Crop losses for critical food grains will increase substantially with global warming, as rising temperatures boost the metabolism and population growth of insect pests, new research says. Scott Merrill of the University of Vermont, a co-author of the study published in Science, said: “Climate change will have a negative impact on crops; we are going to see increased pest ...
Low-tech ways of improving soil quality on farms and rangelands worldwide could pull significant amounts of carbon out of the atmosphere and slow the pace of global warming, according to a new UC Berkeley study. The researchers found that well-established agricultural management practices — such as planting cover crops, optimizing grazing, and sowing legumes on ...
Latest research finds plant debris in lake sediment affects the methane greenhouse gas emissions. The flourishing reed beds created by changing climates could threaten to double the already significant methane production of the world’s northern lakes. A new study of chemical reactions that occur when organic matter decomposes in freshwater lakes has revealed that the ...
The collapse of the Thwaites Glacier in West Antarctica could significantly affect global sea levels. It already drains an area roughly the size of Britain or the U.S. state of Florida, accounting for around 4 percent of global sea-level rise — an amount that has doubled since the mid-1990s. As part of a new £20 ...
Scientists conclude methane-producing microbes date back 3.5 billion years, supporting the hypothesis that they could have contributed to early global warming. Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet’s oxygen through photosynthesis. About 3.5 billion years ago, the ...
