Climate Change Has Caused Five Pacific Islands to Vanish

Five of the Solomon Islands have vanished due to rising sea levels. The effects of climate change will be keeping cartographers busy as our borders continue to shift.

Climate Change Has Caused Five Pacific Islands to Vanish

Climate change will be keeping cartographers busy for the next few decades as the outlines of our continents continue to shift and change due to rising sea levels. But many island nations and cities will be wiped off the map, entirely, as the waters swallow these communities. 

A group Australian researchers are tallying the damage done in the Solomon Islands in a study published in Environmental Research Letters. Five of these islands in the Pacific have already vanished. Over the past two decades the islands have seen the rising sea levels push up their shores seven millimetres each year.

"At least eleven islands across the northern Solomon Islands have either totally disappeared over recent decades or are currently experiencing severe erosion," the researchers reported in their study. "Shoreline recession at two sites has destroyed villages that have existed since at least 1935, leading to community relocations."

Thankfully, the five islands were not populated, but used as occasional fishing spots by local inhabitants. The Solomon Islands have been considered a hotspot for sea level rise by these researchers; the islands have seen shoreline loss three times higher than the global average. The researchers reason the slow loss of these islands are influenced by their exposure to “high wave energy,” which has pushed up shorelines.

“Understanding these local factors that increase the susceptibility of islands to coastal erosion is critical to guide adaptation responses for these remote Pacific communities,” the study said. 

It's possible the next refugee crisis will be not those fleeing from a war-torn country, but from a home-world that no longer exists. The changes have already forced communities to relocate within the Solomon Islands.

“In Mararo village on eastern Malaita relocation as a result of coastal erosion has been more orderly with the entire community making the decision to relocate from the coast to a high elevation site 20 m above sea level,” the study said. "In addition to these village relocations, Taro, the capital of Choiseul Province is set to become the first provincial capital globally to relocate residents and services due to the threat of sea-level rise.” 

NOAA indicates the rate of sea level rise is at 0.12-inches per year. While the Solomon Islands have proven to be a special case, there are more cities under threat of being swallowed by the sea. I was recently in Venice, and watched as the tide came in and the ground beneath me began to bubble with sea water. By the end of it, the whole of Saint Mark's Square was under a few inches of water.

Other parts of Venice resembled beach-fronts, as waves would creep up the stone streets.

Miami is experiencing a similar “nuisance flooding.” Elizabeth Kolbert' piece The Siege of Miami tells a story of of how this city is experiencing a daily high-water maker which continues to moved up about an inch each year.

There should be no doubts that our world is changing. The question is what are we going to do about it?

  • Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
  • That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
  • We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.

  • The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
  • Historians, however, have long debated the deciding factor in the British victory and German defeat.
  • A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.

  • A Japanese radio astronomy project revealed Earth is 2,000 light years closer to the supermassive black hole at the Milky Way's center.
  • The data also showed the planet is moving 7 km/s or 16,000 mph faster in orbit around the Galactic Center.
  • The findings don't mean Earth is in more danger from the black hole but reflect better modeling of the galaxy.
