Improved weather, climate predictions strengthen the U.S. economy
The economic costs of damaging weather events have an immense and increasing impact on the U.S. economy. These costs could be anticipated and mitigated by improved weather and climate predictions, say a range of experts in the public and private sectors. These experts will meet in early April in an American Meteorological Society event to discuss the economic benefits of how environmental forecast, prediction, and observation programs and services strengthen the U.S. economy.

New technology for carbon-dioxide capture, clean coal reaches milestone
An innovative new process which releases the energy in coal without burning — while capturing carbon dioxide, the major greenhouse gas — has passed a milestone on the route to possible commercial use.

Instead of a renaissance, U.S. nuclear energy industry is facing tough times
Five years ago, U.S. nuclear industry executives and energy industry analysts talked about an American nuclear renaissance, with up to twenty new reactors to be added to the nation’s stock. Things are very different today, however, and the U.S. nuclear energy industry, rather than expanding, is fighting to hold on.

NRC rejects plan for Maryland nuclear reactor
A plan to build a third nuclear reactor in southern Maryland was postponed last week as the Nuclear Regulatory Commission (NRC) upheld an earlier decision to squash the project. the primary reason for the rejection is the fact that the applicant’s parent company, Electricite de France, is 85 percent owned by the French government. U.S. law forbids foreign ownership of U.S. nuclear reactors.

Does warmer climate mean stormier, or only wetter, weather?
Many scientists argue that the climate has warmed since people began to release massive amounts greenhouse gases to the atmosphere during the Industrial Revolution. These scientists, however, are less sure that warming climate creates stormier weather. The reason: nobody has done the quantitative analysis needed to show this is indeed happening. Until now.

“Dirty blizzard” accounts for missing Deepwater Horizon oil
The Deepwater Horizon disaster spilled more than 200 million gallons of oil into the Gulf of Mexico. Microbes likely processed most of the oil within months of the spill, but these microbes do not account for all of the spilled oil. Scientists have now found what happened to the oil not processed by microbes: the oil acted as a catalyst for plankton and other surface materials to clump together and fall to the sea floor in a massive sedimentation event that researchers are calling a “dirty blizzard.” The oily sediments deposited on the sea floor could cause significant damage to ecosystems and may affect commercial fisheries in the future.

2012 economic losses from disasters set new record at $138 billion
The UN Office for Disaster Risk Reduction (UNISDR) reported that for the first time in history, the world has experienced three consecutive years in which annual economic losses have exceeded $100 billion. The losses are the result of an enormous increase in exposure of industrial assets and private property to extreme disaster events.

Building stronger, greener concrete with biofuel byproducts
The world uses nearly seven billion cubic meters of concrete a year, making concrete the most-used industrial material after water. Even though making concrete is less energy intensive than making steel or other building materials, we use so much of it that concrete production accounts for between 3 to 8 percent of global carbon dioxide emissions.

New structure for regulation of geoengineering research needed: experts
Geoengineering, the use of human technologies to alter the Earth’s climate system — such as injecting reflective particles into the upper atmosphere to scatter incoming sunlight back to space — has emerged as a potentially promising way to mitigate the impacts of climate change. Such efforts, however, could present unforeseen new risks. This inherent tension has thwarted both scientific advances and the development of an international framework for regulating and guiding geoengineering research.

Obama: at least some Chinese cyberattacks on U.S. are “state sponsored”
In an interview to be aired today on ABC News, President Barack Obama said that some, but not necessarily all, cyberattacks on U.S. firms and infrastructure originating in China were “state sponsored.” Obama stressed the need to avoid “war rhetoric” when discussing cyberattacks, and renewed his calls for Congress to strengthen cyber security while protecting civil liberties.

Urgent need to find asteroids that threaten Earth: expert
The impact from a 100-meter long asteroid hitting Earth would be equal to detonating a 100-megaton hydrogen bomb. Several large asteroids have zipped dangerously close to Earth in the past month. There are millions of these near-Earth-orbit (NEOs) asteroids longer than 100 meters. Because they are relatively small, and because they spend so much time far from Earth, scientists tend to find them only by chance.

Russia embarking on a program to thwart asteroid threat
Officials from Rosatom, Russia’s nuclear agency, and from Russia’s space agency, yesterday (Tuesday) told a special conference at the Russian Federation Council, the Russian upper house, that Russia was embarking on an ambitious program – estimated to cost about $2 billion – to shield Russia from the threat of asteroids and meteors. The first steps will be taken by the end of the year, but the comprehensive set of measures will not be available until 2018-20. The officials discussed various possible measures, ranging from planting beacon transmitters on asteroids to megaton-sized nuclear strikes to destroy asteroid or divert them from a course which would lead to a collision with the Earth.

Ohio’s Perry nuclear power plant was vulnerable to sabotage
A report issued last week said that operators at the Perry Nuclear Power Plant in Ohio found a vulnerability in the security of the plant last year, and that that vulnerability could have put the public in harm’s way. The utility operating the nuclear plant reported to the Nuclear Regulatory Commission (NRC) that the plant’s security program for monitoring underground pathways and other unattended openings were insufficient to detect and prevent unauthorized access to the protected area.

Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
