Three extreme weather events in the Amazon Basin in the last decade are giving scientists an opportunity to make observations that will allow them to predict the impacts of climate change and deforestation on some of the most important ecological processes and ecosystem services of the Amazon River wetlands.
For the first time in more than a decade, five NASA Earth-observing missions will be launched into space in a single year. To celebrate this milestone, NASA is inviting people all around the world to step outside on Earth Day, April 22, take a "selfie," and share it with the world on social media.
Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere.
After several years of discussions, researchers from Aarhus University (Denmark), Lund University (Sweden) and Stockholm University (Sweden) have determined that nutrients from the land are the main cause of widespread areas of oxygen depletion. The results were published on 31 March in the prestigious American journal Proceedings of the National Academy of Sciences.
Wind turbines placed in the ocean to generate electricity may have another major benefit: weakening hurricanes before the storms make landfall.
A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier.
In the first study of its kind, research undertaken at the University of Southampton has cast significant doubt over the use of biochar to alleviate climate change.
While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. New research in the journal Nature indicates that for each degree that the Earth's temperature rises, the amount of methane entering the atmosphere from microorganisms dwelling in lake sediment and freshwater wetlands — the primary sources of the gas — will increase several times.
Results from a new study co-authored by Netra Chhetri, a faculty member at the Consortium for Science, Policy & Outcomes at Arizona State University, show global warming of only 2 degrees Celsius will be detrimental to three essential food crops in temperate and tropical regions. And beginning in the 2030s, yields from those crops will start to decline significantly.
How can communities dodge future disasters from Mother Nature before she has dealt the blow? Researchers are taking a unique approach to the issue and gaining input and support from community stakeholders. Daniel Murphy, a University of Cincinnati assistant professor of anthropology, will present findings on March 20, at the 74th annual meeting of the Society for Applied Anthropology (SFAA) in Albuquerque, N.M.
