Rain threatens Myanmar survivors





Survivors of Cyclone Nargis in Myanmar are facing a new threat from heavy rains that could cut off aid completely, forecasters and aid agencies have said.

The warning comes as the International Federation of Red Cross and Red Crescent Societies estimated the toll from the cyclone to be between 68,833 and 127,990, far more than the government's revised toll of 38,491 dead and 27,838 missing.

The United Nations also increased the number of people severely affected by the cyclone on Wednesday, saying up to 2.5 million people urgently need water, food and shelter.

Earlier fears that a fresh cyclone could hit the disaster area have abated.

But with the weather system expected to dump up to 12cm of rain on the region over the next six days the Red Cross has said that already struggling aid deliveries could halt altogether.

The heavy rains are also raising the risk of flooding on areas of dry land where cyclone survivors have taken refuge.

On Wednesday the UN continued to push Myanmar's military government to expedite the entry of aid into the country, with Ban Ki-moon, the UN secretary general despatching his top humanitarian official to Yangon in the next few days.

John Holmes, the UN's under-secretary general for humanitarian affairs, will hope to persuade Myanmar's ruling military to open up to a full-scale relief effort.

The decision to send Holmes to Myanmar was announced at the end of a special meeting convened at the UN headquarters in New York to find ways of getting aid into Myanmar more quickly.

Speaking after the meeting Ban said diplomats were "encouraged" by the increasing flow of aid to Myanmar but urged its rulers to be "fully co-operative" in providing access.

Holmes urged Myanmar's rulers to make a "radical change" and allow in foreign aid workers to avoid a second wave of cyclone deaths, saying access was "the biggest problem we have at the moment".

And Louis Michel, the EU's humanitarian aid commissioner, said there was now a risk of famine, adding: "If there is a lack of access, more people will die."

However, Samak Sundaravej, Thailand's prime minister, said after a brief visit to Myanmar on Wednesday that the government had again ruled out allowing in foreign experts to help the relief effort.

"They insisted they can take care of their people and their country. They can manage by themselves," he said.

But the head of the Association of South East Asian Nations (Asean), of which Myanmar and Thailand are members, said the military government had agreed to issue visas to one of its rapid assessment teams and Asean would take more of a lead in aid efforts.

'Don't write us off'

There is a consensus emerging now that Asean has to take the lead and Asean has risen to the occasion," Surin Pitsuwan, secretary-general of the 10-member group, told an audience at the Council on Foreign Relations in Washington on Wednesday.

The regional body has come under fire for failing to respond swiftly to the crisis.

Surin said he understood growing frustration at its slow response but added: "Don't just write us off yet."

He said many outsiders were "very anxious, very angry and very frustrated, and you have the right to be. But Asean needs encouragement. Asean needs less of the criticism … less of the ridicule."

"We are trying to work around a very, very strict resistance and mentality and mind-set that have been there for a long, long time," he said.

The group is due to meet on Monday in Singapore to discuss help for Myanmar. Ban Ki-moon, the UN secretary general, has said he is appointing an official to liaise with Asean on aid efforts.

Tonnes of international aid is flowing in to Myanmar but aid groups warn a lack of infrastructure and heavy equipment means not nearly enough is reaching the southern Irrawaddy delta.

Much of the aid that has been cleared to land is reportedly still at Yangon airport.

Nargis Cyclone Hits Myanmar Aquaculture Industry

MYANMAR - The recent cyclone in Myanmar (Burma) is expected to severely hit the country's agriculture and aquaculture industries.

The five states that have been affected own 80 per cent of the country's fish aquaculture ponds and 26 per cent of the shrimp aquaculture ponds. Fish and shrimps might have escaped from the ponds if flooded by water.

The five states also produce 65 per cent of the country's rice, and have about 50 per cent of all irrigated areas. There is risk that stored rice seeds kept by farmers - usually under poor storage facilities - might be affected by the cyclone.

Some rice crops under irrigation might be affected if not yet harvested.

Rubber plantations in five affected states cover 20 per cent of national total. However, most rubber trees are relatively young and might also be affected by the cyclone.

The five affected states are famous for livestock production - having roughly 50 per cent of national poultry production and 40 per cent of pig production. FAO also expects problems for small scale livestock holders to treat injured/sick animals or feed surviving animals.

FAO/WFP is to carry out joint assessments of food needs, damage and needs assessment in the agricultural, livestock and fisheries sectors as well as looking at livelihoods and natural resource issues in the most affected areas.

UN clusters are leading the action, and the UN - including FAO - is examining the need for a flash appeal, Relief Web said.

Together with the government, UN partners and donors, FAO is ready to undertake on the spot detailed damage assessment – and formulate measures to protect farmers from further losses and provided immediate support to recover rural livelihoods.

Artificial Energy Islands Could Power The World

Artificial Energy Islands Could Power The World

Ocean waves are already being used as a source of renewable energy, but could differences in water temperatures in the sea be our next source of green power? A decade old idea to generate renewable electricity for the globe with offshore, floating ‘Energy Islands’ could soon become a reality. The concept - creating artificial islands to collect wind, wave and solar power in the tropics - is based on the work of Jacques-Arsène d’Arsonval, a 19th-century French physicist, who envisioned the idea of using the sea as a giant solar-energy collector.

Inspired by Jacques-Arsène d’Arsonval, architect and engineer Dominic Michaelis, his son Alex Michaelin (also an architect), and Trevor Cooper-Chadwick are developing a new technique called Ocean Thermal Energy Conversion (OTEC) that takes advantage of differences in temperature between the ocean surface sea (up to 29°C in the tropics) and water a kilometer down (which is typically 5°C). Here’s how it works: warmer surface water is used to heat liquid ammonia, converting it into vapor, which expands to drive a turbine — which in turn produces electricity. The ammonia is then cooled using cold water from the ocean depths, returning it into a liquid state so the process can start all over again.

Their goal is to build a network of “energy islands”: floating hexagonal-shaped platforms of reinforced concrete and corrosion-resistant metals that would generate electritict via wind, wave, and solar in addition to having an OTEC plant. It’s estimated that each island complex could produce about 250MW, and that 50,000 “energy islands” could meet the world’s energy requirements (as well as provide two tons of fresh water per person per day for the entire world population — desalinated water is one byproduct of the OTEC process). OTEC plants work best when there’s a temperature difference of 20°C between water at the surface and the water below, making tropical and sub-tropical seas the best candidates for energy islands.

The concept will be launched later this year at Sir Richard Branson’s Virgin Earth Challenge, which offers $25 million in prizes for innovative solutions for combating global warming.

The best of the Google Earth and Maps

The best of the blog via Google LatLong by Kate on 12/23/07

Since the start of Google Lat Long back in May, we've had fun keeping you updated on all the exciting new developments in the geo world -- from product launches and innovative user-created content to the evolution of the geoweb in general. As the year comes to a close, we thought we'd take a moment to look back at some of the greatest moments in news and notes by the Google Earth and Maps teams.

Street View
Since the launch of Street View in May, our post introducing the service remained one the top five most read posts consistently throughout the year. And "street view" was one the most common search keywords. So just as we did earlier this month in announcing 8 new Street View cities, we'll be sure to keep you posted on new city rollouts.

Google Earth Outreach
We heralded the arrival of this exciting new program for non-profits with a post that pointed to video footage of our kick-off event at our New York office. The video featuring an appearance by Jane Goodall was viewed over 22,000 times.

My Maps and Disaster Relief
When the My Maps tab was added to Google Maps earlier this year, we were eagerly anticipating all the cool and creative custom maps folks would be coming up with. However, we were positively floored to find the incredible maps made to aid areas in need. From flood maps created by "citizen journalists" and by BBC Berkshire to the San Diego fire maps and the Google Earth layer of Southern California imagery, the astonishing number of views pointed to new ways to help.

Sky in Google Earth
Another top post of the year, our note introducing the addition of a new Sky view in Google Earth, caught the attention of many Lat Long readers. Google Earth aficionados are able to zoom in on distant galaxies and explore constellations and supernova explosions from the comfort of their computer screens. A list of great tips on how to use Sky in Google Earth for educational purposes followed, and you can expect more updates in the new year.

YouTube videos in Google Earth
Ever watched a funny, intriguing, or outrageous YouTube video and wondered where it came from? Well, we have too. That's why we were so excited to announce the addition of a new YouTube layer in Google Earth. Videos geotagged in YouTube are included in this browseable layer, making it easy to view clips associated with a location of your choice.

Maps Mania!

2007 saw the addition of a number of great new features in Google Maps, perhaps too numerous to count. Early on in the year, the creation of the My Maps tab and the addition of countless Mapplets enabled just about anyone to create their own mashups. Throughout the year, searching for accurate and helpful directions got a whole lot easier with the launch of draggable directions and the ability to read and write user reviews of businesses, as well as edit address markers. Finally, mapmakers enjoyed the addition of cool new Maps functionalities towards the end of the year, including the ability to both collaborate on customized maps and embed them wherever you see fit, as you might a YouTube video.

As you can see, this year's been a busy one. We're all looking forward to a few days of rest and holiday cheer. And with that, we must bid adieu -- happy holidays and a wonderful new year from all of us at Google Lat Long! Stay tuned for more geo news and notes in 2008, and don't forget to track Santa!

Oceans face the acid test


Acid oceans are the elephant in the room of global change – an event potentially so massive and profound in its implications for life on Earth that the world media has largely avoided it, governments shunned it and scientists discussed it mostly in muted tones, usually behind closed doors.

The acid oceans theory is quite straightforward: the CO2 emitted by human activity dissolves out of the atmosphere into the seas, gradually turning them more acidic. This is largely independent of global warming or other effects. It is a straight equation – about half of all the CO2 produced since the start of the industrial revolution has ended up in the sea, reducing the surface pH by 0.1 (some experiments indicate as much as 0.3 pH)
Ref: Science Alert

A further reduction of 0.5 pH to around 7.7 or lower is expected by 2100 if carbon dioxide continues to increase in the atmosphere at the predicted rate. The ARC Centre of Excellence in Coral Reef Studies’ Professor Malcolm McCulloch says it is now beyond question the oceans are becoming more acidic, and this is happening 100 times faster than at any time in recent geological history. “The reason this effect has snuck up on us is that we don’t have long term records for ocean acidity,” he explains. McCulloch and his team have recently developed a world-first way to measure past acidity in sea water.

The change in acidity may seem minor but experiments by the Centre’s Professor Ove Hoegh-Guldberg suggest it could be enough to shut down coral growth and kill the calcareous algae that hold together the fronts of reefs. He has warned that Australia risks losing the Great Barrier Reef if atmospheric CO2 levels rise above 500 parts per million from their current level of 385ppm, as they are currently expected to do by mid-century.

If that were not serious enough, an even more profound impact is likely to occur among calcareous plankton which will be unable to form their chalky skeletons as the water acidifies. The vulnerable corals and plankton make up about a third of all life in the oceans.

The most likely consequence of their loss or decline would be a massive realignment of marine food chains, reaching right up through fish and birds to land animals and humans. While other algae would probably replace those that perished, this would take time and would not necessarily preserve current fish and marine animal populations.

A second likely consequence of acid oceans is accelerated global warming, caused by the partial or complete shutdown of the oceans’ biological and physical carbon pumps, which extract CO2 from the atmosphere. This would leave more CO2 in the atmosphere to insulate the Earth and warm it more quickly.

In the short run, too, higher levels of dissolved CO2 in the sea also make it harder for fish and squid to extract oxygen from the water, and may kill those creatures with a high oxygen demand.

The worst-case scenario is that a mass death of sea life combined with heavy nutrient runoff from the land could lead to stagnant, oxygen-less seas where nothing but bacteria exist. These, ironically, are the very conditions thought to have given rise to todays’ mighty oil fields, such as those of the Arabian Gulf, which are one of the greatest sources of the CO2 we are pumping into the atmosphere.

Finally, many of the vulnerable marine creatures play a significant role as oxygen producers for the planetary atmosphere. The effect of their removal or reduction on our ability to breathe is not yet understood, but some researchers fear it could reduce the habitable biosphere.

About 251 million years ago the Great Dying at the end of the Permian took out 90 per cent of all sea life and 75 per cent of all land species. The causes are still debatable, but high CO2 levels released in a massive episode of volcanism in Siberia are one explanation. This may have produced acidic, oxygen-less oceans. Not long after, fungi were the dominant lifeform on the planet, dining on the carcases.

Today the scientific evidence indicates clearly that the surface oceans are already acidifiying, and the effects of this can be seen in corals and other organisms.

Australia, having the world’s largest coral reef – with the $5 billion industry and 60,000 jobs that hang off it – and being next to the Southern Ocean whose chilly waters provide the Earth’s main mechanism for pumping CO2 out of the atmosphere, has a larger stake in this phenomenon than other countries and should be putting maximum scientific effort into understanding it. It is not a trivial issue for any government or nation.

People did not believe the melting icecaps idea a few years ago but, if television has performed one good deed, it has been to bring the reality of polar dissolution into a billion living rooms. Finding out whether the burning of fossil fuels is killing sea life and how this will affect all life on Earth is even more important and urgent.

Will we soon be extinct?

Do you ever walk around with the vague feeling that you're going to die soon? That could be because -- according a recent study -- the Earth might be due for a catastrophic mass extinction.

Although it can't be shown as the direct cause, global warming like we're experiencing now has taken place during past mass extinctions.

has taken place during past mass extinctions.

Population ecologists -- scientists who study the relationship between species and the environment -- from the Universities of York and Leeds in Great Britain took a closer look at the fossil record recently. They found that, historically speaking, we're living in a climate that traditionally has seen the extinction of large numbers of species.
