Indonesia to tap volcano power
Indonesia is a country of 17,000 islands; the archipelago contains 265 volcanoes, estimated to hold around 40 percent of the world’s geothermal energy potential; investors, the World Bank, and the Indonesian government embark on an ambitious plan to add 4,000 megawatts of geothermal capacity — up from the existing 1,189 megawatts — by 2014, and 9,500 megawatts by 2025, by tapping the volcanoes

Federal loans notwithstanding, Georgia nuclear power plant faces hurdles
The Obama administration has signaled its interest in expanding the U.S. domestic nuclear power industry by giving $8.3 billion in loan guarantees for a Georgia nuclear power plant expansion; critics say that the American tax-payer is at risk; that the original nuclear reactor design has been rejected by the NRC, and that there is no solution for the nuclear waste problem

Cold war offered odd benefit: it limited species invasions
During the cold war, when an Iron Curtain divided the European continent, there were few introduced bird species in Western Europe; following the collapse of the Soviet Union and the removal of the Iron Curtain, trade and the movement of people between east and west increased – and with it the introduction of non-native bird species; these non-native species do not have natural enemies in the local habitat, so they do damage to agriculture and domestic birds, and carry disease

Climate change experts argue for international geoengineering effort
Solar-radiation management (SRM) would involve releasing megatons of light-scattering aerosol particles in the upper atmosphere to reduce Earth’s absorption of solar energy, thereby cooling the planet; another technique would be to release particles of sea salt to make low-altitude clouds reflect more solar energy back into space; long-established estimates show that SRM could offset this century’s predicted global average temperature rise more than 100 times more cheaply than achieving the same cooling by cutting emissions

Experts: U.K. must act now to prepare for rising sea level
A joint study by the leading U.K. civil engineering and architectural associations says that steps must be taken now to protect coastal towns from rising sea levels; the reports says policy makes should consider three options for tackling rising sea level: “retreat” — moving critical infrastructure and housing to safer ground; “defend” — building town or city-wide sea defenses; and “attack” — extending the existing coastline and building out on to the water

Maximum height of extreme waves up dramatically in Pacific Northwest
A new assessment concludes that the highest waves in a “100-year event” along the Pacific Northwest’s coast may be as much as 46 feet, up from estimates of only 33 feet that were made as recently as 1996, and a 40 percent increase; the new findings raise special concerns for flooding, coastal erosion, and structural damage; “The Pacific Northwest has one of the strongest wave climates in the world, and the data clearly show that it’s getting even bigger,” says one of scientists involved

Large dams linked to more extreme weather patterns
A new study looked at the magnitude of the biggest storms near 633 of the world’s largest dams before and after construction; they found that in many places the level of precipitation in the most extreme rainfall events grew by an average of 4 percent per year after a dam was built, with the relationship especially strong in semi-arid regions

Scientists seek homes in the Seattle area in which to install quake monitors
Scientists want to install seismic monitors in homes in the Seattle area to measure ground-shaking; with detailed information on the way the ground shakes in a particular spot, it may be possible to design buildings tailored to their exact locations; the instruments also will help construct “shake-maps” to pinpoint areas of heaviest damage after major earthquakes

Rise in sea levels forces drastic changes on Florida
If sea levels rise by only two feet, Florida stands to lose almost 10 percent of its land area and the homes of 1.5 million people; the zone which is vulnerable to 27-inch rise in sea level includes residential real estate worth $130 billion, half of Florida’s beaches, two nuclear reactors, three prisons, 37 nursing homes, and much more; the Florida government is considering changes to building codes and other precautionary measures.

Rise in sea levels threatens California ports, infrastructure
Scientists expect ocean levels to rise by at least 16 inches over the next 40 years, causing flooding and endangering facilities throughout the state of California; the California Climate Change Center has estimated that nearly half a million people, thousands of miles of roads and railways, and major ports, airports, power plants, and wastewater treatment plants are at risk; in the Los Angeles-Long Beach-Santa Ana region, sea level rise could expose $96.5 billion of infrastructure to damage.

Climate change threatens Canada North's infrastructure
Climate change is felt more acutely in the arctic, and a Canadian government’s report says that winter roads melting earlier in the spring could force communities to airlift supplies, while increased snowfall and changing ice conditions can add stress to buildings as well as energy and communications infrastructure

Dutch build sand dunes to fight rising seas
More than eighteen million cubic meters of sand are dredged from the bottom of the ocean and brought back to land to form new dunes; the new dunes — each 30 to 60 meters wide, and rising up to 10 meters above sea level — are built along a 20-kilometer stretch of the shore
