The critical role crops play in the Earth's CO2 cycle
December 4, 2014 01:13 PM - Kelly April Tyrrell, University of Wisconsin - Madison.

Each year, the planet balances its budget. The carbon dioxide absorbed by plants in the spring and summer as they convert solar energy into food is released back to the atmosphere in autumn and winter. Levels of the greenhouse gas fall, only to rise again.

But the budget has gotten bigger. Over the last five decades, the magnitude of this rise and fall has grown nearly 50 percent in the Northern Hemisphere, as the amount of the greenhouse gas taken in and released has increased. Now, new research shows that humans and their crops have a lot to do with it, highlighting the profound impact people have on the Earth’s atmosphere.

O Christmas Tree, O Christmas Tree
December 3, 2014 10:18 AM - Allison Winter, ENN

The tradition of the Capitol Christmas Tree, or The People’s Tree, began in 1964 when Speaker of the U.S. House of Representatives John W. McCormack (D-MA) placed a live Christmas tree on the Capitol lawn. This tree lived three years before succumbing to wind and root damage. In 1970, the Capitol Architect asked the U.S. Forest Service to provide a Christmas tree. Since then, a different national forest has been chosen each year to provide The People’s Tree. This national forest also works with state forests to provide companion trees that are smaller Christmas trees for offices in Washington, D.C. 

 

This year, the 88-foot-tall white spruce tree was harvested from the Chippewa National Forest in northeastern Minnesota by Jim Scheff who won the Logger of the Year award from the Sustainable Forestry Initiative Inc. (SFI). 

 

That begs the question how can a logger win an award from a sustainability group? 

UK considers sustainable aviation fuel

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?
December 1, 2014 12:09 PM - Michigan State University

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.
