UN Calls for Urgent Action on Rising Sea Levels
Understanding Rising Sea Levels
Rising sea levels mean that the ocean water is getting higher over time. This is happening faster than ever before, mainly because of climate change. The Pacific region, where Tonga is located, is seeing some of the fastest rises in sea levels, with some places experiencing rates more than twice the global average. The two main reasons for this are:
- Warmer Oceans: As the ocean water gets warmer, it expands and takes up more space.
- Melting Ice: Glaciers and ice sheets in places like Antarctica and Greenland are melting, adding more water to the oceans.
How Does This Affect Coastal Communities?
Rising sea levels have several harmful effects on communities living near the coast, including:
- More Storm Surges: Storms can push the higher ocean water onto the land, causing severe flooding.
- Coastal Flooding: Higher sea levels mean that coastal areas are more likely to flood, even without storms.
- Saltwater Intrusion: Seawater can seep into freshwater supplies, making it hard for people to get clean drinking water.
These problems threaten people’s homes, livelihoods, and the natural environment in vulnerable regions.
Guterres’ Call for Global Action
Guterres urged world leaders to act quickly to address this crisis. He emphasized four key actions:
Reduce Greenhouse Gas Emissions: These are the gases that contribute to global warming and climate change.
Phase Out Fossil Fuels: Fossil fuels, like coal and oil, are major sources of greenhouse gases.
Invest in Renewable Energy: Energy sources like solar and wind power don’t produce greenhouse gases.
