PTIGreenland's ice sheet has melted 17 times faster than average during the heatwave in May, scientific network World Weather Attribution (WWA) said in a report Wednesday.
According to a 2022 study in scientific journal Nature, the Arctic region has heated up four times faster than the rest of the planet since 1979.
"The melting rate of the Greenland ice sheet by, from a preliminary analysis, a factor of 17... means the Greenland ice sheet contribution to sea level rise is higher than it would have otherwise been without this heat wave," one of the authors of the report, Friederike Otto, associate professor in climate science at the Imperial College London, told the media.
"Without climate change this would have been impossible," she said.
The temperature in Island exceeded 26 degrees Celsius on May 15, which is an extremely rare phenomenon for the region.
"Temperatures over Iceland as observed this May are record-breaking, more than 13 degrees Celsius hotter than the 1991-2020 average May daily maximum temperatures," the WWA said.
Further, 84 per cent of the country's weather stations registered record temperatures in May, according to the meteorological institute.
In eastern Greenland, the hottest day during the heatwave was 3.9 degrees Celsius higher compared to the preindustrial climate, the WWA said.
"While a heatwave that is around 20 degrees Celsius might not sound like an extreme event from the experience of most people around the world, it is a really big deal for this part of the world," Otto said.
"It affects the whole world massively," she said.
According to the WWA, the record highs observed in Iceland and Greenland this May could reoccur every 100 years.
The warmer temperatures mean that Greenland's indigenous communities are losing their ability to hunt on ice, posing a threat to their livelihood and traditional way of life.
The changes also affect infrastructure in the two countries.
"In Greenland and Iceland, infrastructure is built for cold weather, meaning during a heatwave ice melt can lead to flooding and damage roads and infrastructure," the WWA said.
