"How do we achieve food security in the face of climate change? Answering this question means weaving together many strands of evidence about our complex food and climate systems to produce a clear image. In response to this challenge, the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), with support from the Global Donor Platform for Rural Development, convened the Commission on Sustainable Agriculture and Climate Change, thirteen senior scientists working on agriculture, climate, nutrition, economics and natural resources in governmental, academic and civil society institutions around the world."

"Earth Day 2013 came and went in April with the usual fanfare of green festivals, volunteer programs, company campaigns and reflections on the question, "How are we doing, anyway?" On this last point, the answer this year seemed to be a somewhat lukewarm, "Well…we've been better.""

"The term sustainability has been stretched to become almost meaningless. It's time to talk about regeneration, writes Herbert Girardet"

"Due to Sweden's innovative waste-to-energy program and highly efficient recycling habits, the Scandinavian nation faces an interesting dilemma. They have run out of trash."

"There have been quite a few headlines lately about the record amounts of solar power getting built in China. In 2013, the country added at least 12 gigawatts of solar capacity - 50 percent more than any country has ever built in a single year. Impressive. But let's also put this in context. China is a massive country and is building lots of everything. And last year it added far more fossil-fuel output capability than it did solar, wind, hydro and nuclear power combined."

"Two of Australia's World Heritage listed places have made the headlines in the last week. The Great Barrier Reef Marine Park Authority gave the go-ahead for silt from a government-approved dredging operation to be dumped within the World Heritage listed park boundaries. And the federal government announced that it was seeking to have a recent extension of Tasmania's World Heritage listed forests partially overturned. What is World Heritage listing and why is it important?"

"Obama has set a new goal of having 20 percent of the federal government's energy use come from renewable power by 2020, which includes the Army, Navy, and Air Force deploying a combined 3 gigawatts of renewable energy by the end of the decade."

"Remember carbon capture and storage? Five years ago, the idea of grabbing the carbon dioxide from coal and gas power plants and burying it deep underground was considered an essential technology for curbing the world's greenhouse-gas emissions. A diagram of how various sorts of carbon capture might work. (Congressional Budget Office) But carbon capture hasn't fared well in the years since. Since 2008, world governments committed at least $25 billion to fund large-scale demonstration projects, the Financial Times reports. And we have remarkably little to show for it so far."

"December 02, 2009 , 9:24 AM by Prue Bentley In the last 24 hours, Tony Abbott has come under fire for his comments on the veracity of climate change. The media has seized on his claim to a small local Victorian paper that "climate change is crap". In the context of his leadership this is curious as Mr Abbott seems to have spun 180 degrees in his estimation of human influenced climate change in as little as a few hours / votes. The paper in question happened to be the Pyrenees Advocate and the Editor of the paper, Craig Wilson, was there when those words were uttered."

"Renewable energy effectively uses natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are naturally replenished. Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and biofuels for transportation."
