Sea Levels Rising Significantly Worldwide: What Coastal Communities Need to Know

Sea levels are rising worldwide, threatening coastal communities. Manila has seen a 40 cm increase in the past 30 years, with more rises expected by 2100. Understanding and adapting to these changes is crucial.

Sea Levels Rising Significantly Worldwide: What Coastal Communities Need to Know

Sea levels are rising significantly worldwide, with no continent spared, as shown by data from a British agency collecting tide levels since 1933. Satellite measurements, initiated in 1993, confirm this trend. Coastal communities and lower-lying regions are disproportionately affected.

In the past 30 years, Manila has seen a 40 cm increase in sea levels. This rise is expected to continue, with IPCC predicting a global increase of 20 to 80 cm by 2100. The current research estimates ice melt could contribute 0.3 to 1 meter by then, with uncertainty due to emissions and ice sheet dynamics.

Not all areas are affected equally. In Scandinavia, land rise in some ports keeps them high and dry despite sea level increases. The Earth's crust expansion after glacier melt also causes land to rise in certain areas.

CORRECTIV has mapped 500 locations to illustrate past and future sea level changes. As the trend continues, understanding and adapting to these changes will be crucial for coastal communities worldwide.
