Coral Reefs under threat

Diversity of Corals, Algae in Warm Indian Ocean Suggests Resilience to Future Global Warming

Wednesday, February 17th, 2010

This is really good news for a small patch of reef…wish it could all find a way to protect itself against the human onslaught..

ScienceDaily (Feb. 15, 2010) — Penn State researchers and their international collaborators have discovered a diversity of corals harboring unusual species of symbiotic algae in the warm waters of the Andaman Sea in the northeastern Indian Ocean.

“The existence of so many novel coral symbioses thriving in a place that is too warm for most corals gives us hope that coral reefs and the ecosystems they support may persist — at least in some places — in the face of global warming,” said the team’s leader, Penn State Assistant Professor of Biology Todd LaJeunesse. According to LaJeunesse, the comprehensiveness of the team’s survey, which also included analysis of the corals and symbiotic algae living in the cooler western Indian Ocean and Great Barrier Reef area of Australia, is unparalleled by any other study.

The team’s findings will be published during the week ending 20 February 2010 in an early online issue of the Journal of Biogeography.

Corals are colonies of tiny animals that derive nutrients and energy from golden-brown, photosynthetic algae that live inside the corals’ cells. “This symbiotic relationship is sensitive to changes in the environment,” said LaJeunesse. “For example,

Guardian News: How do I know China wrecked the Copenhagen deal? I was in the room

Wednesday, December 23rd, 2009

Mark Lynas guardian.co.uk, Tuesday 22 December 2009 19.54 GMT

“Copenhagen was a disaster. That much is agreed. But the truth about what actually happened is in danger of being lost amid the spin and inevitable mutual recriminations. The truth is this: China wrecked the talks, intentionally humiliated Barack Obama, and insisted on an awful “deal” so western leaders would walk away carrying the blame. How do I know this? Because I was in the room and saw it happen.

China’s strategy was simple: block the open negotiations for two weeks, and then ensure that the closed-door deal made it look as if the west had failed the world’s poor once again. And sure enough, the aid agencies, civil society movements and environmental groups all took the bait. The failure was “the inevitable result of rich countries refusing adequately and fairly to shoulder their overwhelming responsibility”, said Christian Aid. “Rich countries have bullied developing nations,” fumed Friends of the Earth International.

All very predictable, but the complete opposite of the truth. Even George Monbiot, writing in yesterday’s Guardian, made the mistake of singly blaming Obama. But I saw Obama fighting desperately to salvage a deal, and the Chinese delegate saying “no”, over and over again. Monbiot even approvingly quoted the Sudanese delegate Lumumba Di-Aping, who denounced the Copenhagen accord as “a suicide pact, an incineration pact, in order to maintain the economic dominance of a few countries”.

Sudan behaves at the talks as a puppet of China; one of a number of countries that relieves the Chinese delegation of having to fight its battles in open sessions. It was a perfect stitch-up. China gutted the deal behind the scenes, and then left its proxies to savage it in public.

Here’s what actually went on late last Friday night, as heads of state from two dozen countries met behind closed doors. Obama was at the table for several hours, sitting between Gordon Brown and the Ethiopian prime minister, Meles Zenawi. The Danish prime minister chaired, and on his right sat Ban Ki-moon, secretary-general of the UN. Probably only about 50 or 60 people, including the heads of state, were in the room. I was attached to one of the delegations, whose head of state was also present for most of the time.

What I saw was profoundly shocking. The Chinese premier, Wen Jinbao, did not deign to attend the meetings personally, instead sending a second-tier official in the country’s foreign ministry to sit opposite Obama himself. The diplomatic snub was obvious and brutal, as was the practical implication: several times during the session, the world’s most powerful heads of state were forced to wait around as the Chinese delegate went off to make telephone calls to his “superiors”.

Shifting the blame

To those who would blame Obama and rich countries in general, know this: it was China’s representative who insisted that industrialised country targets, previously agreed as an 80% cut by 2050, be taken out of the deal. “Why can’t we even mention our own targets?” demanded a furious Angela Merkel. Australia’s prime minister, Kevin Rudd, was annoyed enough to bang his microphone. Brazil’s representative too pointed out the illogicality of China’s position. Why should rich countries not announce even this unilateral cut? The Chinese delegate said no, and I watched, aghast, as Merkel threw up her hands in despair and conceded the point. Now we know why – because China bet, correctly, that Obama would get the blame for the Copenhagen accord’s lack of ambition.

China, backed at times by India, then proceeded to take out all the numbers that mattered. A 2020 peaking year in global emissions, essential to restrain temperatures to 2C, was removed and replaced by woolly language suggesting that emissions should peak “as soon as possible”. The long-term target, of global 50% cuts by 2050, was also excised. No one else, perhaps with the exceptions of India and Saudi Arabia, wanted this to happen. I am certain that had the Chinese not been in the room, we would have left Copenhagen with a deal that had environmentalists popping champagne corks popping in every corner of the world.

Strong position

So how did China manage to pull off this coup? First, it was in an extremely strong negotiating position. China didn’t need a deal. As one developing country foreign minister said to me: “The Athenians had nothing to offer to the Spartans.” On the other hand, western leaders in particular – but also presidents Lula of Brazil, Zuma of South Africa, Calderón of Mexico and many others – were desperate for a positive outcome. Obama needed a strong deal perhaps more than anyone. The US had confirmed the offer of $100bn to developing countries for adaptation, put serious cuts on the table for the first time (17% below 2005 levels by 2020), and was obviously prepared to up its offer.

Above all, Obama needed to be able to demonstrate to the Senate that he could deliver China in any global climate regulation framework, so conservative senators could not argue that US carbon cuts would further advantage Chinese industry. With midterm elections looming, Obama and his staff also knew that Copenhagen would be probably their only opportunity to go to climate change talks with a strong mandate. This further strengthened China’s negotiating hand, as did the complete lack of civil society political pressure on either China or India. Campaign groups never blame developing countries for failure; this is an iron rule that is never broken. The Indians, in particular, have become past masters at co-opting the language of equity (“equal rights to the atmosphere”) in the service of planetary suicide – and leftish campaigners and commentators are hoist with their own petard.

With the deal gutted, the heads of state session concluded with a final battle as the Chinese delegate insisted on removing the 1.5C target so beloved of the small island states and low-lying nations who have most to lose from rising seas. President Nasheed of the Maldives, supported by Brown, fought valiantly to save this crucial number. “How can you ask my country to go extinct?” demanded Nasheed. The Chinese delegate feigned great offence – and the number stayed, but surrounded by language which makes it all but meaningless. The deed was done.

China’s game

All this raises the question: what is China’s game? Why did China, in the words of a UK-based analyst who also spent hours in heads of state meetings, “not only reject targets for itself, but also refuse to allow any other country to take on binding targets?” The analyst, who has attended climate conferences for more than 15 years, concludes that China wants to weaken the climate regulation regime now “in order to avoid the risk that it might be called on to be more ambitious in a few years’ time”.

This does not mean China is not serious about global warming. It is strong in both the wind and solar industries. But China’s growth, and growing global political and economic dominance, is based largely on cheap coal. China knows it is becoming an uncontested superpower; indeed its newfound muscular confidence was on striking display in Copenhagen. Its coal-based economy doubles every decade, and its power increases commensurately. Its leadership will not alter this magic formula unless they absolutely have to.

Copenhagen was much worse than just another bad deal, because it illustrated a profound shift in global geopolitics. This is fast becoming China’s century, yet its leadership has displayed that multilateral environmental governance is not only not a priority, but is viewed as a hindrance to the new superpower’s freedom of action. I left Copenhagen more despondent than I have felt in a long time. After all the hope and all the hype, the mobilisation of thousands, a wave of optimism crashed against the rock of global power politics, fell back, and drained away.”

Discovery of the Jekyll-and-Hyde Factors in ‘Coral Bleaching’

Monday, December 21st, 2009

“ScienceDaily (Dec. 7, 2009) — Scientists are reporting the first identification of substances involved in the Jekyll-and-Hyde transformation that changes harmless marine bacteria into killers that cause “coral bleaching.”

Their study appears in ACS’ Environmental Science & Technology, a semi-monthly journal.

Dan Bearden and colleagues note that bleaching already has destroyed up to 30 percent of the world’s coral reefs, and scientists are searching for ways to slow or stop the damage. One known culprit is an ocean-dwelling bacterium, Vibrio coralliilyticus, which chokes off corals’ energy supply and kills these shell-clad marine animals. At lower temperatures, the bacteria are harmless to coral. But at warmer temperatures (above 75 degrees Fahrenheit) the bacteria become virulent and can kill coral.

The new study reports identification of three chemicals — betaine, glutamate, and succinate — that V. coralliilyticus produces in warmer water and are involved in the transformation. The discovery opens the door to understanding the biology involved in the complex interactions between corals and bacteria and unraveling the mystery of coral bleaching, the scientists indicated.”

“Seahorse ‘hitchhikes’ Atlantic”

Thursday, November 19th, 2009

(BBC)

“Navigating the world’s oceans can be a difficult task for anyone.

For a tiny seahorse with only small fins and a tail for locomotion it seems an impossible task.


However, a seahorse that lives on the western coast of the Atlantic has been found in the Azores almost 5000km away from its possible home.

Researchers suggest the seahorse may have completed the epic journey using its prehensile tail to hitch a ride on a raft of floating sea grass.

An international team of researchers from the UK and the Azores publish their discovery in the Journal of Fish Biology.

Lost at sea

The seahorse was found by a fisherman on the isolated Azores archipelago in the eastern Atlantic.

Two species of seahorse Hippocampus guttulatus and Hippocampus hippocampus are native to Europe and the Azores, an autonomous region of Portugal.

We were surprised to identify the unknown seahorse as H. erectus, as this species is found thousands of kilometres away

The researchers compared the morphology and DNA of the seahorse with the two native species and found it was a lined seahorse Hippocampus erectus usually found along the Atlantic coast and Caribbean sea coasts of North, Central and South America….”

Stop polluting Belize’s tropical rivers and stop the smokescreen, Probe International tells Fortis Inc.

Wednesday, October 7th, 2009

“International aid and trade watchdog, Probe International, is asking Stanley Marshall, President and CEO of the Newfoundland-based power company Fortis Inc., to start accounting to the people of Belize and its shareholders about contamination of the Macal and Belize Rivers in Belize by the company’s Chalillo dam.

Aerial photographs released in early August show that the dam is discharging sediment-laced water and contaminating the downstream river with turbidity levels hundreds, if not thousands, of times higher than the standards set by the World Health Organization and the U.S. Environmental Protection Agency. The contamination has now reached the Caribbean Sea.

Turbidity contaminants are especially worrying, says Patricia Adams, the author of the letter and Executive Director of Probe International, because (more…)

The world’s private transport needs to go electric

Thursday, May 14th, 2009

(Nadine Pedoe)

There are some bold plans afoot to get everyone into electric cars (at least those who aren’t already on public transport or using their own power to travel). At least 30% of the world’s carbon emissions come from using fossil fuels in our vehicles. With carbon emissions contributing daily to global warming and the destruction of our reefs among so many other living things, we need to do something to stop this immediately. On Caye Caulker, we only have a short distance to travel on land, and almost everyone is foot, pedal or electric powered. We have the clean, breathable air to prove it.  Red Mangrove uses low-emission, low fuel consumption boat engines too. Sadly not all the boats here are similarly equipped.

Of course there are problems with electric cars (and golf carts). (more…)
