The melting of all land ice on Earth due to climate change poses a significant threat, potentially leading to catastrophic sea level rise that would drastically alter coastlines worldwide.

The Antarctic and Greenland ice sheets, which cover over 6 million square miles, hold enough fresh water to raise global sea levels by approximately 200 feet if they were to fully melt.

The ongoing release of greenhouse gases is the primary driver of climate change, resulting in the accelerated melting of ice and subsequent sea level rise.

If all land ice melts, cities across Africa, the Middle East, Asia, and South America will face severe flooding, displacing millions from their homes.

A recent video by Business Insider Science illustrates potential future coastlines if the Antarctic and Greenland ice sheets were to completely melt, submerging major coastal cities.

Rising global temperatures, fueled by carbon emissions from fossil fuel use, are causing land ice to melt at an unprecedented rate, threatening to push ice sheets past a critical tipping point.

Immediate action to reduce carbon emissions is essential to prevent the irreversible melting of ice sheets and mitigate catastrophic changes to ecosystems and human societies.

In North America, iconic cities like New York City, San Francisco, and Houston, along with the entire state of Florida, would be at risk of submersion.

Cities such as Brussels, Venice, and Miami are particularly at risk of disappearing underwater as a direct consequence of rising sea levels.

Major urban centers in Asia, such as Mumbai, Beijing, and Tokyo, would need to relocate inland due to rising water levels, creating a massive humanitarian crisis.
