As the global climate crisis intensifies, the looming threat of sea-level rise demands increasingly accurate and actionable projections.<\/h2>\n

A study led by researchers from Nanyang Technological University, Singapore (NTU Singapore), and Delft University of Technology, Netherlands (TU Delft), offers a more reliable approach to forecasting rising sea levels.<\/p>\n

Utilising an innovative \u2018fusion\u2019 method, the team projects that under a high-emission scenario, global sea levels could rise between 0.5 and 1.9 metres by 2100, significantly exceeding previous estimates.<\/p>\n

Why current sea-level projections fall short<\/h3>\n

Traditional models for predicting sea-level rise rely on a mix of well-understood phenomena like glacier melt and more uncertain processes such as abrupt ice shelf collapses.<\/p>\n

These discrepancies lead to a wide variation in predictions, making it challenging to estimate the true extent of future risks.<\/p>\n

The United Nations Intergovernmental Panel on Climate Change (IPCC) has provided \u2018likely\u2019 ranges of sea-level rise, representing a 66% probability.<\/p>\n

However, these projections lack a \u2018very likely\u2019 range (90% probability), leaving decision-makers with incomplete data to plan for extreme outcomes.<\/p>\n

The NTU-led team developed the fusion method to fill this critical gap, which combines strengths from multiple existing models and integrates expert judgment.<\/p>\n

This novel approach offers a clearer picture of future sea-level rise, addressing uncertainties and providing a valuable resource for governments and urban planners.<\/p>\n

The fusion approach: A game-changer in sea-level science<\/h3>\n

The fusion method blends statistical techniques with expert assessments using data from the IPCC\u2019s Sixth Assessment Report.<\/a><\/p>\n

It incorporates projections with varying confidence levels, including both medium and low-confidence data, to capture extreme possibilities such as sudden ice sheet collapses.<\/p>\n

A weighting system ensures that more reliable data is prioritised, while lower-confidence estimates are also factored in to account for uncertainty.<\/p>\n

The findings reveal stark contrasts between scenarios:<\/p>\n
