New tipping point discovered beneath the Antarctic ice sheet

A new and worrying way that large ice sheets can melt has been characterized by scientists for the first time. The research focuses on how relatively warm seawater can lap at the underside of ground-based ice, which can accelerate ...

Sea-level rise will have complex consequences: study

Rising sea levels will affect coasts and human societies in complex and unpredictable ways, according to a new study that examined 12,000 years in which a large island became a cluster of smaller ones.

Historical records may underestimate global sea level rise

New research published in Geophysical Research Letters shows that the longest and highest-quality records of historical ocean water levels may underestimate the amount of global average sea level rise that occurred during ...

As Florida Keys flood, property worries seep in

Extreme high tides have turned streets into canal-like swamps in the Florida Keys, with armies of mosquitoes and the stench of stagnating water filling the air, and residents worried rising sea levels will put a damper on ...

Rural areas will bear the brunt of US sea-level rise

It's hotly debated whether coastal wetlands can survive sea-level rise by migrating inland. A new analysis using highly detailed elevation maps of the Chesapeake Bay region shows that—contrary to previous studies—human ...

Alarming projections for polar ice sheets

Drawing on international research, Professor Tim Naish from Victoria University of Wellington's Antarctic Research Centre took the second Pacific Climate Change Conference, co-hosted by Victoria and the Secretariat of the ...

Larger variability in sea level expected as Earth warms

A team of researchers from the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) identified a global tendency for future sea levels to become more variable as oceans warm this century ...
