UNESCO, WMO Unveil 2025 as Year for Glacier Preservation

UNESCO and the World Meteorological Organization (WMO) have declared 2025 the International Year of Glaciers’ Preservation (IYGP), emphasizing the urgency of addressing glacier retreat and its global implications. The initiative was officially launched on January 21, aiming to protect Earth's "water towers" essential sources of freshwater for over 2 billion people. The declaration follows a UN General Assembly resolution from December 2022, marking March 21 as World Day for Glaciers annually. With glaciers covering 700,000 square kilometers and storing 70% of the world’s freshwater, their rapid melting poses severe threats such as water scarcity, rising sea levels, and ecosystem collapse. WMO Secretary-General Celeste Saulo highlighted the severity of the crisis "In 2023, glaciers su...

Unraveling the ‘Ice-Ocean Boundary Layer’ to Predict Sea Level Rise

Breaking News, Learning & Developments

Scientists are making significant progress in deciphering the intricate relationship between the Antarctic ice sheet and the Southern Ocean, a dynamic that plays a crucial role in driving global sea level changes. Recent research highlights how small-scale oceanic processes, often occurring at the microscopic level, influence the melting of massive ice structures. Despite Antarctica’s vast ice reserves, the factors determining its stability are highly localized, presenting significant challenges in measurement and modeling. To overcome this, researchers are turning to advanced tools like autonomous underwater vehicles and cutting-edge computer simulations. These technologies are uncovering critical details about how ocean water interacts with the ice, offering new insights into previous...

Ice Cores data from Nevado Huascaran Provide Insights into Amazon Basin’s Climate History

Breaking News, Climate Actions

Scientists from Ohio State University (OSU) have studied ice cores from Nevado Huascaran, the world’s highest tropical mountain located in the Peruvian Andes, to gain unprecedented insights into the climate history of the Amazon Basin over the past six decades. Unlike polar regions, samples from tropical areas like Nevado Huascaran can provide valuable information about phenomena such as El Niño and the movement of monsoon winds. The research involved collecting ice core samples from the summit and the mountain col, the lowest point between two ridges. Key Points: •Nevado Huascaran, standing at nearly 7,000 meters above sea level, is the world’s highest tropical mountain. •Ice core samples were collected from the summit and the mountain col to analyze the impact of climate change ...
