One of the biggest unknowns in understanding the effects of climate change today is the melting rate of glacial ice in Antarctica. Scientists agree rising atmospheric and ocean temperatures could destabilize these ice sheets, but there is uncertainty about how fast they will lose ice.
Global warming may ramp up the flow of methane from groundwater into Arctic lakes, allowing more of the potent greenhouse gas to bubble out into the atmosphere, according to a new study led by researchers at UC Santa Cruz.
An analysis of changes to the climate that occur over several decades suggests that these changes are happening faster than historical levels and are starting to speed up. The Earth is now entering a period of changing climate that will likely be faster than what's occurred naturally over the last thousand years, according to a new paper in Nature Climate Change, committing people to live through and adapt to a warming world.
Trapping carbon dioxide (CO2) emissions from power plants and various industries could play a significant role in reducing greenhouse gas emissions in the future. But current materials that can collect CO2 -- from smokestacks, for example -- have low capacities or require very high temperatures to work. Scientists are making progress toward a more efficient alternative, described in the ACS journal Chemistry of Materials, that could help make carbon capture less energy-intensive.
A recent study simulated a side-by-side comparison of the yields and costs of producing ethanol using miscanthus, switchgrass, and corn stover. The fast-growing energy grass miscanthus was the clear winner. Models predict that miscanthus will have higher yield and profit, particularly when grown in poor-quality soil. It also outperformed corn stover and switchgrass in its ability to reduce greenhouse gas emissions.
Large facilities like big box stores or hospitals could keep the lights on by using a fuel cell that runs off the natural gas that already flows in pipelines below most city streets.
California has experienced more frequent drought years in the last two decades than it has in the past several centuries. That observed uptick is primarily the result of rising temperatures in the region, which have climbed to record highs as a result of climate change, Stanford scientists say.
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time.
A team of scientists lead by Danish geologist Nicolaj Krog Larsen have managed to quantify how the Greenland Ice Sheet reacted to a warm period 8,000-5,000 years ago. Back then temperatures were 2-4 degrees C warmer than present. Their results have just been published in the scientific journal Geology, and are important as we are rapidly closing in on similar temperatures.
The objective of the new cooperation project “MMPSiC” is to significantly enhance the efficiency of power supplies for industrial processes and, hence, to reduce energy consumption and CO2 emission.
