For decades, hydroelectric dams served as the United States’ top source of renewable energy. But last year, wind power took the top spot, according to a new report by the American Wind Energy Association, an industry trade group. It is now the fourth largest source of energy in the U.S., behind natural gas, coal, and nuclear.
Bacteria in certain microbiomes appear to help corals adapt to higher water temperatures and protect against bleaching, as shown by a KAUST-led research team.
Despite a slow down in the number of new natural gas wells in the Marcellus Shale region of Northeast Pennsylvania, new research led by Drexel University finds that atmospheric methane levels in the area are still increasing. Measurements of methane and other air pollutants taken three years apart in the rural areas of Pennsylvania that have been the target of natural gas development over the last decade, revealed a substantial increase from 2012 to 2015.
A recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester sheds light on the interactions of gas hydrates and climate.
The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature performed by the U.S. Geological Survey and the University of Rochester.
Methane hydrate, which is also referred to as gas hydrate, is a naturally-occurring, ice-like form of methane and water that is stable within a narrow range of pressure and temperature conditions. These conditions are mostly found in undersea sediments at water depths greater than 1000 to 1650 ft and in and beneath permafrost (permanently frozen ground) at high latitudes. Methane hydrates are distinct from conventional natural gas, shale gas, and coalbed methane reservoirs and are not currently exploited for energy production, either in the United States or the rest of the world.
A team of researchers, led by the University of Minnesota, has invented a new technology to produce automobile tires from trees and grasses in a process that could shift the tire production industry toward using renewable resources found right in our backyards.
Conventional car tires are viewed as environmentally unfriendly because they are predominately made from fossil fuels. The car tires produced from biomass that includes trees and grasses would be identical to existing car tires with the same chemical makeup, color, shape, and performance.
New research by academics at the University of East Anglia (UEA), University of Kent and University of Lincoln, suggests that insights from behavioural science can help inform the design of road signs to bring about changes in driver behaviour.
Research in behavioural science has demonstrated how even very minimal cues or ‘nudges’ can sometimes have a powerful influence on human behaviour and decision-making. In this study, the researchers applied this approach to examine whether simple visual and written cues could be used to encourage drivers to switch off their engines while waiting at railway crossings.
For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published by a team of ocean scientists and statisticians, including Rutgers professors Benjamin Horton and Robert Kopp and Rutgers Ph.D. student Erica Ashe. That’s because those fluctuations occurred without the assistance of human-influenced climate change.
In a paper published in Nature Communications, Horton, Kopp, Ashe, lead author Aron Meltzner and others report that the relative sea level around Belitung Island in Indonesia rose twice just under 2 feet in the period from 6,850 years ago to 6,500 years ago. That this oscillation took place without any human-assisted climate change suggests to Kopp, Horton and their co-authors that such a change in sea level could happen again now, on top of the rise in sea level that is already projected to result from climate change. This could be catastrophic for people living so close to the sea.
NASA-NOAA's Suomi NPP satellite captured a night-time image of Tropical Cyclone Carlos using infrared light that showed the storm was being stretched out. Carlos is being adversely affected by the Westerlies.
Pregnancy in the UK has never been safer, say scientists from King's College London writing in the latest edition of The Lancet.
The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the Arctic Ocean has risen 20-fold. This was recently reported in a study by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).
