Coral reefs are on course to become the first ecosystem that human activity will eliminate entirely from the Earth, a leading United Nations scientist claims. He says this event will occur before the end of the present century, which means that there are children already born who will live to see a world without coral.
The claim is made in a book published tomorrow, which says coral reef ecosystems are very likely to disappear this century in what would be "a new first for mankind – the 'extinction' of an entire ecosystem". Its author, Professor Peter Sale, studied the Great Barrier Reef for 20 years at the University of Sydney. He currently leads a team at the United Nations University Institute for Water, Environment and Health.
The predicted decline is mainly down to climate change and ocean acidification, though local activities such as overfishing, pollution and coastal development have also harmed the reefs. The book, Our Dying Planet, published by University of California Press, contains further alarming predictions, such as the prospect that "we risk having no reefs that resemble those of today in as little as 30 or 40 more years".
Blobs of slimy jellyfish are taking over some beaches in the southern United States, the result of a shrinking fish population caused by humans, scientists claim.
“Now that fish are being overfished in a lot of ecosystems, it's providing an opportunity for jellyfish populations to explode,” said Sean Colin, an associate professor of marine biology at Roger Williams University in Rhode Island.
“There's been evidence suggesting that there are more and more jellyfish blooms globally.”
Even the little jellys sting like a bugger. I went snorkelling in the Carribe a number of years ago. The surface of the water was clear when I went in. After a few breathhold swims below I surfaced, and I was surrounded by dozens of jellyfish. I got the hell out of the water in a hurry.
This list does sound like the grocery list of a 1 percenter who shops only at a Dean & Deluca in Park Slope. (Wine-filled, coffee-flavored, bacon-flecked chocolate is a thing, right? Well NOT FOR LONG.) But the die-off of oysters heralds a serious environmental problem and indicates how quickly the climate is changing. Oysters are dying because of ocean acidification.
But I thought global capitalism was about creating more choices for everyone not fewer?
Pecan pie? Fresh oysters from Nova Scotia? WTF? Next it'll be a dwindling supply of tabasco sauce to drizzle on scarce oysters. I'm not liking this at all.
Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.
The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years.
Methane is not 20 times more potent than CO2 (unless you average it over a period greater than 100 years)... according to the IPCC it's 25 times more potent averaged over 100 years, and 72 times averaged over 20 years, due to the short lifetime of methane in the atmosphere relative to C02. Which is why large scale methane released are so worrisome.
Record floods, melting permafrost, shoreline erosion and intense winds caused havoc for thousands of Quebecers as 2011 proved to be yet another year of higher than normal temperatures.
These higher temperatures add to the credibility of climate models that have predicted the march of global warming will accelerate the more greenhouse gases we pump into the atmosphere, scientists say.
“It is striking that over the last 10 to 15 years we didn’t have a single season colder than normal,” said Alain Bourque, director of climate change impacts and adaptation at Quebec’s climate change research institute Ouranos. “That is a clear indication that Canada’s climate is heating up beyond any reasonable doubt.”
While most Quebecers may cheer the warmer winters, Bourque warns it is already endangering coastlines, the northern communities that are built on permafrost and our forests, which probably will not be able to adapt fast enough to a warmer climate.
He said warmer temperatures for pretty well all seasons indicate Quebec is well on its way to meeting the climate-model predictions that we are fast closing in on the 2C mark many scientists claim is the tipping point that will plunge the globe into catastrophic climate change.

The International Energy Agency projects that, unless societies begin building alternatives to carbon-emitting energy technologies over the next five years, the world is doomed to a warmer climate, harsher weather, droughts, famine, water scarcity, rising sea levels, loss of island nations, and increasing ocean acidification.
Since fossil-fuel burning power plants and infrastructure built in 2012-2020 will produce energy — and emissions — for 40 to 50 years, the actions taken in the next few years will set us on a path that will be impossible to redirect. Even if policy leaders decide in the future to reduce reliance on carbon-emitting technologies, it will be too late.

To say nothing of the military response to dwindling resources.
"The rapidly deteriorating biophysical situation is more than bad enough, but it is barely recognised by a global society infected by the irrational belief that physical economies can grow forever and disregarding the facts that the rich in developed and developing countries get richer and the poor are left behind.
"The perpetual growth myth ... promotes the impossible idea that indiscriminate economic growth is the cure for all the world's problems, while it is actually the disease that is at the root cause of our unsustainable global practices", they say.
The group warns against over-reliance on markets but instead urges politicians to listen and learn from how poor communities all over the world see the problems of energy, water, food and livelihoods as interdependent and integrated as part of a living ecosystem.
"The long-term answer is not a centralised system but a demystified and decentralised system where the management, control and ownership of the technology lie in the hands of the communities themselves and not dependent on paper-qualified professionals from outside the villages," they say....
The answer to addressing the critical issues of poverty and climate change is not primarily technical but social, say the group. "The problems of corruption, wastage of funds, poor technology choices and absent transparency or accountability are social problems for which they are [sic] innovative solutions are emerging from the grassroots."
Greenhouse gases that drive man-made climate change are also dangerously changing ocean chemistry, likely faster than at any other time in the past 300 million years, according to research coordinated between New York state and the United Kingdom.
The change – known as ocean acidification – is associated with several massive extinctions of marine life in that period of Earth's history, and now presents a growing threat...
The work is the first of its kind to survey the geologic record of the oceans for such a vast time period...
Ocean acidification works like this: Burning of fossil fuels like oil, coal and natural gas releases the greenhouse gas carbon dioxide (CO2) into the atmosphere, There, the gas keeps more of the heat from the sun from radiating back into space, a process that an international scientific consensus says is gradually raising the planet's temperature.
At the same time, about a quarter of the increasing CO2 is being absorbed by the oceans, where it is converted into carbonic acid. This is steadily making the ocean more acidic, which among other things can harm the ability of sea creatures to thrive, or make hard shells or skeletons. Rising acidification can also affect marine organisms by causing slower growth, fewer offspring, muscle wastage and dwarfism.
Some scientists have called this gradual process the "evil twin" of climate change.
The study "raises the possibility that we are entering an unknown territory of marine ecosystem change," said Andy Ridgwell, a professor of planetary modeling at the University of Bristol who took part in the study.

I add, at the rate were going so will us humans! (if not beforehand but hey if our species dissappeared than most likely the coral could recover)
