Trump pulls out of climate change deal

American President Donald Trump has made a big decision on climate change.

In 2015, there was a huge international agreement to do something about climate change from nearly 200 world leaders.

Among them was Barack Obama, who was the US president at the time.

Only two countries chose not to sign the deal, and now Trump has announced he's pulling the US out of it too.

But leaders across the planet have reacted with anger and disappointment.
