A solar-powered aircraft will take flight next month from Switzerland with hopes ultimately to circle the Earth in 2012, without fuel, and stopping every five days only to change pilots.

“I’m intrigued by the vision of perpetual flight,” mechanical engineer Andre Borschberg, chief executive of the 100-million-dollar Solar Impulse project, told Tierramérica.

Designed to use only energy from the sun during the day and run on sun-charged batteries at night, it could stay aloft perpetually, like a giant version of the thin-winged Arctic tern that migrates annually from the Antarctic to the Arctic, non-stop.

“The big lesson of the Wright brothers is that if you don’t try you never succeed,” Borschberg told Tierramérica in the Dübendorf Airfield hanger outside of Zurich, where the first prototype was being assembled for a test flight in October or November.

solar impulse2The U.S. inventors Orville and Wilber Wright are credited with the first airplane flight in 1903. “They never dreamed that a plane could cross the Atlantic Ocean, and yet less than 25 years later (in 1927) Charles Lindbergh flew from New York to Paris,” Borschberg said.

“It is our hope that the Solar Impulse will be a symbol to the world and create awareness about our own energy use,” he added.

The Solar Impulse HB-SIA prototype plane is essentially a 64-metre long thin wing with four small propellers and narrow pilot pod and tail attached underneath.

Sitting in the airport hangar, even with its inner workings exposed, it doesn’t look like much more than a big paper glider – not much for 100 million dollars. Continue reading →

Climate Survival Means Anticipating and Adapting

GENEVA, Sep 8 (IPS)

Imagine being able to know months in advance when and where floods or droughts may occur.

That is what over 150 countries participating in the third World Climate Conference, which concluded last Friday in Geneva, pledged to achieve through the creation of a Global Framework for Climate Services.

“Today is a landmark day for making climate services available to all people,” said Michel Jarraud, secretary-general of the World Meteorological Organisation (WMO), convener of the conference, told over 2,000 climate scientists, sectoral experts and decision-makers.

“Climate services” is the long-distance cousin to weather services or weather forecasting. New technology and better climate science has opened the window to very long range forecasting of climate events like droughts weeks and months in advance.

This year, scientists were able to anticipate unprecedented flooding of the Red River Valley in the United States Midwest months in advance, enabling local communities to prepare and avoid the worst consequences, said Jane Lubchenko, a noted ecologist, administrator of the National Oceanographic and Atmospheric Administration (NOAA) and head of the U.S. delegation.

“Imagine farmers able to determine what to plant and where, based on drought forecasts three to five years in the future, or coastal communities able to plan for sea level rise and storm intensity,” Lubchenco told IPS.

The proposed Global Framework for Climate Services will “strengthen production, availability, delivery and application of science-based climate prediction and services”.

The Arctic — The Earth’s Freezer — Is Defrosting With Dire Results

GENEVA, Sep 2 (IPS)

The rapidly warming Arctic region is destabilising Earth’s climate in ways science is just beginning to comprehend.

The entire world is being affected, and without urgent action to cut emissions, a too-warm Arctic could trigger catastrophic, irreversible climate change, top scientists say in a report released Wednesday in Geneva.

“It is crucial to know the full consequences of the Arctic warming, and this is an unprecedented review of the latest science,” said Martin Sommerkorn, an Arctic researcher and senior climate change advisor to World Wildlife Fund International.

“Simply put, if we do not keep the Arctic cold enough, people across the world will suffer the effects,” Sommerkorn told IPS.

Sea level rise of more than one metre, flooding affecting one quarter of the world’s population, and extreme global weather changes are on the way at the current pace of unchecked carbon emissions, the “Arctic Climate Feedbacks: Global Implications” report warns.

A warming Arctic has far wider and more serious consequences than previously believed based on the latest science of the past three years, including the very recent research from International Polar Year 2008-2009.

“There is a large potential that a warming Arctic will make climate change far worse,” said Sommerkorn, who acted as editor of the report written by 10 of the world’s leading climate scientists. Continue reading →

Ozone Treaty May Hold Key to Halting Climate Change

UXBRIDGE, Canada, Aug 25 (IPS)

Will the world take the easy step to phase out “super” greenhouse gases – hydrofluorocarbons (HFCs) – using the existing Montreal Protocol ozone treaty?

Doing so would be equivalent to preventing the release of 118 to 224 billion metric tonnes of carbon dioxide by 2050, according to a report by the Environmental Investigation Agency.

That’s vitally important.

The latest science shows humanity cannot put more than another 700 billion tonnes into the atmosphere over the next 40 years without risking dangerous climate change. At current rates of carbon emissions, that limit will be exceeded in half that time.

“An HFC phase-down under the Montreal Protocol will do far more for climate protection than the Kyoto Protocol has accomplished in its entire history or than Copenhagen will achieve in the next decade,” said Samuel LaBudde, senior U.S. climate campaigner for the non-profit Environmental Investigation Agency (EIA).

“And it will do so at a fraction of the cost of securing reductions in other sectors and much faster as well,” LaBudde told IPS.

The leaders of the U.S., Canada, and Mexico committed to “work together under the Montreal Protocol to phase down the use of HFCs” earlier this month at the North American Summit in Guadalajara, Mexico. This follows a similar commitment made by G8 leaders in July.

Primarily used in refrigerators and air conditioners, HFCs are the standard replacement chemicals for those that were thinning the protective ozone layer in the upper atmosphere. Although HFCs pose no ozone risks, they typically have a global warming potential hundreds or even many thousands of times greater than carbon dioxide (CO2), hence the “super greenhouse gas” label.

The number of the world’s estimated 1.5 -1.8 billion refrigerators, 1.1 billion home and 400 million mobile (auto) air conditioners is expected to grow dramatically as developing nations like China and India modernise and increase use of HFCs.

A July study in the Proceedings of the National Academy of Sciences reveals that such a skyrocketing use of HFCs will have a significant impact on the climate at projected growth rates by 2050, negating much of future efforts to reduce carbon emissions.

“Phasing down HFCs under the Montreal Protocol is a brilliant strategy,” said Durwood Zaelke, president of the Institute for Governance & Sustainable Development, an international environmental NGO.

“This is the treaty that never fails to deliver. It’s already phased out 96 chemicals by 97 percent, and it’s ready to tackle these super greenhouse gases,” Zaelke said in a release.

Two small island nations, the Federated States of Micronesia and Mauritius, were the first to campaign to amend the Montreal Protocol to tackle HFCs at a July meeting of signatories. Ironically, under the Protocol, richer countries provide financing to poor countries to replace ozone-destroying refrigerants with HFCs.

Many country delegates felt it is the responsibility of the Montreal Protocol to prevent the further commercialisation and prolific use of HFCs even though it is not an ozone-depleting chemical.

“The support of North American leaders is appreciated,” said Ambassador Yosiwo George from the Federated States of Micronesia. The tiny Pacific island nation is threatened by rising sea levels from global warming and is advocating for a 90 percent HFC phase out by 2030.

Early Warning Systems for the Coming Climate Storm

GENEVA, Aug 31 (IPS)

Climate change is here. The challenge in Geneva this week is to find ways to help the world cope with a climate that will have more and worse extremes in terms of temperatures, floods, and storms.

More than 2,500 experts and policy-makers from 150 countries are attending the Aug. 31-Sep. 4 World Climate Conference to discuss how to improve weather forecasting and long-range seasonal weather projections, especially to help poor nations in areas such as agriculture.

“Until now, the way that we deliver climate information to some sectors has been ad hoc. What we need is a formal system that all people can trust to access vital information that can save their lives and protect property and economies,” said Michel Jarraud, secretary- general of the World Meteorological Organisation (WMO), which is convening the World Climate Conference this week in Geneva.

The WMO has proposed that a global climate services system be created to boost observations and research for monitoring the climate and new information tools that will provide sector- and regional-specific products and services, Jarraud told IPS.

The first two “World Climate Conferences” in 1979 and 1990 were organised by the WMO and played the key roles in the creation of the U.N. climate secretariat, and the Intergovernmental Panel on Climate Change.

This “Global Framework” system could help reduce losses caused by extreme weather and climate events such as heat waves, sandstorms, cyclones, drought and floods which will become more frequent and more intense as the climate continues to warm, he said.

“Extreme weather events and changing climatic conditions affect all of us, frequently resulting in humanitarian disasters and heavy losses,” said Swiss President Hans-Rudolf Merz.

Marine trash, mainly plastic, is killing more than a million seabirds and 100,000 mammals and sea turtles each year, said U.N. Secretary-General Kofi Annan in a statement.

Plastic bags, bottle tops and polystyrene foam coffee cups are often found in the stomachs of dead sea lions, dolphins, sea turtles and others. The implications have many at the conference concerned. Last April, Dutch scientists released a report on litter in the North Sea and found that fulmars, a type of seagull, had an average of 30 pieces of plastic in their stomachs.

In the sea, big pieces of plastic look like jellyfish or squid, while small pieces look like fish eggs, says Bill Macdonald, vice president of the Algalita Marine Research Foundation, a Long Beach, California-based nonprofit environmental organization.

Macdonald, who is also an underwater filmmaker, said he has seen albatross parents fly huge distances to feed their young a deadly diet of plastic bottle caps, lighters and light sticks.

“The sheer volumes of plastic in oceans are staggering,” he said. In recent years Algalita researchers have sampled a huge area in the middle of the North Pacific, and found six pounds of plastic for every pound of algae.

VIENNA, Jun 29 2009 (IPS)

“So who here thinks there will be a meaningful deal in Copenhagen?”

Few of the more than 600 energy ministers, officials and experts from 80 countries attending the Vienna Energy Conference raised their hands in response to the conference moderator’s question about the final round of climate negotiations this December in Copenhagen.

“I don’t think there will be agreement on an emissions cap,” said Andre Amado, Brazil’s vice-minister for energy, science and technology.

Greenhouse gas emissions from the burning of fossil fuels must peak between 2015 and 2020 and then decline to prevent dangerous, irreversible climate change, scientists have warned. A strong international agreement on emissions targets for both the industrialised and developing world is widely believed to be the only way to ensure emissions peak and then decline.

“There will be agreement on technology transfer and reducing barriers for technology transfers,” to assist developing countries in cutting their emissions and adapting to the changing climate, Amado told participants last week in Austria’s capital city.

Desperately Seeking Leadership on Climate

Civil society will have to provide unrelenting leadership if  global carbon emissions are to peak in less than 10 years and go ‘negative’, experts say.

By Stephen Leahy

UXBRIDGE, Canada, Jan 15 2009 (IPS)

Global emissions of carbon dioxide must reach a peak in less than 10 years and then begin a rapid decline to nearly zero by 2050 to avoid catastrophic disruption to the world’s climate, according to a new report.

Emissions of carbon dioxide will actually need to “go negative” – with more being absorbed than emitted – during the second half of this century, according to “State of the World 2009: Into a Warming World” released by the U.S.-based Worldwatch Institute this week.

“2009 is a pivotal year to deal with climate change,” said Christopher Flavin, president of well-respected Worldwatch Institute (WI), a U.S.-based environmental think tank.

“Humanity will face grave danger if we don’t move forward now,” Flavin told IPS.

Climate change is happening faster and with larger impacts than previously predicted, concludes the 26th annual “State of the World” report, devoted entirely to the challenges and opportunities of global climate change.

Even an additional warming of 2 degrees Celsius poses unacceptable risks to key natural and human systems, warned climate scientist W.L. Hare, one of the report’s 47 contributors.

Content Control: Patents Threaten Traditional Knowledge of Indigenous People

“To have potatoes, there must be land, people to work it, a culture to support the people, Mother Earth and the mountain gods…”

VIENNA, Jul 6 (Tierramérica)

Indigenous peoples risk losing control over their traditional knowledge if the World Intellectual Property Organisation (WIPO) insists on strict standards for managing access to information.

Patents and other forms of restricting access to knowledge are very worrisome in a time of climate change, says a new report by the London-based International Institute for Environment and Development (IIED).

The study was presented at meetings of the WIPO – a United Nations agency – held Jun. 23-Jul. 3 in Geneva.

“Intellectual property standards restrict use of genetic resources when we need flexibility and adaptability to cope with climate change,” said Michel Pimbert, director of IIED’s Sustainable Agriculture, Biodiversity and Livelihoods Programme.

WIPO aims to develop rules for protecting rights over traditional knowledge, such as indigenous knowledge about medicinal plants, which conventional intellectual property laws do not cover.

However, according to IIED’s Krystyna Swiderska, who coordinated the research in Africa, Asia and Latin America, “WIPO’s call for consistency with existing intellectual property standards is a flawed approach as these have been created on Western commercial lines to limit access to inventions such as drugs developed by private companies.”

Intellectual property is about restricting access, creating monopolies and eliminating competition, and it is being pushed by transnational pharmaceutical and seed companies, said Pimbert. Continue reading →
