First Mammal Driven to Extinction by Human-Caused Climate Change Is Australian Rodent
A small Australian rat that lived on a 12 acre island in the Great Barrier Reef has become the first mammal to go extinct primarily because of human-caused climate change, the Australian Government confirmed Monday.
The Bramble Cay melomys was first declared extinct after a 2014 search on Bramble Cay, its native island in the Torres Strait, between Queensland, Australia and Papua New Guinea, according to a 2016 report by the University of Queensland and the Queensland government.
"The key factor responsible for the extirpation of this population was almost certainly ocean inundation of the low-lying cay, very likely on multiple occasions, during the last decade, causing dramatic habitat loss and perhaps also direct mortality of individuals," the report authors concluded. "Available information about sea-level rise and the increased frequency and intensity of weather events producing extreme high water levels and damaging storm surges in the Torres Strait region over this period point to human-induced climate change being the root cause of the loss of the Bramble Cay melomys."
Charles Darwin University professor John Woinarski, who has worked on the species, told the program Hack on Australia's ABC News that a 2008 recovery plan drafted for the species was never implemented.
"It's been known for a couple of decades it was in a pretty precarious position," he told Hack. "It suffered from living a long way away from anywhere else, and being a rat and being not particularly attractive. It didn't have much public advocacy for it."
Researchers believe there were several hundreds of the species on the island in the 1970s, but its numbers had fallen enough by the 1990s that it was listed as endangered, CNN reported.
An attempt to save the species with a captive breeding program took place too late. When researchers went to search for the melomys in 2015, they could not find a single rat left, according to Hack.
Greens Party Senator Janet Rice used the extinction to argue against Australia's reliance on fossil fuels.
"Bramble Cay melomys' extinction is an absolute tragedy," she said, according to CNN. "Labor and Liberal's addiction to coal is the death warrant for many of our other threatened animals."
If global greenhouse emissions are not reduced and global temperatures continue to increase, almost eight percent of species could go extinct, according to a 2015 University of Connecticut study. Australia, along with New Zealand and South America, is most at risk for losing its biodiversity due to climate change.
In the same press release that confirmed the melomys' extinction, Australia's Minister for the Environment Melissa Price also announced that the spectacled flying fox would now be listed as an endangered species, up from vulnerable, after a 2018 heat wave in Queensland cut its numbers by one third, according to The Guardian.
"The uplisting of the Spectacled Flying-fox reflects the Government's heightened concern for its future, given that the population has halved in the past decade, and was heavily impacted by a recent heat stress event in north Queensland," Price wrote.

For the past seven years, the Anishinaabe people have been facing the largest tar sands pipeline project in North America. We still are. In these dying moments of the fossil fuel industry, Water Protectors stand, prepared for yet another battle for the water, wild rice and future of all. We face Enbridge, the largest pipeline company in North America, and the third largest corporation in Canada. We face it unafraid and eyes wide open, for indeed we see the future.

We see the effects of the climate crisis all around us in hurricanes, droughts, wildfires, and rising sea levels, but our proximity to these things, and how deeply our lives are changed by them, are not the same for everyone. Frontline groups have been leading the fight for environmental and climate justice for centuries and understand the critical connections between the climate crisis and racial justice, economic justice, migrant justice, and gender justice. Our personal experiences with climate change are shaped by our experiences with race, gender, and class, as the climate crisis often intensifies these systems of oppression.

It was early in the morning last Thursday, and Jonathan Butler was standing on the Fred Hartman Bridge, helping 11 fellow Greenpeace activists rappel down and suspend themselves over the Houston Ship Channel. The protesters dangled in the air most of the day, shutting down a part of one of the country's largest ports for oil.

Climate change is by far the most serious crisis facing the world today. At stake is the future of civilization as we know it. Yet, both public awareness and government action lag way behind what's needed to avert a climate change catastrophe. In the interview below, Noam Chomsky and Robert Pollin discuss the challenges ahead and what needs to be done.
