A Dissolving Future for Coral Reefs

The latest findings suggest that ocean acidification by carbon dioxide may already be eroding reefs worldwide, and provide a crucial proof for a novel monitoring system tracking erosion on U.S. reefs.

Methane Observation Inspires Action

High-precision and remote-controlled methane and ethane detectors assist scientists in determining methane emission levels from natural gas development in north-central Texas’ Barnett Shale. In October 2013, a pair of scientists took a technologically tripped-out van on a deliberately meandering methane detection mission across north-central Texas. Tara Yacovitch and Scott Herndon of Massachusetts-based Aerodyne Research comprised […]

Cropped image of an emissions report. Growing awareness of the deficiencies of today’s greenhouse gas inventories is inspiring innovation by scientists, policymakers and activists. There is growing hope for “top-down” schemes based on rapid and even real-time measurement of atmospheric greenhouse gases. Now the push is on to install ground and satellite-based instruments.

The goal is to determine carbon’s fluxes through the environment with enough accuracy to pin-point the regions that are carbon sinks and sources. But the plan needs to secure the resources required to address under-observed regions and ecosystems.

Power Potential and Pitfalls on the Congo: Developing Africa’s Cleanest and Largest Hydropower Opportunity

Read his analysis here. NEW DEVELOPMENT: A Reuters news story confirms that the DRC government is pulling out of Westcor in favor of the Billiton-financed project.

South Africa’s Polar-Orbiting Ploughshares – A National Space Agency could help it become a regional powerhouse in Earth observation

Image of SALT stars making circular trails around it. South Africa, having proven its satellite capacity in the design, build out, and launch of SunSat and SumbandilaSat, is preparing to take its space program into higher orbit with the launch of a space agency. Twelve months ago President Kgalema Motlanthe signed legislation to create the South African National Space Agency (SANSA), and nominations for a board were approved in the fall. Its mandate is to promote the peaceful use of space, accelerate the industrial development of space technology, and foster research and international cooperation space science and engineering.

Space-bound in South Africa: A Down-to-Earth Conversation With Dr. Phil Mjwara

Closeup of Dr. Phil MjwaraA month after South Africa succesfully launched it’s second Earth observation satellite, Sumbandila, Earthzine contributor Peter Fairley talks with Dr. Philemon Mjwara, Director General of South Africa’s Department of Science and Technology, about the launch, the benefits South Africa expects to reap from the satellite, and what’s in store for the future of developing countries’ involvement in Earth observation and sustainability.

Sniffing Out Geothermal Energy Resources from the Surface, Sky and Space

Cropped image of Peter Fairley with Didier Sainte Marie, Cofor’s site manager.In Sniffing out Geothermal Energy Resources from the Surface, Sky and Space, energy writer Peter Fairley travels to Paris to do on-the-scene reporting about the progress of geothermal energy in France and elsewhere. Fairley, the editor of the energy web journal Carbon-Nation, shows that geothermal is enjoying a renaissance among experts in many parts of the world as an effective alternative to fossil fuels that also reduces CO2 emissions.

An Earthzine Conversation With Michael H. Freilich

Cropped image of Michael Freilich“It’s almost a golden age of Earth observation because these many missions which are flying at the same time are all measuring different aspects of the system at the same time, and most with global extent. This is giving us, for the first time, the fodder for assembling an integrated view of the Earth.”
