Muddy water from historic flooding in Queensland, Australia is now flowing out of rivers into the sea, threatening even the outer shelves of the Great Barrier Reef some 60 kilometers (approximately 37.3 miles) from the coast, Australia's ABC News reported Friday.
Australian Institute of Marine Science (AIMS) water quality team leader Dr. Frederieke Kroon told ABC News that the runoff covered "an extraordinarily large area." Researchers said it is likely filled with nitrogen pollution and pesticides, and poses a risk to the health of a reef already damaged by back-to-back coral bleaching events in 2016 and 2017.

The climate is changing faster than many species can adapt, so scientists are trying to speed up evolution by fostering the spread of creatures who can take the heat. Think of it as natural selection with a little boost from humans—or, in some cases, robots.
The Great Barrier Reef has been hit hard by climate change. As waters warm, the higher ocean temperatures force the coral to expel the algae that lives inside of it, providing it with both its nutrients and its brilliant colors. If the water does not cool fast enough and the algae does not return, the coral dies.
The non-profit organization Great Barrier Reef Legacy and marine scientist Charlie Veron, a world expert on coral reefs, confirmed the diversity of the site, also known as the "Legacy Super Site" on the outer reef.
For any nature lover, one of the most sobering pieces of information from this month's Intergovernmental Panel on Climate Change (IPCC) report was that global warming of just two degrees Celsius above pre-industrial levels could kill off 99 percent of tropical coral reefs. And even if we act quickly and successfully limit warming to 1.5 degrees, 70 to 90 percent of these invaluable ecosystems will still be lost.
Now, an alarming forecast from the National Oceanic and Atmospheric Administration (NOAA) shows that process could begin as early as this Australian summer in one of the most iconic reefs of all: the Great Barrier Reef.
In a recent interview with SkyNews, deputy prime minister Michael McCormack said Australia will "absolutely" continue to use and exploit its coal reserves regardless of what the IPCC report says.
