Coral reefs "gone in sixty seconds"

Time's up

Well, sixty seconds in a geological context – actually by 2050. Coral reefs have been on the planet for aeons, but one extra molecule of CO2 out of every ten thousand in the atmosphere caused by your SUV is enough to finish them off in less than 40 years:

The world’s coral reefs could be wiped out by 2050 unless urgent action is taken to stop threats posed to the “rainforests of the sea” by everything from overfishing to climate change, a report warned Wednesday.

Warmer seas caused by global warming; ocean acidification blamed on carbon dioxide pollution; shipping, overfishing, coastal development and agricultural runoff all pose a threat to coral reefs, which hundreds of millions of people depend on for a living, says the report.

“Threats on land, along the coast and in the water are converging in a perfect storm of threats to reefs,” Jane Lubchenco, administrator of the National Oceanic and Atmospheric Administration (NOAA), said at a news conference in Washington to launch the “Reefs at Risk Revisited” report.

According to the report, which follows on from an earlier study on the health of the world’s coral reefs, more than 90 percent of reefs will be threatened by 2030 and nearly all reefs will be at risk by 2050 unless action is taken now to reduce the threats.

“Local pressures” on reefs, including overfishing, coastal development and pollution, pose the most immediate and direct threats to the world’s reefs, threatening more than 60 percent of the colorful sea ecosystems.

The impacts of climate change — a “global threat” to reefs — is compounding the local pressures.

“Warming seas have already caused widespread damage to reefs, with high temperatures driving a stress response called coral bleaching, where corals lose their colorful symbiotic algae, exposing their white skeletons,” the report says. (source)

  1. I guess these Japanese corals didn’t get the memo…

    “A new study of reefs around Japan reveals that a handful of coral species have migrated from the balmy subtropics to temperate climate zones over the last 80 years. The study is the first to track coral reefs for such a long time and over several latitude lines, a Japanese team reports in an upcoming Geophysical Research Letters”

  2. If you only read the ABC this report that claims “Coral reefs could be gone by 2050″ it may have sent the shivers down your spine. Here’s some research ABC’s activists are unlikely to report that provides a more realistic outcome based on a little thing called evidence…

    Of interest is sthat while there has been some northward movement the southern end has seen no change since 1930.

    It’s stunning that these moonbats come out daily with thermageddon pronouncements that are simply bald-faced lies, which can be refuted with a few mouse clicks. Do they think they are the only ones with search capabilities?

  4. I think you are dead right to question the warming influence which as thinking people (like us) know is probably bunkum. However, the article possibly does have a valid point about the local effects: fishing, agricultural run off etc.

    Gone in “60 seconds” though? I think not.

    Terrific blog! Never give in.

    The minute portion of Julia Gillard’s remaining credibility now – Gone in (less than) 60 Seconds on the 24th February 2011:-

    “I’m determined to price carbon,” Ms Gillard told a joint press conference with Greens leader Bob Brown and Senator Christine Milne well as independent MPs Rob Oakeshott and Tony Windsor.

    “History teaches us that the countries and the economies who prosper at times of historic change are those who get in and shape and manage the changes. The time is right and the time is now.

    Julia Gillard August 2010:-

    “There will be no carbon tax under the government I lead.”

    There is not doubt now that the real Julia is just……A LIAR…

    You know what… if ever the day comes when alarmists are brought to account in a court of law, and made to produce real empirical evidence (based on the scientific method) to support their claims, their consensus pseudo-science will be left in tatters… and their claims deemed fraudulent!
