Researchers use 'robomussels' to monitor climate change
October 18, 2016 07:07 AM - Northeastern University
Tiny robots have been helping researchers study how climate change affects biodiversity. Developed by Northeastern University scientist Brian Helmuth, the “robomussels” have the shape, size, and color of actual mussels, with miniature built-in sensors that track temperatures inside the mussel beds.
Modeling Floods That Formed Canyons on Earth and Mars
October 17, 2016 07:05 AM - University of Massachusetts Amherst
Geomorphologists who study Earth’s surface features and the processes that formed them have long been interested in how floods, in particular catastrophic outbursts that occur when a glacial lake ice dam bursts, for example, can change a planet’s surface, not only on Earth but on Mars. Now geoscience researchers Isaac Larsen at the University of Massachusetts Amherst and Michael Lamb at the California Institute of Technology have proposed and tested a new model of canyon-forming floods which suggests that deep canyons can be formed in bedrock by significantly less water than previously thought.
Salty snow could affect air pollution in the Arctic
October 13, 2016 08:03 PM - American Chemical Society
In pictures, the Arctic appears pristine and timeless with its barren lands and icy landscape. In reality, the area is rapidly changing. Scientists are working to understand the chemistry behind these changes to better predict what could happen to the region in the future. One team reports in ACS’ Journal of Physical Chemistry A that sea salt could play a larger role in the formation of local atmospheric pollutants than previously thought.
Wave energy researchers dive deep to advance clean energy source
October 13, 2016 07:25 AM - Sandia National Laboratories
One of the biggest untapped clean energy sources on the planet — wave energy — could one day power millions of homes across the U.S. But more than a century after the first tests of the power of ocean waves, it is still one of the hardest energy sources to capture.
Climate Change Has Doubled Western U.S. Forest Fires
October 11, 2016 06:38 AM - Columbia University Earth Institute
A new study says that human-induced climate change has doubled the area affected by forest fires in the U.S. West over the last 30 years. According to the study, since 1984 heightened temperatures and resulting aridity have caused fires to spread across an additional 16,000 square miles than they otherwise would have—an area larger than the states of Massachusetts and Connecticut combined. The authors warn that further warming will increase fire exponentially in coming decades.
Urban Warming Slows Tree Growth, Photosynthesis
October 6, 2016 07:07 AM - NC State University
New research from North Carolina State University finds that urban warming reduces growth and photosynthesis in city trees. The researchers found that insect pests are part of the problem, but that heat itself plays a more significant role.
The Psychology Behind Climate Change Denial
October 5, 2016 06:53 AM - Uppsala University
Climate change is a serious threat to humans, animals, and the earth’s ecosystems. Nevertheless, effective climate action has been delayed, partly because some still deny that there is a problem. In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem.
In the scientific community there is a strong consensus that humans have significantly affected the climate and that we are facing serious challenges. But there is a lot of misinformation about climate change in circulation, which to a large part is created and distributed by organised campaigns with the aim of postponing measures that could combat climate change. And there are people who are more prone than others to trust this misinformation.
Previous research has consistently shown that it is more common among politically conservative individuals to deny climate change. In her thesis, Kirsti Jylhä has investigated this further and in more detail. Her studies included ideological and personality variables which correlate with political ideology, and tested if those variables also correlate with climate change denial.
Future increase in plant photosynthesis revealed by seasonal carbon dioxide cycle
October 4, 2016 07:11 AM - University of Exeter
Doubling of the carbon dioxide concentration will cause global plant photosynthesis to increase by about one third, according to a paper published in the journal Nature
The study has relevance for the health of the biosphere because photosynthesis provides the primary food-source for animal life, but it also has great relevance for future climate change.
First evidence of deep-sea animals ingesting microplastics
October 3, 2016 07:11 AM - University of Oxford
Following the news that the UK government is to ban plastic microbeads by the end of 2017, a team of scientists led by the University of Oxford has discovered the first evidence of microplastics being ingested by deep-sea animals.
Researchers working on the Royal Research Ship (RRS) James Cook at two sites in the mid-Atlantic and south-west Indian Ocean found plastic microfibres inside creatures including hermit crabs, squat lobsters and sea cucumbers at depths of between 300m and 1800m.
Wetlands and agriculture, not fossil fuels could be causing a global rise in methane
September 30, 2016 07:07 AM - Royal Holloway University of London
Research published today in the American Geophysical Union’s journal Global Biogeochemical Cyclesshows that recent rises in levels of methane in our atmosphere is being driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.
