Lolo Flashcards
What contributes to rising sea levels globally in the Arctic?
The melting of Arctic sea ice and the Greenland ice sheet
This contributes to global sea level rise by adding freshwater to the oceans.
How does thawing permafrost affect greenhouse gas levels?
Thawing permafrost releases significant amounts of CO2 and methane
These gases contribute to further global warming.
What ecological impact does the loss of sea ice have on polar bears?
It affects their ability to hunt, putting them at risk of becoming endangered
Polar bears rely on sea ice for their hunting grounds.
What are the potential socioeconomic impacts of melting sea ice in the Arctic?
New shipping routes may boost trade and benefit local ports
Additionally, natural resource exploitation becomes more accessible.
What is a consequence of melting ice sheets in Greenland?
They contribute to global sea level rise
This can lead to coastal flooding in various regions worldwide.
What global implications arise from disruptions to ocean currents in the Arctic?
They can affect global ocean circulation patterns
This has potential consequences for climate regulation.
True or False: Changes in Arctic temperatures can impact air currents and weather patterns globally.
True
The atmosphere operates as an interconnected system.
Fill in the blank: Addressing the impacts of Arctic warming requires global efforts to reduce _______.
greenhouse gas emissions
Mitigation of climate change is essential for addressing these impacts.
What ecological changes may occur due to shifts in biodiversity in the Arctic?
Some areas may experience an increase while others see a decrease in species diversity
This can lead to imbalances in food chains.
What happens to infrastructure built on permafrost as it thaws?
It becomes unstable and susceptible to damage
Thawing of the ground affects the structural integrity of buildings and roads.
What role does the North Atlantic Drift play in climate regulation?
It helps regulate climate in regions like Europe
Disruptions to this current can have significant climatic effects.
