Climate and land use change to affect malaria spread in tropical Africa

A recent study has projected changes in the spread of malaria caused by climate change and climate variability in Africa by including the effect of variations in land use on local climate. It concludes that the risk of malaria epidemics is likely to shift from the north to the south of the Sahel, and to highland areas previously free of the disease.

Crop yields largely unharmed in geoengineered climate

Concerns about the negative impacts of ‘sunshade’ geoengineering on global food security are not supported by a recent modelling study, the first to simulate yield changes in a geoengineered climate. However, to mitigate climate change, the researchers suggest actions to reduce CO2 emissions are safer than introducing geoengineering projects, partly because some regions may actually suffer reduced crop yield in a geoengineered climate.

Climate warming may enhance polar cod survival

Researchers have demonstrated that hatching in polar cod can begin as early as January in Arctic seas that receive large freshwater input, compared to April-July in seas with little freshwater input. Since early hatching leads to higher survival rates, the effects of climate change may enhance polar cod’s survival by favouring conditions that allow winter hatching to occur.




climate

Arctic methane ‘leak’ could cause abrupt climate warming

For thousands of years, vast amounts of methane – a potent greenhouse gas – have been stored in frozen deposits on land and under the ocean in the Arctic. A new study has found that rapidly rising temperatures are accelerating the release of methane by thawing subsea ‘permafrost’, releasing nearly 8 million tonnes into the atmosphere each year and potentially increasing global warming.

Changes in species interaction provide clues to climate change extinctions

How does climate change cause extinction? An extensive analysis of the available evidence has explored this question and concluded that climate change’s effects on the interactions between species is likely to be the main reason for local extinctions. For example, climate change may lead to the loss of prey for predators.




climate

Interactions between species affect their response to climate change

Shifts in species’ ranges are expected under climate change, as organisms move to find suitable conditions. New research in the Mediterranean Sea has found that the way species interact could also have a significant effect on their resilience in a changing climate.

The uncertain health impacts of climate change

A new study assesses the potential impacts of climate change on human health in the Netherlands. The researchers conducted a survey, asking health experts to rate the level of uncertainty attached to different health impacts of climate change, which highlighted heat-related deaths and vector-borne diseases as particularly relevant to climate change adaptation.




climate

Significant economic effects of climate change on European timber industry

The impact of climate change on the distribution of tree species is likely to have economic implications for the timber industry. A new study has estimated that climate-induced shifts in range could reduce the value of European forest land for the timber industry by between 14 and 50% by 2100. At the higher end of this estimate, this could equate to a potential loss of several hundred billions of euros.




climate

Policy timing is the most influential aspect in reaching climate change target

The social, political, technological and geophysical factors that affect the control of climate change have been assessed in a recent study. The results suggest that political factors, in terms of delaying the implementation of mitigation strategies, have the biggest effect on limiting global warming to below 2C.




climate

‘Building with Nature’ increases resilience to climate change

New ecosystem-based solutions which provide flexible resilience to coastal flooding, rather than rigid defences, are needed in the face of global environmental change. A recent study examines a new coastal protection scheme in the Netherlands which reduces ecosystem damage whilst offering resilient defence against flooding. Using this case study, the researchers present a framework for evaluating climate change adaptation measures called ‘Building with Nature’.

Climate change and pollution threaten fishing catches

Warming of coastal areas due to climate change is already having an important impact on fishing catches in the North Atlantic, according to a new study. The study also suggests that rising levels of nitrogen pollution, due to run-off from farming and sewage disposal, will pose a serious threat to fisheries in the near future if left unchecked.




climate

Harmful algal blooms in Europe will increase under climate change

Harmful algal blooms may become more common in north western European waters as a result of climate change, according to a new study. The researchers predicted that by the end of this century blooms of two groups of algal species will occur over larger areas and for longer periods every year.




climate

Climate change to shift global spread and quality of agricultural land

New areas of land suitable for agriculture will open up under climate change’s effects, new research predicts, particularly in far northern regions of the world. However, the overall quality of land for farming will decline and many regions, including Europe, could lose large areas of suitable land.

Environmental Scenario Planning: what if marine conservation hotspots in NE Atlantic increase under climate change?

Marine biodiversity conservation in the north-east Atlantic needs a combination of more adaptable management strategies and international co-operation, a new study says. This is required to deal with a potential increase in marine conservation hotspots under climate change.




climate

Compost and climate change: a novel mitigation strategy?

Native soils are thought to take up more of the greenhouse gas methane than land used for farming. This study shows that, while agriculture can exert an adverse impact on soil methane uptake, the application of soil conditioners like compost may compensate for loss of the methane sink function. The researchers propose new land management strategies based on this finding

Climate-friendly meal options positively received by restaurant customers

Restaurants can influence consumer food choices by offering climate-friendly meals on their menus, a recent study concludes. In a trial at Finnish restaurants, customers and staff were receptive to selecting meals based on the carbon footprints of their ingredients. Appearance, taste and healthiness were priority factors in consumers’ choices. The research highlights the importance of planning communication strategies and the need for a carbon footprint food database.

Loss of soil carbon linked to climate change in England and Wales

Soil and plants store around 5% of the world’s carbon, but carbon storage in some soils is in decline. Recent research has found that climate change accounted for 9–22% of carbon declines in organic soils in semi-natural habitats throughout England and Wales from 1978–2003. The researchers say monitoring soils rich in carbon should be a priority to ensure that more carbon is not released to reinforce climate change.

Risk of steep glacier collapse in the Alps will considerably increase due to climate warming

Glaciers are sensitive indicators of climate change. This study focused on hanging glaciers in the French Alps, where warming is increasing the risk of glaciers collapsing. The authors applied a state-of-the-art numerical model to a particularly hazardous glacier in Mont Blanc to simulate how it will respond to climate change. The results suggest the glacier may become unstable in the current century, posing a risk to the inhabitants of the valley below.

Framing issues locally can be persuasive in climate change communication

Messages that focus on the local impacts of climate change are among the most effective at reaching people who are generally dismissive of climate science, according a recent survey of Australian residents. The questionnaire asked participants about their attitudes and beliefs about climate change. Participants were shown a range of messages related to climate change adaptation, and then asked how much each message motivated them to take action. Presentations that contained local impacts, specific advice and negative emotive content were found to be the most effective.

Ignoring flood risks leads to increasing losses: assessment should include climate change, land use and economic development

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.




climate

Environmental hazards due to climate change set to increase in Europe — with regional differences

Researchers have modelled the exposure to multiple hazards across different regions of Europe in relation to heat, cold, drought, wildfire, flooding and wind. The study indicated that, over the next century, environmental hazards are likely to increase, particularly along coastlines and on floodplains, and that south-western Europe is likely to be the worst-hit region.

Renewable-energy technologies can help meet the increased cooling demand in cities due to climate change

The available and emerging renewable technologies suitable for urban environments have been assessed in a recent study. Wind and solar technology can now be integrated into building design, and smart grids and metering can more efficiently manage energy production and demand at a local level. Investing in community-level renewable-energy projects can, therefore, help meet the future energy needs of towns and cities.

New insights into multi-century phytoplankton decline in North Atlantic predict further decline under climate change

Phytoplankton are essential to marine food webs and fisheries. However, a new study indicates that their levels have declined in the North Atlantic since the beginning of the 19th century. This coincides with weakening ocean-circulation patterns, partly caused by melting ice caps. If the melting continues, the study warns of a dramatic fall in North Atlantic plankton levels that could have cascading effects across marine food webs, reducing the ocean’s ability to absorb carbon and threatening the supply of seafood for humans.

Carbon dioxide successfully stored in volcanic rock — could help mitigate climate change

Storing atmospheric carbon dioxide (CO2) has the potential to mitigate the impacts of changes in climate. Researchers have now developed a way to inject CO2 into volcanic rock, and tested it in Iceland. Over 95% of the injected CO2 was mineralised (converted into a solid) within two years, instead of taking centuries or millennia as previously anticipated. The technique demonstrates potential for the permanent and safe storage of CO2 within basaltic rocks.

Climate adaptation: Can vulnerable countries cope with the costs of extreme weather?

Following extreme weather events, many countries are unable to afford the costs of providing relief to communities and repairing infrastructure, a new study suggests. The researchers estimate that providing relief on a global scale for events which recur every 10 to 50 years would cost US$3.3 billion (€2.37 billion) annually.

How policies could help winegrowers adapt to climate change

Grapes are sensitive to small changes in temperature, rain and sunlight, meaning climate change will have implications for wine producers worldwide. This study assessed local vulnerabilities and adaptation strategies in two wine-producing areas in France. The findings may help growers to develop suitable methods of adapting to long-term climate change.

The economic impact of climate change on European agriculture

A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered. Farms in southern Europe are particularly sensitive to climate change and could suffer value losses of up to 9% per 1 °C rise. The researchers say policy, on water and land use, for example, will be crucial to help farmers adapt to climate change and mitigate economic losses.

Diesel cars’ climate impacts not as beneficial as believed, scientists conclude

The promotion of diesel-fuelled cars in Europe may not have had the beneficial environmental effects that were expected, research suggests. It has been assumed that they help reduce greenhouse gas (GHG) emissions from the transport sector, but studies show that their fuel efficiency is lower than previously believed, while their black carbon and nitrogen oxides emissions are higher. The consequent reduction in global warming effects from diesel cars may therefore be negligible, perhaps even negative.

Climate change and transport: effects of sea-level rise on an English railway line

Climate change will have major consequences for transport networks, especially those located on coastlines. This study assessed the impact of projected sea-level rise on a vulnerable stretch of railway line on the coast of South West England. The authors say their semi-empirical modelling method could provide guidance to policymakers worldwide.

Fire patterns in Spain under a changing climate

A recent study has found that fire regimes have changed in Spain over the past 42 years. The pattern of changes has affected the number of fires and burned area, reflecting a changing climate and environmental conditions, such as land use changes caused by a population shift from rural to urban areas, and modern fire suppression activities.

Knowledge alone is ‘not enough’ to prepare for future climate risks: the case of Swedish forestry

Understanding the social context of Swedish forestry is key to understanding how the sector could be persuaded to move beyond ‘business-as-usual’ practices, to prepare for future climate risks, argues a new study. Using an approach that provides insights for future behavioural change more widely, the researchers explore the influences on forest managers’ behaviour, and highlight certification schemes as one important driver of actions which make forests better adapted to climate change. Knowledge on climate change risks and actions in itself is not enough to change behaviour, the study finds. For many environmentalists it may seem ‘logical’ for forestry to adapt now to future climate change: it epitomises an industry where actions taken today will determine long-term development, given that trees will not be harvested until 70–90 years after planting. However, the sector has taken limited actions to adapt, despite an abundance of available information on the impacts of climate change — such as storms, drought and changes in insect population.




climate

Finding finance for climate change adaptation

Additional funding mechanisms are required to finance adaptation to climate change in developing countries, according to a new study. The study predicts how relationships between costs associated with adapting to and mitigating against climate change, and costs associated with damages caused by climate change, will progress over the next century.

Mutual trust between coastal stakeholders key to successful climate change adaptation

A lack of trust between stakeholders, planners and decision makers in coastal Portugal is obstructing adaptation to climate change plans, finds a new study. The researchers suggest that building trust between stakeholders and coastal managers could lead to improved participation and dialogue for future planning, financing and implementation of coastal adaptation.
