Understanding Sea Level Rise and Ice Sheet Instability

What is the primary concern regarding ice sheets in Antarctica and Greenland?

• They are not contributing to sea level rise.

• They are located in the Arctic region.

• They contain 99% of all the freshwater ice on Earth.

• They are melting at a slower rate than expected.

What is Marine Ice Sheet Instability?

• A type of ice sheet found only in Greenland.

• A process where ice sheets stabilize over time.

• A cycle where taller ice leads to more ice loss.

• A method to prevent ice sheets from melting.

According to the IPCC report, what is a 'low likelihood, high impact' possibility?

• Complete stability of ice sheets.

• Sea level rise of almost 2m this century.

• No change in sea levels.

• Immediate reduction in global temperatures.

What are some potential consequences of a one-meter sea level rise?

• Stability of small island states.

• Increased access to freshwater.

• Decrease in global temperatures.

• Devastation of low-lying countries.

What is one proposed method to protect ice sheets from melting?

• Increasing fossil fuel consumption.

• Ignoring the problem.

• Melting the ice sheets faster.

• Building a seabed-anchored curtain.

What is the main goal of targeted geoengineering?

• To increase global temperatures.

• To hold back ice sheets and prevent sea level rise.

• To eliminate all ice sheets.

• To reduce the size of glaciers.

What is a potential drawback of geoengineering solutions?

• They are guaranteed to work without issues.

• They may have unintended consequences.

• They are inexpensive and easy to implement.

• They are universally accepted by scientists.

Why is it challenging to implement geoengineering projects in Antarctica?

• The environment is too warm.

• There are no undercurrents in the area.

• The environment is harsh with strong undercurrents.

• The ice sheets are too small.

What is a potential risk if a geoengineering project fails?

• Sea levels could decrease rapidly.

• Sea levels could rise very fast.

• Global temperatures could drop significantly.

• Ice sheets could become more stable.

What is the primary issue that geoengineering aims to address?

• Reducing sea level rise.

• Burning fossil fuels.

• Increasing global temperatures.

• Stabilizing ice sheets.
