Study Suggests Global Warming Could Trigger Ice Age

Scientists have found that global warming might actually lead to an ice age in the future.

They discovered a new way Earth's climate can change.

Normally, rocks and rain help keep the planet's temperature steady by absorbing carbon dioxide.

But sometimes, this process can go too far.

When the planet gets warmer, more nutrients like phosphorus wash into the oceans.

These nutrients help tiny plants called plankton grow.

When plankton die, they take carbon with them to the ocean floor.

This can lower the amount of carbon dioxide in the air, making the planet cooler.

In the past, this made ice ages much worse.

Today, the effect is weaker, but it could still bring an ice age sooner than expected.

However, this won't happen for a very long time, so we still need to focus on stopping current warming.
