____ warming has been progressing much faster than scientists originally predicted, and warming temperatures are causing sea levels to rise at a faster rate than ever recorded around the world.

For example, scientists predict that the ____ island nation of Kiribati will have disappeared under rising sea levels by the end of this century.

This is a problem not just for the ____ Pacific countries.

Coastal and low-lying areas ____ are at risk of disappearing from the world map before the 21st century ends.

Global warming is causing global sea levels to rise in ____ ways.

The first factor is the melting of land ice — ____ and ice sheets.

The enormous bodies of ice ____ huge land areas like Greenland and Antarctica, and they hold large amounts of fresh water.

As they melt, the water flows ____ the ocean.

This causes sea levels to ____.

The second factor is the expansion of ____.

When water gets warmer, it naturally expands, and this ____ the water in the oceans.

Since the oceans absorb ____ than 90% of the excess heat trapped by greenhouse gases in the atmosphere, they continuously warm up and accordingly seawater expands.

This increased volume of water occupies more space in the oceans, ____ causes a rise in sea level.

These include building sea walls and better drainage systems to ____ flooding.

Another solution is to raise buildings above flood level or use structures that ____ float on water.

Preserving and protecting wetlands and mangroves can also reduce the risk of flooding since they absorb water ____ heavy rains or storms.

As individuals, we ____ also play a part in dealing with sea level rise by reducing our carbon footprint.

Such efforts ____ include walking, biking, and using public transportation.

Using energy-efficient electronic devices can also be part of such ____.

Supporting organizations that work to protect the ocean environments is another way we ____ make a difference.

Furthermore, many people are still ____ of the risks of sea level rise.

One of the most effective and efficient ____ we can take is to raise awareness about the risks.

By raising awareness, we can help others ____ the fight against global warming.
