Thatcher Chemical fined for violations of Clean Air Act Risk Management regulations
January 21, 2011 06:54 AM - Roger Greenway, ENN
The federal Clean Air Act requires facilities that have on site more than specified quantities of chemicals which could be hazardous to offsite communities to develop Risk Management Plans (RMP) to address ways to safely acquire, store, and use these substances in ways that assure that they are safely used, that employees are appropriately trained, and that first responders and nearby residents are informed of the presence of potentially hazardous chemicals which, if released to the environment, could require evacuation or sheltering in place for offsite residents. As part of its compliance enforcement activities, the EPA has an audit program to visit facilities to assess their level of compliance with the RMP program. EPA reported this week that it conducted compliance inspections of Thatcher Chemical's Salt Lake City facility in February and April of 2010 to assess compliance with the RMP regulations.
CO2 Ocean Sequestration
January 20, 2011 04:54 PM - Andy Soos, ENN
Carbon sequestration is "The process of removing carbon from the atmosphere and depositing it in a reservoir." When carried out deliberately, this may also be referred to as carbon dioxide removal, which is a form of geoengineering. The term carbon sequestration may also be used to refer to the process of carbon capture and storage, where CO2 is removed from flue gases, such as on power stations, before being stored in underground reservoirs. The term may also refer to natural biogeochemical cycling of carbon between the atmosphere and reservoirs, such as by chemical weathering of rocks. Using seawater and calcium to remove carbon dioxide (CO2) in a natural gas power plant's flue stream, and then pumping the resulting calcium bicarbonate in the sea, could be beneficial to the oceans' marine life or states a new research report.
NOAA Rescues Entangled Whale in the Open Sea
January 20, 2011 11:19 AM - David A Gabel, ENN
Earlier this month, scientists with the National Oceanic and Atmospheric Administration (NOAA) managed to save a North Atlantic Right Whale which entangled itself in ropes around its mouth and flippers. They sedated the mighty creature in order to get close enough to cut the ropes. This marks only the second time in which an entangled whale has been sedated in open sea.

For a long time there has been speculation of whether there is or was life on Mars. A really good answer would have been to have one of the Mars rover devices to photograph something moving about and obviously alive. Well that did not happen so a search for more subtle clues of smaller life forms or something from the deep past is in progress. The next rover to be delivered to Mars will contain a SAM. The instrument is Sample Analysis at Mars, or SAM, built by NASA's Goddard Space Flight Center, Greenbelt, Md. At the carefully selected landing site for the Mars rover named Curiosity, one of SAM's key jobs will be to check for carbon-containing compounds called organic molecules, which are among the building blocks of life on Earth. The clean-room suits worn by Curiosity's builders at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are just part of the care being taken to keep biological material from Earth from showing up in results from SAM.
Climate Models Are Becoming Increasingly Accurate
January 19, 2011 09:45 AM - David A Gabel, ENN
Predicting future climates on planet Earth is an extremely hard task due to the myriad of factors involved. To make the necessary calculations requires computers with capacities far beyond the average home computer. However, climate models are become ever more reliable thanks not only to greater computing power, but also to more extensive observation efforts of the current climate, and an improved understanding of the climate system.
Masdar World Future Energy Summit
January 18, 2011 04:36 PM - Andy Soos, ENN
Abu Dhabi, UAE, may be a major oil supplier to the world, but the Emirate is also active with ideas and commitments to a green energy future. The World Future Energy Summit 2011 in Abu Dhabi began on January 17th. The summit is taking place not far from the emerging city of Masdar which is designed to be a showpiece of clean tech innovation and green urban planning. Around 33 official delegations and more than 3,000 delegates will participate in the World Future Energy Summit. Masdar is a project in Abu Dhabi, in the United Arab Emirates. Its core is a planned city, which is being built by the Abu Dhabi Future Energy Company, a subsidiary of Mubadala Development Company, with the majority of seed capital provided by the government of Abu Dhabi. The city will rely entirely on solar energy and other renewable energy sources, with a sustainable, zero-carbon, zero-waste ecology. The city is being constructed 11 miles east-south-east of the city of Abu Dhabi.
Inflammation and How It May be Controlled
January 17, 2011 05:58 PM - Andy Soos, ENN
Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process Scientists have identified a protein that acts as a "master switch" in certain white blood cells, determining whether they promote or inhibit inflammation. The study, published in the journal Nature Immunology, could help researchers look for new treatments for diseases such as rheumatoid arthritis that involve excessive inflammation. Inflammatory responses are an important defense that the body uses against harmful stimuli such as infections or tissue damage, but in many conditions, excessive inflammation can itself harm the body. In rheumatoid arthritis, the joints become swollen and painful, but the reasons why this happens are not well understood.
How Hot Can It Get?
January 14, 2011 01:35 PM - Andy Soos, ENN
In the ancient past temperatures on Earth appeared to have been much warmer than today. It is possible that temperatures may rise as high as then based on current climate change projections. The new study, by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl, will appear as a Perspectives piece in this week’s issue of the journal Science. Building on recent research, the study examines the relationship between global temperatures and high levels of carbon dioxide in the atmosphere tens of millions of years ago. It warns that, if carbon dioxide emissions continue at their current rate through the end of this century, atmospheric concentrations of the greenhouse gas will reach levels that last existed about 30 million to 100 million years ago, when global temperatures averaged about 29 degrees F higher than now (in the high eighties F).
NOAA's Weatherman in the Sky
January 14, 2011 11:20 AM - David A Gabel, ENN
Forecasting the weather can be a tricky business, especially in winter. When a winter storm approaches, forecasts can range widely across the board from light flurries to a blizzard. As many know, the jet stream over the North American continent moves west to east. That is why the National Oceanic and Atmospheric Administration (NOAA) is dispatching its state of the art aircraft to gather atmospheric data over the North Pacific Ocean, the region where North America's weather originates.

Hanny's Voorwerp which is Dutch for Hanny's object, is an astronomical object of unknown nature. It was discovered in 2007 by Dutch school teacher Hanny van Arkel, while she was participating as an amateur volunteer in the Galaxy Zoo project. Photographically, it appears as a bright blob close to spiral galaxy IC 2497 in the constellation Leo Minor. The object, now referred to as a "voorwerp", is about the size of our Milky Way galaxy and has a huge central hole over 16,000 light years across. The voorwerp is false colored green, a standard color to represent the presence of several luminous emission lines of glowing oxygen. It has been shown to be at the same distance from Earth as the adjacent galaxy, both about 650 million light-years away. Hanny's Voorwerp may be a small part of a 300,000-light-year-long streamer of gas, located about 650 million light-years from Earth. Scientists suggested that a quasar in a nearby galaxy, known as IC 2497, was shining on Hanny's Voorwerp, lighting up the oxygen in the streamer with a greenish glow. The only problem was that no quasar could be seen.
