Study Finds Human-Caused Sea Level Rise Increased Likelihood of Extreme Coastal Floods
A study published in Nature Climate Change found that coastal floods with a historical 1% annual chance are now about 12 times more likely on average. Researchers attributed the increase primarily to human-driven sea level rise since the 1960s.

Human-driven sea level rise raised extreme coastal flood frequency, study finds
A study published Wednesday in Nature Climate Change found that human-driven sea level rise has made extreme coastal flooding events about 12 times more likely on average since 1900. A second study in Science Advances reported that climate change caused 58 percent of extreme wate…

Thwaites Eastern Ice Shelf Flow Rate Triples Since 2020 Amid Ongoing Changes and Uncertainty
Satellite data show the floating ice shelf in front of Thwaites glacier flowing at more than 2,000 metres per year. Researchers say the shelf has already lost most of its buttressing effect on the glacier.

Paper Projects Sea-Level Rise Threat to Coastal Louisiana
A new study estimates that parts of southern Louisiana could face several meters of sea-level rise by the end of the century. The authors recommend planning for managed retreat from the coast while noting that New Orleans would remain inhabited.

NOAA Maps Show U.S. Cities Facing Flooding Risk from 3-Meter Sea Level Rise
National Oceanic and Atmospheric Administration maps project flooding in multiple U.S. coastal cities if sea levels rise three meters. The projections are linked to potential long-term changes involving the Thwaites Glacier in Antarctica.

Satellite Data Show Sea Level Rise Rate Increased Around 2012
Satellite measurements indicate the rate of global sea level rise increased from 2.9 mm per year before 2012 to 4.1 mm per year since then. Researchers link the change to faster ice melt, reduced land water storage, and lower aerosol pollution.

Thwaites Glacier Eastern Ice Shelf Shows Signs of Detaching
Satellite observations indicate the Thwaites Eastern Ice Shelf is fracturing and accelerating. Researchers report changes in flow speed and structure that reduce its buttressing effect on the glacier.

New Jersey Adopts Coastal Building Rules to Address Sea Level Rise
New Jersey implemented updated coastal construction standards in January that require new homes and major renovations to be built four feet higher than current federal flood standards. The rules also establish inundation risk zones and updated stormwater and wetland protections.…

Scientists Drill Through Antarctic Glacier to Study Ocean Cavity Below
A team of 10 spent eight weeks drilling 3,000 feet through a melting Antarctic glacier to reach the ocean cavity beneath it. The effort aims to gather data on warm currents eroding the ice from below. Researchers hope the information will help clarify the glacier's potential cont…

Study Identifies Mechanisms Behind Antarctic Sea Ice Decline Since 2015
A University of Southampton-led study published in Science Advances traces how strengthening winds, deep ocean heat and a feedback loop drove massive Antarctic sea ice losses equivalent to nearly the size of Greenland. Lead author Aditya Narayanan described a progression from slo…

Studies Reveal Underestimated Sea Levels and Faster Coastal Subsidence
New research indicates that current sea levels are higher than previously estimated in many areas, putting more people at risk of flooding. A separate study shows that subsidence in major river deltas is occurring faster than sea level rise in some cases. These findings suggest i…

Rising Sea Levels Linked to Increased Salt in Drinking Water and Higher Blood Pressure Risks
A recent analysis indicates that rising sea levels may contaminate drinking water with salt in coastal areas, leading to higher blood pressure among residents. The study found that people consuming saltier water had elevated systolic and diastolic blood pressure and a 26% higher…

Researchers Identify 37 Subglacial Lakes in Canada's Arctic, 35 Previously Unknown
A study has identified 37 subglacial lakes beneath glaciers in Canada's Arctic, with 35 discovered for the first time. The lakes form an interconnected network that influences glacier movement and ice loss. This finding uses high-resolution imagery to track surface elevation chan…
