4.11 Cause/Effect Of Climate Change

Question 1

Sea Ice (Ice “sheets”)

Answer 1

Layers of snow that accumulate (gather) on the surface of waters which do NOT contribute to sea level rise nor melt.

Question 2

Glacial Ice

Answer 2

Ice found at the tops of mountains which DOES contributes to sea level rise when it melts.

Question 3

Thermal Expansion

Answer 3

The increase in the volume of matter when temperature increases, caused by the vibration of molecules. More space in between each molecules happen.

Question 4

Saltwater Intrusion

Answer 4

The invasion of saltwater into freshwater reservoirs, causing harm to trees and biodiversity and leading to freshwater loss.

Question 5

What’s the problem associated with warmer temperatures and sea level rise?

Answer 5

• Saltwater intrusion
• inability of trees and biodiversity to withstand floods of saltwater
• freshwater loss in reservoirs and aquifers.

Question 6

At just a 2 degree Celsius increase in global temperature, what is predicted in terms of sea level rise?

Answer 6

Roughly 1 foot of flooding is predicted, resulting in flooding of areas such as Jamaica Bay, La Guardia, and Staten Island.

Question 7

At a 4 degree Celsius increase in global temperature, what is expected in terms of sea level rise?

Answer 7

6 feet of flooding would be expected.

Question 8

What are the potential EFFECTS of a 2 degree Celsius increase in global temperature in terms of sea level rise?

Answer 8

• Saltwater intrusion
• freshwater loss in reservoirs and aquifers

Question 9

What are the potential effects of warmer temperatures in terms of climate change?

Answer 9

• droughts leading to wildfires
• heavy rain and snow
• extreme weather
• increased evaporation rates

Question 10

What are the change effects of climate change?

Answer 10

• Changes in sea level
• changes in precipitation patterns (extreme weather)
• changes in biodiversity
• changes in human health

Question 11

What is the difference between sea ice and glacial ice?

Answer 11

• Sea ice is layers of snow that accumulate and typically do NOT melt on the surface of waters, does not contribute to sea level rise.
• Glacial ice is found at the tops of mountains and DOES melt which contributes to sea level rise.

Question 12

What are the Anthropogenic causes of Global Warming?

Answer 12

• Changes in greenhouse gas concentration
• Changes in forests
• Changes in agriculture
• Changes in sea ice extent
• Changes in ocean temperatures

Question 13

What do warmer temperatures cause?

Answer 13

• Droughts that can lead to wildfires
• Heavy rain and snow
