Lower shipping emissions may lead to higher global temperatures
Products that we depend on and use every day arrive by way of massive container ships to ports around the world. But the maritime shipping industry is also responsible for polluting the air and oceans with sulfur dioxide, which can negatively affect.....»»
Researchers use training model to map planted and natural forests via satellite image
While planting trees may seem like an easy win to combat climate change, planted forests often encroach on natural forests, wetlands, and grasslands. This can reduce biodiversity, disturb the natural environment, and disrupt carbon and water cycling......»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
Trees in tropical logged forests release carbon at greater rate despite faster growth, study finds
Tree stems in tropical forests recovering from logging produce carbon dioxide at a greater rate than those in unlogged forests, according to a new study from the University of Leicester......»»
Deep underground flooding beneath hot springs: A potential trigger for the 1995 Kobe earthquake
Researchers at University of Tsukuba have shown that the 1995 Kobe (Hyogo-ken Nanbu) earthquake, which struck southern Hyogo Prefecture, may have been triggered by deep underground flooding beneath Arima Hot Springs. By analyzing the stable isotope r.....»»

Enzyme-inspired catalyst puts chemicals in right position to make ethers
Taking inspiration from enzymes, chemists at the University of Illinois Urbana-Champaign developed a catalyst to simplify the synthesis of ethers, key functional components of many drugs, foods, personal care items and other consumer goods. The catal.....»»
Rapid loss of Antarctic ice after 2100 likely under current emissions, climate scientists find
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.....»»
Catalyzing environmental cleanup: A highly active and selective molecular catalyst and electrified membrane
Some chemicals create environmental problems; others, fortunately, can help clean them up. Chemists from Yale University and their colleagues have developed an electrochemical catalyst and membrane that offers an efficient and sustainable way to trea.....»»
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.....»»
Ozone pollution reduces yearly tropical forest growth by 5.1%, study finds
Ozone gas is reducing the growth of tropical forests—leaving an estimated 290 million tonnes of carbon uncaptured each year, new research shows......»»
