Barack Obama and Justin Trudeau to join forces on climate change
US and Canadian leaders expected to announce a series of common measures including methane emissions cuts and protections for rapidly warming Arctic
Barack Obama and Justin Trudeau will commit to work together to fight climate change and protect an Arctic experiencing the mildest winter ever recorded, sources familiar with the initiatives said.
The two leaders were expected to announce a number of common climate measures at a meeting at the White House this week, from a 45% cut in methane emissions from the oil and gas industry to protections for a rapidly warming Arctic.

Work will begin this year to shut down Fessenheim, which is at the centre of a row with Germany and Switzerland
The French environment minister, Ségolène Royal, said on Monday that work will begin this year to shut down the country’s oldest nuclear power plant, at the centre of a row with neighbouring Germany and Switzerland.
In doing so she implicitly contradicted a Green party minister who had said on Sunday that the process to close the Fessenheim plant in Alsace would be completed, rather than merely started, by the end of the year.
The two ministers spoke to the French media after a row sparked on Friday when Germany demanded that France close down Fessenheim following reports that a 2014 incident was worse than earlier portrayed.
Royal said on the TF1 television channel that shutting down a nuclear reactor “is not just turning off a tap” and involved not only time-consuming official paperwork but careful decommissioning under strict safety conditions, along with collateral issues such as the question of job losses.
“A nuclear plant like Fessenheim employs 2,000 people,” she explained, saying the site could eventually be converted for renewable energy, or maybe a car factory.
On Sunday France’s housing minister, Green party member Emmanuelle Cosse, had said that closing Fessenheim this year was “the timeline ... the president [François Hollande] has repeated to me several times”.
“The process of stopping a reactor is simple enough,” she added.
France’s Nuclear Safety Agency has said that safety at the plant was “overall satisfactory” but that the government’s energy policy “could lead to different choices” regarding the facility, which is near the German and Swiss borders.
It said there was “no need” to shut the plant from a nuclear safety point of view.
France has promised to cut reliance on nuclear energy from more than 75% to 50% by shutting 24 reactors by 2025, while stepping up reliance on renewable energy.
Fessenheim, located on a seismic fault line, has worried French, German and Swiss environmentalists for years.
In September, Hollande said the plant, in operation since 1977, would not be shut this year, contrary to a 2012 campaign promise, because of delays in completion of a new plant in northern Flamanville.
On Sunday, Cosse said that to reach its target, the government would have “to close other nuclear plants, other reactors, obviously, over several years.”
Obama administration pays out $500m to climate change project
The first chunk of a $3bn commitment made at the Paris climate talks ‘shows the US stands squarely behind climate commitments’, the State Department said
The Obama administration has made a first installment on its $3bn pledge to help poor countries fight climate change – defying Republican opposition to the president’s environmental plan.
The $500m payment to the Green Climate Fund was seen as critical to shoring up international confidence in Barack Obama’s ability to deliver on the pledges made at the United Nations’ climate change conference in Paris in late 2015.

Roman fort, wolves and bears lost to time
High in the Cambrian mountains of mid Wales, perched on a slope above the chaotically youthful river Afon Tarenig, the bleak aspect of the Roman fort at Cae Gaer speaks of military expediency and urgent purpose.
In the sunshine of early spring it looks almost serene. But to a newly arrived legionary, in the depths of winter, immersed in an alien landscape still home to wolves and bears, it must have felt like the edge of the world.

- Coal currently provides a third of the state’s electricity supply
- State also aims to double amount of renewable energy produced by 2050
Oregon has become the first US state to pass laws to rid itself of coal, committing to eliminate the use of coal-fired power by 2035 and to double the amount of renewable energy in the state by 2040.
Legislation passed by the state’s assembly, which will need to be signed into law by Governor Kate Brown, will transition Oregon away from coal, which currently provides around a third of the state’s electricity supply.

On Luzon Island, scientists have accidentally discovered the smallest of the giant Rafflesia flowers, a species that may be critically endangered, reports Mongabay
In the rainforests of southeastern Asia, a parasitic plant called Rafflesia produces the world’s largest flowers. Some Rafflesia flowers, for instance, can be a meter and a half in diameter, and can weigh up to 22 pounds (or 10 kilograms). These flowers, called “corpse flower” locally, often smell like rotting flesh.
Now, on Luzon Island in the Phillipines, a team of scientists have discovered the smallest of these giant flowers.

Partnering with indigenous groups, conservationists discover a wealth of wildlife in Bangladesh’s most remote region. Including maybe, just maybe, tigers
The locals said there were tigers in the forest. They also said there were sun bear, gaur, dhole and clouded leopard. Few took note, but it turned out, not surprisingly, that locals were right. Conservationists surveying the super-remote, little-known Chittagong Hills Tract region of Bangladesh have taken the country’s first ever photos of sun bear and gaur. And last month they discovered a 13-centimetre pugmark (or pawprint) of a feline, which experts believe is a tiger.
“Despite the tremendous challenges [facing] the natural heritage of Bangladesh – all hope is not lost yet,” said Shahriar Caesar Rahman, the co-founder of the new group, Creative Conservation Alliance (CCA). Rahman and his group, which organized the wildlife survey that employed camera traps, have been working in the Chittagong Hills Tract region for five years by partnering with the local tribes and securing support from Bangladesh’s forest department.
