alternet.orgPaper 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.
NewsweekNOAA 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.
news.sky.comThwaites Eastern Ice Shelf Shows Signs of Break-Up
Satellite data indicate that the floating ice shelf in front of Thwaites glacier is fracturing. Researchers report that the shelf has lost much of its buttressing effect on the glacier.
ecns.cnSatellite 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.
news.sky.comThwaites 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 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.…
rnz.co.nzScientists 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…
EuronewsStudy 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…
NOAA, a U.S. government agency / Wikimedia (Public domain)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…
thehindu.comRising 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…
Substrate placeholder — needs reviewResearchers 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…
