Though still requiring more research and development, direct air capture, a technology that extracts CO2 from ambient air, offers reason for optimism. It is economically viable in several areas and can permit negative emissions to eventually stabilize atmospheric concentrations. While current support for the pioneers in this industry comes from private and philanthropic investment, here are 10 reasons why policy makers should take direct air capture seriously.
While in energy policy discussions, I heard carbon capture, utilization and storage consistently dismissed as either too expensive or too uncertain in a low-carbon future that favors natural gas, energy efficiency and renewable energy. Yet as was made clear during the three-day Research Coordination Network on Carbon Capture, Utilization and Storage annual meeting hosted by the Lenfest Center in April, much can be done, and much more should be done at a much quicker rate than we’re doing it.
Replacing conventional building boilers with electric heat pumps in New York City buildings could substantially increase the viability of renewable energy use in the city, according to a recent study from researchers from the Earth Institute’s Sustainable Engineering Lab.
The end of our fiscal year is just one week away and we need your support more than ever. This year, the generosity of Earth Institute supporters allowed our award-winning scientists and researchers to pursue groundbreaking initiatives in the fields of earth and environmental sciences, ecology, engineering and architecture, law, medicine and public health, economics, political science, public policy, ethics and management, and more to advance global sustainable development.
On June 2, President Obama announced the most significant climate plan in history. The plan, if enacted as stands, seeks to cut carbon emissions on a state-by-state basis, while giving the states almost limitless freedom on how to do so, as long as they adhere to EPA guidelines. Historic it may be, but is it enough to have a real impact on our rapidly changing climate?
Hydraulic fracturing, or fracking, the controversial method for extracting natural gas, has become a hot button issue across the U.S. But let’s try to look objectively at its benefits and risks.
Peter Kelemen, a geologist at Lamont-Doherty Earth Observatory who studies rocks from the deep earth and, recently, their possible uses in battling climate change, has been elected to the National Academy of Sciences.
Carbon capture, storage and reuse has the potential to help us reduce CO2 emissions and combat global warming. The Lenfest Center for Sustainable Energy is bringing together experts from an array of fields to assess the state of the technology April 14-16.
The Earth Institute, Columbia University was proud to support student research in the areas of environment and sustainable development at the annual Student Research Showcase on April 25, 2014. Student interns, research assistants and travel grant recipients, and their Faculty and Research Advisors, were honored for their research contributions that ranged in topics from biodiversity, urban planning, earth sciences to international development.
Among the key findings of the WGII AR5 Report chapter on human security, a topic highlighted in the Report for the first time, is that societies in conflict are more vulnerable to climate change.
