measures. over a century ago the triangle shirt factory fire changed the political state of workers' rights. tonight in a deeper look - the state at play today. good to have you with us. foreign documents are being shipped out of yemen as saudi arabia intensifies air strikes against houthi targets. the united nations said it evacuated workers from sanaa. the area took numerous hits by the coalition air strikes, jets targeting a base operated by houthis as well as a military headquarters near the airport the air strikes today targeted houthi strongholds of sadr. despite the attacks houthis advanced on the saudi arabia border. tanks appear to be heading to

yemen. earlier it was indicated that ground troops may be needed in an operation against the fighters. thousands of protesters marched the streets in taiz expressing support. houthi fighters captured much of the city of taiz including the airport. the fighting in yemen dominated the summit. the yemeni president called on the fighters to surrender and return the country to stability. >> reporter: abd-rabbu mansour hadi gets the political backing he wants. a rare moment of agreement against arab leaders to curb the rise of shia houthi fighters. abd-rabbu mansour hadi is talking tough. >> translation: i call on you until the gang screned. leave the state institutions and

bagss. -- and bagss. leading the war, he says his country was forced to take actions. he is open to dialogue. >> translation: we wish we didn't have to take the decision. we stress that riyadh has to open the door to all parties that want to maintain security and stability, meeting under the umbrella of the g.c.c. rejecting the coup against it and stopping threats against regional countries. >> the saudis and other gulf and narrow states are nervous about the rise of iran. they fear the influence is creeping closer. closer by way of iraq in the north and support for the houthis in the south. air strikes are hitting positions on the other side of that border. joined by artillery from the south-east sides. fighter jets on saturday struck

multiple targets including command and control centers. the coalition says the strikes were precise. the houthis say the air raids killed dozens of civilians and children over the last four days. the president who left at the start of the campaign urged leaders to continue the strikes. >> translation: continuing dialogue is the next option to solve the problem and not the strikes. i hope arab leaders do not bet on a losing horse. you have tried that horse for four years. i call on you to take us to dialogue and elections. i urge you to have mercy on the people of yemen from the barbaric strikes. >> it could fall an deaf ears. it is accused of striking an alliance with the houthis to help them take over yemen. the fight took a twist.

the outcome could change the yemeni landscape and tip the balance of powers. >> the impact of the war in yemen is felt by people in the eastern country of djibouti where flights and air traffic has been disrupted. >> reporter: this is the port of djibouti. the crisis in yemen is proving a test for the country's claim to be a shipping hub. being the closest port to yemen djibouti is experiencing an increase in traffic. seven ships arrived, five oil tankers, and two container ships. >> we are assisting them with all the handling that they need in the port to dischargement goods and free the ships. it's costly to keep a ship waiting.

it can cost up to $50,000 a day. >> djibouti is close to a vital maritime corridor providing access to the red sea. with only 5km across at its narrowest poison it's the strait separating yemen from djibouti. nearly 40% of the trade is estimated to pass through the street. much of it on the way to and from the swiss canal. officials expect more ships diverted in the coming days and they have the capacity to handle the traffic. air traffic has increased. following the closure of yemen's air space flights from the carrier also moved it. these are some of the hundreds of passages stranded in djibouti. >> we came from egypt. we have sick people children and family. and have more than 20 people

that this surgery. we appeal to the gulf nation and president to return us home. >> they are preparing for an influx of refugees. they are preparing a place to hold up to 5,000 people. 180km from here. aid workers say the numbers could be higher than that as more than 200,000 refugees in yemen could flee back through djibouti following a major developing story in nigeria, technical problems forced a one-day extension of a presidential election since the return of diplomatic rule. the polls will remain open on sunday. on the ballot incoming president jonathan goodluck and retired general muhammadu buhari. voters faced violence from boko haram. 41 people were killed mainly in the north-east of the country. after a deadly attack gunmen

yelled that they had warned people to stay away from the bowls. from from ynonne ndedge in abuja. >> reporter: raphael casts his vote for a president and parliamentians at the provincial station in abuja. things wept smoothly here. this process is happening in 120,000 locations across the country. >> i voted, i believe that it could take us to the level we want to go. under security. education and structure. >> there was some violence in the north. several were killed when boko haram attacked voters going to polling stations. thousands of agents were

deployed to protect voters. in the state where there has been election-related violence voter registration was delayed by hours. hundreds died in 2011. voters were undeterred. >> i shouldn't be afraid because i know my hand is behind the creator. and there's nothing that i should fear for. if i do it someone who is angry with what i did - well it doesn't have anything to do with my life. >> reporter: thousands monitored the vote. pvs, permanent voter cards, were used for the first time. >> they are taking the pvc and making sure that it is in line with the card reader: it is

taking a bit of time. sometimes they try one, two, three, four times until they identify that you are the right person. >> the incumbent president jonathan voted in his state. the main opposition candidate did two. it is expected to be a tight race for the top job. >> voting is being extended into sunday in places where there was technical problems or election materials arrived late. it could mean final results are delayed. for more on the elections i'd like to welcome paul lovic, a professor of african studies at john hopkins. how would ut characterise the elections considering the violence? >> the logistical problem is

understandable because of the scale of the electorate roughly 68 to 50 million. 150,000 polling places and allegedly 300 will be required to be extended. this is the greatest surprise in nigerian political history. mohammed emerged as a candidate when no one gave them a chance. this is a spectacular opposition democracy, and one that shocked everyone and led to the postponement of the election for february to today, because of the polls showing the opposition party, the a.c.c. was competitive with the ruling party. it's a shock and example of the ruling party democracy.

>> do you feel issues have been addressed. >> yes, this is an election where the changes in nigeria is the incumbent always wins. this is the first challenge that i have observed where the challenger could make a set of critiques and the electorate shifted. i was there in january, and the shift was palpable. people in the south, where muhammadu buhari was not popular, were beginning to say we need a change we have lost territory, boko haram in the north, and the corruption is unacceptable. 16 years of one party ruling has caused problems we need to consider it. anyone winning the application

must bin 50%, and 25% in two-thirds of the states. this will be an interesting election, and one that will make a difference in nigeria one way or the other. >> paul professor and associate professor of african studies. great to have you on the program. >> chaos in sierra leone as splits try to enforce a 3-day lock down. police were sent to the border to stop anyone entering their country. the president announced emergency measures enabling authorities to restrict movements. we have the latest now. >> reporter: they came looking for food and when there wasn't enough, fights broke out. this is an impoverished neighbourhood near sierra leone, and a hot bed for ebola cases. hundreds of people defied a

government lock down. >> translation: people are desperate for food because of the distribution. they think they will not get food because of the numbers present. this led to panic. >> reporter: many were custody, the police struggled to deal with the crowd. >> we await the arrival of the military, they have been able to but things under control. >> reporter: health teams were send door to door. in the last knew months a number of new cases have fallen and it remains a threat. 6 million were asked to remain indoors for three days. >> we want to re-energise people remind people. we've been in the fight for 10 months. people are tired, be complacent. >> more than 10,000 have been killed. and 79 new cases were reported

in the three worst-affected countries. many understand the need for a curfew. for those below the poverty line it is not an option. >> because of the 3-day lockdown, there's no way to get food. when they heard of the supply they came around so they could have something for the three days. >> it's not just sierra leone. guinea declared a health emergency. the president ordering restrictions and confinement. many are concerned the government would not be able to supply adequate food and supplies. new vaccines awareness and quarantine are steadily winning against the virus. for the people of the country the fight against ebola is far from over. >> talks in iran's nuclear

programme entered a critical stage. trying to meet a deadline. james bays has more from lausanne. >> these talks are at a crucial phase. last week and for the past three days, the u.s. secretary of state and the iranian prime minister were negotiating. now foreign ministers have arrived or are on their way. first to get here is the french foreign minister. known to be a hawk in these negotiations. >> iran absolutely has a right to nuclear power for civilian purposes. as for a bomb it's a nox the discussions have been long difficult and are pressing ahead. what is important is the content of the agreement. i insist on the transparency of the mechanism and controls so any agreement made is respected. >> reporter: germany's foreign minister has arrived.

u.k. russia and china are expected during the weekend for intense discussions. at a session between the u.s. secretary of state and iranian foreign minister both joked the talks may continue into all hours of the day. >> i'm expecting the evening today. evening, night, midnight. >> morning. >> morning. >> among the iranian delegation there seems to be a growing confidence but the u.s. secretary, ernst mon as was giving nothing away. >> mr secretary, are things going well? are you hopeful to get a deal this £. -- this weekend. >> reporter: the hotel where the talks are taking place, they look over the alps. he told reporters when he looked at the mountains it remaintenance him the hardest part of any climb is the last

bit. >> workers rights. advery kates say employees need unions. not everyone believes they are good for the economy. we look at the labour movement. that's coming up next.

welcome back. for more than a century labour unions played an important role in the workforce, taking credit for higher wages, shorter hours and safer working companies for members. over the last generation the role in american life shrunk dramatically. it makes it harder for businesses to grow hurting the economy in the process. tonight we take a deeper look at the labour movement. with memberships declining, and states in strong holds - the labour movement is trying to change and evolve. nowhere is it more apparent than in the midwest. we have this report from

chicago. >> in chicago manufacturers from around the world checked out new supply chain technologies at a show. >> our system will take the order. >> the event is hold at the largest convention centre for three decades. a few years ago several exhibitors threatened to go elsewhere if chicago didn't negotiate work rule with labour unions. >> what are the exhibitors able to do now that they weren't a few years ago? >> prior to the work rule changes, exhibitors could not put anything up themselves. >> this was a pivotal moment for the union stronghold. a city where a little more than a century ago striking workers battled in the streaks for an 18 hour work day. unions in illinois and the rest

of the nations feel the heat. membership dropped significantly, and 25 states have right to work laws. making it illegal to force private sector workers to pay dues. there's pressure building in illinois. >> we have a new breed of leaders. they see a new america. >> steven ashby teaches employment relations. he thinks corporate america has gotten tougher. when it comes to organised labour, and thinks unions have gotten softer. >> in the '50s, '60s '70s there was social law, a positive relationship between relations and the unions. it's been gone a long time. there's a lot of leaders acting like it still exists. so they are slowly dying. >> unions negotiated company

friendly contract to help them better compete. the last contract signed with the big three car-makers had a no-strike clause and lower wages for new workers. but some see opportunities in an improving company and a growing wage gap. >> i'm a worker. me two have been fighting for $15 and the right to form a union in chicago, fast food workers are rallying for a higher wage. the union is trying to organise workers like nancy, who worked at mcdonald's and makes $8.35 an hour. >> we are not asking for a rich life for all workers. we deserve it. >> low growing industries like fast food retailing and service

are right for organising. they need to do a better job marketing themselves to the workers. >> there's a general attitude if i'm in the union it the be great. if i'm not in the union, they are not doing anything for me. that's a good problem. >> ironically right to work could be a big benefit. he said it could force labour leaders to be more involved with workers, which could build union memberships. >> a key even in the growth was a disaster that took place. labour leaders and workers that gathered in new york city remember those killed in a factory fire and changed the landscape for organised labour. courtney kealy reports. >> reporter: bells toll flowers laid on the sidewalk and the building where garment workers lost their lives.

>> my grandmother and two aunts lay dead in the street right here. >> wednesday people gathered on the corner of the west village to remember the triangle shirt waist factory fire ism it was known as the fire that changed america. >> joel is a retired union attorney, part of a coalition that is working on a memorial to remember the event. >> march 25th. 1911. young women and children toiled away at sewing machines for hours. >> that was where the factory was. the fire started in the scrap bin and within minutes the top three floors were ipp gulfed in flames. doors were locked to prevent workers taking breaks. women and children plunged to their depth. women tried to escape.

only a few got out. don's relatives were in the fire. his great aunt died her sister survived. >> she slid down the elevator cable, landing on people's heads. that was the last elevator to go up. >> many burnt to death. others chose another way to die. >> rather than be ipp sinnerated 60 jumped to their deaths. >> it was over in a few minutes. 146 people mostly young women and children were dead. works place regulations were changed. there's a lot more reform that needs to be enacted. many activists say the same unsafe conditions existed today around the world. in 2012, a massive factory choir killed 117 in bangladesh. a year later, in bangladesh, a

building that housed a garment factory collapsed killing more than 1,000. this month human rights watch released a report exposing inhumane conditions. in the u.s. the triangle factory fire worked and joel said many workers are fighting for basic rights. >> if you look at the commemorative button we are all workers. immigration justice, raising wages, the right to organise. income and equality and safety in the work place. these are things that is hoped that this memorial is thinking about. >> one reason why a century old tragedy is solely remembered. drinking and talking. joining us now is jeffrey, an associate director of the worker

institute at cornell university. and christy, a regional director from the association of american educators, great to have you with us on a deeper look. as we look back to the tragedy, what was the last impact? >> it shocked the confidence of the nation leading to two things. one, fundamental question about unrestrained capitalism and the need for regulation. there were two interventions pursued to deal with the tragedies. one was an active role for the government and the second was workers unions to protect work places. we made a lot of progress. it wasn't until the '70s that provided for occupational safety and health act. today, 4,000 workers die going to work. there's more work to be done to protect workers on the job. >> a lot of work needed to be

done. >> where do we stand in protecting workers' rights. >> if we are talking about unions i say that yes, we can look at unions private and public and say there are things doing to make sure the laws on the books are enforced and workers are protected. it sounds really good. i listen to the two part series and it sounds good and warm and fuzzy. there's an underbody to the union. that is some of the stuff that we are not talking or hearing about. the pendulum swinging too far. i would like to discuss the whole picture. what is the confident we should be having. >> we should be talking about individual freedom and rights. workers want benefits and all

the fluff. they don't want the political power and money spent on politics. i heard the others talk about the capitalism and you look at salaries leaders, and they are far bigger than other contract big shots. people want protections, they want associations and a professional. unions have put so much more into what they are doing. >> people are learning about it. they don't like it. >> does the little guy out here? >> i think the little guy is losing out on society. one of the fundamental concepts we are facing is the wealth distribution. we are getting ready to celebrate the 80th anniversary of the act which was passed in 1935. workers had depressed wages at the time. it was passed as a matter of

federal policy to promote the collective bargaining policy. the act worked. in the 1950s, and 1960s over 30% of the workforce as unionized. during those decades average wages, not just union workers, raised more dramatically than any time history. as unionization has declined we see an increased distribution of wealth and power. and that puts economy and society at risk. >> some called 2015 a tipping point. 20 states increased their wages. wal-mart announced it would increase its wages. would you agree 2015 is a tipping point. >> there's a growing consciousness that this distribution of wealth and wages is a drag on the economy. and workers cannot enjoy the american dream when they are

making low wages. the fact that wall mart said it would raise their wages, is an as a result, an effort on the part of low wage workers, fast food domestic. all organising to raise the wages. it's a tipping point. >> do you agree with that assessment. do americans need labour unions. >> i take issue with the unequal distribution of wealth. our country was built on capitalism. it is ridiculous and i hear living wage the new flavour of the week. what is the living wage. it used to be that a mcdonald's worker was someone in high school, college. i don't know that making a burger was meant to be a career or a job to raise a family of four on. i don't pooh-pooh anyone that does that for a living but it's not sustainable, paying $15 an

hour to do a job held by high school students. it sounds good it's rainbows and unicorns. if you look at the numbers, the economics of it it doesn't make sense. it's not possible. the idea that etch is the same -- everyone is the same paid the same goes through life the same. that's the issue i have. they want everyone the same. doesn't matter if you are exceptional or not. you are the same as everywhere else. i take huge issue with that. >> as an educator you were part of the union, what turns you off from the union model? >> for me obviously being part of a teachers union, private sector is definitely different to the public sector. >> more accountability in the private sector. >> no collectively bargaining against the taxpayer doesn't make sense. no one is sitting at the table. you have you know inmates

running the asylum. there's a finite amount of money going into the public sector for people and employers. and to sit there and suck it dry - we see school districts that lost millions, have been - you know where they have to lay off teachers to keep the benefits and the salaries for teachers. we are seeing larger class sizes. less teachers. they are trying to maintain the union contracts. no one is it issing for the taxpayer. the pendulum has swung too far. >> you are waiting to respond. >> let me say a few things first, i'm the proud son and father of teachers represented by unions. and i'm disturbed by the demonisation of teachers in this country, millions of whom go to work on the front lines, and they are the strongest fiercest activists for quality education

for all students - number one. number two the notion that the people working in fast food restaurants are high school students is not true. a large number of people are depending on us to support families. it's exceedingly difficult. >> no one is saying etch should make the same wage. we have a distribution of wealth that is obscene. more and more people see that. the five walton heirs control about $70 billion in wealth. the same wealth as the bottom 30% of the american people. people recognise that that is tipping too far in the other direction. if you look at post war, post-recession recovering in the 1940s, 1950s, 70, 80, 90% went to the bottom 90%. every post recession recovery the top 10% have a larger share so that in the recovery in 2008

recession. 95% of income games went to the top 10%. the pendulum is swinging in the wrong direction. society is swinging in the wrong direction. and the decline of unions means that working people have stagnant wages, declining wages, less disposable income. they can't spend money on goods and services it's a drag on the economy. it's a problem, a problem that can be solved in a number of ways one of which was to make it easier on unions. >> one in five according to a gallop poll don't trust the unions. why do you think that's the case? >> over 50% of workers would like to join a union if they could do so without the risening of doing their jobs. people recognise unions can help

them get better benefits, enjoy safer conditions. the national labour relations act bestowed the legal right to organise. it doesn't exist. it requires a great act of courage. i think workers who join unions... >> i want to give a chance to respond. >> doesn't it come down to choice? >> i appreciate that. the choice that you need bravery to start a union. i don't know if you belong the union, my counterpart that is talking. so much was said that i take issue with. i have been in a union. it takes bravery to say what are you spending my money on. i'm so fired up. >> let me move the conversation forward. >> i want to say one thing, i really want to touch on this. the idea - we talk about

demonizing people and i'm glad he stands up for teachers. they are good people. what about demonizing someone for what they make. you talk about the waltons. they donate more to public education than anyone else. i guaranteed that their foundation spends millions. when did it become wrong to live the american dream. when did it become a bad thing. i'm blown away by that. who is it that deserves wealth. what is the cap of that. what are people allowed to make. i never said that everyone that works at mcdonald's is a high school student. when i was in high school that is who worked there. i'm 40, i'm not terribly old or young, i'm in the middle. now we are seeing people demanding $15 an hour. i have four kids i'm married, i want a mortgage. it's not sustainable.

it sounds good on paper, it doesn't work like that. >> what is the pathway to a stronger labour movement. >> in my opinion, reform. the idea is reform. for too long unions rely on the fact that they are not compelled but forced to join. when you have people and money, and numbers regardless it doesn't matter. i understand that we have a couple of right to work states and that is growing. in compulsory unionism states everyone has to join. what is the incentive for doing what is right by the members. there isn't any. we see in wisconsin, with a teacher's union, right before the right to work. we are seeing the local unions reform. they understand that they have to offer benefits that makes sense. it's beneficial. any time that an employee can have a voice in the union is a

good thing. right to work and giving a choice will help that. >> can unions mobilize workers in new ways. >> i think they can. there's evidence that there are millions of workers recognising that the only way for the voice to be heard is if they organise through collective organizations. i want to make sense of wal-mart, and the wealth that the walton family is accruing. i don't have anything against people making money. today there are wal-mart workers who collect food stamps. it means they are paying low wages that you and i are subsidizing low wages. i think the fact that wal-mart is saying we'll have to pay wages is recognition that wages are too low. unions need to become creative. recognise that times change and that that is previously what it

is doing. i think the future is very - to me is very hopeful. it will require workers to tip the pendulum in a different direction. most recognise that the increased distribution of wealth is fundamentally undermining the american dream. it's a dream of prossesty and democracy. the concentration of wealth - money increasingly corrupting the process. it's a bit of cynicism. it's something i'd like to say. when we look and see that there's a shift in the political culture. there was a time when we lived in an aspirational culture. workers had decent benefits others looked at that and said that's wonderful. i want that. today increasingly people say

here is a unionized public service. i is have it i don't, they shunt. >> in fairness just quickly. >> first of all, as far as the collective. i know my worth and i will negotiate my own contract. i don't want to be a cog in the system. i take issue with the collective thing, it's about choice. do you want me to join the group, go ahead and compel me. if unions were great, and was so needed everyone that is given a choice. that's the bottom line. >> we'll have to love it there. we appreciate your time. thank you both. great to have you with us on eboni deon. >> coming up op al jazeera. the high tech way police departments enter new york, and

they are making a surprise discovery. >> good news. dr orton discovered a break through, and is giving away 1 million bottles free. >> i spent 30 years looking for an instant breakthrough to reduce the appearance of wrinkles that can be applied topically, instead are with surgery or invasive techniques. i found it.

a

dozens of protesters clashed with troops. some of the crowd threw stones at israeli soldiers. israeli military responded with rubber bullets, grenades and tear gas. a demonstrator was wounded and another arrested. we spoke with a senior fellow at the american university in beirut. >> the only way that a dispute of this conflict will be resolved i believe, is one of three options. either there has to be a change of leadership. the other way this could happen is a massive grassroots movements on palestine and israel to push forward a negotiating mechanism that the leaderships could agree on.

the third way is massive external pressure on both sides by international powers the u.s., the europeans, russians and the others using flora like the united nations. those are the three mechanisms that seem likely it's hard to tell which may happen to become operative. >> we invite you to join us tomorrow night as we take an indepth look at the fragile relationship getting new information on the germanwings plane crash in the french alps. german authorities say there's no indication na german pilot andreas lubitz was motivated by terrorism. >> today near the crash site the families of the victims held a memorial. the service was attended by residents. many say they were deeply affected by the crash and came

out for support. >> investigators believe andreas lubitz, the plane's co-pilot was kuvering from clinical -- suffering from clinical depression. the "new york times" is reporting that andreas lubitz was receiving treatment for vision problems that may have affected his ability to fly. one of the parents of a victim called for a look at how pilots are treated. >> at the altar, there were 150 candidates. relatives and locals coming together to remember them. >> it's terrible. horrible for the families. there's no words for this. i'm broken. >> on the mountainside the task of recovering remains and wreckage continues. it will take another two weeks. the second black box is missing. the need for data is less urgent now the cause is clear. trying to understand what drove

the co-pilot to such a heinous act is the focus of the investigation. one newspaper quotes a girlfriend saying andreas lubitz worried that his career was threatened and he talked of doing something dramatics. german doctors say he was undergoing treatment for an unspecified condition and was flying despite being told not to. that raised questions about his airline's assessment of his suitability to fly. at the dusseldorf airport, the destination of the flight. the passengers signalled a determination to carry on flying. >> i don't have concerns i trust the airlines i have flown countless times, it was sad and i shed tears when i heard about it. now we have to move on if it's okay to say that.

>> friday europe's aviation agency recommended airlines adopt a policy of two crew members in the cockpit of all times. relatives were promised compensation of over $50,000. given what is known about the cause for the tragedy, the final bill will be higher. >> a commuter train crash in southern california injured 19 people. witnesses say the train struck a car near the campus. it appears the driver was trying to turn and didn't see the train. the train's conductor and the driver were hurt. two of the train's three cars derailed but remained upright. brooklyn new york is rolling out gun fire protection called shot spotter, to improve police efficiency. jacob ward science and

technology correspondent reports that it revealed shocking information about the volume of gunfire in america. >> in many ways oakland california is the perfect place to live. it's warm and beautiful. an hour from the pacific, 3.5 from yosemite. this city is plagued by gunfire. it's not only dangerous, it's incredibly loud. the distinctive noise led to a system to destect kun fire the moment it was pulled. shot spotter is one of several companies that sell this system. the technology is born and adapted by the u.s. military to stop snipers. the microphones record conversations, but designed to

protect gunshots and can triangulate the shooter's location and trigger police. a pilot programme in new york detected gun fire in the december shootings of two police officers. the system may reveal how inaccurate the understanding of gun fire is in the country. usually it is tied to 911, but gunfire may go unreported when it doesn't hit anyone. >> when someone fires a gun people call 911, 20% of the time. the first challenge is four out of five times no one knows it happened apart from the person that pulled the trigger. >> there has been 414,000 incidents of non-fire related crime, it is based on 911 calls. shot spotter suggests they may

be 80 times more efficient. if the american population knew how well shotters fly through the air and little kids follow gunfire, i think the reaction about the gun debate would be different. >> with 300 sensors in place, the system may be the beginning. researchers say it can have a lifelong impact on a child's health. children are especially sensitive. their brains and bodies are developing. high doses of adversity not only affect brain structure and function they affect the developing immune system and the way our dna is read and

transcribed. whether or not acoustics help the police in the city. crimes may be revealing. once and for all how many guns are fired and how that is affecting everyone coming up why the empire state building and landmarks around the world went dark toon. -- dark tonight.

>> tomorrow. you know his music but what about the man? >> i was given a gift. >> up close and personal. behind the scenes of the biggest hits... >> she was a troubled girl. >> brightest stars... >> kids don't want to "own", they just want to "play". >> and the future of music. >> the record business is in trouble. >> every sunday night, >> i lived that character. >> go one on one with america's movers and shakers. >> we will be able to see change. >> gripping. inspiring. entertaining. talk to al jazeera. tomorrow, 6:30 eastern. only on al jazeera america. the world wildlife made its way around the world, drawing attention to environmental issues. the empire state building dimmed its top light. in paris the eiffel tower went dark changing the look of the skyline. paris will host a climate conference at the end of the year. lights in tokyo were switched

off. allowing some residents to enjoy candlelight. it's the eighth i don't remember cities have participated in the campaign. talk about a roller-coaster of temperatures with rain and spots. let's go to kevin corriveau. >> as we go through the weekend we'll see temperatures in the if north and east of the first of all, it is the snow that we are talking about across much of the southern part of new england, we'd have over three inches of snow and we'll see snow as the system pulls off the coast. towards boston we are looking at two to the south. boston - seeing 30 degrees to new york. temperature wise we will not see a major increase.
