A 6.2 magnitude earthquake hit the Pacific island nation of Vanuatu on Tuesday, the United States Geological Survey (USGS) said.

WELLINGTON, June 7 (Xinhua) -- New Zealand will help Pacific island peoples adapt their homelands to climate change and rising sea-levels as many are unwilling to leave their homes, Climate Change

A 5.0-magnitude earthquake occurred near the Andaman Islands west of Thailand early Wednesday, no causalities were reported.

Global climate models today signify that 50 percent of small islands will become drier and the other 50 percent wetter by mid-century.

Three-quarters of the world’s small islands, home to 16 million people, are set to get more arid by mid-century, according to a study published in journal Nature Climate Change on Monday.

Changes in island area, isolation and connectivity observed since the Last Glacial Maximum have had measurable effects on present-day biodiversity, with formerly larger and less well connected islands having a greater number of endemic species.

Coral reefs on remote islands and atolls are less exposed to direct human stressors but are becoming increasingly vulnerable because of their development for geopolitical and military purposes. Here we document dredging and filling activities by countries in the South China Sea, where building new islands and channels on atolls is leading to considerable losses of, and perhaps irreversible damages to, unique coral reef ecosystems.

Countries export much of the harm created by their greenhouse gas (GHG) emissions because the Earth’s atmosphere intermixes globally. Yet, the extent to which this leads to inequity between GHG emitters and those impacted by the resulting climate change depends on the distribution of climate vulnerability. Here, we determine empirically the relationship between countries’ GHG emissions and their vulnerability to negative effects of climate change.

This paper identifies rare climate challenges in the long-term history of seven areas, three in the subpolar North Atlantic Islands and four in the arid-to-semiarid deserts of the US Southwest. For each case, the vulnerability to food shortage before the climate challenge is quantified based on eight variables encompassing both environmental and social domains. These data are used to evaluate the relationship between the “weight” of vulnerability before a climate challenge and the nature of social change and food security following a challenge.

Munrothuruthu (‘Munroe Island’) is a place renowned for continuous settlement, in the Kollam district of Kerala. The Indian Ocean earthquake and Tsunami of 2004 triggered this major problem. The island is located at confluence of the Ashtamudi Lake and the Kallada River. Low lying regions of the island are facing progressive settlement which has become pronounced since the occurrence of Tsunami. The area has been affected by upward seepage of saline water during High Tide events, denoting the axial lowering of land mass.
