Earthquake in 2009 intensified American Samoa’s rising sea levels
The 2009, magnitude-8.1 Samoa earthquake dealt a great deal of damage to the Samoan Islands: Tsunami waves as high as 14 meters (46 feet) wiped out multiple villages, claiming nearly 200 lives and severely damaging water and electrical systems. New research reveals the damage is likely to continue in the island Tutuila, also known as American Samoa.

Early climate action has big effect on rising sea levels
Rising sea levels will accelerate this century and beyond, exposing hundreds of millions of people to flooding and other coastal hazards by the year 2300. But acting early to lower greenhouse gas emissions can slow that rise, say scientists in two new studies in Earth’s Future, an open access journal published by the American Geophysical Union.

Barren marsh reveals plant-loss peril
When the plants go, the whole marsh falls apart. That’s what researchers have found in an innovative experiment in Belgium in which acres of reeds were literally mowed down, enabling the team to observe the consequences of extensive plant loss, which were more severe than expected.
