Global Sea Levels Rising Faster Than Expected Warmest Year on Record Pushes Oceans to New Heights

Global sea levels rose at an alarming rate in 2024 surpassing previous predictions due to an unusual spike in ocean warming and melting land-based ice. According to a NASA led analysis the rate of rise last year was 0.23 inches (0.59 cm) per year, significantly higher than the expected 0.17 inches (0.43 cm) per year. Scientists attribute this sharp increase primarily to the thermal expansion of seawater process where ocean water expands as it warms. In a surprising shift, two-thirds of last year’s sea level rise came from thermal expansion reversing the usual trend where melting glaciers and ice sheets were the dominant contributors. Josh Willis sea level researcher at NASA Jet Propulsion Laboratory in Southern California say “The rise we saw in 2024 was higher than we expected, Ever...

Board Game Turns Tide on Sea Level Awareness Among Youth

Breaking News, Climate Actions

A new study reveals that a board game can significantly enhance young people's understanding of sea level rise and their ability to influence it. Over the past two years Utrecht University researcher Nieske Vergunst developed and tested the Sea Level Game assessing its impact on participants aged 16 to 25. The results show that players became more aware of climate change and more confident in making a difference. Vergunst created the game to address a gap in climate communication particularly for those with low science exposure. “Sea level rise affects us all and people have a right to understand it,” she explains. Players take on roles in two teams Sea Level and Solution Level facing real-world dilemmas that shape the future. Their choices influence whether sea levels rise drastically ...

New Study Warns of Potential 1.9 Metre Sea-Level Rise by 2100 Under High Emissions Scenario

Breaking News, Climate Actions, Disasters, Learning & Developments

An international team of researchers from NTU Singapore and Delft University of Technology (TU Delft) in the Netherlands has projected a significant rise in global sea levels if carbon dioxide emissions continue to increase. According to their findings, published in the scientific journal Earth's Future, sea levels could rise between 0.5 and 1.9 meters by the year 2100 under a high-emission scenario. The upper limit of this range is nearly 90 centimeters higher than the latest United Nations (UN) projection, which estimates a rise of 0.6 to 1.0 meters. This study provides a "very likely range" (indicating a 90% probability of occurrence), offering a new dimension to sea-level projections. Previously, projections from the UN's Intergovernmental Panel on Climate Change (IPCC) were based o...

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...

Assessing Coastal Vulnerability to climate and non-climate drivers: Major Concerns for Coastal residing mega cities

Breaking News, Climate Actions, Thoughts & Talks

Climate change is global phenomena, which impacting humanity form multi-dimensional way. The sea level rise is currently one of the most important climate change pressures along the coastal belt across the globe before the humanity. Recent reports and analysis says that, it is expected to continue rising and possibly accelerate during this century due to the increase in the average global surface temperature, and contributions from changes in ice sheet dynamics. The data analyzed by Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) that the sea level is projected to rise between the present (1980 to 1999) and the end of the 21st century (2090 to 2099) under the six SRES scenarios1 by between 18 and 59 centimeters. The global mean sea-level rise scenarios or p...

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 ...
