A Dartmouth-led study by more than 50 climate scientists worldwide provides the first clear projection of how carbon emissions may drive the loss of Antarctica's ice sheet over the next 300 years......»»
Microbe dietary preferences found to influence effectiveness of carbon sequestration in deep ocean
The movement of carbon dioxide (CO2) from the surface of the ocean, where it is in active contact with the atmosphere, to the deep ocean, where it can be sequestered away for decades, centuries, or longer, depends on a number of seemingly small proce.....»»
Development strategies for using carbon-based catalysts in CO₂ conversion
One of the primary drivers of climate change, CO2 emissions, has reached over 35 million tons worldwide. With global annual temperatures still rising, reducing CO2 emissions has become a necessity. To turn this necessity into an opportunity, research.....»»
Personal carbon footprint of the rich is vastly underestimated by rich and poor alike, study finds
The personal carbon footprint of the richest people in society is grossly underestimated, both by the rich themselves and by those on middle and lower incomes, no matter which country they come from. At the same time, both the rich and the poor drast.....»»
