Of science and the Southern Alps
The Southern Alps are acting as a massive carbon sink with weathering of the mountain chain turning rock into soil and absorbing carbon from the atmosphere in the process.
A paper published in Science this week and featuring the research of Lincoln University's Isaac Larsen and Andre Eger, found that rock in the Southern Alps is being transformed into soil twice as fast as previously though.
That's due to the fast rate of mountain uplift in the alps - over one centimetre per year, and vegetation on the slopes contributing to weathering of the rock.
As the Press science reporter Sarah-Jane O'Conner reported:
"By measuring the amount of Beryllium-10, an isotope that only forms at the Earth's surface, Larsen and his colleagues showed soil was being produced on the ridge tops at rates between 0.1 millimetres and 0.25mm a year.
"The peak rate was more than twice what had been previously suggested as the "speed limit" for soil production."
Meanwhile, a team of scientists from the University of Otago have published research that revises the height of Aoraki/Mt. Cook.
The country's tallest peak has dropped in height by 30 metres to 3724m following a major rock ice collapse at the summit in 1991.
Morgan on water quality and climate
Economist and philanthropist Gareth Morgan has delved into the issue of water quality and dairying in a two-part New Zealand Herald series co-authored with Morgan Foundation writer and researcher Geoff Simmons.
It also follows publication of a report by the Parliamentary Commissioner for the Environment, Dr Jan Wright, that details how a shift from sheep and beef farming to dairying has lead to increased leaching of nitrogen and phosphorus into waterways which in turn causes excessive growth of weeds and algae, choking waterways. The SMC rounded up reaction to that report here.
"Let's be clear up front; we aren't blaming the farmers," the Morgan and Simmons write in the first installment of the Herald series, going on to say that like bankers during the global financial crisis, farmers "are just responding to the incentives the market presents them".
The pair outline the physical nature of the problem faced with dairy intensification:
"It all starts with cow pee. Sure fertiliser can be a problem if applied excessively or at the wrong times, but in the main it's not the culprit. Rather it is cow pee - a simple urine splash from a cow is a massive concentration of nitrogen, equivalent to 1000kg of nitrogen per hectare. This is too much for pasture plants to take up by far. Given dairy cows pee a lot and over time the nitrogen seeps down through the soil to find its way into rivers and groundwater, the consequence from higher stocking rates are obvious."
In the second part, Morgan and Simmons propose a solution - a nutrient budget for farmers, who they believe, should also pay for the water they use to irrigate their land. They conclude:
"What the Commissioner for the
Environment's report says is that the mitigation efforts
farmers are making will not stop the rot, more and more cows
is an environmental disaster. What we would say is the
market structures around dairying are what's driving that
quest for more cows - a level playing field would sort that
and while on-farm investment would become less attractive,
downstream investment would take up any slack."
Balance in climate coverage
Meanwhile, Morgan has penned a column slamming former MP and Herald on Sunday columnist Rodney Hide for his scientifically flawed take on climate change.
A January 5 column by Hide suggested historians look back on the Australasian Antarctic Expedition vessel becoming stuck in Antarctic sea ice over Christmas, as "the trigger that finally ended the public fear of global warming".
Wrote Hide: "The expedition's story now is that global warming melted a big iceberg creating the ice that trapped them. That's the climate alarmists' nuttiness in a nutshell: nothing proves them wrong; everything proves them right".
But Morgan, who delved into climate science in researching his book Poles Apart, was unimpressed:
"Temperature hasn't risen since 1997 - climate is a long-term phenomenon. Carefully selected start and finish years can always show something different, but the long-term trend is of rising temperature. As mentioned, no trained scientists are questioning this, just Hide and the losers that took NIWA to court to question their results - and lost".
Morgan goes on to argue argue that media coverage of climate change should represent the balance of evidence on the issue, rather than giving scientists and sceptics equal space:
"More of our media
should follow the lead of the BBC which, in order to protect
its own reputation for quality, has moved towards depicting
climate change stories in a way that reflects the scientific
opinion. That means the 3% of qualified scientists who are
sceptical get 3% of the attention. That's called balance,
and as a result Rodney would only be able to publish stuff
he's actually researched".

Herald's summer focus on science
The Herald recently ran a series of articles exploring 'Science that will change our lives', authored by science reporter Jamie Morton.
The six-part series highlighted a number of research projects currently underway around the country, whose discoveries are affecting our lives. The topics ranged from developing molecules to fight viruses, to tackling poor nutrition, and something about clothes.
The series starts off with a look at New Zealand's obesity epidemic, and research that is finding ways to improve nutrition. The 5-year international collaborative study is being lead by University of Auckland Professor Cliona Ni Mhurchuis, which will be using a smartphone application to test nutrition labelling on Kiwi household shoppers' purchasing behaviour.
Massey University senior Lecturer Dr Austen Ganley has been further unravelling the human genome, revisiting areas which were left unfinished when the sequence was originally released more than 10 years ago. The findings have opened up new areas for exploring potential causes of cancer.
The series also covers a 'biological paint' which has been developed by AUT's Professor Steve Henry, and is expected to be used in all diagnostic laboratories around the world within a decade.
The HIT Lab's Dr Mark Billinghurst talks augmented reality developments such as Google Glass and Otago University Vice-Chancellor Professor Harlene Hayne explains research looking into children's memory. Dr Benjamin O'Brien, from the University of Auckland looks at and advances in controlling artificial muscles and wearable technology.

Some of the research papers making headlines this week.
mountains fight climate change: Tectonic forces
lift NZ's Southern Alps at one of the fastest rates of any
mountains in the world. Scientists studying soil weathering
-- the process by which carbon is removed from the air and
locked away in dirt -- have found this also happens more
rapidly in the Alps than anywhere previously studied. Their
results overturn earlier ideas that rapid erosion prevents
such mountains from acting as carbon sinks, and has
implications for climate scientists' stock take of global
bird patterns: Birds flying in "V"-shaped formation
adjust their position and time the beating of their wings
with a degree of precision previously thought too complex to
manage, international research has found. The carefully
orchestrated patterns, observed for the first time in wild,
migrating birds, are thought to reduce the birds' energy
costs and indicate that birds have a remarkable awareness of
and ability to sense or predict the patterns of air
turbulence caused by nearby flock-mates.
cancer in older women: A UK study suggests that
screening women for cervical cancer beyond age 50 clearly
saves lives and adds there are benefits for women with
negative screening results to continue screening up to the
age of 69 years.
Crayfish need no-take
zones to flourish: Research in Wellington's
Taputeranga Marine Reserve shows that rock lobster,
historically four times more abundant and a keystone species
on the South Coast, are likely to bounce back under the
reserve's total protection from fishing -- but their
recovery process is predicted to take as long as 40 years.
The authors say that while the area's lobster fishery is
well-managed and sustainable from a single-species
perspective, their results show that total lobster numbers
have dropped low enough to have major impacts on the wider
temperate reef ecosystem, and no-take marine reserves are
essential to reverse this.
Endocrine-disrupting chemical swap: A US partial ban on phthlates -- plastic softening chemicals that have been linked to hormonal and developmental disturbances -- has had some potentially undesirable knock-on effects. Researchers studying exposures to phthlates over a decade have found significantly lower rates of exposure for both banned versions of the chemicals (DEHP, BBzP, DnBP) and those targeted by consumer advocacy groups (DEP), but much higher rates for lesser-known phthlates that industry has now begun using as substitutes, whose health effects remain largely unstudied.
