Even in Deepwater Canyons, America's Corals At Risk

August 31, 2014 by NRDC Switchboard

Corals and Environmental Risk

At the beach this summer, gazing out over the waves from the shoreline, it's hard to imagine the underwater world that lies just below the blue expanse: Partly because it’s so other-worldy, and partly because we just don't know very much about it.[read more]

Is the 2 degree target likely to save most coral reefs?

September 21, 2012 by Simon Donner

The new paper in Nature Climate Change by Katja Frieler, a number of other colleagues and I warns that limiting global warming to 2 deg C Celsius, the threshold long-discussed at the policy level and now enshrined in the Cancun Accord, is unlikely to be enough to spare most coral reefs from climate change. The paper might look like the...[read more]

A Prelude to Rio: Mexico Takes a Stand to Protect Irreplaceable Coral Reef

June 18, 2012 by Peter Lehner

NRDC has been calling for the Rio+20 Earth Summit to be a different type of international meeting – one where our world leaders act, and not just talk. On Friday, Mexican president Calderón set the stage for Rio with the rejection of a controversial and destructive tourism development project on the Baja California coast. This is...[read more]

Climate change and the Caribbean coral bleaching, again

October 25, 2010 by Simon Donner

There's an upswing of skepticism about climate change of late, thanks in part to the crazy season in the US (and I'm not talking about the baseball playoffs, although they have been pretty surprising too). While the pundits argue, the climate keeps on moving. When I give talks about climate change and coral reefs, I almost always use...[read more]

The second "global" coral bleaching event

September 20, 2010 by Simon Donner

The NY Times has an article on the observations of coral bleaching across the planet over the past 12 months, an subject I've raised here in the past few months. The NY Times article calls the concurrence of events "only the second known global bleaching of coral reefs". Though the characterization is awkward and not terribly accurate,...[read more]

McKibben on the invisible oil slick

May 3, 2010 by Lou Grinzo

Bill McKibben nails it in, Oil Slick You Can’t See Threatens the Entire Ocean: If you think that slick of oil spreading across the Gulf of Mexico is a nasty sight … well, it is. And so we’ll probably do something about it. Within hours of the crude reaching the coast, an aide to President Barack Obama said new offshore drilling would...[read more]

The headline "World's coral reefs could disintegrate by 2100" comes out of field and modeling work presented by Jacob Silverman about the balance of calcium carbonate production through coral calcification of corals...[read more]

More on the coral reef crisis

October 5, 2009 by Simon Donner

A new viewpoint article by Charlie Veron and a number of top coral reef scientists summarizing the near-term threats of rising CO2 on the world's coral reefs appears in the latest issue of Marine Pollution Bulletin. The take-home message of the article is right there in the title: "Coral reef crisis: The critical importance of <350...[read more]

Important viewing on corals

September 28, 2009 by Simon Donner

It is worth taking the time to watch Charlie Veron's talk "Is the Great Barrier Reef on Death Row?", presented at the British Royal society earlier in the summer. A version of this talk inspired Chris Turner's terrific article in this month's issue of the Walrus.Veron literally wrote the book about corals. His three volume tome Corals of...[read more]

El Nino and the likelihood of mass coral bleaching

July 23, 2009 by Simon Donner

The seasonal forecasting system recently developed by NOAA Coral Reef Watch suggests that coral reefs in the Caribbean and in part of the central equatorial Pacific (the Line Islands, including Kiritimati or "Christmas Island") are at risk of coral bleaching in the coming months due to warm ocean temperatures. The forecast is due to the...[read more]

Coping with Commitment: New study on the challenge facing coral reefs

June 2, 2009 by Simon Donner

Maribo's back from a long hiatus, in which the host was overseas collecting data, samples and I fear some sort of parasite. Just in time, as a new study of mine on climate change and coral reefs just appeared in PLOS-One today (link - no subscription required).As many of the regular readers have heard before, one of the biggest...[read more]

Coral reefs: The fierce urgency of now

July 15, 2008 by Simon Donner

Maribo's been on hiatus while I was preparing for and attending the 11th International Coral Reef Symposium in Fort Lauderdale. The conference is held only every four years; if you do any coral reef research, IRCS is not to be missed.One of the overarching messages of the conference, featured in the plenaries, countless individual...[read more]
