Coal Miners Win From Relaxed Environmental Conditions

Numerous large Australian coal mines have had their environmental regulations relaxed, in changes the federal government hopes will make life easier for the struggling industry.

Environment law is not red tape, it is a safeguard for Australia's clean water, air and good health.
Australian Conservation Foundation spokesman Paul Sinclair

Certain coal mines owned by Glencore, BHP Billiton and Whitehaven Coal have received favourable changes to their approval conditions within the past month, which in some cases reduce the environment minister's ability to demand changes and reduce public oversight of miners' compliance with approval conditions.
The changes, many of which were initiated by the environment department rather than being requested by mining companies, come after a series of controversial coal approvals in recent years and after the federal government threatened to change environment laws in a bid to prevent green groups using the courts to challenge approvals.
Approvals for two Glencore coal mines in the Hunter Valley, Bulga and Liddell, have had environmental conditions revoked within the past month which appear to remove the environment minister's ability to request changes to environmental management plans.
The Caval Ridge coal mine that BHP operates had eight conditions on its approval altered last week, including one which means the company no longer has to wait for written approval from the minister if it wishes to change the way it manages offset areas or threatened species, so long as the companies believe their new plan will not have an increased impact.
Some miners were also told they can report on compliance with their environmental conditions less often, with BHP now allowed to report on Caval Ridge once every two years rather than annually.
The alterations also mean BHP no longer have to publish their compliance reports for Caval Ridge on their websites, and instead need only submit their documents to the environment department.
BHP's Mt Arthur coal mine in the Hunter Valley and the Tarrawonga and Werris Creek coal mines run by Whitehaven have also had their environmental approvals altered.
A spokeswoman for the Federal Environment Department said that some of the recent changes were initiated by the department, and were not specifically requested by the companies involved.
"In line with the Australian government's broader regulation reform agenda, some recent variations have been initiated by the department as a means of reducing unnecessary regulatory burden. These variations are designed to reduce the administrative burden associated with approval conditions while still maintaining high standards of environmental protection," she said.
The spokeswoman said that 34 project approvals had been changed over the past nine months, with the environmental conditions loosened in 21 of those cases.
The spokeswoman said the changes were being made to a range of project approvals, not just coal mines.
But coal mines appear to be very well represented, with Fairfax Media aware of at least seven coal approvals which have been changed in recent months.
Fairfax Media is aware of just one copper mine (BHP's Olympic Dam) and one iron ore mine (run by BC Iron) which have had conditions changed.
Australian Conservation Foundation spokesman Paul Sinclair said it was not appropriate for the government to be running from Australia's environmental law.
"Environment law is not red tape, it is a safeguard for Australia's clean water, air and good health," Dr Sinclair said.
"The Federal Government has a duty to ensure major resources companies comply with the law."
When asked if BHP was happy with the changes, a company spokesperson said; "BHP Billiton welcomes actions by all levels of Government which are directed towards reducing the regulatory and compliance burdens faced by the sector."
The Minerals Council said it did not believe the environment minister's powers had been reduced.
"We believe that regulation and compliance can be more efficient and effective while continuing to uphold high environmental standards," said a spokesman for the council.
"The MCA supports a risk-based approach to compliance, which account for a company's track record and the maturity of their environmental management systems among other things. This reduces unnecessary regulatory burden on the operator and allows regulators to target their compliance resources more effectively.
"Where appropriate, project conditions should focus on the achievement of environmental outcomes and not unnecessary prescription on how those outcomes are achieved. This flexibility allows for adaptive, innovative approaches to be used."

City To Swelter Under Climate Change Predictions

Melburnians should prepare for more extreme heat with double the number of hot days, less rain and harsher fire conditions in coming decades, the state government has been warned.
Analysis prepared for the Andrews government paints a frightening picture of Melbourne's future climate, with transport infrastructure vulnerable to flooding and heat stress, longer and more severe bushfires and pressure on hospitals from heatwaves.
The modelling, from the CSIRO and Bureau of Meteorology, predicts climate change could have a major impact on the state's health system, economy and environment, including shorter snow seasons, food production challenges and problems with transport infrastructure.

The forecasts were prepared as the Andrews government seeks to elevate climate change as a political issue ahead of possible new laws to tackle emissions.
The predictions, based on international climate models, show that under a high emissions scenario similar to the current trend, the number of days over 35 degrees in Melbourne would more than double from an average of eight a year to 17 by 2070. Average rainfall could drop by up to 23 per cent in the most extreme case.
"Despite an overall trend of declining rainfall, more of the rain that does fall will be in increasingly extreme downpours," it said. "This is likely to lead to an increase in the incidence of flooding events, particularly in urbanised and small catchments."
The report says Melbourne has already become warmer and drier in recent decades, with sea levels up about 23 centimetres since 1880.
If the current high emissions trend continues, the report says, Melbourne's temperature could rise by as much as 2.6 degrees above the 1986 to 2005 average by 2070, with sea levels up by as much as half a metre.
"In 2050, under high emissions, the climate of Melbourne will be more like Adelaide now," the report says.
Other scenarios in the report are less dire although even under a lower emissions scenario, average temperatures would still rise by 1.5 per cent by 2070 compared to the 1986 to 2005 average.
Environment Minister Lisa Neville said Victorians were already feeling the effects of a warmer climate. She said the government was working to ensure the "right legislation" was in place to "deliver climate change action".
The economic, environmental and social ramifications of the changes are likely to be significant. The report warns future governments may need to consider moving "selected populations" in areas of extreme heat to other parts of the state. In one scenario Mildura would have 66 hot days a year.
Increased temperatures would have a major effect on Victoria's tourism sector, the projections show.
"The impacts of climate change on tourism are likely to include increased heat waves and harsher fire weather. Significant reductions in stream flows will adversely affect water-based tourism," it says.
The report finds temperatures have increased by up to 1.6 degrees in some parts of Melbourne since 1950.
Victoria's transport network would also be hit under the most extreme forecasts.
"Transport infrastructure will be increasingly exposed to periodic flooding and increased heat loading. Extremely high temperatures may also reduce the performance of the railway network, potentially leading to disruptions."
Warming seas and increased storm surges could also harm coastal ecosystems.
"Loss of biodiversity will place greater stress on the personal and economic wellbeing of communities in Greater Melbourne."
Monash University Cooperative Research Centre for Water Sensitive Cities Professor Nigel Tapper said the latest forecasts appeared consistent with international research.
While increased heat would impact Victorians' health, Dr Tapper said he was optimistic about reducing greenhouse emissions.
He said increasing vegetation in Melbourne could help to cool the city.
"If we do that we can mitigate against some of that extreme heat," he said.
The report also warned more hot days and heatwaves would exacerbate existing health risks, adding to pressure on hospitals and emergency services. "The urban heat island will add to heat stress," it said. "Vulnerable groups may need assistance to manage extreme heat, bushfires and flooding."

The Coal Miner `On Everybody's List' as Next Bankruptcy Victim

Bloomberg & 


Plummeting coal prices have pushed almost half the debt issued by U.S. coal companies into default, and for miners and their investors there’s no end in sight.
Patriot Coal Corp., Walter Energy Inc. and Alpha Natural Resources Inc. have all filed for bankruptcy in the past year. Now that Arch Coal Inc., the second largest coal miner in the U.S., has joined their ranks, investors are wondering if the biggest, Peabody Energy Corp., could be next.
Peabody’s shares have been sliced roughly in half since Arch filed for Chapter 11 on Jan. 11, closing at $3.38 Wednesday. The company’s 6.5 percent unsecured bonds have lost 27 percent, or 3.1 cents on the dollar, over the same period, most recently trading on Jan. 14 at 8.6 cents and yielding 99 percent, according to Trace, the bond-price reporting system of the Financial Industry Regulatory Authority.
“Lots of people are wondering: What’s the next shoe to drop? Who might be the next company? Peabody’s on everybody’s list,” said Spencer Cutter, a Bloomberg Intelligence analyst in Skillman, New Jersey, in a webcast presentation about the global coal industry on Jan. 14.
Coal producers are suffering through a historic rout. Over the past five years, the industry has lost 94 percent of its market value, from $68.6 billion to $4.02 billion.


In addition, Fitch Ratings said in a Jan. 11 report that Arch’s bankruptcy pushed the sector’s default rate to “an unprecedented peak” of 43 percent. So investors are now raising questions about the viability of other miners, such as Consol Energy Inc., Foresight Energy LP, Cloud Peak Energy Inc. and Murray Energy Corp.
“This once mighty industry is destined to gradually shrink in importance, and virtually disappear as an investable sector,” said Margie Patel, a portfolio manager with Wells Fargo Asset Management in Boston, which manages $351 billion.

Big Debt
Peabody and Arch were among the miners that raised a total of $6.4 billion of debt in 2010 and 2011, betting that prices for metallurgical coal, which is sometimes used to produce steel, would continue to rise thanks to China’s growing demand to build its cities. After reaching $330 per metric ton in 2011, prices have since tanked to a quarter of that level. Goldman Sachs Group Inc. forecasts benchmark metallurgical coal prices to fall to $75 this year.
Peabody has been working on a debt exchange with its lenders since last year, but has yet to agree to a deal -- Arch tried a similar tact before it went under and failed, accelerating its demise.
“Could Peabody do a debt exchange? Possibly, but does that really solve the big picture problem?” Mark Levin, an analyst at BB&T Capital Markets in Richmond, Virginia, wrote in a note to clients Wednesday. “The board has to ask itself if it’s better off restructuring.”

Capital Cushion
In terms of capital, Peabody had $1.4 billion in liquidity including cash and availability under its revolving loans as of Nov. 5, according to a company filing. Its cash dropped to $167.4 million on that day from $334.3 million at the end of September. At that rate, the company is going to run out of cash in nine months, Bloomberg data show.
Peabody’s cushion will be pressured with coal prices so low. Its interest expenses are more than its cash on hand, according to Bloomberg data. For the 12 months ended Sept. 30, it burned through $445 million.
“In a challenging market backdrop, Peabody continues its aggressive efforts to
improve the business with a major focus on operational, portfolio and financial
initiatives,” Peabody spokeswoman Beth Sutton said via e-mail. “Our dual financial objectives are to optimize liquidity and deleverage, and we continue to pursue multiple actions on this front.”

Going Bankrupt
If Peabody does file for Chapter 11, it will have plenty of company among its competitors. In less than two years, as many as five coal miners have filed for bankruptcy to restructure a total of $22 billion in debt, according to data compiled by Bloomberg.
James River Coal Co. filed for bankruptcy in April 2014 to restructure its $819 million in debt. Patriot Coal, which emerged from Chapter 11 at the end of 2013, filed again in May. Walter Energy and Alpha Natural, two of the biggest metallurgical coal producers in the U.S., filed in July and August with a combined total of $12.1 billion in debt.
In addition, Cliffs Natural Resources Inc. sold its coal business to Seneca Coal Resources for $268 million in December. Lourenco Goncalves, Cliffs’ chief executive officer, explained in a statement that the sale was made “in light of the many headwinds the industry has faced over this past year.”

‘Many Headwinds’
Consol spokesman Brian Aiello and Cloud Peak spokesman Rick Curtsinger didn’t respond to requests for comment. Gary Broadbent, spokesman for both Murray and Foresight, declined to comment.
While there’s plenty of uncertainty surrounding the coal business, there is one thing that traders and industry insiders agree on: There won’t be a rebound anytime soon.
“The world of coal will be very ugly in 2016,” said Ted O’Brien, chief executive officer at Doyle Trading Consultants, an independent consulting firm specializing in metals and mining. “All the bankruptcy filings that took place only helped on paper. It didn’t take away supply in the markets.”

Bill McKibben: The Fossil Fuel Industry Is Leading Its Own Zombie Apocalypse

Salon - Bill McKibben

No matter how many head shots it takes, it simply refuses to die. Big Oil could take the entire planet down with it
(Credit: Time Books/Steve Liptay)
When I was a kid, I was creepily fascinated by the wrongheaded idea, current in my grade school, that your hair and your fingernails kept growing after you died. The lesson seemed to be that it was hard to kill something off — if it wanted to keep going.
Something similar is happening right now with the fossil fuel industry. Even as the global warming crisis makes it clear that coal, natural gas, and oil are yesterday's energy, the momentum of two centuries of fossil fuel development means new projects keep emerging in a zombie-like fashion.
In fact, the climactic fight at the end of the fossil fuel era is already underway, even if it's happening almost in secret. That's because so much of the action isn't taking place in big, headline-grabbing climate change settings like the recent conference of 195 nations in Paris; it's taking place in hearing rooms and farmers' fields across this continent (and other continents, too).  Local activists are making desperate stands to stop new fossil fuel projects, while the giant energy companies are making equally desperate attempts to build while they still can. Though such conflicts and protests are mostly too small and local to attract national media attention, the outcome of these thousands of fights will do much to determine whether we emerge from this century with a habitable planet. In fact, far more than any set of paper promises by politicians, they really are the battle for the future.
Here's how Diane Leopold, president of the giant fracking company Dominion Energy, put it at a conference earlier this year: "It may be the most challenging" period in fossil fuel history, she said, because of "an increase in high-intensity opposition" to infrastructure projects that is becoming steadily "louder, better-funded, and more sophisticated." Or, in the words of the head of the American Natural Gas Association, referring to the bitter struggle between activists and the Canadian tar sands industry over the building of the Keystone XL pipeline, "Call it the Keystone-ization of every project that's out there."

Pipelines, Pipelines, Everywhere
I hesitate to even start listing them all, because I'm going to miss dozens, but here are some of the prospective pipelines people are currently fighting across North America: the Alberta Clipper and the Sandpiper pipelines in the upper Midwest, Enbridge Line 3, the Dakota Access, the Line 9 and Energy East pipelines in Ontario and environs, the Northern Gateway and Kinder Morgan pipelines in British Columbia, the Piñon pipeline in Navajo Country, the Sabal Trail pipeline in Alabama and Georgia, the Appalachian Connector, the Vermont Gas pipeline down the western side of my own state, the Algonquin pipeline, the Constitution pipeline, the Spectra pipeline, and on and on.
And it's not just pipelines, not by a long shot. I couldn't begin to start tallying up the number of proposed liquid natural gas terminals, prospective coal export facilities and new oil ports, fracking wells, and mountaintop removal coal sites where people are already waging serious trench warfare. As I write these words, brave activists are on trial for trying to block oil trains in the Pacific Northwest. In the Finger Lakes not a week goes by without mass arrests of local activists attempting to stop the building of a giant underground gas storage cavern. In California, it's frack wells in Kern County. As I said: endless.
And endlessly resourceful, too. Everywhere the opposition is forced by statute to make its stand not on climate change arguments, but on old grounds. This pipeline will hurt water quality. That coal port will increase local pollution. The dust that flies off those coal trains will cause asthma. All the arguments are perfectly correct and accurate and by themselves enough to justify stopping many of these plans, but a far more important argument always lurks in the background: each of these new infrastructure projects is a way to extend the life of the fossil fuel era a few more disastrous decades.
Here's the basic math: if you build a pipeline in 2016, the investment will be amortized for 40 years or more. It is designed to last — to carry coal slurry or gas or oil — well into the second half of the twenty-first century. It is, in other words, designed to do the very thing scientists insist we simply can't keep doing, and do it long past the point when physics swears we must stop.
These projects are the result of several kinds of momentum. Because fossil fuel companies have made huge sums of money for so long, they have the political clout to keep politicians saying yes. Just a week after the Paris accords were signed, for instance, the well-paid American employees of those companies, otherwise known as senators and representatives, overturned a 40-year-old ban on U.S. oil exports, a gift that an ExxonMobil spokesman had asked for in the most explicit terms only a few weeks earlier. "The sooner this happens, the better for us," he'd told the New York Times, at the very moment when other journalists were breaking the story of that company's epic three-decade legacy of deceit, its attempt to suppress public knowledge of a globally warming planet that Exxon officials knew they were helping to create. That scandal didn't matter. The habit of giving in to Big Oil was just too strong.

Driving a Stake Through a Fossil-Fueled World
The money, however, is only part of it. There's also a sense in which the whole process is simply on autopilot. For many decades the economic health of the nation and access to fossil fuels were more or less synonymous. So it's no wonder that the laws, statutes, and regulations favor business-as-usual. The advent of the environmental movement in the 1970s and 1980s introduced a few new rules, but they were only designed to keep that business-as-usual from going disastrously, visibly wrong. You could drill and mine and pump, but you were supposed to prevent the really obvious pollution. No Deepwater Horizons.  And so fossil fuel projects still get approved almost automatically, because there's no legal reason not to do so.
In Australia, for instance, a new prime minister, Malcolm Turnbull, replaced the climate-change-denying Tony Abbott. His minister for the environment, Greg Hunt, was a particular standout at the recent Paris talks, gassing on at great length about his "deeply personal" commitment to stopping climate change, calling the new pact the "most important environmental agreement ever." A month earlier, though, he'd approved plans for the largest coal mine on Earth, demanding slight revisions to make sure that the habitat of the southern black-throated finch would not be destroyed. Campaigners had hung much of their argument against the mine on the bird's possible extinction, since given the way Australia's laws are written this was one of the few hooks they had. The fact that scientists have stated quite plainly that such coal must remain in the ground if the globe is to meet its temperature targets and prevent catastrophic environmental changes has no standing. It's the most important argument in the world, but no one in authority can officially hear it.
It's not just Australia, of course. As 2016 began in my own Vermont — as enlightened a patch of territory as you're likely to find — the state's Public Service Board approved a big new gas pipeline. Under long-standing regulations, they said, it would be "in the public interest," even though science has recently made it clear that the methane leaking from the fracked gas the pipeline will carry is worse than the burning of coal. Their decision came two weeks after the temperature in the city of Burlington hit 68 on Christmas eve, breaking the old record by, oh, 17 degrees. But it didn't matter.
This zombie-like process is guaranteed to go on for years, even decades, as at every turn the fossil fuel industry fights the new laws and regulations that would be necessary, were agreements like the Paris accord to have any real teeth. The only way to short-circuit this process is to fight like hell, raising the political and economic price of new infrastructure to the point where politicians begin to balk. That's what happened with Keystone — when enough voices were raised, the powers-that-be finally decided it wasn't worth it. And it's happening elsewhere, too.  Other Canadian tar sands pipelines have also been blocked. Coal ports planned for the West Coast haven't been built. That Australian coal mine may have official approval, but almost every big bank in the world has balked at providing it the billions it would require.
There's much more of this fight coming — led, as usual, by indigenous groups, by farmers and ranchers, by people living on the front lines of both climate change and extractive industry. Increasingly they're being joined by climate scientists, faith communities, and students in last-ditch efforts to lock in fossil fuels. This will undoubtedly be a key battleground for the climate justice movement. In May, for instance, a vast coalition across six continents will engage in mass civil disobedience to "keep it in the ground."
And in a few places you can see more than just the opposition; you can see the next steps unfolding. Last fall, for instance, Portland, Oregon — the scene of a memorable "kayaktivist" blockade to keep Shell's Arctic drilling rigs bottled up in port — passed a remarkable resolution. No new fossil fuel infrastructure would be built in the city, its council and mayor declared. The law will almost certainly block a huge proposed propane export terminal, but far more important, it opens much wider the door to the future. If you can't do fossil fuel, after all, you have to do something else — sun, wind, conservation. This has to be our response to the living-dead future that the fossil fuel industry and its allied politicians imagine for our beleaguered world: no new fossil fuel infrastructure. None. The climate math is just too obvious.
This business of driving stakes through the heart of one project after another is exhausting. So many petitions, so many demonstrations, so many meetings. But at least for now, there's really no other way to kill a zombie.

Rising Global Temperatures: When Will Climate Change Deniers Throw In The Towel

Fairfax - Peter Hannam

Climate change deniers, it's time to throw in the towel. Photo: Tamara Voninski

Those reluctant to accept man-made climate change tend to resort to outlandish claims, such as the satellite data are doctored or that terrestrial weather stations operated by the Bureau of Meteorology have been manipulated to remove cooler readings to exaggerate the warming.
The former claim defies logic – what would NASA and other space agencies have to gain?
The almost 200 nations that signed up to the Paris climate agreement last month suggest the latter claim isn't very convincing for policymakers either.
In Australia, it's not hard to find statistics that point to a warming trend, with impacts that are often most notable during the bushfire season.
For instance, during the 1985-2000 period there was just one day that somewhere in Victoria hit a 45 degree maximum. During the most recent 15 years, the number of such days soared to 24, according to the bureau.
As researchers noted last year, record hot days in Australia are 12 times more likely than record cold ones since 2000.
Another favourite denial argument is that the planet hasn't warmed for the last 18 years, or some similar period.
The ruse relies on using a previous hot year – 1998 – in which the biggest El Nino on record provided a handy peak to compare later years against.
How come we didn't beat 1998 every year, since carbon emissions continued to climb, went the common refrain, happily ignoring the natural variations driven by influences such as the El Nino (hot) and La Nina (cool) cycles.
Climatologists look beyond any single year and instead focus on a warming trend in which average temperatures have risen 0.07 degrees per decade since 1880. The pace since 1970 has been 0.17 degrees. (See the chart below, showing the decadal trend).


Now 2015 has given us a year that was far warmer than the previous record hot year – which was 2014 – and one 0.27 degrees above the 1998 spike.
The so-called sceptics are unlikely to go away, despite the mounting evidence that the Earth is trapping more heat, greenhouse gases are the main factor and that a range of changes are under way, from increasing acidity of the oceans to declining levels of multi-year sea ice in the Arctic.
According to research by UK-based scientists Constantine Boussalis​ and Travis Coan, major conservative think tanks in the US are counter-intuitively stepping up their attacks on the science rather than the policies to deal with it.

Still, the record heat figures for 2015 – and the prospect that 2016 may be roughly as warm – means the case for climate change denial won't get off the ropes.

Paris Climate Limit Will See Some Parts Of World Warm By 6 Degrees: Nature Paper

Fairfax - Peter Hannam

The Paris pact to limit global temperature increases to less than 2 degrees will still result in some parts of the planet warming by as much as 6 degrees due to regional variations, researchers in Switzerland and Australia said.
While the world will likely pass two degrees of warming by the 2040s on the current trajectory of greenhouse gas emissions, some parts of the Arctic had already passed the 2-degree mark by 2000 compared with pre-industrial times, the scientists at ETH Zurich and the University of New South Wales found.
The Mediterranean, central Brazil and the lower 48 states of the US are among the areas likely to warm by 2 degrees by about 2030, according to the research published on Thursday in Nature journal.
The paper noted that purported impacts of drought in Syria and the regional unrest may be an indication of what is to come if worsening regional extreme undermine fragile socieities.
"Given current political tensions around the Mediterranean basin, implications of locally more rapid climate change could extend to regional impacts, adding to wider political instability," the paper said.


Globally, most land regions will warm faster than oceans in part because the loss of soil moisture and ice or snow amplifies the heating trend.
Sea circulation can also transport additional heat to ocean depths in a manner not possible on land, said Markus Donat, a research fellow at UNSW's ARC Centre for Excellence for Climate System Science and one of the paper's authors.
Interestingly, Australia generally avoids the biggest changes in land temperatures, roughly rising at the same pace as the global average, according to the modelling based on work done for the Intergovernmental Panel on Climate Change.
"There are two possible reasons [for the Australian result]," Andy Pitman, a co-author and director of the ARC Centre, said. "There is something peculiar about the nature of the feedbacks that link average and extreme warming," which leads to land areas in the southern hemisphere warming at a slower pace than in the north.
"Or, it could be that the models are biased to the areas where the modellers are based" in the northern Hemisphere, he said. "Perhaps there are systematic errors so we don't see the amplification."
At the Paris climate summit late last year, almost 200 nations agreed to keep average global warming to less than 2 degrees. On the pledges made so far, temperatures are on track to rise at least 2.7 degrees from pre-industrial times - assuming countries keep their promises to cut back greenhouse gas emissions towards zero net pollution by the second half of the century.
The global budget to keep within 2 degrees mean warming level is cumulative emissions of about 850 gigatonnes (GT) of carbon, the paper said.
To prevent the Mediterranean region warming by that amount, however, the budget is about 600 GT. Since emissions have totalled about 500 GT, rising at about 10 GT, the world has 10 years or less on current trends to avoid that mark, Professor Pitman said.
"It was an urgent problem 25 years ago," he said. "Now it's way past urgent to look at deep and meaningful emission reductions."
One reason for the urgency is that the pattern of warming is unlikely to be a smooth one, with unexpected "tipping points" accelerating the process.
"We have no way of knowing when our climate may change abruptly from one state to another, meaning we could potentially see even greater regional variation than these findings show," Dr Donat said.
The Arctic, as it warms, will likely see more melting of the permafrost, which will release more methane. Methane is about 25 times more potent in trapping heat than C02 over a century.
"Whilst Paris did put us on a better path, it's not a path that is consistent with the science," Professor Pitman said.

Lost At Sea: Rising Ocean CO2 Intoxicates Fish – Study

Climate Home - Alex Pashley

Burning fossil fuels could change ocean’s chemistry enough by 2050 to disorient and confuse marine life, scientists warn

Marine life could become dazed and confused if fossil fuel burning is not reined in, research suggests.
Carbon dioxide emissions that dissolve in the oceans “intoxicate” fish so they can’t spot predators or navigate, warned a study published in journal Nature on Wednesday.
“Essentially, the fish become lost at sea,” explained author Ben McNeil, of the University of New South Wales. “The carbon dioxide affects their brains and they lose their sense of direction and ability to find their way home. They don’t even know where their predators are.”
If atmospheric pollution continues to rise, the study found changing marine chemistry could affect creatures in some hotspots by mid-century. By 2100, up to half the world’s surface oceans will be toxic to their inhabitants.
The researchers drew on a global database with 30 years of seawater readings to study how ocean acidification causes the condition known as hypercapnia.
As ocean CO2 concentrations rise, so do incidences of hypercapnia. They could rise four times between 2000 and 2100. The vertical dashed line indicates the onset of hypercapnia, while the horizontal dashed line marks the time at which the surface ocean experiences such events.



Neil said the findings were “staggering” and had “massive implications for global fisheries and marine ecosystems around the planet.”
The researchers expect hypercapnia to occur when atmospheric concentrations of CO2 pass 650 parts per million.
The UN science climate panel says that could happen as early as 2050 if carbon emissions continue their unrelenting climb.
Capping warming to the 2C level agreed by 195 countries in Paris last year would stabilise levels at around 550ppm, however.
In 2015, the figure passed 400ppm for the first time in millions of years, as measured by the Mauna Loa Observatory in Hawaii.
