What is sea ice:
Sea ice is frozen ocean water. It forms, grows, and melts in the ocean and is mostly found in the Arctic and Antarctic regions. Unlike icebergs or glaciers, which come from land, sea ice starts as water in the sea.
What happens if sea ice melts?
Earth gets warmer:
Sea ice reflects sunlight. Without it, dark ocean water absorbs more heat, making the planet warmer.
Strange weather
Melting sea ice can mess up winds and ocean currents. This can cause weird weather like heatwaves, heavy rain, or cold spells.
Animals lose homes
Polar bears, seals, and penguins need sea ice. If it melts, they may starve or die out.
Sea level rise (indirectly):
Sea ice melting doesn't raise sea levels, but it speeds up the melting of land ice (like glaciers), which does.
Affects people too
Coastal areas may face more storms, floods, or food problems. Arctic communities lose hunting and fishing grounds.
