In the words of Maite Nkoana-Mashabane * , President of the Durban UN Climate Change Conference, “ we should not let the perfect become the enemy of the good and the possible .” Given the thousands of fossil fuel-fired power plants around the world (including about 3,000 in North American alone), this good and possible likely means a future that includes coal, natural gas, and oil as primary energy resources. So, how can we use these fossil fuels in a more environmentally responsible way within practical constraints? One option could be found in the flexible operation of carbon capture and sequestration technology on the world s coal-fired power plants

Attention Deficit/Hyperactivity Disorder (ADHD) is the most commonly diagnosed psychiatric disorder in children, and is becoming a big deal in adults as well. ADHD is a pile of related symptoms, most of them dealing with motivation, impulsivity, inattention, and, you know hyperactivity (they call it ADHD for a reason). Right now, we treat ADHD with stimulants such as Ritalin and Adderall, which in low doses and when they act over a long period of time can increase focus and help people with ADHD function better

DURBAN, South Africa--The roughly 3,000 fossil fuel–fired power plants in North America--Canada, Mexico and the U.S.--emit 6 percent of global greenhouse gases , or nearly as much as all of the European Union. In fact, coal-fired power plants around the globe are the single largest source of greenhouse gas emissions. [More]

DURBAN, South Africa When roughly 25,000 people descend on a city to talk climate change, you can expect at least two things: mountains of waste and copious emissions of the greenhouse gases that they’ve come to talk about so seriously. To offset the hundreds of thousands of tons of these lightweight gases emitted in the pursuit of a global climate treaty, recent such conferences have taken compensatory measures, such as subsidizing retrofits of Bangladeshi brick factories , so that ambassadorial emissions are offset by a reduction in pollution from kilns
