New NASA Study Finds Dramatic Acceleration in Sea Level Rise

nasa-earth-marbles-poster
According to new research, global sea level isn't rising steadily — it's getting faster every year. The findings, which came from an analysis of 25 years' worth of satellite data, are bad news for all low-lying regions threatened by the encroaching ocean : It may rise twice as high by 2100 as previously estimated.  The study, published on Feb. 12 in the journal Proceedings of the National Academy of Sciences, concluded that in the next 80 years, the sea level may rise by up to 26 inches (65 centimeters) as a result of climate change, cutting much larger chunks from the coastal areas than previously estimated.

Ocean Plastic Projected to Triple Within Seven Years

plastic-beach
If we don't act now, plastic pollution in the world's oceans is projected to increase three-fold within seven years, according to a startling new report . The Future of the Sea report, released Wednesday for the UK government, found that human beings across the globe produce more than 300 million metric tons of plastic per year. Unfortunately, a lot of that material ends up in our waters, with the total amount of plastic debris in the sea predicted to increase from 50 million metric tons in 2015 to 150 million metric tons by 2025. Roughly 70 percent of all marine litter is plastic, and the effect of this non-biodegradable waste can be devastating for marine biodiversity . "There is extensive evidence that entanglement in, or ingestion of, plastics can cause injury and death to a wide range of marine organisms, including commercially important fish and shellfish," the report says. The...

The Ocean Has Released an Insane Amount of CO2, And No One Even Noticed

seagrass-01_1024
Our planet's climate is built on a whole host of interlinked chemical reactions and counter-reactions, and we just learned about another: an underwater heatwave has triggered a worryingly huge release of CO2 from Amphibolis antarctica seagrass off north-western Australia.   Vast tracts of these flowering marine plants were killed by the stress of living in waters that were 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) warmer than normal back in the summer of 2010-2011, researchers have found. More than a third of the seagrass meadows were potentially affected. And no one really noticed. And the findings have very real implications for the kind of self-perpetuating heat rises we could be in for, say the international team of researchers, as too much carbon dioxide in the atmosphere warms the planet and leads to the release of even more greenhouse gases. (Paul Lavery) Losing seagrass is a double whammy for our environment's health...

The great Pacific garbage patch is even trashier than we thought

Plastic is everywhere, from our homes and everyday lives all the way up to the illusorily pristine Arctic. The oceans are no exception—our high seas are accumulating plastic just as fast as we can push it out into the world . In a new paper in Scientific Reports, researchers found that the infamous great Pacific garbage patch contains 16 times more plastic than previous estimates showed, and it seems to be increasing over time. The great Pacific garbage patch is one of six areas of the ocean known to accumulate plastic, located in the north Pacific Ocean. While there is a lot of plastic there, the debris aren’t clumped together like some floating landfill. Instead, the plastics (many of them broken down into teeny tiny pieces) are distributed widely across an area of about 617,000 square miles. This particular study didn’t just trawl the zone with screens to measure the...

As some of you might know, since more than 10 years I contribute my skills, knowledge and experience to several Non Profit projects aimed at bettering our Oceans and the professionals roaming them. Notably: 1. DIVE PROFESSIONALS - THEDIVEPROFESSIONAL: 2007 - Present This project is aimed at uniting professional divers worldwide. A network of 30,000 + professionals and growing daily. More information: www.dive-professionals.org 2. GOBLU3 - THE OC3AN CLUB - OASF: Aimed at recreating a lost bond with the Oceans for the wider consumer. Where education, exploration and conservation go hand in hand. www.oceanroamers.biz Most investments and supporting work are done by myself, including the financing and maintaining of the websites supporting these projects. But here's the springing point, I need your help in continuing my work. As we go off the drawing table and live with some projects. Requiring special tools and now also again major updates to our websites...requires $ So thanks for reading my message and contemplating supporting my work by donating to my PayPal​ account for the benefit of the Oceans and Professional Divers worldwide.

#Plastic is one of the most enduring materials we make; it takes an estimated 500 to 1,000 years for it to #degrade, but 50 percent of the plastic we produce is used once and then thrown away. Eight million tons of plastic ends up in the #ocean every year. #oceandebris #plasticpollution #sustainability #goblu3 Facts like this are plentiful, but you get the idea. So, a call to arms. Here are some very easy things to give up in order to curb your contribution to the problem.
