Climate change: Jet fuel from waste ‘dramatically lowers’ emissions

Getty ImagesA new approach to making jet fuel from food waste has the potential to massively reduce carbon emissions from flying, scientists say.Currently, most of the food scraps that are used for energy around the world are converted into methane gas.But researchers in the US have found a way of turning this waste into a type of paraffin that works in jet engines.The authors of the new study say the fuel cuts greenhouse gas emissions by 165% compared to fossil energy.This figure comes from the reduction in carbon emitted from airplanes plus the emissions that are avoided when food waste is diverted from landfill.Six questions about the Cumbria coal controversy'Right to repair' law to come in this summerClimate threats to historic sites identifiedThe aviation industry worldwide is facing ...
Melting glaciers may speed carbon emissions, fuel climate feedback loop

Melting glaciers may speed carbon emissions, fuel climate feedback loop

Science
March 15 (UPI) -- While some of the consequences of climate change have a balancing effect, working to slow warming patterns, many more seem to fuel feedback loops that accelerate warming. Now, an international team of scientists led by researchers at the University of Leeds has found another. According to their analysis, the loss of alpine glaciers has made mountain rivers friendlier to fungi, accelerating plant decomposition and carbon emissions. Advertisement Researchers described the feedback loop in a new paper, published Monday in the journal Nature Climate Change. With alpine glaciers the smallest they've been in thousands of years, mountain rivers are getting warmer. They've also become less prone to water flow variability and sediment movement, allowing fungi to flourish. When f...
