Climate apocalypse is when our planet's climate is changing in a very dramatic way and it has big, bad effects on us humans and other living things. Basically, when our climate changes too much too quickly, it can cause a lot of very serious problems. For example, more extreme weather such as hurricanes and droughts, more floods, and rising sea levels can make it hard for people to live in some places, and it can make it hard for plants and animals to find the food, shelter, and other things they need to survive. It can also cause a lot of pollution and make it harder for us to breathe, which can make us sick. Climate apocalypse can make life hard for us and the other creatures who share our planet.
