Time travel murder needed

I see that the matter of whether it's ethical (or just a good idea) to go back in time and kill baby Hitler was on the internet recently (see the Vox explainer here); but I have a better idea - someone needs to consider going back in time to kill Dorothy Mackellar.   

If you are not Australian, you may need to be informed:  she was an Australian poet who wrote a piece beloved of primary schools of my era which nearly every Australian (at least over the age of 50) has had to learn. 

The problem:

I love a sunburnt country,
A land of sweeping plains,
Of ragged mountain ranges,
Of droughts and flooding rains.   

means that climate change deniers, like those that flood (ha, a bit of a topical pun) Catallaxy, think that the one line in there eans that they never have to admit that record breaking rains and associated floods in Australia are being worsened by climate change. 

OK, maybe she doesn't need to be killed.   Just someone get their hands on that pretty turgid piece of writing and tear it up.
