Why are ocean temperatures rising and what are the effects?

The Earth is getting warmer, and that makes the ocean feel like it’s getting a big hug from the sun.

Imagine your favorite cup of hot chocolate, when you leave it on the table, it gets cooler over time. But if you keep adding more hot chocolate to it, it stays warm longer. That's kind of what is happening with our oceans. The Earth is like that hot chocolate, and the sun is like a big spoon stirring things up. When we burn coal, oil, or cut down trees, we're giving the Earth more "hot chocolate", making it warmer.

What happens when the ocean gets warmer

The ocean gets warmer because it's absorbing a lot of that extra heat, just like your cup absorbs the warmth from the hot chocolate. This makes sea animals feel uncomfortable, and sometimes they move to cooler places. It can also make storms bigger and stronger, like when you blow on a flame in a candle, it flickers more.

Also, when water gets warmer, it expands, which means the sea level can rise, like when you put ice cubes in your drink and they melt and take up more space.

Examples

  1. Imagine the ocean as a big bathtub that’s getting warmer because we’re adding more heat from burning fuel.
  2. If you leave your car in the sun all day, it gets really hot inside, similarly, oceans are absorbing extra heat from the Earth.
  3. Warming oceans cause coral reefs to get stressed and might even turn white.
