Polar bears at risk from pollution as well as warmth

Tim Radford

24th April 2015

As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival. more...

In praise of tigers, conservation heroes of the Sundarbans

Joydip Kundu

29th April 2015

The presence of the tigers is the world's greatest mangrove forest vital to its survival, writes Joydip Kundu. It's the fear of the tiger that deters people from entering the forest to cut its trees and hunt its wildlife - and so these majestic predators protect its fisheries, and guard millions of people in south Bengal from the rising seas. more...

Strong marine protection works for fisheries and wildlife!

Bryce Stewart & Leigh Howarth

20th April 2015

The strongly protected marine reserve in Lamlash Bay, Arran, has been a huge success, write Bryce Stewart & Leigh Howarth, with abandant life returning to the once denuded waters. The government's refusal to expand such protections represents a huge wasted opportunity for both fishing and the marine environment. more...

Japan's 'scientific whaling' fail: experts reject plan to kill 4,000 Minke whales

Tony Press

15th April 2015

Japan's latest plans for 'scientific whaling' in the Southern Ocean have fallen at the first hurdle, writes Tony Press. The IWC's expert panel says Japan's proposal contains 'insufficient information' on which to judge its validity, in particular the need for the 'lethal sampling' of over 3,996 Minke whales that is central to the research plan. more...

To protect our seas, first we must reclaim them from 'Big Fishing'

Horatio Morpurgo

10th April 2015

There's strong public support for protecting marine wildlife, writes Horatio Morpurgo - so why aren't politicians championing the cause? Labour and Tories alike fear to challenge the big fishing companies that have come to believe they own Britain's offshore waters and seabed. Now it's up to use to prove they're wrong. more...

Ocean energy plus cybernetics can supply a quarter of the US's power

Shalinee Kishore

14th April 2015

Wave power has a huge part to play in supplying the US with clean, renewable electricity, writes Shalinee Kishore. But to achieve its full potential, we must harness not just the energy of waves, but their predictability - and so so ensure the smooth integration of wave power into the electricity grid. more...

Shark-counting divers off Costa Rica show marine reserves need active protection

Julia Baum & Easton R. White

24th April 2014

A Pacific island paradise 340 miles from Costa Rica's coast should be the ideal place for marine conservation, write Julia Baum & Easton R. White. But while its waters are indeed teeming with life, steep population declines in key shark and ray species show that stronger protection is badly needed. more...

Ocean 'dead zones' are spreading - and that spells disaster for fish

Lee Bryant

9th April 2015

Oxygen levels in our oceans are falling, writes Lee Bryant, producing growing 'dead zones' where only the hardiest organisms can survive. The causes are simple: pollution with nutrient-rich wastes, and global warming. But the only solution is to stop it happening - or wait for 1,000 years. more...

Greenpeace occupies Shell rig after Arctic drilling go-ahead

Christine Ottery & Oliver Tickell

7th April 2015

Days after Shell received US Government backing for its plans to drill in the Chukchi Sea in the Alaskan Arctic, volunteers from Greenpeace have occupied its 'Polar Pioneer' oil rig in the Pacific Ocean to demand a halt to all Arctic oil exploration. more...

Saving Lamlash Bay - and over-exploited seas everywhere

Howard Wood

20th April 2015

A coveted award has put the campaign to protect and recover marine life in the Firth of Clyde, Scotland, into the international limelight. Goldman Prize winner Howard Wood explains how Arran Islanders' efforts to keep scallop dredgers out of Lamlash Bay has brought life, and fish, back to the sea. more...
After more than century of colliery dumping, there's still plenty of coal to be picked up at Seaham Harbour. But now a far more toxic form of pollution is on its way, thanks to UGC - underground coal gasification. Photo: David Robson via Flickr (CC BY-NC-

'Underground coal gasification' hell-fires threaten Tyneside and the North Sea

Paul Mobbs

3rd April 2015

After over a century of coal ash and colliery waste dumping, the Tyne and Wear coastline is no stranger to industrial pollution. But soon a horrific new technology - underground coal gasification (UCG) - will endanger human health and the environment, backed by unflinching Government support and generous lashings of taxpayers' money. more...

Man on an Antarctic mission - taking a plunge for the Ross Sea

Yannic Rack

1st April 2015

How to campaign for the world's biggest marine protected area in Antarctica's freezing seas? If you're Lewis Pugh, the answer's a simple one: swim there! And before your hands have even recovered from the frostbite, fly off to Moscow to persuade the Kremlin to back the idea. Yannic Rack met the intrepid swimmer in a cosy London pub ... more...

Clear blue water! Pitcairn Islands reserve is Britain's biggest conservation initiative ever

Nick Hurd and Zac Goldsmith

20th March 2015

The the creation of almost a million sq.km of the South Pacific as a fully protected marine area builds on a long Conservative tradition of protecting the natural environment, write Nick Hurd & Zac Goldsmith - and as factory trawlers close in on Pitcairn's pristine waters, the initiative could not have been more timely. more...

World's greatest marine reserve around Pitcairn Islands

The Ecologist

19th March 2014

The UK is to create a fully protected marine in the South Pacific more than three times bigger than the UK itself, covering some 830,000 square kilometres. The move may herald further huge designations in the UK's 'overseas territories' which encompass over 6 million square kilometres of ocean. more...

Antarctic warmth brings more snow, reducing sea level rise

Alex Kirby & Oliver Tickell

18th March 2015

Rising temperatures will result in more snow falling in Antarctica, and the build-up of ice will reduce sea level rise from other sources. But as the extra weight of ice makes Antarctica's glaciers flow faster, the continent will still be a net contributor to sea level rise. more...

In March 2012 the Union of Agricultural Work Committees (UAWC) rallied on the Mediterranean Sea between the Gaza seaport and Beit Lahia to protest Israeli naval attacks on Palestinian fishermen and demand the return of fishing boats seized by Israel. Sinc

Israel escalates deadly attacks on Gaza's fishers

Charlie Hoyle

12th March 2015

Under the ceasefire between Israel and Hamas last August, Gaza's fishers were meant to be able to work up to six miles from the coast, writes Charlie Hoyle. In fact, Israel is routinely attacking boats within the zone, arresting fishermen, and seizing boats and nets, never to be returned. Only last week, one fisherman was shot dead after allegedly straying over an invisible boundary. more...

Why a submerged island is the perfect spot for the world's biggest wind farm

Xavier Lemaire

27th March 2015

Way out in the turbulent North Sea, the Dogger Bank may seem like an unlikely place to site a large part of Britain's energy infrastructure. But given the stable sea floor, consistent winds, and distance from sensitive neighbours, it could be the perfect place. Even the fish could come to like it! more...

Coming soon: the 'Big Heat'

Nafeez Ahmed

3rd March 2015

Global warming has been on vacation for a few years, writes Nafeez Ahmed. But that's only because the excess heat - two Hiroshima bombs-worth every second - has been buried in the deep ocean. But within a few years that's set to change, producing a huge decade-long warming surge, focused on the Arctic, that could overwhelm us all. more...

Keystone plankton 'go slow' as ocean acidity rises

Tim Radford

1st March 2015

Increasing acidity in the Southern Ocean is slowing the growth of diatoms, reports Tim Radford. Why worry? Because these tiny plankton sustain essential marine ecosystems, and are highly effective at drawing CO2 down into the deep ocean. more...

End high seas fishing for fairness and sustainability

Reg Watson

9th March 2015

What's the solution to the over-exploitation of fish on the high seas, outside territorial boundaries? Ban it altogether, argues Reg Watson. It would make little difference to the total fish catch, poor coastal countries would reap huge benefits, and the fishing fleet's fuel burn would be slashed. The main losers? Rapacious industrial factory-fishers. more...
