Lab Assignment
Oceans: Warming & Sea Level Rise
Q1: Why does the ocean absorb more of the incoming solar radiation than land surfaces? (2 reasons)
Q2: The balloon did not pop, how might this provide a demonstration of the thermal inertia of the ocean?
Q3: How much of the additional heat caused by the anthropogenic greenhouse effect has been absorbed into the ocean?How much has it raised the ocean's surface temp?
Q4: What impact do warmer ocean temperatures have on coral reefs? What percentage of coral reefs have died due to warming oceans in the last 30 years?
Q5: What percentage of the ocean species are supported by coral reefs?
Q6:What does the IPCC say will happen to coral reefs with a 1.5 deg. C global average temperature rise? With a 2.0 degree C rise?
Q7: Essay Question. What did you know about coral reefs before this class? Consider for a few minutes what is happening to the coral reefs and discuss in depth your thoughts on this. 100-200 words minimum.
Q8: How much as the ocean risen so far? How much is it expected to rise by 2100?
Q9: How much worse could it rise by 2100? What would cause this?
Q10: Work with your group and use Google and find the following two numbers. Confirm you have the right numbers with your Lab Instructor, then follow the series of calculations to find the sea level rise if the entire Greenland Ice Sheet were to melt.
The estimated volume of Greenland ice (km3):___¬¬¬¬¬_____
The area of the Earth's oceans (km2): ________
Use these values to calculate a rough estimate of the number of feet sea level would rise if all the ice on Greenland melted (see equation below) ___________
Greenland Ice Volume (km3) =
Earth's Ocean Area (km2)
Multiply your answer by 0.9167 to account for the expansion coefficient of ice (water will take up less volume than ice, this is why ice floats) _¬¬¬¬¬¬___________
Multiply your answer above by 1.019 to account for the increased density of sea water (salty water takes up more space)__________ _
Multiply this final answer by 3281 ft/km to get your results in feet _______This is the potential sea level rise if the entire Greenland Ice Sheet were to melt.
Q11:What is the potential sea level rise if the entire Antarctic Ice Sheet were to melt?
Q12:How likely is it that the Greenland and Antarctic Ice Sheets will melt by 2100? After 2100?
Q13: Does this website project: 1) when these changes will occur? or2) at what level of CO2 emissions these changes will occur?
Q14: How many US towns and cities do they say are destined to have most of their homes submerged given the current CO2 emitted to the atmosphere?
Q15: How many US towns and cities do they calculate could have most of the homes submerged given:
a)unabated emissions for the rest of this century?
b)drastically cut emissions for the rest of this century?
Q16: The % of Miami's population that will be affected by sea level rise given the current CO2 concentrations:
30%, 50%, 100%
Q17: The % of Miami's population that would be affected by the CO2 concentrations expected by 2100 with unchecked pollution:
30%, 50%, 100%
Q18: The % of Miami's population that would be affected by the CO2 concentrations expected by 2100 with extreme carbon cuts:
30%, 50%, 100%
Q19: Which of the following are NOT included in these images:
Miami FL, Manhattan NY, Portland OR
Q20: Name 6 major coastal cites from around the world that will be impacted due to rising sea levels.
Q21: When does Miami appear to be inhabitable at high tides from the Saving Miami/Jack Black video? Does this seem realistic to you from what you have learned?
Q22: What is the expected sea level rise at the Norfolk Naval Station and what year is this expected to happen by?
Q23: When is the concern about sea level rise the greatest and when can the most damage occur?
Q24: Essay Question. What did you know about sea level rise before this class? Consider for a few minutes what is happening due to sea level rise to shorelines and major cities around the world and discuss in depth your thoughts on this. 100-200 words minimum.
Q25: What is a "climate refugee"?
Q26: What is the difference between a "political refugee" and a "climate refugee"?
Q27: What is "Rights of Asylum" and how does that relate to climate refugees?
Q28: Consider deeply the potential migrations that will be caused by climate change. Discuss how you feel about this, and what you think might be able to be done for this. Know this is a very complex subject, there are no wrong answers, but compassion to all beings is a good fundamental basis to start from. This may well become one of the most challenging subjects in the decades to come. 100-200 words minimum.
