The Politics of Climate Change

The study, in the journal Climatic Change, is one of the first to examine the influence of political orientation on perceived scientific agreement and support for government action to reduce emissions.

Masdar Launches Africa’s Largest Solar PV Plant

Masdar, Abu Dhabi’s renewable energy company, today launched an US$31.99 million utility-scale, 15-megawatt solar photovoltaic (PV) power plant in the Islamic Republic of Mauritania. The Sheikh Zayed Solar Power Plant is located in the capital city of Nouakchott and is the largest solar PV plant in Africa. The new facility accounts for 10 percent of Mauritania’s energy capacity and will displace approximately 21,225 tons of carbon dioxide annually.

CO2 Removal Can Lower Costs of Climate Protection

“Carbon dioxide removal from the atmosphere allows to separate emissions control from the time and location of the actual emissions. This flexibility can be important for climate protection,” says lead-author Elmar Kriegler. “You don’t have to prevent emissions in every factory or truck, but could for instance plant grasses that suck CO2 out of the air to grow – and later get processed in bioenergy plants where the CO2 gets stored underground.”

Reducing Waste of Food: Key Element in Feeding Billions More People

Families can be key players in a revolution needed to feed the world, and could save money by helping to cut food losses now occurring from field to fork to trash bin, an expert said here today. He described that often-invisible waste in food — 4 out of every 10 pounds produced in the United States alone — and the challenges of feeding a global population of 9 billion in a keynote talk at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

Study: ‘Waste heat’ May Reduce Costs for CO2 Capture

Rice University team seeks to optimize CO2 removal from power plant emissions In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using “waste” heat — low-grade steam that cannot be used to produce electricity. The find is significant because capturing CO2 with conventional technology is an energy-intensive process that can consume as much…

Guiding Responsible Geoengineering Research

In an article published March 15 in the journal Science, Edward Parson of UCLA and David Keith of Harvard University outline how the current deadlock on governance of geoengineering research poses real threats to the sound management of climate risk. Their article advances concrete and actionable proposals for allowing further research — but not deployment — and for creating scientific and legal guidance, as well as addressing public concerns.

Amplified Greenhouse Effect Shaping North into South

BU-led international team shows significant reduction in temperature and vegetation seasonality over northern latitudes An international team of 21 authors from 17 institutions in seven countries has just published a study in the journal Natural Climate Change showing that, as the cover of snow and ice in the northern latitudes has diminished in recent years, the temperature over the northern land mass has increased at different rates during the four seasons, causing a reduction in temperature and vegetation seasonality in this area.…

USF and KAUST Chemists Develop Efficient Material for Carbon Capture

Chemists at the University of South Florida and King Abdullah University of Science and Technology have discovered a more efficient, less expensive and reusable material for carbon dioxide (CO2) capture and separation. The breakthrough could have implications for a new generation of clean-air technologies and offers new tools for confronting the world’s challenges in controlling carbon.

Have Shale Plays Hijacked Our Energy Future?

“Ten percent of the Lower 48 has been leased by oil companies. That’s more acreage than we plant in corn and wheat. Oil and gas extraction is now the dominant land use on the continent.   “In short, shale plays are a peculiar sort of blessing. For sure, they’ve given us a staggering amount of new energy. Simultaneously, they’ve hijacked our energy future, chained us to a drilling rig, and thrown away the key.” Source: The Christian Science Monitor Randy…

Cities Can Reduce Greenhouse Gas Emissions by 70 Percent

Kennedy and Sugar make the claim in ‘A low carbon infrastructure plan for Toronto, Canada,’ published in the latest issue of The Canadian Journal of Civil Engineering. The paper aims to show how cities can make a positive difference using realistic, achievable steps. Their research shows that it is technically possible for cities to reduce their greenhouse gas emissions by 70 per cent or more in the long-term.
