Scientist Tim Gordon studies how rising temperatures are damaging corals in Australia's Great Barrier Reef, where intense cyclones and warm waters have caused extensive damage in recent years. What he sees brings him to tears.

The federal agency that manages the Great Barrier Reef issued an unprecedented statement that broke ranks with Australia's conservative government and called for urgent action to reduce greenhouse gas emissions, according to the Guardian.

A changing climate is altering oceans in major ways and coral reefs around the planet may not be able to adapt to survive.

A fire broke out in Paris' iconic Notre Dame cathedral Monday evening. It burned for almost five hours, destroying two-thirds of the roof and causing its spire to collapse.

The church, which has stood in Paris since the 1200s, has come to embody "the permanence of a nation," Henri Astier wrote for BBC News. It was last seriously damaged during the French Revolution and survived both World Wars.

The Great Barrier Reef faces yet "another nail in the coffin," Dr. Simon Boxall from the National Oceanography Centre Southampton told BBC News Friday.

That is because the Great Barrier Reef Marine Park Authority (GBRMPA) has approved plans to dump one million tonnes (approximately 1.1 million U.S. tons) of sludge into the World Heritage Site. The decision comes in the same month that runoff from flooding in Queensland, Australia threatened to smother part of the reef and two years after the unique ecosystem was weakened by back-to-back coral bleaching events caused by climate change.

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.
