WHY IS THE WEATHER CHANGING SO DRASTICALLY?

()

In 2018 we have seen the weather acting like crazy. some people predict that the end of the world is near. There are several incidences lately that have caught the medias attention about what if happening for example the rare snowing in the Algerian deserts. Some people may think it to be a miracle but what I think it really is the human activities that are carried out on this planet. I recently read an article talking about earths fate, many people think that the planet is going to suffer from global warming yet actually its going into the next ice age (global cooling) That explains why deserts are having snow.

Another incidence is in Kenya, the earth has starting to separate. People say that the African continent is going to split into two. Geologists have said that this won’t happen for another tens of millions of years. They have said that it is a natural phenomenon which is caused by a shift in the earths tectonic plates.
There are other incidences across the globe which are still happening that aren’t normal and are yet to be found out.
What do you think?
