New Zealand is renowned for its wondrous scenery, and among the country's top tourist attractions are two glaciers that are both stunning and unusual because they snake down from the mountains to a temperate rain forest, making them easy for people to walk up to and view.
 
But the Fox and Franz Josef glaciers have been melting at such a rapid rate that it has become too dangerous for tourists to hike onto them from the valley floor, ending a tradition that dates back a century. With continuing warm weather this year there are no signs of a turnaround, and scientists say it is another example of how global warming is impacting the environment.
 
Tourism in New Zealand is booming and nearly 1 million people last year flocked to get a glimpse of the glaciers and the spectacular valleys they've carved. But the only way to set foot on them now is to get flown onto them by helicopter.
 
Tour operators offer flights and guided glacier walks, although logistics limit this to 80,000 tourists per year, half the number that once hiked up from the valley floor. Up to another 150,000 each year take scenic flights that land briefly at the top of the glaciers.
 
Flying in the UNESCO World Heritage area comes with its own risks, highlighted in November when a sightseeing helicopter crashed onto the Fox Glacier, killing all seven aboard.
 
Sitting near the base of the Franz Josef Glacier, Wayne Costello, a district operations manager for the Department of Conservation, said that when he arrived eight years ago, the rock he was perched on would have been buried under tons of ice. Instead, the glacier now comes to an end a half-mile further up the valley.
 
"Like a loaf of bread shrinking in its tin, it's gone down a lot as well," Costello said. "So it's wasted away in terms of its thickness, and that's led to quite a rapid melt."
 
Because of that melt, the valley walls that were once braced by the glaciers have been left exposed and vulnerable to rock falls, making hiking up too dangerous. Tour operators stopped taking guided hikes onto the Franz Josef in 2012 and the nearby Fox in 2014.
 
A 2014 paper published in the journal Global and Planetary Change concluded the two glaciers have each melted by 1.9 miles in length since the 1800s, making them about 20 percent shorter. The glaciers have recently been melting at a faster pace than ever previously recorded, the authors said.
 
Heather Purdie, a scientist at the University of Canterbury and lead author of the paper, said climate change is the driving factor.
 
"We know that glaciers around the world, including the Fox and Franz Josef glaciers, are responding to that warmer temperature and they're retreating," she said. Small changes in temperature and snowfall tend to be magnified in the two glaciers and their retreat has been interrupted by advances that can last years, she said.
 
Costello and tour operators are hoping to see another advance soon. But there's no sign of that: February was the second-hottest month ever recorded in New Zealand.
 
The hot weather has even created a new type of tourist attraction over the other side of the mountains. Purdie said the glaciers there are also rapidly retreating, resulting in tourists taking boat rides on the lakes to see some of the massive icebergs that have begun to shear away.
 
A helicopter trip onto the Fox Glacier reveals deep crevasses in the translucent blue ice and stunning ice caves through which guides take crampon-wearing tourists.
 
At the base of the Franz Josef, Dutch tourist Dieuwke Derkse said she was overwhelmed by the beauty of the glacier and the purity of the environment.
 
She said she felt a little guilty even visiting New Zealand because of the fossil fuels burned by the plane ride there. But she said the glacier also helped inspire her to live in a more environmentally conscious way.
 
"It makes me a little bit sad because you see how fast everything is going," she said.

    The impact that the glaciers have on New Zealand's economy is that they attract millions of tourists. So the question asks me what impact the glaciers have on New Zealand's economy. Well I say that the glaciers are more so an economic crutch and without them, New Zealand's economy would tank.

    The thing that the glaciers have on the economy is that the only way to get to it is by helicopter and most people don't have that much money.

    The impact the glaciers have on New Zealand's economy is good because the melting glaciers is making more tourism attractions.

    The impact that the glaciers has on the New Zealand's economy is because the article says "Because of that melt, the valley walls that were once braced by the glaciers have been left exposed and vulnerable to rock falls, making hiking up too dangerous." So the melting of the glaciers makes it more likely for rocks and things to fall and hurt someone or even kill them.

    The impact of the glaciers have on New Zealand's economy is that only a certain amount of people will be able to go see the glaciers, and that means less money.

    The glaciers are one of the things that are known for New Zealand's scenery and without the glaciers New Zealand's economy would become less effective.

    The glaciers impact the economy by making it go up. With all of the tourism, there will be a lot more money.

    The glaciers attracts many tourists each year, which has a positive impact on New Zealand's economy. However, as the glacier melts and becomes more and more dangerous for tourists to walk up to, less tourists are taking the helicopter to view the glaciers, which brings the economy down.

    The impact that the glaciers have on New Zealand's economy is that less tourists are coming to see the glaciers because it is getting harder to get to them and the tourists help the economy.

    The impact that the glaciers have on New Zealand's economy are the glaciers make tourist come visit New Zealand and that is a large source of money. People use to be able to walk up to the glaciers and see them but know it's to dangerous.
