broadcast on pbs in america and around the globe. coming up later, a tribute to a soldier who died in a line of duty. a special report on atropos last operation in afghanistan. all aboard the science express -- germany set out to train and to generation of scientists. >> it is by no means the final deal on climate change, but nobody expected that. president obama describes the new agreement from the world's richest nations, the g-8, as a historic consensus. the world's major economies have taken a major stride. the industrialized world and the biggest developing economies, led by india and china, are committed to restrict emissions.

it's a signal of intent. the progress from here will not be easy. from the summit in italy, we have this report. >> some of the most powerful politicians on the planet. an impressive force, but are they at to solving climate change? it's one of the most pressing issues of our time. the g-8 leaders have agreed to targets, but without india, china, and brazil, will the plan work? >> we do not expect to solve this problem in one meeting or one summit. we have made some important strides toward. >> the new deal makes one -- made once a vague goals more definite. a limit on the rise in temperature to no more than 2 degrees celsius. for that to happen, by 2050, rich countries would have to cut emissions by 80% to read part of

the plan to cut overall emissions in 2050 by 50% treed but that is more than 40 years away. countries need to be cutting faster than that. in a sharp rebuke, the un secretary general says the plan is not ambitious enough. >> the policies they have stated so far is not enough, it is not sufficient enough, to meet the target. this is politically and more police -- politically and morally and imperative and a historic responsibility. >> barack obama is a welcome addition to the extended family of the g-8, after george did the bush's foot-dragging on climate change. if many of the non-g-8 leaders have been skeptical of the plan, applauding the lid on temperature rises, but reluctant

to tie their fast-growing accompany -- economies too deep division cuts they say they can't afford. there is broad agreement that climate change is an urgent problem, partly mannai, and the world has to find a way to tackle it. -- partly man made and the world has to find a way to tackle it. it is a reminder that not all disasters are man made -- there was a tour of the earthquake damage. it was a glimmer of glamour amidst the ruins. >> ak issue in the debate on climate change is the debate of tropical rain forests. it is estimated deforestation produces one fifth of all gasing image -- all gas emissions. donna has now lost most of its forests. our environment correspondent has this exclusive report.

>> a unique view from a tree that is about to be felled. in the heart of the forest, bloggers are showered with sawdust. this operation is legally, but many are beyond the law and donna has lost most of its forests. -- ghana has lost most of its forests. so another massive tree taken away to be used for timber. this process is going on not just in,, but in tropical rain forests from the world. -- not just in ghana but around world. the question in this poor country is how to stop it. >> ghana needs of the trees.

it needs the money. but the environment must be protected and kept intact. >> here is a possible solution. in what used to be forests, new trees are being planted. 1 million so far. they should make money by absorbing carbon dioxide. >> knows seedlings will grow rapidly and contain vast amounts of carbon dioxide. there is a huge market of individuals and companies who will pay for this project to be implemented by buying carbon credits. >> so how does this work? take my journey here. it has made me responsible for one and a half tons of carbon dioxide in it from the airplane. i can offset that by paying this project which is planting these trees. this one will grow over the next 8-12 years and absorb my one and half tons of carbon dioxide.

it's a small start, but it could be big business. the aim, if you can picture it, is for the biggest polluters, thousands of miles away in the developed world, to help pay for the forest. it's a controversial idea. as the seedlings are prepared, environmental groups are critical. they say that rich countries should cut pollution themselves. >> it is fundamentally wrong for developed countries and consumers to shift responsibility of mitigating the effects of climate change to developing countries. he >> but all of the time, the logging goes on. it is more tightly controlled here than anywhere else in africa, but is hazardous work. there is one major worry -- can the planting ever be faster than the selling?

-- the falling. >> one small australian town has taken a step to save the environment by banning bottled water. 355 residents voted for this change. the alternative will be specially designed, reusable bottles which are found -- bernard madoff has decided not to appeal against his 150 years sentence according to his lawyer. the 71-year-old was sentenced at the end of june. he pleaded guilty in march to 11 counts related to billions of dollars in investment fraud. south korea is suffering a second day of a suspected sniper attacks, paralyzing several major web sites. -- cyber attacks.

some reports suggest north korean involvement. police in iran have broken up demonstrations in the capital and major provincial cities. it has been the biggest in 11 days, defying government warnings that street protests would be crushed. eyewitnesses report police firing tear gas. iraq has seen its worst day of violence since american forces completed their withdrawal from urban areas just over one week ago. two suicide attacks in the north claimed at least 34 lives. in baghdad, two bombs went off in the market, killing nine. we have this report from baghdad. >> a double suicide bombing in northern iraq. the two blasts came within moments of one another. the first targeted an official

in security services, killing him and members of his family. when people rushed in to help, the second bomber blew himself up, killing many bystanders. one hour later and to the south, in a poor shiite area of baghdad, two bombs exploded in a crowded market. not suicide attacks, but the results were the same, yet more dead and still more wounded. much of the violence in recent weeks has been in the north of the country. on wednesday, two car bombings near shiite mosque claimed at least 14 lives. but the bombings and shootings have not been confined here. there were other violent incidents across the country, bringing the death toll to well over 40. at the end of last month, u.s. forces completed a gradual process of withdrawal from iraq 's street, amid much

celebration. the americans are aiming for a full military departure from iraq by the end of 2011. last week's ceremony marked the first steps on that road. today's bombings will inevitably raise the question of love -- was the pullback premature. what appears to be happening now is that insurgents, those who want to derail the hand over process from u.s. forces to iraqis seemed to be testing the ground and seeing how capable the iraqis are of maintaining security on their own. >> in afghanistan, 13 primary school students are among 25 people killed by a bomb on a road south of the capital. it was so huge that pieces of the vehicle carrying the explosives were found more than a kilometer hand -- a kilometer and a half away. 24 hours ago, with great dramatic images of british troops fighting the taliban in

afghanistan. the british death toll in afghanistan is now 176. the latest casualty was a 20- rolled tripper in the light dragoons had hoped to represent britain in debt -- in the olympics. our correspondent was on patrol with his group shortly before he died. >> this is some of the most intense fighting ever experienced by british troops here. >> they have battled the taliban for years and still they keep coming. many soldiers have been wounded and if you have paid the ultimate price. like this trooper on the right. we met him and his mates on the front line. he was killed two days ago.

he was the victim of a roadside bomb. they are the greatest danger facing troops here. every soldier fears of what might lie in the ground beneath. now there are questions about whether they have been well protected. >> we are putting in our -- we are putting our soldiers into impossible positions. half in, half of strategy, medellin along. either give them the commitment to support -- it is also providing them with the right political strategy. >> british troops could undoubtedly benefit from the extra resources. reserves have had to be called again. the truth is that the u.k. on its own cannot win the battle here. it will take injections of thousands of extra forces. they have arrived in the shape

of u.s. marines. the question is whether the combined effort will make a difference. this has already been a grueling few weeks in the operation. every step, every journey runs the risk of death from roadside bombs. a vehicle damaged in an explosion is removed from the front line. the british army and its men are now being tested to the limits. >> stay with us if you can. coming up, the british newspaper in trouble for allegedly tapping the phones of celebrities. first, the city, the capital of xinjiang is still tense and divided after days of ethnic unrest. chinese security forces are patrolling the streets in huge

numbers to prevent more violence between the uighur and han communities. if foreign spokesman says jain had proof of some of those involved in the unrest had links to al qaeda and other militant groups. >> we have come to possess a great deal of evidence proving these people received training from foreign terrorist groups, including al qaeda. they are linked with vicious forces from abroad. in this respect, we continue to urge nations to strengthen cooperation to maintain peace together and safeguard china's stability and peace. >> a bbc correspondent is one of the few foreign journalists in the region and he sent this update. >> here on the han chinese side of town, people have welcomed the troops. these men are marching with a banner thanking the security

forces. they're bringing supplies of fresh water. the troops are lined up along the street. you can see them on all sides. you can even see them at the end of the street if we turn around. as they're walking past, the troops are thanking them and giving rounds of applause. just over there, that's the uighur neighborhood. people there say they still don't feel safe and are worried about the security forces and the threat of vigilante groups of han chinese. >> of the foreign minister of china says it has sufficient evidence that four employees of rio tinto who are being detained stole state secrets. one of the man is an australian national. this is a bbc world news. the latest headlines this hour -- @ d g-8 meeting in italy, president obama says a historic

consensus has been reached to ensure stopping global warming. not everyone is sure. the british press has a represent -- has a reputation for being the toughest in the world. the most irresponsible, some would say. how far you go to get a story? that's the big question in london. allegations surfaced that thousands of celebrities and politicians have had their self contact into illegally by private detectives working for a mass-selling sunday tabloid. we have this report. >> at the heart of this scandal is the allegations the and "news of the world" routinely listen to people's voice mail messages. there were leading politicians and the celebrities. until today, the scale is unclear. now, the "guardian" newspaper says thousands of mailboxes were hacked into and it million

pounds were paid to keep quiet. >> what is the -- it appears that this has been going on -- it looks almost casual. >> it seems the culture of the newsroom was on any story, let's get a private investigator and listen to his phone and voice mail and see what we can get. fishing expeditions of no public interest. >> what the "news of the world did" was caught people's phones when they would be off and not be answered. it happened to the voicemail using a pen code. how did they know what the code was? most people don't bother to change the number from the one set by the mobile phone provider. the royal editor @ "news of the world" was prosecuted for hacking voicemail along with a private investigator. no one else was. today, scotland yard was

standing by. >> our inquiries show that in the vast majority of cases, there was insufficient evidence to show hacking had been achieved. where there was clear evidence, that funds had been tapped, their contact by police. >> the importance is magnified because the editor of the "news at the world" at the time is the director of communications of the conservative party. the scandal is a toxic mix involving britain most powerful newspaper group, allegations of serious criminality, and a fevered atmosphere of westminster for less than one year to go until the next general election. >> investigators are scaling down the search for flight recorders from the air france plane which crashed into the atlantic over a month ago, killing everyone on board. even the french navy submarines have not been able to detect signals from the black boxes.

the cause of the crash now may never be established. the former u.n. secretary general has given the international criminal court a list of kenyan leaders suspected of orchestrating violence in the country in 2007. more than 1000 kenyans were killed in clashes between supporters of the two presidential candidates. international conservation groups say rhinoceros' poaching in africa is at its highest level in 15 years. the rhino populations are seriously threatened. at least 160 rhinos were illegally killed in south africa and zimbabwe last year. still to come on bbc world news, a futuristic journey -- how germany is trying to capture the imagination of a generation with a train. first, pakistan's religious schools are often targeted by critics for promoting a radical view of islam. it is a criticism that pakistan

the government is key to dispel. they invited the british foreign secretary to the debt -- to visit a school there. >> the religious schools here, children spend several hours reciting the koran to learn every word. in this one, they try to do more -- learning conventional school subjects as well. they are against violence and in favor of a girl's being educated. >> de want -- they want to prove to be good students and know about other subjects. [unintelligible] >> is not the kind of education british ministers are accustomed to visiting. some of the schools have inspired groups like the taliban. but many of the religious teachers to run the mosques in

britain went to the school. understanding what this education is about could give the government more understanding of muslims in britain and how to tackle fundamentalism on its own terms when it turns violent. >> we've seen young people memorizing the koran. we have seen a great devotion to religious teaching. i think the test for all of us is the enlightened mind and to make sure the citizens growing up here want to be productive citizens in the wider world. >> pakistan as a country struggling for its identity in the bottom world. the fight is on, not just against the taliban, but for the hearts and minds in every street in the country. that's what makes education so important. >> fewer and fewer students are interested in studying scientists at the university. it's a problem facing countries

across europe. but the germans have come up with an unusual way to hook a younger generation. they're using a train they call the science express. >> attention please, attention please. the train now standing on a platform eight is the science express. next stop, the future. >> so here i am on board the sides express. as you can see, this is no ordinary too few trained. it's a traveling exhibition packed with gadgets and gizmos and the latest in german technology. the train travels across germany, stopping at towns and cities along the way. it tries not only to get the public interested in science, but to get people thinking about the big questions of life, the universe, and the future. for example here is something i never knew before -- in the future, everyone will have one of these things. a mood recognition machine. i find the idea unnerving, but

look at that. just by looking at you, this can't tell whether you are happy or surprised or angry. this part of the train highlights one of the biggest challenges facing the planet -- as you can see from the numbers appear, the world's population is rising by the second. but at the same time, the amount of available farmland is falling. so the question is, how can we feed the planet in the future? further down the carriage, they have a possible solution. multi-storied farms growing crops skyscraper style could be the way forward. i have to say i've never been on a train with birch trees before. but this is the environment and energy carriage. one of the things they talk about here, they talk about using renewable energy. let me show you an example. look at these solar panels.

the idea is you could sew them onto your jacket or shirt so you could charge for mobile phone or music player while you walk down the street. if the sun is shining. look at what i have made in the experiments cabinet with a live ball, a solar panel and a few wires. a brush that walks around the table. that's useful. i have learned a lot about the future on this train, but the science expressed also teaches how little we know about the past and the origin of our own planet. the message of this carriage is we only know 4% of the universe. that's a sobering thought and it's also time for a break. all this science is making me sleepy. if you don't mind, i will crawl into this futuristic football and listen to a german scientist tell me about solar system.

>> finally, the annual craziness and the spanish town of pamplona. five people have been enters -- have been injured in the traditional running of the bulls. people come all the world for this test of bravery. it was a very fast run this time, lasting only 2 minutes 20 seconds. there were five runners removed to hospitals for treatment. thank you for being with us. >> bbc world news was presented by kcet in los angeles. funding was made possible by the freeman foundation of new york, stowe vermont, and honolulu. the newman's own foundation and the john d. and catherine t. macarthur foundation. macarthur foundation.
