Treasure Island Radiation More Widespread than Reported [20Aug12] - 0 views

  • Radioactive contamination at the Treasure Island Naval Station, where San Francisco plans to build a high-rise community for 20,000 residents, is more widespread than previously disclosed, according to a new U.S. Navy report and other documents obtained by The Bay Citizen.
  • The draft report, dated Aug. 6, marks the first time the Navy has fully acknowledged that the island, created from landfill in 1937, was used as a repair and salvage operation for a Pacific fleet exposed to atomic blasts during the Cold War. The report came in response to state regulators, who pressed for details after cleanup workers found radioactive waste in unexpected locations.
  • Known potential sources of radiation on the island included a nuclear training ship intentionally doused in radiation and even glow-in-the-dark buttons handed out at the 1939-1940 Golden Gate International Exposition held on the island.

The Arctic Ice Crisis | Politics News | Rolling Stone - 0 views

  • Fresh snow bounces back 84 percent of the light that hits it; warm, rounded crystals can reflect as little as 70 percent. Slushy snow saturated by water – which gives it a gray cast, or even a bluish tint – reflects as little as 60 percent. Add dust or soot, and the albedo drops below 40 percent. Box's satellite data has shown a steady darkening in Greenland's albedo, from a July average of 74 percent when the century began to about 68 percent last year. And then came this summer: Without warning, the line on the albedo chart dropped deep into uncharted territory. At certain altitudes, the ice sheet in Greenland was suddenly four percent less reflective – in a single season.
  • But the future, pressing as it is, sometimes gives way to sheer awe at the scale of what we've already done. Simply by changing the albedo of the Greenland ice sheet, Box calculates, the island now absorbs more extra energy each summer than the U.S. consumes in a year. The shape and color of the ice sheet's crystals, in other words, are trapping more of the sun's rays than all the cars and factories and furnaces produce in the world's biggest economy. One of Box's collaborators, photographer James Balog, puts it like this: "Working in Greenland these past years has left me with a profound feeling of being in the middle of a decisive historic moment – the kind of moment, at least in geologic terms, that marks the grand tidal changes of history." Amid this summer's drama of drought, fire and record heat, the planet's destiny may have been revealed, in a single season, by the quiet metamorphosis of a silent, empty sheet of ice.

Climate change is here - and worse than we thought - The Washington Post - 0 views

  • In a new analysis of the past six decades of global temperatures, which will be published Monday, my colleagues and I have revealed a stunning increase in the frequency of extremely hot summers, with deeply troubling ramifications for not only our future but also for our present.
  • The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year can each be attributed to climate change. And once the data are gathered in a few weeks’ time, it’s likely that the same will be true for the extremely hot summer the United States is suffering through right now.
  • Our new peer-reviewed study, published by the National Academy of Sciences, makes clear that while average global temperature has been steadily rising due to a warming climate (up about 1.5 degrees Fahrenheit in the past century), the extremes are actually becoming much more frequent and more intense worldwide.
  • ...1 more annotation...
  • Extremely hot temperatures covered about 0.1 percent to 0.2 percent of the globe in the base period of our study, from 1951 to 1980. In the last three decades, while the average temperature has slowly risen, the extremes have soared and now cover about 10 percent of the globe.

"A Staggering Mess" as Tsunami Debris Hits Alaska Coast Early [01May12] - 0 views

  • a non-profit organization that estimates it has cleared nearly 1,000,000 pounds of plastic debris from Alaskan coasts over the past 10 years, is reporting “tons” of what it believes is likely tsunami debris washing up on the coasts of the Kayak and Montague islands. Chris Pallister, president of Gulf of Alaska Keeper, told Alaska’s KTUU TV that ““It’s a staggering mess [...] the magnitude of this is just hard to comprehend and I’ve been looking at this stuff a long time.
  • In my opinion, this is the single greatest environmental pollution event that has ever hit the west coast of North America. The slow-motion aspects of it have fooled an unwitting public. It far exceeds the Santa Barbara or Exxon Valdez oil spills in gross tonnage and also geographic scope. (I was in Prince William Sound during the during the Exxon Valdez oil spill and so have a sense of comparison). Tens of thousands of miles of coastline from California to the Aleutian Islands are going to be hit with billions of pounds of toxic debris. NOAA’s latest estimate is that 1.5 million tons of largely plastic debris will hit the western United States coast. That is 30 billion pounds. We expect Alaska to get the largest percentage of that with much of it lodging on northern Gulf of Alaska beaches. Most of this will be plastic which is full of inherent toxic chemicals that will leach into the environment for generations.
  • Possibly worse are the millions of containers full of anything from household chemicals to toxic industrial chemicals that are floating our way. They will eventually burst upon our shores…in sensitive inter-tidal spawning and rearing habitat, endangering shorebirds, marine mammals, fish and everything in between. We are already finding empty and partially full containers of tsunami related chemicals and fuel drums along the northern Gulf of Alaska shoreline. The heavier fuller containers will come later because the wind doesn’t push them as fast toward the Gulf of Alaska as they are more current driven. The light-weight, high-windage debris such as Styrofoam, buoys, bottles, empty containers and drums have already arrived in staggering quantities

Deepwater Horizon Oil Spill Contaminated Ocean's Food Chain, Study Finds -- Health & We... - 0 views

  • A recent study has confirmed that toxic compounds derived from oil that was released in the Deepwater Horizon spill that occurred in the Gulf of Mexico nearly two years ago has entered the ocean's food chain through microorganisms.
  • The study, funded by the National Science Foundation and led by a team of researchers from East Carolina University, the University of Maryland Center for Environmental Science, Oregon State University, Georgia Institute of Technology, and the U.S. Geological Survey, detected chemical compounds found in oil called hydrocarbons, some known to be carcinogenic, within the bodies of microscopic crustaceans called zooplankton.
  • "Our research helped to determine a 'fingerprint' of the Deepwater Horizon spill--something that other researchers interested in the spill may be able to use," Dr. Siddhartha Mitra of East Carolina University said in a statement. "Furthermore, our work demonstrated that zooplankton in the Northern Gulf of Mexico accumulated toxic compounds derived from the Macondo well." Zooplankton form the base of the ocean's food web and are typically fed upon by fish larva and smaller crustaceans, said Dr. David Kimmel of East Carolina University. Whether or not these larger organisms have accumulated significant amounts of toxic compounds, or has entered the human food chain, has yet to be determined. "That is certainly one of the questions we would like to see answered with more research," said Dr. Mitra in a phone interview.

Nuclear Risks at Bed, Bath & Beyond Show Dangers of Scrap [20Mar12] - 0 views

  • The discovery of radioactive tissue boxes at Bed, Bath & Beyond Inc. (BBBY) stores in January raised alarms among nuclear security officials and company executives over the growing global threat of contaminated scrap metal.
  • While the U.S. home-furnishing retailer recalled the boutique boxes from 200 stores nationwide without any reports of injury, the incident highlighted one of the topics drawing world leaders to a nuclear security meeting in Seoul on March 26-27. The bi-annual summit, convened by President Barack Obama for the first time in 2010, seeks to stem the flow of atomic material that has been lost, stolen or discarded as trash.
  • As U.S. and European leaders tackle the proliferation of weapons-grade uranium or plutonium in countries like Iran and North Korea, industries are confronting the impact of loose nuclear material in an international scrap-metal market worth at least $140 billion, according to the Brussels-based Bureau of International Recycling. Radioactive items used to power medical, military and industrial hardware are melted down and used in goods, driving up company costs as they withdraw tainted products and threatening the public’s health. ‘Major Risk’ “The major risk we face in our industry is radiation,” said Paul de Bruin, radiation-safety chief for Jewometaal Stainless Processing BV, one of the world’s biggest stainless- steel scrap yards. “You can talk about security all you want, but I’ve found weapons-grade uranium in scrap. Where was the security?”

  • The supposed ‘consensus’ on man-made global warming is facing an inconvenient challenge after the release of new temperature data showing the planet has not warmed for the past 15 years.The figures suggest that we could even be heading for a mini ice age to rival the 70-year temperature drop that saw frost fairs held on the Thames in the 17th Century.Based on readings from more than 30,000 measuring stations, the data was issued last week without fanfare by the Met Office and the University of East Anglia Climatic Research Unit. It confirms that the rising trend in world temperatures ended in 1997.
  • Meanwhile, leading climate scientists yesterday told The Mail on Sunday that, after emitting unusually high levels of energy throughout the 20th Century, the sun is now heading towards a ‘grand minimum’ in its output, threatening cold summers, bitter winters and a shortening of the season available for growing food.Solar output goes through 11-year cycles, with high numbers of sunspots seen at their peak. We are now at what should be the peak of what scientists call ‘Cycle 24’ – which is why last week’s solar storm resulted in sightings of the aurora borealis further south than usual. But sunspot numbers are running at less than half those seen during cycle peaks in the 20th Century.
  • Analysis by experts at NASA and the University of Arizona – derived from magnetic-field measurements 120,000 miles beneath the sun’s surface – suggest that Cycle 25, whose peak is due in 2022, will be a great deal weaker stil

Arctic Ocean freshwater bulge detected [22Jan12] - 0 views

  • UK scientists have detected a huge dome of freshwater that is developing in the western Arctic Ocean. The bulge is some 8,000 cubic km in size and has risen by about 15cm since 2002. The team thinks it may be the result of strong winds whipping up a great clockwise current in the northern polar region called the Beaufort Gyre. This would force the water together, raising sea surface height, the group tells the journal Nature Geoscience.
  • The data (1995-2010) indicates a significant swelling of water in the Beaufort Gyre, particularly since the early part of the 2000s. The rising trend has been running at 2cm per year.
  • A lot of research from buoys and other in-situ sampling had already indicated that water in this region of the Arctic had been freshening. This freshwater is coming in large part from the rivers running off the Eurasian (Russian) side of the Arctic basin. Winds and currents have transported this freshwater around the ocean until it has been pulled into the gyre. The volume currently held in the circulation probably represents about 10% of all the freshwater in the Arctic.
  • ...2 more annotations...
  • "When you have clockwise rotation - the freshwater is stored. If the wind goes the other way - and that has happened in the past - then the freshwater can be pushed to the margins of the Arctic Ocean
  • "If the spin-up starts to spin down, the freshwater could be released. It could go to the rest of the Arctic Ocean or even leave the Arctic Ocean." If the freshwater were to enter the North Atlantic in large volumes, the concern would be that it might disturb the currents that have such a great influence on European weather patterns. These currents draw warm waters up from the tropics, maintaining milder temperatures in winter than would ordinarily be expected at northern European latitudes.

Climate May Be Less Sensitive To CO2 Than Previously Thought [25Nov11] - 0 views

  • "A new study suggests that the effects of rising levels of carbon dioxide on temperature may be less significant than previously thought. 'The new models predict that given a doubling in CO2 levels from pre-industrial levels, the Earth's surface temperatures will rise by 1.7 to 2.6 degrees C. That is a much tighter range than suggested by the Intergovernmental Panel on Climate Change's 2007 report, which suggested a rise of between 2 to 4.5 degrees C."

Coral reefs 'will be gone by end of the century' [11Sep11] - 0 views

  • "a new first for mankind – the 'extinction' of an entire ecosystem"
  • The predicted decline is mainly down to climate change and ocean acidification, though local activities such as overfishing, pollution and coastal development have also harmed the reefs.

New, convincing evidence indicates global warming is caused by cosmic rays and the sun ... - 0 views

  • The science is now all-but-settled on global warming, convincing new evidence demonstrates, but Al Gore, the IPCC and other global warming doomsayers won’t be celebrating. The new findings point to cosmic rays and the sun — not human activities — as the dominant controller of climate on Earth.
  • The research, published with little fanfare this week in the prestigious journal Nature, comes from über-prestigious CERN, the European Organization for Nuclear Research, one of the world’s largest centres for scientific research involving 60 countries and 8,000 scientists at more than 600 universities and national laboratories. CERN is the organization that invented the World Wide Web, that built the multi-billion dollar Large Hadron Collider, and that has now built a pristinely clean stainless steel chamber that precisely recreated the Earth’s atmosphere.
  • The hypothesis that cosmic rays and the sun hold the key to the global warming debate has been Enemy No. 1 to the global warming establishment ever since it was first proposed by two scientists from the Danish Space Research Institute, at a 1996 scientific conference in the U.K. Within one day, the chairman of the Intergovernmental Panel on Climate Change, Bert Bolin, denounced the theory, saying, “I find the move from this pair scientifically extremely naive and irresponsible.” He then set about discrediting the theory, any journalist that gave the theory cre dence, and most of all the Danes presenting the theory — they soon found themselves vilified, marginalized and starved of funding, despite their impeccable scientific credentials.
  • ...4 more annotations...
  • In this chamber, 63 CERN scientists from 17 European and American institutes have done what global warming doomsayers said could never be done — demonstrate that cosmic rays promote the formation of molecules that in Earth’s atmosphere can grow and seed clouds, the cloudier and thus cooler it will be. Because the sun’s magnetic field controls how many cosmic rays reach Earth’s atmosphere (the stronger the sun’s magnetic field, the more it shields Earth from incoming cosmic rays from space), the sun determines the temperature on Earth.
  • The mobilization to rally the press against the Danes worked brilliantly, with one notable exception. Nigel Calder, a former editor of The New Scientist who attended that 1996 conference, would not be cowed. Himself a physicist, Mr. Calder became convinced of the merits of the argument and a year later, following a lecture he gave at a CERN conference, so too did Jasper Kirkby, a CERN scientist in attendance. Mr. Kirkby then convinced the CERN bureaucracy of the theory’s importance and developed a plan to create a cloud chamber — he called it CLOUD, for “Cosmics Leaving OUtdoor Droplets.”
  • But Mr. Kirkby made the same tactical error that the Danes had — not realizing how politicized the global warming issue was, he candidly shared his views with the scientific community.
  • “The theory will probably be able to account for somewhere between a half and the whole of the increase in the Earth’s temperature that we have seen in the last century,” Mr. Kirkby told the scientific press in 1998, explaining that global warming may be part of a natural cycle in the Earth’s temperature.

Midwest Floods: Both Nebraska Nuke Stations Threatened [17Jun11] - 0 views

  • Continued flooding does threaten the plants, however. As nuclear engineer Arnie Gundersen explains in the above video, cooling pumps must operate continuously, even years after a plant is shut down. One group, the Foundation for Resilient Societies, has proposed solar panels and other high-reliability power sources to supply backup cooling for the fuel pools at nuclear plants.
  • While hindsight might be 20/20, the lack of foresight can be blindingly deadly when it comes to radioactive waste that lasts tens of thousands of years for the measly prize of 40 years of electricity.
  • “Ft. Calhoun is the designated spent fuel storage facility for the entire state of Nebraska…and maybe for more than one state. Calhoun stores its spent fuel in ground-level pools which are underwater anyway – but they are open at the top. When the Missouri river pours in there, it’s going to make Fukushima look like an x-ray.

Climategate part 2? A worrying conflict of interest [17Jun11] - 0 views

  • a press release for the report which suggested that renewable sources alone, without nuclear power, could provide 77 per cent of the world’s energy supply by 2050.
  • The supporting documents, which weren’t released until over a month later, reveal that this claim was based on a large real-terms decline in worldwide energy consumption over the next 40 years (highly unrealistic as India and China grow their economies).
  • Now it appears that there are more apparent conflicts of interest in the IPCC’s energy report
  • ...9 more annotations...
  • eter Bosshard, Policy Director of the campaign group International Rivers, contacted me to point out that the scenario for 77 per cent renewables included (against standard practice) large hydropower projects among the technologies to be promoted.
  • Most environmentalists believe that more large scale dams are not the right approach to generating electricity in a sustainable way.
  • While water is a renewable resource, the ecosystems that are destroyed by hydropower projects are not. Not least due to dam building, rivers, lakes and wetlands suffer from a higher rate of species extinction than any other major ecosystem.
  • Not only this but because of the decomposing organic matter found in reservoirs, dams emit greenhouse gases such as methane and CO2. In some cases, it is claimed, these emissions can be higher than those of thermal power projects with the same electricity output.
  • Ivan Lima of Brazil’s National Institute for Space Research  estimate that the total methane emissions from large dams at 104 million tons per year.
  • Methane is a particularly potent greenhouse gas, and Lima’s figure amounts to more than 4 per cent of the total warming impact of human activities – roughly equal to the climate impact of the global aviation sector
  • So why is the IPCC contravening international standard practice to promote hydropower?
  • Well this may be total coincidence but in addition to several independent scientists, the IPCC selected a number of authors to write the section of hydropower who have a vested interest in growing the sector.
  • Of the nine lead authors there are representatives of two of the world’s largest hydropower developers, a hydropower consultancy, and three agencies promoting hydropower at the national level.
  •  
    The UN's Intergovernmental Panel on Climate Change has been compromised again.
