Greenland's ice caps are melting faster than predicted - and local farmers couldn't be happier. Thanks to rising temperatures, they can now grow new crops and raise cattle for the first time since the Vikings. Warmer seas are bringing huge catches of cod and growing seasons are up to a month longer.

"A little bit of extra warmth is good for us", states agricultural consultant Kenneth Hoegh. "We're growing things we would have hesitated to grow in the past".

But not all farmers are happy as the environmental balance becomes increasingly precarious.

Each year an estimated 2 million women and children are tricked, beaten, raped and forced by threat of death into the world's growing sex industry. "Trapped: Part One" followed Anna and Joy as they helplessly resisted being forced into prostitution on the streets of Europe. In this, "Trapped: Part Two", we follow them home to Nigeria, ruined and ashamed. We also get a rare glimpse of how desperate families are tricked into giving up their children to strangers from Europe who promise them riches, then sell them as sex slaves.

Papua New Guinea is facing a crisis of the young and innocent. The country's morgues are filling up with tiny abandoned corpses. For every one thousand babies born in PNG, more than seventy will die before their fifth birthday. "We're hitting our head against a brick wall" says one distraught community worker. But some unsung heroes are giving the babies dignity in death and teaching young women about the threat of disease and malnutrition.

"You can run, but you can't hide" say the girls, who night after night sell themselves to an endless stream of men. They ply their soulless trade in filthy brothels or parked cars. This film captures first hand the violence and eeriness of life working on European streets for young African women and girls who were tricked into leaving their villages with promises of a better life. Michelle Mildwater specializes in trauma. Her exceptional sensitivity allows two women - Anna and Joy - to tell their horrific stories. In "Trapped: Part One", we hear their tales of life on the streets of Europe. "Trapped: Part Two", seen at the same times next week, follows their shameful deportation home.

We've heard a great deal about the effects of climate change. The Carterets in the Pacific could be the first islands in the world to disappear due to rising sea levels blamed on global warming. "Our houses are getting closer and closer to the sea", complains one woman. "Maybe one day, a tidal wave will sweep everyone away".

It's estimated that the Carteret Islands will be completely submerged by 2015. Already, the beaches are littered with fallen trees, their roots eroded by the tide. Rising sea levels have made it impossible for the islanders to grow anything apart from coconuts. They are now dependent on aid from Papua New Guinea, which plans to relocate residents from the island. Some though, refuse to move. As one states; "If the island is lost, I'm lost too".

The situation in Afghanistan steadily deteriorates. In the past 12 months, thousands of Afghans have been killed and clashes between NATO troops and insurgents are commonplace.

Six years after the US-led invasion, the rhetoric has changed. Soldiers no longer talk about wiping out the Taliban or hunting down terrorists. Now, the buzz words are tactics of counter insurgency.

"We have to look constantly at ways to do it better and do it differently", states Lt Col. Woods. His men appear exhausted and demoralized. At night, the temperature drops to - 30°c. Blizzards have grounded their helicopters but despite the extreme weather, troops from the US 82nd Airborne are heading out for a ten day patrol. "The Coldest Winter" follows them as they battle the elements and the tense environment.

Every night, 14 year old Said scrambles down a narrow shaft leading to a tunnel. He'll spend the next eight hours digging without a break. It's claustrophobic, difficult and dangerous work. He, like others in Gaza, is digging a tunnel to Egypt. The tunnels are used to smuggle everything from weapons for Hamas to basic household goods that are not available in Gaza's isolation. The tunnels are the only way to import goods into the territory.

"They're a gold mine!" states Said. But to his disgust, most of the profits go to other people. "We do all the work, then they swindle us," he complains. Once the tunnel is nearly ready, "other people will open it, do the trafficking and make more money than us."

The money that Said makes will support his entire family. But every time he goes into the tunnel, he knows: "You are digging your own grave."

Africa is in the grip of a medical crisis as its doctors are lured away by lucrative jobs in Europe. Malawi now only has one doctor for every 50,000 people.

"We are working under very difficult conditions. It's like we are in a war", laments Robert Lapyam Ayella, the only doctor at Mulanje District Hospital. He's one of the few African doctors who hasn't moved to the West, where they can earn 200 to 300 times more. Making matters worse, approximately 25% of Malawi's health staff are expected to die of HIV/AIDS in the next decade. Facing these problems, it's not surprising entire medical classes decide to emigrate to the West. As one expat Malawian doctor states: "I earn a good wage in England. Why should I go back to Malawi to suffer?"

For centuries, Eunuchs have been an important part of Indian society. But the elevated role they once held has now faded. Today they live in isolated communities, working as prostitutes and beggars. Life may be hard but inside the community of hermaphrodites and castrated males, there's a real sense of warmth and camaraderie.

'Harsh Beauty' follows the lives of Jyothi, Usha and Hira Bai, three Eunuchs who struggle for acceptance in a culture splintered by religion, caste and politics. Filmed over four years, this is a warm and poignant look inside this usually hidden group.

Decades after the world was shocked by pictures of Romanian orphans tied to their cots in squalid conditions, many children are still being held in old-style institutions.

Babies at the pediatric unit are unnaturally quiet. They've learnt there's no point in crying. "They have no affiliation, no stability," laments supervisor Dr Monica Nicoara. Previously, many of these babies would have been adopted by Western families. But foreign adoptions are now banned and authorities want to find Romanian families for abandoned children. However this new system has failed many of the country's most vulnerable. Ricardo and George ended up on the streets after their parents abandoned them. They've given up on the state and now take care of each other.

Bolivians once boasted that the Chacaltaya glacier was the world's highest ski run. But the skiers stopped coming in the late 1990's. That's because the place known by the Aymara Indians as "cold road" is melting-and fast. The glacier serves as the main source of drinking water for millions of people who live in the region. As ‘World's Untold Stories: Bolivia Meltdown' reveals, that tap could begin to run dry within just a few years. Glaciologist Edson Ramirez says, "It's a critical problem - it's the same problem for Peru, Ecuador and Colombia - all the Andes." Global warming is at least partly to blame says Edson: "We do know that the effects of human activities accelerate it and play the role of the catalyst in this cycle."

The civil war ended three years ago. But life in Liberia is still far from stable. That's where the peacekeepers come in. Some 15,000 U.N. soldiers and police officers are helping to ensure a brighter future for Liberia's 3.2 million citizens. As ‘World's Untold Stories: Liberia - Female Peacekeepers' reveals, one battalion in the capital Monrovia is actually all female-a big first for the United Nations. The unit of Indian women is making a real difference in a country where rape was a common weapon of war. As one peacekeeper remarks "Men lose their temper, but women rarely do". The unit is also helping to repair the U.N.'s tarnished image in Liberia, where male personnel were once notorious for abusing women.

Decades after Myanmar's (formerly Burma) military junta forced the Rohingyas into exile, their suffering still continues. Trapped in displacement camps, they survive on starvation rations in constant fear of abuse.

"My people are rotting", despairs one refugee. The Bangladesh government, classes the Rohingyas as illegal immigrants. According to the UNHCR, guards at the displacement camp are accused of forcing refugees into prostitution, extortion and stealing food. Thousands more live in slums along the Naj river without the basic protection of the UN. "We survive by collecting leaves and boiling them", states one woman. "No-one cares about us".

The flood of Iraqis to neighbouring countries has provoked the greatest Middle Eastern refugee crisis in 60 years. They live in cramped squalid conditions, in constant fear of being deported. In Jordan, hundreds of thousands of Iraqis are struggling to survive in the capital, Amman. No country will offer asylum to Palestinian refugees, also fleeing Iraq. These refugees are now stranded and stateless in border camps like Rweished. "Our only fault is that we're Palestinian", despairs Khaled. During summer, temperatures here reach 50ºc. In winter, they fall below freezing. Their tents are regularly ripped to shreds by sandstorms and people have reached breaking point. "Most of us here is sick. Everyone is suffering."

By some estimates, 40% of all construction in Europe is taking place in Spain. Marbella is at the centre of the building boom, but that boom could turn to bust. Marbella's local council stands accused of sanctioning illegal construction projects in exchange for bribes. More than 30,000 apartments originally approved by the council violate planning laws.

Since Marbella's case broke, dozens of similar cases have been discovered across Spain in what has become one of the country's biggest scandals in years.

Capture means certain death. So why do some defectors risk it all to escape from North Korea? World's Untold Stories brings viewers the extraordinary story of the Park family, who cross borders and dodge checkpoints to make it to freedom. "Escape from North Korea" follows the Parks as they make their dangerous exodus into an uncertain future. The documentary also explores the hidden network of people who help North Koreans escape from Kim Jong Il's brutal and repressive regime-a regime that's now building a wall along the Chinese border to deter defectors.

"I always wanted to be a stuntman", explains one of a growing number of disaffected youths that ride on top of speeding trains for a quick thrill.

Hundreds of people have been killed ‘surfing' the trains - dancing, ducking bridges and hanging from the sides. Most of the Soweto surfers come from broken homes in the impoverished South African township, spending their days drinking, smoking and performing their acrobatics.

This stark documentary tells the story of a member of Islamic Jihad who became an informant for Israel. He operated inside one of the group's suicide bomber cells, reportedly providing intelligence that led to an Israeli strike against Islamic Jihad leaders. Later, his identity is discovered.

The producers of "Love and Betrayal in the West Bank" gained remarkable access to film inside the Islamic Jihad movement, providing rare insights into its operations in the territory.

The southern Philippines is a hotbed of terrorist activity. Jamaah Islamiah, Abu Sayyaf and Al Qaeda all operate in this troubled territory. To combat the growing threat, a heavily armed anti-terrorist unit operates in the shadows, weeding out Jihadist networks and launching daring raids to arrest or kill the operatives.

Police Chief Lito has led the unit for 18 years. He's received a tip-off. As the unit moves in a shot rings out. Lito's informant has been hit. The next day another raid. Another colleague is gunned down. "I am fighting the grasp of terrorism here", he says. This documentary provides extraordinary access to the fight against terrorism at the ground level.

The monumental statues known as the Buddhas of Bamyan became a symbol of Taliban tyranny when they were destroyed in 2001. Now there's a symbol of how drastically things have changed in Afghanistan. The province of Bamyan is home of the country's first and only female Governor. Habiba Sarabi is trying to carve out a new Afghanistan by sending girls to school and persuading farmers to give up their opium crops. Her success however is offset by the daily struggles of the country's other prominent female politician. Outspoken Member of Parliament Malalai Joya lives under constant threat of assassination. Her speeches are frequently interrupted and other politicians have called for her to be raped. But she remains defiant. "I accept these risks because of my people."

"I can't think of many police who have to face RPG's and mortar rounds on a daily basis". Gary Bullard, director of police training.

When will Iraqis police themselves? This is a question that has become hotly debated in the corridors of power, but what of the police recruits themselves? Every six months the equivalent of an entire training class of 1,500 Iraqis is wiped out. Yet recruits continue to sign up, many of them desperate for the money.

The Very Thin Blue Line takes us inside a police training camp in Jordan where the instructors focus on one skill in particular - survival.

We see disturbing pictures from Iraq on a daily basis. Reporters reporting. Politicians talking. But what about the ordinary Iraqis who struggle to earn a living, keep the family unit intact and simply survive from one day to the next? "Baghdad Blogger" Salam Pax takes an insightful and sometimes irreverent look at the daily travails in two reports: "How to Stay Alive in Iraq" and "How to Have Fun in Baghdad".

To some Christian groups in the United States homosexuality is not only a sin, it's a mental disorder. As such, they feel it can be cured. More than 100 camps have been set up to administer "re-orientation therapy" with the intention of turning gay people straight. The programs are big business and highly controversial. Those running the camps say they have a 30% success rate. Opponents believe re-orientation therapy is dangerous, sometimes leading to attempted suicide by those who feel that they have failed God.

It doesn't glitter like a diamond or burn like oil but cassiterite is another natural resource that is causing more pain than profit for the majority of Africans that try to extract it from their soil.

 
Demand for cassiterite - a tin ore used in computer circuitry - is on the rise. So too is illegal mining of the ore in the Democratic Republic of Congo where militias are forcing laborers to work in atrocious conditions with little or no pay.

 
Reporter Jonathan Miller treks deep into the jungle to see how it works.

Afghanistan has been torn apart not only by war, but also drugs. The country is the world's largest opium producer, feeding the insatiable appetite of heroin addicts far from its borders. But there are addicts at home as well. Reza and Hussein are brothers that live in squalor in Kabul's Old City. Heroin has drained them in every sense, making them outcasts in a society that cannot afford rehabilitation programmes. Their only hope to kick the habit lies in Kabul's Mental Health hospital where screams from electro-shock therapy can be heard in the corridors. Yet the brothers are determined: "If you ever see me in any of the drugs dens again, shoot me" says Hussein.
