How Global Warming and Sea Levels are Interconnected as show above In this NASA video segment, find out how global warming and rising sea levels are interconnected. Learn how the satellite, Jason 2, is able to send radar waves to Earths oceans to determine the height of the sea level. Based on this information, NASA is able to figure out the change of Earths climates, such as global warming.

The two major causes of global sea level rise are thermal expansion caused by the warming of the oceans (since water expands as it warms) and the loss of land-based ice.  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.

Therefore, people may become displaced and will need to seek safer homes. Even life farther inland is threatened because rising seas can contaminate the soil and water that comes from the ground with salt. “Climate change” and “global warming” are often used interchangeably but have distinct meanings. Similarly, the terms “weather” and “climate” are sometimes confused, though they refer to events with broadly different spatial- and timescales.
