NOAA Forecast: Great Barrier Reef Could Face Third Mass Bleaching Event in 4 Years
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.
The forecast shows a 60 percent chance that the entire reef will face extreme heat stress and coral bleaching between November 2018 and February 2019.
"This is really the first warning bells going off that we are heading for an extraordinarily warm summer and there's a very good chance that we'll lose parts of the reef that we didn't lose in the past couple of years," marine biologist and Global Change Institute at the University of Queensland Director Ove Hoegh-Guldberg told The Guardian. "These are not good predictions and this is a wake-up call."
The forecast further warns that the southern half of the reef has a 60 percent chance of experiencing a level two bleaching event, at which point coral death is likely, Australia's ABC reported.
The Great Barrier Reef suffered back-to-back bleaching events for the first time in 2016 and 2017, which killed 50 percent of the coral in shallow waters. If the reef suffers bleaching again in 2019, it will be the third time in four years, a frequency not predicted until the second half of the 21st century.

Bleaching is what happens when waters get so warm that corals expel the algae that live inside them, providing them with nutrients. If the water does not cool and the algae does not return in time, the coral starves.
However, NOAA scientists said there was still hope that forecasts could change.
"Lots of things, including major weather patterns, can change the probabilities over the next three months," Dr Mark Eakin, the head of NOAA's Coral Reef Watch, told ABC. "I wouldn't say dire yet, but it is concerning."
In 2016, for example Cyclone Winston cooled water temperatures enough to save the southern part of the reef from bleaching. Eakin noted that predictions for March, when coral bleaching is most likely to occur, are still unclear.
The Australian government said they took the forecast seriously.
"We acknowledge that climate change has an impact on the reef," Australia Environment Minister Melissa Price told The Guardian. "That's one of the reasons that Australia is working with other countries to tackle climate change through the Paris agreement, and we will deliver on the commitment to reduce emissions by 26-28 percent of 2005 levels by 2030."
However, the most recent report showed Australia's greenhouse gas emissions were rising, and Deputy Prime Minister Michael McCormack told SkyNews that the country would continue to use its coal reserves despite the IPCC report.
"How much more of the Great Barrier Reef has to die before the Federal Government acts on climate change,"AMCS spokesperson Imogen Zethoven asked in a press release. "While our Reef is in danger, our politicians continue to ignore the issue of climate change with no credible plan to reduce pollution."

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
"There was a lot of devastation throughout the state," Governor Mike Parson said at a Thursday morning press conference, as NPR reported. "We were very fortunate last night that we didn't have more injuries than what we had, and we didn't have more fatalities across the state. But three is too many."
