The first effects of climate change are being felt by those people dependent on the oceans for their livelihoods (and the insurance industry). Oyster fisheries have hit upon a temporary measure to respond to ocean acidification.

As the earth keeps warming, many geoengineering solutions are being put forward, such as dropping iron in the ocean or desalinating massive quantities of seawater. A recent study looked at one idea – grinding up olivine and dumping it into the sea – and found it would be extremely inefficient.
June 8th is World Oceans Day, the UN-designated day for the global community to celebrate and take action for our shared ocean. This year, take a moment to make change on two little-known but all-important issues: global warming and ocean acidification.
Human activity is not only causing increased carbon dioxide (CO2) emissions in our atmosphere, but our oceans are suffering as well. CO2 absorption causes the water to become more acidic, which in turn alters marine life’s natural instincts to avoid predation. Researchers fear the results will have “far-reaching consequences for the sustainability of fish populations”. […]
A study by the University of Exeter has provided the first ever evidence that coral reefs can recover from climate change. The researchers surveyed ten sites located within the Bahamas, both inside and out of marine sanctuaries. These reefs, which were studied over a two and half year period, had been severely damaged by bleaching […]
This article was originally published by our friends at Twilight Earth, Adam Shake writes thoughtfully about how our way of life is impacting our oceans. I think weâ€™ve got to be simply dense, or maybe just in denial, to think that the combined actions of our population of 6 billion people doesnâ€™t have any impact […]
Scientists found two unexpected effects of climate changes in the worldâ€™s oceans this week: the Southern Ocean is absorbing less carbon dioxide than expected, while fish raised in water with higher carbon dioxide levels are growing larger ear bones. Scientists have long known that climate change would effect ocean ecosystems, but neither of these effects […]
Can carbon dioxide be stored beneath the bed of our oceans? Apparently so. The UK and Norway commissioned a study of the role of the North Sea in providing storage space deep under the sea for carbon dioxide from European countries.
By 2050, our planet’s oceans could be too acidic for corals to reproduce or rebuild, and the $16 trillion ocean-based economy is in danger of being wiped out if things continue as they are. The high levels of CO2 emitted into the atmosphere from human activities have a dramatic impact on many of our oceans’ […]
A world without fish? Though it might seem like a left-field concept to some, it’s important that we don’t forget that dinosaurs, dodos and other creatures that once roamed freely about our lands have long since died out. Top scientists now warn that our seas face a similar catastrophe thanks to a rise in ocean […]
