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.

Rising CO2 poses significant threat to human nutrition
At the elevated levels of atmospheric CO2 anticipated by around 2050, crops that provide a large share of the global population with most of its dietary zinc and iron will have significantly reduced concentrations of those nutrients, according to a new study led by Harvard School of Public Health.

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.

Model situation?
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have shown that the primary explanation for the reduction in CO2 emissions from power generation that year was that a decrease in the price of natural gas reduced the industry’s reliance on coal.

Of orbits and ice ages
In a paper published in the journal Nature, Harvard Professor of Earth and Planetary Sciences Peter Huybers confirms that changes in the orientation of the Earth’s spin axis have contributed to periods of major deglaciation in the past million years.
