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 Florida Keys is home to the third largest living coral barrier reef system in the world. The ecosystem is a habitat for fish species and other marine life and also serves as economically important touristic and recreational spot.

The year 2018 was the hottest year for the planet's oceans ever since record-keeping began in 1958, according to a worrisome new study from international scientists.
The findings, published Wednesday in the journal Advances in Atmospheric Sciences, noted that the five warmest years for our oceans were the last five years—2018, 2017, 2015, 2016 and 2014 (in order of decreasing ocean heat content).
'Last Chance': Warming Could Be Limited to 1.5°C With Immediate Phaseout of Fossil Fuel Infrastructure, Researchers Say
It is still possible to limit global warming to 1.5 degrees Celsius above pre-industrial levels, a study published Tuesday in Nature Communications found, as long as we act immediately to phase out fossil fuels.
The study used a climate model to determine what would happen if, beginning at the end of 2018, all existing fossil fuel infrastructure—from industrial equipment to cars to planes to ships to power plants—was replaced with renewable alternatives at the end of its design lifetime. The researchers found there would be a 64 percent chance of limiting warming to 1.5 degrees, in line with the most ambitious goal of the Paris agreement.

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.
