Question
Which of the following statements is true?
a)Since nitrogen represents about 78% of the gases in the atmosphere, it is responsible for most of the greenhouse effect for the earth.
b)During 2014, the average temperature across global land and ocean surfaces was 1.24 oF above the 20th century average. This proves that climate change is real.
c)The Greenhouse effect on the moon is larger than it is on earth.
d)In order to be a greenhouse gas, a molecule must absorb infrared radiation at wavelengths greater than 20,000 nm.
e)The amount of solar radiation reflected into space from the surface is less than what is reflected from clouds and aerosols.
f)Current carbon dioxide levels are double what they were 150 years ago.
g)The average global surface temperature rose by about 0.7 oC in the last 100 years.
h)Recovery of the stratospheric ozone layer could accelerate global warming.
i)Transportation is the largest contributor to greenhouse gas emissions in the U.S.
j)The Kyoto Protocol requires all Parties to reduce Greenhouse Gas emissions by the same amount.
k)The Kyoto Protocol did not require China to reduce its Greenhouse Gas emissions.
l)The Kyoto Protocol is currently in effect for the Parties who have ratified it.
m)The Framework Convention on Climate Change, adopted at Rio, imposed mandatory cuts in Greenhouse Gas emissions upon Parties to the Convention.
n)Under the Framework Convention, industrialized countries are listed in Annex I and developing countries are listed in Annex II.
o)Reduction of greenhouse gas emissions is the only way a country can reach its goals under the Kyoto Protocol.
p)Although not an official Party to the Kyoto Protocol, the U.S. is nonetheless meeting the goals to which it agreed during negotiations.
q)Per capita greenhouse gas emissions in China now exceed those in the U.S.
r)A limit of no more than 2 oC above pre-industrial temperatures is the target limit of the Copenhagen Agreement.
2.The Kyoto Protocol made 1990 the baseline year for calculating emission reductions. Why did this represent a problem for former Soviet bloc countries? What provisions did the Kyoto Protocol make for them?
3.How does agriculture contribute to climate change?
4.Which of the following statements is true according the IPCC?
a)The current concentration of atmospheric carbon dioxide is about 400 ppm, which has never been exceeded in the last 400,000 years according to ice core data.
b)If the carbon dioxide concentration increases to about 500 ppm, the global average surface temperature is projected to rise by about 4 oC above pre-industrial levels.
c)A temperature increase of about 1.8 oC would be associated with a sea level rise of about 0.18 – 0.38 meters.
d)The extent of Arctic sea ice has been decreasing in the last 30 years, but Antarctic ice has been increasing.
5.List and briefly discuss five specific consequences of climate change.
