UK considers sustainable aviation fuel
December 2, 2014 12:57 PM - ClickGreen Staff, ClickGreen

A coalition of the UK’s airlines, airports, manufacturers and air navigation service provider NATS, has launched its latest industry road map, which considers the opportunities for sustainable aviation fuels. The Sustainable Aviation (SA) research identifies the potential for a 24 per cent reduction in aviation carbon dioxide emissions by 2050 and the generation of £265 million in economic value plus the creation of 4,400 jobs in the UK over the next 15 years.

New study links carbon emissions and climate warming
December 2, 2014 07:44 AM - University of Southampton via ScienceDaily.

Research has identified, for the first time, how global warming is related to the amount of carbon emitted.

”čA team of researchers from the universities of Southampton, Bristol and Liverpool have derived the first theoretical equation to demonstrate that global warming is a direct result of the build-up of carbon emissions since the late 1800s when human-made carbon emissions began. The results are in accord with previous data from climate models.

The theoretical equation reveals the complex relationship between carbon dioxide levels and the ocean system. Burning fossil fuels increases atmospheric carbon dioxide levels leading to global warming and the greenhouse effect, which is partly offset by the oceans taking in both heat and carbon.

What Drives the Global Warming Debate?

Scientists have presented the most comprehensive evidence to date that climate extremes such as droughts and record temperatures are failing to change people’s minds about global warming. Instead, political orientation is the most influential factor in shaping perceptions about climate change, both in the short-term and long-term, said Sandra Marquart-Pyatt, a Michigan State University sociologist and lead investigator on the study.

Education is a key to climate change adaption
December 1, 2014 05:19 AM - ClickGreen staff, ClickGreen

Given that some climate change is already unavoidable investing in empowerment through universal education should be an essential element in climate change adaptation efforts, which so far focus mostly in engineering projects, according to a new study from the International Institute for Applied Systems Analysis (IIASA).

The article draws upon extensive analysis of natural disaster data for 167 countries over the past four decades as well as a number of studies carried out in individual countries and regions, published last year in a special issue of the journal Ecology and Society.
 

How dangerous ARE fracking chemicals really?
November 28, 2014 09:17 AM - University of Colorado Boulder

The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder.

Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.

Europe's Plastic Bag Agreement Contested by Industry
November 26, 2014 09:14 AM - Ecaterina Casinge, EurActiv

As lawmakers reached agreement this week to limit the use of plastic bags across Europe, industry voices warned that such rules will have a negative impact on trade in Europe's internal market. The ban could also lead to different standards in legislation in member states and ultimately, to a ban on other types of packaging, according to PlasticsEurope, the association of plastics manufacturers. The European Parliament and the Council agreed on Friday (21 November) on EU-wide legislation obliging member states to reduce the use of plastic bags. The law will apply only to bags with a thickness below 0.05mm, because they are less reusable, and turn into waste more quickly.

Establishing marine protected areas to fight illegal fishing
November 25, 2014 09:10 AM - Kerry Klein, MONGABAY.COM

Do you know how that tuna sashimi got to your dinner plate? Probably not—and chances are, the restaurant that served it to you doesn’t know, either. A new policy paper argues that illicit fishing practices are flying under the radar all around the world, and global society must combat them in order to keep seafood on the menu. According to the paper, published in Science, fishing practices that are illegal, unreported and unregulated (collectively referred to as IUU) are ubiquitous. They range from bottom trawlers scouring the seafloor—sometimes catching more illegal species than legal ones—to small boats simply not reporting their catch. 

Farms as sites for renewable energy
November 21, 2014 07:00 AM - ClickGreen Staff, ClickGreen

UK farms could be a major player in a shift towards a resilient, low-carbon energy system, according to a landmark report launched today by the Farm Power coalition. 

The coalition, which is made up of a growing number of farming bodies, businesses and NGOs, are now calling on policymakers and other key stakeholders, including supermarkets, to support the renewable energy vision.

The research carried out by sustainability non-profit Forum for the Future, which leads the coalition, and Nottingham Trent University, found there was at least 10GW of untapped resource across UK farms – equivalent to more than three times the installed capacity of the proposed new nuclear power plant at Hinkley Point C.

Not so fast: Planting trees might cause warming?
November 20, 2014 03:29 PM - Bristol University

Afforestation (planting trees) to mitigate climate change could cause warming rather than cooling globally due to non-carbon effects of land use change, according to new research from the University of Bristol.

Global land use change and its interaction with the climate system is recognised as an important component of the Intergovernmental Panel on Climate Change (IPCC)’s future climate scenarios.
