Researchers at Winrock International have developed a first-of-its-kind method for estimating carbon emissions from forest degradation caused by selective logging in tropical regions. Refined over a period of 15 years and tested in six countries, the approach is highlighted in an article authored by Winrock’s Ecosystems Services experts, Timothy Pearson, Sandra Brown and Felipe Casarim — published April 1 in Environmental Research Letters. Until now, efforts for reducing emissions from...

The extreme cold weather observed across Europe and the east coast of the US in recent winters could be partly down to natural, long-term variations in sea surface temperatures, according to a new study published today. Researchers from the University of California Irvine have shown that a phenomenon known as the Atlantic Multidecadal Oscillation (AMO)—a natural pattern of variation in North Atlantic sea surface temperatures that switches between a positive and negative phase every 60-70...

As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions. The new study, published today, 18 February, in IOP Publishing's journal Environmental Research Letters, has highlighted the risks of...

The intensity of tropical cyclones hitting East Asia has significantly increased over the past 30 years, according to a new study published today. The coastlines of China, Korea and Japan in particular have experienced increasingly stronger cyclones, which the researchers have attributed to increasing sea surface temperatures and a change in atmospheric circulation patterns over the coastal seas. According to the study, the changes in sea surface temperature and wind flows meant that...

More frequent harvest could substantially boost global food production on existing agricultural lands Harvesting existing cropland more frequently could substantially increase global food production without clearing more land for agriculture, according to a new study from the Institute on the Environment (IonE) at the University of Minnesota. The study, published in Environmental Research Letters, tracked global harvest trends of 177 crops between 1961 and 2011. It found that the total...

Expanding millions of hectares of Brazilian land to produce palm oil for food or for renewable, clean-burning biodiesel could result in extremely high emissions of carbon dioxide (CO2) unless strict controls are put in place. This is according to a new study published today, 14 November, in IOP Publishing's journal Environmental Research Letters, by a group of researchers from the University of California, Davis. The researchers found that unless the oil palm plantations are strictly...

Our current pledges to reduce greenhouse gas emissions, which are projected to set the global mean temperature increase at around 3.5°C above pre-industrial levels, will expose 668 million people worldwide to new or aggravated water scarcity. This is according to a new study published today, 13 September, in IOP Publishing's journal Environmental Research Letters, which has calculated that a further 11 per cent of the world's population, taken from the year 2000, will live in water-scarce...

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target. This is according to a new study, published today, 11 July, in IOP Publishing's journal Environmental Research Letters, which shows that ambitious temperature targets can be exceeded then reclaimed by implementing BECCS around mid-century....

People think of wind as an energy source with few limits, offering an unending power source with distinct capacity advantages over sources that deplete, such as fossil fuel. Yet, new research in mesoscale atmospheric modeling by UNC Charlotte's Amanda S. Adams and Harvard University's David W. Keith, published Monday in the journal Environmental Research Letters, suggests that the power capacity of large-scale wind farms may have been significantly overestimated. With large-scale wind...

A child can directly influence the attitude and behaviour of their parents towards the environment without them even knowing it. This is according to a group at Imperial College London who have, for the first time, provided quantitative support for the suggestion that environmental education can be transferred between generations and that it can actually affect behaviour. Their findings have been published today, 13 February, in IOP Publishing's journal Environmental Research Letters....


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
