Think of it as more and more energy being kept within a closed pace.
That closed space is the thin layer of land + ocean + lower atmosphere, it's spinning and it's quite large in comparison to single human.
Now think of a closed room with energy being pumped into that room, to (among other things) a fridge on the floor with door open.
The energy increase makes the heat exchange coils on the back of the fridge hotter and the space inside the fridge colder.
Overall the average energy within the room in increasing.
This is a poor but in some ways accurate picture of the earth .. or at least one climatic cell - the earth has a number of these in the North and South hemispheres and they interact and spill energy from one to the other.
Energy can express itself in many ways by cascade transfers - to wind and storms, to melting ice (at zero degrees) to create water (also at zero degrees).
In Australia that energy has driven the decadal scale La Niña and El Niño oscillation that, so far*, has worked out fairly well for Australia ... (a very catastrophic fire season a few years back aside).
Elsewhere on the globe, not so much for others.
But wait, there's more, especially in the longer term if steps aren't taken.
In the near term, you can expect Australia to see a hot, dry El Niño:
