But something else also causes sea level to rise. Water expands as it gets warmer. As the temperature of the ocean goes up, the ocean actually expands, even without adding any water from the melting ice!

Cause:
When global temperatures go up, ice trapped on land begins to melt so sea levels rise. Also, as the temperature of the ocean goes up, the ocean actually gets higher because water expands as it gets warmer.

Sea level rise is an increase in the level of the world’s oceans due to the effects of global warming. Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere. The oceans then absorb the majority of this heat. As water becomes warmer, it expands. This results in ocean levels rising worldwide.

# data[].attributes.body
There are two main causes of sea level rise and both are due to heat. Glaciers and ice sheets are large masses of ice that sit on the land. As our planet warms, this ice melts and flows into the oceans. More water in the oceans makes sea level higher.

Sea level is the average height of the ocean. The height of the ocean isn't always the same, it depends on the tides. This is why we use the word 'average' which means typical or normal.

Mountains and countries are almost always above sea level. Sea level rising is when the average height of the ocean gets higher.
What causes sea levels to rise?
Sea levels have naturally risen and fallen for billions of years, but they've never risen this quickly before!

With all our cars and technology, us humans have been contaminating the Earth and releasing lots of carbon dioxide into the air. This has been making the temperature of the Earth higher. The warming up of the planet is called global warming.

When the temperature is higher, more ice on the planet melts and falls into the ocean, making the sea levels rise. Mountain glaciers naturally melt every summer but snow from winter normally balances this out. Recently, more ice has been melting in summer and less snow has been falling in winter.

Millions of years ago the Earth was covered in ice in a time known as the Ice Age. All that's left from the Ice Age are the giant ice sheets in Antarctica and Greenland. Ice sheets act like a mirror, reflecting sunlight and cooling the Earth. If these ice sheets melt, Earth becomes warmer and sea levels go up.

Did you know that water actually expands when it gets warmer? So even without adding any water from melted ice, the ocean will expand if its temperature rises.

The Earth is made up of giant pieces of rock called tectonic plates that slot together like pieces of a jigsaw puzzle. These plates move a tiny bit every year and when they slide past each other they can push the land up under the water. If land underwater rises, then all the water sitting on top of it will rise too.

Quick fact: The oceans absorb more than 90% of the atmospheric heat caused by humans.

The global average sea level has risen over 7 inches in the past 100 years. A few inches may not seem like much, but every inch of sea level rise covers 50-100 inches of beach. If the ice keeps melting, global sea level could rise more than 20 feet.

Rising sea level is one of the clearest signs of global warming. It's also one of the biggest problems that global warming is causing.

What causes sea level to rise?

There are two main causes of sea level rise and both are due to heat. Glaciers and ice sheets are large masses of ice that sit on the land. As our planet warms, this ice melts and flows into the oceans. More water in the oceans makes sea level higher.

Secondly, water expands as it gets warmer. So, warm water takes up more room in our oceans - making sea levels higher.

These two things combined have raised sea level about 7 to 8 inches (about 16 to 21 centimeters) since 1900. That's a big problem for the millions of people who live in communities near the coast.

How do we know sea level is rising?

Unfortunately, you can't just put a long ruler into the ocean to measure sea level rise. Sea level varies from place to place. This is because of differences in geography, gravity, temperature, ocean currents and tides.

Oceans cover about 70 percent of the world. So, to know how much sea level is rising all over planet, you'd have to have millions of rulers in millions of different places.

It turns out the best way to measure changes in sea level is from space.

NASA's Jason-3 satellite carries an instrument called a radar altimeter. It uses radio waves instead of a ruler to measure distances.

Here's how it works. Jason-3 bounces radio waves off the ocean surface. The satellite then times how long it takes for these signals to return. Scientists can use this measurement to calculate the distance between the satellite and the ocean surface in that particular location.

Jason-3 orbits about 800 miles (1,300 kilometers) above Earth. Even from that far away, Jason-3 can measure the distance from itself to the ocean surface to within about one inch (about three centimeters).

Jason-3 also has instruments that allow scientists to measure the distance from the satellite to the center of Earth.

By subtracting the first distance (between the satellite and ocean surface) from the second distance (between the satellite and Earth's center), we can calculate the distance from the ocean surface to Earth's center.

The satellite constantly zips over new portions of the planet. In about 10 days, it measures ocean height over the entire Earth. Finding an average of all those measurements gives an average sea level for the whole planet.

During the next 10 days, Jason-3 does it all over again - and again and again, year after year! By seeing how the average distance from the top of the ocean to the center of the Earth increases over time, we can measure how much and how quickly sea level is rising.

If nothing is done to stop rising sea levels, the homes of 200 million people could be underwater by the year 2100. That's according to a study published in October in the scientific magazine Nature Communications.

The global sea level has been rising for more than a century, and more quickly over the last several decades. That's because climate change is melting glaciers and ice sheets. Higher sea levels flood coastlines. If steps aren't taken to protect cities and towns, people could be forced to move inland.

Water Problems

In the region that is now the Netherlands, people have been inventing ways to keep out water for at least 900 years. "Taking care of water is taking care of ourselves," says Henk Ovink. He works on water issues for the Dutch government.

The country is famous for its dikes, which are long walls that prevent flooding. But in recent years, experts there have developed new techniques that go far beyond dikes. Some are high-tech. For example, the Maeslantkering is a massive storm-surge barrier that protects the city of Rotterdam from seawater. It's controlled by a supercomputer. It closes automatically when Rotterdam is threatened by floods.

NACHO CALONGE-GETTY IMAGES

Other projects look to nature for inspiration. The DakAkker is a farm located on top of an office building in Rotterdam. The building's roof holds rainwater to prevent runoff. Another example is the Floating Farm. Its designers wanted to make room for agriculture in a waterlogged city. More than 30 dairy cows live on the farm, which floats in Rotterdam's waterways. The farm generates its own energy using floating solar panels.

Ovink often advises other countries on how to solve their water problems. "It's not that our solutions are the best," Ovink says. "But your country's solutions can be inspired by us and by nature."

Solution:
We could build dikes (long walls that prevent flooding) or new techniques like the high-tech massive storm-surge barrier in the Netherlands.
