Scientists Warn of Air Pollution Risks in West Africa
August 21, 2015 01:55 PM - University of York
New research by European and African scientists, including a team from the University of York, warns of the risks posed by the increasing air pollution over the cities of West Africa – amid fears it could have an impact on human health, meteorology and regional climate.
China's carbon emissions may be lower than estimated
August 20, 2015 01:30 PM - Eliza Berlage, The Ecologist
The IPCC has over-estimated China's emissions since 2000 by 14%, almost 3 gigatonnes of carbon since 2000, while its energy consumption has been 10% higher than realised, writes Eliza Berlage. The country is far more carbon-efficient than we ever knew.
Air pollution in China is bad, REALLY bad!
August 20, 2015 08:28 AM - RP Siegel
There can be no question that the epic story of our time is our struggle to endure against the threatening demons of our own creation. In that story, China must be the sleeping giant. As the story opens, the giant awakens, searching for a way to improve the livelihood of his people, inadvertently trampling on a number of the Earth’s delicate structures in doing so. Realizing this, a second awakening occurs. But can the giant change direction quickly enough, before too much harm is done?
The damage that re-directed the giant was the realization that fossil fuel emissions, particularly from coal-fired power plants, are pushing atmospheric carbon levels to dangerously high levels. China’s emissions have grown 7 percent annually — far faster than the rest of the world, which is growing at 2.8 percent. Now that we all realize that emissions have to start decreasing, fast, China has pledged to achieve peak emissions by 2030, after which its emissions will begin to decrease.
Dissecting the Farm-to-Table Fable
August 18, 2015 09:17 AM - Jan Lee, Triple Pundit
The vibrant, mega-million-dollar farm to table movement is under increasing scrutiny these days. In San Diego, where produce is an $1.8 billion industry and year-round farmers markets can be found in almost every neighborhood (one of the few financial spinoffs of climate change, perhaps), the farm-to-table concept is getting a bad rep.
What you should know about America's Clean Power Plan
August 3, 2015 08:30 AM - Gina McCarthy, USEPA
Today, President Obama will unveil the U.S. Environmental Protection Agency’s (EPA’s) Clean Power Plan—a historic step to cut the carbon pollution driving climate change. Here are six key things every American should know...
Making Tastier Wines with Fewer Pesticides
July 30, 2015 09:00 AM - American Chemical Society
Wine-making is steeped in age-old traditions, but to address the threat of pests and concerns over heavy pesticide use, vintners are turning to science. With the goal of designing better grape breeds, scientists are parsing the differences between wild American grapes — which make terrible wine but are pest-resistant — and the less hardy grape species pressed for fine wines worldwide. They report their findings in ACS’ Journal of Agricultural and Food Chemistry.
Offshore Wind Power Comes to the US
July 29, 2015 03:33 PM - S.E. Smith, Care2
The United States marked an energy milestone this week as construction began on a pilot offshore wind program that will be used to test the economic feasibility of offshore wind energy. According to the Bureau of Energy, some four million megawatts of power lie in wait off the coasts and the shores of regions like the Great Lakes, where wind blusters far stronger than it does on land — and even a few miles an hour makes a big difference with turbines.
Canada ranks #2 for most LEED buildings
July 28, 2015 01:24 PM - Roy L Hales, ECOreport
Though LEED is not the world’s only green building rating system, it is the most widely used and recognized. Thus it is no small thing that, for the second year in a row, Canada is #2 for LEED building in the World.
How Corn Became King
July 28, 2015 09:12 AM - Kelly April Tyrrell, University of Wisconsin-Madison
Ten thousand years ago, a golden grain got naked, brought people together and grew to become one of the top agricultural commodities on the planet.
Now, University of Wisconsin-Madison researchers have found that just a single letter change in the genetic script of corn's ancestor, teosinte, helped make it all possible.
Publishing in the journal Genetics this month, UW-Madison genetics Professor John Doebley and a team of researchers describe how, during the domestication of corn, a single nucleotide change in the teosinte glume architectural gene (tga1) stripped away the hard, inedible casing of this wild grass, ultimately exposing the edible golden kernel.
California Farmers Switch to Less Thirsty Crops
July 28, 2015 08:56 AM - Lesley McClurg, NPR
Water scarcity is driving California farmers to plant different crops. Growers are switching to more profitable, less-thirsty fruits, vegetables and nuts.
