World Food Day: coping with the climate's impact on food security – in pictures

The Guardian - Sun, 2016-10-16 18:00

Every day, one in nine people around the world do not have enough food to support a healthy, active lifestyle. The problem has been compounded by climate change, which often has a devastating impact on food security. Severe drought across three continents has led to shortages of food, water and energy in recent months. Tearfund is helping communities to grow crops, find alternative sources of food or fuel, and increase resilience to climate change

Hunted to the brink, but Africa’s reviled vultures are vital in fight against disease

The Guardian - Sun, 2016-10-16 09:05
Wildlife photojournalist of the year exposes the plight of the endangered scavenger

Vultures are rarely viewed as the poster boys and girls of the natural world. They have repulsive eating habits and are strikingly ugly. Nevertheless, they play a critical role in maintaining the ecological health of many parts of the world.

Vultures consume animal carcasses more effectively than any other scavengers and because their digestive juices contain acids that neutralise pathogens such as cholera and rabies they prevent diseases spreading. They act as dead-end hosts for numerous unpleasant ailments. But many ecologists are now warning that vultures across the planet are under serious threat thanks to habitat loss, deliberate and accidental poisoning, and use of the birds’ body parts as traditional medicine cures.

Shark conservationists fear backlash after viral cage-smashing video

The Guardian - Sun, 2016-10-16 06:02

Experts emphasize that the incident, in which a great white broke through a cage holding a diver, was a ‘one in a million occurrence’

Shark enthusiasts are concerned about the impact of a viral video that showed a great white shark breaking into a cage occupied by a diver in Mexico.

The diver survived, but the harrowing video shed light on a decades-old tourism industry that allows people to be within an arm’s length of great white sharks, separated only by the sea and some metal bars.

Kigali deal on HFCs is big step in fighting climate change

The Guardian - Sun, 2016-10-16 05:53
The deal done in Rwanda on Saturday will cut greenhouse gases. We assess its global significance

They went to Kigali to eliminate hydrofluorocarbons (HFCs) and take 0.5C out of future global warming, and the 170 countries that successfully negotiated an amendment to the Montreal protocol treaty agreed to get rid of 90% of them. Not bad for four days and three long nights of hard work.

The Kigali deal on HFCs is in fact fiendishly complicated and has taken years to negotiate in various technical and political forums. The final agreement, announced on Saturday morning caps and reduces the use of HFCs in a gradual process beginning in 2019.

Greenhouse gases deal will make little difference to west

The Guardian - Sun, 2016-10-16 01:14

HFCs deal is vital for reducing emissions but poorer countries rely on old coolant technologies and will now have to upgrade

They went to Kigali to eliminate hydrofluorocarbons (HFCs) and take 0.5C out of future global warming, and the 170 countries who successfully negotiated an amendment to the Montreal Protocol agreed to get rid of 90% of them. Job done. Not bad for four days and three long nights’ work.

In fact the Kigali deal on HFCs, announced on Saturday morning, is fiendishly complicated and has taken years to negotiate in different technical and political forums. It was only struck by an ambitious agreement to give countries different timescales to phase them out, alongside major chemical and big food companies accepting change, the personal determination of the US secretary of state, John Kerry, to get a deal before the election and developing countries agreeing to invest heavily in new technologies.

Climate change: global deal reached to limit use of hydrofluorocarbons

The Guardian - Sat, 2016-10-15 16:11

Global deal on HFCs – greenhouse gases far more powerful than carbon dioxide – seen as ‘largest temperature reduction ever achieved by single agreement’

A worldwide deal has been reached to limit the use of greenhouse gases far more powerful than carbon dioxide in a major effort to fight climate change.

The talks on hydrofluorocarbons, or HFCs, have been called the first test of global will since the historic Paris Agreement to cut carbon emissions was reached last year. HFCs are described as the world’s fastest-growing climate pollutant and are used in air conditioners and refrigerators.

British households fail to recycle a 'staggering' 16m plastic bottles a day

Energy storage vital to keep UK lights on, say MPs

The Guardian - Sat, 2016-10-15 15:01

Committee urges investment in batteries and smart demand technologies to ensure energy supply as old coal and nuclear power stations close

Large-scale batteries to store energy and devices that switch themselves off are likely to be key technologies for keeping the UK’s lights on while shutting down old coal and nuclear plants, an influential committee of MPs has said.

The threat of blackouts has receded for this winter after scares earlier in the year, National Grid said on Friday, citing a reprieve for Yorkshire’s Eggborough coal-fired power station, as well as greater flexibility from companies with big energy requirements.

No shortage of birds as the chilly months approach

The Guardian - Sat, 2016-10-15 14:30

Rogerstown, County Dublin Brent geese are here, and black-tailed godwit have begun arriving from their breeding grounds in Iceland

On a bright morning we are sitting with volunteer warden Aileen in a bird hide a little north of Dublin. We have come to watch the first of the avian migrants for whom the south bank of the Rogerstown estuary is a favoured wintering spot. It clearly isn’t the best time to be here, as feathered visitors are so far in short supply. Perhaps the house martins swooping across the water to vanish southwards are a sign that the chilly months ahead are not yet to be taken seriously.

Yet there’s no shortage of birds. Opposite us, five cormorants sit passively side by side on a series of water-logged posts. Bar-tailed godwits line the margins of the saltmarsh, occasionally preening but mostly motionless. Redshank, curlew and dunlin vigorously probe the shallow margins, and widgeon and teal up-tail as they feed in the slightly deeper water.

Energy subsidies should focus on storage and cutting demand, MPs say
