Experts and members of coastal communities possess both differences and similarities in how they perceive the risks associated with changes in sea level. A new study, based on interviews with both, has found that future communication about the risks should focus on specific adaptation and mitigation strategies.

Scientists did not observe changes in plant communities in the coastal dunes of Scotland due to climate change in the past several decades. The region’s proximity to the ocean and its patchy make-up may prevent it from experiencing rapid changes in species distribution.

Olympia oysters (Ostrea lurida) have been shown to adapt to local environments that are as little as 20 km apart, and these adaptations can be passed on to offspring. In this study, oysters that originated from less saline areas tended to be more resilient to extremely low saline conditions than oysters from more saline areas. Since episodes of reduced salinity are a predicted effect of climate change in the San Francisco Bay area under study, the authors say their findings could be useful for future conservation and restoration efforts.

Among the ecological effects of climate change are changes to the timing of natural events, such as flowering. To understand why these phenological changes affect reproduction, this study manipulated conditions in a spring herb to prompt premature flowering. This exposed the flowers to frost, and resulting damage caused dramatic reductions in plant reproduction, suggesting that climate change may threaten plant survival.

Signs that the ranges of sub-mountainous forest plants in France have contracted in response to global warming have been detected in a new study. This pattern is likely to induce a splitting of these species’ ranges across Europe under future climate change, which could have serious consequences for plant genetic diversity and the capacity of plant populations to adapt to warming climates, say the researchers.

Biodiversity scenarios are a useful tool to help policymakers predict how flora and fauna will likely respond to future environmental conditions. Although changes to land use are a major driver of biodiversity loss, scenarios focus overwhelmingly on climate change, a new study shows. The researchers say this imbalance makes scenarios less credible, and make recommendations for developing more plausible projections.

As global temperatures continue to warm, sea-levels are expected to rise, increasing the risk of saltwater inundating wetlands in low-lying coastal areas. A study in Wales, UK, describes how rising sea levels will result in a shift from a wetland rich in plant diversity to one dominated by saltwater and mud in 200 years’ time.

A new approach to modelling the spread of mammal populations under climate change has been developed. The method overcomes the problem of missing ecological data for most species by using information on species characteristics, or ‘traits’, associated with population demographic rates and individual movements to deduce which species move too slowly to escape climate change’s effects on their habitat. The model’s results suggest that around 30% of mammal species may not be able to disperse quickly enough to survive.

Climate change and other environmental changes can have major impacts on plant communities. Researchers have assessed current methods of understanding the impact of these global changes on vegetation and outlined the implications for future research. Vegetation is highly dynamic and likely to respond in complex ways to environmental changes. Researchers should, therefore, use a variety of methods to predict vegetation change in order for findings to be useful for policymaking.

Marine fisheries play a key role in feeding human populations, but are faced with the twin threats of overexploitation and climate change. Using a comprehensive database of global reef-fish communities, a team of researchers has found that the greater the diversity of fish in an assemblage, the less vulnerable that assemblage is to climate change. The researchers suggest climate change mitigation efforts should include a focus on maintaining a wide range of species in at-risk communities.

A new long-term monitoring study is the first to demonstrate that climate changes are having divergent effects on populations of bird species across Europe and the United States. The study identifies broad-scale impacts on the abundance of common bird species over a 30-year period, to show that, overall, populations of bird species across both continents are being affected by changes in climate. The research adds to a growing body of evidence that climate change is affecting biodiversity either positively or adversely, depending on species’ climate preferences.

The effects of climate change on the distribution of species can be predicted more accurately by considering the genetic differences between different groups of the same species, a new study suggests. The researchers found that a computer model which incorporated genetic information on different groups of a US tree species was up to 12 times more accurate in predicting tree locations than a non-genetically informed model.

The impact of ocean acidification — caused by increased carbon dioxide (CO2) emissions dissolving in sea water — on Atlantic cod larvae has been assessed in a new study. The researchers estimate that, under scenarios which might be reached at the end of the century, ocean acidification could double the mortality rate of cod larvae, reducing replenishment of juvenile fish into cod fisheries to 24% of previous recruitment.

Climate change is having mixed — but mostly negative — impacts on ecosystem services, suggest data analysed by a new study. The research, which brings together the findings of over 100 other studies, found that 59% of reported impacts of climate change on ecosystem services are negative, while just 13% are positive. However, the method of research was shown to strongly influence whether impacts are reported as positive or negative, with expert opinion studies far more negative than other types of study.

The influence of light-emitting diodes (LED) on grassland invertebrate communities has been assessed in a recent study. White LEDs increased the total abundance and changed the species of spiders and beetles recorded. Dimming lights and switching lights off during the middle of the night were the best ways of reducing the effects on beetle and spider numbers.

The impacts of climate changes can force animal- and, over a longer time period, plant species to shift their range. Forests in temperate regions, such as north-western Spain, will be increasingly exposed to drought over the next few decades, which is likely to cause geographical changes in their distribution and make-up1. New patterns of plant occupancy or plant extinction have a bottom-up effect on animal species dependent on them, which can significantly impact on isolated or endangered populations of animals. This study sought to assess the potential impact of climate change on the brown-bear (Ursus arctos) population in the Cantabrian Mountains.

The warmer, drier conditions expected under on-going climate change will reduce the rates at which soil fauna and microbes decompose plant litter, suggests new research from Germany. This may have important implications for agriculture and natural ecosystems worldwide, as litter decomposition is a key process in cycling and distributing nutrients throughout ecosystems.

Considering the impact on soil carbon, biodiversity and ecotoxicity is important when assessing the environmental footprint of dairy products, suggests a new study, which explored the impacts of organic and conventional milk production in three types of system established in Western Europe. The study found that organic milk production had a significantly lower impact on ecotoxicity and biodiversity than conventional milk production, and suggests that including soil carbon changes in the assessment would result in greater reductions in the carbon footprint of organic, rather than conventional, milk — in some cases by up to 18%.

According to new research, there was no substantial change from 2000 to 2009 in the global use of the insecticide DDT to control diseases such as malaria. Pyrethroids, another type of insecticide, are also widely used, but there are concerns that insects are developing resistance and insecticidal nets containing pyrethroids are becoming less effective.

Different management practices using pesticides affect the diversity, number and ecological traits of ground spiders in apple orchards, a new study finds. Because spiders are viewed as good indicators of the quality of an entire ecosystem, the results reveal that organic orchard management may be better for local management and landscape characteristics when compared to those with pesticide use.

Oestrogens are ‘female’ hormones that can enter the aquatic environment after excretion by humans and animals, causing ‘feminisation’ of male fish. This study carried out a risk assessment for oestrogen-like endocrine disruption in the UK in the 2050s, based on likely changes to the human population, river flows and temperature. The authors found that risk is likely to increase under future conditions and recommend further research to assess whether improving sewage treatment could reduce oestrogen pollution.

Researchers have shown that in the Baltic Sea the abundance of common fish species, used as an indicator of ecosystem health, is influenced by climate-related oceanic conditions at a local scale, such as sea temperature. The researchers suggest, therefore, that the environmental status of coastal fish communities in the region should be assessed and managed at a local scale.

Rare earth elements (REE) are used to make many low-carbon technologies, including electric vehicles and wind turbines. Mining and processing of REE, which mostly takes place in China, has a reputation for causing environmental damage. A new study presents a method for evaluating the environmental impacts of REE production based on life-cycle assessment (LCA: a way of determining a product's overall impact during some or all of its journey from extraction to end-of-life). The researchers applied the method to a prospective REE mine in Malawi, south-east Africa, to reveal the most environmentally impactful stages of production, and the greenest source of energy.

If the effects of air pollution on climate change are included in air quality strategies, efficiency gains of €2.5 billion can be achieved in the EU, according to recent research.

New research suggests potential benefits in integrating air quality and climate change policy. It predicts that accounting for the climate impact of certain air pollutants in the EU, USA and China could complement policies designed to reduce the air quality impacts of these pollutants.

A new study has assessed the potential of several “fast-action” climate change mitigation strategies. Key options are reducing use of hydrofluorocarbons (HFCs), reducing emissions of black carbon and ozone-forming pollutants, and sequestering carbon through afforestation and biochar production.

Climate change is likely to significantly affect future air quality over Europe. According to a recent European study, climate change alone is likely to significantly increase ozone pollution in Europe and by as much as 50 µg.m-3 (micrograms per cubic metre) over central France in July by the year 2100, compared with 1990 levels.

A study by Swedish scientists provides new insights into how climate change could affect future ozone concentrations in European countries. The findings of this study suggest that average ozone concentrations will increase more in Southern Europe than in more Northern and mountainous regions under the influence of climate change in the 21st century.

Combining policies that tackle local air pollution and global climate change will deliver enhanced benefits for climate change mitigation, according to researchers. Medium-term efforts to control air pollution will provide additional benefits to long-term strategies that aim to curb climate change.

Implementation of technology to clean the flue gases of coal-fired power plants has significantly reduced sulphur and fine particle emissions that cause environmental damage. However, recent research suggests that plants applying this technology would emit more ultrafine particles (1-10 nanometer (nm) diameter) that affect the formation of clouds, with the unintended consequence of changing the amount and intensity of rainfall downwind of fossil fuel power installations.

The Earth is now absorbing more energy from the Sun than it is radiating into space. A recent analysis indicates that most models of this energy imbalance underestimate the impacts of human-made aerosols and overestimate time lags in response to the climate. As such, the energy imbalance and future impacts on climate may be greater than predicted.

Low emission zones (LEZs), which restrict access for high emission vehicles, have proven to be a successful way to improve air quality in line with EU regulations. An analysis of London’s LEZ has revealed discernible reductions in air pollution levels five years after implementation.

Climate change affects air pollution at a regional and local scale. A recent study has reassessed the latest findings and suggests that climate change will increase ozone concentrations by about 3 parts per billion (ppb) in central and western Europe in the year 2050 if emissions from human activities remain at present-day levels. However, if emissions increase, ozone concentrations could increase by 16 ppb for much of Europe.

Globally co-ordinated climate change policy to limit warming to 2°C could provide additional health, ecological and economic benefits. Using established methods, researchers estimated that the implementation of climate policy would also reduce global expenditures on air pollution control in 2050 by €250 billion.

Greater amounts of air pollutants emitted in East Asia will move around the globe under climate change, a recent study predicts. Changes to wind speeds and air pressure will mean that movement of pollution from this region is enhanced under a changing climate. These results highlight the need for globally coordinated efforts to tackle air pollution and climate change.

Effective greenhouse gas (GHG) mitigation measures to stabilise global temperature change to no more than 2°C above pre-industrial temperatures would also substantially reduce air pollutant emissions, recent research predicts. A variety of mitigation options are available, including switching from fossil fuels to renewable sources of energy. To achieve the necessary GHG emission reductions, one key option is to impose carbon taxes. However, these would need to be high to help achieve this target, according to the study’s authors.

The health risks associated with climate-induced changes to indoor environments are explored in a new study. UK-based researchers synthesised findings of how climate change — and mitigation and adaptation measures — might affect the inside of buildings, through overheating, air quality, allergies and infections, flood risk and other exposure risks.

Pollutants emitted by human activities have caused declines in air quality and drastic changes to climate. Despite being inextricably linked, these two major environmental issues tend to be viewed separately by policy. However, in certain instances, considering these issues together could lead to strategies that benefit both, according to a newly published review.

Nitrification inhibitors are thought to mitigate climate change by reducing emissions of nitrous oxide — a potent greenhouse gas — from land. However, they may not be as effective as once thought, a new study suggests. The researchers found that, while inhibitors decrease emissions of nitrous oxide, they can increase emissions of ammonia — which is later converted to nitrous oxide. They recommend these effects are considered when evaluating inhibitors as a mitigation technology.

It is increasingly evident that human health is closely linked to the environment, and to biodiversity. A study commissioned by the European Commission summarises the many and varied ways in which disturbances to biodiversity affect the spread of human diseases.
