Imagine losing coastlines, entire islands, and substantial parts of Asia, northern Europe and the Arctic from erosion, floods, and glacial melting. Imagine the consequences of a year with record heat temperatures.
Can you envision a world constantly hit with hurricanes and tsunamis, afflicted with drowning seals and disappearing polar bears, and impoverished by lost marine environments and arctic livelihoods? Can you further envision the disappearance of coral reefs, and depletion of as much as 1/3 of the species in the oceans due to ocean acidification and climate change?
Now, imagine a world where you could make a difference. Imagine that you could help the world better undersand the oceans, reduce ocean pollution, restore ecosystems, repair damaged marine environments and replenish the oceans' resources.
Can you imagine rebuilding the world's oceans and seas, valuable resources upon which so much of our existence depends? Can you imagine taking on challenges such as climate change impacts, ocean acidification, and bleaching of coral reefs?
As one of our most precious assets, the ocean is indispensable to life itself. It is the largest habitat for living things in our solar system and sustains our lives with over 50 percent of the earth's oxygen. "Without our oceans, we wouldn't be able to breathe; we wouldn't be able to eat; we wouldn't be able to live.'"
The Ocean and coastal resources supply us with:
A vital source of food - The ocean is the primary source of protein for over 2.6 billion people worldwide;
A source of employment and livelihood - Economic activity resulting from the ocean indirectly and directly support 200 - 400 million people each year;
Energy that powers the planet - The oceans hold existing and potential oil and gas reserves for future energy use;
A place for leisure and sports - More than 200 million people visit coastal cities and countries each year;
A place to live - Over half of the world's population live within 200 km of a coastline.
Increasing economic activity and climate change, however, have put our marine environments, and our own existence in great peril. Marine ecosystems are at risk of being lost forever; fisheries are facing declining catches; and island states are threatened by rising sea levels. The specter of global terrorism and nuclear activity in the oceans also pose a great danger to our lives.

Dakuwaqa's Garden - Underwater footage from Fiji & TongaLast Updated on 2013-12-03 11:23:34Underwater footage shot whilst scuba diving in the Fiji islands and Tonga. Featuring colorful coral reefs, huge schools of tropical fish, sharks, humpback whales, underwater caves, scuba divers and much more marine life from the south Pacific.

The coral reefs of the south Pacific are alive with a huge variety of tropical fish and marine critters. A great way to explore them is to scuba dive with the Nai'a liveaboard based in Fiji. I was working as the Nai'a's video pro when I shot this footage. See http://www.naia.com.fj/

Pacific Ocean warming faster than it has in 10,000 years, study findsLast Updated on 2013-11-05 07:00:32By Tony Barboza
Los Angeles Times
LOS ANGELES — Scientists have struggled to explain a recent slowdown in the rise of global surface temperatures while skeptics have seized on the 15-year lull to cast doubt on the science of climate change.
A new study offers one explanation of where much of the heat trapped by greenhouse gas emissions is going: the ocean.
Scientists found that parts of the Pacific Ocean are absorbing heat faster than they have over the past 10,000 years. The results, published this past week in the journal Science, suggest seawater is capturing far more energy than previously thought, for now sparing land-dwellers some of the worst effects of climate change.
The ocean’s heat content, which has been measured since the 1960s, accounts for about 90 percent of the earth’s warming, the study says, making it a more reliable indicator of climate change... More »
Ocean Warming Faster Now Than in 10,000 YearsLast Updated on 2013-11-02 10:48:37Pacific Ocean waters warmed 15 times faster in the last six decades than they did over the last ten millennia.
Published October 31, 2013
The ocean depths may store more heat from global warming than suspected, suggests a 10,000-year record of past ocean temperatures measured in Indonesian seafloor cores.
At the same time, since 1950 Pacific Ocean waters have been warming at a rate 15 times faster than the rest of the seafloor, as reported in the journal Science.
"Under normal, natural conditions the oceans are a buffer for temperature changes in the atmosphere," says study lead author Yair Rosenthal of Rutgers University in New Jersey. "But right now, we are completely out of equilibrium." (See "What is Global Warming?")

Plastics Contaminating Lakes, GloballyLast Updated on 2013-10-18 21:57:37
Toxic plastic pollution is filling up the Great Lakes, the European lakes and even the subalpine lakes in Europe's famed Alps. This insidious byproduct of petroleum has infiltrated marine food webs and humans are indeed in harms way.
It wasn't until World War II that polyethylene (plastic single-use disposable bags, dispensable bottles), propylene (bottle caps, fishing gear) and polystyrene (take-away food containers) were invented, and by the late 1960s being mass-produced. By 1979, the production of plastics in the U.S. eclipsed that of steel. Today, globally, humans produce 280 million metric tons of plastic annually.
Plastics are long chains of monomer hydrocarbon molecules, and one of the principle ingredients of all plastics is crude oil. How much? Four percent of the entire world supply, or about 3.4 million barrels of oil, are used to make them each day.

Ocean Deteriorating More Rapidly Than ThoughtLast Updated on 2013-10-15 18:06:24By Alex Kirby, Climate News Network
LONDON – Marine scientists say the state of the world’s oceans is deteriorating more rapidly than anyone had realized, and is worse than that described in last month’s U.N. climate report from the Intergovernmental Panel on Climate Change.
They say the rate, speed and impacts of ocean change are greater, faster and more imminent than previously thought – and they expect summertime Arctic sea ice cover will have disappeared in around 25 years.
Their review, produced by the International Program on the State of the Ocean (IPSO) and the International Union for the Conservation of Nature (IUCN) and published in the journal Marine Pollution Bulletin, agrees with the IPCC that the oceans are absorbing much of the warming caused by carbon dioxide and other greenhouse gases.
But it says the impact of this warming, when combined... More »
