Which could increase average global temperatures?
increased use of fossil fuels
decrease carbon dioxide emissions
decrease rate of deforestation
increase in wetland acreage
Which two are likely to result from global warming?
increase in surface temperatures
reduction in greenhouse gases
rise in ocean levels
decrease in air pollution
Melting land ice...
causes sea levels to rise because it adds water to the ocean.
does not cause sea levels to rise because the water fills the space left by the melted sea ice.
MAIN greenhouse gas responsible for Climate Change is:
nitrogen
carbon
carbon dioxide
methane
Which of the following have been changed or altered due to climate change ?
droughts
flooding
melting of polar ice caps
all of the above
Which of the following are evidence of climate change?
extreme weather events
increase in the average global temperature
melting of polar ice caps
all of the above
The role of the Intergovernmental Panel on Climate Change is to
implement carbon taxes on companies that burn excessive fossil fuels
collect and analyze scientific climate data like that from ice cores
review scientific climate data to assess the current state of climate change
introduce policies to help with mitigation and adaptation strategies
What do scientist look at inside ice cores?
Trapped bubbles that contain gasses
Dirt
How thick the layers are
How many layers there are
If Earth had no greenhouse effect, it would be ________.
colder
hotter
completely covered with water
the same as it is now
CO2 in our atmosphere is a trace gas; its concentration in the air is 387 parts per million, less than a tenth of one percent. If there were no CO2 in the air at all, Earth's surface would become:
about the same temperature as now
5 or 10 degrees F colder
"snowball earth", more than 60 degrees F colder and covered in ice
When climate doubters argue that global warming isn't happening, one approach they use is to:
show a short time series of just a few years, rather than decades;
show a temperature record that's regional, not global;
focus on anecdotal temperature measurement imperfections to argue that there's a consistent bias
all of the reasons given
Which of the following factors describes the impacts of climate change?
Reducing the impacts will not be expensive.
The effects will be short-term.
Everyone is affected uniformly.
Both the problem and the solution involve politics.
