In recent years, climate scientists, particularly those involved in communicating the risks of anthropogenic climate change to the public, have faced increasing levels of vitriol from politicians, pundits and the public alike. The news earlier this year that leading Australian climate scientists were receiving death threats, in the midst of a fierce debate on the implementation of a carbon tax, is just the latest escalation.
In 2007, 11 retired admirals and generals from the U.S. armed forces published a report arguing that global climate changes represented a major threat to global security. That same year, U.N. Secretary-General Ban Ki-moon argued in a Washington Post op-ed that the ongoing Sudanese civil conflict was, in part, attributable to climatic changes. By combining new techniques from climate physics and econometrics, my colleagues and I have found evidence that there is some truth in these statements. Indeed, the global climate can influence the outbreak of civil wars.
Researchers flying over West Antarctica last month were at the right place at the right time, spotting an actively growing rift that they expect will spawn an iceberg about 10 times the size of Manhattan.
Lessons Learned From a Cross-country Road Trip in a Natural Gas Vehicle
In what seems like a replay of a bad 1970s movie — with high oil prices, prominent energy security risks, and fluctuating emissions regulations — Americans are looking for alternatives to gasoline. But this time around, many industrial proponents, investors, experts and energy enthusiasts claim they have a solution: natural gas
Since their introduction in the early 1980s, geotextile structures have gained popularity in the engineering community and are now being used for a variety of geotechnical engineering applications. Geotextiles were originally developed as permeable reinforcement for soils in landscape applications. Woven and nonwoven geotextiles, known for their strength and permeability, are typically made from the synthetic polymers polypropylene and polyester, but natural fibers like coir and jute are becoming more popular.
During the past year, many of the 386,000 inhabitants of New Zealand’s second-largest city, Christchurch, have thought and said one phrase over and over again: “When will it stop?” Starting in September 2010, several major earthquakes and more than 8,000 aftershocks have rocked the city and region. Rebuilding has started, been interrupted, started again and been halted again. People have been living without water, sewer, roads, offices and homes for so long that it may be hard to remember what “normal” is.
Even though the inhabitants of Christchurch (Cantabrians) have had a nonstop year of hardships, they have kept their humor. A local named Bruce Raines started a “You know you are from Christchurch when…” Facebook page and solicited comments, from which he then published a book.
