Temperatures are Rising Down Under

The temperature hikes in Australia during their summer have been unbearable. According to The Sydney Morning Harold, New South Wales (a territory in Australia) has broken it’s sate-wide recorded temperatures for February - not once, but twice. “Before Friday, NSW had never had a February day above 42 degrees, based on averaged maximums in the state, according to the Bureau of Meteorology.” They were at 47.6 degrees Celsius which is 117.68 degrees Fahrenheit. They almost broke the record for hottest atmospheric temperature on terrestrial Earth. 

This is difficult for the people of Australia, infrastructure suffers, sporting events are threatened, and death counts rise. This issue also becomes absolutely devastating and poses an enormous threat to the environment. Unlike some humans who can sit in an air-conditioned room and stave off the effects (though human deaths have occurred) none of the coral surrounding Australia can escape this situation. Coral bleaching cannot be reversed - which is why action must be taken to attempt to stop it in its tracks.

Furthermore, the heat has led to increased bush fires. These fires have led to a massive loss vegetation in addition to the loss of wildlife. Steps can be taken to decrease the incidences of bushfires such as “controlled burning” but the degree of damage that has already been done is astounding.

I am curious about the extent to which Australia is capable of dealing with the repercussions of the heat in its entirety. I am curious even though Australia is a developed and wealthy nation due to the fact that these temperature highs are unprecedented and due to the irreversibility of the effects of coral bleaching. 

In terms of international cooperation - how can other nations be incentivized to care about Australia’s situation?

When is it acceptable to intervene in a developed nations affairs besides when applying the R2P principle? Would this situation be considered an R2P principle? If not, how would the situation need to degrade/what would need to occur to make it so? When, if ever, will R2P or something similar apply to environmental issues?
