Mischievous Kea rearrange road cones on state highway

 

South Island kea are having fun with motorists by rearranging road cones on a popular tourist route.

The Kea Conservation Trust said the NZ Transport Agency's Milford Alliance team were puzzled to find their road cones in odd places on State Highway 94 at the Homer Tunnel, the entrance to Milford Sound.

After a few weeks they checked the footage from their cameras at each end of the tunnel and made a remarkable, and hilarious, discovery - it was cheeky kea.

The video, labelled The Kea Movie, starts with the road clear of any road cones before a kea can be seen dragging one onto the left hand lane. 

Another one then appears being brought into the middle of the road as cars weave around them, before the Kea again pops out and moves the cone again.

A third road cone is then brought out onto the road and the mischievous kea continue to rearrange the cones, popping out of sight as traffic goes by, before darting out and moving them again.

NZ's sinking and rising landscape

Parts of New Zealand are sinking at faster rates than others and rising faster, a scientist says.

The just-published tectonic research provides new information about how different parts of New Zealand are either rising or subsiding in relation to the centre of the earth.

Data was collected by GeoNet's GPS recorders between 2000 and 2015, and the first map has been produced of relative vertical movements of the Earth's surface based on measurements at 189 places across the country.

Analysis of the data shows that parts of New Zealand, like the North Island's east coast, have subsided by as much as 3mm a year for the past 15 years.

This means this region is effectively subjected to a maximum sea level rise of up to 6mm a year, which is twice the global average.

Co-author Professor Tim Stern, of Victoria University's School of Geography, Environment and Earth Sciences, said other parts of New Zealand were rising.

"For example, along parts of the Bay of Plenty coast, the Whanganui coast and south to the Kapiti region, and along the Otago, Westland and Southland coastlines, there are small rises of 1mm per year or less."

This meant sea level rise in these areas would be less than the global average.

"The data also show inland areas of the South Island and the Southern Alps are rising by up to 6mm per year, while in the Rotorua area there is a remarkable subsidence rate of 15 mm per year.

Kaikoura Quake: How has wildlife fared?

Recent sightings of whales, as well as Hector's and Dusky dolphins, off the coast of Kaikoura have brought immense relief to locals and tour operators.

Forest and Bird marine advocate Anton van Helden was optimistic about the welfare of Kaikoura's many deep-diving species - among them sperm whales, humpback whales, Southern right whales, orca and several dolphin species.

While the submarine Kaikoura Canyon provided a productive ecosystem for whales and dolphins, there were similarly productive habitats elsewhere that could have served as alternatives.

But he expected that, even with considerable uplift around the canyon area - and the potential of landslides - the systems would have been easily large enough to sustain the quake's effects.

"The other thing, with sperm whales, it is only males that would effectively be there at the moment, so this is the time of year when there would be fewer of them in the region."

However, early indications showed Kaikoura's resident fur seals would have fared worse.

At Ohau Point, a large slip had caused heavy damage to a specially protected seal sanctuary, and it was likely some animals would have perished.

"It's too soon to be able to know the full impact that the earthquake will have had on the local population," Department of Conservation science adviser Laura Boren said.

Scientists scratch their heads over Arctic winter

Political people are watching the chaos in Washington at the moment. But some people in the science community are watching the chaos somewhere else - the Arctic.

It's polar night there now - the sun isn't rising in much of the Arctic. That's when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

But in fall 2016 - which has been a zany year for the region, with multiple records set for low levels of monthly sea ice - something is totally off. The Arctic is super hot, even as a vast area of cold polar air has been displaced over Siberia.

At the same time, one of the key indicators of the state of the Arctic - the extent of sea ice covering the polar ocean - is at a record low right now. The ice is freezing up again, as it always does this time of year after reaching its September low, but it isn't doing so as rapidly as usual. In fact, the ice's area is even lower than it was during the record-low 2012.

Twitter's expert Arctic watchers are stunned. Zack Labe, a PhD student at the University of California at Irvine who studies the Arctic, tweeted out an image on Thursday from the Danish Meteorological Institute showing Arctic temperatures about 20C higher than normal above 80 degrees north latitude.
"Today's latest #Arctic mean temperature continues to move the wrong direction ... up. Quite an anomalous spike!," Labe wrote.

"Despite onset of #PolarNight, temperatures near #NorthPole increasing. Extraordinary situation right now in #Arctic, w/record low #seaice," added Daniel Swain, a climate scientist at UCLA.

This is the second year in a row that temperatures near the North Pole have risen to freakishly warm levels.

The North Pole is an insane 20 degrees warmer than normal as winter descends

Set for another year of record heat

This year is on track to be the hottest on record, the United Nations forecast yesterday.

Scientists, meanwhile, reported that greenhouse-gas emissions from burning fossil fuels, the main driver of global warming, remained constant for the third year running last year, while the World Bank calculated that 26 million people slip into poverty annually due to natural disasters, reflecting the risks posed by climate change.

All three reports were issued on the sidelines of high-level United Nations climate talks in Marrakesh still reeling from news that Donald Trump, who denies climate change, had captured the White House.

The fact that economic growth and CO2 pollution no longer move in lock-step is an encouraging sign, the scientists said.

Climate warning despite carbon emissions levelling off

Carbon emissions from burning fossil fuels have been nearly flat for three years in a row - a "great help" but not enough to stave off dangerous global warming, a report said yesterday.

Emissions of planet-warming carbon dioxide stayed level last year at 36.3 billion tonnes (GtCO2) and were projected to rise "only slightly", by 0.2 per cent this year, according to the annual Global Carbon Budget report compiled by teams of scientists from around the world.

"This third year of almost no growth in emissions is unprecedented at a time of strong economic growth," said research leader Corinne Le Quere of the University of East Anglia.

Driven largely by reduced coal use in China, this was a "clear and unprecedented break" with the preceding decade's fast emissions growth, at a rate of some 2.3 per cent per year from 2004 to 2013, before dipping to 0.7 per cent in 2014.

"This is a great help for tackling climate change but it is not enough," said Le Quere.
For the world's nations to make true on the global pact to limit average global warming to 2C over pre-Industrial Revolution levels, emissions must do more than level off, the study found.
A decrease of 0.9 per cent per year was needed to 2030.

The concentration of greenhouse gases in the atmosphere has continued to grow, the report warned, hitting a record level of 23 GtCO2 last year that looked set to reach 25 GtCO2 in 2016.
