Emissions from fossil fuels - ANS-pollution and Greenhouse gases
True or False: CO2 emissions are lower in spring? - ANS-True- plants suck up the CO2
Human fingerprint - ANS-heating from greenhouse gases are increasing largely due to
effects of climate change - ANS-temperature rise, sea level rise, and more hydrologic extremes
by 2050 the number of "hot" days - ANS-are expected to triple
heat island effect (urban sprawl) - ANS-large urban cities create their own weather
Photochemical smog - ANS-ground level ozone
Thunderstorm asthma - ANS-asthma aggregated by fungi and spores released into the air after
big storms
Biogenic VOCs increase 22-30% per what rise in temp? - ANS-22-30% increase per 1 degree
celsius rise in temp
flooding increases which aeroallergen? - ANS-mold and fungal growth
CO2 fertilization and aeroallergens - ANS-increases pollination of ragweed and poison ivy (also
lengthen pollen season)
Increase temperature and aeroallergens - ANS-increase pollen in the air
2015 Paris Agreement - ANS-21st meeting of the countries with 147 head of states to show up-
agreed on a need for immediate and substantial action
, Co-Benefits of Climate Action - ANS-combat climate change and benefit public health for a net
gain
True or False: indoor and outdoor air pollution can kill? - ANS-True
Asthma and air pollution - ANS-there is a correlation between ground level ozone and
asthma-related doctors visits (ex: when Atlanta hosted the olympics, less traffic made ozone
decrease by 28% and made asthma-related visits decrease by 42%)
Cost of clean air - ANS-<$30/ ton CO2
cost benefit of clean air - ANS-<$200/ton CO2
low-carbon economy - ANS-not only good for environment, but makes air healthier for us to
breathe
how many people around the world use solid fuel in their homes? - ANS-2 billion
particulate matter - ANS-complex mixture of solid and liquid (non-homogeneous- organic
compounds, trace metals, ionic species, water)
PM effects on human welfare - ANS-effects visibility and produces material damage
PM2.5 - ANS-fine particles that are aerodynamic and have the ability to get deep into the lungs
primary particles - ANS-directly emitted into atmosphere that can be seen (smoke from cars,
grills)
secondary particles - ANS-gas-phase chemicals that form condensable products (sulfate and
nitrate)
True or False: climate change is regional as well as global? - ANS-True
clean air and international investment - ANS-attracts investment and tourism
chronic exposure to PM - ANS-create disease and body burden
Human health effects from PM - ANS-respiratory disease, cardiovascular disease, cancer,
auto-immune disease
largest adverse health effects from PM exposure - ANS-heightened blood pressure and
cardiovascular disease
