EPA Proposes Approval of New Climate-Friendly Refrigerants
In support of President Obama's Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is proposing to increase the options for refrigerants in the United States that offer better climate protection without harming the ozone layer. This is the agency's first action that addresses refrigerants under the Climate Action Plan, which calls on EPA's Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals. >> Read the Full Article
Connecting population growth and biodiversity decline
It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billionâ€”for a total of 11 billionâ€”by century's end. Despite this few scientists, policymakers, or even environmentalists are willing to publicly connect incredible population growth to worsening climate change, biodiversity loss, resource scarcity, or the global environmental crisis in general. >> Read the Full Article
Farmed fish, the dark side
It seems as more and more of the fish available to us in the supermarket and in restaurants is farmed. Is this good or bad? Probably a bit of both. Raising fish in fish farms doesn't impact the wild fish to any great extent, but fish farms must be well situated, and well run to prevent problems. They are not natural ecosystems! Aquaculture has become a booming industry in Chile, with salmon and other fish farmed in floating enclosures along the South Pacific coast. But as farmers densely pack these pens to meet demand, diseases can easily pass between fish â€” for example, an outbreak of infectious salmon anemia that emerged in 2007 caused the deaths of more than a million fish and threatened to cripple the industry. And unsustainable aquaculture methods can have a wider impact, spreading disease to the worldâ€™s already vulnerable ocean fisheries and contaminating the environment. >> Read the Full Article
Choosing the Right Path: How Air Travel Affects Climate Change
It has been well documented that one negative of air travel â€“ besides the food â€“ is the emission of CO2 from jet engines. But what about contrails? Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishingâ€™s journal Environmental Research Letters. According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2. >> Read the Full Article
Solar Power Meets Half of Germany's Energy Demand
A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists. >> Read the Full Article
Getting a better handle on CO2, NASA will help!
From all the news about how anthropogenic emissions of CO2 are increasing tremendously (remember the hockey stick graph?) you would think that these emissions are causing all the atmospheric increases of CO2. And, our use of fossil fuels is increasing exponentially, with more than half of all fossil fuels ever used by humans being consumed in the last 20 years. However, in comparison with the amount of carbon that enters the atmosphere from natural sources, our fossil fuel emissions are modest. "Carbon dioxide generated by human activities amounts to only a few percent of the total yearly atmospheric uptake or loss of carbon dioxide from plant life and geochemical processes on land and in the ocean," said Gregg Marland, a professor in the Geology Department of Appalachian State University, Boone, North Carolina. "This may not seem like much, but humans have essentially tipped the balance." >> Read the Full Article
Bio-fuel from Whisky distilling in Scotland
Edinburgh-based biofuel company Celtic Renewables has signed an agreement with Europeâ€™s foremost biotechnology pilot facility to undergo next-stage testing of its process to turn whisky by-products into biofuel that can power current vehicles. The partnership, which will allow the company to develop its technology at Bio Base Europe Pilot Plant (BBEPP) in Ghent, has been made possible by second round funding worth â‚¬1.5million, including more than â‚¬1million from the UK Government, to help meet its ambition of growing a new â‚¬125 million-a-year industry in the UK. >> Read the Full Article

New independent report identifies challenges facing U.S. businesses and policymakers; describes strategies to avoid significant, unequally-spread economic disruptions. The American economy faces major risks from climate change, including damaging coastal storms, growing heat-related mortality, and declining labor productivity, according to an independent report released today by business, education and political leaders. >> Read the Full Article
For healthy oceans, end illegal fishing: WWF
Last week, Secretary of State John Kerry brought together some of the world's leading thinkers to chart a path for securing the future of our planetâ€™s oceans and the communities and economies they support. Leaders from more than 80 countries delved into the most pressing issues facing our oceans, including marine pollution, climate change and unsustainable fisheries. >> Read the Full Article
Coal mines to Solar PV in UK
Energy specialists Anesco is to undertake a major regeneration of a number of former colliery sites with the development of a 30MW solar portfolio. The ground-mounted solar installations will be operational for 25 years and, once completed, will generate enough low-carbon energy to provide powerfor around 10,000 homes, while saving up to 15 tonnes of carbon per year. >> Read the Full Article
