PHY 105 Module Eight Google Earth Exercise: Climate Change and Sea Level Rise
Part 1: Greenland Ice Melt
Question:
Besides a general increase in the number of melting days the ice sheet is experiencing,
what other patterns do you see? Does the location of the melt stay consistent? Can you come up
with any ideas as to why this may be happening?
-
The melt's location stays consistent, and most of it occurs on the country's northwestern
and southwestern sides. This could be occurring due to the water temperatures and the
current on that side of the country.
Part 2: Climate Change and Food Resources
Question:
What is the potential impact of global climate change on farmers that grow cereal
crops, especially as we enter into the 2080s?
-
This region's capacity to produce cereal crops is decreasing as a result of global warming.
This will prevent this region from producing nearly as many crops as it originally did in
the 2020s.
Questions:
What is the future of growing crops throughout South America as our climate
changes over the next century? Why do you think North-Central South America is going to
change so much?
-
Climate change will make it harder for South America to grow as many crops as it can
now. The Amazon rainforest's disappearance in this region has profoundly impacted
North-Central South America. We often overlook the benefits of the rainforest, such as its
role in storing CO2 and regulating the climate, while we clear it out to make more space
for livestock to graze and grow crops.
Questions:
White means there is no growing potential. Why do you think the white is
expanding? What is happening here as temperatures increase?
-
Desertification is robbing the dry plains regions of Africa of their resources. A part of the
world that is currently experiencing poor soil fertility and a rapidly expanding population
that they are already struggling to feed is being stressed by the people living here and
raising cattle. The desert is expanding, and the arid soil is becoming drier as the
temperature rises.

Part 3: Drought and Water Resources
Question:
Lack of basic necessities of life is one of the biggest causes of conflict around the
world. Based on what you saw in both map scenarios, what is the potential that we will see
growing conflict in the Southern Hemisphere, both in South America and Africa, over the next
few decades? What areas are most at risk?
-
The drought that is now affecting the southern hemisphere has become worse over time
and is expected to continue doing so if nothing is done to reverse it. Due to deforestation,
the central region of South America is vulnerable to drought, as is the northern region of
Africa where desertification is taking place and the desert is expanding every year.
Part 4: Sea Level Trends
Question:
Why would sea level appear to be dropping in Canada, rising slowly in New England,
and rising faster in the Mid-Atlantic? Hint: Think about what you learned about glaciers and how
the landscape may respond after they retreat.
-
Glaciers cut away land as they traveled over the surface of the planet, leaving behind
debris in certain places. Because of this process, various parts of the same shoreline are
experiencing differing amounts of sea level rise.
Question:
Can you think of any reasons why the sea level rise rates would be so high in this
area? Hint: Think about sediment transportation and river systems.
-
The construction of levees in streams to prevent their expansion as a result of seasonal
floods every year has increased the amount of silt that is discharged into the Gulf of
Mexico from rivers. Many tons of silt is washed into the Gulf of Mexico in the spring
when it starts to rain harder, but the levees stop the material from traveling normally.
