Clear and Present Danger: Overwhelming Ourselves into Apathy

Head in Hands

After covering a AAAS session on science and the media in my blog post last week, I’d planned to focus on another titled “Adapting to a Clear and Present Danger: Climate Change and Ocean Ecosystems.” Two of the talks stood out for me: one on the potential impacts of ocean warming and acidification, and the other on coral reefs, and all the threats they face. I had all my notes, including quotes from the speakers and abstracts of their talks.  I’d even hunted down some of their earlier talks, and found cool graphics to accompany the post. Then, I sat down to write. But I couldn’t.

Why? Work’s been busy lately, especially since we’re trying to raise money for my primary project.  I’ve been neglecting my WIP (work in progress: a first person sci-fi novel), and wanted to work on that. And on top of all that was simple procrastination – or so I thought. I should have suspected that something was up. I like writing this blog, and don’t usually look for excuses not to. So why was I having so much trouble?

Some people would turn to soul-searching at this point. I turned to the web. And what do you know? It turns out that I’m not the only one who gets tired of reading (and writing) about bad news.

Wait, Don’t Tell Me

Climate change is real. So is ocean acidification, the demise of coral reefs and the destruction of rainforests. Not to mention (but I will anyway), the loss of dozens endangered species, overfishing, air pollution, ocean dumping and oil spills…

Have your eyes glazed over yet? Were you tempted to stop reading, to find something positive to check out for a change? Me too. It’s natural. No one can take a steady diet of misery – it just wears us down. Some psychologists believe that we have a finite capacity for worry and just can’t take it all in at once.* The kids are sick, I’m being downsized, the mortgage is due, there’s a tragedy in Japan – oh, and the climate is changing? Take a number. Sometime we go numb, tuning out what our brains just can’t handle.

That’s not a cop-out. Humans evolved to handle immediate threats like hungry predators, and modern-day stresses trigger same basic fight or flight response. But our bodies can’t stay on high alert all the time. After a while, the alarms stop ringing, and we go back to business as usual. Without doing anything.

If You Can’t Say Anything Nice…

That’s another problem – what can we do? The problems I’ve mentioned are so huge, is it even possible for one individual to make a difference?  Too often we scientists, reporters, bloggers and the like give folks the bad news without any ideas of what to do. Any reason for hope.  Is it any wonder people stop listening?

Some studies** suggest that people resist doing anything about climate change – and even deny that it is happening – because it contradicts their views of a “just world.” Surely, if God (or the Universe or humanity, etc) is good, things can’t be that bad. Or it will all work out in the end.  I have to admit that I fall into this camp sometimes.  I have to or else I could never keep working and writing about the issue of climate change.

So now what?

What does that mean for someone like me, who lives and breathes this stuff all the time, and tries to educate others about it, too? Some take-home lessons:

  • Stay away from the apocalyptic messages – they cause people to tune out.
  • Give people reason for hope, including things they can do and info about efforts underway to make a difference.
  • Share as much good news as possible.
  • Enjoy all the wonderful things about people, the environment, life – celebrate! Those are the REAL reasons we work so hard to save it all, right?

As I said, I do believe in a just world. I know we humans have the capacity to address the challenges of climate change in ways that will make the world a better place for having done so. And we can even have a good time while doing so.  To quote the incomparable Emma Goldman: “If I can’t dance, I don’t want to be part of your revolution.” Keep fighting the good fight – and dancing all the while.

Science and the Media, or How Science Advanced at AAAS 2011: Part I

Like This!

Most science conferences are like little in-group parties, where people who know each other’s work intimately get together to discuss their latest results, and query each other about what to do next. Don’t get me wrong – I love them. You meet interesting people, learn A LOT, and come home with new ideas, and great T-shirts or shoulder bags.  Since I am a generalist by nature, I’ve attending lots of different kinds of conferences: the Geological Society of America, the American Physics Society, the European Geophysical Union, the Estuarine Research Federation, and the Coastal Society, to name a few.

The AAAS Annual Meeting, which I attended for the first time this year, was completely different. The raison d’etre of “triple-A-S” is right there in its name: the American Association for the Advancement of Science.  I didn’t really get what that meant until now. Instead of technical talks, where experts talk to their peers about the incremental advances in their area of science, this meeting was all about the big picture. Panels of speakers addressed different aspects of a single topic, speaking broadly about what was known, where the gaps and questions were, and what they’d like to see happen next. Scientists from different fields sat in on each others’ sessions, offering all sorts of interesting and cross-disciplinary questions and comments. The meeting wasn’t only for and about scientists, either. A number of panels focused on the communication of science, and the relevant of science to society. It was amazing. There was also a two-day Family Science Fair, which my son and nephews loved.  I picked up all sorts of great science swag, including posters, bumper stickers, calendars and buttons, which I will start giving away next week.

Over the next few weeks I will report on some of these great sessions in depth, including:

  • Science Without Borders and Media Unbounded: What Comes Next
  • Adapting to a Clear and Present Danger: Climate Change and Ocean Ecosystems (I may have to dedicate two blog posts to this session, which included fabulous talks on coral reefs and ocean acidification by James Brady of MBARI, and Nancy Knowlton of the Smithsonian).
  • 2050: Will There Be Fish in the Ocean?
  • Comparing National Responses to Climate Change: Networks of Debate and Contention (focusing on the differences between how climate change is viewed in the US and India – the two countries where I do my climate change work).

First up: science and the media.

Media Unbounded

“Science Without Borders and Media Unbounded: What Comes Next,” focused on the impact of the Internet on media, and featured a panel of journalists who focus on science and environmental reporting: Tom Rosenstiel, Director of the Pew Research Center’s Project for Excellence in Journalism, Elizabeth Shogren, reporter for National Public Radio (NPR), and Seth Borenstein, reporter for the Associated Press (AP). Kerry Emanuel, a researcher in the Program of Atmospheres, Oceans, and Climate at the Massachusetts Institute of Technology (MIT) responded to their presentations.

Tom Rosenstiel gave a fascinating overview. The world of media is both shrinking and expanding. The editorial aspects are expanding: there is more commentary and discussion than ever. The reportorial component – where people actually go out to discover and confirm things – is shrinking. As more people get their news online, the print newspaper is fading, but publishers are not: most people still get their news from a handful of trusted sources like the New York Times, Washington Post, and others. However, since they’re not paying for it, newspaper budgets and pressrooms are shrinking. There are more readers, but fewer reporters.  This has led to the loss of specialized beats, like the environment, particularly in local papers. This also means that reporters don’t get into stories in-depth, instead sticking to breaking the news. There are fewer interviews, less follow-up. What has this done to our public square? Perhaps the world we’re exposed to is smaller, our common knowledge pool is shrinking. As readers (and listeners) we’re spending less time learning about the larger world and more time on our particular interests.

Elizabeth Shogren spoke about how the Internet has made her job easier and more interesting. She can spend more time getting the interesting stories (because that is still a priority at NPR), and can do more with them. In addition to a radio report, she can – and is expected – to present a whole multi-media story, complete with online images, and videos. She can include information that didn’t make it into the recording, and give listeners resources for more information. She noted that the Internet makes information more accessible, and has the potential to make governing more transparent. Now, even if she can’t be on Capitol Hill at 1:00 AM to follow the debate on an important bill, she can get all the information – videos and transcripts – online. In theory, this takes away one of the tactics that lawmakers have used to ‘hide’ debates they didn’t want the public to pay attention to – but only if people take advantage of the information that is out there.

The Differences Between Researchers and Reporters

Seth Borenstein spoke about the incredible access that the Internet gives him to scientific data, allowing him to dig through the databases and reports about climate change that researchers routinely put up on their websites or on government and other shared sites. (I took note of these, and you can expect to here more about specific findings and studies in future posts). He used this access to disprove a recent claim of climate change deniers:  that January’s temperature were colder than usual and therefore ‘proved’ that global warming wasn’t happening. Instead, he discovered that for the past 311 months – every month since February 1985 – temperatures have been warmer than the long-term average for that month. He followed with a statement that had all the scientists in the room groaning in disbelief. He said that IF January 2011 had been warmer, THAT would have been a story that his editor would have wanted to hear, but the fact that every month for nearly 26 YEARS had been warmer was not a story!  The facts weren’t interesting – only the controversy.  And this from a reporter who truly gets, and likes reporting on science and climate change.  Is it any wonder that so many scientists are reluctant to speak to the media?

Kerry Emanuel took up this issue in his comments. He opened with a quote from Oscar Wilde to express how many scientists see the media: “In old days men had the rack. Now they have the press.” He noted the dichotomy in the modern media (and one that journalists rarely acknowledge): the media as the fourth estate, with high ideals vs. media as a business. Scientists sometimes get tripped up by this tension. They often assume (perhaps naively) that they and the reporter have the same objective: to get to the truth. Even if languages are different, the end result is usually good. However, that is not always the case – sometimes the journalist just wants to sell the story. Sometimes journalists bend the story into something they think will sell. This makes scientists wary – they have to determine where the journalist coming from. (Shogren’s response was that scientists need to do their homework, and learn more about the journalist who is approaching them. If they don’t like the kind of things he or she writes, the researcher doesn’t have to talk).

Global Warming Deniers: Who’s To Blame?

Shogren complained that she though the global warming debate was settled, but was frustrated to hear it coming up again. Disturbingly, she blamed it on the scientists, saying that they (we) hadn’t done a good enough job explaining it to the public!  There was an immediate outcry: the science has gotten stronger, but the media keeps allowing the debate to be re-opened. She said that if there was controversy, they had to report it. Researchers said: there’s no controversy in the facts, but the media keeps giving the stage to fringe groups with vested interests in undermining the facts. Very interesting.

During the Q & A, I asked all the members of the panel how Twitter and blogs had changed the way they do their reporting, if at all. Surprisingly, there were few comments. (Perhaps they thought those venues were about information, not ‘news’).  Rosenstiel said that the Internet gave any expert access to an audience (unspoken, but implied was the critique that it also gives access to the clueless, as well).

Coming up next: Climate change and Ocean Ecosystems.

Brave Blue Word’s End of the Year Ocean Round-up 2010

2010 was a hard year for the oceans. The biggest disaster was, of course, the BP Deepwater Horizon oil spill, which raged on for a mind-boggling, stomach-curdling three months. While BP and the Feds are alternating between pointing fingers, and patting themselves on the back for saving the Gulf, the true impacts of the disaster will be making themselves known for a generation or more.

However, not all the news was bad news. 2010 also saw some major victories and discoveries that furthered our understanding and protection of the Big Blue:

  • Census of Marine Life: In 2010, more than 2,700 researchers from 81 countries completed a decade-long survey of the world’s oceans. More than 540 expeditions culminated in the discovery of thousands of new species. Researchers found life everywhere they looked, from the coldest to the hottest waters, from the water’s surface to depths with pressures high enough to crush steel. Ocean geek that I am, I get positively giddy thinking about the wealth of scientific information and journal articles available on their website. I’ve blogged about this amazing effort here, and here, and definitely will again.
  • Marine Protected Areas (MPAs). The California Fish and Game Commission voted to establish 36 MPAs along the state’s southern coast, from the Point Conception to the Mexican border. More than 20% of U.S. lands are protected in national parks and the like, but less than 1% of the ocean has any comparable protections. A recent study conducted by researchers at Oregon State University (Christie et al., 2010) found that fish larvae from MPAs can help rebuild overfished populations more than 100 miles away.
  • Shark Conservation Act: Shark finning is the barbaric practice of cutting off the fins of a shark for the Asian delicacy of shark fin soup. The shark is often tossed back in the water still alive to bleed to death. “Of the 307 shark species assessed by the International Union for the Conservation of Nature, 64 are listed as vulnerable, endangered or critically endangered due to shark finning.”*  Back in April, Hawaii banned shark finning in state waters. Early this month, Congress followed up with a ban on new shark finning in all U.S. waters. (Last year, the EU closed a loophole in their finning ban to effectively stop the practice in European waters).

Grey reef shark (Carcharhinus amblyrhynchos)

My round-up wouldn’t be complete without mentioning a few of my favorite ocean organizations, which did fabulous work in 2010. Check them out and support their efforts in 2011 and beyond. I’ve put my money where my mouth and keyboard are to support each of these amazing groups.

  • Ocean Champions is the only political voice for the oceans. They work on politics, not only policy, pushing ocean legislation, and supporting candidates from both parties who support the ocean. They’re incredibly savvy about the workings of Capitol Hill, and know how to get things done. Fed up with gridlock? Support a group that works hard to ensure that ocean issues are heard in our nation’s capital.
  • Sylvia Earle Alliance. I can describe Sylvia Earle in one word: hero. But why stop there? How about awesome, incredible, cool, fun, adventurous, dedicated, passionate, and smart. I had the pleasure of meeting her back in 1997, and she lived up to everyone of those words and more. She was recently named Treehugger’s Person of the Year. Check out Sylvia’s awesome TED speech here.

  • Wallace J Nichols. Wallace is a one-man ocean revolution. He’s a researcher, educator, and activist, working in a dozen different ways to communicate his love, passion, and concern for the seas to people all over the world.  His motto is to “live like you love the oceans,” and there’s no doubt that he’s walking the walk in more ways than you can imagine. 100 Blue Angels is a campaign he’s recently launched to support his work. You can check out his 2010 Top Ten list here.

Next month I’ll blog about some of the legislative battles on the horizon for 2011.  So stay tuned for more Brave Blue Words, and have a Happy New Year!

Coming soon to a beach near you – the jellyfish blob

Giant Nomura, Sea of Japan. These jellies can grow to 450 lbs. and be the size of a refrigerator.

Woman Screaming

The meek shall inherit the Earth – at least the wet parts of it. The lowly jiggly jellyfish, those simple critters that are mostly water and stomach, may be the big winners in the high-stakes gamble we’re playing in the oceans on a global scale.

Beautiful and bizarre, jellyfish are on the rise in many places. These otherworldly gelatinous floaters are appearing in greater numbers and causing an increasing array of problems in coastal waters favored by people for swimming, fishing, and working.

They can be physically harmful, stinging and sometimes killing swimmers unfortunate enough to get close. They clog up fisherman’s nets (or it that there’s nothing else left to catch?), and the intake pipes of power plants. They jam up harbors, and slaughter penned salmon by the thousands. Their stinging tentacles can ruin a catch by tainting or killing the fish caught up with them in nets.

Some of the biggest threats to overall marine biodiversity benefit these creatures. Warmer waters seem to favor some species, enabling them to expand their ranges, appear earlier in the year and increase overall numbers. Nutrient pollution – the runoff of enormous amounts of fertilizer from fields and lawns into ocean waters – stimulates phytoplankton blooms that in turn feed huge swarms of jellyfish. Overfishing removes many of their predators, and they compete with the fish we like to eat for prey, often preying on fish larvae as well.

What is a jellyfish? Of course, they’re not fish in any sense of the word. The stinging jellies, also known as medusa, are free-swimming members of the phylum Cnidaria (pronounced without the “c”). This phylum also includes corals and sea anenomes, all of which capture prey with stinging cells called nematocysts. Comb jellies are members of the phylum Ctenophore. These non-stinging creatures use rows of tiny hairs called cilia to move about. Both types of jellies are on the rise.

Jellies are found everywhere – from the tropics to the poles and the surface to the deepest reaches of the sea. More than fifty new species of jellies were discovered by the Census of Marine Life in the cold salty depths of the Arctic sea.

Jellyfish Lake, Palau.

They’re coming to take over a coastline near you! Or are they? Not all researchers agree with the dire scenarios of “Jellies Gone Wild!” Steven Haddock who studies gelatinous phytoplankton at the Monterey Bay Research Institute (MBARI) jellies capture people’s imaginations – and fear – because of their resemblance to the stuff of B-movies. (This is the second post in a row where I’ve managed to invoke B-movies!) However, as creatures that need to eat, and which are themselves eaten, jellies are a natural part of the ecosystem. But the same can be said for many invasives, no?

Part of the problem is that there are few reliable estimates of jellies before the 1990s. That’s when people started taking notice of large blooms near where they live, fish, and swim. “Undoubtedly there are localized areas where blooms have increased. … On a global scale, we don’t know enough about jellyfish populations, their biology, their distribution, to make a judgment,” says Rob Condon, one of the lead investigators for the National Center for Ecological Analysis and Synthesis jellyfish working group.

This past summer saw a jellyfish invasion in Spain. In Japan’s waters, blooms of jellies the size of refrigerators, weighing up to 450 pounds are now an annual occurrence. Last year, a netful of jellies capsized a ten-ton trawler off the coast when fisherman tried to pull the nets up. In 2007, 100,000 penned salmon were killed by a bloom of jellies off Ireland. Off the coast of Sweden, American comb jellies and the stinging larvae of sea anemones have become late summer pests. Local officials have placed nets around some Queensland beaches to fend off common box jellyfish and the deadly irukandji. One of the few studies to look at long-term trends confirmed an increase in size and density of blooms of the mauve stinger, Pelagia noctiluca, in the Northeast Atlantic and Mediterranean over the past fifty years.

Misunderstood marvel or toxic threat? Ever been stung by a jelly? Swam in a swarm? Stumbled upon a beached Portuguese man-o-war? (Don’t touch! The stinging cells remain dangerous and can be fired even after the creature is dead). Leave your comments below!

Riches Beyond Your Wildest Dreams: More on the Census of Marine life

I had planned to write a cool post about tides today, followed by one or more about tide pools, the intertidal zone, and other (possibly) related topics.  I’d even thought of a clever title (which I won’t tell you in case you disagree with my wit).  But then, as often happens, I was distracted by something else, something pretty, shiny, new, and totally cool. My copy of the “World Ocean Census” arrived in the mail.*

The World Ocean Census is one of the popular science books that catalogue the findings of the Census of Marine Life, that treasure trove of riches I told you about in an earlier post, and promised to write about again (and again, and again). As I started to peruse this beautiful volume, it became harder and harder to pick a topic.

Should I focus on the sooty shearwater, found to have the greatest migratory route of any organism? This little bird clocks 40,000 miles a year in its annual migration between New Zealand and the northern Pacific. No, that’s not a typo, it’s forty THOUSAND miles a year, up to 550 a day, with dives to 200 feet to hunt its usual prey of fish, squid, and krill.

A sooty shearwater taking a much-deserved rest.

Perhaps I should take a look at seamounts, underwater mountains or hills rising 3,000 feet or more from the ocean floor that are often hotspots of biodiversity in the vast ocean? Over 40% of the species found on any given seamount are unique to that particular spot. Over the course of the census, thousands of new species were discovered on seamounts – over 600 on 5 seamounts alone! How did this incredible richness arise? Does the isolation of one seamount from another encourage the development of new species? Are seamounts refuges for species whose ranges have shrunk? Only about 400 seamounts have been sampled to date, and only 100 in any detail, so we have yet to answer these questions, but the census has brought us that much closer.

Or maybe I should examine the activities that threaten these amazing species and ecosystems. “Overfishing and pollution were identified as the main threats to biodiversity across all regions, followed by alien species, altered temperature, acidification, and hypoxia, although their relative importance varied among regions.” These threats are real, and accelerating. So science must do the same. “There is a need to accelerate the discovery of marine biodiversity, since much of it may be lost without even being known.”

At the very least, let’s accelerate our discovery of the known, shall we? To begin with, I’ll let you in on a secret, something amazing that I have discovered: as a result of the Census of Marine Life, hundreds of articles have been published in scientific journals, much of them are in open access journals such as the Public Library of Science (PLOS One). So expect to see more about the amazing, spectacular, and ever extraordinary (is that enough, you think?) creatures that live in the world’s ocean in the weeks to come.

Crazy about octopus? Mad about sharks? Can’t get enough about bryozoans? (Hey, it’s possible – assuming you know what a bryozoan is…). Let me know, and perhaps that’s what will get pulled out of the Census magic hat next time!

Until then – follow daniellemeitiv on Twitter – and you can “like” this blog on Facebook, too! Much appreciated.

Fishing For Answers: Connecting Ocean and Human Health

Walking home from an early appointment this morning, I considered what to write about for today’s blog post. An article about marine ecosystems and fisheries caught my eye yesterday. While intrigued, I was also reluctant – fisheries management is one subject that both interests and frustrates the hell out of me. I took one class on fisheries biology in graduate school. After seeing how politically charged fisheries management can be, and how often decisions are made with little regard for science, I swore I would never work in that field. (My vow backfired, of course and I spent 2.5 years working on fisheries-related issues for the Environmental Defense Fund* – in New England of all places, the most politically charged fishery of them all!) When I spotted a second fisheries article this morning – this one in the Washington Post about seafood choices that are “good for the oceans, good for you,” I knew I had to make my peace with the issue.

The first article reports on a comparative study of North Atlantic and North Pacific ecosystems conducted by team of American scientists from the National Oceanic and Atmospheric Administration (NOAA – I’ve worked for them, too, but not on fisheries, thank God) and Norwegian scientists. The study, Marine Ecosystems of Norway and the US (MENU) is “the first attempt to provide a comprehensive, coordinated and integrated view of a wide range marine ecosystems.”

MENU results revealed that deeper ocean boundary systems, like those off Alaska or in the eastern North Atlantic, off Europe, are more strongly influenced by bottom-up mechanisms, known as forcing. The shallower western boundary systems found on continental shelves, like Georges Bank off New England are more strongly influenced by top-down processes, like fishing.

Could this difference make these latter ecosystems less resilient, more susceptible to collapse from overfishing? Perhaps this would explain why eastern fisheries, like Atlantic cod and other “groundfish”**, are doing so poorly compared to western fisheries, like salmon and halibut. Perhaps as a result of overfishing, fisheries landings in both types of ecosystems have shifted from fish to invertebrates, and bottom-dwellers to pelagic species.

Human activity, especially fishing, pollution, and climate change are having dramatic, even catastrophic impacts on marine ecosystems. One response might be to stop eating fish altogether. On the other hand, hardly a day goes by without a new study trumpeting the heart-healthy benefits of adding fish to our diets. So what can we do?

Well, my old friends at EDF have teamed up with the Monterey Bay Aquarium to develop the ‘super green’ list of fish that are good for the oceans AND good for you. The “Best of the Best” are those fish that high in omega-3′s, low in contaminants, and caught in a sustainable manner. “Other Healthy Best Choices,” while strangely titled, are those that are lower in omega-3 but still good choices.

Lest you underestimate the importance of omega-3′s in your diet Dariush Mozaffarian, of Harvard Medical School who helped with the rankings, noted that eating an average of one serving of salmon a week provides enough omega-3 to reduce heart disease risk by 36%. (Question: If the subjects he studied had typical American diets that salmon meal probably replaced a high-fat meat dish – did that also help to lower their rate heart disease?)

The Super Green list is not yet available in a handy wallet-sized pocket guide like previous efforts but will likely be so soon. To read more , click here.

More info about the MENU study is available through NOAA Northeast Fisheries Science Center, here.

* I worked for EDF during the brief period when they dropped the “f” and became Environmental Defense. There’s a ridiculous rumor about why they changed it back, but I won’t go into it here… :-)

** Groundfish is a bizarre term that is used in fisheries management, in spite of the fact that it has no ecological relevance. It refers to all fish that live somewhat near near the seafloor and can be caught using huge bottom-dragging nets. It is as if we referred to deer, racoon, fox, etc. as “landanimals” and hunted them together using bulldozers…
