The polar sea ice hit its lowest extent for July in 40 years. The Arctic has been warming at least twice as fast as the rest of the world for the last 30 years, an observation referred to as Arctic amplification. He and his colleagues published the study Thursday in the Nature Communications Earth & Environment journal.
“Greenland is going to be the canary in the coal mine, and the canary is already pretty much dead at this point,” said glaciologist Ian Howat at Ohio State University. This process, however, would take decades. If all of Greenland’s ice goes, the water released would push sea levels up by an average of 6 meters – enough to swamp many coastal cities around the world. That melting is already causing global seas to rise about a millimetre on average per year. Scientists studied data on 234 glaciers across the Arctic territory spanning 34 years through 2018 and found that annual snowfall was no longer enough to replenish glaciers of the snow and ice being lost to summertime melting. Greenland’s ice sheet may have shrunk past the point of return, with the ice likely to melt away no matter how quickly the world reduces climate-warming emissions, new research suggests. It lasted five months.Please log in to bookmark this story. The last eruption on all the Canary Islands occurred underwater off the coast of El Hierro island in 2011. The last eruption on La Palma 50 years ago lasted just over three weeks. Itahiza Dominguez, head of seismology of Spain’s National Geology Institute, told Canary Islands Television that although it was too early to tell how long this eruption would last, prior eruptions on the Canary Islands lasted weeks or even months. “People should not come near the eruption site where the lava is flowing,” “We are having serious problems with the evacuation because the roads are jammed with people who are trying to get close enough to see it,” Hernández said. Hernández, the La Palma mayor, asked people to stay away from the eruption. At their nearest point, the islands are 100 kilometers (60 miles) from Morocco.Ī 4.2-magnitude quake was recorded before the eruption, which took place in an area known as Cabeza de Vaca on the western slope as the ridge descends to the coast.Īs the eruptions continued, at least two open mouths belched bright red magma into the air that then flowed in tight streams down the mountain slope. La Palma, with a population of 85,000, is one of eight volcanic islands in Spain’s Canary Islands archipelago off Africa’s western coast. The rest were in shelters, officials said. Most of those evacuated found family or friends to take them in.
Huge red plumes topped with black-and-white smoke shot out along the Cumbre Vieja volcanic ridge, which scientists had been monitoring following the accumulation of molten lava below the surface and days of small earthquakes. near the southern end of the island, which saw its last eruption in 1971. The Canary Islands Volcanology Institute reported the initial eruption shortly after 3 p.m. The volcano erupted Sunday after a weeklong buildup of seismic activity that was closely monitored by authorities.
Spanish Prime Minister Pedro Sánchez was due to visit the affected area Monday after canceling his trip to New York to attend the U.N. People on La Palma largely live from farming. The Military Emergencies Unit is increasing its deployment on La Palma to 180 soldiers and 57 vehicles, backed up with three water-dropping aircraft due to arrive later Monday.Įxperts said the eruption could last for weeks or even months. He said a wall of lava 6 meters (20 feet) high “is consuming houses, infrastructure, crops in its path to the coast,” state news agency Efe reported. Mariano Hernández, the major of the town of Cabildo, described the scene in the area affected by the lava as “bleak.” Town Mayor Noelia García said people had been evacuated from houses all the way down to the shoreline. The lava crept into the town of Los Llanos de Aridane, which lies close to the volcano.
