The most powerful El Niños – such as the ones that developed in 1982-83 and 1997-98 – are forecast to occur once every 10 years throughout the rest of this century, according to study lead author Wenju Cai of the Commonwealth Scientific and Industrial Research Organisation, Australia’s national science agency. Over the past 100 years or so, however these “extreme” El Niños occurred only once…

The study, published online January 15, 2014, in the journal Ecology Letters, examined competitive dynamics among crustose coralline algae, a group of species living in the waters around Tatoosh Island, Washington. These species of algae grow skeletons made of calcium carbonate, much like other shelled organisms such as mussels and oysters. As the ocean absorbs more carbon dioxide from the atmosphere, the water becomes more…

The scientists report in Nature Climate Change that they worked their way through more than 1.2 million distribution records of 25 species of British butterfly at intervals over the past 40 years. Britain has a long history of systematic bird and butterfly observation and much information had been recorded by enthusiastic amateur natural historians, and the partners in the study were agencies such as Butterfly…

The team has also said that creatures living in the remotest regions of the ocean will also be affected by changes in the environment. Decrease in the number of marine organisms will directly hit fisheries, researchers added. For the study, the team used latest climate models to understand the changes in food supply in the future. They then looked at the relationship between food supply…

Many of the world’s great cities are on low-lying coastal plains, or on river estuaries, and are therefore anyway at risk as sea levels rise because of global warming. But human action too – by damming rivers, by extracting ground water and by building massive structures on sedimentary soils – has accelerated coastal subsidence. Add to this the possibility of more intense tropical cyclones as…

And if the world reacts, stops burning fossil fuel, and invests in green energy, then your chances of being killed by a wind turbine become just so much higher. Holger Goerlitz, of the Max Planck Institute for Ornithology in Seewiesen, Germany, and colleagues report in the Proceedings of the Royal Society Interface that they looked at the challenge faced by bats that hunt with ultrasound…

The team's work, which has been supported through funding from the Natural Environment Research Council (NERC), is published by leading international journal Global Change Biology today (Friday, October 18), in a paper entitled 'Multi-decadal range changes versus thermal adaptation for north east Atlantic oceanic copepods in the face of climate change'. The paper's lead author Stephanie Hinder, a PhD student in Swansea University's Department of…
