FORT LAUDERDALE, U.S., Jul 10 (IPS) – One third of reef-building corals already face extinction because of climate change, the first-ever global assessment has found.

Reefs are made up of hundreds of coral species, and a two-year study to determine the current status of corals has discovered that 231 of the 704 species assessed will be “red-listed” Thursday. This means these 231 species meet the International Union for Conservation of Nature (IUCN) Red List Criteria for species at risk of extinction in the near future.

Previously, only 10 species of corals had been red-listed, mainly because no proper assessment had been done before.

“We were not expecting the numbers to be that high,” said Suzanne Livingstone of the IUCN’s Global Marine Species Assessment (GMSA) in Norfolk, Virginia. The paper was published Thursday in Science.

If the same assessment of corals had been done 20 years ago, only 13 of the 704 species would have been red-listed, Livingstone told IPS at the 11th International Coral Reef Symposium (ICRS) in Fort Lauderdale, Florida. However, in that short time span, climate change has warmed the oceans and begun to make them more acidic and corals are suffering.

“It’s frightening when you think about it,” she said.

Global Fish Catches Vastly Underestimated

FORT LAUDERDALE, U.S., Jul 8 (IPS) – Fish catches in tropical island nations may be as much as 17 times higher than officially reported, according to a new study released Tuesday.

“The underreporting of fish catches is of such a magnitude it boggles the mind,” said Daniel Pauly, a renowned fisheries expert at the University of British Columbia (UBC).

All of the 20 small Pacific island countries in the study underreported catches, mainly because they did not count the catch by small-scale local fishers. This is not unique — even the U.S. does not report local and recreational fishing statistics, Pauly told IPS at the 11th International Coral Reef Symposium (ICRS) in Fort Lauderdale, Florida Tuesday.

A different study also released Tuesday estimates that the unreported recreational fish catch in the Hawaiian Islands doubles the size of the official catch. It also concluded that 75 percent of reef fishes in the main Hawaiian Islands are depleted or in critical condition because of overfishing. Continue reading →

Life Support Needed For Coral Reefs

FORT LAUDERDALE, U.S., Jul 8 (IPS) – Coral reefs need to be put on “life support” if they are to survive climate change, but their ultimate survival is dependant on major reductions in fossil fuel emissions, say experts.

“We’re going to hear lots of bad news about corals in the next few decades,” Rich Aronson, president of the International Society for Reef Studies, told 3,000 scientists, conservationists and policy makers at the 11th International Coral Reef Symposium (ICRS) in Fort Lauderdale, Florida Monday.

Climate change is making the ocean too warm and too acidic for most corals species to survive beyond the year 2050, many marine scientists now believe.

“The situation is serious to the point of desperation,” Aronson told IPS in an interview.

Past and present carbon emissions from burning fossil fuels have already altered the oceans, leading to declines in corals in many areas. This trend will continue for decades even if it were possible to eliminate all emissions today, scientists say. Current emissions are running at eight to nine gigatonnes a year and rising, resulting in dramatically altered oceans where few of the current coral species will be able to survive.

“This is a pivotal moment. We must act strongly and immediately if we are to have coral reefs as we know them,” Aronson said. Continue reading →

Failure on Global Warming “Un-American”

KINGSTON, Ontario, Jun 25 (IPS) – North America’s abject failure to meet the challenge of climate change has been “un-American”, environmentalist and scientist David Suzuki told delegates Tuesday at the World Wind Energy Conference, the first ever in the region.

“We’re facing an ecological crisis, a crisis far, far worse than Pearl Harbour,” Suzuki said.

Twenty years ago this week, one of the United States’ leading scientists warned Congress of the imminent danger of climate change and said that waiting decades to take action was too risky. Now James E. Hansen of the National Aeronautics and Space Administration has published new research indicating that greenhouse gas concentrations have pushed the climate near a dangerous tipping point that will unleash far-reaching changes in the atmosphere and oceans that could take millennia to reverse.

100% Renewable Energy Can Power Nations experts say

To prevent a climate crisis, Hansen calls for deep reductions in carbon dioxide emissions, beginning almost immediately, including a phase out of coal-fired power plants by 2030. Continue reading →

Soaring Energy Costs May Force Low-CO2 Living

Jun 5 (IPS) – Climate change is a global problem but individuals and communities can take simple measures to cut their carbon emissions in half, experts said Thursday on World Environment Day.

The U.N. Environment Programme (UNEP) launched a “Kick the CO2 Habit” campaign in Wellington, New Zealand today to encourage low-carbon lifestyle choices at home and when travelling.

“The public have the power to change the future — have the power to personally and collectively influence economies to ‘Kick the CO2 Habit’,” said Achim Steiner, UNEP executive director.

UNEP released a kind of “Rough Guide” to low-carbon living, entitled “Kick the Habit: The UN Guide to Climate Neutrality“, which is available free online.

The knowledge and technology to dramatically reduce carbon emissions already exist, mainly through improvements in energy efficiency. What have been lacking in most countries are incentives to make changes. Now the hard stick of high energy prices has given the public new interest in reducing energy costs, which also reduce carbon emissions. Continue reading →

International Enviro Standards Needed for Biofuels

By Stephen Leahy

BONN, Jun 5 (Tierramérica) – The adoption of international standards for the sustainable production of biofuels emerged as a controversial approach at the recent United Nations conference on biodiversity here.

The still-vague proposals suggest that they would “promote the sustainable production, conversion, use, and trade of biofuels”, and revolve around reducing “perverse incentives” like farm subsidies in Europe and the United States.

“In 33 years of ethanol production, Brazil has never bothered to set up sustainability standards,” said Camila Moreno, a researcher with the Brazilian environmental group Terra de Direitos.

Also known as agro-fuels, made from crops like maize, sugarcane and soybeans, they face criticism from those who blame them for the current global food crisis.

The biofuel market is also accused of aggravating the destruction of ecosystems by pushing other crops to cut down forests and expand the farming frontier. Indeed, halting the growing tide of extinctions of plant and animals species was the focus of the Bonn meeting. Continue reading →

Male Infertility Linked to Pesticides

Stephen Agriculture/Food, ENVIRONMENT, News, Pollution and Toxics ,

Pesticide exposure is widespread in North America and has long been associated with human health impacts. Here’s yet more proof: A June 2008 review of scientific studies on pesticide exposure shows a decline in semen quality and reduced male fertility.

“The conclusion can be drawn that pesticide exposure may affect spermatogenesis leading to poor semen quality and reduced male fertility.” — Current Opinion in Obstetrics & Gynecology

“We’re Running the Risk of Unstoppable Climate Change” — Oceanographer

Interview with leading marine scientist Chris Reid

“I’m afraid it is going to take a major catastrophe in the developed world…”

GIJON, Spain, Jun 4 (IPS) – Warming seawater, melting sea ice and glaciers, sea level rise, storm intensification, changes in ocean currents, growing “dead zones”, and ocean acidification are just some of the signs that the oceans that cover 71 percent of our watery planet are changing.

Changes in the oceans also means major impacts on the land and the atmosphere. “Policy makers and the public do not realize that the oceans are the drivers of the climate system,” says Chris Reid, recently retired professor of oceanography at the Sir Alister Hardy Foundation for Ocean Science in Plymouth, England.

Reid will be producing a report this summer on the impacts the altered oceans are having and will have on the global climate.

IPS environment correspondent Stephen Leahy spoke to Reid at an international scientific symposium held late last month in Gijon, Spain on the effects of climate change on the world’s oceans.

IPS: What is happening in the oceans that will affect the global climate?

CR: The oceans have absorbed 30 percent of all human emissions of carbon dioxide (CO2) since the start of the industrial age. There is now good evidence that the oceans are absorbing less carbon as a result of climate change. The warming of surface waters, glacial and sea ice meltwater, acidification and so on are inhibiting or slowing a number of the oceans’ mechanisms for absorbing carbon from the atmosphere and safely storing them in the deep ocean.

IPS: How will that affect us?

CR: It means the atmospheric concentrations of CO2 will rise much faster than has been previously projected by climate scientists. Human carbon emissions are already on pace for the worst case scenario as envisioned by the IPCC (Intergovernmental Panel on Climate Change). These changes in the oceans means the rate of warming will increase, bringing even more severe hurricanes and cyclones, flooding events and so on.

IPS: Cyclones like the one that recently devastated Burma?

CR: Yes. Research presented at this meeting shows that South Korea and Japan are experiencing more powerful cyclones. While a single event can’t be precisely connected to climate change, the Burma cyclone fits what is expected with climate change. Continue reading →

Canada “acting like USA” Torpedoes International Enviro Agreement

“Do Canadians know what their government is doing here? You must tell them.” — Mamadou Mana Diakite of Mali

BONN, Jun 3 (IPS) – Self-interest and petty politicking largely paralysed efforts to solve the urgent problem of the widespread extinction of species, with few concrete achievements after nearly two weeks of 14-hour meetings at the Convention on Biodiversity (CBD) in Bonn that concluded last Friday.

Why? Mainly because a few rich and powerful countries like Japan, Canada, Australia, Brazil and China fought tooth and nail to boost their own self-interest regardless of the environmental and human costs.

Six years ago, more than 160 countries at the April 2002 World Summit on Sustainable Development in Johannesburg agreed on a target of achieving a significant reduction of the current rate of biodiversity loss by 2010. In May 2008, virtually everyone here acknowledged the target will not be met.

Some countries, like Germany and most of the developing world, do understand that species extinction is undermining the vital ecosystem services that nature provides, such as food, fibre, clean water and air. Others, such as Canada, express altruistic sentiments that are belied by their actions. Since decisions at U.N. meetings are by consensus, any country can block decisions on a whim. Or, as is more often the case, countries will block agreement on something they have no connection to simply so they can force concessions on other issues.

“You listen to them debate over every comma and realise they could be arguing over anything,” said Helena Paul of EcoNexus, a British-based environmental group that participated in the CBD meetings. NGOs can observe but are not participants except for the occasional opportunity to express their views. Continue reading →

Greed Stalls 21st Century Bio-Economy

By Stephen Leahy

BONN, May 31 (IPS) – The world community took some ever-so-careful steps towards slowing the biodiversity crisis at a major U.N. meeting in Bonn, while emphasising the need for urgency and action.

Agreement on the need for more protected areas in tropical forests and oceans was universal, but only Germany offered any new funding. On the contentious issue of biofuels and their impacts on food and biodiversity, members agreed at the last minute that biofuels production ought to be environmentally sustainable and not impact biodiversity. There was also an agreement on a de facto moratorium on ocean fertilisation schemes.

German Chancellor Angela Merkel pledged $785 million a year to protect forests.

And, after 16 years of meetings, the 168 nations that have ratified the Convention on Biodiversity (CBD) agreed to a final two-year timetable to establish an asset and benefit sharing (ABS) regime.

ABS is about access to biodiversity and equitable sharing of benefits resulting from its use. The intent is to end “biopiracy” — the exploitation of indigenous plants and animals for profit without permission or compensation — and reverse countries’ denial of access to any native species for scientific or commercial purposes. Half of all synthetic drugs have been derived from plants or insects.

“This is a real breakthrough. This agreement is a detailed framework on how to put ABS into place,” said German Environment Minister Sigmar Gabriel, who is also the president of the CBD for the next two years.

It might seem strange that delegates enthusiastically cheered this “Bonn Mandate”, an agreement to have two more years of meetings. But in fact, Japan, Canada, New Zealand and Australia have fought hard against anything resembling a legal obligation to compensate countries in the developing world for the use of their genetic resources, a delegate from Malaysia told IPS:

“They don’t want to share any money they’ve made from using our biodiversity.” Continue reading →
