Recent reports from leading climate organizations warn of unprecedented global temperature increases and accelerating sea level rise over the next five years. The World Meteorological Organization (WMO) forecasts an 80% chance that at least one year between 2025 and 2029 will set a new heat record, with global temperatures exceeding 1.5°C above pre-industrial levels—a critical threshold outlined in the 2015 Paris Agreement.
These rising temperatures are expected to intensify extreme weather events, including heatwaves, heavy rainfall, droughts, and contribute to significant ice melt and ocean heating. Notably, the Arctic region is projected to warm at more than three times the global average, accelerating ice loss and contributing to sea level rise.
Impact on Coastal Cities
Sea level rise poses a significant threat to coastal communities worldwide. A recent study indicates that even with a 1.5°C temperature increase, we could witness "catastrophic inland migration" due to rising seas. Ice loss from Greenland and Antarctica has quadrupled since the 1990s, becoming the primary driver of sea level rise.
NASA's analysis reveals that in 2024, the global sea level rose faster than anticipated, primarily due to ocean water expanding as it warms—a phenomenon known as thermal expansion.
Geographical Overview: Seas, Oceans, Continents, Countries, and Cities

Countries Bordering Multiple Oceans:
Some countries have coastlines along more than one ocean, which can influence their climate and trade. For a detailed list, refer to Wikipedia.
Major Coastal Cities at Risk:
- New York City, USA
- Tokyo, Japan
- Shanghai, China
- London, UK
- Dhaka, Bangladesh
These cities are among the most vulnerable to sea level rise due to their large populations and coastal locations.
