China’s economic boom has seen its coral reefs shrink by at least 80 percent over the past 30 years, according to a joint Australian study, with researchers describing “grim” levels of damage and loss.
Scientists from the Australian Research Council Centre of Excellence for Coral Reef Studies and the South China Sea Institute of Oceanology said their survey of mainland China and South China Sea reefs showed alarming degradation.
“We found that coral abundance has declined by at least 80 percent over the past 30 years on coastal fringing reefs along the Chinese mainland and adjoining Hainan Island,” said the study, published in the latest edition of the journal Conservation Biology.
“On offshore atolls and archipelagos claimed by six countries in the South China Sea, coral cover has declined from an average of greater than 60 percent to around 20 percent within the past 10-15 years,” it added.
Coastal development, pollution and overfishing linked to the Asian giant’s aggressive economic expansion were the major drivers, the authors said, describing a “grim picture of decline, degradation and destruction”.
“China’s ongoing economic expansion has exacerbated many wicked environmental problems, including widespread habitat loss due to coastal development, unsustainable levels of fishing, and pollution,” the study said.
Coral loss in the South China Sea — where reefs stretch across some 30,000 square kilometres (12,000 square miles) — was compounded by poor governance stemming from competing territorial claims.
Some marine parks aimed at conservation had been established but study author Terry Hughes said they were too small and too far apart to arrest the decline in coral cover.
“The window of opportunity to recover the reefs of the South China Sea is closing rapidly, given the state of degradation revealed in this study,” he said.
The South China Sea is strategically significant, home to some of the world’s most important shipping lanes and believed to be rich in resources.
China claims most of the sea including waters close to the shores of its neighbours. Rival claimants include Brunei, Malaysia, the Philippines and Vietnam, and tensions over the issue have flared in recent years.

Plant and animal species are shifting their geographic ranges and the timing of their life events – such as flowering, laying eggs or migrating – at faster rates than researchers documented just a few years ago, according to a technical report on biodiversity and ecosystems used as scientific input for the 2013 Third National Climate Assessment.
The report, Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services, synthesizes the scientific understanding of the way climate change is affecting ecosystems, ecosystem services and the diversity of species, as well as what strategies might be used by natural resource practitioners to decrease current and future risks. More than 60 federal, academic and other scientists, including the lead authors from the U.S. Geological Survey, the National Wildlife Federation and Arizona State University in Tempe, authored the assessment.
“These geographic range and timing changes are causing cascading effects that extend through ecosystems, bringing together species that haven’t previously interacted and creating mismatches between animals and their food sources,” said Nancy Grimm, a scientist at ASU and a lead author of the report.
Grimm explained that such mismatches in the availability and timing of natural resources can influence species’ survival; for example, if insects emerge well before the arrival of migrating birds that rely on them for food, it can adversely affect bird populations. Earlier thaw and shorter winters can extend growing seasons for insect pests such as bark beetles, having devastating consequences for the way ecosystems are structured and function. This can substantially alter the benefits people derive from ecosystems, such as clean water, wood products and food.
“The impact of climate change on ecosystems has important implications for people and communities,” said Amanda Staudt, a NWF climate scientist and a lead author on the report. “Shifting climate conditions are affecting valuable ecosystem services, such as the role that coastal habitats play in dampening storm surge or the ability of our forests to provide timber and help filter our drinking water.”
Another key finding is the mounting evidence that population declines and increased extinction risks for some plant and animal species can be directly attributed to climate change. The most vulnerable species are those already degraded by other human-caused stressors such as pollution or exploitation, unable to shift their geographic range or timing of key life events, or that have narrow environmental or ecological tolerance. For example, species that must live at high altitudes or live in cold water with a narrow temperature range, such as salmon, face an even greater risk due to climate change.
“The report clearly indicates that as climate change continues to impact ecological systems, a net loss of global species’ diversity, as well as major shifts in the provision of ecosystem services, are quite likely,” said Michelle Staudinger, a lead author of the report and a USGS and University of Missouri scientist.
For example, she added, climate change is already causing shifts in the abundance and geographic range of economically important marine fish. “These changes will almost certainly continue, resulting in some local fisheries declining or disappearing while others may grow and become more valuable if fishing communities can find socially and economically viable ways to adapt to these changes.”
Natural resource managers are already contending with what climate change means for the way they approach conservation. For example, the report stated, land managers are now more focused on the connectivity of protected habitats, which can improve a species’ ability to shift its geographic range to follow optimal conditions for survival.
“The conservation community is grappling with how we manage our natural resources in the face of climate change, so that we can help our ecosystems to continue meeting the needs of both people and wildlife,” said Bruce Stein, a lead author of the report and director of climate adaptation at the National Wildlife Federation.
Other key findings of the report include:
- Changes in precipitation and extreme weather events can overwhelm the ability of natural systems to reduce or prevent harm to people from these events. For example, more frequent heavy rainfall events increase the movement of nutrients and pollutants to downstream ecosystems, likely resulting not only in ecosystem change, but also in adverse changes in the quality of drinking water and a greater risk of waterborne-disease outbreaks.
- Changes in winter have big and surprising effects on ecosystems and their services. Changes in soil freezing, snow cover and air temperature affect the ability of ecosystems to store carbon, which, in turn, influences agricultural and forest production. Seasonally snow-covered regions are especially susceptible to climate change because small precipitation or temperature shifts can cause large ecosystem changes. Longer growing seasons and warmer winters are already increasing the likelihood of pest outbreaks, leading to tree mortality and more intense, extensive fires. Decreased or unreliable snowfall for winter sports and recreation will likely cause high future economic losses.
- The ecosystem services provided by coastal habitats are especially vulnerable to sea-level rise and more severe storms. The Atlantic and Gulf of Mexico coasts are most vulnerable to the loss of coastal protection services provided by wetlands and coral reefs. Along the Pacific coast, long-term dune erosion caused by increasing wave heights is projected to cause problems for communities and for recreational beach activities. However, other kinds of recreation will probably improve due to better weather, with the net effect being that visitors and tourism dollars will shift away from some communities in favor of others.
- Climate change adaptation strategies are vital for the conservation of diverse species and effective natural resource policy and management. As moreadaptive management approaches are developed, resource managers can enhance the country’s ability to respond to the impacts of climate change through forward-looking and climate science-informed goals and actions.
- Ecological monitoring needs to be improved and better coordinated among federal and state agencies to ensure the impacts of climate change are adequately monitored and to support ecological research, management, assessment and policy. Existing tracking networks in the United States will need to improve coverage through time and in geographic area to detect and track climate-induced shifts in ecosystems and species.

Coal is likely to rival oil as the world’s biggest source of energy in the next five years, with potentially disastrous consequences for the climate, according to the world’s leading authority on energy economics.
One of the biggest factors behind the rise in coal use has been the massive increase in the use of shale gas in the US.
Coal consumption is increasing all over the world – even in countries and regions with carbon-cutting targets – except the US, where shale gas has displaced coal, shows new research from the International Energy Agency (IEA). The decline of the fuel in the US has helped to cut prices for coal globally, which has made it more attractive, even in Europe where coal use was supposed to be discouraged by the emissions trading scheme.
Maria van der Hoeven, executive director of the IEA, said: “Coal’s share of the global energy mix continues to grow each year, and if no changes are made to current policies, coal will catch oil within a decade.”
Coal is abundant and found in most regions of the world, unlike conventional oil and gas, and can be cheaply extracted. As a result, coal was used to meet nearly half of the rise in demand for energy globally in the past decade. According to the IEA, demand from China and India will drive world coal use in the coming five years, with India on course to overtake the US as the world’s second biggest consumer. China is the biggest coal importer, and Indonesia the biggest exporter, having temporarily overtaken Australia.
According to the IEA’s Medium Term Coal Market Report, published on Tuesday morning, the world will burn 1.2bn more tonnes of coal per year by 2017 compared with today – the equivalent of the current coal consumption of Russia and the US combined. Global coal consumption is forecast to reach 4.3bn tonnes of oil equivalent by 2017, while oil consumption is forecast to reach 4.4bn tonnes by the same date.
With the highest carbon emissions of any major fossil fuel, coal is a huge contributor to climate change, particularly when burned in old-fashioned, inefficient power stations. When these are not equipped with special “scrubbing” equipment to remove chemicals, coal can also produce sulphur emissions – the leading cause of acid rain – and other pollutants such as mercury and soot particles.

A new report by the NGO, International Rivers, takes an in-depth look at the role China is playing in building mega-dams worldwide. According to the report, Chinese companies are involved in 308 hydroelectric projects across 70 nations. While dams are often billed as “green energy,” they can have massive ecological impacts on rivers, raise local conflict, and even expel significant levels of greenhouse gases when built in the tropics.
“The Chinese state owned Sinohydro Corporation is now the largest hydropower company in the world. Many Chinese companies involved in the construction of large hydropower projects such as the Three Gorges Dam are now taking the lead role in new hydropower projects around the world,” reads the report which adds that “the China Export-Import Bank (China Exim Bank) has become a major funder of large dams.”
Nearly half of the dams in question are planned for Southeast Asia, while 28 percent are planned for Africa and 8 percent for Latin America. Since 2008, the number of dams that the Chinese are involved in has grown by 300 percent. Yet many of these projects lack any or stringent environmental and social policies.
“Few Chinese dam builders and financiers have adopted environmental policies in line with international standards,” the report notes, adding that Chinese companies have been involved with building notorious dams, such as the Gibe III in Ethiopia, the Bukan Dam in Malaysia, the Myitsone Dam in Myanmar, and the Merowe Dam in Sudan.
For example, over 50,000 people were forcibly moved in order to build the Merowe Dam. According to the report, the Sudan government “brutally oppressed any protests. Several people were killed and many more were injured in crack-downs by the security forces.”
A number of Chinese-financed dams have faced local and global resistance. Progress has been made in some cases: this year the Sinohydro Corporation has adopted its first ever environmental policy.
“Among other provisions, the world’s biggest hydropower company commits to fully comply with applicable laws on all levels, adopt all World Bank safeguard policies, respect ‘no go’ zones including national parks and World heritage sites, conduct an open dialogue with local communities and NGOs, and create complaint mechanisms for all of its projects,” according to the report.
Still International Rivers warns that “environmental policies are only as good as their implementation on the ground. This will be the next great challenge for Sinohydro.”

For residents in Assumption Parish, the boiling, gas-belching bayou, with its expanding toxic sinkhole and quaking earth is no longer a mystery; but there is little comfort in knowing the source of the little-known event that has forced them out of their homes.
Located about 45 miles south of Baton Rouge, Assumption Parish carries all the charms and curses of southern Louisiana. Networks of bayous, dotted with trees heavy with Spanish moss, connect with the Mississippi River as it slowly ambles toward the Gulf of Mexico. Fishermen and farmers make their homes there, and so does the oil and gas industry, which has woven its own network of wells, pipelines and processing facilities across the lowland landscape.
The first sign of the oncoming disaster was the mysterious appearance of bubbles in the bayous in the spring of 2012. For months the residents of a rural community in Assumption Parish wondered why the waters seemed to be boiling in certain spots as they navigated the bayous in their fishing boats.
Then came the earthquakes. The quakes were relatively small, but some residents reported that their houses shifted in position, and the tremors shook a community already desperate for answers. State officials launched an investigation into the earthquakes and bubbling bayous in response to public outcry, but the officials figured the bubbles were caused by a single source of natural gas, such as a pipeline leak. They were wrong.
On a summer night in early August, the earth below the Bayou Corne, located near a small residential community in Assumption, simply opened up and gave way. Several acres of swamp forest were swallowed up and replaced with a gaping sinkhole that filled itself with water, underground brines, oil and natural gas from deep below the surface. Since then, the massive sinkhole at Bayou Corne has grown to 8 acres in size.
On August 3, Louisiana Gov. Bobby Jindal declared a statewide emergency, and local officials in Assumption ordered the mandatory evacuation of about 300 residents of more than 150 homes located about a half-mile from the sinkhole. Four months later, officials continue to tell residents that they do not know when they will be able to return home. A few have chosen to ignore the order and have stayed in their homes, but the neighborhood is now quiet and nearly vacant. Across the road from the residential community, a parking lot near a small boat launch ramp has been converted to a command post for state police and emergency responders.
“This place is no longer fit for human habitation, and will forever be,” shouted one frustrated evacuee at a recent community meeting in Assumption.
The Bayou Corne sinkhole is an unprecedented environmental disaster. Geologists say they have never dealt with anything quite like it before, but the sinkhole has made few headlines beyond the local media. No news may be good news for Texas Brine, a Houston-based drilling and storage firm that for years milked an underground salt cavern on the edge of large salt formation deep below the sinkhole area. From oil and gas drilling, to making chloride and other chemicals needed for plastics and chemical processing, the salty brine produced by such wells is the lifeblood of the petrochemical industry.
Geologists and state officials now believe that Texas Brine’s production cavern below Bayou Corne collapsed from the side and filled with rock, oil and gas from deposits around the salt formation. The pressure in the cavern was too great and caused a “frack out.” Like Mother Nature’s own version of the controversial oil and gas drilling technique known as “fracking,” brine and other liquids were forced vertically out of the salt cavern, fracturing rock toward the surface and causing the ground to give way.
“In the oil field, you’ve heard of hydraulic fracturing; that’s what they’re using to develop gas and oil wells around the country …”What is a frack-out is, is when you get the pressure too high and instead of fracturing where you want, it fractures all the way to the surface,” said Gary Hecox, a geologist with the Shaw Environmental Group, at a recent community meeting in Assumption Parish. Texas Brine brought in the Shaw group to help mitigate the sinkhole.
As the weeks went by, officials determined the unstable salt cavern was to blame for the mysterious tremors and bubbling bayous. Texas Brine publically claimed the failure of the cavern was caused by seismic activity and refused to take responsibility for the sinkhole, but the United States Geological Survey (USGS) has since determined that the collapsing cavern caused the tremors felt in the neighborhood, not the other way around.
According to Hecox and the USGS, the collapsing cavern shifted and weakened underground rock formations, causing the earthquakes and allowing natural gas and oil to migrate upward and contaminate the local groundwater aquifer. Gas continues to force its way up, and now a layer of gas sits on top of the aquifer and leaches through the ground into the bayous, causing the water to bubble up in several spots. Gas moves much faster through water than oil, which explains why the bubbles have not been accompanied by a familiar sheen.
Documents obtained by the Baton Rouge newspaper, The Advocate, revealed that in 2011, Texas Brine sent a letter to the Louisiana Department of Natural Resources (DNR) to alert its director, Joseph Ball, that the cavern had failed a “mechanical integrity test” and would be capped and shut down. The DNR received the letter but did not require any additional monitoring of the well’s integrity.
Despite this letter, regulators apparently did not suspect the brine cavern to be the source of the bubbles until a few days before the sinkhole appeared, The Advocate reported. The letter raised ire among local officials, who did not hear about the failed integrity test until after Bayou Corne became a slurry pit.
Texas Brine spokesmen Sonny Cranch told Truthout the company has not officially taken responsibility for the sinkhole disaster, but has “acknowledged that there is a relationship” between the collapsed cavern and the sinkhole.

Global carbon dioxide (CO2) emissions are set to rise again in 2012, reaching a record high of 35.6 billion tonnes – according to new figures from the Global Carbon Project, co-led by researchers from the Tyndall Centre for Climate Change Research at the University of East Anglia (UEA).
The 2.6 per cent rise projected for 2012 means global emissions from burning fossil fuel are 58 per cent above 1990 levels, the baseline year for the Kyoto Protocol.
By University of East Anglia
This latest analysis by the Global Carbon Project is published today in the journal Nature Climate Change with full data released simultaneously by the journal Earth System Science Data Discussions.
It shows the biggest contributors to global emissions in 2011 were China (28 per cent), the United States (16 per cent), the European Union (11 per cent), and India (7 per cent).
Emissions in China and India grew by 9.9 and 7.5 per cent in 2011, while those of the United States and the European Union decreased by 1.8 and 2.8 per cent.
Emissions per person in China of 6.6 tonnes of CO2 were nearly as high as those of the European Union (7.3), but still below the 17.2 tonnes of carbon used in the United States. Emissions in India were lower at 1.8 tonnes of carbon per person.
Prof Corinne Le Quéré, director of the Tyndall Centre for Climate Change Research and professor at UEA, led the publication of the data. She said: “These latest figures come amidst climate talks in Doha. But with emissions continuing to grow, it‟s as if no-one is listening to the entire scientific community.”
The 2012 rise further opens the gap between real-world emissions and those required to keep global warming below the international target of two degrees.
“I am worried that the risks of dangerous climate change are too high on our current emissions trajectory. We need a radical plan,” added Prof Corinne Le Quéré.
The analysis published in Nature Climate Change shows significant emission reductions are needed by 2020 to keep two degrees as a feasible goal.
It shows previous energy transitions in Belgium, Denmark, France, Sweden, and the UK have led to emission reductions as high as 5 per cent each year over decade-long periods, even without climate policy.
Lead author Dr Glen Peters, of the Centre for International Climate and Environmental Research in Norway, said: “Scaling up similar energy transitions across more countries can kick-start global mitigation with low costs. To deepen and sustain these energy transitions in a broad range of countries requires aggressive policy drivers.”
Co-author Dr Charlie Wilson, of the Tyndall Centre at UEA, added: “Public policies and institutions have a central role to play in supporting the widespread deployment of low carbon and efficient energy-using technologies, and in supporting innovation efforts”.
Emissions from deforestation and other land-use change added 10 per cent to the emissions from burning fossil fuels. The CO2 concentration in the atmosphere reached 391 parts per million (ppm) at the end of 2011.
These results lends further urgency to recent reports that current emissions pathways are already dangerously high and could lead to serious impacts and high costs on society. These other analyses come from the International Energy Agency, the United Nations Environment Programme, the World Bank, the European Environment Agency, and PricewaterhouseCoopers.
