Global opvarmning

Mountains around the world are heating up more quickly than surrounding lowlands, according to a comprehensive study, leading to shifts in snow, rain, and water supplies that affect over a billion people. The research highlights elevation-dependent climate change, with temperatures rising 0.21°C per century faster in mountain regions. These changes pose risks to ecosystems, water resources, and human safety in areas like the Himalayas.

Earth's oceans reached their highest heat levels on record in 2025, absorbing 23 zetta joules of excess energy. This milestone, confirmed by an international team of scientists, underscores the accelerating impact of climate change. The warming trend, building since the 1990s, fuels stronger storms and rising sea levels worldwide.

Researchers have discovered that massive hidden underwater waves, triggered by iceberg calving, significantly intensify the melting of Greenland's glaciers. Using a 10-kilometer fiber-optic cable, an international team measured these waves for the first time. The findings reveal a powerful mixing effect that brings warm seawater into contact with glacier bases, accelerating ice loss.

Scientists have used cosmic dust to reconstruct 30,000 years of Arctic sea ice history, showing dramatic shifts tied to climate changes. The study, published in Science, links ice coverage to nutrient cycles and future ecological impacts. Findings highlight how declining ice could boost phytoplankton activity and alter food webs.
