Iceland is heading to the polls for an election that could see nine out of ten political parties winning seats in the parliament, potentially making it harder for the future government to find common ground on pressing issues such as climate change.

Above all else, climate change was at the top of the agenda during the campaign trail, with some parties trying to take more urgent action and others claiming that Iceland could stand to benefit from it.

Many left-leaning parties campaigned on promises to cut the country's carbon emissions further than previously agreed under the Paris Climate Agreement.

Iceland already has an aggressive climate change policy compared to other European countries. It plans on being carbon neutral by 2040, a decade before its peers.

However, some parties announced plans that were previously unheard of before the election. The Socialist Party is offering anyone who wants it a job planting trees. The Pirate Party wants to encourage plant-based diets. And Vidreisn, a center-right party, said it would declare a climate emergency if it won. 

This is because Iceland is increasingly feeling the effects of climate change. This past summer, between June and August, the country saw 59 days above 20 degrees Celsius.

It has also seen a dramatic decrease in glacial cover, around 800 sq km melted over the past 20 years. That's around the size of New York City. 

However, not everyone thinks that these changes will necessarily be a bad thing for the country. The state-owned national energy company said that its water capacity for its hydro-dams increased by around 8 percent because of melting glaciers.

And an Icelandic farmer named Hermann Gunnarsson told AP that this year's harvest was the best he has ever had. 

"The climate coin has two sides," he said. "But the politicians who talk the most about climate change are afraid to speak about the benefits, too."

And while three of the nine parties running have pledged to stop the construction of new energy plants in the country, David Gunnlaugsson, head of the center right party Midflokkurinn Sigmundur, argued that it's better to produce energy domestically because Iceland uses renewable energy.

"More production in Iceland is good for the planet and will at the same time improve our standards of living," he said.

The coming election could also see an end to stability after the country went to the polls five times during the decade before 2017 when the current coalition government took power. 

After that election, the government was run by an unprecedented partnership between the Left-Green Movement, the center-right Progressive Party and the pro-business Independence Party.

And while the head of the coalition, Prime Minister Katrín Jakobsdóttir, has largely been popular since she took power, she may not win another term as her party, the Left-Green Movement, is currently trailing in the polls.

It is only expected to gain 10 to 12 percent of the vote on Saturday.

The polls will close on Saturday at 10:00 pm GMT.
