Light pollution is associated with earlier tree budburst across the United Kingdom

The ecological impact of night-time lighting is of concern because of its well-demonstrated effects on animal behaviour. However, the potential of light pollution to change plant phenology and its corresponding knock-on effects on associated herbivores are less clear. Here, we test if artificial lighting can advance the timing of budburst in trees. We took a UK-wide 13 year dataset of spatially referenced budburst data from four deciduous tree species and matched it with both satellite imagery of night-time lighting and average spring temperature. We find that budburst occurs up to 7.5 days earlier in brighter areas, with the relationship being more pronounced for later-budding species. Excluding large urban areas from the analysis showed an even more pronounced advance of budburst, confirming that the urban ‘heat-island’ effect is not the sole cause of earlier urban budburst. Similarly, the advance in budburst across all sites is too large to be explained by increases in temperature alone. This dramatic advance of budburst illustrates the need for further experimental investigation into the impact of artificial night-time lighting on plant phenology and subsequent species interactions. As light pollution is a growing global phenomenon, the findings of this study are likely to be applicable to a wide range of species interactions across the world. Read More

Streamlining Climate Change and Air Pollution Reporting: Final Report

The environmental policies currently being negotiated are likely to require Member State (MS) to control and report their emission of greenhouse gases (GHG) and air pollutants (AP) more precisely. While there are likely to be associated costs, it is also likely that the cost of timely and targeted action will be less than the longer term cost of inaction. A number of European Union (EU) legal instruments are used to regulate emissions – several of these are under review. The review not only needs to anticipate future policy needs but also assess the alignment of the various instruments and whether the burden on users can be further minimized. Read More

Global Warming: Forest Solutions

Tropical deforestation produces more global warming pollution than every car, truck, plane, ship, and train on earth. It’s the largest source of heat-trapping emissions in some developing countries, and it accounts for about 15 percent of the world’s heat-trapping emissions. Reducing deforestation is a practical, cost-effective way to help avert global warming—and it also makes important contributions to saving biodiversity and supporting sustainable development.
