  • Glaciers in Europe's Alps Mountains are becoming more unstable and dangerous because of rising temperatures linked to climate change.
  • 2
  • A glacier is a large body of ice that slowly moves down a mountain or over a wide area of land.
  • 3
  • The warming of the earth's atmosphere is reawakening what were considered inactive ice masses.
  • 4
  • Italy has experienced early and severe summer heat.
  • 5
  • Many people are concerned about the effects of a severe lack of rain on crops in the Po Valley.
  • 6
  • In the Dolomite Mountains, a glacier recently collapsed on the Marmolada peak.
  • 7
  • At least seven people died. Many others are missing.
  • 8
  • "This summer 2022 risks being the perfect storm for glaciers," said Giovanni Baccolo.
  • 9
  • He is an environmental scientist and glacier expert at Milan-Bicocca University.
  • 10
  • Baccolo noted a lack of winter snow and a hot start to the summer affecting glaciers.
  • 11
  • "Nobody could have expected a glacier like the Marmolada to react like this," he told Reuters.
  • 12
  • "It is a kind of climatic fossil, glaciers like the Marmolada are considered 'placid.'"
  • 13
  • Placid is a term that means calm and peaceful.
  • 14
  • Temperatures on the normally freezing Marmolada reached 10 degrees Celsius on Saturday, Veneto area governor Luca Zaia said.
  • 15
  • "High elevation glaciers such as the Marmolada are often steep and relying on cold temperatures below zero degrees Celsius to keep them stable," said Poul Christoffersen.
  • 16
  • He is a professor at the University of Cambridge who studies glaciers.
  • 17
  • Christoffersen said that climate change melts more water, "which releases heat that warms up the ice if the water re-freezes."
  • 18
  • He added that a worse effect would be the lifting of the glacier from the rock below, "causing a sudden unstable collapse."
  • 19
  • Baccolo said that climbers heading into the mountains to escape the summer heat should be careful about where they go.
  • 20
  • "The invitation I want to make to those who go to the high mountains this summer is to use much more caution," he said.
  • 21
  • "The problem is that it may no longer be enough to read the signs from the glacier that have been read so far," he added.
