The Earth is the EArth. Earthquakes, floods, hurricanes, etc, have been going on since day one. Only difference, a hundred years ago if you got a natural disaster in your area, that was it. You couldn't turn on CNN and see, oh, they had one in Peru too, and they had one in New Zealand, and what is going on?
There is a PERCEPTION that more of these are happening, because we all hear about all of them instantly.
