While Hollywood's depiction of a white Christmas might be the northern hemisphere ideal, for many around the world the holiday is celebrated in very different weather. But, climate change is threatening both winter wonderlands and warmer Christmas traditions.

Whether it's decorating the Christmas tree with sparkly lights, building a snowman or carolling to your heart's content, we all have our favourite holiday traditions.

In the Netherlands, where I grew up, a popular tradition around Christmas is to put on your skates and take to the country's frozen ponds, canals and rivers. When it freezes, young and old head onto the ice. As my father says, "Skating is in our blood."

"You'll see very young children holding onto chairs as they scrabble along, as old people skate by hand-in-hand," he says, painting a verbal picture of a beautiful wintery landscape. "It's a truly magical scene."

Keen skaters used to enter the Elfstedentocht, which translates to the "eleven cities tour", an iconic ice skating race covering 200km (120 miles) that passes through 11 cities in the northern province Friesland. It's been 24 years since the last race took place. Climate change is endangering this beloved winter tradition.

When my father was at school he regularly enjoyed "ice days", when schools closed and everyone spent the day skating instead of studying. I only remember one such exhilarating moment during my teenage years.

And it is not just cold-weather holiday traditions that are slowly fading away. Around the world extreme weather caused by climate change and rising temperatures are altering beloved Christmas traditions. In the accounts below, BBC Future speaks to three young people from the Philippines, Puerto Rico and Brazil who share their stories of how the rapidly changing climate is transforming Christmas where they live.

The Philippines boasts the earliest and longest Christmas season in the world.

"They say that Filipinos celebrate Christmas the longest," says Mitzi Jonelle Tan, a 22-year-old climate activist from Manila, the capital of the Philippines. "We celebrate from 1 September until 6 January.

It is a colourful and creative time. People make their own Christmas decorations, including a star-shaped lantern, called a parol. They hang these bright lanterns in windows and streets for the entire festive season, from September until January.

"The parol is something that families create together using colourful, recycled plastic and little pieces of wood," says Jonelle Tan.

"On Christmas morning we always take photos in front of churches near where my mum grew up," she says. "My mum and grandpa also used to take pictures in front of these churches."

But in 50 years' time, this special place for the Jonelle Tan family could no longer exist due to rising sea levels. "It's scary as it's not that far away," she says.

The Philippines is the world's most vulnerable country to disasters caused by climate change. The country is hit on average by more than 20 typhoons each year, which cause severe flooding and large-scale destruction. These severe climate impacts are already changing Filipinos' Christmas experience.

In November last year, super typhoon Goni, the year's most powerful storm, hit the Philippines at 225km/h (140mph).

"People were stranded on rooftops and all the roads were flooded," recalls Jonelle Tan. "A few days before Christmas, we were still helping clean up the mud that had flooded the houses."
