A recent study reveals that global sea levels are rising twice as fast as they did in the last century, now increasing by approximately 4.3 mm annually, compared to 1.8 mm at the turn of the 20th century. The study, involving laser technology and conducted during a critical decade for climate action, shows that climate measures are worsening at an accelerating rate. Lead author Professor Piers Forster noted the alarming consistency of these findings, despite a slight slowdown in the increase of greenhouse gas emissions.
The rising sea levels, driven by melting ice and thermal expansion due to a warming atmosphere, pose significant threats to coastal areas, particularly in the UK, where 100,000 properties are at risk over the next 50 years. In response, the UK government plans to invest £7.9 billion in flood protection to safeguard homes and infrastructure.
The report also highlights the urgent need to reduce greenhouse gas emissions significantly by 2024 to keep global warming below 1.5°C. It warns that only a small carbon budget remains to achieve this goal. Scientists are calling for enhanced climate policies ahead of the COP30 Climate Summit in Brazil in November, emphasizing the importance of data-driven decision-making to mitigate future climate impacts.
