Highlights of the Week – March is a record-breaker; West coast oysters impacted by acidification
Have a great weekend-
Highlight of the Week…. March is a record-breaker; west coast oysters and acidification
(Credit: NOAA) Over 15,000 Records Broken as March 2012 Becomes Warmest on Record
NOAA: U.S. records warmest March; more than 15,000 warm temperature records broken First quarter of 2012 also warmest on record; early March tornado outbreak is year’s first “billion dollar disaster”
According to NOAA scientists, record and near-record breaking temperatures dominated the eastern two-thirds of the nation and contributed to the warmest March on record for the contiguous United States, a record that dates back to 1895. The average temperature of 51.1 degrees F was 8.6 degrees above the 20th century average for March and 0.5 degrees F warmer than the previous warmest March in 1910. Of the more than 1,400 months (or more than 116 years) that have passed since the U.S. climate record began, only one month, January 2006, has seen a larger departure from its average temperature than March 2012.

ABSTRACT: We report results from an oyster hatchery on the Oregon coast, where intake waters experienced variable carbonate chemistry (aragonite saturation state < 0.8 to > 3.2; pH < 7.6 to > 8.2) in the early summer of 2009. Both larval production and midstage growth (∼ 120 to ∼ 150 µm) of the oyster Crassostrea gigas were significantly negatively correlated with the aragonite saturation state of waters in which larval oysters were spawned and reared for the first 48 h of life.The effects of the initial spawning conditions did not have a significant effect on early-stage growth (growth from D-hinge stage to ∼120 µm), suggesting a delayed effect of water chemistry on larval development.

While migrating birds are believed to use the earth’s magnetic field to navigate, new research has again baffled scientists as to how they do it. According to an article published in Nature on Wednesday, iron-filled beak cells previously thought to be the centre of the magnetic sense in birds are made up of normal protein-bound iron deposits which are not magnetoreceptive. Scientists who took part in the international study said the finding had taken them back to square one. “The mystery of how animals detect magnetic fields has just got more mysterious,” said David Keays, an Australian who now works at the Institute of Molecular Pathology in Vienna, Austria. ….

A cut-off of water supplies to a key Klamath Basin national wildlife refuge contributed to the deaths of 10,000 or more birds this year, the most in a decade, the refuge’s manager says. The Lower Klamath refuge in southern Oregon and northern California is a crucial stop for birds migrating along the Pacific Flyway. The refuge and five other refuges in the basin are also last in line for water, behind farmers and endangered fish, in one of the most water-short — and politically fraught — regions in the West. Ron Cole, project leader for the Klamath Basin National Wildlife Refuge Complex, estimates 10,000 to 15,000 birds have died from avian cholera this year. From December to mid-March, the U.S. Bureau of Reclamation cut off water supplies to the 46,900-acre Lower Klamath refuge, citing light snowfall and projections of dismal inflows to Upper Klamath Lake, which stores water for farmers and three fish species listed under the Endangered Species Act. …

Sunday, April 8, 2012 (SF Chronicle) Kelp off California was contaminated with short-lived radioisotopes a month after Japan’s Fukushima Dai-ichi nuclear plant accident, a sign that the spilled radiation reached the state’s coastline, according to a new scientific study. Scientists from CSU Long Beach tested giant kelp collected off Orange County, Santa Cruz and other locations after the March 2011 accident and detected radioactive iodine, which was released from the damaged nuclear reactor. The largest concentration was about 250 times higher than levels found in kelp before the accident….The radioactivity had no known effects on the giant kelp, or on fish and other marine life, and it was undetectable a month later. Iodine 131 “has an eight-day half-life, so it’s pretty much all gone,” Manley said. “But this shows what happens half a world away does effect what happens here. I don’t think these levels are harmful, but it’s better if we don’t have it at all.” Spread in large, dense, brown forests across the ocean off California, giant kelp is the largest of all algae and grows faster than virtually any other life on Earth. It accumulates iodine, making it a useful way to check how far radioactive material spreads.

Research shows for the first time that indigenous people, living in the savannas around the Amazonian forest, farmed without using fire. Instead early inhabitants practiced ‘raised-field’ farming, which involved constructing small agricultural mounds with wooden tools. These raised fields provided better drainage, soil aeration and moisture retention: ideal for an environment that experiences both drought and flooding. … > full story

Evolution at sea: Long-term experiments indicate phytoplankton can adapt to ocean acidification (April 8, 2012) — Fossil fuel derived carbon dioxide has a serious impact on global climate but also a disturbing effect on the oceans, know as the other CO2 problem. When CO2 dissolves in seawater it forms carbonic acid and results in a drop in pH, the oceans acidify. A wealth of short-term experiments has shown that calcifying organisms, such as corals, clams and snails, but also micron size phytoplankton are affected by ocean acidification. The potential for organisms to cope with acidified oceanic conditions via evolutionary adaptations has so far been unresolved. Scientists have now for the first demonstrated the potential of the unicellular algae Emiliania huxleyi to adapt to changing pH conditions and thereby at least partly to mitigate negative effects of ocean acidification. … > full story

Impact of warming climate doesn’t always translate to streamflow (April 6, 2012) — An analysis of 35 headwater basins in the United States and Canada found that the impact of warmer air temperatures on streamflow rates was less than expected in many locations, suggesting that some ecosystems may be resilient to certain aspects of climate change. … The study was just published in a special issue of the journal BioScience, in which the Long-Term Ecological Research (LTER) network of 26 sites around the country funded by the National Science Foundation is featured. Lead author Julia Jones, an Oregon State University geoscientist, said that air temperatures increased significantly at 17 of the 19 sites that had 20- to 60-year climate records, but streamflow changes correlated with temperature changes in only seven of those study sites. In fact, water flow decreased only at sites with winter snow and ice, and there was less impact in warmer, more arid ecosystems. “It appears that ecosystems may have some capacity for resilience and adapt to changing conditions,” said Jones, a professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences. “Various ecosystem processes may contribute to that resilience. In Pacific Northwest forests, for example, one hypothesis is that trees control the stomatal openings on their leaves and adjust their water use in response to the amount of water in the soil. “So when presented with warmer and drier conditions, trees in the Pacific Northwest appear to use less water and therefore the impact on streamflow is reduced,” she added. “In other parts of the country, forest regrowth after past logging and hurricanes thus far has a more definitive signal in streamflow reduction than have warming temperatures.”…> full story

Warmer and wetter weather is good for tree diseases, which is bad news for trees
Susan Frankel/USDA-Forest Service
Climate change is likely to wreak havoc on California’s forests. Extreme weather, wildfires and insect outbreaks will all take a toll. Add to those another looming threat: disease. Forest diseases like Sudden Oak Death, which has infected trees in 14 counties in the state, stand to benefit from the effects of climate change, to the detriment, obviously, of the trees.
Trees are big and long-lived. Tree pathogens, mostly fungi and bacteria, are the opposite. They’re mobile, able to blow around on the wind. And they reproduce and evolve rapidly. That’s the crux of the problem, according to Susan Frankel, a plant pathologist with the Forest Service. “When you look at forest health and the balance between forest trees and the pathogens that attack them, it does seem, given climate change, pathogens get the better end of the deal,” she told me. Frankel is working with a group of ecologists, funded by the Forest Service’s Western Wildland Environmental Threat Assessment Center, to better understand how climate change will affect tree diseases. In a recent report, they outlined possible impacts….

Washington: Rapid climate change and its potential to intensify droughts and floods could threaten Asia’s rice production and pose a significant threat to millions of people across the region, leading climate specialists and agricultural scientists have warned. South and Southeast Asia are home to more than one-third of the world’s population and half of the world’s poor and malnourished.

Prof Jim Hansen to use lecture at Edinburgh International Science Festival to call for worldwide tax on all carbon emissions
Averting the worst consequences of human-induced climate change is a “great moral issue” on a par with slavery, according to the leading Nasa climate scientist Prof Jim Hansen. He argues that storing up expensive and destructive consequences for society in future is an “injustice of one generation to others”.
In his lecture, Hansen will argue that the challenge facing future generations from climate change is so urgent that a flat-rate global tax is needed to force immediate cuts in fossil fuel use. Ahead of receiving the award ….Hansen will argue in his lecture that current generations have an over-riding moral duty to their children and grandchildren to take immediate action. Describing this as an issue of inter-generational justice on a par with ending slavery, Hansen said: “Our parents didn’t know that they were causing a problem for future generations but we can only pretend we don’t know because the science is now crystal clear. “We understand the carbon cycle: the CO2 we put in the air will stay in surface reservoirs and won’t go back into the solid earth for millennia. What the Earth’s history tells us is that there’s a limit on how much we can put in the air without guaranteeing disastrous consequences for future generations. We cannot pretend that we did not know.”
Hansen said his proposal for a global carbon tax was based on the latest analysis of CO2 levels in the atmosphere and their impact on global temperatures and weather patterns. He has co-authored a scientific paper with 17 other experts, including climate scientists, biologists and economists, which calls for an immediate 6% annual cut in CO2 emissions, and a substantial growth in global forest cover, to avoid catastrophic climate change by the end of the century. The paper, which has passed peer review and is in the final stages of publication by the US journal Proceedings of the National Academy of Sciences, argues that a global levy on fossil fuels is the strongest tool for forcing energy firms and consumers to switch quickly to zero carbon and green energy sources. In larger countries, that would include nuclear power. Under this proposal, the carbon levy would increase year on year, with the tax income paid directly back to the public as a dividend, shared equally, rather than put into government coffers. Because the tax would greatly increase the cost of fossil fuel energy, consumers relying on green or low carbon sources of power would benefit the most as this dividend would come on top of cheaper fuel bills. It would promote a dramatic increase in the investment and development of low-carbon energy sources and technologies…..

ISN’T it interesting that the Arab awakening began in Tunisia with a fruit vendor who was harassed by police for not having a permit to sell food — just at the moment when world food prices hit record highs? And that it began in Syria with farmers in the southern village of Dara’a, who were demanding the right to buy and sell land near the border, without having to get permission from corrupt security officials? And that it was spurred on in Yemen — the first country in the world expected to run out of water — by a list of grievances against an incompetent government, among the biggest of which was that top officials were digging water wells in their own backyards at a time when the government was supposed to be preventing such water wildcatting? As Abdelsalam Razzaz, the minister of water in Yemen’s new government, told Reuters last week: “The officials themselves have traditionally been the most aggressive well diggers. Nearly every minister had a well dug in his house.”
All these tensions over land, water and food are telling us something: The Arab awakening was driven not only by political and economic stresses, but, less visibly, by environmental, population and climate stresses as well. If we focus only on the former and not the latter, we will never be able to help stabilize these societies. Take Syria. “Syria’s current social unrest is, in the most direct sense, a reaction to a brutal and out-of-touch regime,” write Francesco Femia and Caitlin Werrell, in a report for their Center for Climate and Security in Washington. “However, that’s not the whole story. The past few years have seen a number of significant social, economic, environmental and climatic changes in Syria that have eroded the social contract between citizen and government. … If the international community and future policy makers in Syria are to address and resolve the drivers of unrest in the country, these changes will have to be better explored.”
From 2006-11, they note, up to 60 percent of Syria’s land experienced one of the worst droughts and most severe set of crop failures in its history. “According to a special case study from last year’s Global Assessment Report on Disaster Risk Reduction, of the most vulnerable Syrians dependent on agriculture, particularly in the northeast governorate of Hassakeh (but also in the south), ‘nearly 75 percent … suffered total crop failure.’ Herders in the northeast lost around 85 percent of their livestock, affecting 1.3 million people.” The United Nations reported that more than 800,000 Syrians had their livelihoods wiped out by these droughts, and many were forced to move to the cities to find work — adding to the burdens of already incompetent government….. If you ask “what are the real threats to our security today,” said Brown, “at the top of the list would be climate change, population growth, water shortages, rising food prices and the number of failing states in the world. As that list grows, how many failed states before we have a failing global civilization, and everything begins to unravel?” Hopefully, we won’t go there. But, then, we should all remember that quote attributed to Leon Trotsky: “You may not be interested in war, but war is interested in you.” Well, you may not be interested in climate change, but climate change is interested in you. Folks, this is not a hoax. We and the Arabs need to figure out — and fast — more ways to partner to mitigate the environmental threats where we can and to build greater resiliency against those where we can’t. Twenty years from now, this could be all that we’re talking about.

TREES are on the front lines of our changing climate. And when the oldest trees in the world suddenly start dying, it’s time to pay attention. North America’s ancient alpine bristlecone forests are falling victim to a voracious beetle and an Asian fungus. In Texas, a prolonged drought killed more than five million urban shade trees last year and an additional half-billion trees in parks and forests. In the Amazon, two severe droughts have killed billions more.
The common factor has been hotter, drier weather. We have underestimated the importance of trees. They are not merely pleasant sources of shade but a potentially major answer to some of our most pressing environmental problems. We take them for granted, but they are a near miracle. In a bit of natural alchemy called photosynthesis, for example, trees turn one of the seemingly most insubstantial things of all — sunlight — into food for insects, wildlife and people, and use it to create shade, beauty and wood for fuel, furniture and homes. For all of that, the unbroken forest that once covered much of the continent is now shot through with holes. …A big question is, which trees should we be planting? Ten years ago, I met a shade tree farmer named David Milarch, a co-founder of the Champion Tree Project who has been cloning some of the world’s oldest and largest trees to protect their genetics, from California redwoods to the oaks of Ireland. “These are the supertrees, and they have stood the test of time,” he says. Science doesn’t know if these genes will be important on a warmer planet, but an old proverb seems apt. “When is the best time to plant a tree?” The answer: “Twenty years ago. The second-best time? Today.”

(04-12) 13:51 PDT San Francisco (AP) — Business leaders and Sen. Dianne Feinstein are launching a $1 billion fundraising effort designed to prevent some of Silicon Valley’s leading technology companies from going underwater — literally. The corporate campuses of Facebook, Google and other high-tech ventures sit on land that once was part of San Francisco Bay.
Planners say those sites and thousands of homes are at risk of catastrophic flooding due to a climate change-fueled sea level rise. For protection, Feinstein is joining a coalition of business groups on Thursday to discuss replacing the century-old levees that contain the bay’s tidal waters with a stronger levee system. Steve McCormick, president of the Gordon and Betty Moore Foundation, says the coalition anticipates that half of the money for the project would come from the federal government and another quarter from the state.
April 10, 2012 ATTEMPTS to slow down climate change by large-scale geo-engineering present ”serious risks” and are unlikely to replace the need to cut greenhouse gas emissions, Australia’s chief scientist has warned. In an overview of schemes proposed by scientists, researchers at the Office of the Chief Scientist say the main methods of planetary-scale engineering would confront big problems with technical feasibility, political co-operation and cost. But research should be pursued in the hope of developing last-ditch methods to slow climate change. ”Given the difficulty in implementing global action to reduce CO2 emissions from human activities and their continued growth, geo-engineering is one possible approach to combat global warming,” it said. ”Geo-engineering would not moderate all the effects of rising emissions, and will introduce its own risks and uncertainties. ”Humans already play a role in dictating the Earth’s climate by adding greenhouse gases to the atmosphere – raising carbon dioxide levels by about 40 per cent since the Industrial Revolution – and by clearing forests to reduce the amount of carbon the land absorbs. But the deliberate management of global climate is still confined to theory, backed by a few small-scale experiments. The report divides geo-engineering solutions to climate change into two basic types – plans to suck carbon dioxide out of the atmosphere and plans to block some of the sun’s heat before it gets here. They include fertilising the oceans with iron filings, to stimulate the growth of algae, which absorbs CO2 and then sinks to the ocean floor, and sowing the atmosphere with sulphates, which deflect some of the sun’s rays away from Earth…. The findings of the Australian report are similar to those of recent studies undertaken by Britain’s Royal Society and the US Task Force on Climate Remediation Research.

Two years after state hit by warming-enhanced 1000-year deluge, bill to ‘teach the controversy’ on evolution and global warming becomes law. On Tuesday, Tennessee adopted a law “to prevent school administrators from reining in teachers who expound on alternative hypotheses” to the scientific theories of evolution and climate change.
The National Center for Science Education has said of the primary alternative to evolution — creationism — that “students who accept this material as scientifically valid are unlikely to succeed in science courses at the college level.” I suppose this is some form of natural selection, then, as Tennessee encourages the disinforming of its kids in two of the most important areas they will need to thrive in the 21st century — thrive economically in a world of global competitors who don’t teach anti-science disinformation to their kids and, of course, thrive literally in a world where a livable climate is being destroyed by man-made global warming and a man-made disinformation campaign to delay action. Ironically, the bill was enacted two years after one of the epic extreme weather events in U.S. recorded history devastated one of America’s great cities (see “The Tennessee deluge of 2010: Nashville’s ‘Katrina’ and the dawn of the superflood“).The status quo media barely told the story of Nashville’s Katrina (let alone its link to human-caused climate change), so you may not remember this superstorm unless you are a regular Climate Progress reader. But this one was way off the charts.
Pro-Oil Outside Groups Spend More Than $16 Million On Energy Attack Ads Since January Posted: 12 Apr 2012 06:44 AM PDT
A handful of outside groups, fueled by oil and coal dollars, are committing tens of millions to propel Big Oil to the forefront of the 2012 elections — outspending the Obama campaign on political energy ads by an overwhelming amount. In the first three-and-a-half months of 2012, groups including Americans for Prosperity, American Petroleum Institute, Crossroads GPS, and American Energy Alliance have spent $16,750,000 on energy attack ads. The total amounts to more than $56 million, including the American Clean Coal Coalition’s pledge of $40 million on ads promoting coal. According to a Think Progress analysis, there have been at least $16,750,000 worth in dirty energy ad buys since January…

Some prominent voices at NASA are fed up with the agency’s activist stance toward climate change. 49 former NASA scientists and astronauts sent the following letter asking the agency to move away from climate models and to limit its stance to what can be empirically proven. The letter criticizes the Goddard Institute For Space Studies especially, where director Jim Hansen and climatologist Gavin Schmidt have been outspoken advocates for action.
The press release with attached letter is below….

Washington Connected Landscapes Project: Analysis of the Columbia Plateau Ecoregion” by the Washington Wildlife Habitat Connectivity Working Group (WHCWG) is available at: <http://waconnected.org/columbia-plateau-ecoregion/>.
We have posted an executive summary and the main document which includes introductory materials, methods, results, an overview of important areas for connectivity, and future work. We are also beginning to post appendices. We have 11 focal species appendices: Sharp-tailed Grouse, Greater Sage-Grouse, black-tailed jackrabbit, white-tailed jackrabbit, Townsend’s ground squirrel, Washington ground squirrel, least chipmunk, mule deer, Western rattlesnake, beaver, and tiger salamander. … Modeling results within the appendices include a series of maps: (1) species movement resistance across the Columbia Plateau, (2) habitat, (3) habitat concentration areas and cost-weighted distances from these areas, (4) least-cost path, and cost-weighted distance interpretive maps, and (5) linkage zones. Additional appendices will provide modeling values and interpretive data, GIS data layer background, and focal species selection background. GIS data layers resulting from this project will be posted as well by fall 2012.
The NOAA Ocean Acidification Program Office has been working with the University of Washington and the Integrated Ocean Observing System (IOOS) Regional Association, the Northwest Association of Networked Ocean Observing Systems (NA-NOOS), to convene two invitational workshops in 2012, one on integrating ocean acidification (OA) data management for the nation, and one on defining a global network for OA monitoring. Libby Jewett (NOAA OA), Dick Feely (NOAA PMEL), and Jan Newton (UW & NANOOS) are working with others to plan and conduct these two workshops.
The OA data management workshop was held March 13-15, 2012 in Seattle, WA, and hosted representatives from NOAA National Oceanographic Data Center (NODC), NOAA Fisheries, Observation and Modeling groups, IOOS, the NSF-funded Biological and Chemical Oceanography Data Management Office (BCO-DMO), the NSF-funded Ocean Observatories Initiative (OOI), NASA, the Ocean Biogeographic Information System (OBIS) USA, USGS, the DOE Carbon Dioxide Information Analysis Center (CDIAC), OceanSITES, and various investigators involved in observations, experiments, modeling, and satellite research. The goal of the workshop was to establish a framework for the handling of ocean acidification data that makes it possible for users to locate, understand and utilize relevant data in support of scientific research and resource management. Outcomes will include a shared vision for integrated OA data management and an initial OA Integrated Data Management Plan with an emphasis on near-term (2-year) goals. The OA monitoring workshop will be held June 26-28, 2012 in Seattle, WA, and will include representatives from around the world. The principal goals of this international workshop are to: (1) design the components and locations of an international ocean acidification observing network that includes repeat hydrographic surveys, underway measurements on volunteer observing ships, moorings, floats, and gliders, leveraging existing networks and programs wherever possible; (2) identify measurement parameters and performance metrics for each major component of the observing system; and (3) develop a strategy for data quality assurance and distribution. The results of both workshops will be summarized in future editions of this newsletter. In the meantime, for more information, please contact Jan Newton.

California: Can a Sustainable Town Be Built From Scratch in the Middle of Nowhere? Travertine Point is a proposed new town that aims to house about 37,000 people, their jobs and the commercial activity to sustain their economy on the northwest shores of the deeply troubled Salton Sea in the Colorado Desert of Southern California. Long-simmering restoration plans are now looking toward development – and even controversial projects like Travertine Point – to help generate some of the likely multi-billion dollar cost of bringing this sea back to life.

In a cavernous London conference center so devoid of life as to seem a film set for “The Matrix,” 3,000 scientists, officials and members of civil society organizations met in the last week of March to consider the state of the planet and what to do about it. The Planet Under Pressure conference is intended to feed directly into the “Rio+20” United Nations Conference on Sustainable Development this coming June, 20 years after the Earth Summit in Rio convened the largest number ever of heads of state and produced, among other things, two international conventions, one for climate change and the other for biological diversity. While it is not as if nothing has been achieved in the interim or that scientific understanding has stood still, it is obvious that new science is not needed to conclude that humanity has failed to act at the scale and with the urgency needed. …

The word’s just come down that Matt Damon’s new movie The Promised Land, which apparently centers around a salesman and a small town, apparently is also about the environmental impact of hydraulic fracturing, and it’s already become a football in the war over the natural gas extraction process. A pro-fracking group is already trying to raise money for a movie of their own off the existence of The Promised Land. And while Damon is well-known as a committed environmentalist, the movie seems likely to be taken as a referendum for how John Krasinski and Dave Eggers, who wrote the script, and Gus Van Sant, who will direct, feel about fracking. All of which is a distraction from the real issue—a lot of our most critical environmental issues and most invasive energy-extraction processes would make for stellar movies and action sequences, and we ought to have more of them….
