Salt Lake's light rail trains are air quality sleuths The TRAX project is the only known transit-based mobile air quality network in North America. Some results are unsurprising, such as spikes of carbon dioxide and nitrogen dioxide, byproducts of gasoline combustion, at street intersections. But the sensors
World's most efficient production of succinate from carbon dioxide Succinate is widely used as a raw ingredient for petrochemicals, and there is high demand for a way of producing succinate that is renewable and environmentally benign. A Japanese researcher has discovered that succinate production levels increase when cy

He says the colorful metal, known as bismuth, could help reduce rising carbon dioxide levels in the atmosphere and pro
Climate change forced zombie ant fungi to adapt Zombie ants clamp on to aerial vegetation and hang for months spewing the spores of their parasitic fungi, but researchers noticed that they do not always clamp on to the same part of the plant. Now the researchers know that the choice of leaves or twigs
China floods to hit US economy: Climate effects through trade chains Fluvial floods will increase due to human-made climate change, in particular in China. This might raise direct and indirect economic losses along the global supply and trade chains. The US is susceptible to indirect climate-related economic losses due to

Satellite study finds major shifts in global freshwater A new global, satellite-based study of Earth's freshwater found that Earth's wet areas are getting wetter, while dry areas are getting drier. The data suggest this pattern is due to many factors, including human water management practices, human-caused cl
Climate change should help Midwest corn production through 2050 Contrary to previous analyses, research published by Michigan State University shows that projected changes in temperature and humidity will not lead to greater water use in corn. This means that while changes in temperatures and humidity trend as they ha
Antarctic seals can help predict ice sheet melt Two species of seal found in Antarctic seas are helping scientists collect data about the temperature and salinity of waters around vulnerable ice sheets in West Antarctica. Understanding more about how this water gets towards the ice shelves by measuring
How far to go for satellite cloud image forecasting into operation Simulated satellite cloud images not only have the visualization of cloud imagery, but also can reflect more information about the model. Using the atmospheric radiation transfer model and high-resolution numerical weather forecast results, researchers fr
Cassava breeding hasn't improved photosynthesis or yield potential University of Illinois researchers analyzed four African cultivars to find out how breeding has impacted photosynthesis -- the process that transforms light energy and carbon dioxide into yield. They found that unimproved landraces of cassava - cultivars
Big mamma fish give proportionally bigger reproductive outputs Even accounting for their proportionate size, bigger female fish produce many more offspring than smaller fish, a new study reveals. The results hold implications for fisheries managers, since climate change is expected to reduce the size of fish (and thu
Geoscientists suggest 'snowball Earth' resulted from plate tectonics About 700 million years ago, the Earth experienced unusual episodes of global cooling that geologists refer to as 'Snowball Earth.' In a new study published in the April issue of the journal Terra Nova, two geologists at The University of Texas at Dallas

Global tourism carbon footprint quantified in world first The world's tourism footprint has been quantified across the supply chain, with the carbon-intensive industry revealed as a significant and growing contributor to greenhouse gas (GHG) emissions. Small islands attract a disproportionate share of GHG emissi
New study finds climate change threatens Marine Protected Areas New research from the University of North Carolina at Chapel Hill and collaborators found that most marine life in Marine Protected Areas will not be able to tolerate warming ocean temperatures caused by greenhouse gas emissions. The study found that with
Greenhouse gas 'feedback loop' discovered in freshwater lakes Latest research finds plant debris in lake sediment affects methane emissions. The flourishing reed beds created by changing climates could threaten to double the already significant methane production of the world's northern lakes.
Odd microbial partnerships via electrically conductive particles Human activities have contributed to global warming subsequently leading to increasing erosion of land. This results in conductive minerals being washed increasingly into water streams. The inflow of conductive particles can enable unusual electric partne
Are emperor penguins eating enough? For emperor penguins waddling around a warming Antarctic, diminishing sea ice means less fish to eat. How the diets of these tuxedoed birds will hold up in the face of climate change is a big question scientists are grappling with.
American pikas tolerate climate change better than expected The American pika, a relative of rabbits, occupies rocky environments in the mountains of western Northern America. It has been widely thought that pikas could not survive extremes of temperature and thus were at risk of running out of space at the tops o
Scientists project a drier Amazon and wetter Indonesia in the future Climate models predict that an increase in greenhouse gases will dry out the Amazon rainforest in the future while causing wetter conditions in the woodlands of Africa and Indonesia. Researchers at the University of California, Irvine, and other instituti
New catalyst turns ammonia into an innovative clean fuel Ammonia (NH3) has attracted attention in recent years as a carbon-free fuel that does not emit carbon dioxide. For use as a fuel, it should have a lower combustion temperature and produce only nitrogen (N2) and water. Now, Japanese researchers have succee
NUS geography researchers determine benefits of Singapore's mangroves A three-year study conducted by researchers from the National University of Singapore has identified that apart from cultural benefits, mangroves act as nursery habitat for fish and as coastal defence, as well as storing carbon that could help offset some
New study addresses the role of health in climate lawsuits Researchers at the George Washington University (GW) are at the forefront of analyzing how climate lawsuits shape the nation's response to climate change. A new analysis investigates the role of health concerns in climate litigation since 1990 and finds
No future for egoists -- that's what their brain says! Some people are worried about the consequences of climate change, while others consider them too remote to have an impact on their well-being. UNIGE Researchers examined how these differences are reflected in our brains. With the help of neuro-imaging, th
Blinded by the light: Climate change, the sun, and Lake Superior Lakes tend to emit carbon dioxide (CO2) to the atmosphere, making them important players in the planet's natural regulation of its climate. However, the direction of the flow of CO2 between lakes and the atmosphere can be influenced by humans or by natura
