Beware The Blob
There has been plenty of discussion of El Niño, the periodic weather phenomenon in which prevailing easterly winds in the Pacific Ocean weaken, allowing warm water to move eastward and wreak havoc with the weather in North and South America. The current El Niño is a particularly strong one; some say it may be one of the strongest ever and are calling it the “Godzilla El Niño.”
The Second Hottest Year On Record
According to the National Oceanic and Atmospheric Administration – or NOAA – 2015 was the second hottest year ever recorded in the contiguous United States.
Wild Bee Loss Puts Crops At Risk
Between 2008 and 2013, the United States lost nearly a quarter of its wild bees. Some 39% of our nation’s croplands rely on pollinators. Important farming regions – from California’s Central Valley to the Midwest’s Corn Belt – are among the areas grappling with wild bee declines.
California’s Methane Leak
It’s being called the largest environmental disaster in California’s history. On October 23, 2015, a massive natural gas leak erupted at a storage well operated by Southern California Gas in Aliso Canyon, outside of Los Angeles. The leak has forced more than 2,800 families from their homes, and to make that worse, they have no idea when they’ll be able to return.
Road Salt
Snow season is here. The chances are good you’ll find yourself behind a truck spreading salt on the roads in an attempt to deice them. You may even try a little salt on your own front porch. Annually we spread about 20 million tons of road salt in the U.S., and we’ve been doing it since the late 1930s.
The World’s Lakes Are Heating Up
Climate change is causing the world’s lakes to warm, with repercussions for fisheries and freshwater supplies. So reports an ambitious new study, funded by NASA and the National Science Foundation, and recently published in Geophysical Research Letters.
China And Renewable Energy
When it comes to carbon dioxide, three countries are responsible for half of the world’s emissions into the atmosphere: China, the US, and India. On a per capita basis, we are far worse than China, but its population is so huge that that it produces twice as much CO2 as the United States and nearly one-third of the world’s emissions.
Is Natural Gas Cleaner Than Coal?
The widespread use of hydraulic fracturing (or fracking) as well as improved drilling techniques have created a major boom in natural gas production. This unquestionably has positive economic impacts for many. One of the important consequences of this is that natural gas is increasingly taking the place of coal for powering electrical generating plants.
Food Deserts
A food desert is a geographic area – often an urban area – where affordable and nutritious food is difficult to obtain, particularly for those without access to an automobile. Food deserts disproportionately affect occupants of poor, low-income neighborhoods where there are often no groceries stores or farmer’s markets. These are places were food comes from convenience stores or fast-food chains. More than 20 million Americans are thought to live in food deserts.
Composting Pays
Many people compost their food scraps and yard waste because they think it is the right thing to do. In some places, like San Francisco and Seattle, there is curbside pickup available to have these organic materials composted.
Toward Safer Produce
Government and private organizations have long been encouraging us to eat healthier diets. We have seen food pyramid charts for decades and the “5 a day” campaign has boosted our consumption of fresh fruits and vegetables.
The Power Of Exercise
Many people often complain about not having enough time to exercise. But what if exercising for one hour could power your home for twenty-four hours? Would that be enough motivation?
Climate Change And The Global Food System
One of the most troubling aspects of global climate change is its potential impact on the production, distribution and quality of food. A report issued at the 2015 Paris Climate Conference focused on identifying climate change impacts on global food security. Food security is the ability of people to obtain and use sufficient amounts of safe and nutritious food. Even without the impact of climate change, food security is a challenge because of increasing population, poverty, and changing eating habits.

Bromated Flour
Nothing evokes an image of wholesomeness like a loaf of crusty, fresh-baked bread. But the flour used in some baked goods may contain an additive that’s been linked to cancer.
Antibiotic Apocalypse
Virtually everyone listening to this radio segment has relied on antibiotics to treat a bacterial infection. Since the 1940’s, we’ve used antibiotics to combat everything from strep throat to sinus infections. They also play an important role in surgery and cancer therapies.
Biodiversity And Our Diet
We often talk about the importance of biodiversity in maintaining the health of ecosystems. One ecosystem we don’t often think about in those terms is the human diet.
Microplastics And Salt
Today, thousands of personal care products – such as facial scrubs, body washes, and toothpastes – are known to contain minuscule balls of plastic called microbeads. When we shower or brush our teeth, these microbeads are washed down the drain and travel undetected through wastewater treatment plants. When they reach their final destination — our lakes, rivers and oceans — they mix with other sources of microplastics, including industrial waste and degraded plastic litter.
Beavers: Nature’s Nitrogen Busters
Beavers are one of nature’s most industrious engineers. Using branches and mud, the intrepid animals create dams that slow moving water. In New York’s Hudson Valley, their constructions are a common sight on streams and in wetlands.
Climate Opinions
An international poll of over 45,000 people in 40 countries looked at opinions about climate change and the need to curb greenhouse gas emissions. The results are quite interesting.
