VIDEO: Survey reveals massive meltback in NZ glaciers

Researchers are painstakingly piecing together thousands of photographs of New Zealand's Southern Alps to tell a story about our shrinking glaciers.

The annual glacier snowline survey, a collaboration between NIWA and Victoria University, took place in March, and showed the summer's marine heatwave has resulted in one of the largest glacier melt seasons observed since flights began in 1977.

Since the first survey 40 years ago scientists have detected a 30 per cent loss of ice.

During the survey, conducted from a fixed wing aircraft, the scientists on board take photographs to determine how much snow remains after summer.
They will compare the photos to ones taken in previous years and make digital models of the glaciers to measure the changes.

Survey founder Dr Trevor Chinn says there was so much melt over summer than more than half the glaciers lost all the snow they gained over last winter, and some from the winter before.

“A glacier is the best climate change indicator you can use,” he said.

NIWA climate scientist Dr Andrew Lorrey says the South Island glaciers hold a lot of water that is crucial for ecology, agriculture and power generation so it was important to monitor them.
“You can say what you like about temperatures on the ground but you can’t make a glacier lie.”

The annual survey forms part of the Climate Present and Past project, which looks at recent and historical climate data to track past variability and changes in climate.

Joseph Cederwall: The End Of ‘Objectivity’ In Journalism

... and the dawn of something much better?
2019 looks like it might well be another really bad, terrible, not so good year for the traditional journalism model globally. Already in January three leading US digital outlets—BuzzFeed, the Huffington Post, and Vice announced layoffs that have left many accomplished journalists unemployed. Consolidation of journalism looks set to continue unabated as larger (sharky) media conglomerates swallow up smaller players globally. We also appear to be witnessing the death throes of the concept of ‘objective’ truth in journalism. However, perhaps that is not at all as bad as it sounds, and we are just finally waking up to the reality that it never really existed in the first place... More>>

 
 

Environment: Government To End Tenure Review

“Tenure review has resulted in parcels of land being added to the conservation estate, but it has also resulted in more intensive farming and subdivision on the 353,000 ha of land which has been freeholded. This contributed to major landscape change and loss of habitat for native plants and animals,” said Eugenie Sage. More>>

Health: Prohibiting Smoking In Vehicles Carrying Children

Under the change, Police will be able to require people to stop smoking in their cars if children (under 18) are present.
