Exploring America’s, and the World’s, Energy Choices

Fresh explorations of energy options, from fracking to conservation.......The New York Times sponsored a “Energy For Tomorrow” forum this week to clarify the country’s and world’s energy options in an era of economic turbulence and a changing climate. The participants including Secretary of Energy Steve Chu. A broad theme was the need for an “all of the above” energy quest (a mantra of President Obama).

800,000 years of abrupt climate variability: Earth’s climate is capable of very rapid transitions

800,000 years of abrupt climate variability: Earth's climate is capable of very rapid transitions An international team of scientists has produced a prediction of what climate records from Greenland might look like over the last 800,000 years. The team's reconstruction is based on the much longer ice core temperature record retrieved from Antarctica and uses a mathematical formulation to extend the Greenland record beyond its current limit.

New seismic hazard assessment for Central America

A new study evaluates the seismic hazards for the entire Central America, including specific assessments for six capital cities, with the greatest hazard expected for Guatemala City and San Salvador, followed by Managua and San Jose, and notably lower in Tegucigalpa and Panama City.

Young People Tired of Old Economic Models

Young people press for approaches to pursuing progress that can fit on a finite planet.......environmental restraint must be limited and gradual, while social spending must be contained, otherwise the economy will not grow and we will all suffer. This kind of thinking is pervasive, dangerous, and outdated. Infinite growth in a finite world is impossible, growth based on speculative finance is unstable, and since the 1960’s, GDP growth and self-reported well-being have been completely uncorrelated phenomena. In this sense holistic, deep-reaching change of both thought, education and practice is needed....... This is a syndicated post, which originally appeared at Dot EarthView original post.

By 2050 or so, the human population is expected to reach nine billion, essentially adding two Chinas to the number of people alive today. Those billions will be seeking food, water and other resources on a planet where, scientists say, humans are already shaping climate and the web of life. In Dot Earth, which recentlymoved from the news side of The Times to the Opinion section, Andrew C. Revkin examines efforts to balance human affairs with the planet’s limits......from

Katrina changed everything: New software predicts how flood water will spread

All over the country, millions of Americans still live behind dams or levees, and if these were to fail and unleash catastrophic flooding, as some did in New Orleans in 2005, property and life might once again pay the price. Now there is some remarkable software to help swiftly predict how the water will spread. This is a syndicated post, which originally appeared at ScienceDaily: Natural Disaster NewsView original post. April 18, 2012. Dr. Uddin's note: University of Mississippi NCCHE's Dr. Mustafa Altinakr and colleagues are the developers of the flood mapping software featured in this DHS story.

First-of-its-kind study reveals surprising ecological effects of earthquake and tsunami

The reappearance of long-forgotten habitats and the resurgence of species unseen for years may not be among the expected effects of a natural disaster. Yet that's exactly what researchers have found on the sandy beaches of south central Chile, after an 8.8-magnitude earthquake and devastating tsunami in 2010. Their study also revealed a preview of the problems brought by sea level rise –– a major symptom of climate change.
