How Acidification, Overfishing and Plastics Threaten the Worlds Oceans
2014-06-04 01:39:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: June 8 is World Oceans Day. Its a fitting time to contemplate humanitys evolving relationship with the source of all life. For much of human history, weve affected marine ecosystems primarily by what weve taken out of the seas. The challenge as we encounter warming temperatures and increasing industrial activity will be to manage what we put into them. As a top predator, humans from the tropics to the poles have harvested all forms of marine life, from the smallest shrimp to the largest whales,...

How oceans can solve our freshwater crisis
2014-05-27 14:39:10| Climate Ark Climate Change & Global Warming Newsfeed
CNN: It's been a cruel irony for ancient mariners and any thirsty person who has ever gazed upon a sparkling blue ocean: Water, water everywhere, and not a drop to drink. But imagine a coastal city of the future, say in 2035. Along with basic infrastructure such as a port, roads, sewer lines and an electrical grid, it's increasingly likely this city by the sea will contain a newer feature. A desalination plant. Thanks to improved technology, turning ocean water into freshwater is becoming more economically...

Climate-changed oceans will mess with life above and below water
2014-05-20 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: If the average temperature of a large body of water increases, thats an enormous amount of heat content, says Andrew Rosenberg, one of the convening lead authors of the National Climate Assessments Oceans chapter. Seas are becoming warmer and more acidic as they absorb atmospheric heat and CO2, which broadly affects ocean circulation, chemistry, ecosystems, and marine life; ocean acidification is already starting to dissolve the shells of small marine organisms. Rising sea surface temperatures...

Daily Mail: Jellyfish blooms around the world are on the rise. Recent warm weather and global warming have both been linked with an increase in sightings as well reports of giant jellyfish reaching the shores in the UK. To accurately plot this upsurge, a team of international researchers has created the Jellyfish Database Initiative, or JeDI, to track locations and predict the future spread. The Jellyfish Database Initiative, or JeDI, pictured, plots the location of jellyfish globally. It is the first...

Can Marine Life Adapt to Worlds Acidifying Oceans?
2014-05-14 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: As the worlds oceans grow more acidic from increased absorption of atmospheric carbon dioxide, marine scientists are confronting a key question: How well can organisms like mollusks, crustaceans, and corals adapt to these more corrosive conditions? One of the leading authorities in this field is University of California, Santa Barbara marine biologist Gretchen Hofmann. Her work in recent years has shown, in fact, that some sea organisms that build shells do seem to have some ability to acclimate...
