COPENHAGEN: Greenland’s ice sheet melted 17 times faster than the past average during a May heatwave that also hit Iceland, the scientific network World Weather Attribution (WWA) said in a report Wednesday.

The Arctic region is on the frontline of global warming, heating up four times faster than the rest of the planet since 1979, according to a 2022 study in scientific journal Nature.

“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, told reporters.

“Without climate change this would have been impossible,” said Otto, an associate professor in climate science at the Imperial College London.

The data from the May 15-21, 2025 heatwave was compared to the average ice melt for the same week during the period 1980-2010.

In Iceland, the temperature exceeded 26 degrees Celsius (79 Fahrenheit) on May 15, unprecedented for that time of year on the subarctic island.

“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.

In May, 94 percent of Iceland’s weather stations registered record temperatures, according to the country’s meteorological institute.

In eastern Greenland, the hottest day during the heatwave was about 3.9C warmer 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.

For Greenland’s indigenous communities, the warmer temperatures and melting ice affect their ability to hunt on the 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.

In Greenland, the higher temperatures coupled with heavy rainfall can have numerous consequences on nature.

In 2022, higher temperatures caused the permafrost to thaw, releasing iron and other metals into numerous Arctic lakes, it said.

Health and hygiene can also be affected, as rural Greenlandic households often lack sewage systems.

MANILA: House of Representatives prosecutors said Wednesday that Philippine Vice President Sara Duterte’s impeachment trial could not be stopped despite the Senate sending the case back to them hours after convening as a court.

Prosecutors told an afternoon press briefing their case had complied strictly with the constitution, adding they would seek clarification over what they called “confusing” Senate orders.

Duterte was impeached in early February on charges of graft, corruption and an alleged assassination plot against former ally and running mate President Ferdinand Marcos.

A guilty verdict would see her removed from office and permanently barred from politics.

“No one can stop this anymore, because jurisdiction has been acquired already by the impeachment court,” said Congresswoman Gerville Luistro, pointing to the Senate’s issuing of a summons for Duterte late Wednesday night.

“There will be no... withdrawal (of the impeachment case) by the House. That is not allowed by the constitution.”

Tuesday night’s 18-5 Senate vote ordered the House to certify it had not violated the constitution by hearing three impeachment complaints before the one that ultimately went to a vote.

The constitution bars subjecting anyone to multiple impeachment proceedings within the same year.

But House member Ysabel Maria Zamora said the final impeachment complaint had “consolidated all the articles” of the first three into one.

A second order to guarantee the case would move forward after new House members take their seats on June 30 was “impossible” to fulfil as they could not speak for a future Congress, prosecutors said.

Outside the Senate, several hundred protesters gathered Wednesday, shouting slogans and pounding on the gates as they called for the body to follow through with the impeachment trial.

The Senate’s vote to remand was as much a matter of “political survival” as anything, lawyer and former senator Leila de Lima said Wednesday.

De Lima, who warned more than a week ago the Senate could move to kill the impeachment, said the specter of a still-powerful Duterte was likely on lawmakers’ minds.

“Loyalty, friendship, political survival. Maybe they are thinking the Dutertes are very much around even if the patriarch (ex-president Rodrigo Duterte) is in The Hague,” she said.

The elder Duterte has been imprisoned since March when he was arrested and transferred to the International Criminal Court to face charges tied to his deadly drug war.

His daughter has been widely mooted as a presidential candidate in 2028 should she survive the impeachment process.

Senators “were trying to protect their political ambitions,” agreed Congresswoman France Castro, who endorsed an early impeachment complaint against the vice president.

Asked at Wednesday’s press briefing if he believed the Senate was deliberately delaying the trial, Congressman Keith Flores said the answer was clear.

“I cannot speak for everyone but for me, yes.”
