Climate impacts 'overwhelming' - UN
The impacts of global warming are likely to be "severe, pervasive and irreversible", a major report by the UN has warned.
Scientists and officials meeting in Japan say the document is the most comprehensive assessment to date of the impacts of climate change on the world.
Some impacts of climate change include a higher risk of flooding and changes to crop yields and water availability.
Humans may be able to adapt to some of these changes, but only within limits.
An example of an adaptation strategy would be the construction of sea walls and levees to protect against flooding. Another might be introducing more efficient irrigation for farmers in areas where water is scarce.
Ukraine's Gas Princess and Chocolate King fight for presidency
Analysis: Yulia Tymoshenko and Petro Poroshenko both tainted by past decade of political failure
Daniel McLaughlin
Dr Iron Fist may have thrown in the towel, but the Chocolate King and the Gas Princess should make Ukraine’s presidential election a fascinating fight.
Vitali Klitschko, a former world boxing champion with a doctorate in sports science and political party called Udar (Punch), dropped out this weekend and put his considerable weight behind Petro Poroshenko, a billionaire who owns Ukraine’s biggest confectionery maker.
The Chocolate King has a handsome lead in opinion polls ahead of a May 25th vote to find a successor to Viktor Yanukovich, the disgraced former president who fledUkraine in late February.
But Poroshenko, a former foreign minister who speaks at least three languages fluently, finds his path to the presidency blocked by a tenacious political survivor and fierce campaigner – Yulia Tymoshenko, whose 1990s exploits in the energy trade saw her dubbed the Gas Princess.
'Slavery exists in every country'
The Global Freedom Network, a new working group of religious leaders, aims to put a stop to slavery. Gina Dafalia is hopeful that the brainchild of an Australian billionaire and her Walk Free Foundation will succeed.
DW: What inspired Australian billionaire Andrew Forrest to take up the fight against slavery in the first place?
Gina Dafalia: He was visiting his daughter who was travelling at the time and working in an orphanage. When Andrew and Nicola went along to visit they discovered to their horror that the children in the orphanage were sold into sexual exploitation.
When Andrew returned to Australia, he decided that he needed to have a look at the business operations of his company, which is one of the largest iron ore companies in the world, Fortescue Metals Group. He discovered he also had slavery in his own supply chains.
He then put policies and procedures in place to tackle it. He also went a step further: He used his influence and his leverage to stop suppliers that were using slave labor. But that wasn't enough. He wanted to create a global movement where slavery would be abolished.Brazilian police, troops, occupy slum by Rio airport
March 31, 2014 - 6:18AM
Rio de Janeiro: Brazilian police backed by troops have occupied a massive slum next to Rio de Janeiro's international airport without firing a shot to secure one of the city's most violent neighbourhoods long run by drug dealers.
Wresting control of the area from drug lords was a security priority for authorities because it surrounds the expressway to Galeao airport where tens of thousands of people will arrive in June for the soccer World Cup.
Marines in armoured cars reinforced the operation on Sunday that took barely 20 minutes to re-establish police control over the Mare slum complex, where 130,000 people live in poverty on the north side of Rio.

Nigeria 'attempted jailbreak' leaves more than 20 dead
Twenty-one people have been killed in an attempt to escape from detention at the headquarters of Nigeria's secret police in the capital, officials say.
Police said the trouble started when a prisoner beat a guard with his handcuffs in an attempt to escape.
Local media say many of the police detainees are suspected members of the Islamist group Boko Haram.
The group has waged a violent four-year campaign to install a radical form of Islam in the north.
Thousands have been killed since the conflict started in 2009.
At least three million people have been affected, Nigeria's Red Cross said last week.
Gingerly, Iran begins to rock out
In 2008, Iran banned all pop music. But a recent female solo performance signals growing freedom in a country where heavy metal musicians have been told to stay seated on stage.
By the bleak standard set by 35 years of Islamic revolution, Iranian musicians have never had it so good.
Lady Gaga is not about to play Tehran. But Iranian musicians say the growing openness of the past two years has now blossomed under centrist President Hassan Rouhani, enabling live performances today that would have been impossible not long ago.
Exhibit A is a groundbreaking show that just finished a 20-gig run in Tehran’s renowned Vahdat Hall. Redefining what is acceptable on stage, women sang solos; Western songs filled the playlist, from John Lennon to Frank Sinatra; and most lyrics were in English.
Audiences who crammed into the plush multi-story theater gasped at the spectacle, some singing quietly along as the lead female vocalist – wearing a maroon head scarf that fell to her waist – belted out Amy Winehouse’s “Back to Black.”
