A study led by Rutgers University reveals that current global sea-level rise is occurring at the fastest rate in at least 4,000 years, with an average rise of about 1.5 mm (0.06 inches) per year since 1900, exceeding any century-long period in the past four millennia.
The acceleration is driven by ocean thermal expansion and glacial melt, while coastal delta regions, especially in China, face heightened risk due to subsidence and human activity.
Building on these findings, it’s clear that global warming is rapidly driving sea levels higher, a trend that could wreak havoc around the world as millions of people face the direct impacts of rising water.
Climate Central, the organization that researches the impact of climate change, including sea-level rise and coastal flooding, has created a map that shows which parts of the world could find themselves threatened by rising sea levels. Keep in mind that a lot can change, and ideally governments would finally take serious action to address the climate crisis. However, if they don't, these studies can help us prepare for the potential consequences.
