The Nimmie-Caira project could mean the restoration of one of the largest wetlands in the Murray-Darling basin
• Murray-Darling: when the river runs dry

The New South Wales government is close to deciding who will run one of most ambitious environmental projects that have come out of the Murray-Darling basin plan.

If successful, the rehabilitation of the Nimmie-Caira property could result in the restoration of the largest wetlands on the Murrumbidgee river. It will create a sanctuary for water birds, extend vital wetland habitats and preserve a unique area rich in Aboriginal cultural heritage – all under private sector ownership.

An Atlantic Ocean circulation system that warms Europe's climate is weaker today than it has been in 1,000 years, say scientists.

Warm current that has historically caused dramatic changes in climate is experiencing an unprecedented slowdown and may be less stable than thought - with potentially severe consequences

The warm Atlantic current linked to severe and abrupt changes in the climate in the past is now at its weakest in at least 1,600 years, new research shows. The findings, based on multiple lines of scientific evidence, throw into question previous predictions that a catastrophic collapse of the Gulf Stream would take centuries to occur.

Such a collapse would see western Europe suffer far more extreme winters, sea levels rise fast on the eastern seaboard of the US and would disrupt vital tropical rains. The new research shows the current is now 15% weaker than around 400AD, an exceptionally large deviation, and that human-caused global warming is responsible for at least a significant part of the weakening.

My campaigning colleague Jerry Pearlman, who has died aged 84, left his legal mark on landscapes and paths from Yorkshire to Devon through his role as honorary solicitor for the Ramblers’ Association (now the Ramblers) for more than 30 years.

A leader in the campaign for the right to roam, Jerry drafted the bill that formed the basis for the Countryside and Rights of Way Act 2000. In the appeal court in 2002 he helped me in the campaign to reopen the heavily blocked path across land belonging to the businessman Nicholas van Hoogstraten in East Sussex.

First batches appear on shelves before the start of the traditional season and despite cold snap

UK supermarkets have begun stocking the first batches of British-grown asparagus this year, despite the impact of the recent “beast from the east” cold weather system.

Marks & Spencer was first off the block with British asparagus on sale in selected branches last week – nearly three weeks before the traditional start of the eight-week season on 23 April – while Waitrose put the first spears on sale on Wednesday. Sainsbury’s is likely to stock small quantities from the weekend.

A new early warning satellite system reveals countries where shrinking reservoirs could lead to the taps completely drying up

Shrinking reservoirs in Morocco, India, Iraq and Spain could spark the next “day zero” water crisis, according to the developers of a satellite early warning system for the world’s 500,000 dams.

Cape Town recently grabbed global headlines by launching a countdown to the day when taps would be cut off to millions of residents as a result of a three-year drought. Drastic conservation measures have forestalled that moment in South Africa, but dozens of other countries face similar risks from rising demand, mismanagement and climate change, say the World Resources Institute (WRI).
