No laughing matter
A recent study shows that nitrous-oxide emissions from thawing Alaskan permafrost are about 12 times higher than previously assumed. About a quarter of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. And, even though researchers are monitoring carbon dioxide and methane, no one seems to be monitoring N2O, the…

Turning tide on greenhouse gases
Emissions from power plants and heavy industry, rather than spewing into the atmosphere, could be captured and chemically transformed from greenhouse gases like carbon dioxide into industrial fuels or chemicals thanks to a system developed by Harvard researchers.

Tackling carbon emissions in China
A Beijing symposium co-sponsored by the Harvard China Project and the Harvard Global Institute explored the possibility of China adopting a carbon tax as a way to reduce climate-warming greenhouse gas emissions. The Gazette spoke with economist Dale Jorgenson, the Samuel W. Morris University Professor, and Chris Nielsen, the executive director of the China Project,…

Concerns about climate change, health
A team of researchers led by James G. Anderson, the Philip S. Weld Professor of Atmospheric Chemistry, warns that a newly discovered connection between climate change and depletion of the ozone layer over the U.S. could allow more damaging ultraviolet (UV) radiation to reach the Earth’s surface, leading to increased incidence of skin cancer.

Carbon counter
Atmospheric scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and Nanjing University have produced the first “bottom-up” estimates of China’s carbon dioxide (CO2) emissions, for 2005 to 2009, and the first statistically rigorous estimates of the uncertainties surrounding China’s CO2 emissions.

Illuminating carbon’s climate effects
Harvard researchers compiled ice and sedimentary core samples collected from dozens of locations around the world, and found evidence that while changes in Earth’s orbit may have touched off a warming trend, increases in CO2 played a far more important role in pushing the planet out of the ice age.

A road map to cleaner energy
A new report by the Harvard Kennedy School’s Belfer Center for Science and International Affairs recommends transforming the U.S. energy picture by nearly doubling funding for U.S. energy technology research and instituting incentives for adopting cleaner technologies, such as a cap-and-trade program for carbon emissions.
