by the Guardian, researchers used computer models to analyze how ocean water intruding into ice sheet cavities impacted melting rates. They believe this could create a “tipping point” where the sheets lose ice much faster than expected.

by the National Oceanic and Atmospheric Administration project large swaths of the West and East Coasts will eventually succumb to the oceans, but the latest analysis suggests the tipping point could be closer than initially believed.

Almost 40% of the global population lives less than 65 miles from a coast, according to the

According to

, the 10 hottest years on record have all occurred in the past decade, with 2023 being the warmest ever recorded. These warmer temperatures are causing ice sheets to melt and ocean water to expand, thus contributing to rising sea levels.

The higher water levels also increase the risk of costly damage and deadly flooding during extreme weather events. Strong hurricanes, for example, have become more frequent as a result of our changing climate, with rapid intensification a growing phenomenon.

What can be done about rising sea levels?

Floating homes and land reclamation projects are among the initiatives providing hope that we can adapt to rising sea levels. However, Dr. Bradley also called for bold action to help preserve our coastal communities.

“With every tenth of a degree of ocean warming, we get closer and closer to passing this tipping point…” Dr. Bradley

The global community still has a ways to go to reduce its reliance on ****** fuels and meet its agreed-upon pollution-reduction goals, but there have been promising developments. For example, in 2023, clean energy accounted for a record 30% of electricity worldwide, with wind and solar installations leading the way, according to
