NASA launched a new satellite on Saturday to measure sea level changes with greater precision.
Even though this satellite will be 1,000 miles away, it can measure the height of our oceans to an one inch accuracy.
The "Sentinel-6" satellite will help scientists study how water rises along coasts, with particular focus on regional differences.
As temperatures continue to go on the rise, our oceans warm says Dr. Ben Hamlington, a NASA Climate Scientist. He says that's because oceans absorb a lot of the Earth's heat.
As our oceans warm, their water expands, which leads to more coastal flooding.
Ben says sea level is connected to our climate and weather.
Sea levels rises help scientists spot warmer parts of the ocean. They're particularly interested in these warm spots because warm ocean water is the fuel for hurricanes and tropical storms. The warmer the ocean water gets, the stronger the hurricanes and tropical storms can get.
This satellite's sea level information will also help computer weather models forecast the weather better, both in the short term and long term.
The satellite's sea level information will also help communities on coasts plan for their future.
So, some communities are already planning ahead.
In Louisiana, the federal government has paid people in swampy, coastal communities to move because in the near future, their communities will be underwater.
"Hopefully we can create improved information, improved science [because of this satellite] that we can then give to planners and decision makers so they can improve their plans for the future to help people living along the coast" says Ben.
The "Sentinel-6" satellite launched just after noon on Saturday.
The satellite is at the very tip of the rocket. The rest of the rocket is designed to carry fuel. There's fuel throughout the rocket's "pencil" shape.
