Last year was the hottest year on record for the earth's oceans, according to a new report.
A team of international scientists found that 2018's ocean temperatures beat the previous year's record-setting temperatures, continuing a recent ocean warming trend. Global record keeping started in 1958.
The study's authors say ocean heating is solid proof of climate change, and that the findings are a "major concern" for both the scientific and global communities.
It's the same group of researchers that published a report last week showing that the world's oceans are heating up faster than previously thought.
Warmer oceans can cause issues like rising sea levels, heavier rainfall, stronger storms and melting polar ice.
In November, a government report laid out some of the projected impacts that climate change will have if the U.S. doesn't change its environmental policies. The report warned about risks to human health, the economy, infrastructure and more.
