Retreat of glaciers since 1850

Have you ever seen a big snowman that someone made in the winter time? Glaciers are like really, really big snowmen made of ice! They are formed when snow falls in a really cold place and piles up over time.

Now, imagine if that snowman started to melt but the snow kept falling on top of it. The snowman would slowly start to shrink and get smaller, right? That's kinda like what's happening to glaciers.

Since 1850, the Earth has been getting warmer because of something called climate change. This means that it's not as cold as it used to be in some places where glaciers are found. As a result, glaciers all over the world have been getting smaller and smaller.

So, just like that snowman melting in the sun, glaciers are melting too. This is because warmer temperatures cause the ice to melt faster than it can freeze, and so over time, glaciers retreat or move backwards like it's getting smaller and smaller.

The retreat of glaciers is something that scientists are watching really closely because it can have big effects on our planet. It can cause sea levels to rise, change ecosystems, and impact the weather in different parts of the world. That's why it's important that we work to take care of our planet, so that we can stop the glaciers from melting away completely!
